Description

本発明は、半導体発光素子であるＬＥＤを用いた直管形ランプに関し、特に筐体への透光部材の組付けに関する。   The present invention relates to a straight tube lamp using an LED, which is a semiconductor light emitting element, and more particularly to the assembly of a translucent member to a housing.

近年省エネ対策として、光源を白熱電球より蛍光灯あるいは、より省エネを図るためにＬＥＤなどの半導体光学素子を使った直管形ランプやそれを備えた照明装置を使用する動きが高まっている。光源に半導体光学素子を用いると、蛍光灯より長寿命で、経時での点滅やちらつきがない等のメリットがある。
特許文献１では、長尺形の基板と、この基板に実装された発光素子と、基板の長手方向の両端部側にそれぞれ配設され、照明器具のソケットに装着される接続ピンと、透光性の樹脂からなり、接続ピンが相対的に変位可能であり、かつ外方に突出するように基板を覆う包囲体とを備えた発光素子ランプにおいて、係止片及び係合凹部が、包囲体の長手方向において少なくとも２箇所に形成され、取付け体の長手方向の両端面及びカバー体の長手方向の両端面が同一面状となるようにして、係止片の係止爪を係合凹部に係止させることにより、取付け体及びカバー体を一体化する構成が開示さていれる。
特許文献２では、半円筒部と平板部とからなる放熱性を有する長尺の半円筒形筐体と、筐体の平板部側に取り付けられ、筐体の半円筒部の外径とほぼ同じ外径を有する半円形状の透光性カバーと、筐体の平板部外側に密着して取り付けられ、複数のＬＥＤを長手方向に沿って所定間隔で搭載した長尺のＬＥＤ実装基板とからなり、筐体の空洞部内に、ＬＥＤ実装基板に実装されたＬＥＤに電流を供給する電源基板及び電源用電線を収納したＬＥＤ照明装置において、筐体の平板部の両側にカバー取付溝を設け、透光性カバーの両端の突条部を装着することにより固定するようにした構成が開示さていれる。
特許文献３では、ベースの上端部に形成される挿入部と、キャップの下端部に形成され、挿入部に結合される対応挿入部とを含んでなり、ベースとキャップの着脱の際、挿入部と対応挿入部が弾性を発揮して着脱されることにより、ベースとキャップの結合及び分離の容易性を保障する着脱手段をさらに含んでなり、挿入部は、ベース上端部から内側に向かって突出する挿入突起と、挿入突起によって形成される挿入溝とを含み、対応挿入部は、キャップの下端部から外側に向かって突出して挿入溝に結合される対応挿入突起と、対応挿入突起の上部に形成され、挿入突起が結合される対応挿入溝と、対応挿入突起の対向面に形成され、対応挿入突起が挿入溝に結合するとき、挿入溝を形成する内壁に沿って入る傾斜部とを含むことを特徴としたＬＥＤ蛍光灯が開示されている。 In recent years, as an energy saving measure, there has been an increasing movement to use a fluorescent lamp as a light source rather than an incandescent bulb, or a straight tube lamp using a semiconductor optical element such as an LED or a lighting device including the same in order to save energy. When a semiconductor optical element is used as the light source, there are advantages such as longer life than fluorescent lamps and no flickering or flickering over time.
In Patent Document 1, a long substrate, a light emitting element mounted on the substrate, connection pins disposed on both ends in the longitudinal direction of the substrate, and attached to a socket of a lighting fixture, and translucency In the light emitting element lamp, the connecting pin is relatively displaceable and includes an enclosure that covers the substrate so as to protrude outward. It is formed in at least two places in the longitudinal direction, and the both end faces in the longitudinal direction of the attachment body and the both end faces in the longitudinal direction of the cover body are flush with each other, and the engaging claws of the engaging pieces are engaged with the engaging recesses. The structure which unifies an attachment body and a cover body by making it stop is disclosed.
In Patent Document 2, a long semi-cylindrical housing having heat dissipation composed of a semi-cylindrical portion and a flat plate portion, and the outer diameter of the semi-cylindrical portion of the housing attached to the flat plate portion side of the housing are almost the same. It consists of a semi-circular translucent cover having an outer diameter and a long LED mounting board mounted in close contact with the outer side of the flat plate portion of the housing and mounting a plurality of LEDs at predetermined intervals along the longitudinal direction. In the LED lighting device in which the power supply board for supplying current to the LEDs mounted on the LED mounting board and the power supply wires are housed in the hollow portion of the housing, cover mounting grooves are provided on both sides of the flat plate portion of the housing. The structure which fixed by attaching the protrusion part of the both ends of an optical cover is disclosed.
Patent Document 3 includes an insertion portion formed at the upper end portion of the base and a corresponding insertion portion formed at the lower end portion of the cap and coupled to the insertion portion. The insertion portion further includes attachment / detachment means for ensuring the ease of coupling and separation of the base and the cap when the insertion portion is attached / detached with elasticity, and the insertion portion protrudes inward from the upper end portion of the base. An insertion groove formed by the insertion protrusion, the corresponding insertion portion protrudes outward from the lower end of the cap and is coupled to the insertion groove, and an upper portion of the corresponding insertion protrusion. And a corresponding insertion groove to which the insertion protrusion is coupled, and an inclined portion formed along the inner wall that forms the insertion groove when the corresponding insertion protrusion is coupled to the insertion groove. With features LED fluorescent lamp is disclosed a.

特許文献１では、カバー体に設けた２箇所以上の係止爪を、取付体の該当する位置に設けた係合凹部にはめ込むようにしているが、１ｍ以上の直管形の長手カバー体を押出し成形以外の方法で成形する場合、金型が大きくなり、金型コストがかかり不経済である。また、部分的にしか係合していないので、カバー体成形時にソリがあった場合、ＬＥＤの温度上昇でさらにソリが大きくなり、引っ掛かり量が減少することでちょっとした振動でも係合が外れ、カバー体が落下することが考えられる。さらに、引っ掛け部の幅が狭いためフック部が折れやすく、白化した状態で引っ掛かっていることも考えられ、カバー体の重量により落下の心配がある。
特許文献２では、筐体の平板部の両側にはカバー取付溝が設けられていて、取付方法については言及されていないが、カバーを溝に沿って挿入する方法であろうと予想する。この取付方法を採用すると、筐体の長さとカバーの長さを加えた以上の長さのスペ−スが必要であり、挿入するのに時間を要する。仮に筐体の取付溝にカバー突状部を引っ掛けて取り付けようとすると、取付溝のスペ−スが狭く、回転させる際に突状部が取付溝に引っ掛かって破損してしまう。また、回転支点とは逆側の突状部が筐体の取付溝の上のレ−ルにぶつかって破損したり、取り付け溝に入らなかったりすることが考えられる。
特許文献３では、キャップをベースに挿入する際、片側を引っ掛けて回転させようとするほど両者の隙間が確保されていないため、回転させて装着することはできず、長手方向にスライドしてキャップを装着するしかない。また両側を同時に引っ掛けようとすると、キャップの内側方向に挿入部を曲げることになり、蛍光灯に類似するような直径が小さい半円をさらに小さくするのは大きな力が必要で、キャップの挿入部に大きな力がかかるため、破損することが考えられる。また、長手方向に距離がある（４０形で１ｍ以上）ため、保持した状態を維持することが難しく、両手の作業でも難しいので、治具や工具が必要になりコストがかかってしまう。
本発明は、低コストで破損のおそれが少なく、透光部材の装着状態が安定して作業性のよいＬＥＤ直管形ランプ及び照明装置を提供する。 In Patent Document 1, two or more locking claws provided on the cover body are fitted into engagement recesses provided at corresponding positions of the attachment body. However, a straight tube-shaped longitudinal cover body of 1 m or more is used. When molding by a method other than extrusion molding, the mold becomes large, and the mold cost is high, which is uneconomical. In addition, since it is only partially engaged, if there is a warp when forming the cover body, the warp becomes larger as the LED temperature rises, and the amount of hooking decreases, so even a slight vibration can disengage and the cover It is possible that the body falls. Further, since the hook portion is narrow, the hook portion is easily broken, and it may be caught in a whitened state, and there is a fear of dropping due to the weight of the cover body.
In Patent Document 2, cover mounting grooves are provided on both sides of the flat plate portion of the housing, and the mounting method is not mentioned, but it is expected that the method is to insert the cover along the groove. When this mounting method is adopted, a space longer than the length of the casing and the length of the cover is required, and it takes time to insert the space. If the cover protrusion is hooked on the mounting groove of the housing to be attached, the space of the mounting groove is narrow, and the protrusion hooks into the mounting groove and is damaged when rotating. Further, it is conceivable that the protruding portion on the opposite side to the rotation fulcrum hits the rail on the mounting groove of the housing and is damaged or does not enter the mounting groove.
In Patent Document 3, when the cap is inserted into the base, the gap between the two is not secured so as to be hooked and rotated. Therefore, the cap cannot be rotated and mounted, and the cap slides in the longitudinal direction. There is no choice but to install. Also, if you try to hook both sides at the same time, the insertion part will be bent in the direction of the inside of the cap, and it is necessary to use a large force to further reduce the semicircle with a small diameter similar to a fluorescent lamp. Since a large force is applied to this, it can be considered to be damaged. In addition, since there is a distance in the longitudinal direction (1 meter or more in 40 shape), it is difficult to maintain the held state, and it is difficult to work with both hands, so jigs and tools are required and costs increase.
The present invention provides an LED straight tube lamp and an illuminating device that are low in cost, less likely to be damaged, have a light-transmitting member mounted in a stable state, and have good workability.

It can be connected to an illuminating lamp through caps arranged at both ends located in the longitudinal direction of the light member, and a part of the translucent member is opened in the longitudinal direction and intersects the longitudinal direction. The housing has protrusions on both sides of the opening located in the width direction, and the housing has a fitting portion into which the protrusion is inserted in the width direction intersecting the longitudinal direction, and an inclined portion adjacent to at least one of the fitting portions. One of the fitting portions when mounting the translucent member to the housing After fitting one protrusion, the other protrusion of the translucent member is in contact with the inclined portion of the housing with the fitting location as the center of rotation, and then inserted into the other fitting of the housing It is characterized by having comprised so that it may fit.
The LED straight tube lamp according to the present invention has a cylindrical shape whose cross section is substantially the same in the longitudinal direction, and is made of a metal and has a longitudinal shape mounted on a mounting substrate on which a plurality of semiconductor light emitting elements are mounted at the center of the cylindrical cross section. And a translucent member that is integrated with and in contact with the casing and is made of a resin that transmits a light beam from the semiconductor light emitting element and that extends in the longitudinal direction, and is positioned in the longitudinal direction of the casing and the translucent member In the LED straight tube lamp that can be attached to the illuminating lamp through caps arranged at both ends, the translucent member is partially opened in the longitudinal direction, and in the width direction intersecting the longitudinal direction. The housing has projections on both sides of the opening, and the housing has a fitting portion into which the projection portion is inserted in the width direction intersecting with the longitudinal direction, and an inclined portion adjacent to each fitting portion. When attaching a member to the housing, the protrusions on both sides are After each contact, the protrusion is pressed from the direction substantially orthogonal to the straight line connecting the protrusions of the translucent member, so that the protrusions are respectively inserted and fitted into the fitting parts. .

本発明によれば、半導体発光素子からの光束を透過する樹脂製で長手方向に延びる透光部材の一部を長手方向に開口し、長手方向と交差する幅方向に位置する開口両端に突起部を設け、長手方向に延びる筐体の幅方向に突起部が挿入される嵌合部と、少なくとも一方の嵌合部に隣接した傾斜部を有し、透光部材を筐体に装着する際、一方の嵌合部と一方の突起部とを嵌合させた後、当該嵌合箇所を回転中心として、透光部材の他方の突起部が筐体の傾斜部と接した後、筐体の他方の嵌合部に挿入して嵌合するように構成したので、長手方向に延びる透光部材が押出成形による製作が可能なのでコストをかけずに作ることができる。また、透光部材の突起部が嵌合部に入った状態で長手方向にわたって嵌合しているので両者の引っ掛かり量が確保され、振動などで嵌合が外れるおそれが極めて少なくなり、装着状態が安定して作業性がよくなる。さらに、透光部材を筐体に装着するとき、スライドさせなくても装着できるので、筐体の長さのスペ−スで着脱作業ができ、時間をかけなくてもセットできるので作業性がよい。
樹脂製の透光部材の幅方向に位置する開口両端に突起部を設け、一方の嵌合部と一方の突起部とを嵌合させた後、当該嵌合箇所を回転中心として、透光部材の他方の突起部が筐体の傾斜部と接させた後、筐体の他方の嵌合部に挿入するので、透光部材の広がりやすい方向に弾性変形するので、小さな力で突起部を嵌合部に挿入でき、治具や工具を用いる必要がなく、低コストで組立時の作業性もよくなるとともに、弾性範囲内で着脱作業ができるので、突起部が破損するおそれも極めて少なくなる。 According to the present invention, a part of a translucent member made of a resin that transmits a light beam from a semiconductor light emitting element and extending in the longitudinal direction is opened in the longitudinal direction, and protrusions are formed at both ends of the opening located in the width direction intersecting the longitudinal direction.

In addition, since the protrusion of the translucent member is fitted in the longitudinal direction with the fitting part in the fitting part, the amount of both of them is secured, and the possibility of disengagement due to vibration etc. is extremely reduced, and the wearing state is reduced. Stable workability is improved. In addition, when the translucent member is attached to the housing, it can be attached without sliding, so that it can be attached and detached in the space of the length of the housing, and can be set without taking time, so workability is good. .
Protrusion portions are provided at both ends of the opening located in the width direction of the resin-made translucent member, and after fitting the one fitting portion and the one projection portion, the translucent member with the fitting portion as the rotation center After the other projection of the first contact with the inclined portion of the housing is inserted into the other fitting portion of the housing, it is elastically deformed in the direction in which the translucent member easily spreads. Since it can be inserted into the joint, it is not necessary to use a jig or a tool, the workability at the time of assembly is improved at a low cost, and the attachment / detachment work can be performed within the elastic range, so that the possibility of breakage of the protrusion is extremely reduced.

Power is being supplied. The semiconductor light emitting elements (LEDs) 8a and 8b emit light when supplied with power.

キャップ１ａ、１ｂの端子４ａ、４ｂから供給される電流が交流の場合、直流に変換する必要があるが、この場合、筐体２の筒部分に図示しない変換基板を内蔵しておくことも可能である。あるいは、照明灯具１５０に変換機能を持つようにして、端子４ａ、４ｂに直流電流を供給しても良い。図２に示す端子４ａ、４ｂに接続されたコネクタ９のリ−ド線６ａ、６ｂを流れる電流が交流、直流どちらであっても、本発明を満足させることは可能である。図２においてキャップ１ａ側のコネクタ９の表記は省略している。   When the current supplied from the terminals 4a and 4b of the caps 1a and 1b is alternating current, it is necessary to convert it to direct current. In this case, a conversion board (not shown) can be built in the cylindrical portion of the housing 2. It is. Alternatively, the illuminating lamp 150 may have a conversion function, and a direct current may be supplied to the terminals 4a and 4b. The present invention can be satisfied regardless of whether the current flowing through the lead wires 6a and 6b of the connector 9 connected to the terminals 4a and 4b shown in FIG. In FIG. 2, the notation of the connector 9 on the cap 1a side is omitted.

筐体２は、断面が長手方向において略同一の筒形状であり、アルミニウム合金やマグネシウム合金などの軽量で、放熱性の良い材料が用いられている。筐体２は押出し成形により形成されるが、板金などを折り曲げることによって製作することも可能である。   The casing 2 has a cylindrical shape whose cross section is substantially the same in the longitudinal direction, and is made of a lightweight material with good heat dissipation, such as an aluminum alloy or a magnesium alloy. The housing 2 is formed by extrusion molding, but can be manufactured by bending a sheet metal or the like.

筐体２は、図３にも示すように、筒形状の断面中央部に平坦部２２が形成されている。この平坦部２２には、粘着性を有するシート状樹脂部材１０が貼り付けられている。シート状樹脂部材１０には、長手方向に複数個並べられた半導体発光素子８ａ、８ｂを搭載した実装基板７ａ、７ｂが接着されている。これに平坦部２２に実装基板７ａ、７ｂが固定される。本形態において、半導体発光素子８ａ、８ｂは、２枚の実装基板７ａ、７ｂに装着されているが、１枚の実装基板あるいは３枚以上の実装基板に搭載した形態であってもよい。シート状樹脂部材１０には、熱伝導性の良い材料を用いている。シート状樹脂部材１０を必要としない場合は、ネジを使って実装基板７ａ、７ｂを平坦部２２に固定してもよい。   As shown in FIG. 3, the housing 2 has a flat portion 22 formed at the center of the cylindrical cross section. An adhesive sheet-like resin member 10 is affixed to the flat portion 22. Mounted on the sheet-like resin member 10 are mounting substrates 7a and 7b on which a plurality of semiconductor light emitting elements 8a and 8b arranged in the longitudinal direction are mounted. The mounting substrates 7 a and 7 b are fixed to the flat portion 22. In the present embodiment, the semiconductor light emitting elements 8a and 8b are mounted on the two mounting boards 7a and 7b, but may be mounted on one mounting board or three or more mounting boards. The sheet-like resin member 10 is made of a material having good thermal conductivity. When the sheet-like resin member 10 is not required, the mounting boards 7a and 7b may be fixed to the flat portion 22 using screws.

筐体２には、その長手方向と交差する幅方向に、凹部２１a、２１ｂと、凹部２１a、２１ｂに隣接した傾斜部２０ａ、２０ｂが、長手方向に延在するように形成されている。傾斜部２０ａは、一端が平坦部２２と接続し、他端が凹部２１aと接続されている。傾斜部２０ｂは、一端が平坦部２２と接続し、他端が凹部２１ｂと接続されている。すなわち、傾斜部２０ａ、２０ｂは、平坦部２２と凹部２１a、２１ｂの間に形成されている。凹部２１ａと凹部２１ｂは、長手方向から見た形状が、曲面となる、Ｕ字形状あるいは半円形状に形成されている。本形態ではＵ字形状とされている。   The casing 2 is formed with recesses 21a and 21b and inclined portions 20a and 20b adjacent to the recesses 21a and 21b extending in the longitudinal direction in the width direction intersecting the longitudinal direction. The inclined portion 20a has one end connected to the flat portion 22 and the other end connected to the recess 21a. The inclined portion 20b has one end connected to the flat portion 22 and the other end connected to the recess 21b. That is, the inclined portions 20a and 20b are formed between the flat portion 22 and the concave portions 21a and 21b. The concave portion 21a and the concave portion 21b are formed in a U shape or a semicircular shape whose shape viewed from the longitudinal direction is a curved surface. In this embodiment, it is U-shaped.

カバー３は、断面形状が略同一で、押出成形や射出成形によって長手方向に延びるように成形された樹脂製で構成されている。カバー３は、半導体発光素子８ａ、８ｂからの光束を透過させるために拡散剤を入れた乳白色や透明な材料で製造されている。本形態において、カバー３は筐体２と組み合わせて一体化することで、断面円形状になるような構成を採っているが、楕円や長方形の断面にしてもよい。   The cover 3 has substantially the same cross-sectional shape, and is made of a resin molded so as to extend in the longitudinal direction by extrusion molding or injection molding. The cover 3 is made of milky white or a transparent material containing a diffusing agent so as to transmit light beams from the semiconductor light emitting elements 8a and 8b. In this embodiment, the cover 3 is combined with the housing 2 and integrated so as to have a circular cross section. However, the cover 3 may have an elliptical or rectangular cross section.

図３に示すように、カバー３は、その一部が長手方向に向って開口されていて、半円弧形状とされている。カバー３は、長手方向と交差する幅方向に位置する開口両側３ａ、３ｂの円内側に、突起部３０ａ、３０ｂが長手方向に延在するように形成されている。突起部３０ａ、３０ｂは、長手方向から見た形状が断面円形状とされている。突起部３０ａ、３０ｂは、凹部２１ａ、２１ｂにそれぞれ挿入されることで、凹部２１ａ、２１ｂと嵌合する大きさと形状に形成されている。   As shown in FIG. 3, a part of the cover 3 is opened in the longitudinal direction and has a semicircular arc shape. The cover 3 is formed so that the protrusions 30a and 30b extend in the longitudinal direction on the inner sides of the opening sides 3a and 3b located in the width direction intersecting the longitudinal direction. The protrusions 30a and 30b have a circular cross section when viewed from the longitudinal direction. The protrusions 30a and 30b are formed in sizes and shapes that fit into the recesses 21a and 21b by being inserted into the recesses 21a and 21b, respectively.

突起部３０ａ、３０ｂは、突起部３０ａ、３０ｂが凹部２１ａ、２１ｂに挿入された状態で、筐体２からカバー３が外れない程度の突起部３０ａ、３０ｂの間隔に設定されている。凹部２１ａと突起部３０ａとの嵌合箇所には、当該嵌合箇所を回転中心として回動できる位の隙間が形成されている。また、突起部３０ａと突起部３０ｂの間隔が最大になる角部２３ａ、２３ｂでも弾性範囲内となるように、両者の間隔が設定されている。その際、カバー３の突起部３０ａ、３０の角部３１ａ、３１ｂにも応力集中し易いため、ピン角とならないように、角部２３ａ、２３ｂをＲ形状としている。   The protrusions 30a and 30b are set at intervals between the protrusions 30a and 30b so that the cover 3 cannot be removed from the housing 2 in a state where the protrusions 30a and 30b are inserted into the recesses 21a and 21b. A gap is formed at the fitting portion between the recess 21a and the protrusion 30a so that the fitting portion can be rotated about the fitting portion. In addition, the distance between the protrusions 30a and the protrusions 30b is set so that the corners 23a and 23b where the distance between the protrusions 30a and 30b is within the elastic range. At that time, since the stress is easily concentrated on the corners 31a and 31b of the protrusions 30a and 30 of the cover 3, the corners 23a and 23b are formed in an R shape so as not to have a pin angle.

弾性部材で構成されたカバー３は、長手方向に開口されているので、円弧形状の径を小さくする方向には大きな力を要するが、矢印Ｗ１で示す径を開いて大きくする方向には小さな力でカバー３を撓ませることが可能である。   Since the cover 3 made of an elastic member is opened in the longitudinal direction, a large force is required to reduce the diameter of the arc shape, but a small force is required to increase the diameter indicated by the arrow W1. It is possible to bend the cover 3 with.

次に、カバー３の筐体２への第１の装着形態について説明する。
まず、図３、図４に示すように、長手方向に延在する一方の突起部３０ａを長手方向に延在する凹部２１ａ内に幅方向から挿入しておき、長手方向に延在する他方の突起部３０ｂを長手方向に延在する傾斜部２０ｂに乗せて置く。この形態のように、凹部２１ａを使用してカバー３を装着する（組み立てる）場合には、傾斜部２０ｂが１箇所あれば充分である。しかし、図３、図４に示すように傾斜部２０ａ、２０ｂを筐体２の両側に形成しておくことで、装着する（組み立ての）際の基準を、凹部２１ａ側ではなく、凹部２１ｂ側とすることができる。このため、筐体２の平坦部２２の両端に傾斜部２０ａ、２０ｂを設けておいた方が作業性の多様化を図ることができるので好ましい。 Next, the 1st mounting | wearing form to the housing | casing 2 of the cover 3 is demonstrated.
First, as shown in FIGS. 3 and 4, one protrusion 30a extending in the longitudinal direction is inserted from the width direction into the recess 21a extending in the longitudinal direction, and the other extending in the longitudinal direction is inserted. The protruding portion 30b is placed on the inclined portion 20b extending in the longitudinal direction. When the cover 3 is mounted (assembled) using the recess 21a as in this embodiment, it is sufficient if there is one inclined portion 20b. However, by forming the inclined portions 20a and 20b on both sides of the housing 2 as shown in FIGS. 3 and 4, the reference for mounting (assembling) is not the concave portion 21a side but the concave portion 21b side. It can be. For this reason, it is preferable to provide the inclined portions 20a and 20b at both ends of the flat portion 22 of the housing 2 because workability can be diversified.

次に図３に示すように、カバー３に矢印Ｂ方向へのモ−メント、すなわち、カバー３を筐体２に向って押し込む方向へのモーメントを加えると、傾斜部２０ｂと突起部３０ｂの接触部２４が傾斜部２０ｂを図中、右下方向に下りながら移動することで、カバー３が幅方向に徐々に広がっていき、突起部３０ｂと突起部３０ａの間隔が広くなる。そして、接触部２４が角部２３ｂを超えると、カバー３の広がりが解消されて、突起部３０ｂが元に戻ろうとする力で凹部２１ｂ内に挿入されて嵌合し、図５に示すように、筐体２に装着された状態となる。   Next, as shown in FIG. 3, when a moment is applied to the cover 3 in the direction of arrow B, that is, a direction in which the cover 3 is pushed toward the housing 2, the contact between the inclined portion 20b and the protruding portion 30b. As the portion 24 moves down the inclined portion 20b in the lower right direction in the drawing, the cover 3 gradually spreads in the width direction, and the interval between the protruding portion 30b and the protruding portion 30a becomes wider. Then, when the contact portion 24 exceeds the corner portion 23b, the spread of the cover 3 is eliminated, and the projection portion 30b is inserted and fitted into the recess portion 21b with a force to return, as shown in FIG. Then, it is in a state of being mounted on the housing 2.

このような直管形ランプ１００の構成とすると、長手方向に延びるカバー３が押出成形による製作が可能なのでコストをかけずに製造することができる。カバー３の突起部３０ａ、３０ｂが凹部２１ａ、２１ｂに入った状態で長手方向にわたって嵌合しているので、両者の引っ掛かり量が確保され、振動などで嵌合が外れるおそれが極めて少なくなり、装着状態が安定して作業性がよくなる。さらに、カバー３を筐体２に装着する時に、嵌合箇所を回転中心として回動させることで装着できるので、スライド動作をしなくてよく、筐体２の長さのスペ−スで着脱作業ができ、時間をかけなくても装着できるので作業性がよい。   With such a configuration of the straight tube lamp 100, the cover 3 extending in the longitudinal direction can be manufactured by extrusion molding, so that it can be manufactured without cost. Since the protrusions 30a and 30b of the cover 3 are fitted over the longitudinal direction with the recesses 21a and 21b being inserted, the amount of both hooks is secured, and the possibility of disengagement due to vibration or the like is extremely reduced. The condition is stable and workability is improved. Furthermore, when the cover 3 is attached to the housing 2, it can be attached by rotating the fitting part around the center of rotation, so there is no need for sliding operation, and the attaching / detaching work is performed in the space of the length of the housing 2. It can be installed without taking time, so workability is good.

樹脂製のカバー３の幅方向に位置する開口両端３ａ、３ｂに突起部３０ａ、３０ｂを設け、一方の凹部２１ａと一方の突起部３０ａとを嵌合させた後、当該嵌合箇所を回転中心として、カバー３の他方の突起部３０ｂが傾斜部２０ｂと接した後、他方の凹部２１ｂに挿入して嵌合するので、カバー３の広がりやすい方向に弾性変形するので、小さな力で突起部３０ｂを凹部２１ｂに挿入でき、治具や工具を用いる必要がなく、低コストで組立時の作業性もよくなるとともに、弾性範囲内で着脱作業ができるので、突起部３０ａ、３０ｂが破損するおそれも極めて少なくなる。   Protrusions 30a and 30b are provided at the opening ends 3a and 3b located in the width direction of the cover 3 made of resin, and after fitting the one recess 21a and the one protrusion 30a, the fitting portion is the center of rotation. Then, after the other protrusion 30b of the cover 3 is in contact with the inclined portion 20b, it is inserted into the other recess 21b so as to be elastically deformed in the direction in which the cover 3 is easy to spread. Can be inserted into the recess 21b, it is not necessary to use a jig or a tool, the workability at the time of assembly is improved at a low cost, and the attaching / detaching operation can be performed within the elastic range, so that the protrusions 30a and 30b are very likely to be damaged. Less.

このため、低コストで作業性がよく、破損のおそれが少なく、カバー３の装着状態が安定する直管形ランプ１００となる。
本形態のように突起部３０ｂの形状を断面円形にしておけば、傾斜部２０ｂと接触部２４との接点が点接触に近づき（長手方向では線接触）、摩擦係数を小さくできるので、突起部３０ｂに挿入しやすくなる。 Therefore, the straight tube lamp 100 is low in cost, has good workability, is less likely to break, and has a stable mounting state of the cover 3.
If the shape of the protrusion 30b is circular as in this embodiment, the contact point between the inclined part 20b and the contact part 24 approaches point contact (line contact in the longitudinal direction), and the friction coefficient can be reduced. It becomes easy to insert in 30b.

図６を用いてカバー３の筐体２への第２の装着形態について説明する。
本形態では、双方の突起部３０ａ、３０ｂを傾斜部２０ａ、２０ｂに接触させてカバー３を筐体２に向って押し込むことで、突起部３０ａ、３０ｂを凹部２１ａ、２１ｂに略同時に挿入して嵌合させて装着するものである。 The 2nd mounting | wearing form to the housing | casing 2 of the cover 3 is demonstrated using FIG.
In this embodiment, both the protruding portions 30a and 30b are brought into contact with the inclined portions 20a and 20b and the cover 3 is pushed toward the housing 2, so that the protruding portions 30a and 30b are inserted into the recessed portions 21a and 21b substantially simultaneously. It is fitted and fitted.

本形態の場合、カバー３を筐体２に装着する際、両側の突起部３０ａ、３０ｂを傾斜部２０ａ、２０ｂにそれぞれ接触させる。その後に、カバー３の突起部３０ａ、３０ｂを結ぶ直線Ｌに略直交する方向（本形態では図６の上方）からカバー３に力Ｐ１を加圧する。すると、カバー３が、図中下方に移動して突起部３０ａと突起部３０ｂが幅方向に下りながら傾斜部２０ａ、２０ｂ上を移動することで、カバー３が徐々に幅方向に広がっていき、突起部３０ｂと突起部３０ａの間隔が広くなる。そして、傾斜部２０ａ、２０ｂと凹部２１ａ、２１ｂの境目となる角部２３ａ、２３ｂを突起部３０ａ、３０ｂが超えると、開く方向に弾性変形したカバー３の復元力により突起部３０ａ、３０ｂが凹部２１ａ、２１ｂ内に挿入されて嵌合し、図５に示すように、筐体２に装着された状態となる。   In the case of this embodiment, when the cover 3 is attached to the housing 2, the projecting portions 30a and 30b on both sides are brought into contact with the inclined portions 20a and 20b, respectively. Thereafter, a force P1 is applied to the cover 3 from a direction substantially orthogonal to the straight line L connecting the protrusions 30a and 30b of the cover 3 (in the present embodiment, the upper side in FIG. 6). Then, the cover 3 moves downward in the figure, and the cover 3 gradually spreads in the width direction by moving on the inclined portions 20a and 20b while the protrusion 30a and the protrusion 30b descend in the width direction. The distance between the protrusion 30b and the protrusion 30a is increased. When the protrusions 30a and 30b exceed the corners 23a and 23b that are the boundaries between the inclined portions 20a and 20b and the recesses 21a and 21b, the protrusions 30a and 30b are recessed by the restoring force of the cover 3 that is elastically deformed in the opening direction. It is inserted into 21a and 21b and fits into the housing 2 as shown in FIG.

本形態のように、カバー３を筐体２に装着する際、カバー３の幅方向に位置する開口両端３ａ、３ｂに設けた突起部３０ａ、３０ｂを、筐体２の幅方向に設けた凹部２１ａ、２１ｂと隣接した傾斜部２０ａ、２０ｂにそれぞれ接触させた後に、突起部３０ａ、３０ｂを結ぶ直線Ｌに略直交する方向から加圧することで、突起部３０ａ、３０ｂを凹部２１ａ、２１ｂにそれぞれ挿入して嵌合するので、一方向からの加圧操作でカバーを筐体２に装着することができる。このため、特別な習熟等不要となって、装着時の作業性がよくなる。   As in this embodiment, when the cover 3 is attached to the housing 2, the protrusions 30 a and 30 b provided at the opening ends 3 a and 3 b located in the width direction of the cover 3 are provided in the recesses provided in the width direction of the housing 2. After contacting the inclined portions 20a and 20b adjacent to 21a and 21b, respectively, the protrusions 30a and 30b are respectively applied to the recesses 21a and 21b by applying pressure from a direction substantially perpendicular to the straight line L connecting the protrusions 30a and 30b. Since it is inserted and fitted, the cover can be attached to the housing 2 by a pressure operation from one direction. This eliminates the need for special learning and improves workability during mounting.

図７に示すように、傾斜部２０ａ、２０ｂの表面に白色又は白色を基調とする色を塗装あるいは印刷して着色すると、筐体２（傾斜部）の地肌を突起部３０ａ、３０ｂを直に滑らすよりも摩擦係数を低下させることができるので、さらに小さな力でカバー３を筐体２に装着することができる。このため、カバー３の挿入が容易になり、挿入時の引っ掛かりによる破損の心配がなくなるとともに、傾斜部２０ａ、２０ｂで滑らせる時にカバー３が削れてカバー内部に落下し、削れカスによる影を生じさせるような不具合をも防止することができる。   As shown in FIG. 7, when the surface of the inclined portions 20a and 20b is painted or printed with a color based on white or white, the background of the housing 2 (inclined portion) is directly attached to the protruding portions 30a and 30b. Since the friction coefficient can be reduced rather than sliding, the cover 3 can be attached to the housing 2 with a smaller force. For this reason, the cover 3 can be easily inserted, and there is no fear of breakage due to catching at the time of insertion, and the cover 3 is scraped off when it is slid by the inclined portions 20a and 20b, and falls into the cover, and a shadow caused by scraped scraps is generated. It is possible to prevent such a problem.

また、図７に示すように、直管形ランプ１００を矢印Ｅで示す半導体発光素子８ａ、８ｂから光が照射される方向から見た場合、傾斜部２０ａ、２０ｂにおいて金属の下地が見えていると、傾斜部２０ａ、２０ｂが影になっているように見える。このため、傾斜部２０ａ、２０ｂの表面２０１ａ、２０１ｂに白色又は白色を基調とする色の着色を施すと、各半導体発光素子の光束の一部５０ａがカバー３の内面で一部反射し、その光路５０ｂは傾斜部２０ａ、２０ｂで偏向して光路５０ｃとして折り返され、カバー３を透過して外部に放出されて、直管形ランプ１００を明るくすることができる。   Further, as shown in FIG. 7, when the straight tube lamp 100 is viewed from the direction in which light is emitted from the semiconductor light emitting elements 8a and 8b indicated by the arrow E, the metal base is visible at the inclined portions 20a and 20b. And it seems that the inclined parts 20a and 20b are shaded. For this reason, when the surfaces 201a and 201b of the inclined portions 20a and 20b are colored with white or a color based on white, a part of the light flux 50a of each semiconductor light emitting element is partially reflected on the inner surface of the cover 3, The light path 50b is deflected by the inclined portions 20a and 20b and is folded back as the light path 50c. The light path 50b passes through the cover 3 and is emitted to the outside so that the straight tube lamp 100 can be brightened.

すなわち、カバー３で反射した各半導体発光素子からの光がさらに傾斜部２０ａ、２０ｂの表面２０１ａ、２０１ｂで反射可能になるので、光効率を上げることができ、光量自体を下げる場合には、省エネになる。さらに、着色前の金属のままの色だと、カバー３側から見た時に傾斜部２０ａ、２０ｂの表面２０１ａ、２０１ｂが影のようになり、見た目が良くないが、光を反射する反射面として機能するように表面２０１ａ、２０１ｂに着色面とすることで、影がなくなり商品価値を向上させることができる。   That is, since the light from each semiconductor light emitting element reflected by the cover 3 can be further reflected by the surfaces 201a and 201b of the inclined portions 20a and 20b, the light efficiency can be increased, and energy can be saved when the light amount itself is decreased. become. Furthermore, if it is the color of the metal before coloring, the surfaces 201a and 201b of the inclined portions 20a and 20b look like shadows when viewed from the cover 3, and the appearance is not good, but it is a reflective surface that reflects light. By making the surfaces 201a and 201b colored so as to function, there is no shadow, and the commercial value can be improved.

また、カバー３に設けた突起部３０ａ、３０ｂと筐体２の傾斜部２０ａ、２０ｂは、嵌合前において常に線接触状態とされているので、筐体２との摩擦係数を低減でき、カバー３の挿入が容易になる。このため、挿入時の引っ掛かりによる破損の心配がなくなるとともに、傾斜部２０ａ、２０ｂで滑らせる時に樹脂製のカバー３が削れてカバー内部に落下し、削れカスによる影を生じさせるような不具合の発生もより確実に防止することができる。   Further, since the protrusions 30a and 30b provided on the cover 3 and the inclined portions 20a and 20b of the housing 2 are always in a line contact state before fitting, the friction coefficient with the housing 2 can be reduced, and the cover 3 is easy to insert. For this reason, there is no fear of damage due to catching at the time of insertion, and there is a problem that the resin cover 3 is scraped and falls into the cover when sliding on the inclined portions 20a and 20b, and a shadow caused by scraped scraps is generated. Can be more reliably prevented.
