Description
Technical field
The present invention relates to LED.
Background technology
There is because of LED the advantages such as light efficiency is high, rich color, life-span length, in every field, more and more extensive to the application of LED, particularly in stage, view, certainly, in daily illumination, LED is also at alternative traditional light fixture, particularly LED lamp tube gradually.
Be disclose a kind of LED lamp tube in the patent document of 2011.4.27 as be 201010598934.1 applyings date at application number being 2010.12.21 publication date, comprise lampshade, lamp body and heat-dissipating casing, lamp body is arranged on heat-dissipating casing, lampshade is provided with projection, heat-dissipating casing is provided with breach, and described projection is inserted or extracts breach, and described lampshade and heat-dissipating casing form a cavity, lamp body is positioned at described cavity, substrate side and lamp body one-body molded.The LED lamp tube of said structure, when one-body molded body and substrate, technique is more complicated, cost is higher, and in addition, substrate only has dual-side to be connected with body, its heat transfer area is little, the efficiency of direct heat transfer is low, and like this, the partial heat on substrate can only be scattered and disappeared by substrate ability, therefore, radiating effect is bad.
At present, also has a kind of LED lamp tube, its substrate is by the form holding of holding on lamp body, be disclose a kind of LED lamp tube in the patent document of 2012.2.1 as be 201110228909.4 applyings date at application number being 2011.8.6 publication date, specifically disclose it and comprise lampshade, carrying lamp plate, driving power, lamp socket, left end cap and right end cap, lampshade and lamp socket semicircular in shape, lampshade inwall is provided with overhead kick, inboard wall of lamp holder is provided with draw-in groove I, draw-in groove II, draw-in groove III, overhead kick is embedded into draw-in groove II and makes lampshade and lamp socket be fastenedly connected formation round lamp tube each other, accommodation space is formed at round lamp tube endoporus, carrying lamp plate and driving power is provided with in accommodation space, the holding of carrying lamp plate is on draw-in groove I, lamp pearl is arranged on carrying lamp plate, in this structure, carrying lamp plate can be equivalent to substrate, left end cap and right end cap are embedded into the inwall of lamp tube ends.The defect of this LED lamp tube is: must need to arrange draw-in groove to the installation of carrying lamp plate, but when making carrying lamp plate, if the width of carrying lamp plate is too wide too thick, then cannot be inserted in draw-in groove, if carrying lamp plate is too narrow and too thin, then carry lamp plate be installed in draw-in groove have after both there is gap, carrying lamp plate can rock in draw-in groove, if the width of carrying lamp plate is less than the spacing between two draw-in grooves, then carrying lamp plate cannot be installed, therefore, the restriction by draw-in groove of the width of lamp plate and thickness is carried; And when carrying lamp plate and draw-in groove has gap, then carrying lamp plate and lamp socket can not close contact, and carrying equals also little with the contact area of lamp socket, then the transmission of heat is restricted, and like this, the partial heat on carrying lamp plate can by transfer of air on lamp socket, then, through lamp socket dissipated heat, thus reduce the speed of heat loss, cause radiating effect bad.
Summary of the invention
The object of this invention is to provide a kind of LED pipe type lamp, utilize structure of the present invention, can radiating effect be improved, be convenient to mount and dismount substrate, reduce the production cost of LED pipe type lamp.
For achieving the above object, a kind of LED pipe type lamp, comprise lamp body, lampshade, substrate and LED light source, lampshade is arranged on lamp body, is formed with cavity between lampshade and lamp body; LED light source is arranged on substrate; Lamp body has base plate carrying plate, and substrate is connected with base plate carrying plate by buckle; Described buckle comprises body, the blocking part of extend laterally from body more than two, from body to the elastic portion of more than two of downward-extension and the insertion section that is connected to elastic portion, insertion section has outside projection; Described blocking part is positioned at the top of substrate and contacts with substrate, and elastic portion is through substrate and base plate carrying plate, and described projection is positioned at the below of base plate carrying plate, and projection contacts with base plate carrying plate; Substrate is more than two, and wherein one end of substrate is welded with connecting line, is provided with the electric-connected socket coordinated with Electric plug with shutter at the other end of substrate; Between adjacent substrate, Electric plug with shutter is plugged on electric-connected socket; Electric plug with shutter and electric-connected socket fixed by snap.
Said structure, because substrate is connected on base plate carrying plate by buckle, and buckle has blocking part, elastic portion and insertion section, and buckle during insertion, the hole of substrate and base plate carrying plate is passed by insertion section, elastic portion deforms simultaneously, and when the projection of insertion section is positioned at the below of base plate carrying plate, elastic portion resets, blocking part and substrate contacts, like this, under the effect of protruding and blocking part, by substrate and base plate carrying plate fitting together tightly.By above-mentioned fixed structure, substrate and base plate carrying plate can be made tightly to fit, and both contacts area are large, the reliability of heat transfer and the speed of heat transfer can be improved, the most of heat on substrate is made to be delivered on lamp body outer surface by base plate carrying plate, therefore, good heat dissipation effect.Relative to prior art, owing to not needing draw-in groove to fix substrate, therefore, width and the thickness of substrate do not limit by draw-in groove, according to the Demand Design substrate of LED light source, like this, can reduce the cost of substrate.In addition, by the buckle fixing base of structure of the present invention, because buckle has elastic portion, therefore, be convenient to mount and dismount substrate.In said structure, realize the connection between substrate by connecting line, Electric plug with shutter and electric-connected socket, can realize connecting fast and dismantling, and when the LED light source on a certain substrate or substrate is damaged, repair and replacement fast can be realized.
As specializing, described blocking part comprises the stretch section that is connected with body and with being connected to stretch section keeps out projection.Described blocking part has a stretch section, can allow and keep out protruding generation elastic deformation and screen resilience, make to keep out projection and obtain more tight with substrate contacts, thus it is more tight that substrate is contacted with base plate carrying plate, to improve radiating effect.
As improvement, described body is provided with press section.By arranging press section, be then convenient to buckle is installed.
As improvement, described lamp body comprises radiating shell and described base plate carrying plate, and base plate carrying plate and housing are structure as a whole, and are formed with cavity body between base plate carrying plate and radiating shell.
As improvement, radiating shell is provided with radiating fin, to improve area of dissipation, thus improves radiating effect further.
As improvement, described buckle is non-conductive Elastic buckle, and it is more tight that elastically-deformable restoring force makes substrate contact with base plate carrying plate, and non-conductive Elastic buckle guarantees that substrate is non-conductive contact with base plate carrying plate, avoids lamp body surface leakage.
