Have the advantages that luminosity is high, service life is long.LED has been widely used in illuminating lamp as light source.With people's life water
Flat raising, including live, build, business etc. more and more begin to use some be used for illuminate light fixture, in particular for
A kind of light fixture using LED as light source, to save the energy and increase lamp life.
And as the theory of " hommization illumination " is rooted in the hearts of the people, Lighting Design should build good house illumination or business is shone
Obvious results fruit, to meet the requirement of each side such as people's physiology, psychology.Particularly some store shelfs LED lamp use,
And the use in market or the LED lamp of the wine cabinet of house.As shown in figure 1, the structural representation for store shelf.The market
Shelf 10 comprise at least a top layer rack 11, a middle rack 12, and a bottom rack 13, and one
The LOGO racks 14 to be extended out from the middle rack 12.Generally light fixture is provided with the middle rack 12
15, the light fixture 15 at least needs to irradiate three positions, i.e., the LOGO set on described LOGO racks 14, on bottom rack 12
Goods, and the anterior position of bottom rack 12 is shown in dotted line.
As shown in Fig. 2 the structural representation for similar wine cabinet.The wine cabinet 20 includes a multilayer rack 21, Yi Jicong
The LOGO racks 22 to be extended out on the rack 21.The rack 21 for being typically due to wine cabinet 20 is made up of glass, therefore one
As light fixture 23 is provided with rack 21.The light fixture 23 at least needs to irradiate four positions, i.e., on any one rack 21
The goods of lower both sides, and the anterior position of rack both sides about 21, it is shown in dotted line.
The lighting angle of conventional lamp such as Halogen lamp LED or fluorescent lamp is 360 degree, it is contemplated that no matter in store shelf
On, or on wine cabinet, luminous the formed illumination of 360 degree of the angle is not all needed, that is, waste the light of a part.
The content of the invention
In view of this, it is necessary to a kind of bar shape LED lamp with specific light distribution angle is provided, to overcome above-mentioned deficiency.
A kind of bar shape LED lamp includes a lamp bracket, and the lamp bracket includes first light source and sets plane, one second
Light source sets plane, and the 3rd light source to set plane.Described first, second and the 3rd light source set plane section
Form an isosceles trapezoid.First light source sets the bottom that the section of plane is the isosceles trapezoid, and second, third light source is set
The section in horizontalization face is respectively the waist of the isosceles trapezoid.Second, third described light source sets the method along its light direction of plane
Line and the first light source set the angle between the normal along its light direction of plane to be both less than 115 degree and more than 90 degree.
Compared with prior art, there is first, second, third described light source of the lamp bracket of the bar shape LED lamp to set
Plane, and this first, second and the 3rd light source set plane and one isosceles trapezoid of section constitution, be advantageous to improve should
The versatility and interchangeability of bar shape LED lamp, and the adaptability of field of employment.And second, third described light source sets plane
Be both less than 115 degree and big along the angle between its light direction along what the normal of its light direction and the first light source set plane
Yu Du, the light source module group in plane is set to ensure to illuminate goods so that being arranged on first, second, third light source
Outside article in frame or wine cabinet, the eyes that light injects user are also prevented from, play the purpose of protection eye.

Embodiment
The specific embodiment of the present invention is further elaborated below based on accompanying drawing.It should be appreciated that this place is retouched
The specific embodiment stated only is used as embodiment, the protection domain being not intended to limit the present invention.
Fig. 3 and Fig. 4 is referred to, it is a kind of structural representation of bar shape LED lamp 100 provided by the present invention.It is described
Bar shape LED lamp 100 includes a lamp bracket 30, and at least two are arranged on the light source module group 40 on the lamp bracket 30, and one
The lampshade 50 being located on the lamp bracket 30.
The lamp bracket 30 can be made up of metal material, for carrying each members such as end cap, light source module 40, circuit board
Part.In the present embodiment, the lamp bracket 30 is molded by aluminium extruded.Because LED (not shown) is while electrified light emitting, meeting
The substantial amounts of heat of generation, the aluminium lamp bracket 30 help to radiate.The lamp bracket 30 includes first light source and sets plane 31, one the
Two light sources set plane 32, and the 3rd light source sets plane 33, and a lampshade clamping for being used to set the lampshade 50
Groove 34.In order to ensure the appearance and size of the lampshade 50 while ensure the Rational structure of following light source module groups 40, described first,
Second, third light source sets the cross-sectional length H perpendicular to length direction of plane 31,32,33 to be more than or equal to 7 millimeters.It is described
First, second, third light source sets the both sides of plane 31,32,33 to be respectively arranged with first buckling groove 311, the second clamping
Groove 321, the 3rd buckling groove 331.First, second, third buckling groove 311,321,331 is respectively used to card and sets described at least two
Individual light source module group 40.First, second, third light source sets one isosceles trapezoid of section constitution of plane 31,32,33.Institute
State the first light source and bottom of the plane 31 as the isosceles trapezoid is set, second, third described light source sets plane 32,33 to make respectively
For the waist of the isosceles trapezoid.First, second, third light source sets the section of plane 31,32,33 to be helped into isosceles trapezoid
In the interchangeability of the bar shape LED lamp 100, that is, be advantageous to different light source module groups under power transfer device 70 as described below it
Between luminous switching, to improve the versatility of whole light fixture and interchangeability.Due to light source module group 40 is separately positioned on described first,
In two or three in second, third light source setting plane 31,32,33, therefore first, second, third light source sets plane
31st, the position relationship between 32,33, angular relationship will determine the light direction of at least two light source module group 40, and two
The angle of the light direction of individual light source module group 40.Therefore, in order to reach between desired light direction and the plurality of light direction
Angle, second, third light source of the waist as isosceles trapezoid set the normal along its light direction of plane 32,33 with
The first light source as the bottom of isosceles trapezoid sets the included angle between the normal along its light direction of plane 31 will be small
In 115 degree and more than 90 degree.Please with reference to the light distribution curve of Fig. 5, Fig. 6 on certain shelf and wine cabinet.For Fig. 5, such as
Shown in irregular curve, it can be seen that light distribution of the bar shape LED lamp 100 on several sections in shelf use.It is right
In Fig. 6, as shown in irregular curve, the bar shape LED lamp 100 light intensity on several sections in wine cabinet use point can be seen
Cloth.In Fig. 5, Fig. 6, bent curvature of a curve is small will to be pointed at a distance, and curvature is big will be pointed into nearby, so that light direction
Angle less than 115 degree and more than under 90 degree, coordinate the effect of the lens bar 51 of following lampshades 40, light source module group can be made
40 light sent are all pointed into the goods in shelf or wine cabinet, while are also possible to prevent the eyes of its directive user, because ability
The technical staff in domain knows about LED and howsoever covered, and its intensity is all higher, can all make human eye uncomfortable.
