Description

LED base plate structure

Technical field

The utility model relates to a kind of LED light fixture member, particularly a kind of LED base plate structure.

Background technology

At present, known LED (Light Emitting Diodes light emitting diode) fitting structure, each LED integration group is located on the base plate surface, this base plate group is located at the predetermined position of light fixture again; Above-mentioned known base plate, often be designed to flat shape, therefore when each LED group is located at above it, the crevice projection angle of its light is consistent direction, so cause the concentrated and narrow and small problem of ray cast area, and in order to allow the ray cast area of whole light fixture can obtain the effect of comparatively wide expansion, must be further during production adjust angle at the LED of regional area, so obviously cause the increase on the process operations, and along with LED is provided with increasing of quantity, the adjustment that must expend also will prolong relatively man-hour with, therefore, existing LED base plate does not have good industrial economy benefit.

In addition, also there is the dealer to attempt the bigger reflector of production refraction angle in the hope of producing the ray cast effect that broad expands, still, the situation that the reflector that refraction angle is bigger will cause irradiates light intensity to weaken relatively, and then can't reach good illuminating effect really; And the light exposure intensity of known LED light fixture and the projection distance relation of being inversely proportional to, even the angle of its LED is adjusted to some extent, the illumination on photographed object surface still can't reach equally distributed effect, the problem that exists peripheral luminosity to successively decrease.

The utility model content

Technical problem to be solved in the utility model provides a kind of LED base plate structure, and this base plate structure has the advantages that making is simple fast, efficient is high and have good industrial economy benefit.

For solving the problems of the technologies described above, the utility model LED base plate structure, it comprises a plate body, the front group of described plate body is provided with a plurality of LED that are distributed in distance; Described plate body is arranged to step-like meander-shaped, positive forms the dual terrace surface at least with class's difference at it, and the changing towards having angle difference of its different terraces, and described LED is configured on each terrace.

The utility model LED base plate structure, has class's difference and towards the design of the terrace shape and structure of angle difference by it, each LED group is located at after the LED base plate, can directly reach ray cast angle difference changes shape, need not carry out indivedual adjustment of LED again, and described terrace shape is one-body molded in making LED base plate process, thus extremely fast simple on making, can simplify processing procedure, lifting production efficiency really and reduce cost, realize preferable industrial economy benefit.

The specific embodiment

The utility model provides a kind of LED base plate structure, in order to solve the problem that processing procedure complexity, efficient are low and economic benefit is not good that existing LED base plate exists, below in conjunction with accompanying drawing the utility model is elaborated.

See also shown in Figure 1, the preferred embodiment of the utility model LED base plate structure; Described LED base plate 10 is a plate body, has positive 11 and one back side 12, and the front group of described plate body is provided with a plurality of LED20 that are distributed in distance; The material of this LED base plate 10 can adopt the preferable copper coin of thermal conductivity; LED base plate 10 is arranged to the shape of step-like complications, terrace A1, A2, A3, A4, A5, A6 that its positive 11 formation have class's difference, and the changing towards having angle difference of its different terraces, the LED20 of described different angles is configured on each terrace A1, A2, A3, A4, A5, the A6.

Wherein, LED base plate 10 back sides 12 can be formed with recessed edge portion 13 at described different terrace A1, A2 phase joining place, as shown in Figure 2; LED base plate 10 back sides 12 can be organized and be provided with heat pipe 30, and this heat pipe 30 can be fitted in the aforementioned recessed edge portion 13, and then makes heat pipe 30 obtain comparatively firm assembled state.

As shown in Figure 2, the concrete enforcement shape that shows different terraces towards the angle difference variation; The terrace A6 of these LED base plate 10 fronts, 11 the most close first ends (i.e. right-hand end among the figure) is made as the level angle state, again with progressively each terrace A5, A4, A3, A2, the A1 of close LED base plate 10 positive 11 second ends (i.e. left-hand end among the figure) are the shape that is provided with that strengthens the angle of inclination in regular turn; And, the LED illumination that the LED illumination that the big terrace in this angle of inclination is disposed is disposed greater than the less terrace in angle of inclination.The LED20B of the big illumination of terrace A1, A2 (promptly far away) configuration that the angle of inclination is bigger apart from shone thing, less terrace A4, the A5 (promptly nearer apart from shone thing) in angle of inclination then disposes the LED20C of less illumination, and the terrace A6 that is level angle among the figure then disposes the LED20 of littler illumination.

As shown in Figure 3, two sides of described single terrace A1 can be formed with inclined plane part 40, and the design of inclined plane part 40 whereby makes the LED20B that is configured in this position produce outward-dipping state, reaches the effect of further amplification ray cast area.

As Fig. 4, Fig. 5, shown in Figure 6, described LED base plate 10 is assembled in the example in the fitting structure, described light fixture 50 can be provided with a groove 51 and set position wherein (as by bolt lock prescription formula) for 10 groups of this LED base plates, and 30 of its heat pipes can be connected with the set radiating seat 52 of light fixture 50 and be beneficial to heat radiation.

As shown in Figure 7, the utility model LED base plate 10 designs by described planform, when its

integral LED

20,20B, 20C are lit in shone thing 60 throw lights, have class's difference and, reach the effect of amplification ray cast area by it towards the terrace A1-A6 shaped design of angle difference; In addition, the design of the big illuminance LED 20B of terrace A1, A2 configuration that described angle of inclination is bigger, mainly be that the illumination of projection distance LED20B far away is strengthened, so that the ray cast face of integral LED (with regard to being radiated at same plane object) illumination can be more even, improve the problem that the ray cast face periphery luminosity of general light fixture successively decreases.

Main effect of the present utility model is as follows:

1, the utility model is by having class's difference and towards the design of the terrace shape and structure of angle difference, after making each LED group be located at the LED base plate, can directly realize the shape that the ray cast angle difference changes, so compare with known configurations in the prior art, then need not carry out indivedual adjustment actions of LED, and described terrace shape can be one-body molded in making LED base plate process, so make extremely fast simply, can simplify processing procedure really, promote production efficiency and the preferable industrial economy benefit that reduces cost.

2, the utility model is by big terrace disposes LED illumination greater than the structural design that disposes LED illumination at the less terrace in angle of inclination at the angle of inclination, makes the ray cast face illumination of integral LED can be more even, reaches the purpose of lifting lighting quality.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not confined to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
