Abstract
An automobile LED headlamp comprises LED chips, a substrate and a line layer pressed on the substrate, wherein an installation seat is arranged on the substrate, a strip-shaped groove is formed on the installation seat; a plurality of LED chips are distributed in the strip-shaped groove; the LED chips are arrayed in a linear way; the inner wall of the strip-shaped groove is provided with a black light absorption layer; and the strip-shaped groove is filled with fluorescence glue. With the LED chips arrayed in a linear way, light extraction is limited by the strip-shaped groove, so strip-shaped light spots are formed for light spots of the light emitted; upon passing light illumination, the automobile LED headlamp is provided with light and shade cuff-off lines, so optical requirements of an automobile headlamp is met; and the black light absorption layer on the inner wall of the strip-shaped groove prevents reflection of light produced by the inner wall of the strip-shaped groove, so light extraction effect is guaranteed.
Description
Technical field
The utility model relates to LED lighting field, especially a kind of LED car headlamp.
Background technology
Along with the rise of LED, the application of LED illuminating lamp is more and more wider, and LED illumination in recent years has been applied in automobile lamp illumination.For car headlamp, because it to the requirement of optics is: in the time of dipped beam, need to have "cut-off"line.Throw light on as car headlamp using LED at present, for the requirement of headlamp before meeting, often need on light fixture, add extra optical accessories, as lens or reflector etc., these lens or reflector are generally complicated polymorphic structure could meet bright dipping requirement, thereby makes the overall structure of light fixture become complicated.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED car headlamp, meeting under the prerequisite of vehicle front lighting lamp optical requirement, simple in structure, easily manufactured.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED car headlamp, comprise LED chip, substrate and be pressed together on the line layer on described substrate, described substrate is provided with mount pad, described mount pad is provided with strip groove, is distributed with some LED chips in described strip groove, and described LED chip is word order, the inwall of described strip groove is provided with one deck black light-absorbing layer, in described strip groove, is filled with fluorescent glue.Because LED chip is word order, and its bright dipping is subject to the constraint of strip groove, and making its hot spot of being up to is strip light spots, and in the time of lower beam illumination, has "cut-off"line, meets the optics requirement of car headlamp; The black light-absorbing layer of strip groove inwall setting can prevent that strip groove inwall from producing reflection of light and affecting it and go out light effect.
As improvement, described substrate is ceramic substrate.
As improvement, described substrate back is provided with turmeric layer, and described substrate is connected with radiator melting by described turmeric layer.
The beneficial effect that the utility model compared with prior art brought is:
Because LED chip is word order, and its bright dipping is subject to the constraint of strip groove, and making its hot spot of being up to is strip light spots, and in the time of lower beam illumination, has "cut-off"line, meets the optics requirement of car headlamp; The black light-absorbing layer of strip groove inwall setting can prevent that strip groove inwall from producing reflection of light and affecting it and go out light effect.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model cross-sectional view.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of LED car headlamp, comprise LED chip 4, ceramic substrate 1 and be pressed together on the line layer on described ceramic substrate 1, described ceramic substrate 1 is provided with the mount pad 2 that is bar shaped, described mount pad 2 is provided with strip groove 3, is distributed with some LED chips 4 in described strip groove 3, and described LED chip 4 is word order, the inwall of described strip groove 3 is provided with one deck black light-absorbing layer 6, in described strip groove 3, is filled with fluorescent glue.
Described substrate back is provided with turmeric layer, and described substrate is connected with radiator 5 meltings by described turmeric layer, improves the radiating effect of ceramic substrate 1.
The utility model is because LED chip 4 is word order, and its bright dipping is subject to the constraint of strip groove, and making its hot spot of being up to is strip light spots, and in the time of lower beam illumination, has "cut-off"line, meets the optics requirement of car headlamp; The black light-absorbing layer 6 of strip groove 3 inwall settings can prevent that strip groove 3 inwalls from producing reflection of lights and affecting it and go out light effect.
