Abstract
The utility model relates to an LED automobile headlamp, comprising LED light sources (3), a shell (5), a reflector (2) and lenses (1), wherein the lenses (1) and the reflector (2) are connected to form a reflection and refraction system, the reflector (2) is of an ellipsoid, the LED light source (3) is positioned a focus of the ellipsoid and a second focus of the ellipsoid is superposed with a focus of the lenses (1). The automobile headlamp also comprises a heat pipe (4), one end of the heat pipe is fixed with the shell (5), the other end of the heat pipe (4) stretches into the reflector (2), each LED light source (3) comprise an upper LED light source and a lower LED light source, and the two light sources are respectively fixed in the heat pipe (4) and stretch into one end of the reflector (2). The LED automobile headlamp has the advantage of high heat dissipation efficiency, and the conversion between far beam and dipped beam can be conveniently realized through the directivity of the LED light sources (3).
Description
Technical field
The utility model relates to a kind of car headlamp, belongs to the car light field.
Background technology
The led light source security reliability is strong, can accurately control light type and lighting angle, and is photochromic soft, and free from glare is not mercurous, the material of possibility such as sodium element health risk.For high-brightness LED, heat concentrates in the small-sized chip, and chip temperature raises, and causes the sharp decrease in efficiency of penetrating of non-uniform Distribution, chip light emitting efficient and fluorescent material of thermal stress; When temperature surpasses certain value (about 80 ℃), the component failure rate is index law to be increased.Statistics shows, 2 ℃ of the every risings of component temperature, reliability decrease 10%.When a plurality of LED dense arrangement were formed white lumination system, the dissipation problem of heat was more serious.It is low that the car headlamp of existing use led light source just exists radiating efficiency, the shortcoming that the life-span is short.Solve heat dissipation problem and become the prerequisite that high-brightness LED is used.
Summary of the invention
The purpose of this utility model provides a kind of radiating efficiency height, the car headlamp of distance light, dipped beam easy switching.
The technical scheme that realizes above-mentioned purpose is: a kind of LED car headlamp, comprise led light source, housing, speculum and lens, after linking to each other with speculum, lens forms the reflected refraction system, speculum is an ellipsoid, led light source is positioned at a focus place of this ellipsoid, and second focus of this ellipsoid overlaps with the focus of lens, also comprise heat pipe, one end of heat pipe is fixedlyed connected with housing, the other end stretches in the speculum, and led light source divides two up and down, and is separately fixed at heat pipe and stretches into a end in the speculum.
After adopting technique scheme, when the needs dipped beam, light a top led light source because LED light type and lighting angle controllability, light through speculum and lens after outgoing, can be met the dipped beam light type of national requirements GB4599.When the needs distance light, light up and down two led light sources together, light outgoing behind speculum and lens can be met the distance light light type of national requirements GB4599, thereby distance light, dipped beam switch very convenient.When led light source was lighted, heat pipe went above heat is dispersed into housing, utilize housing than area, promote the efficient of heat radiation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of LED car headlamp, comprise led light source 3, housing 5, speculum 2 and lens 1, after linking to each other with speculum 2, lens 1 forms the reflected refraction system, speculum 2 is ellipsoids, led light source 3 is positioned at a focus place of this ellipsoid, and second focus of this ellipsoid overlaps with the focus of lens 1, also comprise heat pipe 4, an end of heat pipe 4 is fixedlyed connected with housing 5, and the other end stretches in the speculum 2, two up and down of led light sources 3 minutes, and be separately fixed at heat pipe 4 and stretch into a end in the speculum 2.
As shown in Figure 1, two led light sources 3 are fixed on heat pipe 4 symmetrically and stretch into a end in the speculum 2.
Operation principle of the present utility model is as follows:
When the needs dipped beam, light a top led light source 3 because LED light type and lighting angle controllability, light through speculum and lens after outgoing, can be met the dipped beam light type of national requirements GB4599.When the needs distance light, light two led light sources 3 up and down together, through speculum 2 and lens 1 combination, can be met the distance light light type of national requirements GB4599.When led light source 3 was lighted, heat pipe 4 went above heat is dispersed into housing 5, utilize housing 5 than area, promote the efficient of heat radiation.
Claims (2)
1, a kind of LED car headlamp, comprise led light source (3), housing (5), speculum (2) and lens (1), after linking to each other with speculum (2), lens (1) forms the reflected refraction system, speculum (2) is an ellipsoid, led light source (3) is positioned at a focus place of this ellipsoid, and second focus of this ellipsoid overlaps with the focus of lens (1), it is characterized in that: also comprise heat pipe (4), one end of heat pipe (4) is fixedlyed connected with housing (5), the other end stretches in the speculum (2), and led light source (3) divides two up and down, and is separately fixed at heat pipe (4) and stretches into a end in the speculum (2).
2, LED car headlamp according to claim 1 is characterized in that: two led light sources (3) are fixed on heat pipe (4) symmetrically and stretch into the interior end of speculum (2).
