Abstract
The invention discloses a projected automotive headlamp with four ellipsoidal-surface LEDs (light-emitting diodes), comprising a support, wherein a convex lens is installed at the front end of the support, an aluminium substrate is arranged on the rear in the support, a light-shielding plate is installed at the middle of the support, two LED lamps are installed on the upper side surface and the lower side surface of the aluminium substrate respectively, and an ellipsoidal-surface reflector is arranged on the inner wall corresponding to each LED lamp, of the support. According to the invention, the LED light sources are small in volume, so that the interior layout of the lamp is more reasonable; the LED light sources are adopted, so that the temperature in the lamp can be reduced to be below 60 DEG C, the generation possibility of water mist is greatly decreased, and the service life of each component of the lamp can be prolonged; and via a design of semi-section, the light-emitting efficiency of the light sources is adequately utilized and the waste of light rays is reduced while the volumes are reduced, so that electricity can be saved by 70%.
Description
Technical field
The invention belongs to the automobile lamp field and other is used for the field of shot-light, relate in particular to a kind of car headlamp.
Background technology
Mostly traditional car headlamp is incandescent lamp, Halogen lamp LED if adopting, gas-discharge lamp etc. are as light source.Adopt the headlamp of projection, high beam light group, dipped headlights light group, projecting lamp light group have occupied most of volume of lamp body respectively, thereby whole lamp configuration design is very limited.After the tradition headlamp was lighted, temperature was higher in the lamp, very easily produces water smoke, influence other component life of outward appearance and lamp, and power consumption is also bigger, is unfavorable for energy-conservation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of energy savings, the life-span is long, volume is little four ellipsoid LED projection car headlamps.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of four ellipsoid LED projection automobile dipped headlights; Comprise support; The support front end is equipped with convex lens, and the rear portion is provided with aluminium base in the support, and mid-stent is equipped with shadow shield; Upper and lower two sides of aluminium base are equipped with two LED lamps respectively, are equipped with ellipsoidal mirror on the rack inner wall of each LED lamp correspondence.
Four LED lamps are housed on the aluminium base, and the light emission direction of adjacent LED lamp is opposite; Be respectively equipped with two ellipsoidal mirrors in the above and below of aluminium base.
The light that four LED lamps send converges at the intersection point of convex lens through each self-corresponding ellipsoidal mirror reflection.
Have radiator on the aluminium base.
Among the present invention,, can make the interior layout of lamp more reasonable because the led light source volume is little; Adopt led light source can make that temperature is reduced to below 60 ℃ in the lamp, significantly reduce the possibility that water smoke produces, can prolong each parts service life of lamp; Through the design of semi-section, when reducing volume, made full use of light source light-emitting efficiency, reduce the light waste, can economize on electricity 70%.

Fig. 2 is the structural representation of the embodiment of the invention 2.
Fig. 3 is the structural representation of the embodiment of the invention 3.
The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of four ellipsoid LED projection dazzle lights comprise support 2; The support front end is equipped with convex lens 1; The rear portion is provided with the aluminium base 5 that has radiator in the support 2, and aluminium base 5 upper and lower two sides are equipped with two LED lamps 3 respectively, and the light emission direction of adjacent LED lamp is opposite; Be equipped with ellipsoidal mirror 4 on the rack inner wall of each LED lamp 3 correspondence, be respectively equipped with two ellipsoidal mirrors 4 in the above and below of aluminium base 5.The light that four LED lamps send converges at the intersection point of convex lens through each self-corresponding ellipsoidal mirror reflection.
The LED lamp is high-power white light source, and ellipsoidal mirror can reflect the light that the LED lamp sends with light and redistribute.Operation principle: behind the power connection, the light that the LED lamp sends blocks a part of light through shadow shield after reflecting through ellipsoidal mirror, and "cut-off"line penetrates through forming clearly behind the convex lens again.
Embodiment 2: as shown in Figure 2, a kind of four ellipsoid LED projection automobile dipped headlights comprise support 6, and the support front end is equipped with convex lens 1, and shadow shield 6 is equipped with at support 2 middle parts, and the rear portion is provided with the aluminium base 5 that has radiator in the support 2.
Other structures are with embodiment 1.
Embodiment 3: as shown in Figure 3; A kind of color LED projection shot-light; Aluminium base 5 upper and lower two sides are equipped with two LED lamps respectively, are followed successively by red LED lamp 3a, green LED lamp 3b, blue led lamp 3c, white led lamps 3d from front to back, and the light emission direction of adjacent LED lamp is opposite; The ellipsoidal mirror 4a, 4b, 4c, the 4d that are provided with on red LED lamp 3a, green LED lamp 3b, blue led lamp 3c, the corresponding respectively rack inner wall of white led lamps 3d.Through the light and shade colour mixture of four LED modules with different colors, produce the light of various different colours.
Other structures are with embodiment 1.
