Abstract

The utility model discloses an automobile headlight which comprises a headlight shell, a headlight nest arranged inside the headlight shell, a light source arranged on the headlight nest, and a light distribution system. The light distribution system comprises a round convex lens arranged in front of the light source and a round cylindrical lens arranged in front of the convex lens. The cylindrical surfaces of the round cylindrical lens are arranged in the vertical direction. In this way, a round concentrating system is adopted to generate rectangular or elliptical light spots suitable for automobiles, thereby being conducive to arrangement and saving space; and meanwhile, the cylindrical lens has a certain light mixing function, thereby reducing the phenomena of uneven light spot colors and luster and preventing the generation of lens glare.

Description

Car headlamp
Technical field
The utility model relates to a kind of light fixture, particularly a kind of car headlamp.
Background technology
The optical design of car headlamp mainly is Blang's body radius that spot light or similarity light source send to be changed become the asymmetrical beam spot, and the light that briefly will shine automobile top exactly will elongate about hot spot toward pressing down.The optical design of this function that realizes is a lot of at present, for example can outside spot light, use rectangle or oval prefocus cup, but adopt the auto bulb of this structure can produce dazzle on the one hand, on the other hand because prefocus cup can't mixed light, so the uniformity of hot spot is relatively poor, this situation is just more obvious when particularly adopting LED to be light source.In addition, the patent No. is that the patent of ZL200310113810.X has also disclosed a kind of technical scheme that adopts the rectangle collector lens, the defective of this technical scheme is that collector lens is shaped as rectangle, has taken irrational space, makes light fixture produce difficulty on arranging.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of compactness, the uniform car headlamp of hot spot.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of car headlamp comprises light source and light distributing system, and described light distributing system comprises the circular cylindrical lens before being arranged on the preceding bull's-eye of light source and being arranged on convex lens, and the cylinder on the described circular cylinder head lens vertically is provided with.
The beneficial effects of the utility model are, angle of scattering by the next bright body light of pool that earlier spot light is sent of convex lens is dwindled, and then light is dispersed on horizontal direction by cylindrical lens, substantially remain unchanged on the vertical direction, so just can on the direction of illumination of automobile, form one and be suitable for rectangle or the oval-shaped hot spot that automobile uses; Simultaneously, cylindrical lens also has certain mixed light effect, reduces the generation of hot spot color and luster non-uniform phenomenon and control dazzle; In addition, condenser system is circular, helps arranging and saving the space.
Preferably, a plurality of parallel cylinders on described cylindrical lens comprises base plate and is arranged on base plate.
Preferably, a lamp plate is set also in the described lamp socket, the lamp plate front is provided with a plurality of independently light sources and light distributing system, to improve brightness.
Preferably, the described lamp plate back side also is provided with radiating fin.
Preferably, be filled with heat conductive silica gel or silicone grease between described lamp plate and radiating fin.
Preferably, described light source is LED.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further,
With reference to figure 4, Fig. 5 and Fig. 6, the utility model comprises lamp housing 8, be installed in the lamp socket 4 in the lamp housing 8, be installed in light source 1 and light distributing system on the lamp socket 4, described light distributing system comprises the circular cylindrical lens 3 before being arranged on the preceding bull's-eye of light source 2 and being arranged on convex lens 2, and the cylinder 31 on the described cylinder head lens vertically is provided with.
Lamp housing 8 is used to connect automobile body and light source and light distributing system thereof is installed; Lamp socket 4 is a goblet, and the cup body is fixed in the lamp housing, and the cup end is provided with a plurality of light holes 41; One lamp plate 6 is set in the lamp socket 4, the corresponding LED 1 of a plurality of and described light hole is installed on the front of lamp plate 6; A plurality of convex lens 2 are contained in earlier on certain position ring 5 in advance, and locating ring 5 combines with lamp plate 6 and makes a plurality of convex lens 2 overlap respectively to receive on a plurality of LED1; A plurality of parallel cylinder 31 on cylindrical lens 3 comprises base plate 32 and is arranged on base plate 32, before cylindrical lens 3 places convex lens 2, specifically can install on the light hole or on the locating ring, above-mentioned LED1, convex lens 2, cylindrical lens 3 and light hole 41 are on same optical axial.Above-mentioned light source led 1 also can be tengsten lamp or fluorescent lamp, for strengthening the thermolysis of lamp plate 6, radiating fin 7 can also be set at the back side of lamp plate 6, and at lamp plate 6 and 7 of radiating fins thermal grease or silicone grease be set.
With reference to figure 1, Fig. 2 and Fig. 3, penetrate with directional light or small angle of scattering behind light planoconvex lens 2 optically focused that LED1 sends, the angle of angle of scattering can be provided with by the trigonometric function relation according to actual needs, for example when the spot radius that needs 10 meters distant places is 1 meter, passes through the law of tangents tan θ = 1 10 Set the θ value.On the described cylindrical lens 3 cylinder 31 can only be set, also a base plate 32 can be set earlier, a plurality of cylinders 31 are set on base plate 32 again, if a plurality of cylinders 31 are set, then all cylinders 31 should be parallel, and become the vertical direction setting after lamp installation.Like this, the light that shines the vertical direction on the cylinder head lens 3 can not reflect, and the glazed thread X of horizontal direction both sides refraction to the left and right as shown in Figure 2, thereby forms as shown in Figure 3 rectangle or oval-shaped hot spot b.
As shown in Figure 3, when not adding the cylinder lens, by the hot spot behind common luminous intensity distribution cup or the collector lens optically focused is circular hot spot a, such hot spot is not suitable for using on the automobile, because the part luminous energy on its vertical direction slatterns, and the square irradiating width of level may be not enough, this shows that we need elongate the vertical direction compression level direction of hot spot, just realize above-mentioned effect after having adopted cylindrical lens 3, obtained the rectangle or the oval-shaped hot spot b of along continuous straight runs.
