Detailed Description
The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.
Referring to fig. 1 to 5, the automotive headlamp lighting device according to the present embodiment includes a low beam light source 101, a high beam light source 102, and an integral lens 2. The low beam light source 101 and the high beam light source 102 are both a plurality of LED light sources arranged in a dispersed manner, the low beam light source 101 is 3 chips, and the high beam light source 102 is 5 chips. The light source that the dispersion set up for the heat source is dispersed, more is favorable to the heat dissipation, improves the calorifics performance of distance light unit.
The integral lens 2 is composed of three parts, namely a light focusing part, a low-beam passage part and a lens part 206, wherein the light focusing part is composed of 12 light focusing cups which are uniformly distributed, a low-beam light focusing cup queue 201 and a high-beam light focusing cup queue 202 are formed by arranging an upper layer and a lower layer, and two light focusing cups (in this example, 7 light focusing cups matched with the low-beam light sources 101 and 5 light focusing cups matched with the high-beam light sources 102) are arranged in the lower-layer high-beam light focusing cup queue less than in the upper-layer low-beam light focusing cup queue. The low-beam light-gathering cup queue 201 and the high-beam light-gathering cup queue 202 are both connected with an integrated light-emitting plate, and the front end surface of the integrated light-emitting plate is the light-emitting surface of the low-beam light-gathering cup queue and the high-beam light-gathering cup queue 202. The lower half part of the integrated light emitting plate is provided with mounting holes 207 at two sides of the high beam light gathering cup queue. The low-beam light sources 101 are arranged at the optical origin of the condenser cups of the low-beam condenser cup queue 201, and the high-beam light sources 102 are arranged at the optical origin of the condenser cups of the high-beam condenser cup queue 202.
