High-beam and low-beam integrated LED type vehicle lamp

Abstract

The invention discloses a high beam and low beam integrated vehicle lamp. The vehicle lamp comprises a shell, and a reflecting mirror, an LED light source and a lens which are sequentially arranged inthe shell. The light source comprises a low-beam light source and a high-beam light source, the reflecting mirror comprises a low-beam reflecting mirror and a high-beam reflecting mirror, a light blocking piece is arranged between the low-beam light source and the lens, and light emitted by the low-beam light source passes through the low-beam reflecting mirror, then is converged on the light blocking piece and then is emitted out through the lens to form a low-beam light type; the high-beam light source is arranged at the focus of the high-beam reflecting mirror, and light emitted by the high-beam light source passes through the high-beam reflecting mirror and then is emitted out through the lens to form a high-beam light type. The vehicle lamp is simple in structure, structures such asa light type switching movable device and a cooling fan are not needed, the complexity of the device is greatly reduced, the cost of the device is reduced, meanwhile, the light stability is high during light type switching, and the lighting effect is good.

Description

technical field [0001] The invention relates to a vehicle lighting technology, in particular to an LED vehicle lamp with simple structure integrating far and near light. Background technique [0002] There are four types of lens groups commonly used in existing automobiles: 1. Halogen bulb lens group; 2. Xenon bulb lens group; 3. LED light source lens group; 4. Laser light source lens group. The light intensity and light color of the halogen bulb are the lowest in the lens group. The xenon lamp lens group needs a high-voltage ballast, and the high-voltage wire harness needs to be specially protected, and the cost is relatively high. The laser lens group has complex light source technology and the highest cost. Used in luxury cars. Therefore, the LED light source lens group will gradually occupy the main market, especially the far and near light integrated LED car lamp is a commonly used accessory for mid-to-high-end models. With the improvement of LED technology and the req...

AI Technical Summary

Problems solved by technology

The light intensity and light color of the halogen bulb are the lowest in the lens group. The xenon lamp lens group needs a high-voltage ballast, and the high-voltage wire harness needs to be specially protected, and the cost is high; the laser lens group has complex light source technology and the highest cost. luxury car use

Therefore, the LED light source lens group will gradually occupy the main market, especially the far and near light integrated LED car lamp is a commonly used accessory for mid-to-high-end models. With the improvement of LED technology and the requirement of energy saving, it will be widely used in future automotive lighting fixtures , such as the utility model patent with the authorized announcement number CN207688022U, which discloses a far and near beam integrated car lamp, which uses an LED light source as the light source for the far and near beam light, which has low cost and good lighting effect, but the structure needs to be equipped with light blocking structure to realize the switching of light types, the structure is relatively complex, and the stability is poor; at the same time, due to the high temperature of the LED light source, it needs to be equipped with a fan for cooling, which further increases the complexity of the lens group product and reduces the reliability and stability.
