Description

Vehicle light assembly with far and near lights

The present invention relates to a vehicle lamp assembly, and in particular to a vehicle lamp that can produce both high light and low light effects.

Please refer to China's invention patent case for high and low light lens car lights No. TW I776531. The high and low light lens car lights in this case include a lamp holder, a front light source, a horizontal mask, a rear light source and a lamp cover. Among them: the lamp holder is It is composed of a first lampshade and a second lampshade located above and below respectively. A reflective reflector cup and a projective reflector cup are provided at the front and rear positions above the first lampshade. The reflective reflector cup and the projective reflector cup are They are connected by a V-shaped joint part. The joint part has a reflective surface connected to the rear end of the reflective reflector cup. The front light source is installed in the second lampshade below the reflective reflector cup, so that the front light source illuminates the rear and upper parts. After the first light is directly reflected by the reflective surface and the reflective cup, it is emitted from the transparent part of the high light above the lamp cover that is closed at the front end of the heat dissipation lamp holder to form a long light with a longer irradiation distance. Inside the second lamp cover A projection channel is formed in the front. When the front light source, horizontal mask and rear light source are installed inside the second lampshade in sequence from front to back, the carrier plate and horizontal mask used to provide the front light source can be exactly blocked in the projection channel. Above, through the formation of the first notch at the rear end of the carrier plate and the second notch at the front end of the horizontal mask, the second light rays irradiated upward by the rear light source can be reflected by the projection reflective cup and pass through the first notch and the second notch. After being forced into the projection channel between the two gaps, it is then projected forward and emitted from the low light transmitting part under the lamp cover. The diffusion effect produced by the low light transmitting part forms a low light with a short irradiation distance. .

However, the lamp has the following deficiencies in actual implementation:

1. Since the reflective reflector cup and the projective reflector cup are located at the front and rear of the first lampshade, and the reflective reflector cup and the projective reflector cup are connected by a V-shaped joint, the overall car light The length is too long, which is not conducive to the design of the car lights.

2. The front light source is installed on a carrier plate, and the carrier plate is assembled and fixed on the second lampshade on both sides. This structural design will make it difficult for the heat energy generated by the front light source to dissipate through the second lampshade, affecting the front light source. service life.
