High-efficiency heat-dissipating all-weather headlights

The present invention relates to a vehicle lamp, and more particularly to an efficient heat-dissipating all-weather headlight lamp which has better heat dissipation efficiency and can be used for daytime lighting and can be used all day.

In 1898, the Columbia electric car produced in the United States was equipped with front and rear lights, making it the world's first car lighting model. However, the front and rear lights were simply placed in front and rear of the car. The lighting range or angle cannot be adjusted, which makes it easy for the passing vehicles and pedestrians to feel glare and affect the driving safety. Therefore, when the electric vehicle develops to the later stage, the manufacturer adds a vertical height adjuster to each lighting to make each lighting The lights can be adjusted to the height of the lighting, so that the height can be lowered to avoid direct traffic to the vehicle or pedestrian eyes. When the lighting range is wider, the vertical height of the front and rear lights can be increased separately, but the vertical height adjuster at that time It is a fixture structure that needs to be manually adjusted. Therefore, the driver must get off the vehicle to move the fixture structure when adjusting the vertical height. This is really inconvenient. Therefore, in 1925, OSRAM GmbH developed and began to produce double-filament lighting bulbs. The emitted light is affected by the difference in the relative positions of the two sets of filaments on the reflector Angle, thereby changing the effective illumination range distance, the driver can switch off the next group of two filaments through the electrically controlled switch to achieve the object distance and near facilitate lighting needs.

Please refer to FIG. 6 , which is a common near-far distance lamp of the prior art, which has a cup-shaped reflector 81 , a heat-dissipating lamp holder 82 , a control circuit 83 , a close-up lamp 84 , a remote lamp 85 , and a transparent cover 86, wherein the cup-shaped reflector 81 has a convex surface and a concave surface, one side of the heat dissipation lamp holder 82 is in thermal contact with the convex surface of the cup-shaped reflector 81, and the other side is in thermal contact with the control circuit 83. The proximity lamp 84 and the distance lamp 85 are respectively disposed on the concave surface of the cup-shaped reflector 81, and are electrically connected to the control circuit 83; the proximity lamp 84 is disposed above the distance lamp 85. After the light emitted by the cup-shaped reflector 81 is reflected, a beam obliquely directed to the horizontal direction can be formed to achieve the effect of close-range illumination; the distance lamp 85 is placed at the focus of the concave surface to emit light After the reflection of the cup-shaped reflector 81, a light beam that is parallel to the horizontal line can be formed, and the effect of the remote illumination is achieved. The foregoing is an electronically controlled switching of the two sets of filaments to facilitate switching between the remote and the close-range illumination. The purpose of the demand.

However, the proximity lamp 84 and the distance lamp 85 are disposed on the concave surface of the cup-shaped reflector 81, and the heat-dissipating lamp holder 82 does not have a fast heat transfer connection, so that the proximity lamp 84 and the distance The heat energy emitted by the lamp 85 when it is illuminated can only be transmitted by the slow radiant heat diffusion method and escaped from the far and close distance lamp, and the heat energy can not be efficiently absorbed and transmitted to the heat dissipation lamp holder 82, and Through the heat-dissipating lamp holder 82, the heat energy is dissipated in the air, and the long-term accumulation of high heat will affect the service life of the lamp; and the aforementioned lamp has no daytime lighting function, especially the EU has imposed mandatory production in the region in 2008. Vehicles must be equipped with daytime lighting, making daytime lighting a future trend. If you want to install the above-mentioned far and close distance lights on the vehicle, you need to add additional space to the car body position other than the far and close distance lights.
