1, the type of vehicle lighting
As automotive exterior lighting, automotive headlamps (head lamp), fog lights, car lights and turn spoke with the curve of the arc light and direction indicator lights are.Car rear brake lights (Stop lamp), direction indicators, rear lights and headlights lighted at the same time, are easy to find in the parking lot traceability reflective properties of the reflectors, reversing lights and the vehicle license plate light and so on. In addition, the recent installation of the car windows, etc. Association of Canada's high brake lights (HMSL). Far away from the rear because, position and high, so in the car when the driver brakes, the signal is easier to find the back of the vehicle, brake status display of the results more desirable.
2, the evolution of automotive lighting lamps before
From the 40's to early 80s, the automotive industry are all-glass sealed headlamp, the lens and mirrors as a single entity, in the middle incandescent heat radiation, a total of 6 kinds of shapes as a unified specification, the product specifications, production process can be greatly simplified, low-cost mass production, so for decades been widely adopted.
3, the structure and function of automotive headlamps
Modern automotive headlamps structure, the basic component is the light source, mirrors and lenses, but also with some small parts in order to adjust the mirror up and down position, adjust the vehicle's air vent and the water temperature gasket.
4, commonly used in automobile headlamps Introduction
Currently used as a suitable vehicle headlamp light sources, mainly halogen H4 and H7, with the main and auxiliary filament structures, the main vehicle for normal driving wire lighting, auxiliary lighting wire for the automotive intersection, when the car relative to the intersection, In order to avoid dazzling other drivers, auxiliary wire around the molybdenum system with a parabolic hair mask, so that light does not exceed above the horizon, while the horizontal direction of injection.
H7 headlamp light distribution to be achieved through the mirror, unlike halogen lamp H4-type molybdenum system as a built light emission mask, but through a complicated surface shape, so that light projected onto the reflective surface of the light, reflected in its re-direction to be strictly controlled. It makes the light emitted headlights reflected light only the composition, and fully maintained in the horizontal direction, so that intersection when two cars, both drivers will not have glare interfere with driving.
