Several different types of headlamp designs
Headlamp type based on headlamp housing
Headlamp housing
The headlamp housing, in short, is the case that holds the headlamp bulb. The headlamp casing is different in all cars. The installation of the bulb and the position of the bulb will vary.
1. Reflecting lights
Reflective headlights are the standard headlights that appear in all vehicles, and until 1985, these were still the most common type of headlights. The bulb in the reverse-head lamp is housed in a bowl-shaped box with mirrors that reflect light onto the road
These headlights found in older cars have fixed housing. This means that if the bulb burns out, the bulb cannot be replaced and the entire headlight case must be replaced. These reflective lights are also called sealed beam headlights. In sealed beam headlamps, there is a lens in front of the headlamps to determine the shape of the beam produced by them.
However, newer reflector headlights have mirrors inside the housing instead of lenses. These mirrors are used to guide the beam of light. Through this technology improvement, there is no need for a sealed headlamp housing and bulb. It also means bulbs can be easily replaced when they burn out.
The advantages of reflecting lights
Reflective headlights are cheap.
These headlights are smaller in size and therefore take up less vehicle space.
2. Projector headlight
As headlight industry technology advances, headlights are getting better and better. The projection headlamp is a new type of headlamp. In the 1980s today, the projector headlamp has become quite common, and most new models of cars are equipped with the generation that was first used in luxury cars. However, with this type of headlamp.
Projection headlamps are very similar to reflective lens lamps in terms of assembly. These headlamps also include a light bulb that is enclosed in a steel housing with a mirror. These mirrors act like reflectors, acting as mirrors. The only difference is that the projector headlamp has a lens that works like a magnifying glass. It increases the brightness of the beam and, as a result, the projector's headlights produce better illumination.
To ensure that the beam produced by the projector headlamp is angled correctly, they provide a cutoff screen. The projector headlight has a very sharp cut-off frequency due to the presence of this cut-off shield.
