How to install LED headlights to focus light?

It is necessary to have the right lens to concentrate the light.

Introduction: The headlights of the car are the headlights of the car, and the headlights are symmetrically installed on both sides of the front end of the vehicle when driving at night in order to identify the lighting fixtures of the front vision. LED is an electroluminescent device that uses a solid-state semiconductor chip as a light-emitting material to directly emit light through the recombination of carriers to cause photon emission.

LED headlights are lighting appliances made by using LED as a light source.

LED headlight advantages:

Advantages of LED headlightsFor automobiles, LED light sources have the following benefits: energy saving, long life, good durability, small size of LED components, compact and easy to arrange and shape design, fast response, low brightness attenuation, etc.

Car LED bulbs can only be focused with a suitable lens. Many people have heard that LED headlights are not focused, so the first idea of carrying lead is to add a lens, because the lens has a strong focusing ability. Not all models have enough empty room to mount the lens, especially if the original option does not have a lens, which can be very cumbersome to install.

Car LED bulbs can only be spotted with a suitable lens, as shown below:

In general, the concentration of LED dipped beams cannot be adjusted. Just the width of the paved road should not be too bright. Light can only be focused when it is far away, and only when it is focused can it be shot far. So, it depends on the design or type of bulb.

The headlight assembly follows the original car, and the internal structure is designed according to the luminous focus of the halogen lamp. If the owner wants to upgrade and replace the halogen bulb of the original car, he must choose an LED headlight that is infinitely close to the light focus of the original car. To do this, the spotlight effect of the headlights will naturally be good, otherwise the light will naturally appear astigmatism after changing the lamp grinding group.

In addition to the influence of the original headlight assembly, some poor quality LED lights on the market will also cause serious astigmatism, which is also the reason why the lights look bright but do not follow the blind Li Orange Road! Poor quality COB light sources produce LEDs with generally improved brightness and are brighter than traditional halogen lamps. The LED, which is assembled from several rough light-emitting chips, has many light-emitting surfaces, but the brightness of the optical center is not concentrated.

Adjust the up, down, left, and right position of the light. First of all, park the car meters away from the wall and turn on the lights. Adjust the position of the light according to its position on the wall.

Adjusting the position of the light is achieved by adjusting the adjustment knob of the corresponding position behind the headlight. The parts that need to be adjusted and the tools used vary from model to model and need to be determined according to the specific model. Before adjusting, hit the lights on the wall and observe if the lights are offset or too high or too low.

The concentrating of LED dipped beams is generally not adjusted. Low light is required to pave widely, not too concentrated. The high beam requires the spotlight, and the spotlight shines far. Therefore, it depends on the design or type of bulb.

The headlight assembly is the original car factory, the structure inside is designed according to the halogen light focus, the owner wants to upgrade the halogen bulb to replace the original car, must choose the original car light focus infinitely close to the LED headlights, to do this, the light focus of the car will naturally be good, otherwise the light will naturally appear scattered after the lamp is changed.

In addition to the influence of the original headlight assembly, the light is not focused, among them, some poor quality LED lights on the market are selected, and serious astigmatism problems will occur, which is the reason why the lights look bright but do not illuminate the road! The brightness of LEDs produced by using poor quality COB light sources is generally improved, and it is brighter than traditional halogen lamps, but the LEDs assembled by several coarse light-emitting chips have many light-emitting surfaces, but the brightness of the light center is not concentrated.

Adjust the position of the light, first park the car at a distance of meters from the wall and turn on the light, and adjust the illumination position of the light according to the position of the light on the wall. Adjusting the position of the light is achieved by adjusting the adjustment knob of the corresponding position behind the headlight. The parts that need to be adjusted and the tools used vary from model to model, depending on the model.

The spotlight of the car can be adjusted by adjusting the position of the light, which is achieved by adjusting the adjustment knob of the corresponding position behind the headlight. Different models need to adjust the parts and tools used, which need to be determined according to the specific model. Before adjusting, hit the lights on the wall and watch if the lights are offset, too high or too low.

The reason why traditional halogen lamps are good at concentrating light is that tungsten filaments light up, and the light comes from a central point, which is usually called "spot light". The point light sources are gathered together to illuminate forward, and are evenly distributed on the road surface through the refraction of the light bowl to ensure that the field of vision ahead is sufficiently bright.

However, many LED headlights have problems such as serious astigmatism and non-condensation due to their own design reasons or various factors during modification. Many people have heard that LED headlights are not focusing, so the first idea is to add a lens because the lens has a strong focusing ability. But in reality, lens-type LED headlights are not suitable for cars.

On the one hand, not all models have enough empty rooms to mount lenses, especially if the original option does not have lenses, which can be very cumbersome to install. Also, remove the lampshade, bumper, etc. Installing lenses will make the headlights less sealed, and it will be difficult to prevent problems such as water ingress and fogging in rainy days.
