The answer is very safe, no need.
The principle of illumination of halogen headlights is the same as that of incandescent lights. The tungsten filaments are energized and heated to an incandescent state to emit light.
However, halogen lights are upgraded with incandescent lights, which are halogen elements such as bromine and iodine. The principle is effective to alleviate the loss of tungsten wire at high temperature, which is higher in brightness and longer in life than incandescent lights.
The biggest advantage of halogen headlights is that they are cheap and easy to replace. They are used in low-to-medium models. The color temperature of halogen headlights is warmer, and the penetration in rain, snow, and fog is better.
The disadvantage of halogen headlights is that the brightness is not high and the energy consumption is high.
LED lights can directly convert electricity into light, because of its long life, fast lighting, low energy consumption, etc., often used as daytime running lights and brake lights, have a good effect.
Mostly used in the configuration of high-end models, its performance almost completely exceeds the Xenon headlights.
The only drawback is the higher cost.
The LED headlights are mainly composed of a high-power LED chip module, a power supply driver, and a thermal management system.
Temperature is a key factor in the stability, performance, and longevity of LED headlamps. Thermal management is a necessary means of maintaining a suitable temperature range and uniformity.
Thermal management is simply to allow the chip to operate within a certain temperature range to maintain optimal use to ensure the performance and life of the chip module.
After the LED is energized, approximately 35% of the electrical energy is converted to light energy and the rest is converted to thermal energy.
LED headlights are extremely sensitive to temperature changes. If the LED light is continuously lit at high temperatures, it is prone to low power, reduced life, and the light is turned off.
Therefore, the heat dissipation of the LED headlights determines the life of the LED.
Anyone who knows about LED lights knows that LED lights can be cooled in three ways.
First, Copper braid with heat sink
This type of heat dissipation uses a copper braid in the form of a copper braid to provide heat dissipation. This way is passive cooling.
The heat is quickly conducted through the copper strip. As far as the heat-dissipating material is concerned, the heat dissipation performance of copper is second only to gold and silver, which is better than the heat dissipation of the aluminum material.
When the braid is completely stretched, the best effect can be achieved.
The professional requirements of the installer are high. The installer must be clear that the installation space of the lamp should not be too narrow. The woven belt must be partially unfolded to achieve the best heat dissipation state. If it is not fully deployed, the heat dissipation effect cannot be achieved. Copper is easily oxidized at high temperatures, so nickel plating on the surface of the copper strip greatly reduces its ability to radiate heat.
Second，Aluminum body heat dissipation
This is called integral heat dissipation and also belongs to passive heat dissipation.
The heat generated at the lamp body is conducted to the aluminum seat with the tail exposed to the air through heat conduction, and then the heat is taken away through airflow.
In order to improve the heat dissipation efficiency, some will apply nano-radiation coating on the lamp body to greatly increase the heat dissipation performance.
The invention has the advantages of utilizing the spontaneous heat dissipation of the lamp body, coating nano paint on the outer surface to help dissipate heat and accelerating the heat dissipation speed.
Disadvantages: Generally, the tail shape will be slightly larger in volume. Due to insufficient space during installation, heat cannot be dissipated normally, thus affecting the heat dissipation effect.
Third：Fan cooling
This is an active heat dissipation method, which is equivalent to accelerating the air convection speed. A popular point is that the fan dissipates heat. It adds a fan to the aluminum body to dissipate heat.
This heat dissipation method is that a small fan is additionally arranged at the tail of the LED. When the LED is just lit, the small fan at the tail also works together at the same time. Through the fan, the heat of the aluminum seat is dissipated into the air by means of air convection.
This method is more efficient, and can also enable the LED lamp to dissipate heat well and ensure the service life of the LED.
