How to choose car LED rv light?

Automotive LED is equivalent to the eyes of the car, it is not only related to the appearance of the car, but also closely related to night driving and safe driving in bad weather. As the current development trend of automotive lighting and the "fashion darling" of automotive lamps, LED rv light occupy an increasingly important proportion in both the original car and the modified car market. Compared with halogen lamps, Led lamps have superior quality, better visual experience and safer driving.

What are LED headlights? How did it come about? LED car light refers to the car light that uses LED (light emitting diode) as the light source, and its development is directly related to the development of LED light source. The phenomenon of semiconductor electroluminescence was discovered as early as 1907, but due to the weak light, mass production is difficult and costly. It was not until the early 1990s that the invention of high-brightness LEDs paved the way for LED lighting in automotive lamps both technically and in mass production.

However, although LED lights are good, the car mainly pays attention to how to choose good LED lights. The following points should be noted

 
  • Step 1: Look at the color temperature

Color temperature: a physical quantity used to define the color of a light source in lighting optics. It refers to the color change that the human eye perceives under different energies of light waves, which refers to the color of light. This can be seen directly from the parameter box. The bluer the light color, the higher the color temperature. When the color is red, the color temperature is lower.
  • 3000K yellow light, strong penetrating power;
  • 400 K white with yellow, balanced brightness penetration;
  • 5000K light is completely white, which is the highest color temperature of the European code;
  • 6000K light all white, slightly blue;
  • 7000K white is obviously bluish;
  • Blu-ray above 8000K.

  • Step 2: Look at the heat dissipation.

Heat dissipation: The heat dissipation of the lamp determines the life of the lamp. After the LED is energized, about 35% of the electrical energy is converted into light energy, and the rest is converted into heat energy.
  • Step 3: lamp beads and substrate.

For LED lights, the lamp beads are mainly used to emit light, and the quality of the lamp beads is related to the quality and effect of the entire LED.
  • Step 4: Look at the start-up performance:                                                                                                                                        
LED lights have two characteristics: one is that the higher the temperature, the easier it is to start; the other is that the light will not flash when turned off. In addition, it is worth mentioning that many LED lights are very dark when turned on, which is not good for the life of the bulb. The LED light should have a power supply circuit and a PCB board inside it.
  • Step 5: Look at the appearance of the led tube:                                                                                                                                
From the perspective of the tube, many lights can be put together for comparison. Lamps with good shape and size consistency are mostly formed by machine bending, and most of them are mass-produced products. Product consistency is good, quality is easy to guarantee, and interchangeability is good during maintenance. Of course, there must be no cracks, looseness, and signs that the interface has been pryed. During installation and disassembly, the lamp holder should not be loose and move little. The plastic shell of the lamp must choose the engineering plastic flame retardant type. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. On the surface, we can simply distinguish them. The latter has a smooth and shiny surface, while the former has a texture similar to frosted glass.
