How to choose car LED RV light?

author: DAMAVO ®

Automotive LEDs are equivalent to the eyes of cars, which are not only related to the appearance of the car, but also related to night driving and safe driving in bad weather. As the current development trend of automotive lighting and the "fashion darling" of car lights, LED RV lights occupy an increasingly important proportion in both the original car market 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 lamp refers to the LED (light emitting diode) as the light source of the lamp, the development of which is directly related to the development of LED light source. Semiconductor electroluminescence phenomenon was discovered as early as 1907, but due to the weak light, mass production is difficult and costly. It wasn't until the early 1990s that the invention of high-brightness LEDs paved the way for led lighting in the technology and mass production of automotive luminaires.

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

  • Step 1: Look at the color temperature

Color Temperature: Used to define the physical quantity of the color of the light source in illumination optics. It refers to the color change perceived by the human eye under the different energies of light waves, referring 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 penetration;

  • 400 K white band yellow, brightness penetration balanced;

  • 5000K light is all white, which is the highest color temperature of the European standard;

  • 6000K light is all white, slightly blue;

  • 7000K white is significantly bluish;

  • Blue light 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 startup performance:                                                                                                                                
LED lights have two characteristics: First, the higher the temperature, the easier it is to start; The other is that the lights do not blink 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.
  • Step 5: Look at the appearance of the LED tube:                                                                                                                  
From the lamp's point of view, many lights can be put together for comparison. Most of the luminaires with good shape and size consistency are machine bending and molding, and most of them are mass production products. Good product consistency, easy quality assurance, good interchangeability during maintenance. Of course, there can be no signs of cracks, loosening, or the interface being pried over. When installing and disassembling, the lamp head cannot be loosened and cannot be moved less. The plastic shell of the lamp must be selected as a flame retardant type of engineering plastic. Ordinary plastics are easily deformable and flammable, and are prohibited from being used in the production of energy-saving lamps. On the face of it, we can simply distinguish between them. The latter surface is smooth and shiny,
