1. Color rendering is an important indicator of LED high bay lights, and the color rendering must be above 80.

2. Mastering the light intensity distribution diagram of LED high bay lights is necessary for the correct use of LED high bay lights. Manufacturers must provide customers with various parameter indicators of LED high bay lights.

3. Thermal resistance directly affects the heat dissipation of LED high bay lights. The lower the thermal resistance, the better the heat dissipation; the higher the thermal resistance, the poorer the heat dissipation, so that the temperature of the device increases, which will affect the wavelength shift of the light. According to experience, when the temperature rises by one degree, the light wavelength must drift 0.2~0.3nm, which will directly affect the luminous quality of the device. Excessive temperature rise also directly affects the service life of LED high bay lights.

4. Whether the color temperature distribution is uniform or not will directly affect the lighting effect; and the color temperature and the color rendering index are related to each other, and the change of the color temperature will cause the change of the color rendering index.

How to judge the quality of LED high bay lights

1. Observe the whole: "The power factor of LED energy-saving lamps, LED high bay lamps": low power factor, indicating that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp, the power factor is low, and the lamp beads are used well The lamp life will not be long.

  2. Look at the quality of the lamp beads: the quality of the lamp beads directly determines the quality of the LED energy-saving lamps and LED high bay lamps, and the quality of the lamp beads is determined by the chip quality and packaging technology.

  3. Look at the heat dissipation system of LED energy-saving lamps and LED high bay lamps. The heat dissipation of LED energy-saving lamps and LED high bay lamps directly affects their quality and service life.

  4. China's LED lighting safety standards have been promulgated, and products must meet the safety standards set by the country.

  5. Look at the driving power used by LED energy-saving lamps and LED high bay lamps. Compared with other parts of the lamp, the service life of the power supply is much shorter. The service life of the power supply affects the overall life of the lamp. The theoretical life of the lamp beads is 5-10 10,000 hours, and the life of the power supply is between 0.2 and 30,000 hours. The design and material selection of the power supply will determine the service life of the power supply.

  6. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.
