There are many lighting fixtures in the market today, and our customers do not know where to buy them. Therefore, before purchasing LED lighting fixtures, we should first understand the relevant parameters of some LED lighting fixtures and how to select reliable high-power LEDs. Gulf lamp manufacturer, please rest assured. Lanyue Optoelectronics will solve your questions!

Precautions for purchasing LED lights:

1. Strong anti-static capability: LED with strong anti-static capability has a long service life. Generally, LEDs with antistatic voltage greater than 700V can be used for LED lighting.

2. Brightness: The price of LED varies with its brightness.

3. Wavelength: LEDs with the same wavelength and color are expensive. It is difficult for manufacturers without LED spectrophotometer to produce solid color products.

4. Luminescence viewpoint: LEDs for different purposes have different luminescence viewpoints. Special luminous angle, higher price. Such as full diffusion angle, the price is higher.

5. LED chip: The emitter of LED is a chip, and the prices of different chips vary greatly. The price of imported chips is higher. 6. Leakage current: LED is unidirectional conductive illuminant. If there is reverse current, it is called leakage. LED with large leakage current has short life and low price.

7. Colloid: Generally, the colloid of LED is epoxy resin. LEDs with UV resistance and flame retardancy are more expensive. High quality outdoor LED lighting shall have UV protection and fire prevention functions.

8. Chip size: the chip size is represented by the side length. The quality of large chip LED is better than that of small chip LED. The price is proportional to the chip size.

9. Radiator: The radiator can see the appearance of the lamp. If the external or internal parts of the bulb are made of aluminum, the thermal effect of the bulb can be solved, so that the life of the bulb can be better extended. Temperature will affect the life of LED lamp beads. Counting plays a vital role.

10. Power supply: According to the plan requirements of different manufacturers, it can be divided into two types: constant current power supply and constant voltage power supply. No matter what kind of power supply, it plays a central role in the service life of the whole lamp. If the bulb fails, it is usually because the power supply has burned out. Now, the new technology chooses AC optical engine to drive constant power lamps with high power factor, low harmonic distortion, overheating and overvoltage.
