Is becoming more and more popular and widely used. The quality of LED light source directly affects the use effect. How to judge the advantages and disadvantages of solar led street lamps?

1. Check the brightness of the lamp.

Generally, the brightness of high-power LED will be much higher than that of low-power LED, and the price will be much more expensive.

2. Antistatic ability of observation lamp.

The antistatic LED has a long service life. Generally, LED with anti-static voltage higher than 700V can be used for LED lighting.

3. Understand the leakage current of lamps.

LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LED with high leakage current has short life and relatively low price.

4. Identify the chip of LED lamp.

LED emitter is a chip, and because of its high quality and high price, it usually imports different chips from abroad.

5. Observe the luminous angle of the lamp.

LEDs with different purposes have different luminous angles. According to different needs, it is important to choose the application that is most suitable for your lamp purchase. Therefore, you need to know the site of the purchased application.

6. Know the wavelength of the lamp.

LEDs with the same wavelength have the same color, and the relative price will be higher. We must realize that there is no LED distributor

It is difficult for manufacturers of color separation instruments to produce solid color products, so they must choose products from manufacturers with good reputation.

7. Understand the colloid of lamps.

The gel of ordinary LED is usually epoxy resin, while the LED with flame retardant and UV resistant functions is more expensive. High quality outdoor LED lighting must be UV resistant and fireproof.

8. Understand the radiator of lamps.

The radiator can see the appearance of the lamp. If the external or internal lamp is made of aluminum, the heating effect of the lamp can be solved, and the service life of the lamp can be better extended. Temperature plays a key role in the service life of LED lamp beads.
