The vicious competition of LED market prices, the listing of a large number of substandard products has violated the energy saving, long-term Life, environmental protection and other real values, how to distinguish the pros and cons of LED lamps, should start from the following aspects:

1. Look at the overall "power factor of lamps": the power factor is low, indicating the driving power and circuit used If the design is not good, the service life of the lamp will be greatly reduced, the power factor is low, and the life of the lamp with the best lamp beads will not be long.

2. See "Lamp heat dissipation conditions - material, structure": LED lamps heat dissipation is also very important, the same Lamps with power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads work at high temperature, the light decay will be large, and the life of the lamp will be reduced.

3. Look at "Lamp quality": The quality of the lamp depends on the chip quality and packaging technology.

4. Look at the driving power supply used by the lamps. The service life of the power supply is relative to other parts of the lamps. It is much shorter. The life of the power supply affects the overall life of the lamp. The theoretical life of the lamp bead is 50,000-100,000 hours, while the life of the power supply is 0.2-30,000 hours. The design and material selection of the power supply will determine the life of the power supply.

5. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same The lower the power consumption, the more energy saving.

6, look at the power efficiency, the higher the power efficiency, the better, the higher the power consumption of the power supply itself The smaller it is, the greater the output power.

7. Is it in compliance with safety standards? my country's LED lighting safety standards have been introduced, please choose LED lighting according to the national safety standards.

8, is to see if the workmanship is fine.

A good quality LED lamp, in addition to the above-mentioned main aspects, should also be based on different The use environment has different technical requirements, such as moisture-proof, dust-proof, anti-magnetic, anti-lightning and so on.
