Distinguish the advantages and disadvantages of LED lamps

 

The vicious competition in LED market prices, the listing of a large number of unqualified products has violated the real value of LED energy saving, long life and environmental protection. How to distinguish the advantages and disadvantages of LED lamps should start from the following aspects:

 

1. Look at the power factor of the luminaire: the power factor is low, indicating that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the luminaire. The power factor is low, and the life of the lamp using the lamp bead is not long.

 

2, look at the "lighting conditions of the lamps - materials, structure": LED lamps are very important for heat dissipation, the same power factor lamps and the same quality of the lamp beads, if the heat dissipation conditions are not good, the lamp beads work at high temperatures, the light decay will be very large, Lamp life will be reduced.

 

3, look at "light quality": chip quality and packaging technology determine the quality of the lamp.

4. Look at the drive power supply of the luminaire. The service life of the power supply is much shorter than that of other parts of the luminaire. The life of the power supply affects the overall life of the luminaire. The theoretical life of the lamp bead is 50,000-100,000 hours. The life span varies, and the design and material selection of the power supply will determine the life of the power supply.

 

5, look at "light effect": the same lamp power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy-saving.

 

6, look at "power efficiency", the higher the power efficiency, the higher, the higher the power consumption of the power supply itself, the greater the output power.

7. See Is it in compliance with safety standards. The safety standards for LED lamps in different countries have been introduced. Please select LED lamps according to the safety standards stipulated by the state.

 

8, look at "work is fine", good production technology, determine the safety and durability of the lamp in the long-term use.

 

A good quality LED luminaire, in addition to the above-mentioned several main aspects, also has different technical requirements according to different use environments, such as moisture, dust, anti-magnetic, anti-lightning and so on.
