Eight tips to teach you how to distinguish between leds lights and solar energy

1, look at the overall the power factor of lamps and lanterns: low power factor, the use of drive power supply, circuit design is not good, will greatly reduce the service life of lamps and lanterns, low power factor, again use the lamps and lanterns of good lights, life is not long. 2, see the lamps and lanterns,

1, the power factor of the whole lamp. : low power factor indicates that the drive power and circuit design used improperly, it will greatly reduce the service life of lamps and lanterns. Low power factor will not use the best lamp bead to extend the service life of the lamp.

2. See & other lamps and lanterns of the cooling conditions - — Materials, structure and status; : the LED heat dissipation is also very important. For the same power factor of the light and the same quality of light, if the cooling condition is bad, lights, can work under high temperature, light attenuation will be very big, the life of the lamp will be shortened.

3, see & other lamp bead quality throughout & : lamp bead quality depends on the chip quality and packaging technology.

4. Look at the lights use the driver power supply. The service life of power more than other part of the lamp. The service life of power influence the overall service life of the lamp. Theoretical service life of the lamp bead between 50000 and 100000 hours, and the service life of power supply in 0. Between 2 to 30000 hours. Power supply design and material selection will determine the service life of power supply.

5. See lighting: lighting effect is higher, the higher brightness, the same lighting brightness, less power consumption, energy saving more.

6, the power efficiency, power efficiency, the higher the better, higher, shows that the lower the power consumption of power itself, the greater the power output.

7, is to see whether it meet safety standards? China led lamps and lanterns of safety standards have been issued, please choose according to the safety standards set by the state led lamps and lanterns.

8, is whether the work fine.
