Eight skills to teach you to distinguish the LED lamps and lanterns
LED the market price fight of vicious competition, a large number of unqualified products listed has violated the LED energy saving, long life, environmental protection, etc. The real value, color LED display wisdom, powerful giant now share how to distinguish the pros and cons of LED lamps and lanterns, from the following several aspects: 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 'cooling condition - material, the structure of lamps and lanterns' : LED lamps and lanterns of heat dissipation is also very important, with the same power factor of lamps and lanterns and the quality of lamp bead, if the cooling condition is bad, lamp bead work under high temperature, the light failure will be very big, lamps and lanterns of life will be reduced.
3, see 'lamp bead quality' : lamp bead quality depends on the chip quality and packaging technology.
4, lamps and lanterns use drive power supply, the service life of power relative to other parts of the lamps and lanterns, shorter life a lot, the service life of power affect the whole life of lamps and lanterns, lamp bead in 5 - the theory of life
100000 hours, and the life of the power supply in 0.
30000 hours, the power supply design and material choice of the service life of decision power.
5, see light efficiency: the same lights, power, light efficiency is higher, the higher brightness, the same lighting brightness, power consumption is smaller, more energy saving.
6, the power efficiency, power efficiency, the higher the better, the higher the power itself, the less power consumption, the greater the power of the output.
7, is to see whether they meet safety standards?
Safety standards has been introduced in China LED lamps and lanterns, please according to the provisions of the state safety standards to choose the LED lamps and lanterns.
8, is whether the work fine.
A good quality LED lamps and lanterns, besides the major aspects mentioned above, but also according to different environment, different technical requirements, such as moisture, dust, antimagnetic, lightning protection, etc.
