High-power LED light to purchase skills, high-power LED market price of vicious competition, a large number of substandard products listed has violated the high-power led energy-saving, long life, environmental protection, such as real value, how to distinguish the pros and cons of high-power LED lamps, should start from the following:
1. See the overall “China outdoor led flood light fixtures power factor” : Low power factor, indicating the use of driving power, circuit design is not good, will greatly reduce the life of lamps and lanterns, low power factor, the use of a good lamp bead life will not be long.
2. See “Lighting cooling conditions-materials, structure”: High-power lighting cooling is also very important, the same power factor lamps and the same quality of the lamp bead, if the heat dissipation conditions are not good, light bead in the high-temperature work, light failure will be very large, lamp life will be reduced.
3. See “Light Bead Quality“: The quality of light bead depends on the chip quality and packaging technology.
4. look at the power supply used by the luminaire, the service life of the power supply is relative to other parts of the lamp, life is much shorter, the life of the power supply affects the whole life of the lamp, the theory life of the Light bead.
5.1 million hours, and the life of the power supply is 0.2-30,000 hours, the power supply’s design and material selection will determine the 5 See light effect: the same lamp bead power, the higher the light efficiency, the higher the brightness, the same illumination brightness, power consumption is smaller, the more energy-saving.
6. Look at the power efficiency, the higher the power efficiency, the higher the power supply itself, the smaller the power consumption, the larger the output.
7. Is it to see if the safety standards are met? China’s high-power LED lighting safety standards have been introduced, according to the national security standards to choose high-power LED lamps.
8 is to see whether the workmanship is fine. A good quality high-power LED lamps, in addition to the above mentioned several major aspects, but also according to the different use of the environment, there are different technical requirements, such as moisture-proof, dustproof, magnetic, lightning and so on.
