1 Brightness
LED lamp brightness is the subject of most concern to users, brightness can be explained in two ways.
Brightness L: luminous body in a specific direction unit stereo angle unit area of luminous flux. Unit: nits (cd/㎡).
Luminous flux φ: the sum of the amount of light emitted by the luminous body per second. Unit: lumens (Lm), said the number of luminous body luminous, the more luminous lumens, the greater the number.
Usually LED lamps are marked with luminous flux, users can judge the brightness of LED lamps according to the luminous flux. The higher the luminous flux, the higher the brightness of the lamp.
2 Wavelength
LEDs with the same wavelength have the same colour. Without LED spectrophotometer manufacturers are difficult to produce products with pure colours.
3 Colour temperature
Colour temperature is the unit of measurement for marking the colour of light, expressed in K value. Yellow light is “3300k below”, white light is “5300k above”, there is an intermediate colour “3300k-5300k”.
4 Leakage current
LED is a one-way conductive luminous body, if there is a reverse current, it is called leakage, leakage current is large LED, short life.
5 Anti-static ability
The anti-static ability of the LED, long life, and therefore high prices. Many counterfeit products on the market do not do well on this one, which is the expected life of many years, greatly shortened the underlying cause.
The choice of LED luminaires includes appearance, heat dissipation, light distribution, glare and installation. We are not talking about the parameters of the luminaire today, only about the light source: will you really pick a good LED light source? The main parameters of light sources are: current, power, luminous flux, light decay, light colour and colour rendering.
Users should understand that the choice of LED lights can not be like the choice of incandescent lamps just look at the wattage, the wattage of LED lights can no longer accurately interpret the brightness of LED lights, high luminous efficiency of low wattage may also be brighter than the high wattage of LED lights. This is the LED era, only with the right parameters to choose a good quality of industrial lighting with LED lights.
