What parameters should I pay attention to when selecting LED street lights?
How to choose a good lamp when shopping? Below LED Street Light Supplier for industrial lighting LED lights for your simple explanation!
A light is simply a light! Brightness is a top priority
Brightness is the most concerned topic when users choose LED lights. Brightness is explained from two aspects:
Luminous flux phi: the sum of the amount of light emitted by an emitter per second. Unit: lumen (Lm), indicating the amount of luminescence, the more luminescence the larger the lumen number.
Luminance L: the luminous flux of the emitter in a specific direction per unit solid Angle per unit area. Unit: take off (CD / ㎡).
Users can judge the brightness of LED lights according to the light flux, which is usually marked with the light flux. The higher the flux, the brighter the lamp.
2, the wavelength
It is difficult for LED Street Light manufacturer without LED spectrocolorimeter to produce pure color products. Remember, leds with the same wavelength have the same color.
3, color temperature
Users can choose the appropriate color temperature according to the lighting application environment and homework needs.
And color temperature is the measure unit that identifies light color, express with K value.
White light is "above 5300k", yellow light is "below 3300k", and there is a middle color "4000k-5000k".
4, eakage current
Large leakage current LED, short life.
Leakage: LED is unidirectional conductive luminous body, if there is reverse current.
5, anti-static ability
Strong anti - static LED, long life, and therefore high price. There are a lot of fake and inferior products in the market which do not do well in this field. This is also the fundamental reason why the life expectancy is greatly shortened.
