Consumers purchase LED lighting in the Division, it is necessary to know some common parameters of LED lighting products, such as intensity, wavelength, color temperature, to distinguish between good and bad code. Small series for broad consumer explanation below commonly used parameters of LED lighting products, tell you how to buy LED lighting products.
LED lamp brightness includes:
Brightness l: light in a particular direction of luminous flux per unit solid angle per unit area. Setting: off (CD/square meters).
Luminous flux φ: luminous body announced that the sum of the amount of light per second. Unit: lumen (Lm), luminous glow, emitting more lumen larger.
: Larger lumen luminous flux more, higher brightness of the lamp.
Common LED wavelength and color together. No LED light color meter manufacturers is difficult to produce color products.
3, color temperature
The color temperature is to identify the units of measurement of light color, with k values indicated. Yellow light that is "3300k", white light that is "5300k", a kind of intermediate colors "3300k-5300k". Customers according to their favorite, environmental effect and required the construction of lights and atmosphere appropriate to the color temperature of the light source.
4, leakage current
LED is a one-way electric light, if there is a reverse current, it is called leakage, leakage current of LED, days are short.
5, antistatic abilities
Antistatic abilities are strong LED, days are long, so offer. Antistatic than 700V LED general skills used in LED lighting (lighting decoration).
