LED Tube Light Features
LED Tube Light Electrical Characteristics:
Current-controlled device, the load characteristic curve similar to the UI of the PN junction, the forward voltage of the small changes will cause a significant change in forward current (index level), the reverse leakage current is very small, there is the reverse breakdown voltage. In actual use, should be selected. LED forward voltage decreases with increasing temperature, with a negative temperature coefficient. LED power consumption, in part into light energy, which is what we need. The rest is converted into heat, so that the junction temperature rise. The heat (power) can be expressed as.
LED Tube Light Optical properties:
LED provides a half-width of the monochromatic light, the semiconductor energy gap decreases with increasing temperature, so its emission peak wavelength with temperature rise and growth, i.e. red shift, the temperature coefficient of +2 ~ 3A /. LED brightness L and the forward current is approximately proportional to:, K is a proportionality factor. Current increases, the brightness is similar increases. Also brightness is the ambient temperature, the ambient temperature is high, the compound reduced efficiency, luminous intensity decreases.
LED Tube Light Thermal Properties:
Low current, LED temperature is not obvious. If the ambient temperature is high, LED's dominant wavelength will redshift, brightness will decline, light uniformity, consistency deteriorated. In particular lattice, the temperature rise on the big screen LED reliability and stability more significant impact. So thermal design is critical.
LED Tube Light Life:
The LED will light attenuation caused by long working hours of aging, especially for high-power LED, the light fades problem worse. In determining LED life time, only to damage to the LED lamp end of life is not enough, should be based on a percentage of the LED light attenuation LED life requirements, such as 35%, so that more meaningful.
LED Tube LightFeatures
LED lamp with high quality, durable, energy-saving as the main features of the projection angle adjustment range, 15W brightness equivalent to an ordinary 40W fluorescent, high temperature, moisture and waterproof, leakproof.
