1. LED light source is environmentally friendly

LED is an all-solid-state illuminant, impact-resistant and non-breakable, waste-recyclable, non-polluting, reducing the generation of harmful gases such as sulfur dioxide and nitride, and the generation of greenhouse gases such as carbon dioxide. It can be called "green lighting source."

There are currently three kinds of white LED technology: one is to use the three primary color principle and the three kinds of ultra-high brightness LEDs that can be produced, such as red, green and blue, to be mixed in light ratio of 3:1:6 to form white, two kinds, and use super Highly InGan blue LED, the tube is always added with a little pomegranate-based phosphor, which can produce yellow-green light under blue light excitation, and this yellow-green light can synthesize white light with the exposed blue light. Light LEDs use ultraviolet light-activated trichromatic phosphors or other phosphors to produce white light mixed in multiple colors.

2. LED light source is more energy efficient

Of course, energy saving is the most important reason for us to consider the use of LED. Maybe LED is more expensive than traditional light source, but it takes one year's energy saving to recover the investment of light source, thus obtaining several times of energy saving net closing period in 4-9 years.


Constant current source driving is the best LED driving method. It is driven by constant current source. It does not need to connect current limiting resistors in the output circuit. The current flowing through the LED is not affected by external power supply voltage changes, ambient temperature changes, and discrete LED parameters. The influence is such that the current can be kept constant and the various excellent characteristics of the LED can be fully utilized.

LED constant current power supply is used to supply power to LED lamps. Since the current flowing through the LEDs is automatically detected and controlled during power supply operation, there is no need to worry about excessive current flowing through the LEDs during power-on, and there is no need to worry about load short-circuiting. Bad power supply.
