LED dimming internal and external power supply points are two kinds of power supply built-in LED dimming power supply unit, it will replace the original LED fluorescent dimming remove power and remove ballast and starter, let 220V communicate directly added to the mains power two LED dimming can be.
External power supply LED dimming is usually equipped with a special lighthouse, you can replace the original use of. LED dimming power saving up to 80%, more than 10 times the normal life of the lamp, and almost maintenance-free, there should always replace the lamp, ballast, starter questions, about six months down the cost savings you can exchange for capital.
When the power supply voltage is low, LED brightness dimmed, the power supply voltage is high, LED brightness becomes brighter. Of course, resistance, capacitance method buck LED driver biggest advantage is low cost. Some manufacturers to decrease the cost of goods, the choice of the constant voltage drive LED, the same brings uneven brightness of each LED light mass production, LED can not work in the best condition and a series.
About LED dimming technology are the following: linear dimming, PWM (pulse width modulation) dimming, SCR dimming, segmented and remote control dimmer switch dimmer. Future, LED dimming technology towards low-cost, easy to operate the direction of development, not the traditional SCR dimmers installed in Asia and other markets, based on a wall switch or remote control dimmer, intelligent lighting control system approach is the mainstream market.
Environment-friendly semiconductor light source, the light is soft, pure spectrum, using LED dimming power in favor of the workers maintain eyesight and physical health, feeling the cool 6000K cold light source gives visual help gather energy, progressive power .
