What is TC point on led power supply?

The TC temperature of the power supply is -- the surface temperature of the power supply at the position directly above the transformer when the power supply rises to a stable state. The transformer is the most prone part of the power supply. To measure the temperature of the TC point, it is necessary to know how much the temperature reaches when the power supply is stable. The TC point is above t...

Why do LED drivers fail?

We rarely see high-quality led driver power supply fail due to manufacturing failures. Because in most cases, the failure of the led driver is caused by installation problems or some environmental factors. Recently, a customer contacted us who has been using SMARTS led driver for many years without any problems, but immediately experienced two failures when installing a new LED light. Th...

How to choose right LED driver?

An LED driver converts AC power to DC power, they come in many wattages and the matching led drivers will optimize your lightings performance and lifetime. Drivers also are available with non-dimming led drivers, or dimming led drivers, come in constant current and in constant voltage working mode, how to choose the right one, depending on the type of LED application. Constant Current LED Driver a...

The function of LED drivers for LEDs

LEDs are semiconductor devices that emit light when an electrical current goes through semiconductor materials. In order to make LEDs to operate at their best they need the help of LED drivers to provide with reliability, better efficiency, and longer warranty. LED drivers are electrical devices that protect damage to LEDs by regulating the forward volt...

How to Connect Triac Dimmable LED Driver

Triac dimmable driver are popular selling in the market, but how to connect triac dimmable led driver? Before that, you should make sure you have matched “dimmable” LED lights. And then find out if you have an LED compatible dimmer and led driver triac. If all those things are prepared, the most usually connection way for triac dimmable constant voltage LED driver is as below. (see pictu...

What is the purpose of an LED driver?

The 100-277VAC input voltage is the most usually used Household voltage. The led power supply driver transformer will change the input AC voltage into the lower DC voltage to make it match with operating voltage of the LED lights have. It will caused flickering or flashing issues if the led lamp driver used is not match with what the LED Lighting connection needed. Power supply driver also protect...

What is the Difference Between Constant Current and Constant Voltage LED Drivers?

There have two kinds of LED Drivers are most usually used for LED Lighting applications, constant voltage led driver circuit and constant current led driver circuit. Constant voltage is the most usually used type of driver which require a constant and steady DC voltage. Constant voltage LED driver 24v 12v are required for most of the LED design. So...

What is triac dimmer?

triac led dimmer have quickly become a important of many lighting applications and installations. The dimmer allows you to set the intensity of the light and save the output energy. This energy saving effect is considerable when used with LED light sources. Phase-cut dimmers are the most common dimming control and are commonly referred to as triac dimmer. With the development of technology, t...
