The damage to led drivers for not considered the VF range of led lamps? Apr 19 ,2021

The load side of the LED lamp is generally composed of a number of LED strings in parallel, and its working voltage Vo=Vf*Ns, where Ns represents the number of LEDs connected in series. The Vf of the LED changes with temperature. Generally, at a constant current, the Vf becomes lower at high tempera...

The principle of 0/1-10v dimming? Apr 16 ,2021

How does the 0-10V dimmer control the 0-10V dimming power supply to achieve dimming? The engineer design the power supply with a control chip which is connected to 0-10V or 1-10V dimmer, the output current of the power supply can be changed by changing the voltage of 0/1-10V to control the bri...

Is there a relationship between ripple and stroboscopic? Or what factors cause the flicker in general? Apr 14 ,2021

Ripple is the main cause of stroboscopic. The larger the wave, the larger the stroboscopic and the wave shape. Regarding to the ripple, the dimming power supply that adjusts the PWM output is also defined as a strobe on the camera equipment, which is in the shape of a regular bar. When the PWM ...

Should we select the 24V or 48V led power supply? Apr 12 ,2021

There are a few difference in dc led power supplies with 24v and 48v both voltages. 24Vdc: There are more power supplies available in 24V than 48V, this will makes them more compatible with phase cut dimming dimmers and 0/1-10v dimming, RF handhold dimmers and phone app dimming. That is the reason f...

Do you have 500mA multiple output current dimmable led driver? Apr 09 ,2021

Yes, we have multiple output current dimmable led driver with triac, 0-10V, DALI dimming. They are all have CE ROHS approval currently, will have UL and FCC certificate in the following days. Well, all of them have DIP Adjustment which you can have one led driver with many output current selection, ...

Do all LED lights need a driver? Apr 07 ,2021

Yes, all LED lights need drivers for protection. 1. Since LED is a characteristic-sensitive semiconductor device,has negative temperature characteristics, LED driving power (also called driver) is to protect it in a stable working state during application. 2. The requirements of LED devices for driv...
