Can your LOGO put into UL or ETL listed led drivers product label?

Nowadays, with a strong brand awareness and marketing awareness in in the LEDs industry, many customers will choose to OEM production to promote products with own brand. Then, is it still acceptable to put your LOGO to ETL or UL listed led power supply? The answer is yes. Actually, for any labels of ETL and UL listed non dimmable or dimmable led drivers , if only the LOGO needs to be changed to cu...

If your dimming led driver are flicker-free?

LEDs are unable to function without 3 important components: the chipset that emits the light; the led driver that regulates power to the light source; and the radiator of the cooling. LED driver is the vital component of the technology, as we know LED will use the power converted by the led driver to generate light. High efficiency power supplies are good at...

What is the PFC of led driver?

LED drivers provide LED light bulbs with the electricity required for peak performance, the function of an AC to DC LED driver is to step down the input voltage (such as 110VAC or 220VAC) to a lower output voltage to meet the LED’s small voltage needs, normally 12 Vdc and 24vdc.. Power Factor (PF) of a led driver is the relationship between real and apparent power, it means the ratio between the a...

What is the reason why the led light keeps flashing?

LED lights are of the kind that are found in the streets in the big cities that are now feasting and green. At night, the neon lights composed of LED lights will illuminate the entire street. So, what is the reason why the led light keeps flashing? We will introduce to you below. 1.The LED lamp bead does not match the LED driver power supply. Normally, a single 1W lamp bead can withstand current: ...

What happens if you try to dim a non dimmable led driver?

What happens if you try to dim a non dimmable led driver? In our daily life, people always make a non-dimmable LED power supply installed in a circuit with a dimmer switch. At this time, the LED light may work normally. But when the dimmer is fully turned on, the LED light will slowly dim, which may cause unstable dimming, such as flickering or buzzing, which may eventually damage ...

What is the normal working temperature of the aluminum housing power supply?

It is abnormal that the aluminum shell + potting power supply is not hot. When we do a burn-in test in the aging room, it will reach 65 degrees after 2 hours at 200W led power supply, which is very hot. Therefore, the greater the power, the greater the heat generated by the power supply. The silica gel we use hativity, and the heat of the component can be quickly transmitted to the shell. It is no...

How to define whether the power supply has flicker (flicker) or not?

How to define whether the power supply has flicker (flicker) or not? The general led power supply scheme is single-stage, and the ripple is relatively large, there must be stroboscopic, and generally appear wavy in photographic equipment. If it is two-stage PF correction, there is no flicker, such as our 0-10V dimming 100-200W led driver Supplement: Regarding the PWM output dimming power supply, t...

What is a dimmable driver?

What is a dimmable driver? A dimmable driver is a kind of equipment that changes the brightness, color or color temperature of LED light by external signals acting on the dimming module inside the led driver and then changing the output voltage and current. The dimmable electronic led drivers are fundamentally different from ordinary non-dimming LED driver . Compared with ordinary led driver, it c...

Why do 12v LED lights flicker?

Why do 12v LED lights flicker? The 12v LED light application is the best choice to use at home for safety reason. Compared to the 120/240v line voltage, 12vdc electricity flow was not quite strong enough. What is more, 12v LED light is also less energy used. Hence the 12v LED is the most perfect option for cost-effective home lighting. But with technology comes the bad influence, flickering issue ...
