The principle of LED dimming power supply?

LED Power Supplysfyh
LED dimming driver power is widely used in lighting fixtures, and its uniqueness is superior to traditional lighting methods. In addition to improving the quality of life, improving the efficiency of the light source, and prolonging the service life of the lamps, the LED dimming driver also uses its unique dimming function to change the color temperature and brightness of the light, and fully realize energy-saving applications as its greatest advantage. The PWM dimming power supply achieves the effect of brightness level by turning the LED on and off with PWM waves to change the on-time of the forward current.…

The challenges faced by landscape lighting led drivers?

LED Power Supplysfyh
Challenge 1: Waterproof problem. In outdoor lighting, LED dimming power supply products need to be done in strict accordance with the IP67 level requirements. The selection of shell materials, design, glue filling, and waterproof parts need to be comprehensive. Challenge 2: Security Issues Safety is the first factor in the application of lighting products. LED controllers and LED dimming power supply products need to comply with national standards and UL certification. The product has short circuit protection, overload protection, over temperature protection and so on. Challenge 3: Flickering and Compatibility Issues If the selected LED controller products and dimming power…

What is the difference between constant current and constant voltage LED drivers?

LED Power Supplysfyh
led driver constant current are designed to specify a range of output voltages and a fixed output current (mA). LEDs rated to operate on constant current drivers require A specified current supply, usually in milliamperes (mA) or amperes (A). Constant current LED drivers have similar power ratings, but have fixed amplifier (a) or milliampere (MA) values for voltage or maximum voltage range. LED equipment shall display its power requirements and rated voltage and current range. If it is only led, current control must be carried out to prevent led thermal runaway. led driver constant voltage usually have fixed rated voltage…

IP67 waterproof rating standard definition

LED Power Supplysfyh
IP rating is an international standard for measuring the dust and water resistance of equipment. In the two-digit IP code, the first digit represents the level of protection against ingress of foreign objects, including dust. The second number indicates the waterproof rating of the device. The IP rating achieved must be certified and independently tested before it can be indicated on the product description. IP6X-completely sealed to prevent the intrusion of foreign objects and dust. IPX7 – Resists immersion in 1 meter deep water for 30 minutes. Under normal circumstances, the IP65 level of LED waterproof power supply can meet…

What conditions must be met for the constant current led driver 110v to support the hot swap of lamps when powered on？

LED Power Supplysfyh
What is hot swap?Hot swappig or Hot plugging) is “hot plugging”, which means that the led driver 110v plugs or unplugs the load lamps at the output end when the input end is powered on. 1. The maximum output voltage of the led driver enclosure box (no-load voltage) = the input voltage of the lamp, if the no-load voltage of the led driver enclosure box is 60V, the input voltage of the lamp is also 60V 2. The output current of the 24 volt 20 watt led driver, the lamp can withstand, such as the output of the  led driver enclosure box  500mA, the current the…

Why do LED lights in the home get dimmer with more use?

LED Power Supplysfyh
It is a very common phenomenon that LED lights become dimmer as they are used. In addition to light decay, the reasons for dimming LED lights are nothing more than the following two points. 1. The drive is damaged LED lamp beads are required to work at low DC voltage (below 20V), but our usual mains is AC high voltage (AC 220V). To turn the mains into the electricity required by the lamp beads, a device is needed, called “LED drive power“. Theoretically speaking, as long as the parameters of the driver match the lamp bead board, the power supply…
