Why do LED power supplies need high efficiency?

The LED power supply is an important component in the LED lighting system. During the use of the LED power supply, a certain amount of heat will be generated according to the quality of the LED power supply design, and heat is the biggest killer of the light decay of the LED power supply. Therefore, if the heat generation is to be small and not obvious, the efficiency must be high. This requires a...

LED power DALI dimming technology

DALI, it is a data transmission protocol, which defines the communication method between the electronic ballast and the device controller. Popular understanding: that is, the communication protocol between DALI dimming driver or DALI dimming power supply and DALI controller in DALI system. It is not a new bus, but it supports open systems. The original goal of designing and applying DALI is to Opt...

How does the LED dimming power supply affect our lives？

Nowadays, with the emergence of demand and technological innovation, lamps with dimming functions have become quite common. And the "heritor" behind this, of course, is the LED dimming power supply. The dimming power supply changes the illuminance and color temperature of the light source by adding a dimming control module inside the power supply and controlling the power supply through an externa...

0-10V dimming principle

The power supply is designed with a control chip. When the 0-10V dimmer is connected, the output current of the power supply is changed through the 0-10V voltage change, and the light is reduced. For example: when the 0-10V dimmer is modulated to 0V, the current drops to 0, and the brightness of the light is turned off. When the 0-10V dimmer is adjusted to a maximum of 10V, the output current will...

What is the role of led dimmer?

The biggest advantage of LED dimmer is energy saving. Although the market situation of lighting dimming is very good in the real use process, its energy-saving effect will be more obvious than that of LED strips. There is a very obvious decrease in work efficiency. At this time, LED dimming will get a very obvious high-efficiency luminous rate. The main reason for this situation is that the forwar...

What is 0-10v led dimmer?

0-10v dimming is a simple lighting control system, which connected to LED fixtures to provide multipurpose lighting solutions and level. At 0 volts, the light will dim to minimum light level, on the contrary, the light will dim to maximum light level at 10 volts. Using a 0-10v led dimmer switch allows we to choose what light level required. 0-10v led dimmer produces light intensities from 10% to 1...

What is Dali?

Dali dimmable is a dedicated lighting control protocol. The dali drivers has the advantages of overall dimming, group dimming, addressing dimming, multi-scene mode setting, simplicity, reliability, excellent function, and flexible extension. The DALI system allows each lamp to have an independent address, so the lamp is upgraded from ordinary lamp to "smart lamp". In fact, the light source in the ...

LED dimmable power supply can save energy and environmental protection

The LED dimmable power supply will release a lot of heat during the working process, causing the die junction temperature to rise rapidly. The higher the LED power, the greater the heating effect. The increase in the temperature of the LED chip will lead to the change of the performance of the light-emitting device and the degradation of the electro-optical conversion efficiency. The waterproof le...
