If you’re looking for a lighting solution that will adapt to your own needs, then dimmable LED panel lights are a great option. They offer a range of brightness options, ranging from 10% to 100%. Different from ordinary lamp, dimming LED panel light is suitable for wider applications as well as it also play a great role in energy-saving and emission reduction.
What is dimming led panel light?
Dimming LED panel light is a type of panel light with good illuminance uniformity, higher CRI, uniform and soft light. Dimming led panel light means the brightness of the light can be adjusted. Generally speaking, there are three kinds of dimming methods of dimming led panel light.
Types of dimming LED panel lights
1. LED 0/1-10V dimming
0-10V dimming, also called 0-10V signal dimming, is an analog dimming method. It controls the output current of the power supply by changing the voltage of 0-10V to achieve dimming. It is brightest when it is 10V, and it is off when it is 0V. For 1-10V dimming, when the resistance dimmer is adjusted to a minimum of 1V, the output current is 10%, and if the output current is 100% at 10V, the brightness will also be 100%. 1-10V does not have the function of a switch, and the lights cannot be adjusted to the lowest closing function, while 0-10V has the function of a switch.
2. LED SCR dimming
SCR dimming is currently the most widely used dimming method. It is a physical property of dimming. The SCR dimmer has the advantages of high adjustment accuracy, high efficiency, small size, light weight, and easy to operate from a distance, and is dominant in the market. The advantages of SCR dimming are high working efficiency, stable performance and low dimming cost.
PWM dimming is also known as digital dimming. This method changes the on-time of the forward current by turning the LED on and off with a PWM wave to achieve the effect of brightness adjustment. PWM is a very effective technique for controlling analog circuits using the digital output of a microprocessor. In this way, the cost and power consumption of the system can be greatly reduced. PWM adjusts the brightness by adjusting the time ratio of light and dark.
Advantages of dimming led panel lights
1.energy saving & environmental protection
As an environmentally friendly energy-saving light, LED dimming panel light has the same effect as other lamps in lighting, there is a special performance that the incandescent lamp does not have – dimmable function, different from ordinary lamp, dimming LED panel light is suitable for wider applications as well as it also plays a great role in energy-saving and emission reduction.
2016, the country’s total electricity consumption reached 5.9 trillion kw.h, of which only lighting electricity has about 600 billion kw.h, if we use the LED panel light or other LED lights which consuming 1/3 less energy to replace the tradition lamp, the energy-saving effect will be obvious, thus LED panel light with dimming function is more popular among consumers.
The dimming technology reduce the output power, which significantly improves the working environment of LED panel light, extend lifespan of light and improve its reliability. The key factor affecting the reliability of LED panel lights is temperature.
Whether it is LED power supply or LED chip, the higher ambient temperature is, the less lifespan and reliability will be. LED power supply service life is up to 320,000 hours in 25 ℃ ambient temperature, but it will be sharply down to only 35,000 hours in 60 ℃ ambient temperature.
With higher temperature, the LED chip’s light failure rate is also significantly increased. LED light failure is closely related to its junction temperature that is temperature of the semiconductor PN junction, higher junction temperature, LED light source will sooner occur the light failure, which means shorter lifespan of LED light.
If the junction temperature is 105 ℃, the LED light will just work 10,000 hours as well as brightness down to 70%; the junction temperature is 95 ℃, the LED light can work 20,000 hours; the junction temperature is 75 ℃, the LED light will serve 50,000 hours; while the junction temperature is 65 ℃, the LED light will serve as long as 90,000 hours. In other words, the key of extending LED light lifespan is to reduce the junction temperature.
Adopt dimming technology, reducing output power, the LED power supply will decline its own power consumption, and the shell temperature will decline at the same time. When the ambient temperature is 25 ℃ and at full load, the shell temperature is 50 ℃, but when you use dimming technology to control output to only 50% load, the shell temperature will drop to 40 ℃, service life will be doubled, reliability can be increased by 25% 40%.
Find best dimmable LED panel light supplier
There are numerous benefits of buying dimmable LED panel lights. Not only can they be adjusted to the right brightness, but they will also save you money on your electricity bills. Dimmable LED panels are ideal for areas where light levels need to be lower at night or high during the day. Find best dimmable LED panel light supplier by following these simple tips. Read on to discover the many advantages of dimmable LED panels.
Before you buy your new LED panel lights, check their compatibility with existing lighting fixtures. Some can be attached to ceiling surfaces, while others can be mounted in recessed, surface, or suspended light fixtures.
Make sure that the product comes with the necessary mounting equipment to fit into your existing lighting fixtures. Otherwise, you’ll need to buy it separately.
You should also check whether it comes with a warranty. The manufacturer may offer different warranty terms depending on the type of mounting system you choose.
With rapid development of dimming technology, LED lighting dimming system will be brought into a new field, which will help to popularize and promote the green and energy-saving LED panel lighting.
