LED flood light manufacturers show you how to demodulate light and how to use it
When LED floodlights are used outdoors, there will often be some dust. If it is not cleaned up, it will affect the brightness of the lighting. Use LED lighting to wipe off the dust, you can wipe it with a clean cloth. It looks the same, but the human eye can still see the dust clearly. The floodlight manufacturer will show you some more.
The repair of LED flood light requires the following points:
1. Regularly check the equipment, our led flood light, during the daily maintenance, if you find any problems with the device, you can repair it in time.
2. The angle of the LED light emitted from the long-term "wind from the eyes to the water", and the appropriate illumination angle of the light needs to be adjusted.
3. In the daily inspection, if there are cracks in the glass on the surface of the luminous body, the luminous body should be removed immediately to avoid injury.
1. Main LED light dimming technology
The following three dimmer methods are to classify the output control of the LED drive current. The control circuit can also be divided into analog control and PWM control usually performed by a microcontroller.
The first dimming is usually called analog dimming mode or linear dimming.
The advantage of this dimming is to linearly increase or decrease the drive current with strong resistance to the control circuit of the LED chip. The disadvantage is that the change of the driving current constantly affects the color temperature of the LED chip, and affects the color temperature of the LED chip.
In the second dimming, since the brightness of the LED chip and the LED driving current have a fixed ratio, the dimming of the LED lamp is realized by adjusting the driving current of the LED.
The third method of dimming is the pulse light modulator (PWM) mode.
The method makes it possible to save the duration while changing the output power, while changing the driving current square, variable pulse width and pulse width adjustment through constant control. Usually, the frequency transfer from 200hz to 10khz, because human eyes maintain vision, people will not feel the movement of light flickering. The advantage of this method is that it can improve the heat dissipation of the LED. The disadvantage is that the excessive driving current has a certain effect on the life of the LED chip.
2. Dimming system and future development
The perfect intelligent control should have manual control, intelligent control, optical control, time control and fault warning functions. It will automatically turn on the light when it gets dark, and the lighting at 12 o'clock in the middle of the night will also be automatically reduced by half. After dawn, the sun will automatically go out;
In special circumstances, people can manually control;
What are the characteristics of SMD floodlights?
1. The light source adopts imported super bright LED integrated chip, professional lighting grade optical lens, pure light color, good color rendering;
2. The high-concentration aviation aluminum material is stretched and formed, and the surface is anodized and hardened, and the surface has high gloss and good gloss. The reflective surface of the lampshade is frosted to make the reflected light more soft and uniform, without glare;
3. Industrial-grade heat dissipation technology, using copper sheet heat conduction and aluminum alloy radiator, through natural air circulation, so that the heat dissipation effect is better, and the excellent heat dissipation technology can ensure the driving power and the light source to last longer;
4. The energy-saving effect is obvious. The high-power LED light source is equipped with imported high-efficiency power supply, which can save more than 80% of energy compared with sodium lamps.
It is suitable for indoor and outdoor lighting places such as construction sites, factory workshops, warehouses, toll stations, stations, large supermarkets, exhibition halls, stadiums, etc.
