LED dimmer: How does LED dimmer lighting work?

This lighting is used in hotels and theaters to create an atmosphere and create a different atmosphere to please diners and spectators. For conference rooms and lecture halls, lighting can also reduce energy consumption and enhance space functions. Then LED dimmers: How does LED dimmer lighting work?

LED dimmer: How does LED dimmer lighting work?

With the advancement of technology and the increasing popularity of smart lighting, lighting can play a role in many occasions, such as adjusting the brightness of different lights in the home to create a comfortable, quiet, harmonious and warm atmosphere. In the office, soft light can bring a good mood. Less dark light can help you think. More and brighter light makes the atmosphere hotter. Before we introduce smart lighting, one advantage of smart lighting over traditional lighting is lighting control. It can not only play the role of rendering the atmosphere, but also effectively extend the service life of the lamp.

LED light-emitting function: When electrons pass through the chip, negative electrons move to the positively charged ground area and recombine with it. When the electrons and needles disappear, the photons produce a light-emitting function that is different from traditional lighting. Is the P-N flip-chip LED light source, the same can be explained by the power supply voltage parameters are not the same, the internal wiring structure and circuit distribution is not the same, resulting in manufacturers to drive the light source requirements are not the same. Therefore, the mismatch between the control system and the light source device has become a common problem in the industry. At the same time, the diversification of LEDs also poses a higher challenge to the control system. If the control system does not match the lighting equipment, the light may go out or flash, and the LED drive circuit and light source may be damaged. There are five control modes for LED lighting equipment on the market:

1. Stage small cut (FPC) and crystal door.

2. Rear chord phase cutting (RPC),MOS tube lighting.

3.0-10V illumination.

4. Digital addressable lighting interface. Dmx512 (or Dmx) lamp.

5. This cutting-edge lighting device uses a transistor circuit. Starting from AC 0 phase, the input voltage is a cut wave, and the voltage input is only available after the transistor is turned on. The principle is to change the sine waveform by adjusting the communication angle of each wave communication, so that the cutting-edge photographer has the advantages of high adjustment accuracy, high efficiency, small size, light weight, and easy remote control. It dominates the market. Most of the manufacturer's products are this kind of lighting equipment. Tip phase control devices are generally used as switching devices, so silicon lamps are also used.

6. The advantages of using transistor activity in LED lighting are: low lighting cost, compatibility with existing lines, and no need to control lighting along the line after rewiring. The disadvantage is poor dimming performance, which usually results in the dimensionality of the dimming range. The small load required exceeds the rated power of a single or small number of LED lamps. Due to the characteristics of the gate half-controlled switch, it only has the effect of turning on the current and cannot completely cut off the current. Even if it is adjusted to a small level, there is still a weak current passing through. LED micro current luminous characteristics, so that a large number of crystal door color darkening.
