Epson driver and intelligent switch help smart lighting

Compared to electrical appliances, the number of lighting fixtures far exceeds their myriad orders of magnitude. Therefore, smart lighting is the fastest-moving branch in the dynamic field of smart homes. Under the vigorous promotion of the National Ministry of Housing and Environmental Protection and the Environmental Protection Agency, the proportion of LED light sources used in lighting systems has been increasing. The excellent performance in energy-efficient, precise dimming, and soft start of lighting is far from traditional incandescent and fluorescent lamps. And ordinary energy-saving lamps can be compared. Therefore, in the intelligent lighting system, the smart object is destined to be an increasingly broad LED light source in the market.

The intelligent control of the LED light source is a system engineering, which consists of a switch and a driving power source, and realizes the switching control and adjustment of the LED light source. Due to the high efficiency of the LED lamp, the power is usually very small, so it is easy to generate a constant or flickering phenomenon during the dimming and tinting process. In particular, in the case where there is only a single live line, the dark current supplying the electronic switch can easily fail to turn off. To solve this problem, we must start from the three aspects of the design of smart switches, drive power, and the matching of the two, so as to fully reflect the advantages and characteristics of LED light sources.

Now on the market LED light source adjustment field of intelligent switches with the most varieties, the most complete function of the Epson LED special dimmer switch for various types of dimming methods of pros and cons:

1, dimming smart switch single product dimming: such as BRT-D204, BRT-D205, etc., this type of product uses SCR dimming, specifically for self-driven LED light source, its advantage is that the LED light structure is more simple , More integrated, at the same time in the cost and production efficiency, etc. have a very strong advantage; but the disadvantage is that there is no uniform standard, the LED light manufacturers to their own way, on the market all kinds of light source quality, parameters, and even thousands of miles. Therefore, there is no intelligent dimming switch that can be packaged with the world, and all the LED lights with their own drive circuit to match, the drive circuit is too simple, or the matching degree is poor, it may appear constantly off or flashing phenomenon. In response to this phenomenon, EPRI expands its matching range as much as possible in its LED-based dimming smart switches. In addition to the extensive use of the conventional front-cutting angle technology currently used in LED dimming, it is more innovative and uses back-cut angle technology for this type of application. In the switch, in order to avoid the occurrence of the above problems as much as possible, to the maximum extent to adapt to the vast majority of LED light sources on the market.

2. Dimming smart switch and dedicated driving power are dimmable together: such as BRT-D210, BRT-D261, etc. This kind of product adopts PWM dimming method, due to the high degree of matching of the switch and driving power, and the design is total, the quality is good. Therefore, the technical dilemma of LED dimming is completely solved. Conquered the technical fortress of LED intelligent lighting development in the drive power. The dimming effect is more stable, more efficient, and more energy-saving. This type of intelligent lighting switch is divided into two types: SMC and RFC, depending on the technology used:

A, SMC transmission mode: The use of online transmission technology, LED dimming smart switch will transfer the smart code to the drive power, so as to achieve the purpose of dimming. This method is still on-line transmission, so there may be flickering in the process of dimming, but during the adjustment process, it can provide a very stable lighting source, no flicker, and also avoid the phenomenon of continuous off. The stability of the first dimmer switch has been greatly improved.

B. RFC transmission mode: Wireless transmission technology is adopted between the LED intelligent dimmer switch and the driving power supply to completely eliminate the flicker phenomenon. Even during the adjustment process, it is very stable and even more does not occur. Relatively smart code adjustment methods have been further improved on the technical level.

In summary, in the field of intelligent lighting, the use, control, and adjustment of LED light sources is one of the most common and most widely used directions. In the field of control and regulation, the matching of switches and drivers plays a role. The key role. The agreement between the two not only results in a better adjustment effect, but also greatly improves the efficiency of energy efficiency, thus helping the promotion and development of smart lighting to a higher level.
