With the gradual increase in the penetration rate of the global LED replacement lighting market, more companies have begun to increase R&D and product launches in terms of product intelligence.
At the same time, major markets such as Japan, Europe and the United States have put forward more requirements for high efficiency, long life, high power factor, flexible expansion, dimming, etc. of LED lighting products, making LED and power industry continue to face product innovation.
In this context, Shenzhen Laifu Photoelectric Co., Ltd. (hereinafter referred to as "Lyford") as a domestic professional manufacturer of LED constant current driving power supply, successfully developed a new technology in October this year "a parallel synchronous dimming technology ", and pushed to the market.
The traditional parallel dimming scheme simply connects the modules in parallel to the same dimming unit. Because of the internal resistance of the parallel connection line itself, there is an error between each signal detection circuit and the reference circuit, resulting in the output current of each module cannot be consistent. And the switching machine is not synchronized; and the dimming effect varies with the number of power supply parallel units, resulting in the same dimming degree, the more the number of parallel units, the greater the output current of the power supply; the more the number of parallel units, the minimum adjustment The larger the current, the more the dimming unit is modulated, the larger the current is still output by each module.
The "parallel synchronous dimming technology" developed by Leyford for the above problems can provide a simple circuit structure, convenient engineering installation, and versatility and machine dimming technology. This technology has the dimming effect that does not change with the number of parallel machines, the dimming depth is high, and the dimming degree of each module is consistent, and the switching machine is synchronized.
In order to save costs and meet the dimming requirements, power companies often adopt a parallel mode, that is, a dimmer is connected to multiple LED driving power sources. At present, the market dimming is still using the traditional scheme. When multiple units are connected, the dimming performance will inevitably deteriorate. Even if the single LED driving power supply has excellent dimming performance, when multiple units are combined, the dimming performance will be Very poor. Mainly reflected in the following three aspects:
1. The dimming depth is not enough, and the more the dimming depth, the shallower the dimming depth;
2. The time of each LED driving power switch is not uniform;
3. The dimming brightness of each LED driving power supply is inconsistent.
Looking at the "parallel synchronous dimming technology", after the innovation, the cost of the drive itself is hardly increased, and multiple LED drive modules are simultaneously synchronized and dimmed. Compared with the traditional dimming scheme, its market competitiveness is mainly reflected in the following five aspects:
1. Simple installation and convenient engineering practice;
2, the dimming depth is good, does not change with the increase in the number of parallel machines;
3. The dimming brightness of each LED driving power supply is highly consistent;
4, will not increase the size of the LED drive power supply;
5. Compatible with all standard dimmers on the market.
It is worth mentioning that although the "parallel synchronous dimming technology" has been introduced to the market for a short time, it has been highly recognized by many customers.
The following are some customer reviews:
1. Stability performance, 3-5 years ahead of the industry;
2, Leifford has always adhered to technological innovation, leading the industry's technological breakthroughs, is a practical enterprise;
3, the technology is excellent, the product iteration speed is faster;
4, Leifford's latest US standard dimming power supply in the dimming consistency by our company is very good, big brands are trustworthy;
5. In today's transparent industry, Leifford dares to innovate and dare to break through, and the designed product performance is at least 5 years ahead of the industry average;
6, Leifford technology has been in the industry leading level, to solve the actual needs of end customers, we believe in Laiford.
Based on the unique innovation and strong market competitiveness of “Parallel Synchronous Dimming Technologyâ€, Leifford decided to bring the technology to compete for the 2017 “High-tech LED†Technology Innovation Award.
