Source AC drives the LED module to open a new era

2016 is a leap year, 366 days. Its first day is Friday, the Spring Festival in 2016 is February 8th, and the zodiac is the monkey. In this year, the lunar calendar has no spring, so it is also called the year of the spring (that is, the oligarch).

Here you will say, what is the relationship with the module, I just want to say that the LED packaging industry has gone through the wind and rain for so many years, prices such as the iron stove, cost such as roller coaster, there are too many words to describe the industry, and now, module integration (linear integration) is the word in China. There are many countries around the world. With the large-scale entry of LED to commercial and household lighting, customers have put forward more stringent requirements on the performance, price and reliability of the products.

However, who will be the nose of this linear module, look at the eyes and wait, LED high voltage linear constant current IC, AC drive LED module, on the one hand, the LED luminescence efficiency is constantly improved, the price is constantly reduced, on the other hand, more requirements for the life of LED lamps and lanterns. In the mind of the general people, the life of LED itself is very high, but the actual life life is very low, often due to low power life. At present, most of the lamps and lanterns are the light source + power + shell mode, and the power supply is similar to the traditional switching power principle, the circuit is complex, and the electronic components are more. The production process is complex, the production cost is high, and the failure probability is high. In order to reduce the cost, a number of program companies in the industry launch a high voltage linear constant current IC scheme. This scheme does not need high frequency transformers. Some schemes do not require electrolytic capacitors, simplify the process of the lamps and lanterns, and achieve the purpose of direct driving LED with the market electricity, and the cost is greatly reduced.

At present, source technology Co., Ltd. has launched a part of the module program, a number of LED industry companies have adopted. The main push module of the company has been PF>0.98, efficient >0.95, 80V-265V full voltage support, no strobe, and can only use switch to complete intelligent dimming, and the full set scheme is also less than 3 yuan, single IC support 25W, more than 25W can be parallel. At present, it has reached or surpassed the switching power supply performance, and the industry is leading! At present, the market promotion has been carried out.

The high voltage light source with the advantage of independent core technology, with professional control IC, simplifies the drive design, realizes the stable output of the circuit current, shortens the production material management cost and the assembly process cost in time. The cost advantage is obvious and the cost performance is high. It is suitable for the fluorescent tube, the bulb lamp, the tube lamp, the smallpox light and the shooting. Light and so on.

Product features:

(1) design advantages: integrated design of power supply without inductor; drive IC with 500V high voltage process, the efficiency is up to 89%, and the life span of up to 30000 hours.

(2) high temperature protection, when the limit temperature of 120 C is set to 50% power or closed power output automatically, the production process is reduced, production and maintenance are easy to be produced and maintained, and the size of the custom PCB board can be designed according to the demand of the user's product. When users are in use, they can choose one or more segments according to the needs, such as in the combination of urban and rural areas, the unstable voltage scene in Southeast Asia and so on.

The LED industry is already very mature, and the standard specifications are being further generalized. In the future, the development of general lighting will be more universal, homogenized and standardized, and the power module lighting has the accumulation of time, and it also begins to show its strong vitality. "To power supply" will become an indispensable force in the LED lighting drive market. In the future 1~2 years, the power supply product will account for 30%. The market share of -40%.

It is hoped that in 2016, the industry will blossom.
