[Brand Power • Hongli Photoelectric] LED lighting mainstream devices and development trends

At present, the form of LED packaging devices is changing with each passing day. From SMD to COB, from flip-chip to chipless packaging, it has injected a lot of new vitality into the development of the industry. Nowadays, the mainstream lamp bead 2835 is also the main product of Hongli. It can be widely used in the production of bulbs, downlights, PAR lamps, panel lamps, lamps, mining lamps and other products, covering power from 0.1W to 2W.

Wang Gaiyang, Director of Hongli Optoelectronics Products

According to the current development of the LED industry, I believe that the future development trend of LED lighting mainstream devices mainly has the following four points:

The first trend is the flip-chip process, which has solderless wire, better reliability, low thermal resistance, and overcurrent use. It can use eutectic process, silver glue process, solder paste process, etc., and the market competitiveness is good.

The second trend is flip-chip COB and high-density LED array new products. Its unique structure and performance provide more possibilities for LED lighting in high lumen density applications.

The third trend is flip-chip discrete devices for applications such as cell phone flash, TV backlighting, and lighting. The use of flip chip process, with higher current carrying capacity, higher unit area brightness output; its thermal resistance is about 6 ° C / W, better thermal conductivity; using phosphor molding technology, better consistency.

The fourth trend is the AC module, which has the characteristics of low cost, PF value greater than 0.95, THD less than 20%, and convenient assembly, which is convenient for later replacement and maintenance.

1200V DC Electronic Load System

1200V DC Electronic Load System has battery discharge function, and can perform discharge test under CC, CR or CP mode. The DC load can set end voltage or time to stop loading correctly and make sure the battery is not damaged due to over discharge. The user can set stop conditions, whenever met any condition, the load will stop loading and counting automatically. During the test, users can observe battery's voltage, discharging time and already-discharged-capacity.1200V DC Electronic Load system including 39600W/52800W/66000W.BTW,if the 1200V is too big voltage for application,it can also choose lower 200V DC Electronic Load System and higher 1200V DC Electronic Load System .
