Four LED innovative packaging technology

Introduction: in recent years, with the popularity of LED lighting and LED display applications to expand the market for LED packaging technology has also put forward new requirements, the following look at some of the gratifying achievements in the field of LED packaging.

Four LED innovative packaging technology:

Three in one

Three has been inserted into the current product upgrade products, and did not change the traditional line of light packaging process, but in the product mix and break through the combination of the RGB seal in a light, the use of four feet. The traditional color to three single lamp as a phase point, now as long as a single lamp can do the same effect, which greatly reduces the cost of production and materials, so that the product has excellent price competitiveness. Outdoor three in one to solve the user display performance and weather resistance can not have both the dilemma.

Piranha

Piranha LED, is a package, square, transparent resin package, four pins, the negative electrode has a foot LED. Piranha is a diffuse type of LED, luminous angle greater than 120 degrees, high luminous intensity, and can withstand greater power. Car brake lights are used for more. It is said that this kind of LED has just been born when it immediately aroused the concern of the people, the development trend is as fierce as the piranha. The other is because it's shaped like a piranha in the amazon. Piranha series display, is a traditional line between between the lamp and the traditional indoor surface mount lamp three has been compared with the traditional lamp, outdoor 246, 346 line lamp made of screen, piranha series 5353 high brightness, white balance, excellent consistency, red green and blue light from the perspective of synchronization, gold wire wick and the failure rate is low, these are the biggest highlight of the piranha series.

The piranha 5353 completed outdoor full-color display protection grade can reach more than IP65, from positive / side, 246, 346, 546 to eliminate the lamp has been unable to solve the "Huaping spots" phenomenon. The heat is better than the commonly used 3528 and 5050 outdoor surface mount three in one made of beads. According to industry sources, the outdoor three lights have been inserted into the market prospects than the traditional direct light and table stickers more impressive.

COB

Chip on board (ChipOnBoard, COB) process is the first surface of the substrate with a conductive epoxy resin (epoxy resin mixed with silver particles with covered silicon) placed, and then placed in a silicon wafer direct heat treatment to the silicon substrate surface, firmly fixed on the substrate, then by wire bonding between the silicon wafer and the substrate directly establish electrical connections. If bare chips are exposed directly to the air, susceptible to contamination or human damage, affecting or destroying the chip function, the chip and the bonding leads are sealed with glue. People also call this package for the envelope.

COG

The utility model can be used as an integrated packaging technology with different substrates. The sapphire substrate integrated packaging technology for the new development can enhance the brightness of 30% COG, this product will be LED sealed in glass or sapphire plate on both sides, because the intermediate substrate color transparent, light LED will be more uniform, and this product is omitted support process, can reduce the cost of product support, also simplify the process advantage.
