Crystal Electronics easy series to create a golden age

Four new light source to lead the LED market trend

The day before, Guangzhou Crystal Electronics LED high power LED market in one fell swoop to market to four in a series of new products, like a bomb, immediately caused a great disturbance in the market. The industry agreed that the new series of crystal easy to create an era of no gold wire packaging, high reliability guarantee allows us to move faster into the full popularity of LED life.

Four easy series new products listed

The blockbuster listing of the four easy series white LED is the latest generation of ceramic based lighting products series, the series of APT patent technology -- flip eutectic technology based on the single chip and multi chip modules without gold, non crystalline solid plastic packaging, is undoubtedly a major technological innovation.

As is known to all, the traditional packaging structure uses the silver glue to fix the chip on the substrate, and it is necessary to realize the electrical connection through the gold wire. Moreover, the silver glue containing epoxy resin, long-term environmental stability is poor, its thermal resistance is high, in the LED long time in the process of the gradual weakening of adhesion, easy to lead to shorten the life of LED.

Because the gold thin as hair, large current impact resistant ability is poor, and only can withstand the force of about 10g, when subjected to thermal shock, due to a variety of packaging material thermal mismatch, easily lead to fracture due to the failure of LED gold.

Without the gold wire package is very good to avoid the above problems, to ensure the high reliability of the product, low heat resistance and ultra-thin packaging, etc.. The launch of the easy series of white LED products four series of products are:

Easy star series E-Star Series (1-3W). Easy star is easy series ceramic no gold package products in the first product packaging of single chip in small size on the 3.5mm*3.5mm substrate, driving light output power up to 3W, and to provide efficient and quality assurance, good reliability, provides a high-quality white light for the client application.

Yi Hui series E-Light Series (5-10W). Yi Hui is a series of easy white LED second products. This product uses the flip chip eutectic welding patented technology, to achieve a multi chip LED module without gold wire packaging, with high brightness, high reliability, low thermal resistance, good color uniformity, etc.. Yi Hui in the small size of the substrate 6.0mm*6.0mm package, 4 high-power chip, the input power can support 5-10W, for commercial, Home Furnishing, outdoor and vehicle lighting and other lighting provides a high grade and high quality light source.

Easy flash series E-Flash Series (for flash). Easy to flash is a series of ceramic based gold wire packaging products for the design of flash applications for a white LED products. This product is easy to give full play to the advantages of no gold series, can use the pulse current is above 1000mA drive, the instantaneous output pulse with high light intensity density, and can realize ultra-thin, ultra small size package, will flash for a variety of applications of digital products, intelligent transportation system provides a highly efficient, high quality products.

Yi Yao series E-Shine Series (above 10W). Yi Yao is a series of ceramic based non gold line packaging products can be customized according to customer requirements of white LED integrated light source products. This product adopts flip eutectic bonding technology, no gold package multi chip, single light source can be driven to more than 10W, the output luminous flux of more than 1000lm, and has the characteristics of high reliability, low thermal resistance, light color uniformity, especially suitable for single nuclear lamps, provide a high quality and easy to use the light source for customers.

Four technical advantages lead the LED trend

Easy series of new products can cause a sensation in the industry, because of its unique and innovative technological advantages. To sum up, the new series of easy to have a total of four technical advantages:

First, high reliability. As we all know, the use of multiple chips or vertical chip package LED module, the chip and the chip, the chip and the bracket are required to use gold wire to complete the electrical connection, increasing the risk of LED failure. The high reliability of the easy series flip chip packaging structure is more obvious in the LED module.

Second, low thermal resistance, can be used in large current. Due to the traditional packaging, the sapphire layer in the bottom of the chip, so that poor thermal conductivity, thermal resistance of silver glue is also very high. On the other hand, the metal structure is directly contacted with the metal, so the thermal conductivity is high and the thermal resistance is small. (pictured below)

Again, the plane coated phosphor, uniform color. The traditional phosphor coating method is not uniform, and the color temperature is large. The improved technology is a more uniform spatial color temperature distribution. (pictured below)

Finally, no gold wire barrier can be achieved in ultra-thin packaging. Without the gold thread, the phosphor coating is simpler and provides more space for the lens design. (pictured)

From a technical point of view, crystal electronics series of new products have been a lot of innovation and beyond, which is the embodiment of the overall strength of electronic technology. We have reason to believe that easy series of products not only lead the future market demand for LED, while leading the trend of LED industry technology innovation.
