High Voltage Chip Will be The Main Trend of The Future LED Chip Market

The LED is a LED lighting Ⅲ - Ⅳ made ​​compounds, such as gallium arsenide , gallium phosphide , gallium arsenide phosphide and other semiconductor , which is a semiconductor chip as the use of solid fat light materials. Rare metal gallium in the modern semiconductor industry widely used, mainly in the compound gallium arsenide occurs , accounting for about 80% of total applications, gallium , gallium arsenide is mainly used in 3G mobile phones, wireless communications and semiconductor LED lighting on .

Current from the chip market, large LED chip enterprises in market competition has a wide range of products, production, strong supply capacity and other advantages, and therefore itself have sufficient strength to cope with market risks. And small -scale enterprises, product variety , low yields , the price does not have the advantage, overall sales will decline, eventually there may be competitors out of the market . The face of rapidly declining prices of the situation , to reduce production costs , we need to rapidly expand the scale of production to increase production capacity . Expansion can not only reduce the cost , you can also take advantage of scale advantages squeeze competitors in market share.

High voltage and low-voltage chip chip has its own market demand , high chip could be a future market trends , but the current high-voltage chip technology is constantly upgrading , to replace the low-voltage chips dominate the market is still some way to go. High voltage chip products on the market are basically in small-scale production stage. There are two high-voltage chip clear competitive advantage over low-voltage chip :

First , high end chip in chip in series , the reliability with better protection . For packages in terms of saving some solid crystal and wire processes , saving the cost of gold . RC Buck can be used at the same time the way the power scheme can be optimized , power costs declined. For the entire fixture , the systematic saving material cost savings.

Second , the chip can be significantly reduced pressure AC-DC conversion efficiency loss. To 10W output power , for example, if a forward voltage drop of 1W high-voltage chip , you can take the output of 50V, 2 and 4 string configurations , four series LED 's forward voltage drop of 200V, that is to say just from the city 220V AC power (AC) use a bridge rectifier and drop to 20V . But if we use the forward voltage drop of 1W LED 3V low pressure , even strung together 10 forward voltage drop , but also 30V, ie the need to step-down from 220VAC mains 30VDC. We know that the lower the input and output pressure , AC to DC conversion efficiency is higher, such as high pressure visible LED, the efficiency of the transformer can be greatly improved, thereby greatly reducing the power loss of the AC-DC conversion , which a reduction in heat consumption can be further reduced cooling housing costs. Thus, high pressure chip can bring LED lighting to reduce the cost and weight , but more important is to significantly reduce the design requirements of the cooling system , which will effectively cleared the LED lighting into the interior of the largest lighting market technical obstacles. High voltage chip to become a low-cost lighting solution for high efficiency .

2014 development of LED industry , it should be said as a whole for the better, but also will face more opportunities and challenges , driven by the lighting market , chip makers are expected to run high utilization rate , but in the meantime LED enterprise business strategy particularly important. Combined with environmental advantages , so specialized brands , bigger markets, achieve economies of scale is an effective way to deal with the future of LED chip companies market risk .
