LED lamp beads development trends

This is due to write the headline message before a friend asked me to see how China's LED market. Dare to write something unfamiliar to mislead you, so just write about changes and trends buy led high bay lamps this small market, to bring the development trend of LED devices in the eyes of an engineer.
One, SMD 2835 turned gorgeous
    From the beginning of the end of 2011, there has been SMD2835 this device on the lighting market. The beginning of the stent design from SMD3014 bracket, solid crystal location directly on the pad, cooling area larger heat conduction path is shorter. At the same time by the lighting market demand for luminous flux, luminous flux output single product requirements higher. Due to the larger solid crystal position, more chips can be arranged to form a certain string and combinations. This gives packaging factory brings more opportunities for product positioning.
Power: Now the market common SMD2835 from 0.1W ~ 1W have, change to a different scaffold materials and substrate can be achieved more product categories.
Material: 0.1W stent is made of plastic and iron substrates PPA produced, 1W substrate will adopt copper, plastic materials, some manufacturers use PCT.
Voltage: For voltage speaking, 3V ~ 45V has. 3V using single or multiple satellites in parallel. Some companies are using higher voltages more stars 3V chip series, there is also high voltage chip production.
Trends: Domestic companies are the main push SMD2835, now Taiwanese companies and Korean companies are ready to develop SMD2835 this product, along with a further increase power, and cost requirements for lighting companies to replace SMD5630 is just around the corner.
Two, SMD5630 dynastic decline
Speaking SMD 5630, the first to mention, of course, the Samsung LED backlit TV. With LED energy-saving effect gradually reveal, growing, increasingly thin LCD product size dimensions. Backlight requirements are also increasing. Traditional T1, T2 section at the bottom of the tube light mode can no longer reduce the thickness of the machine. led high bay light for sale are able to meet these needs constant good. With respect to the smaller power LED, SMD5630 can provide more flux, better design method, the side light arrangement.
From the power of speaking, SMD5630 power products can provide higher heat dissipation than SMD3528. Support structure design also allows for heat dissipation and light output. In the lighting industry, due to the linear lamps, tube lights alternative markets such as the outbreak of more inspired SMD5630 expansion step in the lighting market. SMD5630 were making use of the lamp can be light-efficient products, and its optical design is also more conducive to the use of linear lighting market. Currently Korean series, the Taiwan-based firm's major competitive market is SMD5630, SMD5630 which forced prices have been falling. After entering the lighting industry, companies require even more than the cost of the backlight. More price decline led SMD5630 products. Meanwhile, the cost of future breakthroughs more bottom line, instead of using SMD2835 SMD5630 is already a big trend.
