LED light source products will become the substitute of green energy, the continuous innovation of product development, and has the advantages of smaller volume, higher efficiency, the greater the wattage, the lower the price will become the future trend of LED development。And can meet the requirements above。In recent years, due to the global energy consumption and environmental deterioration, countries rising awareness of environmental protection, have been putting forward proposals to ban incandescent bulbs and other policies. LED lighting products become the alternative green energy, in constant innovation in product development, while smaller, more efficient, the greater the wattage, the lower the price will become the future trend LED. Some of the limitations of the traditional materials development, but in recent years the ceramic substrate package, launched a broader advantage, making the development of LED, can meet the above requirements.

B, High-Brightness LED Future Trends Beginning in 2009, beginning of concern that LED lighting source products。due to energy saving, high efficiency, mercury-free, long life … and other characteristics, and gradually began to flourish, and various concerns, so in 2010，some manufacturers have added lighting the ranks of the application of LED。Looking to 2013, in the world, including the United States, China, Korea, Taiwan … etc., are committed to accelerate national and industry standards, making poor physical LED manufacturers will face the fate of the closure and consolidation, which will increase the relative consumer confidence (including governments, businesses and consumers in general), after 2014, LED lighting will be price, quality and efficiency reaches a certain level,
so that the demand of LED will be quickly grow up.

LED packaging form divide of separation and integration。LED separation device belongs to the traditional form of packaging, widely used in various related fields, after nearly forty years of development, has formed a series of mainstream product form. The LED COB module  belongs to the personalized packaging forms, mainly for the application of some cases and personalized product design and production, has not formed the mainstream form ofproducts.Semiconductor lighting to enter the general lighting field, the cost of production is the first major constraints. To reduce the cost of semiconductor lighting, we must first consider how to reduce the cost of the LED package. The traditional approach is LED lighting: LED light source module separation devices → MCPCB lighting module→ LED lamps, mainly based on the core source components do not apply and the approach is not only time-consuming work, and high costs. In fact, we can be “LED light source module separation devices → MCPCB lighting module” combined the MCPCB lighting module and LED chips together to make COB light source module direct, take the “COB light source module → LED lamps” route, not only can save time, but it will save the cost of the device package. The cost, compared with the separation light source device, COB light source module can save device packaging costs in lighting product applications。light engine module production cost and the secondary light distribution costs.In the same function lighting system, the overall cost can be reduced about 30%, which is for the promotion of semiconductor lighting applications has great significance. In performance, through rational design and molding microlenses, COB light source module can be effectively avoided discrete light source device present in combination in the light, glare and other disadvantages, but also by adding an appropriate red-chip combination, without reducing the light efficiency and life under the premise of effectively improving the color of the light source (now can do 90 or more).

The smooth silicon surface has high reflectivity with aluminum metal layer。LED welding surface coated with gold, in order to provide the best heat conduction, and the chip and the lead frame， The bonding strength of copper radiator.ledlight local to the integral package structure schematic diagram. Its main characteristics: low thermal resistance ( 14 ℃ /W),only conventional LED of One of ten equal parts; high reliability,flexible package filled inside with the gel stability, at 40 to 120 ℃,
when due to temperature change can not be generated the internal stress,so that the wire and lead frame of a disconnected, and prevent the epoxy resin lens lead frame change to yellowing, nor because of oxidation and smear; the design of reflector cup and lens to make the radiation pattern, improve the efficiency of controllable optical.
In addition, the output optical power, good external quantum efficiency, LED solid state light source development to a new level. The wafer is thin, so it can play the maximum effectiveness of heat conduction，let the LED heat dispose quickly through this to the radiator.
In all kinds of ledlight products, a primary heat sink (Slug) (thickness of about 1.5mm) through the epoxy paste on MCPCB. The interconnection between MCPCB security of electricity (electrical interconnect), also with the second stage heat sink connection interface. In case no aluminum heat sink under the second level, LED can work under the room temperature, but the MCPCB is easy to reach 70 ℃.
Though the Multistage heat sink has a little resistance increased,but the Package and heat dissipation of high power LED The radiating surface greatly expanded (thermal conductivity in channel heat sink is often called the heatspreade two thermal diffusion layer, in the three dimension should have higher rate), so that the convection and radiation heat dissipation capability is greatly enhanced, and thus the whole system is improved.ledlight local to the integral package structure sketch。another figure limit the maximum junction temperature is a silicon carrier and inter chip due to different thermal expansion coefficient of the maximum allowable limit thermal stress. In many cases, high power LED chip by transition of Submount or heat spreader, mounted on the MCPCB, while the MCPCB close to the aluminum heat sink, both smooth surface or spring-loaded screws fastening。

Package and heat dissipation of High Power LED,also has the relationship between junction temperature and LED color. Generally under normal light color is most pure, junction temperature will result in increased or decreased light color drift. Different wavelengths of light
has different the temperature sensitivity。The least sensitive to the highest sensitivity green light, The blue lights has bad sensitivity。
In any case, color drift will make the color temperature is not stable, affect the optical properties of white LED.The structure and principle of High-power LED heat dissipation Package LED Chip heat by conduction to the heat sink, heat sink through the air convection or outward radiation. In the high power LED cooling channel, MCPCB (meta1 core printed circuit boards) is connected with the internal and external cooling channel, at least the following functions:

1) Radiating channel of High Power LED chip；
2) electric LED chip connection；
3) The physical support of LED chip. Substrate materials for high power LED must have electrical insulation resistance, high stability, high thermal conductivity。 A few metals or alloys can meet the high thermal conductivity and low expansion coefficient requirements, To assume for electrical insulation， need to be coated polymer film (rarely have high thermal conductivity) or the deposition of a layer of ceramic film. Ceramic material of difficult processing and high cost, some semiconductor material physical parameters can well meet the requirements of the same substrate material, high cost, they are unlikely to be used for general lighting of the LED, but you can use a small as carrying LED Submount (one level heat sink), insulation function, attached to the heat sink (two level heat sink)。Power LED LumlledS as flip mode, with the silicon chip as the heat sink. Provide electrostatic protection through the zener diode of integrated in the silicon heat sink, this design can reduce the mismatch of thermal expansion coefficient of impact (silicon and sapphire substrate have similar thermal expansion coefficient). In addition, the silicon material and solder ball playing stress absorber, in order to further relieve the thermal expansion effect. In the silicon carrier adhesive solder ball makes the LED chip closely with silicon carrier joined together, and then the line connected to the lead frame.
