LED manufacturers replace aluminum substrates with copper substrate coated insulating thermal paste
  Â
On September 5th, nearly 80% of the input power of high-power LEDs is converted into heat, and the remaining 20% ​​is converted into light energy. Up to 80% of heat energy, if not effectively eliminated, It will seriously affect the service life and luminous efficiency of LED lamps. Therefore, at this stage, heat conduction and heat conduction have become the pain of the LED industry.
   In the LED white backlight ink field for many years, the company has launched a new generation of LED insulation thermal adhesive. This soft pressure thermosetting adhesive has a heat resistance up to 400 degrees Celsius and a continuous heat resistance time of more than 1 hour. Han Dexing, general manager of chemistry, said: LED packaging technology has a new development trend, multi-chip LED package and wafer directly adhere to the substrate COB, should be the current mainstream development. LED substrate manufacturers are also developing toward modular applications, which can reduce the cost of assembly. However, the elimination of thermal energy is still a headache for various LED manufacturers. The heat dissipation and heat management of high-power LEDs is to greatly reduce the thermal resistance between the epitaxial wafer and the substrate, and between the substrate and the heat dissipation mode. Therefore, the thermal conductive adhesive is the behind-the-scenes hero of heat dissipation, not only has low thermal resistance, but also has high thermal conductivity and high temperature resistance. The reflow soldering can not cause the heat-conducting substrate bending plate, the rocking board or the blasting board during the hot baking. Therefore, the new generation of insulating thermal conductive rubber of the crown product completely solves the problem of the bending of the board, and the high temperature resistance can reach 400 degrees Celsius. The thermal resistance value is less than 0.6 cm2.K/W, which allows LED manufacturers to effectively eliminate thermal energy and improve light energy conversion. The manufacturer's lumen per watt can be increased to 120 Lumens.
   Dr. Ye Shengwei, who has worked as a research and development director at the headquarters of Minnesota in Minnesota, and teaches at many universities in China. When developing insulation thermal paste, it is based on the concept of overall thermal resistance. He mentioned the change in overall thermal resistance: the lower the thermal resistance is not only the use of thermal paste, but also the thermal resistance of the interface of various media to which the thermal paste is bonded. For example, epitaxy and substrate, substrate and heat sink If the epitaxial adhesion is applied, the insulating thermal conductive adhesive is applied on the bottom of the epitaxial layer, and the insulating thermal conductive adhesive is integrally coated between the circuit board and the thermal conductive aluminum substrate, and then bonded to the heat dissipation module, the overall thermal resistance can be completely reduced. To make the efficiency of LEDs more effective.
   According to the research, the LED lighting industry is in the era of new and old gradual replacement in 2009. There is still a certain price gap between the new generation of LED lamps and traditional lamps, so that the retail price is the bottleneck in the home market, but the LED lighting industry in Taiwan is still trying to be dramatic. break through the bottleneck, the goal is to be able to develop by the end of 2009, a 5W LED bulb single home price of less than five dollars, the industry conjecture since the end of 2009, LED industry will definitely shine, enter a new milestone.
Icicle & Curtain Lights
The curtain light is mainly composed of a light string and a fixing hook; the light string is formed by connecting light bulb and wire; the fixing hook is a fitting having a wire groove and a hook, and the hook is formed above the wire groove. According to a certain shape, the wires on the light string can be fixed in the wire trough, so that various styles of curtain lights can be assembled., and the whole curtain light can be hung on the frame of the window and door through the hook when in use, and with the light bulb on the light chain to achieve the effect of dressing up windows and doors.
Usage one of Curtain lights: decorative bedroom
In fact, curtain lights are generally made up of a combination of small light strings of different colors, so you can transform a lot of shapes, decorate in all aspects, you can choose a part of the curtain light string, hanging on both sides of bedroom curtains and bedroom door, the ceiling can also be combined with some romantic patterns, and if the light selection is softer, it must very beautiful when the advent of the night lights come on.
Usage two of Curtain lights: decorative bed
The curtain and the bed curtain have similar effect , it can be operated if your bed with a bedpost or a bed curtain, if all the light string of the curtain light are hung on the bed or mattress, or directly take the light as a curtain and it looks like a waterfall when turn it on at night .
Usage three of Curtain lights: decorative wall surface
Curtain lights can be used to decorate walls, it is not only simply hanging on the wall as decoration, but also can be decorated with some murals or room structure, even it can be combined into a pattern or letter and so on. It is convenient to operate and very innovative.
Usage four of Curtain lights: decorative windows
The curtain lights is playing a major role to decorate windows, but the new method certainly not an ordinary decoration, it not only can be decorated on the window frame, but also can use as curtain, and it can sew special pattern on the curtains, then a beautiful pattern will be appeared when you draw the curtain at night.
Usage five of Curtain lights: decorative items
There are several kinds of items in the family unused and not pretty, and the key is that they are indispensable items. Such items are often incongruous in space and obtrusive, so you can use the curtain lights to decorate them, to wrap around them to create different scenery, like some toys can also be decorated.
Usage six of Curtain lights: decorative balcony
The monotonous balcony can also be very romantic. Choose star-shaped curtain light to decorate on the side of the balcony or on the balcony of the plant. Such a balcony is very special.
