LED Cabinet Light Design Of Metal Heat Dissipation Structure
East Bright Technology Limited | Updated: Sep 19, 2017

In the shopping malls container and display cabinets, corporate filing cabinets or in hotels, home cabinets, wardrobe, will use the back lights. The traditional backlight mainly to MR16 halogen lamp, not only high power consumption, so that the temperature in the cabinet is very high, there is the possibility of storage damage in the cabinet, and because the halogen lamp service life is short, the need to constantly replace, increased maintenance costs. Now with the LED product production process improvement and price decline, gradually use LED as a cabinet lamp, and has been widely promoted.

1, LED Cabinet lamp product characteristics are: the traditional lighting and the most new energy-saving environmental protection light source, the use of small power led as light source, the use of metal cooling structure design, the use of high-quality glass surface sand production, light transmittance as high as 93%. LED cabinet lights can be used as home, commercial offices, building public places, furniture, hotels, store cabinets, entertainment lighting auxiliary lighting, its application is very wide. The use of LED lights can not only meet the traditional lighting and control requirements, and can be used red, green, blue led, play a role in rendering. LED Ambry lamp main characteristic is: breaks the traditional illumination blind area, enhances the modern home life quality, the special light and shade constructs the environment new atmosphere.

2, LED Cabinet lamp has a wide range of uses, whether used in the kitchen, or as a wardrobe, display cabinets of light irradiation, its common denominator is the position of the cabinet is relatively fixed and the size of the cabinet itself is relatively large, once installed in the above cabinets will not easily move, and according to the entire LED cabinet lamp reliability is higher. LED cabinet lights are mainly composed of LED lamps and driving power supply, and according to the use of the cabinet lamp conditions, LED lamps are usually intermittent, LED lighting is not the main factor, affecting the entire led cabinet lamp reliability is driven by the power supply to bear.

3, as to the LED lamp radiator is how to design it? LED cooling design materials and components are mainly thermal design materials have thermal substrate, condensation layer materials and cooling device 3 kinds. The function of the heat dissipation substrate is connected with the hot layer inside the LED, and the heat is exported and distributed, which is the technical means to solve the problem that the circuit connection between the unit led and the heat dissipation channel are independent. The thermal substrate has a metal PCB, but there is a large expansion coefficient and relatively independent of the problem to take the technical means. The heat dissipation substrate has many problems such as large composite coefficient of metal PCB and metal base and large relative density. Metal Matrix Composite is an improved type of metal PCB, which has the characteristics of high thermal conductivity, small relative density and adjustable expansion coefficient.

4, LED chip and heat sink bonding materials have thermal adhesive, thermal conductivity of the degree of hardening of less than 150 degrees of low thermal conductivity, poor heat conduction effect. As for aluminum, the highest concentrations of metal in the Earth's crust because of high thermal conductivity, small density, low price and welcome to become the radiator processing ideal material selection; but because of the small hardness of pure aluminum, in a variety of applications in the field is usually mixed with a variety of formula materials made of aluminum alloy, in order to obtain many of the properties of pure aluminum. Various types of aluminum alloy molding, processing methods, applied to different areas of the way, especially the application of aluminum alloy LED cabinet lamp is particularly popular at home and abroad users.
