LED color, the color is different, the price is different. White, green as a result of matching color and spectroscopic color separation is more difficult, so the price is higher than the price of other colors; Red, yellow, blue and other colors are easier to separate colors, and the consistency is better, so the price is slightly cheaper. Special colors, such as purple and brown, are the most expensive because of color matching. LED size: different specifications and sizes of LED, the price is different. Such as 0603 LED and 1210(that is, 3528) LED, the price difference is large; And the price of 1210 and 5050 specifications LED is another step apart.
For profit, it is impossible to cut corners in the production of LED. Therefore, LED lights in the home use has appeared the user described in the beginning of the problem. However, the advantages of LED products can not be erased, high-quality LED lights are indeed “less power consumption, long life”. LED energy-saving lamp is still the trend, in the long run, only by solving the technical difficulties, LED energy-saving lamp can really reduce the cost, from street lighting, landscape lighting, into the wider market.
As a key component of smart cities and smart sports venues, LED screens of different sizes and functions are widely used in venues and urban construction, and Chinese companies have “picked up” the “girder” of LED screen supply. “With the digital, information and intelligent development of The Times, the construction of major sports venues is also advancing with The Times, and the layout of intelligent and digital actively. Among them, professional LED screens have become important facilities.
The reason for the cracking of the LED chip is analyzed: the mechanical stress forms a relative shear force between the two electrodes of the LED chip, and directly acts on the LED chip through the convex point, resulting in the cracking of the thin and brittle LED chip. The generation of mechanical stress is related to thermal stress. For this LED failure mechanism, it is recommended to improve the package of the device, such as adding filler between the chip and the substrate, providing mechanical support for the chip, and reconciling the mechanical stress caused by the difference in the coefficient of thermal expansion between the substrate, copper strip and LED chip.
