LED light source lamp bead products, market overview

The high-power lamp beads used in semiconductors on the market today are very different. It is different to use an idiom to describe them. There are advantages and disadvantages to this kind of lamp beads. We have to look at this issue dialectically. People in the industry have different views on this type of information. According to the above analysis, we can make a few simple predictions on the mainstream light source of high-power LED lamp beads : First, from the perspective of illumination, the application is difficult. Cost considerations, lighting LED high-power products can be direct white light, rather than RGB-controlled mixture to produce white light.

Considering the difficulty in manufacturing LED products and the luminous efficiency, the high-power LEDs around 10w are still the main lighting. Because each customer's requirements are different, we must be more in line with customer needs. The characteristics of the new power LED lamps in the market are: planar patching, device miniaturization, flooding type with floodlight type, heat and voltage management separation, single optical power is not large and so on.

In the market, there are many kinds of LED products, so there are many kinds of classification standards. Therefore, we can classify according to the color, characteristics, structure, brightness, working current of the LED, power of the LED, packaging method, etc. of the LED lighting.

First, it is classified according to the color of the light. In the color section, we can divide the LED color into green, yellow, and blue. In addition, in the light-emitting chip, there are single chip, two chips, and three chips. However, the size and size of these three chips are different, both large and small. According to the LED light, whether it is colored or no color, whether the scattering agent is added, whether it is colored or colorless.

Second, it is classified according to the shape of the light-emitting surface. The shape of the LED is round, square, rectangular, and the like. The size of the circle is divided into many different types, such as f2, f4.4, f5 and so on.

Third, it is classified according to brightness and current, normal brightness and high brightness. The unit of brightness is mcd, which can also be expressed in lumens.

Fourth, according to the structure classification of LEDs, it can be divided into epoxy, metal base epoxy package, ceramic package and glass package.

Fifth, classify by power. The power of LEDs is different. It can be divided into low power, medium power and high power. Sixth, the LED package can be divided into two types: patch and in-line.
