It is well known that a single LED has low power. In order to achieve high power, multiple parallel uses, such as automotive taillights, are required, and a single high power LED is expensive. Another fatal flaw in LED, low color rendering index! The color displayed under the LED illumination is not as true as the incandescent lamp, which is analyzed from the spectral distribution and is a technical problem. The main pain points in obtaining customers in foreign trade are fierce market competition, high customer acquisition costs, low customer stickiness, and single marketing methods. With the changes in the market environment, traditional marketing methods Orange sample Bossgoo(China)Tecgnology , https://www.cn-gangdao.com
Another disadvantage is the "spot". Due to the defects in the manufacturing process of the white LED itself and the matching error with the reflective cup or lens, the "yellow circle" problem is easily caused.
The current disadvantages of semiconductor lighting are mainly in the following two aspects:
1, high power LED price is higher
At present, the market price of high-power white LEDs of 1 watt is about ten to several times that of traditional light sources.
2, high power LED application low light efficiency
The high-intensity light-emitting diodes with a commercial power of more than 3 watts have low luminous efficiency, and the high-intensity gas discharge lamps with a luminous efficiency of less than 100 lumens per watt are also lower than the rare earth trichromatic fluorescent lamps of 60 lumens or more per watt. It is said that semiconductor lighting saves power and saves energy. It is actually set up in a small power range. When using current semiconductor light sources to make high-power lighting fixtures, it does not save much energy compared with existing high-efficiency light sources. On the contrary, the initial input cost is very high. high.
Another problem with low light efficiency is that a large amount of input electrical energy is converted into thermal energy. It is said that the luminous tube is a cold light source only that the illuminant itself is not a burning body, but the resistance heat generated by the large current on the semiconductor material still causes the luminous tube. The higher temperature is generated, and the light-emitting diode made of semiconductor material is not resistant to high temperature, and the overheating will greatly reduce the service life. The heat dissipation by the heat sink increases the volume of the lamp, and the advantage of small size and light weight of the semiconductor light source disappears.
According to the above analysis, in terms of luminous efficiency and price level, it is not easy for a semiconductor light source to truly enter the general lighting field to replace a conventional light source in a short period of time. To solve these problems, the luminous efficiency of the luminous tube is greatly improved and the production cost is greatly reduced. However, under the current state of the art, the development of the semiconductor lighting industry to foster strengths and circumvent weaknesses, and actively develop in the direction of advantages, promoted its technological advancement and maturity of production processes, enabling the era of semiconductor lighting to come early.
