The US high-brightness LED market in 2004 increased by 37% from 2003 to reach $3.7 billion. The logo ranks second in the LED market application, accounting for 13% of the market. In 2004, the US high-brightness LED market application ratio is as follows: the first place is the application of electronic digital products, including (PDA, telephone, camera, etc.), and the second is the logo and automotive industry, respectively, 13%, the first Four are 9% for other applications and the fifth is for lighting 5%. The sixth place is 2% of the signal product.
Compared with the accurate survey data of the US market, there is currently no investigation report in this area in China, but the strong momentum of LED in lighting is unstoppable, compared to the LED market, sports, retail and logo of basically saturated electronic digital products. It will be an important force to promote the development of high-brightness LEDs in the future. LEDs have changed the way logos are designed. In less than a decade, LEDs will affect the classification of charged signs.
The application of high-brightness LEDs in channel type and architectural lighting is increasing. Red LEDs dominate the channel type, and the remaining color LEDs are also greatly improved in brightness and power. The growth of slotted word illumination in the future will depend on transistor illumination. As the market demand increases, LED will not simply replace the existing lighting methods such as incandescent lamps, neon lights, etc., but attract more users with reasonable design costs.
With the rush of the market, as a consumer, LEDs still need to be calm, scientific analysis, select the best cost-effective light source and lamps, the following describes the basic performance of several LEDs, to give readers a reference.
1, brightness
The brightness of the LEDs is different and the price is different. LEDs for LED luminaires shall comply with the laser class I standard.
2, antistatic ability
LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.
3, wavelength
LEDs with the same wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4, leakage current
The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called a leakage current, and the LED with a large leakage current has a short life and a low price.
5, the angle of illumination
LEDs with different uses have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
