High-power LEDs are one of the most important means of achieving high luminous flux. There are many advantages and disadvantages to using high-power LED lighting. How to use high-power LED is the key. At the same time, it compares high-power LED lighting products with traditional lighting products, and also discusses the application of high-light LED in lighting field.
First, the development history and application potential of LED Since the birth of LED, the brightness of the "Haitz" law has increased by 30 times every 10 years, and the price has dropped 10 times. Ordinary high-brightness white light LED has reached the level of 100lm/W in the laboratory, and 50lm/W high-power white LED has also entered commercialization. In terms of monochromatic light, the light effects of red, yellow, blue, and green light are constantly being recorded. LEDs as a new type of light source have become more and more widely used, and have gradually attracted more people's attention and expectations.
At present, LED applications are diversified in various industries, including indication, display, backlight, and lighting. Lighting is the most promising industry for many LED applications. With the continuous improvement of LED light efficiency and the continuous reduction of cost, its market in the entire lighting field will also expand. Following the US “Next Generation Lighting Planâ€, Japan’s “21st Century Lighting Planâ€, the EU’s “Rainbow Plan†and South Korea’s “Solid State Lighting Planâ€, in 2003 China established the National Semiconductor Lighting Engineering Group to integrate resources, Rapidly push LEDs into the lighting market. According to the prediction of Academician Chen Lianghui of the Chinese Academy of Engineering, China's semiconductor lighting can accumulate 400 billion kWh of electricity in 2005-2015, saving users 160 billion yuan in electricity bills, creating 150 billion yuan in output value and solving the employment of 1 million people.
By then, the annual energy saved by semiconductor lighting will exceed the "big Mac" - the annual power generation of the Three Gorges Power Station! In the context of the growing shortage of energy, the use of LED energy-saving features, the development of LED lighting is a positive response to the government's proposed conservation-oriented society.
Second, the characteristics of high-power LED and compared with other light sources LED is called "green light source" deserved. In the lighting industry, comparing it with traditional light sources, some aspects show an irreplaceable advantage: LED as a light source for lighting has the following advantages:
1. Low power consumption: LEDs with a luminous efficacy of 75 lm/W are reduced by about 80% compared with incandescent lamps of the same brightness;
2, long life: product life of up to 50,000 hours, 24 hours of continuous lighting available for 7 years;
3, the dynamic control of brightness and color is easy: the brightness can be continuously adjusted, the color purity is high, and the color dynamic conversion and digital control can be realized;
4, flexible size: can achieve organic integration with the building, to achieve the effect of seeing only the light;
5, environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation;
6, color: bright saturated, pure, no filter, red, green and blue three-color elements can be adjusted into a variety of different colors, can achieve variable, variable, mixed light effect, color rendering effect is excellent. With so many advantages in one, we feel that it is a valuable job to promote the use of LEDs.
However, compared with other light sources, LEDs also have insufficient aspects, such as low color rendering in white light illumination. White LEDs currently produced with yellow phosphors and blue light have a color rendering index of about 80. It is ok as general lighting, but it is insufficient for some places where color resolution is high. Although the color rendering index can be increased to 90 or higher by adding an appropriate red phosphor, etc., there is still a certain gap compared with the 99 of the incandescent lamp, and the efficiency thereof is affected. Color rendering can also be improved by RGB color mixing, but more work needs to be done in the popularization of technology, so LEDs need to be improved in terms of color rendering. As for the high price and large one-time investment, in fact, from the perspective of comprehensive cost, the use of LED in many occasions still saves a lot of cost.
3535 Blue SMD LED got a bigger size than the others SMD LED, which mean it will got a wider beam than the others SMD LED. People always deeply loved by their high brightness.
It is often used in LED lighting, LED Lamps, LED backlight, LED panel lights, LED furniture, grow light LED, fill light LED, LED aperture and other lighting products.
