HANDSON Service Center building LED indoor lighting case (Figure)

Editor's note: the advent of high-power LED time is not long, but because of its long life, energy saving, environmental protection, small size and a series of advantages, there is a trend to replace the traditional lighting source. The huge potential of semiconductor lighting industry and the construction of a conservation minded society great demonstration effect caused great concern in domestic provinces and municipalities, have formulated a series of development planning, in order to promote the local development of semiconductor lighting industry, at the same time in the global lighting revolution tide to seize the initiative.

Although the price factor is widely used in high power LED, but did not stop its application in landscape lighting and special lighting industry, because of high power LED high reliability, greatly saves the maintenance and replacement costs; bright color, the other light source fails to effect; easy to control, through the digital control technology reach, dynamic lighting effect; small volume, can make the lamp more creative; in some special places because the environment needs to be applied to high power LED lighting, such as mining, explosion-proof, military and other fields. But in general indoor high power LED lighting is not enough to shake the dominant position of the other light source, this is mainly because the initial purchase LED lumen cost is still relatively high, but with the LED luminous efficiency increasing, the total cost of ownership advantages in indoor lighting also emerged.

Application of high power LED in indoor lighting

HANDSON company service center building was completed in April 30, 2006 put into use, the whole building lighting all the use of high-power LED lamps. When night falls, service center building a bright highlight in the garden park, constitutes an important part of the park lighting.

Indoor lighting part of the entire building a total of 130 lamps on the grid, 506 Light Chandelier Lamp downlight, ceiling lamp 69, 20.

According to the test and analysis, although the high power white LED on the luminous efficiency is inferior to the fluorescent lamp, energy-saving lamp is high, but in the production of a LED lamp, LED light source to strong advantages easily reflected, efficiency of the LED lamp is higher than traditional lamps, illumination reached 300lux after the test desk, reach the national standard.

High power white LED light efficiency of 40lm/W, the traditional incandescent light efficiency is only 12lm/W, and LED lamp efficiency is higher than 1.5 times more than traditional lamps. Initial investment, LED lamp total power of 9938 watts, to achieve the same lighting effect, the traditional incandescent light source total power of 32000 watts. Table 1-1 analysis of the "service center" building using LED lamps and traditional lamps initial investment.

Table 1-1 comparison of costs of using LED lamps and conventional lamps

The use of high-power LED lamp though the initial investment cost will be higher than traditional lamps, but in five years time when the total cost of consumption is lower than the traditional lamp, after will save electricity and maintenance costs 76 thousand yuan per year. Therefore, the use of high-power LED in indoor lighting is better than the traditional incandescent light source. And because of high power LED are using constant current drive, no stroboscopic, long time working environment without fatigue.

Due to the current high power LED indoor lighting, LED light source part of the cost of a very large proportion, thus reducing the cost of high power LED light source unit lumen is the key. If the luminous efficiency of LED reached 100lm/W, and the price is now reduced to half, in the case of traditional light source light effect at the same time, the total power is 3976 watts LED lamp, to achieve the same lighting effect, the total power of 31570 watts of traditional light source. We can make a comparative analysis, as shown in the table:

Table 1-2 comparison of costs between LED lamps and conventional lamps (LED:100lm/W, the price is reduced to half of the present)

As can be seen from the above assumptions, the luminous efficiency of high power white LED reached 100lm/W, the price dropped to half now, in general white lighting in the field of competitive advantage can be reflected, basically two years can recover the initial investment.

Problems and overcoming

Despite the high power LED to replace the incandescent light source has shown obvious advantages of energy saving and long life, the efficiency compared with the traditional lamp efficiency LED lamp has been significantly improved, but compared with fluorescent lamps, energy-saving lamps, its energy-saving effect is not very obvious. Of course, the white light LED lamps in the face of the traditional lighting in the field of general lighting competition is the biggest problem or the initial purchase cost is higher, affecting the promotion of the market.

But the semiconductor lighting technology progress is rapid, the luminous efficiency of white LED has reached 60lm/W, while the NICHIA is a white LED claimed that by the end of 06 will be mass production of 100lm/W, T5 fluorescent lamp and the good performance of this data can be comparable, and before that, people expect the target code to achieve it in 2008. When the white LED into the general lighting market will have more advantages, to replace fluorescent lamps, energy-saving lamps will also become possible.

expectation

Semiconductor lighting as the third generation of lighting technology, and gradually become the mainstream of the field of lighting is an inevitable trend, the application of high-power LED in the field of indoor and outdoor lighting is the ultimate goal of its development. Together with the industry to explore these issues, the author believes that to improve the level of application of semiconductor lighting products, speed up the semiconductor
