Future development trend of green lighting technology

[for green lighting posters]

The next 20 years, the development of electric light source technology will continue to improve the performance and technical parameters of the main direction of development. Key areas of technology are still in:

To improve the efficiency of light, the next gas discharge lamp light effect will be more than 100lm/W, high intensity discharge lamp (HID) light efficiency will be higher, incandescent light source through a variety of technical innovations have also further improve the luminous efficiency of incandescent lamp, so completely in a short time is not easy.

To improve the performance of color: most of the future of the color rendering index will exceed 80, fluorescent lamps will be widely used in the fluorescent powder of the three primary colors.

Improve the service life: gas discharge lamp life of more than 1000 hours, there will be a variety of longer life of new light source.

The effect of environmental protection and improve the visual effect of light source production will pay more attention to reduce harmful substances, such as discharge lamp for research and development of less mercury and mercury free fluorescent lamp, narrow diameter and improved phosphor coating process, to reduce the amount of fluorescent powder; the further development of high frequency fluorescent lamp and DC fluorescent lamp, improve the light stability, eliminate the stroboscopic effect, reduce electromagnetic radiation, noise elimination etc..
