LED applications are becoming more diversified into architecture, entertainment, gardening and other fields

Ordinary white fluorescent lamp suitable for daily lighting and back lighting, and color LED can achieve its application in architecture, such as entertainment and gardening fields. Shanxi Music Technology Co., Ltd. announced its new green LED LED (150~160lm), while Philips Lumileds in its Luxeon series also added a new deep red.

Luxeon RebEL LED Philips series color ranging from blue (440-460nm) to red (650-670nm) color. The recent launch of the crimson LED aims to build applications in the fields of horticulture and entertainment. In addition, Philips announced that some government departments also need to install its own railway and road signals deep red LED.

Deep red LED in safety facilities and Horticulture

Different from standard red (620-645nm), deep red LED has a higher visibility. Philips estimated that this LED drive current is about two times the normal Luxeon series. In the case of 700mA, this LED generates 720mW radiation power or radiation flux.

"In the past ten years, Luxeon LED has become an active atmosphere for the construction of city, add luster to the protagonist; LED also add artistic atmosphere for all kinds of performing arts activities; ensure people's daily travel traffic safety. We are committed to continuously improving the quality of our color LED series and improving the light output. Steve senior vice president of marketing, said Barlow.

Gardening is the main purchasing power of dark red LED. We in the LED-based horticultural lighting has pointed out, in the 660nm wavelength of chlorophyll synthesis rate reached the highest. Plant cultures and greenhouses are replacing common lighting with a single wavelength light source. Osram introduced LED to the field last year.

Another special color LuxeonLED is the product of the blue LED. It also achieves 1120mW radiation power at 700mA. It mainly uses LED and phosphor separation technology to achieve ordinary lighting function. Philips earlier this year released its own product blue LED. It is also mentioned in a news report Cree released his own product blue LED news.

Brighter green LED

Green LED, was due to charge separation effect in the aspects of lumen output which has been questioned, the green LED of the Rensselaer Polytechnic Institute Industrial Institute and other research institutions, has been committed to the brighter. China Shanxi Le hundred technology company has claimed to have produced 350mA drive current under the green LED 150-160lm. If the company can produce the product under the premise of good cost benefit. It will be a leading position in special applications such as general lighting, backlighting and gardening.

Large screen TV backlight can be improved by using RGB (red, green and LED) to improve the color saturation of the blue. But many TV producers have used RGB mode, because they need 2 sets of green LED and a group of red and blue LED to reconcile the brightness consistent from beginning to end in the same way, general lighting equipment; RGB mode can achieve color. But at present, the green LED on the market can not meet the requirements.
