Traditionally, these systems have used mercury lamps
to supply UVC energy for disinfection.
Among those, the most dynamic and important market is clearly the UV curing business where UV LEDs definitely compete with traditional mercury lamps
and offer significant advantages in terms of cost of ownership, system miniaturization:
Unlike mercury lamps
, which produce unflattering light with a blueish-green tint, GL-SP07 LED floodlights shine cool, white light.
With Mitsubishi's existing lineup of rear projection TVs, light from a mercury lamp
-- installed in the rear section -- is split up into red, blue and green to create images on the front screen.
Thanks to compactness, lower cost of ownership and environmentally friendly composition, UV LEDs have started and will continue to replace traditional mercury lamps
in current applications, and will also open many new applications, especially portable ones.
The energy sources for UV or visible light cure are typically medium pressure mercury lamps
, pulsed xenon lamps, LEDs or lasers.
The other 25 percent have adopted UV disinfection systems, but these systems use mercury lamps
in direct contact with water.
Special lamps: halogen tungsten lamp, high pressure sodium lamp, high pressure mercury lamp
, metal halide lamp, photoflash lamp, spotlight, electric discharge lamp, arc lamp and ultraviolet and infrared ray lamps etc.
The PhlatLight LED PT-120 chipset is designed specifically for home theater projectors and contains a red, green and blue LED and offers instant start up without the warm-up and cool-down period required by today's conventional mercury lamp
Like other PhlatLight LED products, the PT-121 offers instant start up with no warm up and cool down period required by today's conventional mercury lamp
77:1 , Light Source Type Ultra High Pressure Mercury Lamp
, Wattage: 210 W, Screen Size:- 30 Inch To 300 Inch Measured Diagonally .
Virtually all micro display-based projection systems built to date have used a lamp such as the UHP or other ultra-high pressure mercury lamp
as a light source.
