In
recent years, LED technology with the development of high brightness,
the overall size of the market was fairly rapid growth, especially the
white LED market size of the expansion is even more evident, so the
development of new uses white LED is also continuous. In order to
expand, especially LED white LED applications, how to improve
luminescence efficiency, the corresponding luminance and prolong life
and reduce the cost per unit of lighting conditions. In order to
expand, especially LED white LED applications, how to improve
luminescence efficiency, the corresponding luminance and prolong life
and reduce the cost per unit of lighting conditions. Now use white LED
luminous efficiency, in addition to part of the products, the most in
30 ~ 50lm / W or so. Now use white LED luminous efficiency, in addition
to part of the products, the most in 30 ~ 50lm / W or so. So if you
want to Sunburn light instead of white light on the need to be raised
to 70 ~ 80lm / W or more, if you want to instead of using the car
headlights on the HID and home lighting would be even more necessary to
100lm / W or more luminous efficiency. So if you want to Sunburn light
instead of white light on the need to be raised to 70 ~ 80lm / W or
more, if you want to instead of using the car headlights on the HID and
home lighting would be even more necessary to 100lm / W or more
luminous efficiency.

| Compared to
incandescent bulbs, fluorescent and other light sources, LED
semiconductor components, do not use tungsten wire or glass,
anti-vibration causes the component service life longer. LED small
size, light color control is easy, easy to meet the needs of
applications made little or array-type modules can be achieved in the
past does not have lighting design. LED spectral concentration of
visible light, will not be generated according to body injury, another
substantial increase in recent years, LED luminous efficiency, 2009,
Nichia announced at the laboratory to develop the efficiency of the
light to reach 249 lm / W white LED, the commercialization level of is
also up to 150 lm / W or so, far higher than incandescent or
fluorescent lamps, light-emitting efficiency of the higher potential
for higher energy efficiency. In 2008 the world's light-emitting diode
market size of 67 billion dollars. Looking to the future development,
and general lighting, automotive, display backlight will be the key to
driving growth in their markets. |
