LED light source with the use of
low-voltage power supply, consuming less applicability, high stability,
response time is short, environmental pollution, such as the advantages
of multi-color light-emitting, although more expensive than the
existing lighting equipment expensive, is still considered that it will
not be Avoid to replace the existing lighting devices. At present, LED
light efficiency of up to 100 lumens / W by 2015, when, LED light
efficiency is expected to reach 150 ~ 300 lumens / watt. At that time
the work of white LED current can Daan Pei-level. White LED light
source at 5500K color temperature around it than the xenon light source
(4000K) closer to natural light (6000K). In addition, LED also has a
short response time, the same light source can be realized two
functions (such as beam lights and daytime running lights can be shared
light source), design styles and diverse characteristics of a flexible,
low power consumption, to achieve the same brightness of traditional
light bulb, the power consumption of only 6% of conventional bulbs,
energy-saving fuel-efficient, LED lamps in the field of automobile
production have great potential for development. While an ordinary
incandescent and halogen lighting though inexpensive, but the luminous
efficiency is low (thermal effect of light power in vain), and short
life span, maintenance workload, but with the white LED for
illumination, not only the high luminous efficiency, and the long life
(100,000 hours continuous working time and above), almost no
maintenance.
