What`s the LED light?
LED is abbreviation of Light Emitting Diode, it is a new technology
developed the middle of the 20th century. It is direct light relies on the
electrons of semiconductor heterojunction removed by barrier energy. The light
produced by LED is luminescence process which does not generate heat, the energy conversion efficiency is close to one
hundred percent, long service life, and the LED light is the continuous
development of lighting technology direction.
LED light-emitting
principle
Light-emitting diodes (led)
core part is composed of p-type and n-type semiconductor chips, between the
p-type and n-type semiconductor has a transition layer, called the p-n
junction. In some of the semiconductor PN
junction, the minority carrier injection compound with majority carrier will
release excess energy in the form of light, so as to directly convert the
electric energy to light energy. PN junction to add reverse
voltage, and minority carrier injection, so don't shine.
Advantages of LED lamp
(light):
Voltage: LED light use
the low voltage power supply, single voltage between 1.9-4v, safer than using
high voltage power supply of the power supply.
Effectiveness: high
light efficiency. In the laboratory the photosynthetic efficiency has reached
161lm/w (Cree), it is the highest photosynthetic efficiency in all lighting
products.
Vibration resistance:
LED is a solid-state light source, because of its particularity, the
shock-resistant which other light source products can't compare with.
Stability: 100000 hours,
droop for 70% of the original.
Response time: the
response time of the LED Lights in nanoseconds, it is currently the fastest
response time of all the light source products.
Environmental
protection: no mercury and other harmful substances.
Color: the LED ribbon is
quite narrow, light color pure, no variegated light, covering the whole visible
light of the full band, and can be combined by the R\G\B into any want to
visible light.
Now the LED light have
been widely applied to Auto lamp, LED road light, LED street right, LED square lamp, Led Tunnel Lamp, LED Garden lamp, LED
Corridor lamp, LED Mining Light, LED table lamp, LED landscape lighting and LED screens.
The some types LED lights my factory has produced as follow:
