My points

What is LED ?

LED =Light Emitting Diode. Mainly by the bracket, silver plastic, chip wafer, gold wire, epoxy resin, five kinds of materials.

Convert electrical energy into light energy semiconductor. Direct issued by red, yellow, blue, green, blue, orange, purple, white light.

It is different from traditional energy-saving lamps using tricolor powder luminescence and incandescent lamps using tungsten light. It uses electric field emitting.

The classify of LED

Divided on luminous tube lighting color

Divided on luminous tube characteristic

Divided on angle from the the luminous intensity

Divided on constructor of lighting emitting diode

Discussion The pole lamp to light the way for the driver and the rider

with and increased brightness low lever lamps, as well as a pedestrian sidewalk.

The shade down irradiation lamps and lighting up on the sidewalk near the horizon the issue of diffuse light LED lights.

Lighting equipment in the manufacture lampshade should be able to control the lighting direction , so you can make the LED light is blocked, only just below the standing lamp was only shine get fired other direction.

The color temperature can be adjusted to different needs of the business district or residential areas.

Classify the use of the LED lights at night, allocated on a reasonable basis, depending on demand, daily power consumption.

In public places, try to use a lot the sensor LED lights, which can reduce the waste of energy.

Conclusion The pole lamp to light the way for the driver and the rider to

use the increased brightness low lever lamps, as well as sidewalk. Because LED lights glare too oppressive.

On the Shade down and lighting up on the sidewalk near the horizon using the irradiation lamps. It can solve the issue of diffuse light LED lights.

Lighting equipment in the manufacture lampshade should be able to control the lighting direction, so you can make the LED light is blocked, only just below the standing lamp was only shine get fired other direction.

The color temperature of the lamp can be adjusted to accommodate the different needs of the business district and residential areas.

Classify the use areas of the LED lights at night, allocated on a reasonable basis, depending on demand, daily power consumption.

In public places, try to use a lot the sensor LED lights, which can reduce the waste of energy.

Technology advances make the price of LED lights more civilians, operating principles and use more easily understood.
