The advantages and disadvantages of LED lights
Jun 07, 2018


New green and environment-friendly light source: LED USES cold light source, small glare, no radiation, no harmful substances produced in use. The working power of LED is low, using dc drive mode, ultra-low power consumption (single tube 0.03~0.06W), electro-optical power conversion is close to 100%, saving more than 80% more energy than traditional light source under the same lighting effect.

LED the environmental benefits of better, no ultraviolet and infrared spectrum, and waste recycling, no pollution, no mercury elements, can safely touch, belongs to typical green lighting source.

Long life: LED solid cold light source, epoxy resin encapsulation, shock resistant, no loose parts in the body, there is no filament light easy to burn and thermal deposition, droop, such as faults, service life can reach 60000 ~ 100000 hours, is a more than 10 times the service life of the traditional light source. LED performance is stable, can be in - 30 ~ 50 ° C + normal work environment.

Multiple transformation: LED light source available red, green, blue three colors principle, in under the control of computer technology make the three colors gray level 256 and arbitrary mixed, can produce 256 x256x256 (16777216) colors, forming different color combinations. LED combination of light and color changes many end, can achieve a variety of dynamic change effects and various images.


Heat dissipation problem, if poor heat dissipation will greatly shorten the life.

Low - end LED lights are still less efficient than energy - saving lamps (cold cathode tubes, CCFL).

Initial purchase costs are high.

Because of the strong directional LED light source, the special optical characteristics of LED need to be considered in lamp design.
