First, led lamp advantages

1, environmental protection: is a new green environmental protection light source, environmental protection benefit is better, there is no ultraviolet and infrared spectrum, and the waste can be recycled, no pollution, no mercury elements, can be touched safely, belongs to the typical green lighting source. At the same time, LED uses cold light source, small glare, no radiation.

2, long life: LED for solid cold light source, epoxy resin packaging, vibration resistance, no loose part of the lamp body, there is no filament light burning, thermal deposition, light decay and other shortcomings, the service life can reach 60,000-100,000 hours, is more than 10 times the service life of the traditional light source.

3, multi-transformation: LED combination of light and color changes, can achieve rich and colorful dynamic change effect and various images.

Two, LED lamp shortcomings

1, heat dissipation should be paid attention to, if the heat dissipation is poor, the life will be greatly shortened.

2. Low-end LED lamps have lower power saving than CFLS.

3, the initial purchase cost is high.

4. Due to the strong directivity of LED light source, special optical characteristics of LED should be considered in lamp design.
