Disadvantages of LED light
1. Attention should be paid to heat dissipation. If the heat dissipation is not good, the service life will be greatly shortened.
2. The power saving performance of low-end LED lamp is lower than that of energy-saving lamp.
3. The initial purchase cost is high.
4. Due to the strong directivity of LED light source, the special optical characteristics of LED should be considered in lamp design.
Advantages of LED light
1. Good environmental protection: it is a new type of green light source, with better environmental protection benefits. There is no ultraviolet and infrared in the spectrum, and the waste can be recycled, no pollution, no mercury, and can be safely touched. It is a typical green lighting source. At the same time, led uses cold light source, which has small glare and no radiation.
2. Long life: LED is a solid cold light source, encapsulated in epoxy resin, anti vibration, no loose part in the lamp body, no filament burning, heat deposition, light decay and other shortcomings, the service life can reach 60000-100000 hours, more than 10 times of the service life of traditional light source.
3. Multi transform: the light and color of LED combination are changeable, which can achieve rich and colorful dynamic change effect and various images.
