1. Hole type shadowless lamp: It has a large price advantage, and there are still market demand in some underdeveloped areas.
2. Integral reflection shadowless lamp: high luminous efficiency, can obtain ideal brightness, color temperature and luminous efficiency; compared with the hole type shadowless lamp and LED shadowless lamp, its shadowless effect is the best.
3. LED shadowless lamp: LED is a cold light source, the infrared and ultraviolet light have very low illumination, and have the advantages of low voltage, low energy consumption, long life, strong applicability, high stability and short response time.
1. Hole type shadowless lamp: low luminous intensity, uneven illumination.
2. Integral reflection shadowless lamp: high temperature rise and high energy consumption.
