There are three main types of surgical lights. They are hole type shadowless lamp, overall reflection shadowless lamp, and LED shadowless lamp
1. Hole-type shadowless lamp: It has a great price advantage, and there is still market demand in some underdeveloped areas.
2. Overall reflection shadowless lamp: high luminous efficiency, can obtain ideal brightness, color temperature and luminous efficiency. Compared with hole type shadowless lamp and LED shadowless lamp, its shadowless effect is the best.
3. LED shadowless lamp: LED is a cold light source, and the illumination of infrared and ultraviolet rays is extremely low. It has 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 and uneven light emission.
2. Overall reflection shadowless lamp: higher temperature rise and energy consumption.
