1. First of all, the important point is to have sufficient illuminance. The illuminance of the surgical shadowless lamp can reach more than 150,000 LUX. This illuminance is close to the brightness under the sun under sunny conditions in summer, and the actual illuminance is generally 40,000 to 100,000 LUX. To be suitable, too bright will affect eyesight. While providing sufficient illuminance, the surgical shadowless lamp should also prevent the beam from glare on the surgical instruments.

2. Secondly, the shadowlessness of the surgical shadowless lamp should be high, and the shadowlessness is an important feature and performance index of the surgical shadowless lamp. Any shadow formed in the surgical field of vision will hinder the doctor’s observation, judgment and operation. A good surgical shadowless lamp should not only provide sufficient illumination, but also have a high degree of shadowlessness to ensure that the surface of the surgical field of view and the deep tissues are comparable. Luminosity.

3. Thirdly, the temperature generated by the surgical shadowless lamp should be very low to prevent affecting the quality of the operation. Generally, the increase of the illuminance of the surgical shadowless lamp will cause the lamp body and the operation quality of the surgical shadowless lamp.

4. Under normal circumstances, the temperature of the operating room should be controlled within 10°C. The main way to achieve this effect is to pass the visible light generated by the surgical shadowless light source through a mirror that can filter out 70% of the infrared, and the remaining infrared will be The light beam that is isolated and filtered by the glass cover and processed by the above-mentioned method is called cold light.

5. The light quality of the surgical shadowless lamp is better. The so-called good light quality means that the light beam provided by the surgical shadowless lamp can truly reflect the color and change of blood and tissue. This performance is generally called color rendering, which is It is expressed by the color rendering index value calculated from the light distribution of the light source, and the color rendering index is 100.
