In fact, the essence of the operation lamp is different from the ordinary lamp, which is to meet the special requirements of the operation：

1. Brightness requirements for operating room lighting,

2. Safe surgical lighting,

3. No shadow requirements,

4. Cold light requirements,

5. Removable disinfection requirements.

Surgical lights include two series of integral reflective operating lights and hole-type operating lights. Integral reflective operating lights have molecular mother lights and single lights; hole-type operating lights are also divided into two types: letter lights and single lights.

The operating light can guarantee the lighting brightness of the operating room. The surgeon in the operating room must be able to accurately distinguish the contour, color and movement. Therefore, the light intensity close to the quality of sunlight is required, and the light intensity is at least 100,000 illuminances. The operating light can provide the maximum brightness of a single lamp can reach 150,000 illuminances, and the brightness of the surgical lamp can be adjusted steplessly. In case of failure during the operation, the backup light bulb can be automatically switched for 0.3 seconds, so the surgical lamp can provide safe surgical lighting. The surgical lamp can meet the requirements of shadow-free lighting through the polygonal reflector. The reflective surface is formed by industrial stamping at one time, and the reflectivity is 95% higher, forming a homologous light beam, which is 80 cm from the lamp plate to form a beam deep into the surgical area to ensure surgery with high light level, no shadows, and remaining very even when the surgeon's shoulders, hands and head partially block the light source.

The surgical lamp is bright and avoids heat generation. The shadowless lamp can filter 99.5% of the infrared components through a new filter to ensure that the light reaching the operating area is cold light.

The shape design and installation position of the surgical light and the high standard sealing handle can effectively control the number of pathogens, and can be disassembled for disinfection.

For ceiling-mounted surgical lights, one or more transformers should be installed in the remote-control box on the ceiling or wall to convert the input mains voltage to the low voltage required by most bulbs. Most surgical lights have a dimming controller, and some products also adjust the light field range to reduce light around the surgical site (reflections and flashes from sheets, gauze, or instruments can be uncomfortable to the eyes). The operating light can ensure that the color temperature is as high as 4000 or more, which is close to sunlight, so that the color perceived by the eyes is clearer, and it will not cause the eyes of medical staff to be tired after working for a long time.
