When choosing the right hospital operating room lighting equipment, there are several key factors to consider:
1. Illumination requirements: the horizontal illumination of the general lighting in the operating room is not less than 500lx, and the new hospital is recommended to use 750-1500LX, and the vertical illumination is not less than 1/2 of the horizontal illumination. Operating table lighting usually uses a multi-sided mirror operating shadowless lamp, illuminance should be 20×10^3^ lx ~ 100×10^3^ lx.
2. Light source selection: It is recommended to use LED light source, because LED is a cold light source, there is almost no temperature rise in the room, and the patient has no uncomfortable feeling, while avoiding the risk of dehydration caused by light source irradiation, in addition, it can also appropriately reduce the energy consumption of indoor air conditioning; The color rendering of the general lighting source in the operating room should be close to natural light, and should be between 4000-5000K, usually the color rendering index Ra≥90.
3. Selection and installation of lamps: The selection and installation of operating room lighting lamps should pay attention to dust, water, corrosion resistance, high temperature resistance and other characteristics. The external shape of the lamp should be simple, not easy to accumulate dust, easy to wipe, generally do not use ordinary grille lamps, and the use of closed lamps with isolation cover, not only play a dust-proof effect, but also inhibit glare.
4. Limit stroboscopic and electromagnetic pollution: the light source should be strictly prohibited stroboscopic effect, because during the operation, surgeons and assistants often work in the dark field of vision for a long time, if the surgical lamp has stroboscopic, it will increase the visual burden of the operator, cause visual fatigue, and easily cause the operator to produce illusion and bring adverse consequences.
5. Color temperature selection: The color temperature of the operating room lighting should be selected to improve the visual comfort and accuracy of the surgical operation. In general, the color temperature should be between 4000K - 5000K to get close to the effect of natural light.
6. Avoid glare: Glare should be avoided in the lighting design of the operating room to reduce visual fatigue and interference. Therefore, the position and Angle of the lamp should be reasonably designed to avoid direct shooting into the surgical area.
7. Light source life and stability: the lighting equipment in the operating room should have a long life and stability to ensure the continuity and stability of the operation. Therefore, it is recommended to choose brands and models with reliable quality.
Our company independently developed and produced the latest shadowless lamp (petal model) MXLED700/500, has the above characteristics, the color index ≥96%, the average life of the lamp ≥ 60,000 hours, the center illumination and color temperature are adjustable, is now a third class hospital can use high-end products to ensure that the lighting needs during the operation are met. At the same time to ensure the safety and comfort of medical staff and patients.
