1 case
Some time ago, the inspection was carried out in a famous general hospital in Beijing. This is a well-known hospital with a history of 100 years and ranks among the top three in the country. When doing a full-body bone scan, I found that lighting has a very serious problem. Lying flat on the small bed of the scanning instrument, the bare fluorescent tube on the top of the head is directly into your eyes without any obstruction or pain. When the head enters the device, the light is blocked by the device and it is finally comfortable. But as the cot moves, suddenly the damn light plunges into your eyes. Imagine that the patient itself is relatively fragile due to the disease, and is more irritated by the stimulation of strong light. Such lighting should be changed!
There are similar situations in nuclear magnetic, CT and other examination rooms, which need to be taken seriously!
2 Specifications
Looking through the relevant norms in China, we pay more attention to the indicators of lighting in such places, such as illumination, illumination uniformity, color temperature, color rendering index, etc. There are not many regulations on lighting mode or lighting design, and the requirements are obviously unknown.
(quoted from "Code for Electrical Design of Medical Buildings" JGJ 312-2013)
3 practices
According to Article 8.2.5 of JGJ 312-2013 of the Electrical Design Code for Medical Buildings, medical building lighting should avoid direct glare interference to patients and those with fine visual medical operations. Obviously, the above cases do not comply with the provisions of this article.
How to meet the requirements of this article? The author suggests the following:
1. Adopt LED panel light, which can meet the requirements of illumination and other indicators, and can obtain soft light, both of which have both;
2, using a matte or similar lampshade to reduce the effects of glare;
3. Use indirect lighting.
Schemes 2 and 3 will reduce efficiency; preferred option 1 is more economical, feasible, and reasonable.
