手术无影灯是一种十分重要的手术照明设备。随着医学事业的发展,临床手术对无影灯提出了新的要求。这些要求主要是:一、具有充足的照度。无影灯的照度已可达150000勒克斯以上,接近夏季晴天阳光下的亮度。实际使用的照度一般以40000～100000勒克斯为宜,过亮会影响视力。在提供充足照度的同时,应避免光束在手术器械上产生眩光。眩光影响视力和视觉,易使眼 Surgical shadowless lamp is a very important surgical lighting. With the development of medical science, clinical surgery put forward new requirements for shadowless lamp. These requirements are mainly: First, have sufficient illumination. Shadowless lamp illumination has reached more than 150,000 lux, close to the brightness of sunny summer sunshine. The actual use of illumination generally 40000 ~ 100000 lux is appropriate, too bright will affect vision. While providing adequate illumination, avoid glare from the beam on the surgical instruments. Glare affects vision and vision, making eye easy
