Medical lighting device

Abstract

The invention discloses a medical lighting device, comprising: a supporting frame; a plurality of LED light sources arranged on the supporting frame; The lens focuses the light emitted by the multiple LED light sources towards the target location. The medical lighting device improves the utilization rate of the light emitted by the light source, and provides a multi-layered illuminated surface and an ideal surgical lighting space. The optical path structure of medical lighting equipment is simplified, and the volume of medical lighting is reduced while satisfying the function of reducing the shadow of the illuminated object, making it easier for clean air to reach the surgical wound site, eliminating the need for participation in medical activities. Risk of injury to personnel (doctors performing surgical activities, etc.)

Description

technical field [0001] The invention relates to the field of medical lighting, in particular to a medical lighting device. Background technique [0002] In medical activities (surgery), the lighting requirements for medical lighting equipment are different from those for general lighting equipment. Medical lighting equipment must not only provide illumination for the area where medical activities (surgery) is being performed, but also have weakened light for irradiation The function of the shadow of the illuminated object produced by the illuminated object, and provide a three-dimensional area with consistent illuminance, color rendering index, and color temperature. [0003] In the existing medical lighting equipment used for medical activities (surgery), in order to project light onto the irradiation surface from different angles in this equipment, so as to achieve the effect of weakening the shadow, the light-emitting point is set on a spherical arc surface. The illumina...

Problems solved by technology

Since the illuminated surface 4' is the superposition of various light sources, the illumination depth is very poor

In addition, while the halogen bulb 2' emits visible light, it also emits infrared rays that greatly increase the temperature of the object, while the filter 3' can only filter out part of the infrared rays, and part of the infrared rays still reach the illuminated surface through the reflector 1' 4', resulting in an increase in temperature at 4' of the illuminated surface

When performing medical activities (surgery), it is necessary to lower the temperature of the wound site to prolong the survival of the wound tissue. However, the existing medical lighting equipment will inevitably cause the temperature of the 4' of the illuminated surface to rise, which will increase the temperature of the wound. , which would harm the patient

[0006] At the same time, using the figure 1 The medical lighting equipment with the structure shown in , since there is only one reflector 1' and one light source 2', all the illumination light is reflected from the light source 2' from one reflector 1', and the illuminated surface 4' of the reflector has only one , so that it cannot provide an ideal spatial area with consistent illuminance, color rendering index, and color temperature

[0007] in addition, figure 1 The reflector of the medical lighting equipment shown in the structure is very large, resulting in a large volume of the medical lighting equipment. When used for medical activity (lighting) lighting, it will prevent clean air from reaching the surgical wound site, and it is easy to damage the personnel involved in medical activities. (doctors performing surgical activities, etc.) causing injury
