LED (light-emitting diode) operating lamp with adjustable size and shape of lighting faculae

Abstract

The invention discloses an LED (light-emitting diode) operating lamp adjusting the size and the shape of a lighting facula. The operating lamp is composed of a main lighting light source and an auxiliary lighting light source, wherein the two part light sources are realized through an LED array, the main lighting light source is divided into six regions which are respectively defined as W0,W1,W2,W3,W4 and W5; the auxiliary lighting light source is divided into two regions which are respectively defined as V1 and V2, each region is internally provided with a group of LED monomers, whether each group of LED monomers is lightened is controlled by a singlechip through a relay, and combinations of different regions form different sizes and shapes of irradiation faculae; and the main lighting light source and the auxiliary lighting light source also can realize adjustment of the lighting angle of a light source respectively through an angle adjusting mechanism, and the LED operating lamp realizes the control of switching-on and switching-off of a power switch, the size and shape of the main lighting or auxiliary lighting faculae size and the lighting angle through a key state on the control panel. Users adjust the required lighting effects through a control button according to the real lighting field requirement.

Description

Technical field [0001] The invention relates to an LED shadowless lamp for clinical operation lighting, which belongs to the field of medical equipment. Background technique [0002] LED lights have excellent characteristics such as long life, low energy consumption, and fast start-up, and are more and more widely used in signal lights, lighting sources, graphics and image display and other fields. [0003] Conventional surgical shadowless light sources generally use high temperature light sources such as tungsten filament lamps, and the temperature under the lamp is generally about 10 degrees higher than the ambient temperature. In this way, the moisture on the exposed human tissue is easily evaporated, and dehydration of the human tissue is not conducive to the recovery of the patient after surgery, and also affects the physical condition of the surgeon. [0004] Conventional surgical lamps need to be equipped with special optical lenses in front of the lampshade to make the emitt...

Problems solved by technology

In this way, the water on the exposed human tissue is easily evaporated, and the dehydration of human tissue is not conducive to the post-operative recovery of the patient, and also affects the physical condition of the surgeon.

[0004] Conventional surgical lights need to install a special optical lens in front of the lampshade to make the emitted light uniform, which not only costs a lot, but also increases the quality of the surgical lamp, and it is also difficult to maintain
