LED shadowless desk lamp for operation

Abstract

The invention discloses an LED shadowless desk lamp for an operation. The LED shadowless desk lamp comprises a lampshade (1), a light transmitting cover (2), integrated LED units (3), an adjusting controller (4) for controlling the light intensity and light spots of the integrated LED units as well as a position adjusting bracket (5), wherein the lampshade (1) adopts a spherical surface; the number of the integrated LED units (3) is at least one and the integrated LED units (3) are downwards concaved to form spherical surfaces; the integrated LED units (3) are mounted at the top of the position adjusting bracket (5); the light intensity and light spot adjusting controller (4) is mounted on the position adjusting bracket (5) and is positioned below the LED units (3). The LED is used as a luminous body; no strobe appears, so eye fatigue does not easily caused, or harmonic interference to other devices in a working area is avoided; an LED shadowless cold light source uniformly irradiates by 180 degrees; the integrated LED units hardly generate the heat and are not easy to crack, so potential safety hazards are thoroughly eliminated.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED operation shadowless lamp. Background technique [0002] Surgical shadowless lamps are routine and necessary equipment in hospital operating rooms, and the use of surgical shadowless lamps is a necessary working condition and prerequisite for many surgical operations. Traditional shadowless lamps use incandescent lamps or tungsten-halogen lamps as light sources, but incandescent lamps or tungsten-halogen lamps have low light efficiency, poor color rendering, small focus spot diameter, shallow light focus, and short service life. Due to the above shortcomings, the eyes of the operator are prone to fatigue, which is not conducive to the quality of the operation. At the same time, during the patient's operation, the heat generated by the shadowless lamp will cause great damage to the internal cells and tissues of the human body, which is not conducive to the patient's recovery. LED lamps a...

AI Technical Summary

Problems solved by technology

At present, the shadowless lamp used in the operating room of the hospital is composed of an umbrella-shaped lamp shell and a group of halogen bulbs to form a whole lamp head, and is installed on the roof of the operating room by a Y-shaped tube, a straight tube, a cross-arm tube, and a fixing seat. There are many shortcomings in design and application, such as high temperature, uneven brightness at the center spot, high power, large color difference, no technical requirements for color fidelity, failure to meet the requirements of vertical and horizontal air laminar flow, small range of activities, and unsuitable Use in high-demand clean operating rooms, etc., which affects the quality of surgery
