Abstract

The invention relates to medical illumination equipment, in particular to a shadowless lamp for use in an operation, more particular to an LED (light emitting diode) shadowless lamp. The LED shadowless lamp comprises a round lamp shell, wherein a plurality of LED lamp plates are arranged in the lamp shell; control circuits for LED lamps are arranged on the lamp plates; the LED lamps on the lamp plates comprise LED lamps with color temperature of 4000K and LED lamps with color temperature of 6500K; each lamp plate is provided with four rows of LED lamps, and one LED lamp, two LED lamps, three LED lamps and four LED lamps are uniformly arranged in sequence from the center of a sector to the outside; and the rows of LED lamps on the six lamp plates form four concentric circles in the lamp shell. According to the LED shadowless lamp provided by the invention, an LED lamp set is adopted; the power is low; the color temperature, the illuminance, the color development index and the like all meet the standards of the industry; and the lamp set has long service life and low manufacture cost, and has a certain value for promotion and application.

Description

technical field [0001] The invention relates to medical lighting equipment, in particular to a shadowless lamp used in operations, in particular to an LED shadowless lamp. Background technique [0002] At present, most shadowless lamps use halogen tungsten lamps as the light source, and use multiple small mirror reflection lampshades to form shadowless lamps. However, halogen tungsten lamps are thermal lamps, and the diameter of the spot is small and the light focus is shallow. The service life of the bulb is short, which is easy to cause visual fatigue. . LED lamps are cold light sources, which are very suitable for use in shadowless lamps. However, the light requirements of shadowless lamps in operating rooms are strict, and there are high requirements for color temperature, illuminance, and imaging index. However, the color rendering of LED lights is poor, the white light spectrum is narrow, and LED lights have the disadvantages of high color temperature, low imaging in...
