Problems solved by technology
However, the shadowless lamp with the above structure still has the problem of small focus spot diameter and shallow light focus, which makes it difficult to observe tissues at different depths.
At the same time, because the light-emitting diode itself will generate heat when it is working, and the heat of the light-emitting diode arranged on the lampshade only relies on air convection to dissipate heat, so the heat dissipation performance is not good. Reduced service life

Embodiment Construction
[0015] See Figure 1~3 As shown, the LED surgical shadowless lamp of the present invention includes a housing 1, a hemispherical reflector 3, a light-transmitting cover 17, a lamp holder 6, and an LED lamp. The guide sleeve 1-1 is welded or installed. The guide sleeve 1-1 can adopt integral or split structure. The heat conduction strip 2 can be welded on the shell 1 or the guide sleeve 1-1, or the heat conduction strip 2 can be installed on the shell 1 and guide Between the sleeves 1-1, the shaft sleeve 6-1 on the upper part of the lamp holder 6 is installed in the guide sleeve 1-1 on the top of the shell 1 and can move axially. The heat is quickly and evenly transferred to the casing 1, and then dissipated outward through the casing 1, and the casing 1 is provided with a handle 18. See figure 2 , 3 As shown, the outer periphery of the 6-axis diameter of the lamp holder of the present invention is equipped with a ring-shaped LED lamp group 5. The ring-shaped LED lamp group...

The invention relates to an LED shadowless operating lamp which comprises an outer casing, a reflecting cover, a transmission cover and LED lamps, wherein the reflecting cover is in a hemispherical shape; the inner side of the outer casing is provided with heat conducting strips which form distributed shapes; a shaft sleeve on the upper part of a lamp seat is arranged in a guide sleeve at the topof the outer casing; an annular LED lamp group is arranged on the circumference of a lamp seat shaft diameter; middle heat pipes arranged in a lamp seat inner hole are connected with the guide sleeve; more than two outer heat pipes are arranged on the lamp seat; a fan seat provided with a fan is arranged on the bottom of lamp seat; the reflecting cover is positioned on the upper part of the annular LED lamp group; the outer casing and the reflecting cover are connected with the transmission cover; a radiating space is arranged between the reflecting cover and the outer casing; a connecting seat is supported on the transmission cover; and an adjustment rod connected with the fan seat passes through the connecting seat to be connected with an adjustment handle. The invention can increase focusing spot diameter and lighting depth, has compact structure, large color rendering index, living color temperature, uniform gloss distribution and good radiating effect, effectively controls the junction temperature of the LED lamp with large power, and ensures that the LED lamp can normally and stably emit light.
Description
technical field [0001] The invention relates to an LED surgical shadowless lamp, which belongs to the technical field of surgical shadowless lamps. Background technique [0002] The surgical shadowless lamp is used to illuminate the surgical site. 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 operator's eyes are prone to fatigue, which is not conducive to the quality of surgery. 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 are widely used because of their narrow spectrum, pure light color, higher luminous efficiency than ordinary incandescent...
