Lamp holder assembly for high-power LED operation shadowless lamp

High-power LED surgical lampless lamp holder assembly, the lamp holder is installed with more than two sets of ring-shaped LED lamp groups along the axis of the shaft diameter, the light emitting surfaces of the LDE lamps on the adjacent two groups of ring-shaped LED lamp groups are set in error, and the lamp holder is installed There is a heat pipe. The light source of the utility model spreads to the periphery more evenly, and the optical dispersion formed by a plurality of LED light emitting surfaces is reflected by the reflector to synthesize a large-area light source, which increases the focus spot diameter and the illumination depth, and has a large color rendering index. Realistic and even distribution of gloss ensures the surgical field has sufficient brightness and the operator's eyes are not fatigued. This guarantees the quality of the operation. At the same time, the heat generated by the circular LED lamp group is rapidly transmitted to the lamp holder through the heat pipe and connected thereto. The components perform heat dissipation so as to effectively control the junction temperature of the high-power LED lamp so that the LED lamp can emit light normally and stably.
The utility model relates to a lamp holder assembly for a high-power LED operation shadowless lamp, which belongs to the technical field of surgical shadowless lamps.
BACKGROUND Surgical shadowless lamps are used to illuminate surgical sites. Traditional incandescent lamps use incandescent lamps or halogen lamps as light sources. However, incandescent or tungsten halogen lamps have low light efficiency and poor color rendering properties, and have a small focused spot diameter and a shallow focal length. short. Due to the above shortcomings, the operator's eyes are easily fatigued, which is not conducive to the quality of the operation. At the same time, during the operation of the patient, the heat generated by the shadowless lamp is likely to cause damage to the internal cellular tissues of the human body and is not conducive to the patient's recovery. The LED lamp is widely used because of its narrow spectrum, pure color, higher luminous efficiency, low power consumption, and long service life than an ordinary incandescent light source. At present, the more advanced surgical shadowless lamp adopts a light emitting diode as a light source, and a plurality of sets of light emitting diode units are mounted on a lamp shade, and the shadowless lamp of the surgical shadowless lamp is required by increasing the number of light sources. However, the shadowless lamp of the above structure still has the problems of small focal spot diameter, shallow light focus, and unclear observation of different depths of tissue. At the same time, since the light emitting diode itself generates heat during operation, the heat of the light emitting diode disposed on the light cover only depends on the natural convection of air to dissipate heat, resulting in poor heat dissipation performance, affecting the efficiency of the light emitting diode, and reducing the service life.
SUMMARY OF THE INVENTION The objective of the present invention is to provide a lamp holder assembly capable of increasing the focus spot diameter and the illumination depth, and having a good heat dissipating effect.
The technical scheme of the utility model to achieve the above object is: a lamp holder assembly of a high-power LED surgical shadowless lamp, characterized in that it comprises a lamp holder and a heat pipe, and the seat has more than two sets of ring LEDs installed along the axis of the shaft diameter. In the lamp group, the light emitting surfaces of the LDE lamps on the adjacent two groups of ring-shaped LED lamp groups are set in phase, and a heat pipe is installed on the lamp holder.
The utility model adopts more than two groups of annular LED lamp groups arranged along the axial direction, and the light emitting surfaces of the LDE lamps on the adjacent two groups of ring LED lamp groups are arranged in an opposite direction, not only the light sources spread to the periphery more uniformly, but also emit light through multiple LEDs. The surface formed optical dispersion/shop/infodetail.html?providerid=100015024749&ciid=3724535&psort=2 forms a large-area light source to illuminate the working area after the reflector has been reflected, increasing the focus spot diameter, the color rendering index, and the color temperature vivid luster. The distribution is even, so that the surgical field has enough brightness and the operator's eyes are not easily fatigued.
The two or more sets of ring-shaped LED lamps arranged along the axial direction of the utility model increase the depth of illumination of the shadowless lamp, so that the operator can better observe the internal tissues of different depths of the human body and ensure the operation quality. The utility model adopts more than two sets of annular L and ED lamp sets, which can play the role of main and auxiliary light sources, and does not need to switch operation of the auxiliary lights, and has a compact structure and reduces the volume of the shadowless lamp.
The utility model has a heat pipe installed on the lamp holder, and the heat generated by the ring L, ED lamp group is quickly transmitted to the lamp holder and the parts connected with the lamp holder through the heat pipe, and heat is transferred to the air through the heat dissipation surface of the lamp holder. Disperse in the middle, the structure is compact and reasonable, due to a significant increase in the heat transfer rate and heat dissipation area, so as to effectively control the junction temperature of high-power LED lamps, so that the LED lamp can light normally and stably. Due to the lower temperature in the work area, damage to the internal cellular tissues of the human body is reduced.
