White light light-emitting diode (LED) shadowless lamp

Abstract

A white light light-emitting diode (LED) shadowless lamp relates to the technical field of medical equipment, in particular to the technical field of production of the shadowless lamp for operations. The white light LED shadowless lamp comprises a lamp base, wherein a plurality of groups of connection seats are arranged on the lamp base, and a group of whit light LED assemblies is respectively arranged in each connection seat. The white light LED shadowless lamp has the advantages of being long in service life, environment-friendly and low in energy consumption, and meets requirements of hospitals for integral environment-friendly lighting now days.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to the technical field of production of shadowless lamps for operations. Background technique [0002] The shadowless lamp is one of the most important medical equipment in the operating room. Through the use of the shadowless lamp, the medical staff can achieve the purpose of shadowless lighting on the patient's operation site, so as to help the doctor clearly distinguish the lesion tissue and complete the operation smoothly. [0003] Existing shadowless lamps all use multiple incandescent lamps or halogen lamps combined on a lamp holder, which will generate a large amount of infrared radiation, and metal halide lamps also have a certain amount of ultraviolet radiation. Exposure to excessive ultraviolet rays can cause harm to the human body. Infrared radiation will cause the temperature of the wound to rise and accelerate the blood coagulation of the patient's wound, w...

AI Technical Summary

Problems solved by technology

Infrared radiation will cause the temperature of the wound to rise and accelerate the blood coagulation of the patient's wound, which is not conducive to the normal operation of the operation. It will also cause a hot feeling to the doctors and nurses, which is not conducive to the normal operation of the operation.

In addition, because the inherent color temperature of tungsten-halogen lamps is about 3200K, in order to make the light less yellow, the color temperature is generally increased to about 4400K through high-cost filtering measures, but even so, the light still looks unnatural

Due to the short service life of tungsten-halogen lamps, frequent replacement of bulbs is required, which is not only costly, but also does not increase the work intensity of medical staff. If it occurs during surgery, it will directly affect the lighting effect, which is not conducive to the smooth progress of the operation.

In addition, the light source of the traditional shadowless lamp needs mains power supply, and its backup power needs a complex inverter system to convert the DC low-voltage power supply of the battery into AC high-voltage mains power, which not only increases the cost and complexity of the system, but also increases safety. risk

More importantly, no matter the current light source has strobe, it will increase the visual fatigue of medical staff, which is not conducive to long-term surgery.
