Abstract

The utility model discloses a portable LED (light-emitting diode) shadowless lamp and relates to the technical field of production of medical devices, namely shadowless lamps for operations. The portable LED shadowless lamp comprises an aluminum-titanium alloy lamp holder. A circuit board is welded on one side surface of the lamp holder and a plurality of LED lamp caps are arranged on the circuit board. The portable LED shadowless lamp can eliminate complex production process of arranging a plurality of lamp holder holes in the lamp holder and further arranging LED lamp cap components in all the lamp holder holes, is good in direct heat dissipation performance, conducive to further reducing light decay, and long in service life of an LED; simultaneously, as the direct irradiation is adopted, the reflection is avoided, the luminous efficiency is high, a focusing system does not need to be mounted, and materials can be saved to the greatest extent, so that the whole shadowless lamp becomes more portable is conductive to further proceeding of an aseptic operation.

Description

A kind of lightweight LED shadowless lamp

Technical field

The utility model relates to technical field of medical instruments, particularly the operation production technical field of shadowless lamp.

Background technology

Shadowless lamp is one of most important Medical Devices of operating room, and medical personnel are implemented in the patient and execute art position shadow-free illumination purposes by the use of shadowless lamp, thereby helps the doctor clearly to differentiate lesion tissue, successfully finishes operation.

Existing shadowless lamp all is to adopt many incandescent lamps or Halogen lamp LED to be combined on the lamp socket, can produce a large amount of infra-red radiations, and Metal halogen lamp also has certain ultra-violet radiation.Shine excessive ultraviolet ray, can produce injury human body.Infra-red radiation can cause surface of a wound temperature to raise, and quickens the blood clotting of patient's wound, and what be unfavorable for performing the operation normally carries out, and also can produce hot sense to doctor and nurse, is unfavorable for that operation normally carries out.In addition,, do not seem so yellow, generally by expensive optical filtering measure, make colour temperature bring up to about 4400K, but nonetheless, it is unnatural that light still seems in order to make light because of the intrinsic colour temperature of halogen tungsten lamp approximately is 3200K.Because of service life of halogen tungsten lamp short, need more change the bulb continually, cost height has not only increased medical personnel's working strength, as taking place in operation, has then directly influenced lighting effect, what be unfavorable for performing the operation carries out smoothly.In addition, the light source of traditional shadowless lamp needs mains-supplied, and its stand-by power supply needs complicated inversion system, with the power supply of battery dc low-voltage, be converted into the civil power of ac high voltage, has not only increased the complexity of cost, system, has also increased security risk.More crucial is, no matter which kind of existing light source all has stroboscopic, can increase medical personnel's asthenopia, is unfavorable for the carrying out of prolonged operations.

Summary of the invention

The utility model purpose is to design a kind of low cost that can overcome the prior art defective, life-span length, no stroboscopic, radiationless lightweight LED shadowless lamp.

The utility model comprises the aluminum titanium alloy lamp socket, at a side soldered circuit board of described lamp socket, arranges some LED lamp holders on described circuit board.

The utility model has been removed and offered some lamp sockets hole on lamp socket, numerous and diverse production technology of LED lamp adapter assembly is set in each lamp socket hole again, directly thermal diffusivity is good, be beneficial to and further reduce light decay, improve the service life of LED, simultaneously, owing to adopt direct irradiation, areflexia, the luminous efficiency height need not to install focusing system, is beneficial to greatly economical with materials, make whole shadowless lamp lighter, be beneficial to the carrying out of further asepticize operation, it is good also to have light quality simultaneously, doctor's head and patient's wound area almost do not have temperature rise, no stroboscopic, life-span is long, environmental protection, low energy consumption, the advantage of the radiation pollution of no infrared and ultraviolet composition meets the requirement of the whole green illumination of current hospital, in addition, the spatial distribution of led light source has also determined it to be suitable as very much the light source of operation shadowless lamp.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model is provided with the aluminum titanium alloy lamp socket 1 that is beneficial to moulding, at the downside soldered circuit board 2 of lamp socket 1, arranges some LED lamp holders 3 on circuit board 2.

Claims

1. a lightweight LED shadowless lamp is characterized in that comprising the aluminum titanium alloy lamp socket, at a side soldered circuit board of described lamp socket, arranges some LED lamp holders on described circuit board.
