Embodiment Construction

[0020] Specific embodiment 1 of the present invention, as figure 1 As shown, a medical LED lighting device includes an LED light source 4, and the LED light source 4 is installed in an entity package 1 integrally formed by PMMA (polymethyl methacrylate) plastic transparent material, and a part of the entity 1 is extended to form an optical path output End 3, the diameter of the output end 3 of the optical path gradually decreases along the output direction, and the outer side of the entity 1 can be covered with a reflective layer 5, so as to converge the light to the end of the output end 3 of the optical path for output as much as possible.

[0021] In the above embodiments, in order to improve the heat dissipation conditions of the LED light source 4 , a copper heat sink can be installed on the back of the LED light source 4 , and the heat sink can be extended out of the outer surface of the housing 1 .

[0022] On the basis of the above-mentioned embodiments, the battery fo...

Abstract

The invention discloses a medical light-emitting diode (LED) lighting device. The medical LED lighting device comprises an LED light source and is characterized in that the LED light source is installed inside an entity packaging integrally formed by transparent materials, one portion of the entity extends outwards and forms a light path output end, the diameter of the light path output end is decreased along an output direction, and a light reflection layer is coated outside the entity. The medical LED lighting device has the advantages that the size of the lighting device can be small, operation of the lighting device is convenient, light given out by the LED is transported and reflected inside a light-guide fibre material instead of being reflected in different medium materials, and therefore sufficient light intensity can be led to a local position and sufficient lighting can be formed on the position. Meanwhile, the whole device is simple in structure and low in manufacture cost.

Description

technical field [0001] The invention relates to medical equipment, in particular to a medical LED lighting device for eye surgery. Background technique [0002] In the process of ophthalmic medical surgery, it is necessary to illuminate the local position. The lighting method of the prior art usually uses optical fiber to introduce the light emitted by the high-power light source to the part that needs to be illuminated for illumination. The equipment used in this method is complicated to connect and has a large volume. , inconvenient to operate, and the equipment is relatively expensive. People are more inclined to use portable lighting equipment for lighting. Similar lighting equipment structures are disclosed in Chinese invention patent 200820046975.8, which includes a light cylinder body, a driver LED light source and heat dissipation in the light cylinder body. The body also includes an optical fiber and a concentrating system placed in the light cylinder, the LED ligh...
