High-brightness LED (Light Emitting Diode) cold light source device

Abstract

The invention relates to a high-brightness LED (Light Emitting Diode) cold light source device, which is mainly suitable for laparoscopic surgery or hysteroscopy of a human body. The device is characterized in that: an LED lamp comprises an LED substrate, an LED luminous body, a luminous body protection plate, a power supply guide plate, an LED power supply joint and an insulator, wherein the LED luminous body, the luminous body protection plate, the power supply guide plate, the LED power supply joint and the insulator are positioned on the same side of the LED substrate, and are encapsulated with the LED substrate together to form an integrally-formed LED lamp; the luminous body protection plate including the LED luminous body is directly adjacent to a heat insulator; a light hole main body, the heat insulator, the luminous body protection plate and the LED luminous body are arrayed in sequence; the luminous body protection plate is close to the LED luminous body; and the LED luminous body corresponds to a light hole channel. The device has a reasonable, simple and compact structural design, is convenient, reliable and safe to use and install and has low manufacturing cost, high illumination, good radiating and surgery effects, a long service life, small heat productivity and a better comprehensive effect.

Description

technical field [0001] The invention relates to an LED cold light source device, in particular to a high-brightness LED cold light source device, which is mainly suitable for endoscopic operations such as human laparoscopy or hysteroscopy. Background technique [0002] In the prior art, the illuminance of medical LED cold light sources is relatively low, generally no more than 1500LM, and cannot be used in laparoscopic surgery or hysteroscopic surgery, and can only be applied to ENT surgery; at the same time, the existing medical LED cold light source Dimming uses a shading plate mechanism to control the illuminance of the light. The structure of the mechanism is complex, and the motor is easily damaged. [0003] Chinese Patent No. 2009200906542 discloses a utility model patent named "Medical Endoscope LED Cold Light Source". The LED cold light source is connected with the lens assembly, the lens assembly is connected with the light cone sleeve, and the end of the light con...

AI Technical Summary

Problems solved by technology

Although the cold light source device with this structure has good heat dissipation and satisfactory illuminance, it is equipped with a light shield, a reflector cup, and a condenser cup. The motor of the plate mechanism to control the light intensity is easily damaged

[0005] In addition, there are other inventions and utility model patent applications for LED cold light sources, but their structural design is even more unreasonable; at the same time, the structure of LED cold light sources disclosed in the prior art cannot be simply combined, even with common knowledge. Combination, otherwise the effect of surgery will be even worse: or lead to insufficient illumination, or lead to complex structure, or lead to poor heat dissipation, or lead to low service life, or lead to impractical implementation, or lead to a combination of the above shortcomings
