Problems solved by technology

The above-mentioned light bulbs have some disadvantages: high power, high heat, short life
At present, the cold light sources on the market have not solved the contradiction between the output light intensity and various safety hazards (fire, injury to patients, glare, etc.) caused by the heat absorption of the object.
Although there are light intensity adjustment functions, in most

Example Embodiment

[0015] from figure 1 It can be seen from the figure that a medical energy-saving and safe cold light source consists of a chassis 1, a power supply circuit board 2, a light bulb 3, a light guide connector 4, a control circuit 5, a cooling fan 6, a motor 7, a shading sheet 8, and a video input terminal 9 and so on. The chassis 1 is the carrier of all components. The 220V AC power supply is connected to the power supply circuit board 2, and the 220V AC mains power is converted into the voltage and current that the light bulb 3 can normally use through the power supply circuit board 2, and then flows through the control circuit 5 It is controlled, and then connected to the light bulb 3 to light up; the light guide connector 4 is installed in the case 1, and is used to connect with other medical equipment through an optical fiber. The cooling fan 6 is also installed on the casing 1 for cooling the light bulb and the like. The above composition and structure belong to the prior ...

Abstract

The invention relates to an adaptive cold light source, which consists of a case, a power circuit board, a bulb, a light guide bundle connector, a control circuit, a cooling fan, a motor, a shading plate and a video input terminal. A video signal is connected into the control circuit; the video signal is subjected to amplification of a video amplifying circuit and analog-to-digital conversion, and then is analyzed and processed by a CPU to have a maximum value; and by using the value, a motor dimming circuit controls the motor to drive the shading plate to rotate at different angles so as to control the output light intensity through non-shading, partial shading and full shading for the output light, and the output light intensity is adaptively adjusted so as to fulfill the aim of an light-source adaptive camera for luminance requirement and provide luminance required for the camera and a photographed object.

Description

technical field [0001] The invention relates to a related technical field of medical equipment, in particular to a medical self-adaptive cold light source that can be used during use. Background technique [0002] As we all know, at present, most of the cold light sources used in endoscopes in domestic and foreign medical devices use bulb-type lights, which are cooled and focused and then transmitted to the inside of the endoscope through optical fibers. The types of bulbs are mainly divided into the following four types: Halogen Bulb type, xenon lamp type, metal halide lamp type, and short arc lamp, the short arc lamp has the smallest power, and the power of the first three is 100W~350W. The above-mentioned light bulbs have some disadvantages: high power, high heat generation, and short service life. in addition. The existing medical cold light source will focus in a range after the bulb is turned on, and the brightness is very high. It is connected to the optical fiber t...
