Abstract
The utility model relates to an illuminating device for an endoscope, and which consists of a casing, an electric power device, an illuminating original assembly and a connection of the light output. The electric power device consists of a supply socket, a power switch and an rectifying electric power board. The rectifying electric power board is separately connected with the illuminating original assembly and a lighting adjustment assembly arranged in the casing through the conductors, a focusing optical system is arranged between the illuminating original assembly and the connection of the light output. The light emitted by the illuminating original assembly is adjusted to the needed lightness through the lighting adjustment assembly, and is focused and output through the focusing optical system to be used as the light sources. The utility model has the advantages of small volume, low power consumption, convenience for carrying, long service life, low cost, and the lightness of the light output can be adjusted at random within a certain range.
Description
Technical field
This utility model relates to a kind of illuminator, relates in particular to a kind of cold light source lighting device that is used for endoscope.
Background technology
At present, the cold light source luminous body that the endoscope that uses on the medical diagnosis uses is single bulb, as Halogen light, xenon lamp etc.These luminous body power consumptions are big, give out a large amount of heats, and service life is restricted, and the light source volume is big.When using, also must filter to focus on to light source and handle, a large amount of infrared ray compositions are filtered to guarantee being cold light source, so cost be not low by a series of components and parts as the medical endoscope light source.The cold light source lighting device of medical endoscope use at present can not be regulated the brightness of light in addition, can not satisfy different instructions for uses, uses inconvenience.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of distribute heat is few, low, the long service life of power consumption, can adjust brightness output, the little lightweight cold light source lighting device of relative volume.
This utility model solves the above-mentioned technical scheme that technical problem adopted: this cold light source lighting device, comprise supply unit, cabinet, luminous original paper group is set in the described cabinet, the light output interface is arranged on the cabinet, its construction features is that described luminous original paper group is made of at least one LED.
Be provided with dimming components in the cabinet described in the utility model.
Be provided with light-gathering optics between luminous original paper group described in the utility model and the described smooth output interface.
This utility model compared with prior art has following beneficial effect: volume is little, low in energy consumption, use easy to carry, long service life, cost is low, and can regulate the brightness of output light within the specific limits arbitrarily, satisfies the different needs that use.

The specific embodiment
Referring to Fig. 1, Fig. 2, this utility model mainly is made up of cabinet 1, supply unit 2, luminous original paper group 6 and light output interface 8.Described supply unit 2 comprises supply socket 2-1, on and off switch 2-2, rectifier power source panel 2-3, all is fixed on the cabinet 1.Described rectifier power source panel 2-3 becomes unidirectional current with AC rectification, is connected with on and off switch 2-2, luminous original paper group 6 respectively by lead.Described luminous original paper group 6 is arranged at cabinet inside, is formed by several LED connection in series-parallel.
In order to satisfy different instructions for uses, dimming components 5 also is set, be connected with rectifier power source panel 2-3 by lead.Described dimming components 5 can regulate brightness arbitrarily by changing electric parameter to change brightness output within the specific limits.
In order to improve the brightness of output light, between described luminous original paper group 6 and described smooth output interface 8, light-gathering optics 7 is set.Described light-gathering optics 7 can be a meniscus group.And luminous original paper group 6, light-gathering optics 7, light output interface 8 vertical arranged in co-axial alignment make light beam directly inject light-gathering optics 7, reduce the loss of light.
During use, supply socket 2-1 is connected on the external power supply by power line, turns on the power switch 2-2, the light after adjusting is exported through light output interface 8 by light-gathering optics 7.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of this utility model.
Claims (3)
