Description

Direct current cartridge type scope lighting device

Technical field

The utility model relates to a kind of scope lighting device, and is particularly a kind of as building element, has the direct current cartridge type scope lighting device of acoustical absorption heat preserving effect.

Background technology

At present, conditional electronic, fiberendoscope in order to observe and obtain the sign information that required information comprises human body a part, need sufficient light source in use.And the light source of at present traditional electronics, fiberendoscope use is the external cold light source, and this cold light source great majority are to adopt the sensitive lamp of halogen as light source.Be connected by optical cable between the output port of cold light source and the scope inner fiber porch, just the illumination light that the sensitive lamp of halogen is sent imports to the top of straight tube endoscope by optical fiber cable.This external cold light source still has sufficient illumination for guaranteeing the light that imports to endoscope distal end, need the power supply of several hectowatts, so power consumption is big, and service life is restricted, approximately have only about 500～1000 hours, and this external cold light source volume is big.

This traditional electronics, fiberendoscope are in use, also must filter to focus on to light source and handle by a series of components and parts, a large amount of infrared light compositions are filtered to guarantee being cold light source, therefore cost is higher, simultaneously owing to cold light source and scope need be used in combination, cold light source and scope inner fiber interface drag one with the optical cable of long heaviness, cause very inconvenient in the use, so traditional electronics, fiberendoscope are not easy to field operation, are not easy to carry.

Therefore, need especially a kind of simple in structure, volume is little, be easy to carry, low-cost direct current cartridge type scope lighting device.

The utility model content

The purpose of this utility model is to provide a kind of direct current cartridge type scope lighting device, and is simple in structure, volume is little, be easy to carry, low price, remedies traditional electronics, the deficiency of fiberendoscope.

The technical problem that the utility model solved can realize by the following technical solutions:

A kind of direct current cartridge type scope lighting device, it is characterized in that, it comprises a housing, in described housing, be provided with the high-power LED lighting module, described LED lighting module is connected with the LED light emitting diode, described LED lighting module is connected with battery by the battery tray of led module bottom, and described case top is connected with the optical fiber introducing port of scope.

Be provided with the condenser that is used for the light that the LED light emitting diode produces is carried out optically focused, increase light-source brightness above described LED light emitting diode, described condenser is fixed on described LED light emitting diode top by the optically focused microscope base.

In order to prevent that the LED light emitting diode from producing the operate as normal of the too high described LED lighting module of temperature effect when working, be provided with the heat sink of being convenient to dispel the heat between described LED light emitting diode and LED lighting module.

Be provided with the insulation board of the electric pole short circuit that prevents module on described LED lighting module, the generating electrodes short circuit influences the work of whole device when preventing that the LED lighting module is connected with battery.

Top at described housing is provided with connector, by described connector described housing is connected with the optical fiber introducing port of described scope, is convenient to install or unloading.

Direct current cartridge type scope lighting device of the present utility model compared with the prior art, by the LED lighting module is set in housing, connect the LED light emitting diode by the LED lighting module and produce light source, increase the brightness of light source by the condenser on the LED light emitting diode, the connector that is arranged on the housing top is convenient to described direct current cartridge type scope lighting device is installed on the scope or from scope described direct current cartridge type scope lighting device is unloaded, be easy to carry, realize the purpose of this utility model.
