Description

The hand-held cold light source of LED

Technical field

The present invention relates to be applied to the cold light source of medical field illumination, particularly the hand-held cold light source of a kind of LED.

Background technology

The existing cold light source that is applied to area of medical diagnostics endoscope illumination, mainly usings Halogen lamp LED or xenon lamp as illuminator, and light utilization efficiency is low and heat is high, energy waste is serious.

Be illustrated in figure 1 existing cold light source structure, cold light source 01 is powered by AC220V, and cold light source 01 is derived light beam by optical fiber 02, conduct to endoscope 03, the shortcoming of this structure is, makes that cold light source volume is large, complex structure and need optical fiber to derive, and uses loaded down with trivial details.

Summary of the invention

The defect existing in order to overcome above-mentioned prior art, the invention provides the hand-held cold light source of a kind of LED, and long service life, works more reliable, and light efficiency is high and temperature is low; Volume is little, compact conformation, hand-held, uses more conveniently, adopts DC work, power supply mode flexibility and reliability.

To achieve these goals, technical scheme of the present invention is as follows:

The hand-held cold light source of LED, comprises handle, is arranged on LED light source and controller in handle, and galvanic cradle and power supply adaptor are provided, and described controller is by chip in connection LED light source;

Described LED light source is positioned at handle top, directly dock with endoscope on the top of described handle, the bottom of handle is arranged in described cradle, and the surface of described handle arranges a plurality of function buttons, and described function button is connected with the controller of handle inside by circuit respectively.

Further, the function button that the surface of described handle arranges comprises power switch button, time/brightness display button, set of time button and brightness regulation button, these function buttons are in a row vertical shape, are positioned at staff gripping place of handle middle part, facilitate people's manual operating.Described each function button is connected with the controller of handle inside by circuit respectively, and function button is transferred to described controller by signal, by controller, LED light source is carried out to correlation function.

The object of described set of time button is the LED lamp pearl in protection LED light source, and work calories sheds in time, forces interruption work, thereby has guaranteed the service life of LED lamp pearl.

The object of described brightness regulation button is to guarantee that viewable portion is clear, and LED light is regulated, and makes it without highlight.

Further, the surface of described cradle arranges interface and is connected with power supply adaptor, and its inner hollow facilitates the bottom of above-mentioned handle to insert in cradle, and being convenient to provides a safe and reliable strong point for whole hand-held cold light source structure, can in time electric energy be supplemented again, guarantee normal work.

Described cradle converts access 220V alternating current to direct current by power supply adaptor cradle is charged, and cradle can store a certain amount of direct current, when equipment also can continuous operation certain hour without electricity or have a power failure in the situation that and light unattenuated.

Described LED light source is comprised of LED lamp pearl and LED chip, and described LED lamp pearl is installed on handle and endoscope joint, is convenient to the light that LED light source sends and is directly used in endoscope illumination, and light loss minimizes, and uses also very convenient.

It is light emitting source that the present invention adopts LED, and light converges into spot light and at utmost received by mirror end face, and main body is handle type, and all functions key is all arranged on handle, and the object that the time is set is protection LED lamp pearl.

The invention has the beneficial effects as follows, compare the advantage having be with traditional cold light source: the brightness of (1) 5WLED light source and the Halogen lamp LED of 250W or the xenon source of 150W is suitable, this device is high and temperature is low to the utilization rate of light, more can be referred to as cold light source; Its colour temperature is that 6000K more approaches daylight than existing halogen light source 3600K colour temperature.

(2) the hand-held cold light source of LED has structurally saved fiber section, directly docks with endoscope, and efficiency improves greatly, and makes volume little many, more compact structure.

(3) before, cold light source can only be AC power supply, cannot work, and the hand-held cold light source of LED is DC work during power failure, both can AC power supply also can DC power supply, even also can continuous operation 4 hours without electricity or have a power failure in the situation that and light unattenuated.

(4) the hand-held cold light source processing of LED is simple, saves raw material, and cost reduces greatly, uses simply, and the life-span is long.

Accompanying drawing explanation

Fig. 1 is the structural representation of traditional cold light source.

Fig. 2 is structural representation of the present invention.

The specific embodiment:

In order to make creation characteristic of the present invention, technological means and to reach object, be easy to understand understanding, below in conjunction with specific embodiment, further set forth the present invention.

Embodiment:

Referring to Fig. 1, the hand-held cold light source of a kind of LED, comprise agent structure handle 1, be arranged on the LED light source 2 in handle 1, be arranged on the power switch button 6 on handle 1 surface, time/brightness display button 7, set of time button 8 and brightness regulation button 9, also comprise cradle 4 and power supply adaptor 5, endoscope 3 is directly docked on the top of handle 1, LED light source 2 is comprised of LED lamp pearl and LED chip, described LED lamp pearl is installed on the joint of handle 1 and endoscope 3, saved the optical fiber coupling part in former cold light source structure, make its volume little, more compact structure, and be convenient to the light that LED light source 2 sends and be directly used in endoscope illumination, light loss minimizes, use also very convenient.
