Background technology

The LED lamp is a semi-conductor lighting lamp, with light emitting diode as light source, because light emitting diode is based on the efficient solid state light emitter that the faint electric energy of the usefulness of semiconductor PN formation just can be luminous, so, have environment friendly and pollution-free, characteristics such as caloric value is extremely low, little power consumption, light efficiency height, life-span length, thereby LED just is being widely used in illumination as the light source of saving the energy.

Existing Medical Cold Light Source can be divided into two big classes by the difference of selecting luminescent device for use, and a class is to utilize electric current that the object of metal or pottery and so on is heated to incandescent degree and the light source (being the solid thermal radiating light source) that produces, as halogen tungsten lamp, fill xenon halogen tungsten lamp etc.; Another kind of then is under electric field action, and electric current is radiative light source (being glow discharge spot lamp) by ionized gas, as xenon lamp, various metal halide lamp.Two kinds of equal complex structures of light source, and not truly " cold light source ", two kinds of its luminaires of light source all produce a large amount of heats, light need be by non-spherical mirror face, this minute surface plating multilayer dielectric film absorbs infrared ray, reduces the thermal radiation temperature of fiber end face, but also needs auxiliary heat dissipation equipment such as fan, thereby when cold light source and endoscope were used simultaneously, the temperature that endoscope is held part and light emission parts reached instructions for use.The structural volume of this complexity is big, damage easily, radiating effect is poor, service life is shorter.

With present main flow endoscope 300W xenon lamp commonly used is example, reaches the led light source that identical illuminating effect then only needs 25W with it.And xenon lamp is at the trigger impulse voltages that start moment need several ten thousand volts, and after xenon lamp was lighted, the Switching Power Supply supply current was near 20A.Power supply is fragile, and Energy Efficiency Ratio is lower.So led light source is energy-saving with it, determined it to have bright development prospect.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of medical led light source, is possessing under the good illumination prerequisite, and its volume is minimum, and energy consumption is extremely low, stable performance, and the life-span is long, is convenient to promote the use of.

For achieving the above object, the utility model adopts following technical scheme:

The LED Medical Cold Light Source of a kind of pair of light source dual power supply, comprise cabinet, place two groups of led light sources of cabinet and pass electro-optical device, and power supply, described power supply and described led light source are integrated on the pcb board and realize electrically connecting, also comprise a heat radiation matrix, described heat radiation matrix is connected with described pcb board.

Preferably, described biography electro-optical device is that optical fiber passes light beam.

As improvement, also comprise at least one smooth output interface, an end of described smooth output interface is connected with the biography electro-optical device, and the other end passes the aperture that is provided with on the cabinet.

As further improvement, also comprise button, described button is arranged at the outer surface of cabinet, and realizes electrically connecting with pcb board.

The luminous efficiency of the LED lamp that preferably, described led light source adopted is greater than 110Lm/W.

Preferably, described heat radiation matrix comprises substrate that is connected with pcb board and a plurality of radiating fins that are connected with described substrate.

Preferably, be provided with a louvre along radiating fin orientation extension on the described substrate at least.

The power supply light source integrated LED lamp that the utility model is set forth, its beneficial effect is:

1. cold light source truly directly sends low temperature light from LED, need not extra cooling system such as coated reflective mirror and fan, simplified structure, reduced volume.

2. have outstanding luminous efficiency, good Energy Efficiency Ratio is saved the energy greatly.

3. the fuselage caloric value is little, noiselessness, no waste gas.

4. two light sources are for light, and double circuit is powered.

5. in light weight, simple in structure, volume is little, and cost is lower, has long service life, popularization easy to use.
