for achieving the above object, the technical solution used in the present invention is: a kind of LED medical endoscope cold light source with the synthesizing jet-flow heat radiation, comprise housing, it is characterized in that: described housing one end is equipped with heat sink, a described heat sink side is equipped with LED light source, described LED light source arranged outside has reflection shield, described LED light source is connected with power-supply controller of electric on being arranged on housing, the described housing other end is equipped with and passes the light beam socket, described biography light beam socket inboard is provided with reflective light cone, on described biography light beam socket, the biography light beam is installed, described heat sink non-LED light source one side is equipped with the base with a plurality of cavitys, described cavity is communicated with extraneous air by aperture, described cavity inside is positioned at and vibrating mass is installed on heat sink, described vibrating mass is connected with power-supply controller of electric.
Described LED light source is arranged on reflection shield focus place.
Described biography light beam socket center via diameter is complementary with the biography beam diameter.
The present invention compared with prior art has the following advantages:
(1) this LED medical endoscope cold light source design with the synthesizing jet-flow heat radiation is very reasonable, simple in structure, operator only need can automatically complete active heat removal to vibrating mass this device of switching on, and operator need not training and get final product complete operation, use very easy.
(2) the anti-dust contamination resistance of LED medical endoscope cold light source with the synthesizing jet-flow heat radiation is very strong, and reliability is very high.
(3) the LED medical endoscope cold light source volume with the synthesizing jet-flow heat radiation is little, lightweight, is convenient to very much carrying, transportation and installs.
(4) the LED medical endoscope cold light source durability with the synthesizing jet-flow heat radiation is high, dispels the heat by combining jet device, and heat dissipation capacity improves greatly, and without any noise.
(5) all be convenient to very much produce, buy with a lot of parts of LED medical endoscope cold light source of synthesizing jet-flow heat radiation, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.
