One end of a medical switch power source is connected with the power socket, the other end of the medical switch power source is connected with a light-emitting diode (LED) actuator, the other end of the LED actuator is connected with an LED light source, the LED light source is fixed on a substrate, the other end of the substrate is fixed with a radiator, a focusing assembly which is arranged inside a focusing assembly outer shell is arranged in front of the LED light source, an optical fiber is fixed on the focusing assembly outer shell, light emitted by the LED light source passes the focusing assembly and then is converged and collimated, an optical fiber port is formed in a converging port, and the LED light source emits white cold light which can be adjusted in light intensity under the effect of an LED drive device. The medical light source is small in size, good in heat dissipation, adjustable in light intensity, simple and convenient to operate and the like.
Description
Technical field
The present invention relates to a kind of light source, be specifically related to a kind of medical light source.
Background technology
Along with the development of medical optical instrument and universal, the particularly extensive use of the medical endoscope such as arthroscope, laparoscope in clinical Minimally Invasive Surgery, more and more higher to quantity and the characteristic requirements of Medical Cold Light Source.The basic function of Medical Cold Light Source is to produce cold light, can for the various endoscopes that adopt optical fibre light guide as light source, provide the brightness illumination for carrying out the inner chamber O﹠E.Medical light source not only will have enough luminous fluxes, high color temperature, and wants reliable operation, uses safety.Halogen tungsten lamp light efficiency and the colour temperature of early application are lower, and color reductibility is poor, although can reach high color temperature at present, owing to self being gas-discharge lamp, the life-span is short.
Along with the development of LED technology, the LED lamp is applied in road lighting and room lighting field widely, on medical, further development has been arranged also, but luminous efficiency and package dimension and brightness adjustable aspect on still must improve.
Summary of the invention
In order to overcome the problems referred to above, the invention provides a kind of medical light source, can reduce effectively that heat, brightness that light emitting source produces are adjustable, application is strong.
The present invention adopts following technical scheme:
A kind of medical light source, comprise supply socket 1, medical Switching Power Supply 3 one ends are connected connection with supply socket, the other end is connected connection with LED driver, the other end of LED driver 4 is connected connection with LED light source, LED light source 7 is fixed on substrate 6, substrate 6 other end fixed heat sink 5, be arranged on the place ahead that focus pack shell 9 interior focus packs are located at LED light source 7, optical fiber 14 is fixed on focus pack shell 9.
Described optical focus assembly comprises heat shield 8, the first optical lens 10, the second optical lens 11, focussed collimated lens 12 successively from the place ahead of LED light source 7, and described the first optical lens 10, the second optical lens 11 and focussed collimated lens 12 are coaxial.
The optical axis of described focus pack and LED light source 7 center superpositions.
Described substrate 6 planes are perpendicular to the axis of optical focus assembly.
The port of described optical fiber 14 is fixed on focussed collimated lens 12 outsides by trip bolt.
Described supply socket is used for connecting the 220V civil power, supplies with to medical Switching Power Supply.
Described medical Switching Power Supply 3 converts civil power to+5V and-two kinds of DC voltages of 12V, give LED driver 4 power supplies.
Described LED driver 4 adopts has the high-brightness LED driver that impulse width modulation and light adjusting is controlled function, thereby can effectively change the brightness that dutycycle is regulated LED, realizes 100～0% dimming scopes, can avoid noise simultaneously.
Described LED light source adopts white LED light source, is evenly distributed on substrate 6 for the integrated form chip or with many.
Adopt LED light source, utilize medical Switching Power Supply that civil power is converted to the medical applications DC voltage, to the LED driver power supply, regulate supply current by LED driver, thereby change the brightness of LED lamp, realize the LED light modulation.Through concentrating component, the light that LED light source sends is conducted to optical fiber after polymerised, for endoscope provides illumination.
