The focusing collimating lens is fixed in front of the casing, the thermal insulation sheet, the first optical lens and the second optical lens are fixed in the casing respectively through a pair of corresponding clamp grooves on the side of the casing, the first optical lens, the second optical lens and the focusing collimating lens form a coaxial line of an optical assembly, the plane of the substrate is perpendicular to the axis of the optical assembly, the center of the LED light source is arranged on the axis of the optical assembly, light emitted by the LED light source is thermally insulated by the thermal insulation sheet, light with large divergence angles is shaped into good-quality light beam by the first optical lens, the light is focused by the second optical lens, and finally the light is changed into collimating light beam by the focusing collimating lens. The optical system is high in light emitting efficiency and good in imaging quality.
Description
Technical field
The present invention relates to a kind of optical system, be specifically related to a kind of optical system of medical examining lamp.
Background technology
Along with the development of medical optical instrument and universal, the particularly extensive use of the medical endoscope such as arthroscope, peritoneoscope 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 endoscopies 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 roadway illumination and room lighting field widely, on medical, further development has been arranged also, but optical system must improve still on aspect luminous efficiency and image quality.
Summary of the invention
In order to overcome the problems referred to above, the invention provides a kind of optical system of medical examining lamp, have that luminous efficiency is high, the characteristics of good imaging quality.
The present invention adopts following technical scheme:
a kind of optical system of medical examining lamp, it is characterized in that: comprise housing 8, be fixed on the substrate 1 of housing 8 back, be fixed on the LED light source 2 on substrate 1, be arranged on the heat shield 3 in LED light source 2 the place aheads, be arranged on first optical lens 5 in heat shield 3 the place aheads, be arranged on second optical lens 6 in first optical lens 5 the place aheads, be arranged on the focussed collimated lens 7 in second optical lens 6 the place aheads, focussed collimated lens 7 are fixed on the place ahead of housing 8, described heat shield 3, the first optical lens 5 and the second optical lens 6 are fixed in housing 8 by a pair of draw-in groove 4 corresponding to housing 8 sides respectively, described the first optical lens 5, the optical module coaxial line that the second optical lens 6 and focussed collimated lens 7 consist of, described substrate 1 plane is perpendicular to the axis of optical module, the center of described LED light source 2 is on the axis of optical module.
Described LED light source adopts white light LEDs.
Described white light LEDs is integrated form or adopts many to be evenly distributed on substrate 1.
Adopt technique scheme, adopt white LED light source to be fixed on substrate, the light that LED light source sends is heat insulation through heat shield, be shaped to quality light beam preferably by the first optical lens light that the angle of divergence is large, through the second light lens focus, form the collimated beam outgoing by the focussed collimated lens at last again.Have that luminous efficiency is high, the characteristics of good imaging quality.
