Abstract
The utility model relates to a beam element used for endoscopes, in particular to a light cone comprising two ends (1-1), (1-2), which have different sizes and diameters of D and d. The utility model is characterized in that: a reflector (2) is arranged on the surface of the cone (1) and the refractive index of the cone material is higher than the refractive index of the reflector. The cone can be an integral optical material or formed by a plurality of stretching fibers (1-3). The section diameter ranges are: d=Phi 1 to 8mm, D=Phi 4 to 10mm, L=6 to 20mm. The utility model has the advantages of simple and reasonable structure, no loss of luminous energy through the light cone, thereby improves the illumination of the endoscope using light cone greatly.
Description
Technical field
The utility model relates to a kind of optical element, specifically is a kind of element of optically focused of endoscope use.
Background technology
Endoscope needs illumination when work.By light guide bundles light is guided to the mirror inner fiber from light source,, light is guided in the chamber of endoscope work by the mirror inner fiber.Obtain luminous energy for as much as possible from light source, the light guide bundles number of fibers is generally more, so sectional area is big.And the mirror inner fiber is subjected to the constraint of the mirror pipe diameter of endoscope, and negligible amounts is so sectional area is little.In order to solve this contradiction, need a kind of element of changing logical light area.Domestic endoscope product adopts the direct coupled mode of mirror inner fiber and light guide bundles more at present, middle this class component of nothing.
Chinese patent literature CN1349110A discloses a kind of " optical fiber cone drawing technology for making and equipment ", and light cone wherein is that the taper biography that a kind of two end faces vary in size resembles device, and certain transformation is arranged.But because this light cone uses single optical material, thereby luminous energy has certain loss in conversion.
Summary of the invention
The utility model technical issues that need to address are, overcome disadvantages of background technology, provide a kind of easy to use, the light cone of no optical energy loss.
Light cone of the present utility model, its cone have two end faces that differ in size, and it is characterized in that there is the reflection horizon on the cone surface, and the refractive index of cone material realizes total reflection greater than reflector material.Make as glass by optical material in cone and reflection horizon.The work in reflection horizon in order to guarantee light all by and all reflection pass through cone, from total reflection principle as can be known, the loss of the luminous energy by light cone is zero.Cone can be the monoblock optical material, also can be made of by stretching some optical fiber.
For the ease of processing, the bus of light cone can be one section, two sections or multistage, and the shape of every section line can be straight line (parallel with center line), oblique line or camber line.
The utlity model has simple and reasonable for structurely, the loss of the luminous energy by light cone is zero, makes the illuminance of the endoscope that adopts light cone be improved significantly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the use synoptic diagram of the utility model in endoscope.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1.See Fig. 1, this routine light cone cone has two end face 1-2,1-1 up and down, and the scope of its diameter of section and height is generally at d=Φ 1～8mm, and D=Φ 4～10mm selects between L=6～20mm; This example is respectively d=Φ 2.3mm, D=Φ 4.4mm, high L=14mm.The reflection horizon 2 on cone 1 and surface is glass material, and its refractive index is: n1=1.6128, n2=1.510.Because n1＞n2 constitutes the total reflection structure.This routine cone generatrices is divided two sections.Hypomere is the straight line that is parallel to center line, and epimere is an oblique line.
See Fig. 2, light cone is installed in the connection place of light guide bundles 6 and mirror inner fiber 4.The heavy in section 1-1 of light cone is identical with the cross section of light guide bundles 6, and the small bore 1-2 of light cone is identical with the cross section of mirror inner fiber 4.Make the transmittance process of luminous energy be in perfect condition, avoid because the waste that does not match and cause of sectional area.Moreover according to the structure of light cone, the utility model is in the quantity of the mirror inner fiber 4 that does not increase endoscope 3.Do not increase under the situation of power of light source 7, the illuminance of endoscope 3 is improved significantly.
Embodiment 2.See Fig. 3, this routine light cone cone is made of some optical fiber 1-3.All the other are with example 1.
Claims (5)
1, a kind of light cone, cone have two differ in size, end face (1-1), (1-2) that diameter of section is D, d, it has reflection horizon (2) for it is characterized in that cone (1) surface, the refractive index of cone material is greater than the refractive index of reflector material.
2, light cone according to claim 1 is characterized in that described cone (1) is made of some optical fiber (1-3).
3, light cone according to claim 1 and 2 is characterized in that described diameter of section scope is: d=Φ 1～8mm, D=Φ 4～10mm, L=6～20mm.
4, light cone according to claim 1 and 2 is characterized in that the light cone bus divides two sections.
5, light cone according to claim 3 is characterized in that the light cone bus divides two sections.
