Abstract

The invention relates to a light cone system, particularly to a light cone system for cold light source focusing, and is applied to a medical endoscope lighting source. The light cone system comprises a glass light cone and a gas discharge lamp, wherein the roughness of the outer surface of the glass light cone is 0.006 micrometer, the glass light cone is sleeved with a heat-dissipation seat, the outer surface of the glass light cone is coated with a total-reflection film layer contacted with the heat-dissipation seat, according to the glass light cone, L2=D1=3-100 mm, and L1=L2+(D1+D2)/2=4.5-150 mm; the gas discharge lamp is sleeved with a reflection bowl, the reflection bowl and the D1 end of the glass light cone are distributed in a spaced and matched manner, and the gas discharge lamp is connected with an electric lamp connecting wire. The light cone system for cold light source focusing is high in structural compactness, low in cost, reliable in performance, high in focusing efficiency and low in output temperature.

Description

A kind of light cone system for cold light source focusing
Technical field
The present invention relates to a kind of light cone system, more particularly, to a kind of light cone system for cold light source focusing, for medical Endoscope illumination light source.
Background technology
In cold light source high-power light-emitting source all using gas-discharge lamp or LED lamp, by parabolic reflective focusing or pass through Optical lens group focuses on, and this two kinds of mode light efficiencies are low to burn optical fiber in focus point generation high temperature simultaneously.Current solution is only The import heat fusing optical fiber of price superelevation.On market, the light cone of the existing no focusing that this patent is mentioned is used for medical light source.
Content of the invention
The present invention mainly solves the deficiencies in the prior art, provides a kind of compact conformation, can will be large-area Hot spot is focused into the area of design requirement, and the brightness improving light reduces the temperature of output optical surface simultaneously, and the output light conical surface can Direct and light guide bundles optical fiber directly contact carries out passing light, a kind of high light cone system for cold light source focusing of optical transmission efficiency.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of light cone system for cold light source focusing, including the gentle body discharging lamp of glass light cone, described glass light cone The roughness of outer surface is 0.006 micron, and described glass light dimension is outer to be cased with radiating seat, and the outer surface of described glass light dimension covers There is the total reflection film layer touching with radiating seat phase, in described glass light cone: l2=d1=3-100mm, l1=l2+ (d1+d2) ÷ 2=4.5-150mm;It is cased with reflector, the d1 end in described reflector and glass light cone is separately outside described gas-discharge lamp Coupling distribution, described gas-discharge lamp is connected with electric light line.
Preferably, described radiating seat be externally provided with equally distributed heat sink strip.
Solve the problems, such as that higher source luminance focuses on and burn optical fiber.
Pass through total reflection film on Vacuum Deposition in glass light cone outer surface, gas-discharge lamp is connected with power supply by line and carries out Power supply, carries out focusing on for the first time by reflector, the light focusing on for the first time enters from the d1 end of glass light cone, and near infrared light passes through Reflectance coating is radiated by radiating seat again.Luminous ray, after taper surface inner total reflection, is focused into the light beam of a diameter of d2, reaches To focusing effect.
Glass light cone possesses heat-insulated effect, and the thickness of glass determines effect of heat insulation, but thickness is blocked up can affect light Transmitance, the such size of l2=d1, l1=l2+ (d1+d2) ÷ 2 can reach optimal effect.
A kind of light cone system for cold light source focusing that the present invention provides, compact conformation degree is high, and with low cost, performance can Lean on, focusing efficiency is high, output temperature is low.
Brief description
Fig. 1 is the structural representation of the present invention;
Fig. 2 is glass light cone cross section structure diagram in the present invention.
Specific embodiment
Below by embodiment, Structure Figure, technical scheme is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, a kind of light cone system for cold light source focusing, gentle including glass light cone 1 Body discharging lamp 2, the roughness of described glass light cone 1 outer surface is 0.006 micron, is cased with radiating outside described glass light dimension 1 Seat 3, the outer surface of described glass light dimension 1 is covered with the total reflection film layer 4 mutually touching with radiating seat 3, described glass light cone 1 In: l2=d1=3-100mm, l1=l2+ (d1+d2) ÷ 2=4.5-150mm;It is cased with reflector 5 outside described gas-discharge lamp 2, Described reflector 5 separately mates distribution, described gas-discharge lamp 2 and electric light line 6 phase with the d1 end in glass light cone 1 Connect.
Described radiating seat 3 be externally provided with equally distributed heat sink strip 7.
