Abstract
This utility model belongs to medical diagnosis and treatment lighting source, relates to a kind of free from glare LED medical diagnosis and treatment lamp cylinder with microstructural diffusion plate lampshade.It is characterized in that the polymer light diffuser plate to have micro structure as lampshade, its structure, by base, shell, circuit printing plate, reflector, lampshade retainer ring, has a surface micro-structure light diffusing sheet lampshade, LED, controls switch and power pack composition.Described have surface micro-structure light diffusing sheet lampshade and be placed in lampshade retainer ring, is installed on reflector front end, and covers LED.Lampshade retainer ring is connected with outer casing screw with fixing light diffusing sheet lampshade.This utility model utilizes the light diffusing sheet with surface micro-structure to the disperse function of light and to turn light characteristic, under not reducing brightness of illumination premise, solve the glare problem during LED light source uses, closely by sense of discomfort produced by LED strong illumination during elimination patient assessment, reduce the potential injury to patient's eye.
Description
Technical field:
This utility model relates to a kind of free from glare LED medical diagnosis and treatment lamp cylinder with microstructural diffusion plate lampshade, belongs to doctor
By diagnostic illumination source, it is possible to use as a kind of handheld portable daily life lighting source.
Background technology:
Department of eye (having another name called: eye, ear, nose, specialty of pharyngolaryngology) disease is common disease, can severely impact the normal raw of people
Live, human body is had the biggest injury.Medical diagnosis and treatment torch, lamp pen, mouth lamp etc. be ENT doctor be patient check eye, ear,
Nose, the conventional illuminations of throat disorders.
Owing to the light fixture with LED as light source has of fine quality, durable, energy-conservation distinguishing feature, current LED flashlight, lamp pen are five
Official section is more and more applied in checking.LED light source is typically all the point source of Single wavelength, and when encapsulation the most all
Having convex lens, lens to have the effect concentrated by light, therefore, the light that LED light source sends is eager to excel a lot than ordinary incandescent lamp.By
In the luminous concentration of LED, directivity is relatively strong, easily produces higher brightness in institute's irradiation area and produces glare problem, makes
People produces sense of discomfort under LED strong illumination, even causes visual function to reduce.
Having the LDE lighting for medical use product that the LED integrated technology using anti-halation white ground glass produces at present, such produces
Product can improve the injury to human eye of the LED high light to a certain extent, but owing to the use of white ground glass can not
Make light fixture light transmittance with exempting from reduces, and have impact on the irradiation brightness of LED lamp, shows its function limitation in actual use
Property.
Summary of the invention:
For solving medical diagnosis LED flashlight, lamp the intense light source potential hazard to patient's vision, when eliminating patient assessment
Originally, on the premise of not reducing light source brightness of illumination, this utility model carries sense of discomfort produced by closely under strong illumination
For a kind of, there is with surface the micro-structural polymer light diffusing sheet free from glare LED medical diagnosis and treatment lamp cylinder as lampshade, solve doctor at present
By diagnosis and treatment LED flashlight, lamp pen glare problem in use.
This utility model solves its technical problem and be the technical scheme is that to have the polymer light of surface micro-structure
Diffuser plate is applied in medical department of eye illumination light tube structure, it is provided that a kind of surface has the nothing that micro structure light diffusing sheet is lampshade
Dazzle LED medical diagnosis and treatment lamp cylinder.Utilize optical lens principle, by having that the preparation of polymeric material minute manufacturing technology produces
The polymer light diffuser plate of surface micro-structure can be as a kind of luminous intensity distribution material, it is achieved high-light-energy balances with high evenness.Lamp cylinder
Primary structure, by base, shell, circuit printing plate, reflector, lampshade retainer ring, has surface micro-structure polymer light diffuser plate
Lampshade, LED, control switch and power pack composition.Described have surface micro-structure polymer light diffuser plate lampshade, is high score
Sub-polymeric material, the micro structure that its surface has can have various ways: its shape can be the hemispherical of depression, V-type
Groove, U-type groove etc.；Its arrangement can be rectangular array, hexagon arrangement, multinomial arrangement etc..Described have surface micro-structure light
Diffuser plate lampshade is placed in lampshade retainer ring, is installed on reflector front end, and covers LED.Lampshade retainer ring and shell spiral shell
Stricture of vagina connects with fixing light diffusing sheet lampshade.LED is fixed on circuit printing plate and by this circuit printing plate and power pack
Connecting, overall package is in the enclosure.Shell is connected with whorl of base.The break-make of power supply is by described control on-off control.
The beneficial effects of the utility model are the lampshades as LED of the polymer light diffuser plate to have surface micro-structure.
Utilize the polymer light diffuser plate disperse function effective to light with surface micro-structure, make LED point light source pass through light diffusion
Effectively dissipate after plate so that irradiation light becomes uniform, and its irradiation brightness is unaffected.Application of the present utility model is permissible
Eliminate when patient seeks medical advice closely by sense of discomfort produced by LED strong illumination, solve the glare problem during LED light source uses,
Reduce the LED light source potential injury to patient's eye.Simultaneously as the micro structure that light diffusing sheet has turns light characteristic so that light
The light transmittance of diffuser plate is up to 70-90% so that it is brightness of illumination is unaffected.
Accompanying drawing illustrates:
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing is the structure chart of the free from glare LED medical diagnosis and treatment lamp barrel structure with microstructural diffusion plate lampshade.
In the drawings, 1, base, 2, shell, 3, circuit printing plate, 4, reflector, 5, lampshade retainer ring, 6, there is surface micro-
Structural polymer light diffusing sheet lampshade, 7, LED, 8, control switch, 9, power pack.
Detailed description of the invention:
There is the free from glare LED medical diagnosis and treatment lamp barrel structure of microstructural diffusion plate lampshade by base 1, shell 2, circuit printing
Plate 3, reflector 4, lampshade retainer ring 5, there is surface micro-structure polymer light diffuser plate lampshade 6, LED 7, control switch 8, electricity
Source part 9 forms.
Described have surface micro-structure polymer light diffuser plate lampshade 6, is macromolecule polymer material, and its surface has
