Abstract

The utility model relates to a reflector lampshade of lighting lamp and belongs to mechanical category. The reflector lampshade is a flat and semi-ellipse hallow mask body, the upper and lower part of the inside of the mask body are provided with symmetric micro-arch reflection surface, a micro-arch side reflection surface is formed between the upper and lower micro-arch reflection surfaces, the micro-arch side reflection surface is composed of a plurality of small side reflection surfaces in vertical apposition and a pipe shroud stretches in the center of the micro-arch side reflection surface, which can be used for the assembly of the lamps so as to reach the effect of the best condense of light and the strong brightness. The utility model has the advantages of simple structure, function of concentrating light, increasing the brightness of the light projection and high practicality.

Description

The reflection shield of illuminating lamp

Technical field

The utility model relates to electrical category, particularly a kind of reflection shield of illuminating lamp.

Background technology

As everyone knows, illuminating lamp inside is provided with reflection shield, this reflection shield has common point and comprises the horn-like or semi-spherical shape that is flaring from inside to outside, and wall outwards is radial tangent plane or the cambered surface that becomes to have most different angles that separate from the center within it, to reach the effect of tool multi-angle reflect; Yet, reflection shield commonly used at present, though cut apart the reflective tangent plane that majority is arranged in horn-like or the design of semi-spherical shape inwall, can be made for that the crossover of multiple angle is reciprocal penetrates effect, but still there is following shortcoming: after bulb inside produces light, can outwards be 180 degree three dimensions projections, in this kind can't active set, under the situation of light source, just can cause light to disperse to form a kind of low light level phenomenon from the reflection shield openend, and shorten the distance that light can shine, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of reflection shield of illuminating lamp, solved that existing reflection shield exists can't active set in light source and easily cause light to disperse to form a kind of low light level phenomenon, and shorten the problems such as distance that light can shine.

The technical solution of the utility model is: be provided with and be flat semiellipse hollow cover body without exception, its inner upper and lower end mask has symmetrical bandy differential of the arc reflective surface, Jie becomes the differential of the arc side reflective surface of a parabolic between upper and lower differential of the arc reflective surface, this differential of the arc side reflective surface generally is made of the vertical little side reflective surface arranged side by side of majority, and a pipe box has extended back in differential of the arc side reflective surface center, can be for the bulb assembling, to reach the effect that the light that bulb produces can be made best optically focused and highlighted.

Advantage of the present utility model is: simple in structure, have the light harvesting function, and can effectively increase the illuminance of light projection, practical.

The specific embodiment:

As accompanying drawing 1 to shown in the accompanying drawing 4, the utility model reflection shield 10 generally is a flat semiellipse hollow cover body, its openend design is a flat ellipticity, advance so that on its inside, the lower surface has the little differential of the arc reflective surface 11 to relative outside curve of symmetry, and between last, be formed with the differential of the arc side reflective surface 12 that a parabolic is indent between the following differential of the arc reflective surface 11, this differential of the arc side reflective surface 12 is generally linked with mode one vertically arranged side by side by the rectangular little side reflective surface 121 of majority, moreover, the position in the center of differential of the arc side reflective surface 12 to the anti-pipe box 122 with pore that is extended with, can be for bulb 70 from this place's assembling, after being located at reflection shield 10 positioned internal when the bulb group, can do the upper-lower interactive refraction by the light that differential of the arc reflective surface 11 about the symmetry produces bulb, to have the function of the light intensity that increases reflection shield 10 inside; In addition, utilize the most little side reflective surface 121 of this differential of the arc side reflective surface 12 light can be concentrated and do same direction refractive power projection, to reach the cohesion light source and to increase the effect of brightness to openend.

Shown in accompanying drawing 5 and accompanying drawing 6, for the utility model is applied in the embodiment of bicycle lamp, this bicycle lamp comprises:

One base housing 20, being provided with a dividing plate 21 makes it separate preceding storage tank 22 of formation and rear end battery accommodating groove 23, wherein, storage tank 22 both sides are provided with the semicircle orifice 221 of symmetry before being positioned at, and have all protruded out one in two semicircle orifices, 221 front and back ends and collude post 222, and the position is formed with symmetrical chute at battery accommodating groove 23 outer bottoms, and be inserted in end at chute and be provided with bumping post, in view of the above, the quick detach snap-fastener 30 that this chute can provide the slide fastener winding can be locked on vehicle frame, bumping post then can be for quick detach snap-fastener slide fastener end against the location; Again, the position is provided with circuit control panel 24 and power switch key 25 in the top of dividing plate 21 group;

One upper shell 40, the upper end that can close cover be buckled in the preceding storage tank 22 of base housing 20, the semicircle orifice 41 that its both sides are provided with symmetry can be combined to form symmetrical button hole 42 with the semicircle orifice 221 of base housing 20 both sides, the position forms symmetry in the front and back end of both sides semicircle orifice 41 and colludes groove 411, can with base housing 20 both sides respectively to collude post 222 involutory; Upper shell 40 tops are arranged with soft release knob 43 can be involutory in above-mentioned power switch key 25;

One battery slip lid 50, but battery accommodating groove 23 tops that provide slide fastener to be positioned at base housing 20;

One transparent housing 60 can be linked in the openend that base housing 20 and upper shell 40 formed it is sealed, and these transparent housing 60 both sides are extended with the chimeric block 61 that outside side protrudes, and can be fastened on above-mentioned symmetrical button hole 42;

The utility model reflection shield 10, inner assembling are provided with an electricity bubble 70, and it can be contained in transparent housing 60 inside, and openend can paste the Inner Front End face that is against transparent housing 60;

Form by above-mentioned member, this reflection shield 10 can provide increases the effect that bicycle lamp produces best focus irradiation.
