Abstract
The utility model relates to the technical field of lighting products, in particular to a reflective lampshade. The body of the reflectively lampshade is provided with a reflector for gathering and reflecting light; and the reflecting surface of the reflector is a step surface. Due to the adoption of the technical scheme, the reflective lampshade has the following advantages that: firstly, due to the adoption of the step reflecting surface, beams radiated from a light source are reflected within a certain range rather than focusing on a focus after being reflected by the step surface, so the beams are uniformly radiated on the ground and the utilization rate of the light source is greatly improved.
Description
Technical field:
The utility model relates to the illuminating product technical field, refers in particular to a kind of lampshade.
Background technology:
Reflection shield refers to light fixture in use, can not impinge upon a kind of reflector that the light on work and the life face reflects to what light source sent.Can improve the utilization rate of lamp luminescence greatly by reflection shield, Luminaire efficiency is improved greatly.
For example, generally speaking, home-use illuminating lamp places the top in room, and its light is to be space whole step angular dispersed around the middle mind-set with lamp body.At that time, because the people's activities zone is below lamp body, so the light that lamp body produces has only 120 ° to be utilized by people, the wide part of other directions had all been wasted.In order to improve the utilization rate of light fixture light, all can add a reflection shield or reflector generally speaking to lamp.At present, one of the light utilization efficiency of judgement reflection shield main research parameter is exactly the moulding of reflection shield.Modal reflection shield is the round speaker mouth with parabolic surface, and products such as searchlight, flashlight all adopt this design.What the reflection shield of fluorescent lamp adopted is the horn mouth of a rectangle or class rectangle, and its reflecting surface also adopts curved surface usually.Such diffuser mainly is that light is reflexed on the focus, forms concentrated luminous.
If using, above-mentioned reflection shield in the street lamp facility, just has deficiency.This is because according to the road Lighting Design standard, the illumination on the road surface has uniformity requirement over far away ten meters of the distance lamp stands on road surface under the light fixture.If still adopt this illumination mode with light-ray condensing, will make that the light under the light fixture is too bright, can produce dazzle, its main lighted region concentrates in less " focus " scope, and on distance lamp stand road surface far away the brightness obvious zone of " focus " secretly just in the center.Caused the inhomogeneous of reflection ray distribution like this, the effective area of street lamp irradiation is too small, so that there is the blind area between the street lamp.
The utility model content:
Technical problem to be solved in the utility model just is to overcome the existing deficiency of present street lamp reflecting shade, and a kind of lampshade that can be used in the street lamp product is provided.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: the main body of this lampshade is provided with the reflection shield that is used for light is assembled reflection, and the reflective surface of described reflection shield is a cascaded surface.
Described main body is provided with most reflection shields.
Described reflection shield is bell mouth shape, and the bottom surface offers the through hole that is used to be provided with illuminator.
The reflective surface of described reflection shield is multistage cascaded surface.
Described main body is by punching press or integrated through injection molding moulding reflection shield.
After the utility model has adopted technique scheme, it has following advantage: at first, it adopts the staged light-emitting area, the light of radiation of light source can be in not accumulating in one " focus " after reflecting through cascaded surface, but can be reflected in certain scope, so just make the uniform irradiation of light on ground, the light source utilization rate improves greatly.Secondly, the present invention adopts the mode of integrated punching moulding to form a plurality of reflection shields on main body, this lampshade can be applied in the LED product, each diffuser bottom is provided with one group of light emitting source, whole light fixture is made of some diffusers, and irradiation just strengthens greatly to the light intensity apart from lamp stand road surface far away like this.
Description of drawings:
Fig. 1 is a stereogram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing this full mold is further described:
See Fig. 1, lampshade described in the utility model comprises: main body 1, this main body 1 are provided with the reflection shield 2 that is used for light is assembled reflection.Main body 1 adopts metallic plate punching to form or uses the heatproof injection-moulding plastic, the evenly distributed some reflection shields 2 that are formed with on main body 1.
The be square horn mouth moulding of (or class is square) of reflection shield 2 main bodys of the present utility model, its four reflective surfaces are cascaded surface.Offer the through hole 21 that is used to be provided with illuminator at a less end (being the bottom surface).The light source that illuminator produces will reflex to the below by vertical plane on the cascaded surface.The light of illuminator radiation of light source is not through can be in accumulating in one " focus " after the cascaded surface reflection like this, but can be reflected in certain scope, so just makes the uniform irradiation of light on ground, and the light source utilization rate improves greatly.
