Abstract
The utility model discloses a reflective lampshade, which comprises a lamp shell. The lamp shell is formed by combining a neck-shaped head part, a first reflective part, a second reflective part and a transparent bottom part. The inner surface of the neck-shaped head part from the middle part to the first reflective part and the second reflective part is coated with a metal coat. From top to bottom, the first reflective part is a paraboloid spreading outwards along the inside of the lamp shell and the axes of the first reflective part is superposed with the axes of the lamp shell. From top to bottom, the second reflective part is the paraboloid which is drawn close along the outside of the lamp shell. The utility model has the first reflective part and the second reflective part. The first reflective part can reflect light transmitted by a light source directly. The second reflective part reflects the light transmitted by the light source onto the first reflective part which reflects the light then. Light beams transmitted from the transparent bottom part is superposed, therefore the illumination intensity is greatly improved.
Description
Technical field
The utility model relates to a kind of reflection lampshade that is used for various light fixtures.
Background technology
The patent No. is that the utility model patent of CN96249513.1 discloses a kind of " electricity-saving lamp reflection lampshade ", is constituted with the reflectorized material of lower part but had the high temperature resistant lampshade of connecting ring and spread upon lampshade inside 2/3rds by the bottom.Because of but lampshade inside is coated with reflectorized material, the light part that light source sends directly penetrates, and another part penetrates via the reflectorized material reflection again, though obtained the light beam of broad, improves the light efficiency of lamp, does not improve intensity of illumination.
Summary of the invention
The utility model has overcome above-mentioned the deficiencies in the prior art, provides a kind of and not only can improve light efficiency, can also significantly improve intensity of illumination, and keeps the reflection lampshade of good beam uniformity.
The technical solution of the utility model is achieved in that
A kind of reflection lampshade, comprise lamp housing, described lamp housing is to be merged mutually by neck shape head, first reflecting part, second reflecting part and printing opacity bottom, middle part to the first reflecting part of neck shape head and the inner surface of second reflecting part scribble the layer of metal coating, first reflecting part is to the parabola of outside diffusion along lamp housing inside from top to bottom, and the axis of first reflecting part and the dead in line of lamp housing, second reflecting part is a parabola of drawing close to inside along the lamp housing outside from top to bottom.
As preferably, described second reflecting part is an arc surface.
In order to play uniform reflecting effect, as preferably, the circle centre position of described arc surface is on the axis of lamp housing.
As preferably, described metal coating is an aluminized coating.
Adopted the beneficial effects of the utility model of technique scheme to be:
The utlity model has first reflecting part and two reflectings surface of second reflecting part, first reflecting part can be directly reflects away the light of light emitted, second reflecting part reflexes to the light of light emitted on first reflecting part and reflects away via first reflecting part, the light beam that the printing opacity bottom is penetrated is through stack, thereby intensity of illumination improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: a kind of reflection lampshade, comprise lamp housing 1, described lamp housing 1 is to be merged mutually by neck shape head 2, first reflecting part 3, second reflecting part 4 and printing opacity bottom 5, middle part to the first reflecting part 3 of neck shape head 2 and the inner surface of second reflecting part 4 scribble layer of metal coating 6, and described metal coating 6 is an aluminized coating.
First reflecting part 3 is the parabolas that spread to the outside along lamp housing 1 inside from top to bottom, and the axis of first reflecting part 3 overlaps with the axis 7 of lamp housing 1; From top to bottom second reflecting part 4 be one along lamp housing 1 outside to inside draw close parabola, second reflecting part 4 is an arc surface, and the circle centre position of arc surface is on the axis 7 of lamp housing 1.
