Abstract

The utility model discloses a reflective lampshade. The reflective lampshade comprises a glass casing, wherein the glass casing is formed by joining a neck-shaped head part, a first reflective part, a second reflective part and a transmitting bottom; a metal coating is applied from the middle part of the neck-shaped head part to the inner surface of the first reflective part and the inner surface of the second reflective part; from the top to the bottom, the first reflective part is a paraboloid which diffuses outwards from the inside of the glass casing, and the second reflective part is a paraboloid which closes inwards from the outside of the glass casing; the height of the first reflective part is between 8.5 and 11cm, and the thickness of a ring of the first reflective part formed by vertical projection on a plane is between 3 and 5cm; the height of the second reflective part is between 0.5 and 1.2cm, and the thickness of a ring of the second reflective part formed by vertical projection on a plane is between 0.2 and 0.8 cm. According to the reflective lampshade, the shapes, the heights, the widths of the first reflective part and the second reflective part are reasonably arranged, so that light can be better reflected, and high lighting effect can be achieved.

Description

Reflection lampshade

Technical field

The utility model relates to a kind of lampshade, particularly a kind of reflection lampshade that can be applicable to various light fixtures.

Background technology

Existing reflection lampshade is on the glass bulb inwall, to scribble metallic reflector, and various light sources are set in lampshade then, and the light of light source penetrates through lampshade; Obtained the light beam of broad, improved its light efficiency and brightness to a certain extent, but found in using; It still has deficiency; Such as when being applied to the higher place of required intensity of illumination, still not competent, tracing it to its cause, it is reasonable inadequately mainly to be that the shape of glass bulb is provided with.

Summary of the invention

The utility model has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of and not only can improve light efficiency, can also significantly improve intensity of illumination, and keeps the good inhomogeneity reflection lampshade of beam spread.

The technical scheme of the utility model is achieved in that

A kind of reflection lampshade; Comprise glass bulb; Described glass bulb is to be merged mutually by neck shape head, first reflecting part, second reflecting part and printing opacity bottom, and middle part to the first reflecting part of neck shape head and the inner surface of second reflecting part scribble metal coating, and first reflecting part is to the parabola of outside diffusion along glass bulb inside from top to bottom; And the axis of first reflecting part and the dead in line of glass bulb; Second reflecting part is the parabola drawn close to inside along the glass bulb outside from top to bottom, and the height of described first reflecting part is 8.5～11cm, and the thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3～5cm; The height of second reflecting part is 0.5～1.2cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.2～0.8cm.

As preferably; The height of first reflecting part is 9cm; The thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3cm, and the height of second reflecting part is 0.6cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.3cm.

As preferably, described metal coating is an aluminized coating.

Adopted the beneficial effect of the utility model of technique scheme to be:

The reflection lampshade of the utility model has first reflecting part and two reflectings surface of second reflecting part; The light that first reflecting part can directly be launched Halogen lamp LED reflects away; The light that second reflecting part is launched Halogen lamp LED reflexes 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; The most important thing is that the utility model has carried out reasonable setting to height, the width of first reflecting part, second reflecting part, makes light better to reflect, thereby has obtained high light efficiency.

The specific embodiment

The specific embodiment of the utility model is following:

Embodiment: a kind of reflection lampshade; As shown in Figure 1; Comprise glass bulb 1; Described glass bulb 1 is to be merged mutually by neck shape head 2, first reflecting part 3, second reflecting part 4 and printing opacity bottom 5, and 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 glass bulb 1 inside from top to bottom, and the axis of first reflecting part 3 overlaps with the axis 7 of glass bulb 1; From top to bottom second reflecting part 4 be one along glass bulb 1 outside to inside draw close parabola; The height of first reflecting part is 9cm; The thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3cm; The height of second reflecting part is 0.6cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.3cm.
