Abstract

The invention discloses a reflective lampshade, which comprises a glass shell, a neck-shaped head, a first reflective part, a second reflective part and a transparent bottom are pieced together to form the glass shell, metal coating is applied from the middle of the neck-shaped head to the inner surfaces of the first reflective part and the second reflective part, the first reflective part is a paraboloid spreading from the inside to the outside along the glass shell from the top down, the second reflective part is a paraboloid closed up from the outside to the inside along the glass shell, the height of the first reflective part is 8.5cm to 11cm, the thickness of the ring formed by the vertical projection of the first reflective part on the horizontal plane is 3cm to 5cm, the height of the second reflective part is 0.5cm to 1.2cm, and the thickness of the ring formed by the vertical projection of the second reflective part on the horizontal plane is 0.2cm to 0.8cm. The invention reasonably arranges the shapes, heights and widths of the first reflective part and the second reflective part, so that light can be better reflected, and thereby high luminous efficiency is obtained.

Description

A kind of reflection lampshade

Technical field

The present invention 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 present invention 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.

Technical scheme of the present invention 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 invention has the beneficial effects as follows of technique scheme:

Reflection lampshade of the present invention 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 present invention 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.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

The specific embodiment of the present invention 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.
