Abstract

The utility model relates to the technical field of reflecting shades, and particularly relates to a reflecting shade of a lamp, which comprises a bowl-shaped main body; a through hole for placing a lamp tube is formed on the main body; the main body comprises an outer protective layer, a nano reflective layer and an inner protective layer; the bottom surface of the nano reflective layer is coated with the nano reflective layer; and the bottom surface of the nano reflective layer is coated with the inner protective layer. Since the nano reflective layer has good reflectivity on visible light, i.e. higher reflectivity, when rays emitted by the lamp are irradiated to the bottom surface of the main body, most rays are uniformly reflected and can be fully used for lighting, the brightness of the lamp is enhanced and the lighting effect of the lamp is improved; furthermore, the reflectivity of the nano reflective layer is decayed slowly. Compared with the traditional reflecting shade of an anodized aluminum plate, the utility model has longer service life.

Description

A kind of light fitting reflecting cover

Technical field:

The utility model relates to the reflection shield technical field, relates in particular to a kind of light fitting reflecting cover.

Background technology:

General light fixture all is mounted on the bearing, and the light that light fixture sends equably to around disperse, so really do not play the effect of illumination in fact near the light of bearing one side, for this reason, people install reflection shield usually between light fixture and bearing, its surface near light fixture one side has reflecting properties preferably, and the light near bearing one side can be mapped to earlier on the reflection shield like this, reflex to the front by reflection shield again, thereby increase the brightness of light fixture and improve the illuminating effect of light fixture.But common in the market reflection shield mostly is the aluminium sheet anodic oxidation reflection shield that is bowl-shape, in use, this reflection shield not only reflectivity to visible light is lower, and the oxidation jaundice that can raise because of the temperature of bulb, cause the decay of reflectivity to be accelerated, shorten the service life of reflection shield.

The utility model content:

The purpose of this utility model is exactly to provide a kind of reflectivity height, the slower light fitting reflecting cover of reflectivity decay at the deficiency of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is:

It comprises the main body that is bowl-shape, offers the through hole that is used to place fluorescent tube on the main body, and described main body is made up of external protection, nanometer reflector layer, inner protective layer, and the nanometer reflector layer is sprayed on the bottom surface of external protection, and inner protective layer is sprayed on the bottom surface of nanometer reflector layer.

Described nanometer reflector layer is the multi-element metal crystal layer less than 100 nanometers.

The thickness of described nanometer reflector layer is 0.3～0.5 micron.

Described external protection is polyester PU type paint (claiming a polyurethane paint again) layer, also can be glassy layer.

Described inner protective layer is a glassy layer, also can be silicon dioxide layer.

The bottom surface of described main body is provided with corrugated striped.

The opening part of described main body is provided with flange.

The opening of described main body is a rectangle.

The utility model beneficial effect is:

A kind of light fitting reflecting cover that the utility model provides comprises the main body that is bowl-shape, offer the through hole that is used to place fluorescent tube on the main body, described main body is made up of external protection, nanometer reflector layer, inner protective layer, the nanometer reflector layer is sprayed on the bottom surface of external protection, and inner protective layer is sprayed on the bottom surface of nanometer reflector layer; Because the nanometer reflector layer has good reflectivity to visible light, be that reflectivity is higher, so when the light of light fixture shone the bottom surface of main body, its most of light was reflected away equably, can fully be used for illumination, thereby increase the brightness of light fixture and improve the illuminating effect of light fixture; And the reflectivity decay of nanometer reflector layer is slower, compares with traditional aluminium sheet anodic oxidation reflection shield, the utlity model has longer service life.

Fig. 5 is external protection, the nanometer reflector layer of the utility model embodiment two, the structural representation of inner protective layer.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described, please refer to Fig. 1～4, be embodiment one of the present utility model, it comprises the main body 1 that is bowl-shape, offer the through hole 2 that is used to place fluorescent tube on the main body 1, described main body 1 is made up of external protection 11, nanometer reflector layer 12, inner protective layer 13, and nanometer reflector layer 12 is sprayed on the bottom surface of external protection 11, and inner protective layer 13 is sprayed on the bottom surface of nanometer reflector layer 12; Described nanometer reflector layer 12 is the multi-element metal crystal layer less than 100 nanometers, and it is mainly made by metals such as silver, copper, has the slow characteristics of reflectivity height, reflectivity decay, wherein, can reach 90% to the reflectivity of visible light.Therefore, when the light of light fixture shone the bottom surface of the utility model main body 1, its most of light can be reflected away equably, made the most light of light fixture can be used for illumination, thereby increased the brightness of light fixture and improve the illuminating effect of light fixture; Simultaneously,, compare, the utlity model has longer service life, so the utility model can be widely used on the light fixtures such as street lamp, shot-light with traditional aluminium sheet anodic oxidation reflection shield because the decay of the reflectivity of the utility model nanometer reflector layer 12 is slower.

The thickness of present embodiment nanometer reflector layer 12 is 0.3～0.5 micron, and the thickness of external protection 11 is 15～20 microns, and described external protection 11 is a polyester PU type skin of paint, is used to protect the end face of nanometer reflector layer 12; Described inner protective layer 13 is a glassy layer, is used to protect the bottom surface of nanometer reflector layer 12.

The bottom surface of present embodiment main body 1 is provided with corrugated striped 3, to increase the reflective surface area of main body 1 bottom surface, improves the reflectivity to visible light; The opening part of described main body 1 is provided with flange 4, is used for the whole reflection shield of clamping; The opening of described main body 1 is a rectangle, and promptly the shadow surface of light fixture is a rectangle, makes that the range of exposures of light fixture is wide and even.

Please refer to Fig. 5, be embodiment two of the present utility model, what present embodiment and embodiment one were different is that described external protection 11 is glassy layer, is used to protect the end face of nanometer reflector layer 12; Described inner protective layer 13 is a silicon dioxide layer, is used to protect the bottom surface of nanometer reflector layer 12; Other structure is identical with embodiment one in the present embodiment, does not repeat them here.

Certainly, the embodiment of the above, it is better embodiment of the present utility model, be not to be used for limiting practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, and are included in the utility model patent claim.
