Abstract

The utility model relates to an inflatable light controller which comprises an inflatable cavity which is formed by the combination of two soft airtight materials with same size along the edges. After the inflatable cavity is inflated, the two airtight materials plump up to form two opposite curved surfaces; and the two airtight materials are provided with a light reflecting zone (1) and a scattering photic zone (2) as well as a transparent photic zone (21). After light emitted by a light source (3) enters the interior of the inflatable cavity through the transparent photic zone (21), light entering the light reflecting zone (1) is reflected, and the light is emitted from the scattering photic zone (2) finally, thus playing the role of controlling the light. The transparent photic zone (21) is provided with a plurality of scales (211), and the control effect of the inflatable light controller can be adjusted by installing the light source (3) by referring to the scales (211).

Description

A kind of inflatable light controller

Technical field

The utility model relates to a kind of light controller, is commonly called as lampshade.

Background technology

The light controller is widely used in lighting field, and it makes light cover that light source the sends direction to appointment, thereby has controlled the effect of illumination.

Light controller used in everyday normally is shaped into hard material the light harvesting curved surface and forms, and has the deficiency of production cost height, heavier and inconvenient accumulating.

The light controller of diffuse transmission type then can make the light-emitting area of light source enlarge, and can build softer illuminating effect and produce significantly display effect; In the illuminator that diffuse transmission type light controller often is applied to light quality is had higher requirements, for example photograph, occasion such as shooting.

The light controller of present diffuse transmission type adopts the mode of additional scattering medium on the output light path of light controller to make usually, also has deficiencies such as production cost is higher, installation trouble.

The utility model content

The utility model provides a kind of inflatable light controller, on production cost, weight and accumulating volume remarkable advantages is arranged.

The inflatable light controller that the utility model provides comprises one by the gas-filled cavity of two airtight materials along the edge be combined into, described two airtight materials are soft, be filled with air in described gas-filled cavity, described two airtight materials are heaved and are formed two curved surfaces in opposite directions; Be provided with at least one reflective areas and at least one transparent area on described two airtight materials, in described gas-filled cavity inside, the light that is mapped to described reflective areas will be reflected, and light finally can only be penetrated by described transparent area, plays the effect of control light.

The processing technology that described two airtight materials are combined into gas-filled cavity is ripe, for example the production method of plastic sheeting balloon.Described gas-filled cavity processing technology when continuous-flow type is produced, require usually described two airtight materials be can be paved and also be identical in the shape when being paved.

The folding of straight line can be arranged on described airtight material, and the characteristic that the described airtight material maintenance after folding can be paved can satisfy the requirement of described gas-filled cavity processing technology; Constant for the extension direction at the edge that guarantees described airtight material, described folding folding line normally even number appears on wherein a slice among described two airtight materials (comprising that zero degree is folding, promptly folding).After the inflation of described gas-filled cavity, the shape that the curved surface that folding described airtight material forms arranged can be variant with the shape of the curved surface that not folding described airtight material forms.

Be appreciated that described airtight material can be spliced by some raw material as long as keep described airtight material to be paved.

In the inflatable light controller that the utility model provides, described transparent area can be the diffuse transmission type printing opacity, can appear softer light, perhaps can satisfy the needs that enlarge display area; Described scattering transparent area can by integral body use the diffuse transmission type printing opacity material, splicing diffuse transmission type printing opacity material or on material transparent mode such as additional scattering layer form.

In the inflatable light controller that the utility model provides, be provided with additional reflector layer on the surface of described reflective areas outside described gas-filled cavity.Common aluminized plastic film is high reflective, but still has by fraction light and can see through, and described additional reflector layer can reduce this light losing, improves the reflecting rate of described reflective areas.

In the inflatable light controller that the utility model provides, be provided with additional diffusion layer on the surface of described reflective areas in described gas-filled cavity.It is that diffuse transmission type is reflective that described additional diffusion layer makes the surface of described reflective areas in described gas-filled cavity, also is the softer a kind of mode of light that inflatable light controller that the utility model is provided sends.Certainly, also can reach same purpose by the reflective raw-material mode of direct production diffuse transmission type.

In the inflatable light controller that the utility model provides, described airtight material is provided with transparent transparent area, described transparent transparent area and light source are complementary, and the light that described light source is sent can be injected the inflatable light controller inside that the utility model provides smoothly; The parts that described light source is installed can be set near described transparent transparent area; Indication can be set near described transparent transparent area the sign of the position of described light source is installed, described Warning Mark can be a plurality of, can offer selection, by selecting the position of the different described light sources of installation, can regulate the light that sends by described light source inject under the angle of gas-filled cavity, reach the purpose of the illuminating effect of regulating the inflatable light controller that the utility model provides.

In the inflatable light controller that the utility model provides, described transparent transparent area is set near the described scattering transparent area, and described transparent transparent area departs from the middle section of described scattering transparent area, with the described light source itself of avoiding being installed in described transparent transparent area the light that sends by described scattering transparent area caused significantly and blocks.

In the inflatable light controller that the utility model provides, wherein a slice of described two airtight materials is the plastic sheeting of scattering printing opacity, other a slice of described two airtight materials is an aluminized plastic film, and splicing has the transparent plastic film that mates with light source on aluminized plastic film; Perhaps, wherein a slice of described two airtight materials is the plastic sheeting of scattering printing opacity, and other a slice of described two airtight materials is the transparent plastic film of local aluminizing, and the part of not aluminized on the described transparent plastic film is complementary with light source.

Inflatable light controller volume when not inflating that the utility model provides is very little and can be folded, and carrying cost is very low.

The inflatable light controller that the utility model provides be inflated described gas-filled cavity at a need and promptly finish installation, and is easy to use; In conjunction with the inflation/accessory that loses heart, the inflatable light controller that the utility model provides can use repeatedly.
