[1] The present invention relates to a light controller, commonly known as a light cover.

Background technique

[2] The light controller is widely used in the field of illumination, which controls the illumination by concentrating the light from the source to a specified direction.

[3] The light controller used daily is usually shaped into a light-collecting surface, which has the disadvantages of high production cost, heavy weight and inconvenient storage and transportation.

[4] The scattering type light controller can enlarge the light-emitting area of the light source, can create a softer lighting effect and produce a more obvious display effect; the scattering type light controller is often applied to the light quality. In lighting systems, such as photography, videography, etc.

[5] The current scattering type of light controller is usually manufactured by adding a scattering medium to the output light path of the light controller, and there are also disadvantages such as high production cost and troublesome installation.

Provides the purpose of the lighting effect of the inflatable light controller.

[16] In the inflatable light controller provided by the present invention, the transparent light transmitting region is disposed near the scattering light transmitting region, and the transparent light transmitting region is offset from a central region of the scattering light transmitting region. The light source itself, which is mounted in the transparent light-transmissive region, is prevented from causing significant obstruction to light emitted through the scattered light-transmitting region.

[17] In the inflatable light controller provided by the present invention, one of the two sheets of airtight material is a light transmissive plastic film, and the other of the two airtight materials is an aluminized plastic film. And a transparent plastic film matched with the light source is spliced on the aluminum-plated plastic film; or one of the two air-tight materials is a transparent light-transmissive plastic film, and the other two pieces of the air-tight material are It is a partially aluminized transparent plastic film, and the portion of the transparent plastic film that is not plated with aluminum is matched with the light source.
