Abstract

(57) [Summary] (Modifications) [Problem] The present invention is an LED illuminator whose main feature is that light is emitted over a wide area and uniformly through a diffused resin in a shape of a bump. [MEANS FOR SOLVING PROBLEMS] ・ LED inside a diffusion resin in the shape of a kamaboko
Are arranged to emit light, whereby irregular reflection in the diffusion resin and light along the shape of the diffusion resin are uniformly emitted to a large area to the outside. -Since the light is emitted in a wide range, the light irradiated to the irradiation target can be irradiated at an arbitrary angle according to the height of the LED illuminator. -By using a plurality of the above-mentioned bar-shaped LED illuminators, or by using a plurality of LED illuminators in combination, it is possible to irradiate an irradiation target of various shapes.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an LED illuminator used for image processing.

[0002]

[Prior art]

 Conventional LED illuminators can only irradiate in the direction in which the irradiation angle is determined due to the mounting of the LED lamp.

[0003]

[Problems to be solved by the invention]

 Except for the drawbacks, the present invention aims to develop a single LED illuminator that can change its illumination angle.

[0004]

[Means for Solving the Problems]

 (B) LED lamps are built into the Kamaboko-shaped diffusion resin structure. (B) Light is emitted over a wide area through the diffusion resin.

[0005]

[Embodiment of the invention]

 Since the present invention has the above structure, when using this structure, by changing the height from the irradiation target, an arbitrary irradiation angle can be obtained, so that an image necessary for image processing can be selected.

[Utility model registration claims]

Claims (2)

[Utility model registration claims] 1. A light emission from an LED can be changed to a scattered light which emits light over a wide area by using a diffused resin structure having a convex shape. This is an LED illuminator in which the angle of the irradiating direction changes according to the height relationship of the LED illuminator from the irradiation target, and irradiation at an arbitrary angle is possible. 2. The use of a plurality of bar-shaped LED illuminators or a combination of a plurality of bar-shaped LED illuminators according to claim 1 makes it possible to irradiate an irradiation target of various shapes arbitrarily. .
