Linear illuminants with special-shaped cross-section

Abstract

PROBLEM TO BE SOLVED: To provide an irregular shaped cross section linear light emitter that allows quick attaching operation to a fixture object, further prevents removal from an attachment surface and interlayer peeling between a core layer and a cladding layer in attachment, and that can emit well-balanced light across a portion away from an end where a light source is arranged.SOLUTION: A light emitter body R of a linear light emitter attached and fixed to a recess or a salient of a fixture object F comprises: a core layer 1 made of a transparent resin having a refractive index larger than that of the air; and a cladding layer 2 made of a translucent resin having a refractive index smaller than that of the core layer 1 and larger than that of the air, and formed so as to cover any portion for emitting light on the surface of the core layer 1. An attachment portion A capable of being attached to the recess or the salient of the fixture object F is formed by moulding the core layer 1 into an irregular shaped cross section including a stripe-like projection part 12 or a groove part.

Description

technical field [0001] The present invention relates to the improvement of a linear illuminant, in particular, to a linear illuminant with a special-shaped cross-section, which can not only be easily installed with respect to the fixed object, but also The peeling of the core layer and the cladding layer is also less likely to occur during mounting, and light can be emitted in a well-balanced manner from the end where the light source is placed to a remote location. Background technique [0002] As we all know, most of the colorful lights and lighting signs use linear illuminants like neon lights. The neon lights made of glass tubes cannot bend the linear illuminants along the wall because the illuminants themselves are not flexible. The bending part attaches or bends the linear luminous body to draw pictures and characters. [0003] Therefore, an optical fiber-type linear light-emitting body has been developed in the past. The fiber-optic linear light-emitting body has fle...

Problems solved by technology

[0006] However, in the linear luminous body of the above-mentioned prior art, since the protrusions and grooves are only formed by shaping the outer covering layer into a deformed cross section, the thickness of the outer covering layer becomes locally large, and there is a part where the light becomes easy to pass through. Leaked Cons

Therefore, a large part of the light leaks from the mounting surface side (the side opposite to the visible surface) of the linear light emitter, and it is impossible to make the linear light emitter emit light in a well-balanced manner from the light source to a distant position.

[0007] Moreover, the above-mentioned prior art linear luminous body, because it is installed on the object to be fixed in a bent state, only the outside of the object to be fixed is inserted or locked in the concave portion of the object to be fixed. The cladding (protrusion) has a structure that applies a load in the bending direction, so delamination easily occurs between the cladding that receives a direct load from the object to be fixed and the core that indirectly receives a load from the cladding
