Description

CHANNEL SIGN WITH VARIOUS EXPRESSION OF SIDE LIGHTING}

The present invention relates to a channel sine emphasizing side lighting, and more particularly, to a channel sine capable of producing various side lightings that are used for advertisements and that are capable of measuring various effects and colors.

Recently, a lot of character signboards are being applied to government regulations on beautiful plate-type signs and beautiful city scenery. Also, the demand for lighting channel signs is increasing indoors due to the appearance of large shopping malls and movie theaters.

This advertising or lighting channel sign is generally attached to the top and the light consisting of the front light-transmitting synthetic resin plate, the lighting color sheet and the trim for supporting and combining the bottom and the three-dimensional shape of the bottom plate and the letter following the expressed form of the top. It is composed of three-dimensional plate to determine the lower part, and mainly use screws (pieces) to fix the upper and lower parts.

A light source, which is mainly used as a light emitting diode, is disposed inside the channel sign of this structure, and a switched-mode power supply (SMPS) for applying power to the light source is mounted outside.

Conventional channel sign is formed in the form of a letter, image or symbol, so the metal material is mainly used to reinforce the mechanical strength of the side portion, and the lighting effect is applied to the front plate and the rear portion through the light source. Has disadvantages that are difficult to expect.

In addition, the conventional photometric channel sign is mainly made of acrylic, resin plate material, etc., laser processing the letter form to combine with the metal frame portion, or the process of bending and bending by applying heat due to the restoring force when bending or bending the plate material Difficulty in the production of expensive materials and complicated processing such as post-processing due to deformation and shrinkage of the material when using a lot of processing process or plate in this process, such as manufacturing cost, production period, follow-up management, etc. .

In order to solve this problem, the applicant has applied for and registered the side lighting structure of the channel sign as disclosed in the registration number 10-1053719 (side lighting structure of the channel sign).

However, the side lighting structure of the channel sign disclosed in the registration No. 10-1053719 can be said to be very encouraging in comparison with the conventional side in terms of the side luminous effect, simplified by extrusion molding of the light diffusion resin material and at a low manufacturing cost Although it was possible to produce the product, the side plate was produced by extruded metal plate with a synthetic resin containing light diffusing material in the form of a plate, so that the finishing material was finished with the light diffusing resin material, thereby deteriorating the appearance quality.

In addition, in the case of a conventional character channel for advertising is to perform a frame molding for fixing the screen, at this time, the portion fixing the screen is mainly used a metal material and the metal frame portion has a problem that the illumination is obscured.
