JPH0628926U - UV blocking cover for fluorescent lamps - Google Patents

Abstract

(57) [Abstract] [Purpose] To provide an ultraviolet blocking cover that can be easily attached to and detached from a fluorescent lamp to protect displayed products from ultraviolet rays. [Structure] An ultraviolet cut layer is provided on the surface of a transparent resin cover body 1 having a U-shaped cross section. Open annular fitting pieces 2 having spring elasticity are attached to both inner ends of the cover body 1. The fitting piece 2 is detachably fitted to the fluorescent lamp 3 due to its spring elasticity, and the cover body 1 covers the fluorescent lamp 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to an ultraviolet ray blocking cover for fluorescent lamps used for lighting display products.

[0002]

[Prior art]

 When a product is displayed in a display case, a display shelf, or the like, since the product is illuminated by a fluorescent lamp, there is a problem that the product is discolored or deteriorated by the ultraviolet rays emitted from the fluorescent lamp, which lowers the commercial value. In order to prevent this, conventionally, a fluorescent lamp has been coated with a coating material containing an ultraviolet cut agent or covered with a tube containing an ultraviolet cut agent.

[0003]

[Problems to be solved by the device]

 However, in the conventional device, it is necessary to handle the fluorescent lamp so as not to damage the fluorescent lamp which is vulnerable to an external force or an impact, in order to give the fluorescent lamp an ultraviolet ray blocking function, which is troublesome. Further, even when the fluorescent lamp is replaced, it is necessary to add an ultraviolet blocking function to the new fluorescent lamp in advance, which is a troublesome problem.

An object of the present invention is to provide an ultraviolet ray blocking cover for a fluorescent lamp, which solves the conventional problems.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a cover body of a fluorescent lamp with an ultraviolet ray blocking function and allows the cover body to be easily attached to and detached from the fluorescent lamp. That is, in the ultraviolet protection cover for a fluorescent lamp of the present invention, an open annular fitting piece having spring elasticity is attached to the inside of a transparent resin cover body having a groove-shaped cross section, and the fitting piece is detachably fitted to the fluorescent lamp. Thus, the cover body covers the fluorescent lamp, and the cover body is provided with an ultraviolet blocking layer on the surface or contains an ultraviolet blocking agent inside.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. In the drawings, A is a cover of the present invention, which is composed of a cover body 1 and a fitting piece 2, and 3 is a fluorescent lamp.

The cover body 1 is made of a transparent resin such as polycarbonate or acrylic resin. The cover body 1 is a long body having a groove-shaped cross section sufficient to cover the fluorescent lamp 3, and generally has a U-shaped cross section as shown in FIG. Further, the cover body 1 is provided with an ultraviolet blocking function.

This ultraviolet blocking function is generally provided by coating the surface of the cover body 1 with a solution containing an ultraviolet blocking agent or by adhering a film containing an ultraviolet blocking agent and providing an ultraviolet blocking layer. ing. Further, the cover body 1 may be provided with an ultraviolet blocking function by being molded from a material containing an ultraviolet blocking agent.

Examples of the above-mentioned UV cut agent include those containing an organic UV absorber such as a benzotriazole-based, benzophenone-based, salicylic acid-based, or an inorganic UV-absorber of a metal oxide such as zinc oxide or titanium oxide. Any known material such as a mixture of the above may be used.

The fitting piece 2 is made of a material having spring elasticity such as metal or synthetic resin, and has an open ring shape that can be fitted into the fluorescent lamp 3. As shown in FIG. 1, the fitting piece 2 is generally attached to both inner ends of the cover body 1 by suitable means such as riveting so that its opening faces the same direction as the opening of the groove of the cover body 1. Installed. Further, the opposite opening edges of the fitting piece 2 are curved outward so that the fitting piece 2 can be easily fitted into the fluorescent lamp 3.

In the cover A of the invention, the cover body 1 covers the fluorescent lamp 3 by fitting the fitting piece 2 to the fluorescent lamp 3 as shown in FIG. 2 due to its spring elasticity. In addition, when removing, the cover body 1 may be pulled to remove the fitting piece 2 from the fluorescent lamp 3. The cover A may be attached and detached while the fluorescent lamp 3 is attached to a predetermined position such as a display case or a display shelf.

[0012]

[Effect of device]

 As described above in detail, the ultraviolet blocking cover for a fluorescent lamp of the present invention has an open annular fitting piece having spring elasticity attached to the inside of the cover body having an ultraviolet blocking function, so that the fitting piece can be attached to and detached from the fluorescent lamp. Since the cover body is fitted and covers the fluorescent lamp, the fluorescent lamp can be easily provided with an ultraviolet ray blocking function. Moreover, the UV blocking function can be added by simply covering the existing fluorescent lamp, and the replacement of the fluorescent lamp can be easily done by attaching and detaching it.
