Description

[Detailed Description of the Invention] The present invention relates to a light shielding structure for preventing the display surface of a stock price report display device installed at a securities company store from becoming difficult to see due to reflection of light from a fluorescent lamp for illumination.

In order to prevent the display surface of the stock price report display device installed at the storefront of a securities company from becoming difficult to see due to the reflection of light from indoor fluorescent lamps, conventionally, for example, a wall surface 1 was installed as shown in the first figure. A housing hole 7 is provided in the ceiling surface 4 so as to be perpendicular to the display surface 2a of the display device 2 mounted on the ceiling, and the fluorescent lamp 3 is held in the socket 5 provided in the housing hole 7. Either cover the opening surface of the installation hole 7 with a light shielding plate 6 combined in a grid pattern to block the light from the fluorescent lamp 3 to the display surface 2a, or
Alternatively, the light may be covered with an opaque plastic cover to reduce light.

However, such a light-shielding structure requires extensive work on the ceiling surface 4 (drilling holes, installing the light-shielding plate 6, or installing a cover), is expensive, and reduces the brightness of the surrounding area, making the room less bright. Because they tend to be dark, they not only cause eye strain for office workers, but also have drawbacks such as the inability to easily replace fluorescent lamps and maintain and clean them.

The present invention aims to improve the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

Irregularities 14 are formed on both sides of the plate 8 to diffusely reflect outside light and the light of the fluorescent lamp 3 for illumination, and a root fitting groove 11 and a tip are formed on the upper surface of the root portion and the upper tip of the light shielding plate 9, respectively. A protruding portion 12 is provided, and a balance waist is provided on the other side covering portion 9 ₂ side of the light shielding component 13 in order to prevent the weight from shifting due to the difference in length between the covering portions 9 ₁ and 9 ₂ on both sides. administer. For example, as shown in FIGS. 5b and 5c, the thickness of the light-shielding end plate 8 and the light-shielding cover plate 9 is gradually increased from the heavier side to the smaller weight side to prevent the weight from shifting and balance the weight. . In addition, in the present invention, a balance weight such as a seat or a protrusion is attached to the portion of the light-shielding component 13 on the other side covering portion ₉₂ , for example, on the lighter side of the light-shielding end plate 8 and the light-shielding covering plate 9, so that both sides are covered. It may also be possible to prevent the weight from shifting due to the difference in length between the outer portions 9 ₁ and 9 ₂ and to balance the weight.

A required number of light shielding components 13 are used to achieve this weight balance. The number of light shielding parts 13 used is 3 fluorescent lamps.

The light that would be reflected by a and enter the eye is blocked by the light-shielding end plate 8.
The light that would be blocked by the light-shielding end plates 8a, 8b...8n, reflected on both sides of the light-shielding end plates 8a, 8b...8n, and then reflected on the display surface 2a and enter the eyes was formed on both sides of each light-shielding end plate. It is diffusely reflected by the unevenness 14,
In addition, when the fluorescent lamp 3 for illumination is held in a socket (not shown) on the ceiling surface 4 so as to be parallel to the display surface 2a as shown in FIG. 2b or c, the display surface Since the light that would be reflected by 2a and enter the eyes is blocked by the one side covering portions 9 ₁ , 9 ₁ , ... 9 1 of the light shielding plates 9 a, 9 b, ... 9 _n ,

Fig. 2b shows a case where the light shielding component of the present invention is applied to a fluorescent lamp 3 held on the ceiling surface 4 at a position relatively distant from the display surface 2a, and Fig. 2c
This is the case where the light shielding component of the present invention is applied to the fluorescent lamp 3 held on the ceiling surface 4 at a closer position than in the case of FIG. 2b. In the case of FIG. 2c, in order to effectively block light and prevent visibility due to reflection of light on the display surface 2a, when holding the light-shielding component of the present invention in the fluorescent lamp 3, the light-shielding component as shown in FIG. It is held at an angle compared to b. In the present invention, a balance weight is used to prevent the weight from shifting due to the difference in length between the covering parts 9 ₁ and 9 ₂ on both sides of the light-shielding component, thereby achieving weight balance.
When the light shielding component of the present invention is held in the desired state as shown in FIGS. can be maintained.

Further, since there is nothing blocking light between adjacent light-shielding end plates, there is no risk of reducing the brightness of the surrounding area, making the room darker than necessary, and causing eye strain.

In addition, the light-shielding end plates 8, 8a, 8b in the present invention
It goes without saying that the shape of 8n is not limited to an elliptical shape, but may be any vertically elongated shape that can block light to the display surface 2a and prevent difficulty in viewing.

As described above, according to the light shielding structure of the present invention, a required number of vertically elongated light shielding parts can be attached to the fluorescent lamp by simply inserting them, so no installation work is required. Because it requires no installation work, can be constructed with only one type of parts, and has a simple structure, it can be installed at low cost, is small and lightweight, and can be installed by holding it in close contact.
Not only is it safe as there is no risk of it falling off due to shock or vibration, but it also looks good, so it does not spoil the interior decoration. It is easy to carry, easy to assemble and disassemble, and can be done anywhere, making it easy to clean and replace the fluorescent lamp. Even if the length of a fluorescent lamp for lighting changes, there is no need to create a new one to match it, and it can be used with fluorescent lamps of any length simply by changing the number of light-shielding parts used and the length of the connection, increasing versatility. be. It is easy to install and remove, and can be installed only on fluorescent lamps that require light shielding, so it is possible to achieve appropriate light shielding. Diffuse reflection due to the unevenness formed on both sides of the end plate can be more reliably prevented, and the brightness of the room can be maintained at a desired brightness, thereby preventing eye strain for office workers. The present invention has the advantage that it can be applied regardless of whether the fluorescent lamps are arranged in a perpendicular position relative to the display surface, in a parallel position, or in a distance relation between the display surface and the fluorescent lamps.
