Description

[Detailed description of the invention] The present invention relates to an improvement in an illuminated advertising light device.

Conventionally, the casing has a translucent display on the 1fj side or the front and rear sides (the entrance is 1, a lamp is placed inside, and the light from the lamp illuminates the display board surface U). Electric advertising lighting devices are already known that illuminate advertising patterns printed directly on the surface of attached advertising films or inscriptions.

However, in such devices, uneven brightness on the display panel (hereinafter referred to as "unevenness") caused by the lamps.

This is solved by increasing the number of internal lamps, so one display board has more Lf than necessary.
When I got older, my older brother's eyesight became more intense.

There was a problem that the advertising effect was reduced.

The present invention has been made with fF]W+ in view of this point, and by providing a semi-transparent eye board between the display board and the lamp, the display board can be fixed without increasing the number of lamps. An object of the present invention is to provide an illuminated advertising light device that can sufficiently exhibit advertising effects by reducing unevenness in 11α and obtaining uniform illuminance on a display surface.

The configuration of the present invention will be explained below with reference to the drawings. ]do.

In Fig. 1, reference numeral 1 denotes an electric advertising light device, which has a translucent display plate part 6°6 on the rear side of the casing 20), and lamps 4, 4 are disposed inside. There is.

Reference numeral 5 denotes a semi-transparent resin plate, which is disposed close to the lamps 4, 4 between the display plate parts 11, 3 and 6 and the lamps 4, 4. This resin plate 5 is arranged so as to be aligned with the center line of the lamp 4, and its length Ll in the vertical direction is the length Ll of the lamp 4.
It is smaller than the diameter 1-2. The resin plate 5 is made of a synthetic resin such as acrylic resin or vinyl chloride with a light transmittance of about 0 to 70%, and its size is determined as appropriate depending on the lamp 4. Selected.

Reference numerals 6 and 6 each indicate a portion of the mirror with a lit-shaped cross section, which are disposed on the upper and lower surfaces of the inside of the casing 2, and emit one beam of light from the lamps 4 to the display panel portions 6 and 6 to adjust the illuminance of the corner portion. We are trying to prevent this from decreasing. Part 6 of this Mira. For Party B, vinyl chloride (Dt, acrylic + f
It is used as a combination of 4 pieces, 4 pieces, and 1 piece with a mirror finish.

Further, the angle θ between the plate member constituting the mirror portion 6.6 and the horizontal plane is approximately θ degrees. This is the angle θ! θ
If the lamp 4.4 is turned too high, the reflected light from the lamp 4.4 will be concentrated on the course part, causing uneven brightness (brightness) than the part where the lamp 4.4 is located, while the part where the lamp 4.4 is It becomes darker than that, and there is still some unevenness in the light.
This is because j koyori(I(m 4'l) has been done.

Note that the center of the lamp 4.4 is located on the center line e-1] passing through the apex of the mirror portion 6.6. Let S be the distance 1f between the lamps 4 and 4, then the uppermost lamp 4 and the casing 2
The distance to the upper surface plate 2d and the distance between the lowermost lamp 4 and the lower surface plate 2b of the casing 2 are also S.

Next, the news regarding “Hon Departure”! (A comparison experiment conducted between the i advertising light device A and the conventional illuminated advertising light device B (with white interior) will be explained.

(Experiment/) As shown in Figure 2 (al (1) + Plate parts 6, 3

An acrylic resin plate with a thickness of 3 mm and a light transmittance of 5.5.2% is used.

The experimental results are shown in Figure 3 and the following table, as shown in Figure 3 and the following table.

The experimental results are shown in FIG. The brightness ratio of the present invention A is /: O♂, whereas the brightness ratio of the conventional method B is /:3
It is

(Actual f > 1) J) As in (experiment/), we compared the brightness of a 4A advertising light with a built-in fluorescent light, 20W x/su.

The results are shown in FIG. The device efficiency is 63% for the inventive device A and 0% for the conventional device HIqn.

The configuration as described in item 2 can reduce illumination unevenness, so if the illumination unevenness is the same, the number of lamps 4 can be reduced. In other words, in the ml related to "The analogy originates from this book", F L 3

Also, since the number of lamps 4 can be reduced,
Not only does it consume less power, making it an energy-saving key, but the internal temperature is also low, which reduces the consumption rate of electrical parts such as the Sokeso I-1 ballast.
The number of conversions of the lamp 4 is also reduced, and maintenance and management costs can be reduced.
