Description

Energy-saving light guide

The invention relates to a kanban, in particular to a power-saving light-guiding kanban structure.

According to the kanban of the past, there are two types of traffic signs and storefront advertisements. In the case of the traffic signs, the early billboards did not have the effect of illumination or self-illumination. Therefore, although the signs can be clearly seen during the daytime, they are completely ineffective at night because they cannot be seen. Auxiliary lighting fixtures to highlight traffic signs so that road users can view them at night; in the case of storefront advertisements, it is usually a built-in fixture in a box and an advertisement on the outer surface of the cabinet. The words are clearly visible in the daytime, and the light is illuminating at night, so that consumers can recognize the words of the advertisement.

However, the above-mentioned traffic signs marked by the traffic signs, or the billboards displayed by the storefront advertisements, because the built-in lamps are illuminated by divergent light sources, it is necessary to provide a sufficient number of lamps in the box to enable the entire board to reach Uniform brightness effectively illuminates the kanban. However, as the number of luminaires increases, the power consumed during lighting increases relatively, causing problems in that electricity bills are difficult to save.

One of the objects of the present invention is to solve the above problems and provide a power-saving light-guiding kanban. The illuminating member can guide light to be emitted from the light-storing area by the light guide plate to reduce the number of lamps used, and relatively reduce power consumption. To achieve the effect of saving electricity bills.

The second object of the present invention is to solve the above problems and provide a power-saving light-guiding kanban. When the light source is used throughout the nighttime period, the battery can be intermittently powered to save power consumption, thereby reducing the number of times the battery is charged and discharged. , can increase the life of the battery.

For the purposes of the foregoing, the present invention includes:

a light guide plate, the light guide surface is formed on the surface of the light guide plate to form a light storage region in a character or a pattern, and the light guide plate is a non-light storage region outside the light storage region;

At least one illuminating member is disposed on a side of the light guide plate to emit a light source into the light guide plate;

The at least one light-storing member has a three-dimensional structure and is joined to the light-guiding pattern of the light-storable region by a corresponding character or pattern, and the at least one light-storing member is translucent and contains a luminescent powder;

a power supply device electrically connected to the at least one illuminating member to supply the illuminant power supply;

a light sensor disposed on the light absorbing member to sense light and darkness;

a time controller for setting the daytime or nighttime period, and timing;

Thereby, when the time controller is set to the nighttime period, or the light sensed by the light sensor is dim, the power supply device supplies power to the at least one illuminating member to generate the light source, and the time controller starts timing, and the light source passes through the light guide plate. The light guiding pattern is refracted to concentrate the light source and is emitted from the light storable area, so that the light absorbing member joined to the light absorbing area is transparent and bright, and the luminescent powder is simultaneously stored. When the time controller is timed for a predetermined time, the power supply device Stopping the power supply, causing at least one illuminating member to be extinguished. At this time, the illuminating member autonomously emits light by the illuminating powder until the brightness of the illuminating powder is attenuated and the light sensor again senses that the light is dim, the power supply device supplies power to the at least one illuminating member to generate the light source. By this, the cycle is set until the time controller is set to the daytime period, or the light sensor can continuously sense sufficient light source during the daylight, so that the power supply device does not supply power to the at least one illuminating member.

The energy-saving light-guiding kanban of the present invention further comprises a light sensor for sensing light and darkness. When the light sensed by the light sensor is dim, the light sensor controls the power supply device to supply power until the brightness of the luminescent powder is attenuated and the light is allowed to light. When the sensor senses dim light again, or when the light sensor continuously senses sufficient light source in the daylight, the power supply device is controlled to stop the power supply; thereby, when the light sensor senses the nighttime period, the power supply device supplies power. Giving the at least one illuminating member to generate a light source, the light source is refracted by the light guiding pattern of the light guiding plate, and the light source is concentrated and emitted from the light storable region, so that the light absorbing member joined to the light absorbing region is transparent and bright, and the luminescent powder is simultaneously stored. When the light sensor continuously senses a sufficient light source, the power supply device is controlled to stop the power supply, so that at least one of the light-emitting members is extinguished. At this time, the light-storing member emits light by the light-emitting powder, and the light sensor senses the daytime period. The power supply device is not powered to the at least one illuminating member.

The above and other objects and advantages of the present invention will be readily understood from

Referring to Figures 1 through 4, the structure of the embodiment selected for use in the present invention is for illustrative purposes only and is not limited by such structure in the patent application.

This embodiment provides a power-saving light-guide type kanban. In this embodiment, a traffic sign is taken as an example, including:

A light guide plate 1, as shown in Figures 1 to 2, is disposed in a frame A in the present embodiment. The light guide plate 1 has two display faces 10 opposite to the front and the back (only in the first to second figures). The front side is shown, and the display surface 10) is shown in FIG. 3, and each display surface 10 is formed with a light guiding pattern on the surface of the body (casting in the present embodiment), and can be composed of characters in the portion having the light guiding pattern. The light-storing region 11 is formed by the pattern, and the light guide plate 1 is a non-light-storing region 12 other than the light-storable region 11. In the present embodiment, the light-storing area 11 of each display surface 10 includes a light-guiding pattern 100 of "A" and a light-guiding pattern 101 of "B", and is represented by the word "AB". The detailed structure of the light guiding lines 100 and 101 can be seen as shown in FIG. Further, the light-storable region 11 and the non-light-storing region 12 may be formed only on one of the light guiding lines 100.

The light-emitting member 2 is a light-emitting diode in the embodiment, and is disposed on a side of the light guide plate 1 (on the side of the light guide plate 1 in the present embodiment), and emits a light source in the light guide plate 1 At this time, as shown in FIG. 3, the light passes through the refracting of the light guiding lines 100, 101, and the two display surfaces 10 are vertically exposed.

The four light-storing members 3 and 4, wherein the two light-storage members 3 correspond to the light-guiding pattern 100 and have a three-dimensional structure of "A", and the other two light-storing members 4 correspond to the light-guiding pattern 101 and have a three-dimensional structure of "B". The second light-storage member 3 is joined by the "A" in the light-storing region 11 and also on the light-guiding pattern 100 of the "A". The second light-storage member 4 is joined by the "B" in the light-storable region 11 and is also "B". On the light guiding path 101 of the word, the light storing members 3 and 4 described above are all translucent and contain luminescent powder. In the embodiment, the materials of the light-storing members 3 and 4 are acrylic, and the luminescent powder component is an aluminate.

As shown in FIG. 4, the present embodiment includes a power supply device 5, a light sensor 6, and a time controller 7. The power supply device 5 is a battery in the embodiment, which is electrically connected to the light-emitting member 2 to supply power to the light-emitting member 2; the light sensor 6 is disposed on the light-storing members 3, 4 to sense light and dark; The time controller 7 is used to set a daytime period or a nighttime period, as well as timing.

Thereby, when the time controller 7 is set to the nighttime period, or the light sensed by the light sensor 6 is dim, the power supply device 5 supplies power to the light-emitting member 2 to generate a light source, and the time controller 7 starts timing. The light source is refracted by the light guiding lines 100 and 101 of the light guide plate 1 to concentrate the light source and is emitted from the light storable region 11, so that the light absorbing members 3 and 4 joined to the light absorbing region 11 are transparent and bright, and at this time, it is clear at night. The word "AB" is detected, and the luminescent powder is simultaneously stored. When the time controller 7 counts for a predetermined time, the power supply device 5 stops supplying power, causing the illuminating member 2 to be extinguished, and at this time, the illuminating members 3, 4 are illuminated. The powder autonomously emits light until the brightness of the luminescent powder is attenuated and the light sensor 6 senses that the light is dim again, the power supply device 5 supplies power to the at least one illuminating member 2 again to generate a light source, thereby circulating until the time controller 7 is set to the daytime period. Or, the light sensor 6 can continuously sense a sufficient light source during the day of the dawn, so that the power supply device 5 does not supply power to the at least one light-emitting member 2.

In the present embodiment, the power supply device 5 is electrically connected to a solar energy storage panel 8 , and the solar energy storage panel 8 receives sunlight to generate electricity, and stores the power in the power supply device 5 . The non-light-storing region 12 of the light guide plate 1 is covered by a light-shielding member 120 that is opaque to reduce the light source of the light-emitting member 2 from being consumed in the non-light-storing region 12, and the light source is concentrated from the light-storable region 11 by the solar energy. The electric storage panel 8 stores the electric power in the electric power supply device 5, and the electric power of the light source generated by the illuminating member 2 can be supplied self-sufficiently.

From the above description, it is not difficult to find the advantages of the present invention in that:

1. Compared with the conventional kanban, the kanban of the present invention is covered by the light-shielding member 120 in the non-light-storing region 12 of the light guide plate 1. Since the light-shielding member 120 is not transparent, the light source of the illuminating member 2 can be reduced. Since it is consumed in the non-light-storing area 12, the light source can be effectively concentrated from the light guiding lines 100 and 101 of the light-storable area 11, and power consumption can be further saved.

2. In the above, the power generated by the solar energy storage panel 8 provided by the solar energy storage panel 8 can supply the power source required for the light source 2 to emit light, so that no electricity cost is required, thereby saving electricity expenses.

3. The kanban of the present invention has the design of the light guiding lines 100 and 101 on the light guiding plate 1, so that a light source with a sufficient number of lamps can be used to illuminate the light source with sufficient brightness, and the light sensor 6 and the timer are matched. 7, the power supply device 5 intermittently supplies power to the light-emitting member 2, and in the case where the light-emitting member 3, 4 does not supply power, the light-storing members 3, 4 contain the light-emitting powder and continue to emit light, so that the light-emitting member 2 is reduced. And the advantage of the intermittent power supply, the kanban of the present invention can reduce the power consumption of the power supply device 5, and can reduce the number of times the power supply device 5 is charged and discharged, and can relatively increase the service life of the power supply device 5.

The above description of the embodiments is intended to be illustrative of the invention and is not intended to limit the scope of the invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects and is in accordance with the provisions of the Patent Law.
