Description

Surface emitting unit {omitted}

The present invention relates to a surface light emitting unit (Unit). In particular, the present invention relates to a surface light emitting unit that is capable of emitting light from a surface by laying on a floor surface or a wall surface of a building.

There is a recessed type light emitting device that is embedded in the floor surface of a shopping mall, store, food and beverage store, etc. and emits light from the floor surface. Contributes to.

Since a conventional light emitting device is buried in the floor of a building, it is common to be constructed at the time of construction of a building, and when it is installed on an existing building floor, it is necessary to construct a mentally or economically burdened work. For this reason, even if you want to produce a directing effect and decoration effect by light in an event such as a store or an exhibition venue with a short schedule and period of time, a conventional light emitting device could not respond promptly and respond appropriately to the wishes of the organizer. There was a disadvantage.

Recently, lighting apparatuses that can realize floor lighting and install on existing floors have been proposed. The floor lighting device includes a thin casing with an open top and a plate-shaped reinforced plastic material disposed in an upper opening of the casing, and a plate-shaped light diffusing member disposed below. And a light source such as a fluorescent lamp that irradiates the light diffusing member. As a power source for emitting a light source, a general general power source is used.

The above lighting device is composed of a reinforcing plastic material, a light diffusing member, and a light source stacked up and down in a casing, and the casing is relatively large and the upper surface of the lighting device, that is, substantially As a result, there was a problem that the floor of the building was relatively high. Due to this problem, the height of the ceiling and the entrance of the place where the lighting device was installed was limited, and the height between the place where the lighting device was installed and the place where the lighting device was not placed was remarkable. There was a defect that caused inconvenience to pedestrians.

In addition, the conventional lighting device is a general light bulb, the light is emitted only in one color was not enough to produce the fantasy (Fantasy) and Illusion (Illusion) of the light, there was a limit to inspiring the interest of the customer. That is, it was not possible to change and implement any other color over time.

In addition, in the conventional lighting device, when the casing is formed into a rectangular parallelepiped and the plurality of lighting devices are arranged in the longitudinal direction and the lateral direction, a large-scale overall lighting system is constructed in response to the floor area to be installed. In this case, however, each lighting device must be connected with an electric line, and each wire must be connected to a commercial electrical outlet. There was a problem in the work efficiency due to the congestion of separating and wiring a plurality of wires. In addition, the reinforcement plastic installed in the opening of the casing is easily damaged by the sharp parts such as heel shoes and umbrellas of the pedestrians, and is changed to semi-permeable in the course of time, resulting in the problem that the aesthetics are halved while the brightness is halved. If tempered glass is used as a substitute for tempered plastic, it can be suppressed from being damaged by semi-permeability due to damage, but glass may become slippery due to the addition of moisture in rainy weather, causing pedestrians to fall.

The present invention improves the shortcomings of the prior art and at the same time can realize the floor lighting simply and extremely easily, and can produce a fantasy of light and the like, and can be laid on the existing floor. It is to provide a lighting unit of a unit.

The surface light emitting unit according to claim 1 includes a plate-shaped surface member through which light can pass, a plate-shaped light guide plate built into the bottom surface of the surface member, and a plurality of light emitting diodes having different light emitting colors from each other on both sides of the light guide plate. Electric light that is turned on or flashes from the light-diffusing member and the electro-light emitting means, which are installed on the bottom side of the light-emitting means having the light guide means and the light guide plate to diffuse and reflect the light passing through the light guide plate. (Previous light emitting diodes are provided with a light emitting color selection means and an electric surface member in the upper opening, and an electric light guide plate, an electric light emitting means, and an electric light diffusion reflecting member. Others installed adjacent to the casing of a rectangular parallelepiped shape that can be appropriately installed on a mounting surface such as a floor or a wall. It is provided with a connecting portion connectable with respect to other surface-emitting unit.

As the "light diffusing reflection member", a white plate may be exemplified, and a white fluorescent substance may be dispersedly provided between the light diffusing reflection member and the light guide plate.

Therefore, in the surface light emitting unit according to the invention of claim 1, since light emitting means having light emitting diodes is provided on the side of the light guide plate, light of the light emitting diode passes through the inside of the light guide plate and is diffused to the bottom of the light guide plate (rear side). When the member is irradiated, light is diffused from the light diffusion reflecting member so that some light is emitted from the upper surface (surface) of the light guide plate, and the light is emitted to the outside through the surface member disposed in the upper opening of the casing. . That is, the light guide plate functions as a surface light source so that light uniformly covers the entire surface of the surface member.

In particular, since the light emitting means has a plurality of light emitting diodes having mutually different light emitting colors, light emitting diodes which are turned on or flashing are selected according to the light emitting color selection means, so that light emitted from the selected light emitting diodes is radiated to the outside. For example, when three types of light emitting diodes that display red (R), green (G), and blue light (B) light of a light emitting diode are designed and installed, the light of the light emitting diode is combined to a desired color. Light is emitted from the surface member. In addition, the emission color of the light is changed by switching the light emitting diodes to be switched to each other, that is, changing the states of lighting and blinking.

A plurality of surface light emitting units can be combined on a planar surface according to the connection between the adjacent surface light emitting units. In particular, since the number of surface-emitting units that can be combined is not limited, it can be configured to correspond to the width and structure of the floor area required for installation.

In the case of dispersing the white phosphor between the light diffusing reflection member and the light guide plate, the light of the light emitting diode passes through the inside of the light guide plate and irradiates the fluorescent white material at the bottom of the light guide plate, and the fluorescent white light receives the light of the light emitting diode and Fluoresces of the corresponding color. The portion where no white fluorescent substance is installed is responded at a predetermined wavelength to exhibit a corresponding fluorescence emission. In this manner, the brightness of the light guide plate is increased. That is, the light passing through the portion where the white phosphor is not distributed and the light passing through the white phosphor irradiate the optical reflecting member in the bottom of the light guide plate.

In other words, when one surface light emitting unit is set as the main device, the microcomputer embedded in the surface light emitting unit recognizes that the self is a main device and transmits light emission information to the other surface light emitting unit. When another surface emitting unit is set to a boil, the microcomputer embedded in the surface emitting unit recognizes that it is a boil and reads information transmitted from the set surface emitting unit. According to this, the state of lighting or blinking of the light emitting means is controlled. Therefore, even when a plurality of surface light emitting units are installed, when one surface light emitting unit is selected and its surface light emitting unit is set to the main, and connected to another surface light emitting unit, the state of lighting or flashing depends on the previously set information. Lighting is implemented in a pattern.

As a result, even if water or a liquid of food or the like is introduced into the casing 4 from the upper surface of the light emitting unit 1 and enters the outer bottom through the side, the circuit box 14 is prevented from inflow of water. Is prevented.

As shown in Fig. 4 and Fig. 5, the transparent glass 6 was made of a colorless transparent glass having a thickness of 8 mm. The projections 19 are formed of a plurality of fine glass powder lump particles on the surface. This projection 19 exhibits proper resistance to the glass surface to prevent slipping of pedestrians and the like. Although the size of the projection 19 is not specifically limited, an effective slip prevention can be expected by setting it to about 0.5 mm to 3 mm.

Here, reference is made to the manufacturing method of the transparent glass plate 6 having the projections 19. The fine glass adhesive is applied to the surface of the glass plate in a predetermined pattern, and then the fine glass powder having a softening point lower than that of the plate glass is dispersed and adhered to the fine glass powder adhesive. After confirming the adhesion to the adhesive for the micro glass powder, the micro glass powder is removed using a means such as Vacuum. Thereafter, the glass plate with the fine glass powder is reversed with heat to fuse the fine glass powder on the surface of the glass plate and then cool.

More specifically, the light emitting diodes 11 in the stacking direction are mounted on a substrate without being pressed against each other, and they are installed so as to be aligned with each other in the vertical direction. For example, the red diodes 23 may be used as dichroic emitting means. The green diodes 24 and the blue diodes 25 are formed in a stack so that the green diodes 24 and the blue diodes 25 are positioned at an oblique bottom. In such a configuration, the three-color light emitting diodes 11 are arranged in a single row in a manner in which the light emitting diodes 11 are equally arranged on the side surfaces of the light guide plate 8. In contrast, the interval between the light emitting diodes 11 of the same color is narrowed. Referring to FIG. 6, it can be seen that the distance of Da from the street is shorter than my distance from the street.

The entirety of the control device 34 including the CPU 35, the control switch 41, and the light emission color selection switch 47 mentioned here corresponds to the light emission color selection means of the present invention.

9 is an enlarged perspective view showing the configuration of the base metal tool 3 according to the present invention.

The base metal tool (3), which is a bonding tool between the surface emitting units (1), A support plate 49 for supporting the casing 4 by grounding the adjacent surface light emitting unit 1, which is grounded on the back mounting surface, to the outer bottom surface of the four corners 15 of the fixing plate 48 and the casing 4 as a binding and fixing tool. ) It consisted of the bolt-shaped rotation shaft 51 which had an axle above the fixed plate 48, and was formed in the center of the support plate 49. As shown in FIG. In other words, if the floor lighting system 2 is to be permanently installed, it is preferable to fix the fixing plate 48 to the mounting surface, but in the case of temporary or temporary installation, the fixing plate 48 may not be fixed. In this case, there is no congestion that damages the floor, so it can be used freely.

The support plate 49 is formed with four hemispherical protrusions 50 facing upwards. It is a part that can be joined to the hemispherical protrusions formed on the outer bottom face of the four corners 15 of the casing 4.

The protrusion 50 and the convex part which are provided on the support plate 49 which support the casing 4 are combined.

The adjustment of the height between the adjacent casings 4 is to rotate the support plate 49 clockwise or counterclockwise to match the height of each other, and then combine.

A jaw portion 51a is formed at the top end of the rotating shaft 51 at a position higher than the top surface of the protrusion 16 formed at the four corners 15 of the casing opening 4. The part 51a is for fixing the knit fastener 52 after joining the casing 4. That is, the fastener 52 is fixed to the upper end of the rotation shaft 51 in the state where the casing 4 is disposed on the upper surface of the support plate 49. When the fastener 52 rotates, the fastener 52 is rotated. The bottom surface of the fastener 52 is joined to the upper surface of the protruding portion 16 while being fixed by being locked by the jaw portion 51a.

As mentioned above, movement of the casing 4 is prohibited by the fastener 52, and the floating phenomenon in the four corners 15 of the casing 4 by the support plate 49 is prohibited. Here, the combination of the base metal tool 3, the fastener 52 and the protrusion 16 corresponds to the connection of the present invention.

Next, the light emission operation with respect to the surface light emitting unit 1 will be described. As shown in FIG. 5, the light emitted from the light emitting means 12 passes through the inside of the transparent light guide plate 8. A plurality of fluorescent white bodies 21 are provided on the back surface. When a part of light irradiates the fluorescent white bodies 21, the fluorescent white bodies 21 exhibit fluorescent colors of the corresponding colors in response to a predetermined wavelength. In the above configuration, the brightness of the light guide plate 8 is increased. In addition, when the light passing through the fluorescent white member 21 is irradiated to the light diffusing reflecting member 9 disposed under the steel plate 8, the light diffusing reflecting member 9 reflects light and diffuses around. Some of the light is emitted to the surface of the light guide plate 8.

Light emitted to the surface of the light guide plate 8 passes through the transparent resin diffusion plate 7 and the transparent glass plate 6 and is emitted outside the casing 4. At this time, the transparent resin diffusion plate 7 Since the light is diffused, the light from the surface of the transparent glass plate 6 can be attached to the contour of the interior of the interior of the transparent glass plate 6, and the light on the surface of the light guide plate 8 can be emitted.

Therefore, the light as the surface light source of the light guide plate 8 and the light uniform to the entire area of the transparent glass plate 6 are used.

The light emitting means 12 includes red diodes 23, green diodes 24, and blue diodes 25, which are three primary colors of light, and controls red, green, blue, and combinations of the colors. The full color light generated by the radiation is emitted to the transparent glass plate 6. In particular, since the light emitting diodes 11 are stacked in two rows, and the three-color light emitting diodes 11 are uniformly arranged on the side surface of the light guide plate 8, a light emitting state without any difference in contrast is possible.

8, the CPU 35 provided in the surface light emitting unit 1 as a flowchart which shows the flow of an operation is demonstrated based on FIG. The CPU 35 determines the state of the main slave switching switch 40 when the power switch is ON (step is YES), and if it is set in the cycle (YES to step S2), steps S3 to Step S7 executes the processing.

In this case, the process of step S2 corresponds to the judging means of the present invention.

In either case, in step S3, it is determined whether at least one of the light emission color selection switch 47, that is, the red selection switch 42, the green selection switch 43, and the blue selection switch 44 is in an ON state, that is, whether or not it is determined. In the ON state (YES in step S3), the light emitting diode 11 is turned on in response to the light emission color selection switch 47 in the ON state (step S4). When the red selection switch 42 and the green selection switch 43 are in the ON state at the same time, the red diode 23 and the green diode 24 are controlled and turned on. Therefore, when all the light emission color selection switches 47 are in the ON state at the same time, the red diodes 23, the green diodes 24, and the blue diodes 25 are all controlled and turned on.

In addition, the CPU 35 can emit the other surface light emitting unit 1 in the same color as its own emission color. The command 35 transmits a command (light emission information) to the other surface light emitting unit 1 (step S5). . In other words, if the power switch is in the OFF state (NO in step S8), the processing returns to step S2. That is, when there is no switching between the main / species switching switch 40 and the light emission color selection switch 47, the processing of steps S4 and S5 is repeated. Although not shown in the figure, during the processing of Steps S4 and S5, if a person is near or a physical change occurs, an emergency process proceeds to emit light in a specific pattern. do.

In either case, when the light emission color selection suite 27 is not selected in step S3 (NO), the light emitting diode 11 is turned on or blinking due to the light emission pattern set by the control switch 41. (Step S6) After that, it moves to step S5, and is processed. In the case where the other surface light emitting unit 1 is to emit light with the same light emitting pattern as the self or the light emitting pattern due to the address (placement location) of the surface light emitting unit 1, the light emitting information of the other surface light emitting unit 1 Send a command. That is, when there is no switching between the main / species switching switch 40 and the light emission color selection switch 47, the floor lighting system according to the lighting pattern set by repeating the processing of the following step S5 of step S6 ( 2) to control the whole. For example, in the whole surface light emitting unit 1, it may flash in order of red, yellow, green, cyan (Syan), blue, green light (Magenta), and white, and this can be repeated.

In addition, when the master / slave switch 40 is set to the slave (NO in step S2), it is attributable to the command transmitted from the master. The light emitting diodes 11 are turned on or flashing (step S7). For example, when the emission color of the main device is constant, the light emitting diode 11 is controlled to have the same emission color as the main device, and the emission color is to be changed due to the lighting pattern of the main device. In this case, the light emitting diodes 11 are controlled in accordance with the pattern. Subsequently, the processing proceeds to step S5 where a command (that is, a command) that has been processed and transmitted from the main device, that is, a command that has been received, is transmitted to another adjacent surface light emitting unit 1. In other words, when the signal lines of the plurality of surface light emitting units 1 are connected in series, a command is simultaneously transmitted from the surface light emitting unit 1 set to the main device to another surface light emitting unit 1. In this case, in the surface light emitting unit 1 set in the boil, a command received via a signal line is distributed to another surface light emitting unit 1 via another signal line. In other words, when wirelessly transmitting / receiving a command, it is not necessary to do this. Even if the power switch is in the OFF state, the processing of steps S7 and S5 is repeated until the main / slave switching switch 40 is switched. In this case, the processing of steps S3 to S7 corresponds to the light emission control means of the present invention.
