Description

The present invention relates to lighting devices, for example those used in concert halls.

Conventionally, various light-emitting devices have been provided that can be held and waved by the audience in time with the music or singing at concert venues and the like to enhance the entertainment value (see, for example, Patent Document 1).

JP 2018-49843 A

Incidentally, among the light emitting devices according to the prior art, there have been developed light emitting devices that can be made to have the same light emitting color or light emitting pattern as other light emitting devices.
More specifically, the color and pattern of light emitted can be changed by transmitting and receiving a control signal such as an infrared ray or an electric wave between two or more light-emitting devices.
Incidentally, at a concert venue or the like, users who own the same model of light-emitting tool may happen to be in close proximity to each other.

In such cases, when changing the light color or pattern of two or more light-emitting devices owned by a user, the light color or pattern of the light-emitting devices of other nearby users may also be changed, which is inconvenient.

Conversely, there has also been the problem that the light color or light pattern of one's own light-emitting device may be changed due to the influence (interference) of operations to change the light color or light pattern by other users in the vicinity.
An object of the present invention is to provide a light-emitting device capable of reducing interference between its own and other light-emitting devices when changing the light-emitting color or light-emitting pattern.

In order to achieve the above-mentioned object, the light-emitting device of claim 1 is a portable light-emitting device comprising: light-emitting means having a light-emitting element; control means for controlling at least one of the light emission color and light emission pattern of the light-emitting means; transmitting means for transmitting a control signal; and receiving means for receiving a control signal from an outside source, wherein the transmission and reception distance of the control signal is set to a predetermined distance around the light-emitting device, and the light-emitting element serving as the receiving means and the light-emitting element serving as the transmitting means are mounted on a substrate; and a lens member arranged to cover the upper surface of the substrate, the lens member comprising a flat portion which serves as the exit surface for the control signal emitted by the transmitting means and the light emitted by the light-emitting means and as the entrance surface for the control signal received by the receiving means, a convex portion protruding toward the light-emitting means, and legs which protrude toward the substrate from the portion where the flat portion and the convex portion are formed and which face the receiving means and the transmitting means.
Also, a light guide means for guiding light emitted from the light emitting means may be provided.
The transmission/reception distance can be adjusted by the output strength of the control signal of the transmitting means.
The transmission/reception distance can be adjusted by the reception sensitivity of the control signal of the receiving means.
The predetermined distance can be set to 100 cm or less, preferably 50 cm or less, and particularly preferably 30 cm or less.

The present invention provides a light-emitting device that can reduce interference between the light-emitting device itself and other light-emitting devices when changing the light-emitting color or light-emitting pattern.

An example of a light emitting device according to an embodiment of the present invention will be described with reference to FIGS.
(First embodiment of the light emitting device)
The functional configuration and a configuration example of the light emitting device 100A (100B) according to the present embodiment will be described with reference to Figs.
As shown in FIG. 1, in this embodiment, the two light emitting devices 100A and 100B have the same configuration.
Furthermore, the number of light-emitting devices is not limited to two as shown in FIG. 1, but three or more light-emitting devices having the same configuration may be used.
Here, FIG. 1 is a functional block diagram showing the functional configuration of the light emitting device 100A (100B), and FIG. 2 is a front view showing a first embodiment of the light emitting device 100A (100B).

A portable light-emitting device 100A (100B) that enhances the entertainment value of concerts and the like by being held and waved by the audience in time with music or singing, as shown in FIG. 1, comprises light-emitting means 10 having a light-emitting element (e.g., a three-color (R, G, B) emitting LED, etc.), light-guiding means 11 consisting of a cylindrical resin light-guiding member that guides the light emitted from the light-emitting means 10, and control means 12 consisting of a one-chip microcomputer or the like that controls at least one of the light-emitting color (e.g., one of the three colors (R, G, B) or a mixture of these colors) and the light-emitting pattern (e.g., multiple blinking patterns) of the light-emitting means 10.

It also includes an operation mode selection means 13 consisting of a switch button or the like for switching operation modes such as a mode for changing the light emission pattern or light emission color, a receiving means 14 consisting of a phototransistor or the like for receiving a control signal IR, a transmitting means 15 consisting of an infrared light emitting element or the like for transmitting the control signal IR, and a power supply unit (battery such as a dry cell) 20 for supplying power to each means.

The device also includes a storage unit 16, which is made up of a flash memory or the like, for storing at least one of the light emission color and the light emission pattern. This allows at least one of the stored light emission color and the light emission pattern to be reflected at a desired timing, thereby further enhancing entertainment value and convenience.
In addition, a confirmation light emitting means 17 may be provided, which is composed of an LED or the like, for confirming at least one of the light color and light pattern held by the holding means 16.

In this case, the confirmation light-emitting means 17 can easily confirm at least one of the light color and light pattern held by the holding means 16, improving convenience.

Here, the transmission/reception distance L1 (L2) (see Figs. 3 and 4) of the control signal IR transmitted from the transmitting means 15 is set to a predetermined distance around the light emitting device 100A (100B).
This transmission/reception distance L1 (L2) can be adjusted by, for example, increasing or decreasing the output strength of the control signal IR of the transmitting means 15.
The transmission/reception distance L1 (L2) may be adjusted by adjusting the reception sensitivity of the control signal IR of the receiving means 14.
The predetermined distance as the transmission/reception distance L1 (L2) is set to 100 cm or less, preferably 50 cm or less, and particularly preferably 30 cm or less.

This reduces interference between users' own and other users' light-emitting devices when changing the light color or light pattern. That is, even if users who own the same model of light-emitting device are in close proximity to each other at a concert venue, for example, the transmission and reception distance L1 (L2) is set to a short distance of 30 cm or less, so that when changing the light color or light pattern, it is possible to reduce the situation where the light color or light pattern of the light-emitting device of another nearby user is changed.

Here, the control means 12 may receive a control signal IR from a predetermined external device (controller, etc.) 700 via the receiving means 14, and control the light emission color and/or light emission pattern to be changed in response to this control signal.

This makes it possible to change at least one of the light emission color and the light emission pattern under control of the external device 700, thereby improving entertainment value.
The transmission and reception of the control signal IR is not limited to infrared communication, but may be performed by radio wave communication or the like.
Moreover, instead of or in addition to changing at least one of the light emission color and the light emission pattern, the vibration mode or the sound mode may be changed.
Next, the configuration of the light emitting device 100A (100B) according to the first embodiment will be described with reference to FIG.

The light-emitting device 100A (100B) is mainly composed of a housing portion 201 molded from ABS resin or the like, and a hollow cylindrical light-guiding member (light-guiding means) 11 molded from transparent or translucent acrylic resin, glass, or the like.
The light guiding means 11 is provided on its inner periphery with a film 111 having a large number of minute projections and recesses on its surface (see FIG. 3, etc.).
As a result, the light from the light emitting means 10 is diffusely reflected by the film 111 and emitted to the outside more efficiently.

The housing 201 is formed in a cylindrical shape with a bottom, and has an opening at the top. Although not shown in the figure, a female screw portion is formed on the inner periphery of the opening, and is configured to be screwed into a male screw portion formed on the outer periphery of the lower end side of the light guiding member 11.
The fixing structure of the housing 201 and the light guide member 11 is not limited to the screw structure described above, and other fixing methods such as screw fastening may be used.
Three operation switches 202 to 204 are arranged on the outer surface of the upper part of the housing 201 .

In the example shown in FIG. 2, a rectangular operation switch 202 is provided in the center, and arrow-shaped operation switches 203 and 204 are arranged on the left and right of this operation switch 202. Although not shown in the figure, an operation switch may also be provided on the back side of the housing 201.

Here, the rectangular operating switch 202 has a button (pressed portion) molded from a light-transmitting resin. By transmitting light emitted from an LED serving as confirmation light-emitting means 17 arranged in the housing 201, at least one of the light emission color and light emission pattern held (color reserved) by the holding means 16 can be easily confirmed.
Below the operation switches 202 to 204 of the housing 201, a heat exhaust hole 210 is formed to exhaust heat from a circuit board and the like, which will be described later.
A cylindrical space is formed inside the housing 201 .

As shown in FIG. 2, the housing 201 contains a substrate 320 (see FIG. 3 and FIG. 4) on which are mounted a one-chip microcomputer as the control means 12, an LED as the light emitting means 10, a light receiving element as the receiving means 14, an infrared light emitting element as the transmitting means 15, etc., a lens member 310 as an optical system member arranged to cover the upper surface of the substrate 320, a battery (dry cell, etc.) as the power supply unit 20, etc.

As shown in Figure 3, the lens member 310 is composed of a flat portion 310a which serves as the emission surface, a convex portion 310b which protrudes toward the light emitting means 10, a leg portion 310c which faces the receiving means 14, and a leg portion 310d which faces the transmitting means 15.
The lens member 310 can be integrally molded from a transparent resin such as polycarbonate, acrylic, or polystyrene.

Then, for example, by pressing either of the arrow-shaped operation switches 203 and 204, the color and light emission pattern to be held (color reserved) in the holding means 16 is selected. Then, by pressing the operation switch 202, the held color and light emission pattern are reflected in the lighting state of the LED 10.
It should be noted that pressing and holding the rectangular operation switch 202 again turns off the power.

In this way, a relatively simple pressing operation of the operation switches 202 to 204 allows the user to select a color and light emission pattern, and also allows the color and light emission pattern to be reflected on other devices (corresponding to the light-emitting device 100A in FIG. 1). This enhances entertainment value and convenience.

As shown in FIG. 3, when the light emitting device 100A and the light emitting device 100B are arranged facing each other in a state where they are both substantially perpendicular to each other, the transmission/reception distance L1 is set to, for example, 30 cm or less.
This allows the light color and light pattern to be changed by transmitting and receiving a control signal IR between the light-emitting device 100A and the light-emitting device 100B.

In addition, because the transmission and reception distance L1 is set to a short distance, it is possible to reduce interference between one's own and other light-emitting devices when changing the light color or light pattern. That is, even if users who own the same model of light-emitting device are located close to each other at a concert venue, for example, it is possible to reduce the situation in which the light color or light pattern of the light-emitting device of another nearby user is changed when changing the light color or light pattern.

Also, as shown in FIG. 4, when the light emitting device 100A is substantially vertical and the light emitting device 100B is opposed to each other in a horizontal orientation, the transmission/reception distance L2 is set to, for example, 30 cm or less.
This makes it possible to obtain the same effect as in the case shown in FIG.

(Light Emission Control Process (Part 1))
Next, an example of the process procedure of the light emission control process (part 1) executed by the light emitting devices 100A and 100B according to the first embodiment will be described with reference to the flowchart in Fig. 5. The control procedures of the light emitting device 100C according to the second embodiment and the light emitting device 100D according to the third embodiment described later are similar.
It is assumed that, at the start of this process, the light-emitting devices 100A and 100B have been powered on by a predetermined operation.

As shown in the flow chart of FIG. 5, in step S10, the LED 10 serving as the light-emitting means is turned on by a predetermined operation of the light-emitting device 100B (or 100A), and the process proceeds to step S11.
In step S11, it is determined whether or not to change the light emission pattern, etc., of the other light-emitting device 100A (or 100B).
If the determination result is "No", the process waits, and if the determination result is "Yes", the process proceeds to step S12.
In step S12, a control signal IR is transmitted to the other light-emitting device 100A (or 100B), and the process proceeds to step S13.

In step S13, it is determined whether the light-emitting device 100A (or 100B) has been powered off. If the answer is "No," the process returns to step S11, and if the answer is "Yes," the process ends.

(Light Emission Control Process (Part 2))
Next, an example of the process procedure of the light emission control process (part 2) executed by the light emitting devices 100A and 100B according to the first embodiment will be described with reference to the flowchart in Fig. 6. The control procedures of the light emitting device 100C according to the second embodiment and the light emitting device 100D according to the third embodiment described later are similar.
It is assumed that, at the start of this process, the light-emitting devices 100A and 100B have been powered on by a predetermined operation.

As shown in the flow chart of FIG. 6, in step S20, the LED 10 serving as the light-emitting means is turned on by a predetermined operation of the light-emitting device 100A (or 100B), and the process proceeds to step S21.
In step S21, it is determined whether or not a control signal IR has been received from the other light-emitting device 100B (or 100A).
If the determination result is "No", the process waits, and if the determination result is "Yes", the process proceeds to step S22.
In step S22, the light emission pattern or the like is changed based on the control signal IR, and the process proceeds to step S23.

In step S23, it is determined whether the light-emitting device 100A (or 100B) has been powered off. If the answer is "No," the process returns to step S21, and if the answer is "Yes," the process ends.

As shown in FIG. 3 and other figures, the light-emitting device 100A and the light-emitting device 100B are arranged so that the transmission/reception distance L1 (L2) of the control signal IR is, for example, 30 cm or less.
This makes it possible to reduce interference between the light emitting devices 100A (100B) when changing the light emitting color or light emitting pattern.

Therefore, for example, even if users who own the same model of light-emitting device are located nearby at a concert venue, it is possible to reduce the situation where the light color or pattern of the light-emitting device of other nearby users is changed when changing the light color or pattern.

(Second embodiment of the light emitting device)
Next, a light emitting device 100C according to a second embodiment will be described with reference to FIG.
The functional configuration of the light emitting device 100C according to the second embodiment is similar to that of the light emitting device 100A (100B) according to the first embodiment shown in Figures 1 to 3. The same components are denoted by the same reference numerals and will not be described again.

The difference from the light emitting device 100A (100B) of the first embodiment is that instead of the lens member 310 as an optical system member, a lens member 350 having an uneven Fresnel lens 350a on the front surface side is used.
The light emitting device 100C according to the second embodiment can also provide the same effects as the light emitting device 100A (100B) according to the first embodiment.

(Third embodiment of the light emitting device)
Next, a light emitting device 100D according to a third embodiment will be described with reference to FIG.
The functional configuration of the light emitting device 100D according to the third embodiment is similar to that of the light emitting device 100A (100B) according to the first embodiment shown in Figures 1 to 3. The same components are denoted by the same reference numerals and will not be described again.
The difference from the light emitting device 100A (100B) of the first embodiment is that a concave reflecting member (reflector) 360 is provided instead of the lens member 310 as an optical system member.
More specifically, a light emitting element serving as light emitting means 10 is disposed in the center of concave reflecting member 360 so as to be exposed on the front surface side.
It is preferable that the surrounding structure below the reflector 360 is transparent.
As a result, the visible light LB emitted from the light emitting means 10 is reflected by the concave reflecting member 360 and emitted to the outside from the light guiding means 11 .
In addition, a control signal IR such as an infrared ray is transmitted and received via the peripheral structure below the reflector 360.

On the other hand, below the concave reflecting member 360, there are disposed a receiving means 14 constituted by a phototransistor or the like for receiving a control signal IR, and a transmitting means 15 constituted by an infrared emitting element or the like for transmitting the control signal IR.
The receiving means 14 receives the control signal IR incident from the side of the light guiding means 11 .
Moreover, the transmitting means 15 radiates a control signal IR from the side of the light guiding means 11 toward the outside.
The light emitting device 100D according to the third embodiment can also provide the same effects as the light emitting device 100A (100B) according to the first embodiment.

(Other configuration examples of the light emitting device)
Next, another example of the configuration of the light emitting device will be described with reference to FIGS.
In addition, the same components as those of the light emitting device 100D according to the third embodiment are denoted by the same reference numerals and a duplicated description will be omitted.
In the configuration example shown in Figure 9 (a), the phototransistor constituting the receiving means 14 and the tip of the infrared light-emitting element constituting the transmitting means 15 are arranged so as to be exposed from the reflective surface of the concave reflective member (reflector) 360.
As a result, a control signal IR such as an infrared ray is transmitted and received by elements 14 and 15 whose tips are exposed from the surface of reflector 360 .
Moreover, the visible light emitted from the light emitting means 10 is reflected by the concave reflecting member 360 and emitted to the outside through the light guiding means 11 .
In addition, in the configuration example shown in Figure 9 (b), the phototransistor constituting the receiving means 14 and the infrared light-emitting element constituting the transmitting means 15 are arranged so that most of them are exposed from the reflective surface of the concave reflective member (reflector) 360.
This allows the control signal IR, such as infrared rays, to be efficiently transmitted and received by the elements 14 and 15, most of which are exposed from the surface of the reflector 360.
Moreover, the visible light emitted from the light emitting means 10 is reflected by the concave reflecting member 360 and emitted to the outside through the light guiding means 11 .

The above has been explained based on an embodiment of the light-emitting device 100A (100B) of the present invention, but the present invention is not limited to this, and the configuration of each means can be replaced with any configuration having a similar function.
For example, a channel, ID, or the like may be set in the control signal IR so that the light color or light pattern of only a specific light-emitting device can be changed.
