DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small light for sensing the state of exercise and changing the state of light emission of a light emitter.

[0002]

2. Description of the Related Art Heretofore, there has been a pen-type light in which a chemiluminescent substance is sealed in a cylindrical transparent case that can be held by one hand. It emits blue-green weak light for more than a few minutes and is sufficiently visible in dark places even at distances of tens of meters. When this is given to a large audience gathered for sports and performing arts, the lights of the venue are turned off and shaken at the same time with music etc., when viewed from a distance, many light sources are shaken together, a fantastic atmosphere A certain effect can be obtained.

[0003]

However, this conventional penlight has the following problems, and its effect is still unsatisfactory. That is, since the emission color is monochromatic and the emission intensity is almost uniform, the emission is monotonic and has little change. In addition, the user of the light changes the way the light is shaken,
There is no other way to express their own intentions and emotions than to erase them. Moreover, even if the way of swinging is changed, only the way of movement of a point emitting light with a uniform color and intensity changes from the other points, and no remarkable effect can be obtained.

[0004] It is an object of the present invention to provide a light with a motion sensing function capable of changing the light emitting state according to the manner of swinging in order to enrich the means of expression by the light of the user.

[0005]

(1) A light that includes a light source that emits light by small electric energy such as an LED and emits light with a brightness that can be visually recognized from a distance of several meters or more in a dark place, further includes a motion sensor, and the motion sensor detects the light. Depending on your exercise situation,
A modulation circuit for changing at least one of the elements of the light emission state, such as the brightness, the light emission color, the blinking interval, and the afterglow time of the light source.

The light with motion sensing function of the present invention may further include at least one of the following features. (2) The motion sensor is a device capable of detecting the acceleration or the rotational angular velocity of the light. (3) The light has a rod shape that can be held and shaken with one hand, and a plurality of the light sources are provided and arranged on a side surface of the rod light.

(4) The motion sensor mainly detects lateral acceleration of the rod-shaped light. (5) The motion sensor mainly detects a lateral angular velocity of the rod-shaped light.

FIG. 1 is a sectional view showing the internal structure of a first embodiment of the present invention. Reference numeral 1 denotes a main body case which has a substantially cylindrical shape and is long in the left and right directions, and a right side (downward during normal use) of a power supply battery 2 (for example, two AA type dry batteries).
The light-emitting / control device is mounted on the left side (upward when used) of the battery compartment. The light emitting / control device is based on a circuit board 3 fixed inside the main body case 1 and includes a plurality of chip-type LEDs 4 and a motion sensor 6.
(An acceleration sensor 6a using a piezoelectric element or the like and / or an angular velocity sensor 6b suitable for a vibration gyroscope), and a circuit 7 (as shown in FIG. 2, a modulation circuit 7a and a light emitting circuit 7b, which are integrated and integrated) Are implemented or connected.

The acceleration sensor 6a has sensitivity to the acceleration in the Y-axis direction of the illustrated coordinate axes, and the angular velocity sensor 6b responds to rotational movement about the X-axis or, in the case of a biaxial angular velocity sensor, further about the Y-axis. It is mounted in the main body case so as to have sensitivity. That is, the detection sensitivity to the motion of grasping the rod-shaped main body case 1 and shaking it sideways is increased. Reference numeral 5 denotes a switch for turning on / off the power. On the left side surface of the main body case 1, there is a light emission window 1a for emitting the light of the LED 4 to the outside. Have been.

A plurality of LEDs 4 are provided, for example, to enhance the color rendering effect by being able to produce a mixed color of the three primary colors R, G, and B and other special colors (including white), or to improve the color rendering effect of the main body case 1. This is because the LEDs 4 that are directed in directions other than the front direction (upward in FIG. 1) are provided to increase the angle at which light emission can be visually recognized. Reference numeral 1b denotes a battery electrode plate with which the positive electrode of the battery contacts, and 1c denotes a spring which is pressed against the negative electrode of the battery and has a conical coil shape. 1d is a plate-shaped battery lead. The connection lines between each circuit component and the circuit 7 are not shown.

FIG. 2 is a block diagram showing an example of a circuit used in the embodiment of the present invention. FIG. 3 is a perspective view showing a state in which the main body case 1 is being used by turning on the power by grasping it by hand. In FIG. 2, the modulation circuit 7a outputs a large number of modulation control signals 60 for controlling to individually modulate the light emitting state of each light emitting circuit 7b according to various output states of the motion sensor 6. The light emitting circuit 7b for lighting each of the large number of LEDs 4 may be a conventionally known circuit using a transistor. Then, the control input terminal of the light emitting circuit 7b receives at least one of the modulation control signals 60 to control the light emitting state.

With such a structure, the main body case 1
The modulation control signal 60 changes when the way of swinging (e.g., the movement of the wrist of the grasped hand) is increased or decreased, thereby changing the light emission intensity or the temporal light emission state of each LED 4.
Therefore, when viewed from a distance, it is possible to exhibit an effect in which any of the elements of the light emission state such as the brightness of the light source, the color of the light emission, the blinking interval, the afterglow time, and the like change depending on the manner of swinging. For example, when shaken strongly and violently, the emission luminance can be increased stepwise or the emission color can be changed from red to yellow to green to blue to purple to white.

It is needless to say that the embodiment of the present invention is not limited to the above-described example. To give examples and modifications of the other embodiments, for example, it is desirable that the motion sensor is small and lightweight and has an appropriate sensitivity to motion such as arm swing, but it is preferable to use a regular accelerometer or a gyroscope. Alternatively, for example, a simple switch-type sensor in which a switch contact is turned on and off by movement of a weight such as a mercury ball can be used. The direction and sensitivity of the motion detected by the motion sensor are also arbitrary (for example, detection of acceleration in the Z direction and rotation around the Z axis).

Further, the shape of the main body case is not limited to a rod shape such as a pen type, but may be, for example, a flat shape which is easy to hold or another form. Further, another light source such as a small incandescent lamp other than the LED may be used or used together. The color and shape of light emission, the number, the direction and spread of the light beam, the arrangement on the light surface, the shape of the light emitting window, and the like are also arbitrary. Further, the manner of light emission control can be set in advance by a manual switch or the like.

[0015]

According to the present invention, at least one of LED blinking, lighting frequency, light emission intensity, simultaneous lighting number, light emission color, and the like can be changed according to the exercise state and intensity of the main body. There is an effect that a variety of expressions that were impossible in the past can be obtained. In addition, various information can be transmitted or conveyed even in the case of personal cues or collective intentions. The color can be changed collectively). Also, for example, it is possible to easily perform a human character or a picture display by light.
