Summary of the Invention

Problems to be Solved by the Invention

[0005] When the state of the LED is changed by the above remote control, the remote control is not used until the state of the LED is changed next, and the remote control is not effectively used during that time.

[0006] Therefore, in view of the above problems, an object of the present invention is to provide an LED lighting device capable of using the above remote control for other purposes.

Means for Solving the Problems

[0007] To solve the above problems, the present invention provides an LED lighting device having an adjustment function to change at least one of brightness and color temperature, and the amount of adjustment by the adjustment function is controlled by a wireless remote control, wherein the remote control has a normal control mode and a grip strength detection mode, a mode switch to switch between these two modes is provided on the remote control, and a grip strength sensor for detecting grip strength is provided on the side of the remote control, and when the mode switch is set to grip strength detection mode, the adjustment function adjusts at least one of the brightness and color temperature of the LED so that the strength of the grip strength and the amount of adjustment are proportional.

[0008] In addition to functions such as dimming and color adjustment, the remote control was given the added benefit of training grip strength. Specifically, the remote control is configured to detect grip strength using a grip strength sensor. However, simply detecting grip strength would not motivate users to train their grip, so the brightness and color temperature of the LED lighting device are changed according to the grip strength.

[0009] Incidentally, when the control mode is switched to grip strength detection mode using the above mode switching switch, the state of the LED in control mode may be memorized, and the state of the LED in grip strength detection mode may be changed to a preset state, and when the control mode is switched back from grip strength detection mode, the LED may be restored to the memorized state.

[0010] Furthermore, the remote control may be equipped with a display unit that shows the absolute value of the grip strength in grip strength detection mode. [Effects of the Invention]

[0011] As is clear from the above description, the present invention enables the use of a remote control for an LED lighting device not only for dimming and color adjustment, but also for training grip strength. [Brief explanation of the drawing]

[0012] [Figure 1]A diagram showing the configuration of one embodiment of the present invention. [Figure 2] Diagram showing the appearance of the remote control. [Modes for carrying out the invention]

[0013] Referring to Figure 1, 1 is an interior space, and a ceiling light-type LED lighting device 2 is installed on the ceiling 11 of this interior space 1. In this embodiment, a ceiling light-type LED lighting device 2 is used, but a downlight-type or other type may also be used.

[0014] This LED lighting device 2 comes with a remote control 3 shown in Figure 2, which can be used to turn the LED lighting device 2 on and off and to adjust its brightness. In the following description, only dimming with this remote control 3 will be explained, but the present invention can also be applied to cases where the LED color temperature can be adjusted, i.e., when a color temperature adjustment function is provided. Furthermore, in this embodiment, the remote control 3 is configured to transmit a control signal superimposed on infrared rays, but the control signal can be superimposed on any wireless medium, such as radio waves.

[0015] Referring to Figure 2, the remote control 3 is equipped with an on / off switch 31. When the LED lighting device 2 is off, pressing this on / off switch 31 will turn on the LED lighting device 2 at maximum brightness. If you then want to lower the brightness, press the dimming switch 33 the required number of times. Instead of sending the same dimming signal from the remote control 3 each time the dimming switch 33 is pressed, the remote control 3 stores brightness levels corresponding to the number of times the dimming switch 33 has been pressed, and sends a signal corresponding to that brightness level from the remote control 3. The brightness level is displayed on the display unit 34 by increasing or decreasing the number of lit LEDs. To increase the brightness after it has been dimmed, press the dimming switch 32.

[0016] When the mode switch 36 is pressed, the remote control 3 switches from the dimming mode to the grip detection mode. When switched to the grip detection mode in this way, the brightness of the LED lighting device 2 switches to the darkest minimum level. Note that when switching modes, the brightness level in the dimming mode is stored.

[0017] Grip sensors 35 are provided on both sides of the remote control 3. This grip sensor 35 may have the same configuration as a grip strengthening device having a movable part that is biased by a spring or the like and is moved against the biasing force, but in this embodiment, no movable part is provided and the grip is detected by a strain gauge. When the grip force for holding the remote control 3 is increased, the brightness level is increased, and the increased brightness level is displayed on the display unit 34 and transmitted to the LED lighting device 2 to change the brightness of the LED lighting device 2. Therefore, if the grip force for holding the remote control 3 is increased, the brightness of the LED lighting device 2 becomes brighter in conjunction with the strength of the grip force, and if the grip force being held is weakened, the brightness of the LED lighting device 2 becomes darker. Note that if the grip force exceeds the set grip force for the maximum brightness, the brightness of the LED lighting device 2 does not change, so the absolute value of the grip force is displayed as a numerical value on the display unit 37.

[0018] When the grip training ends, pressing the mode switch 36 again returns to the dimming mode, and at that time, the brightness of the LED lighting device 2 is automatically dimmed so as to be at the brightness level in the previous dimming mode. Incidentally, when adjusting the color temperature of the LED alone or together with the brightness, control is performed so as to return to the state of the LED before the mode is switched.

[0019] Note that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the gist of the present invention.
