  Here, LED lighting fixtures are often installed in places that are out of reach, such as the ceiling, like other lighting fixtures. Therefore, it is desirable that remote control can be performed using a remote controller.

  In this case, when a plurality of LED lighting fixtures are installed, the LED lighting fixtures in a range in which a control signal transmitted from one remote controller can be received are simultaneously controlled. When performing individual control, it is necessary to assign one remote controller to each LED lighting apparatus.

  In the case of LED lighting fixtures, not only on / off and brightness control of illumination light, but also the color tone can be adjusted, so it is individually controlled compared to general lighting fixtures that can control only on / off and brightness. Often want to do.

  The subject of this invention proposes the LED lighting fixture which enabled it to control the brightness and color tone of several LED lighting fixture separately independently using one remote controller in view of such a point. There is.

In order to solve the above problems, the LED lighting apparatus of the present invention is:
An LED lamp comprising a first LED that emits light in a first color and a second LED that emits light in a second color;
An ID storage unit that stores and holds the lamp ID;
When the lamp ID stored and held in the ID storage unit is included in the control signal supplied from the outside, the brightness of the first and second LEDs is controlled based on the control signal, It is characterized by having a light control / color control part for adjusting the amount and color of illumination light of the LED lamp.

  A lamp ID is assigned to each LED lighting apparatus of the present invention. Therefore, if information indicating the lamp ID is included in the control signal from the remote controller and the control signal is enabled only when the lamp ID included in the control signal matches, one LED lighting device is provided. The remote controller can be controlled individually and independently.

  Here, the ID storage unit is set as a rewritable storage unit, and the control signal supplied from the outside includes the lamp ID stored in the ID storage unit and the lamp ID rewrite command. The ID storage unit preferably includes an ID update unit that rewrites the new lamp ID included in the control signal.

  For example, when the LED lighting apparatus is shipped or installed, the initial lamp ID is written into the ID storage unit using a dedicated lamp ID writing device. After installation in a building such as a house, an arbitrary lamp ID can be assigned to each LED luminaire according to the user's wish, which is convenient.

  In order to obtain an arbitrary illumination light, the LED lamps include a plurality of the first LEDs that emit red light as the first color and a plurality of lights that emit green light as the second color. What is necessary is just to use what provided the said 2nd LED and several 3rd LED light-emitted in blue which is a 3rd color. Of course, it is also possible to use LEDs that emit light in other colors.

  Further, as the control signal, a generally used control signal by infrared rays can be used, but a control signal by a power line carrier system may be used.

Next, the present invention is an LED remote controller that outputs a control signal for remotely controlling the LED lighting apparatus having the above-described configuration,
An ID input operation unit for inputting the lamp ID;
A light control / color control input operation unit for inputting the amount and color of illumination light of the LED lamp;
And a control signal transmission unit that generates and outputs the control signal in digital form or analog form representing the input lamp ID, dimming value, and toning value.

  As the ID input operation unit, an operation unit having an alpha bed key, a numeric keypad, or the like can be used. As the dimming / toning input operation unit, a slide-type knob for a variable volume or the like can be used. it can.

  Here, in order for the user to be able to rewrite the lamp ID assigned to each LED lighting fixture to an arbitrary lamp ID, the lamp assigned to the LED lamp in the ID input operation unit. An operation unit for inputting an ID rewriting instruction is arranged, and when the rewriting instruction is input, the control signal transmitting unit generates and outputs the control signal including a lamp ID rewriting instruction. What is necessary is just to comprise.

  In addition, the lamp ID can be an alphabet, a number, or a combination of these, but in order to make it easy to input the lamp ID, the LED lamps of a plurality of the LED lighting devices are provided. A storage unit that stores and holds the assigned lamp ID and a display unit that displays the stored lamp ID on a screen are arranged, and the ID input operation unit is one of the displayed lamp IDs. It is desirable to have a configuration in which is selected on the screen. Further, when such a storage unit is provided, the lamp IDs can be grouped and managed for each place.

  Furthermore, it is possible to arrange the LED remote controller with a pluggable insertion part such as a general household outlet so that the control signal transmission part outputs the control signal by a power line carrier system.

  If the power line conveyance system is adopted, light control and color adjustment can be performed even if the LED lighting apparatus is set in any place in the same transformer. Therefore, unlike an optical communication type remote controller, an LED luminaire that has been forgotten to be turned off, such as a remote room partitioned by a wall in a house or the like, can be remotely turned off from another room. In addition, since individual lamp IDs are set, even if there are a plurality of dwelling units in the same transformer, it does not affect the LED lighting apparatus other than the home. Furthermore, since it is possible to send control signals to each LED lighting fixture simply by plugging the LED remote controller of a general household outlet, unlike ordinary wired remote controllers, it is dedicated to send control signals. No need for wiring.

  On the other hand, the present invention relates to an LED lighting system, and includes a plurality of LED lighting fixtures having the above-described configuration and at least one LED remote controller having the above-described configuration.

  According to the present invention, since the lamp ID is assigned to each LED lighting apparatus, each LED lighting apparatus can be dimmed and toned independently by a single LED remote controller.
