As shown, the lighting device 1 according to the present invention, a plurality of light emitting diodes 10, the mounting substrate 20, the control circuit 30, the control circuit board 40 and the case 50 It becomes the structure to say.

In the luminaire 1 of the present invention, a plurality of dozens of light emitting diodes 10 are collected and used, and all of these light emitting diodes 10 have a single color and are used for simple lighting or various colors are used to change various colors. Applied where to produce.

As the light emitting diodes 10, conventional light emitting diodes emitting various well-known colors are used. Preferably, red (R), green (G), and blue (B) light emitting diodes corresponding to three primary colors of light are used. By including them all, you can create different colors.

That is, the luminaire 1 of the present invention is an indoor luminaire by providing a sufficient degree of illuminance by collectively crowding a plurality of light emitting diodes that cannot provide sufficient illuminance for indoor lighting with only one. It is intended to be applicable.

These light emitting diodes 10 are mounted densely on a dedicated mounting substrate 20 thereof. The arrangement of the light emitting diodes for compacting the mounting substrate 20 is not particularly limited, and may be arranged in an arrangement as shown in FIG. 3, for example.

For example, FIG. 3A shows an example in which a total of 19 light emitting diodes of seven red, six blue, and six green are arranged in a substantially circular shape; 3B shows an example in which a total of 24 light emitting diodes of eight red, eight blue, and eight green are arranged in a hexagonal shape extending up and down; 3C shows an example in which a total of 24 light emitting diodes of eight red, eight blue, and eight green are arranged in a substantially circular shape; 3D shows an example in which a total of 30 light emitting diodes of 10 red, 10 blue, and 10 green are arranged in a substantially circular shape; 3E shows an example in which 32 light emitting diodes of 12 red, 10 blue, and 10 green are arranged in a substantially rhombus shape; 3F shows an example in which a total of 32 light emitting diodes of 12 red, 10 blue, and 10 green are arranged at approximately six angles; It can be arranged in a variety of ways. Here, if only one light emitting diode is used for these arrangements, a monochromatic illumination without color change is obtained.

The control circuit 30 is a control circuit that produces various lightings by controlling the lighting, brightness, blink order, blink time, etc. of the light emitting diodes 10. The specific configuration of the control circuit 30 applied to the present invention is not particularly limited, and for example, a control circuit having the configuration as shown in FIG. 4 may be used.

In the example of FIG. 4, the control circuit 30 is configured to roughly include a dip switch 31, a processor 32, an output thial 33, a power supply unit 34, and the like.

The dip switch 31 is a switch for inputting an operation to be controlled, for example, timing switches 31A for collectively selecting an on / off timing period of the light emitting diode 10 and a specific color of the light emitting diode. Selection switches 31B for selecting whether the light emitting diodes are turned on or off, and function switches 31C for selecting a cycle of turning on / off for each color of the light emitting diodes.

The processor 32 receives a signal input from the dip switch 31 such as a timing switch 31A, a selection switch 31B, or a function switch 31C, determines the signal, and reads out a corresponding program. A control function of outputting a corresponding control signal to the light emitting diodes 10 is performed.

The output thial 33 is connected between the light emitting diodes of each color of the light emitting diodes 10 and a ground voltage, and is opened and closed according to the output voltage of the processor 32 to supply power to the light emitting diodes 10 of each color. It may be configured to include the switches 33A to 33C to control the.

The power supply unit 34 receives, for example, an AC (eg, AC 220V) power input from the outside and converts the DC voltage (eg, 12V) suitable for the light emitting diode 10. Of course, the AC power source can be used as it is, or AC and DC can be used in combination. Reference numeral 35, not described, refers to an oscillator that generates a timing clock signal.

Referring to the operation of the control circuit 30 by way of example, the four timing switches (31A) from the top in the dip switch 31, the more the more on the timing of the light-emitting diode 10 is turned on and off, these timings The less the switch 31A is turned on, the slower the light-emitting diode 10 is turned on and off. That is, the pulse width for controlling the output thial 33 is variable according to the setting of the timing switch 31A. When the pulse width output from the processor 32 is long, the timing of turning on and off the light emitting diode 10 is slowed. When the pulse width is short, the timing of turning on and off becomes faster.

The three selector switches 31B turn on or off the light emitting diodes 10 according to which one of them is turned on or off. That is, when the specific selection switch 31B is turned off, the processor 32 controls the switch 32 (eg, 33A) corresponding to the light emitting diode 10 of the color corresponding to the off state to turn on the light emitting diodes of the corresponding color. The light fixture 1 of the present invention becomes the light which does not use the corresponding color. In this way, the selection switch 31B may be arbitrarily adjusted so that only light emitting diodes of a specific color emit light.

In addition, the function switches 31C provided below three designate the light-on and light-off time of each light emitting diode 10, and can produce various modes of light-on, light-off, and blinking according to selection of the function switch 31C. have.

In this way, the processor 32 executes the control program to control the output thial 33 according to the selective operation of the dip switch 31, thereby controlling the light emitting diode 10.
