One side surface emitting type RGB LED (tip LED 415) is provided, and in addition, two control drivers 414 are provided on the back side of the LED substrate 410.

  As shown in FIG. 19, in the present embodiment, the heat radiation pad (metal pad FP) of the control driver 414 is soldered to the land portion under the component in which the nine through holes are arranged, and the GND pattern on the back surface (see FIG. 20 -BA pattern), a treatment for increasing the heat dissipation effect is performed. That is, since the control driver 414 is a sink (sink) type and heat is generated by sucking the current flowing through each LED 411, the heat generated by the control driver 414 is transferred to the GND pattern (FIG. 20) on the back surface via the EPad land pattern EP. It is possible to dissipate the heat to the (-BA pattern) and to dissipate the heat from the entire substrate. In this embodiment, the heat radiation pad (metal pad FP) and the land portion under the component are soldered as described above, but the heat radiation pad (metal pad FP) and the land portion under the component are in contact with each other to radiate heat. If possible, it does not necessarily require soldering.

By shifting to the left and right, the LEDs 411 are arranged so as not to overlap each other across the substrate. In other words, if heat-generating components are placed in an overlapping state with the substrate sandwiched between them, the heat generated by themselves and the heat generated by the components placed on top of each other will cause the temperature to rise further, causing the components to fail due to exceeding the heat-resistant temperature of the components. However, by arranging the heat-generating components so that they do not overlap with each other as in the above configuration, the risk of component failure and the risk of shortening the service life are reduced. You can

  Further, in the present embodiment, as shown in FIG. 19, FIG. 20, etc., the control driver 414 is arranged so as to be inclined by 45 degrees with respect to the LED substrate 410. With such a configuration, it is easy to route the wiring from the control driver 414, and it is not necessary to secure a large wiring space on the left and right of the control driver 414. Therefore, the width (W) of the LED substrate 410 can be reduced. Is possible.

  Further, in the present embodiment, as shown in FIG. 19, FIG. 20, etc., the land of each LED 411 is formed to be larger than a normal land within a possible range, which enhances the heat dissipation effect of each LED 411. It is configured to be.

  Further, the resist coating surface 442 of the LED substrate 410 of the present embodiment has a higher reflection efficiency than a normal green or black resist, and is a white color that exhibits high reflection efficiency for any emission color emitted by the LED 411. The resist is solid. With such a configuration, the reflectance to the front side due to the light emission of the LED 411 can be increased.

  In addition, on the surface of the white resist which is solidly coated on the resist coating surface 442 of the LED substrate 410, in addition to the component symbols 441 such as “LED11” and “LED12” as shown in FIG. A frame line indicating the mounting location of the board, a board control number, a check terminal, and letters and marks for other instructions and notes are silk-printed in yellow. As for the reflectance of the color diffusion surface, white has the highest reflectance, and yellow has the second highest reflectance. Therefore, the light emitted by the LED 411 can be reflected with high efficiency, and the component symbol 441 and the like can be appropriately recognized. Further, the white resist-coated surface 442 plays a role as a reflector, which makes it difficult to see the point light source through the light diffusion sheet 230.

  Further, as shown in the rear perspective view of FIG. 18, a control harness 412 is provided near the lower end on the rear side of the LED board 410, and a harness terminal 413 provided at the tip of the control harness 412 is provided on the rear surface of the light emission control board 420.

In this embodiment, a portion (pad) on which a resistor is mounted is provided, and jumper wiring is connected between the pads. When the resistors R1, R2, and R3 are provided, the jumper wiring is connected. It is possible to mount each resistor by cutting.

  In addition, as shown in the circuit diagram of FIG. 21A, a control harness 412 composed of five signal lines is connected to the LED board 410, and a tip end thereof is connected to a board connector 424. A harness terminal 413 is provided. Then, as shown in FIG. 21B, the harness terminal 413 is composed of a terminal corresponding to 6 pins, which is one more than the number of signal lines, and the signal line is not connected to the 6th pin.

  The board connector 424 provided on the light emission control board 420 is also composed of a 6-pin connector as shown in the circuit diagram of FIG. 21B, among which the pins 1 to 5 shown in the drawing are the LED boards. Although it is electrically connected to 410 and the pin shown in FIG. 6 is connected to the harness terminal 413, as described above (the signal line is not connected to the sixth pin of the harness terminal 413), the LED substrate 410 is Is not electrically connected. With such a configuration, even if not electrically connected, the harness terminal 413 and the board connector 424 are connected, so that an empty pin (a pin in FIG. 6) of the board connector 424 is bent, It is possible to prevent incorrect connection.

  Further, the control IC 422 of the present embodiment includes a so-called PIC (registered trademark) microcomputer, and by changing the control data and the program stored in the PIC microcomputer, the predetermined light emission mode and control can be changed, and further, It is possible to add. When rewriting, as shown in FIG. 21B, the rewriting is possible by connecting the program writer terminal 700 to the board connector 424 and performing the rewriting operation by the external device. With the characteristic configuration as described above, it is possible to rewrite the PIC microcomputer and control the light emission to the LED substrate 410 with one substrate connector 424. Note that the control IC 422 is not limited to the PIC microcomputer, and a microcontroller manufactured by another company can be used.

[Regarding modes of light emission control]
Subsequently, an example of the light emission control in the present embodiment will be described below. In the portable light 1 of the present embodiment, the control IC 422 is always energized, and by simultaneously pressing the first operation button 110 and the second operation button 120, the operation state mode and the standby mode of the light emission control are switched. By operating the first operation button 110 or the second operation button 120 after shifting to the operation state mode, it is possible to select and set a plurality of pre-stored light emission patterns to emit light. Is becoming That is, although the CPU in the control IC 422 is always energized, the CPU stops functioning by shifting to the standby mode (so-called sleep mode), so the power consumption itself is small.

  In addition, the portable light 1 of the present embodiment is capable of performing "animation light emission" by light emission control. That is, each light emitting mode of the plurality of LEDs 411 is changed with time to enable a dynamic light emitting effect, and based on the light emitting control information stored in the PIC microcomputer, the first operation button 110 and the first operation button 110. By operating the 2 operation buttons 120, various light emission modes can be changed and set as described later.

  FIG. 22 shows a list of examples of the operation modes of the light emission control in the present embodiment. That is, "control state" in the table indicates each operation state mode and standby mode in the control IC 422, and "(-)" is an operation mode in the "first operation button 110" and the "second operation button 120". "No operation" and "ON" correspond to when "push operation" is detected for 100 ms or more, and "LONG" corresponds to when "push operation" is detected for 1 second or more, that is, "long press operation". There is.

  Further, “TRIG” indicates the timing at which the pressing operation is no longer detected, that is, the “timing at which the button is once pressed and released”. This is because, for example, in the "normal mode", the "first operation button 110" is pressed to light "red", and the "first operation button 110" is "long-pressed" to adjust the brightness of the "red". In order to avoid the inconvenience that the brightness of the color you want to adjust (“red”) cannot be adjusted when you select (“LONG”), “TRIG” turns the operation button “once”. The timing of pressing and releasing is the timing of change. FIG. 22 shows a list of light emission modes and control mode transition modes according to the above detection states. The above-mentioned “ON signal” detection time is not particularly limited to “100 ms” or “1 second”, and any time can be set as appropriate.

  As shown in FIG. 22, when the LED 411 is turned off and the standby mode is set, the operating mode is activated by pressing the “first operating button 110” and the “second operating button 120” at the same time. The LED 411 emits light. On the other hand, when the "long press operation" of the "second operation button 120" is detected during the standby mode, the "custom mode" is entered and the LED 411 blinks. The "custom mode" is a mode in which animation light emission based on a repeated lighting pattern of, for example, "red" → "pink" → "yellow" can be set for a plurality of LEDs 411 according to a user's preference. The color is selected with the "operation button 110" and then the "second operation button 120" is selected. By repeating this and finally performing "long press operation" of the "second operation button 120", it is possible to set the order of the emission color of one's preference and make the animation emit light. Note that the present invention is not limited to the above-described embodiment, and the user may be allowed to select a preset emission color order.

  Subsequently, in the present embodiment, it is configured to shift to the “adjustment mode” by “long-pressing” the “first operation button 110” or the “second operation button 120” in the “normal mode” state. Has been done. Specifically, while the "light emitting color" or "animation light emission" that the user wants to adjust is being emitted by the rod-shaped light emitting unit 200, the "first operation button 110" or the "second operation button 120" is set to "long". By performing the “push operation”, it is possible to adjust the “emission color” or the “animation emission” that is emitting the light. In the “adjustment mode”, by pressing the “first operation button 110”, the emission color and brightness (luminance) of all the LEDs 411 emitting a single color are adjusted, and in the case of animation emission, the emission is performed. It is possible to adjust the speed. Then, by "long-pressing" the "first operation button 120", it is possible to set the brightness and the transition speed of the emission color (change timing from one color to another color) according to one's preference. Is. The “animation light emission” of the present embodiment is made up of a total of 6 colors of “red”, “pink”, “yellow”, “white”, “green”, and “blue”, and the transition speed of the light emission color in each LED 411 It is possible to set. Further, the emission colors are not limited to the above six colors, and it is possible to provide a function to freely set the order of the colors (color arrangement pattern) up to 30 colors. Furthermore, it is also possible to make all the emission colors of each LED 411 a single color and perform animation light emission in which the brightness (brightness) of each LED 411 is changed and the brightness (brightness) of each LED 411 is changed over time. is there.

  The operation mode in each operation state mode has been described above. However, in each operation state mode, the "first operation button 110" and the "second operation button 120" are simultaneously "long-pressed" to shift to the standby mode. Is configured to. Further, the present invention is not limited to the above embodiment, and a plurality of setting modes may be prepared and various light emitting modes may be set.

  Hereinafter, an example of the light emitting mode in the present embodiment will be described more specifically. In the portable light 1 of the present embodiment, as described above, six RGB LEDs (LEDs 411) are provided at equal intervals on the front side and the back side of one LED substrate 410, and each LED 411 of the present embodiment is , "Red", "pink", "yellow", "white", "green", and "blue" are emitted in total. In the present embodiment, a light emission pattern for lighting all 12 LEDs 411 arranged on the LED substrate 410 in a single color is stored, and by operating the first operation button 110 or the second operation button 120, six types ( It is configured so that a light emission pattern of 6 colors) can be selected. Note that the light emission mode may be blinking instead of being lit.

  It is also possible to emit a plurality of colors at the same time as the light emission pattern. For example, the six LEDs 411 on the front side emit "blue" and the six LEDs 411 on the rear side emit "red". It is also possible, and the color of the emitted light looks different depending on the viewing angle of the rod-shaped light emitting unit 200. Of course, the combination is not limited to the combination of “red” and “blue”, and other emission colors may be combined. Further, among the 12 LEDs 411 in total, 6 LEDs 411 on the grip portion 100 side and 6 LEDs 411 on the cylinder tip cover member 240 side can emit different colors. Further, it is possible not only to turn on the light but also to blink the light.

  Furthermore, it is possible to emit a total of 6 colors of "red", "pink", "yellow", "white", "green", and "blue". For example, the six LEDs 411 on the front side and the rear side This can be realized by causing the six LEDs 411 on the side to emit six colors of “red”, “pink”, “yellow”, “white”, “green”, and “blue” from the grip portion 100 side. Note that the light emission mode may be blinking instead of being lit.

  In addition, the portable light 1 of the present embodiment can be made to "animate light emission" as described above, and a dynamic light emission effect by the plurality of LEDs 411 is possible. As an example, the portable light 1 of the present embodiment can emit light as if a specific light emission color is moving in the extension direction of the rod-shaped light emitting unit 200. That is, the six LEDs 411 on the front side and the six LEDs 411 on the back side are respectively “red”, “pink”, “yellow”, “white”, “green”, and “blue” from the grip portion 100 side. The LEDs 411 are controlled to emit light based on the light emission sequence of [← "red" ← "pink" ← "yellow" ← "white" ← "green" ← "blue" ←] at predetermined time intervals. Has been done. By such light emission control, it becomes possible to visually recognize the emission color emitted by each LED 411 as if moving from the grip portion 100 side to the tube tip cover member 240 side in the rod-shaped light emitting unit 200. There is.

  Further, in another example of "animation light emission", the LEDs 411 are sequentially turned on from the state in which all the LEDs 411 are turned off to the cylinder tip cover member 240 side from the grip portion 100 side, or vice versa. By sequentially extinguishing the LEDs 411 in the state from the cylinder tip cover member 240 side to the grip portion 100 side, it is possible to produce light emission in a manner in which light is expanded or contracted in the rod-shaped light emitting unit 200. In still another example, all the LEDs 411 emit monochromatic light, and it is also possible to perform animated animation light emission in which the brightness sequentially increases (or decreases) from the grip portion 100 side to the tube tip cover member 240 side. Is. In the present embodiment, it is possible to set a total of 5 types of luminance, which is ± 2 steps from the reference luminance, and it is possible to form a gradation by the emission luminance in the extension direction of the rod-shaped light emitting unit 200.

  An example of the light emission mode in the present embodiment has been described above. However, in addition to the type of emission color, the blinking speed, the transition speed of the emission color, and in what color the LED 411 arranged at any position emits light. It can be set and controlled in various ways, and the user can operate the first operation button 110 or the second operation button 120 by storing a plurality of types of light emission patterns in the control IC 422. Can be selected.
