FIG. 4 is a view of the light 100 as viewed from the right side in FIG. 2, FIG. 4 is a view of the rod-shaped light 100 according to the present embodiment as viewed from the left side in FIG. 2, and FIG. 6 is a view of the bar-shaped light 100 according to the present embodiment as viewed from the bottom, and FIG. 7 is a view of the bar-shaped light 100 according to the present embodiment as viewed from above. FIG. 8 is a cross-sectional view of the rod-shaped light 100 according to the present embodiment taken along line VIII-VIII in FIG.

  The rod-shaped light 100 according to the present embodiment is provided inside the body 101, and is connected to the light emitting unit 201 including a plurality of LEDs and the body 101, and can be held by hand. A holding unit 301, a power supply unit 401 provided inside the holding unit 301 and supplying power to the light emitting unit 201, a main IC 501 provided inside the holding unit 301 and controlling a light emitting condition of the light emitting unit 201, A plurality of sub-ICs 601 are provided adjacent to the plurality of LEDs and control the light-emitting conditions of the plurality of LEDs based on a main control signal from the main IC 501, and are provided outside the holding unit 301 and emit light to the main IC 501. And a switch unit 701 for giving an instruction to switch between the two.

  The body 101 has transparency so that the state of light emission of the light emitting unit 201 can be visually recognized from outside the body 101. For example, it may be made of translucent plastic or glass. In the present embodiment, it is made of plastic. In addition, the transparent portion may be only a part as long as the light emitting portion 201 can be visually recognized.

  The body part 101 includes a head part 102 that shields light emitted from the light emitting part 201. The head section 102 may use a metal piece such as aluminum. In the present embodiment, it is made of an aluminum plate. The head section 102 is provided at an upper end of the body section 101.

  Further, the head unit 102 may be configured to have a cut having a graphic shape that partially transmits light. The cut has a linear figure shape and refers to a portion through which light irradiated to the head unit 102 can be transmitted. The cut may be a figure such as a star or a crown, or a character. However, it is desirable that the cut has a width that can sufficiently suppress the luminous intensity.

  The body part 101 may further include a decorative sheet 103 inside. The decorative sheet 103 refers to a sheet through which light of a specific wavelength can pass. By transmitting light of a specific wavelength emitted from the light emitting section 201 to the decorative sheet 103, the light has an effect of appearing to have a color. Further, the decorative sheet 103 may have a plurality of irregularities on the surface and irregularly reflect light. Specific examples include cellophane, vinyl chloride, and film.

  As shown in FIG. 8, in the present embodiment, the body 101 includes an outer body 101a and an inner body 101b. Then, as described later, the decorative sheet 103 is inserted into a gap between the outer body portion 101a and the inner body portion 101b.

  The light emitting unit 201 is provided inside the body unit 101, and includes a plurality of LEDs that emit light by receiving power supply from the power supply unit 401. The LED may be one in which each LED emits a single emission color, or each LED may emit in a plurality of emission colors. In the present embodiment, an LED that emits white light is used. The plurality of LEDs are arranged in one or two rows inside the body 101 from one end to the other.

  The holding part 301 is a part for holding the rod-shaped light 100. The holding unit 301 is grasped by hand, for example. Further, a power supply unit 401 and a main IC 501 described later are provided inside the holding unit 301. The upper end of the holding unit 301 is connected to the lower end of the body unit 101.

  The holding section 301 has a strap anchor 302 for convenience in carrying. In addition, the holding unit 301 includes a power supply cover 303 on the back surface of the holding unit 301, from which the power supply unit 401 can be detached from the outside.

The power supply unit 401 is a primary battery or a secondary battery. In the case of a secondary battery, the power supply unit 401 may be configured to store power supplied from outside the power supply unit 401. Further, the power supplied from the outside may be obtained by converting sunlight into power. In the present embodiment, the battery is a dry cell such as an AA battery.

  The holding unit 301 includes a main IC 501 that controls a light emitting condition of the light emitting unit 201. The main IC 501 has a control circuit, and specifically includes a substrate circuit such as a CPU (Central Processing Unit) and an IC chip, and includes one or a plurality of processors and peripheral circuits thereof. The main IC 501 controls, for example, the light intensity, blinking speed, light emission color, and the like of the light emitting unit 201 as light emitting conditions of the light emitting unit 201.

  A plurality of light emitting units 201 are provided inside the body unit 101, and each light emitting unit 201 includes a sub IC 601 for controlling an individual LED (light emission). Note that each light emitting unit 201 does not necessarily need to be incorporated as long as the sub ICs 601 are arranged in a one-to-one correspondence so that the light emitting units 201 can be controlled. It is not necessary to weld the light emitting unit 201 and the sub IC 601 individually to the substrate when the light emitting unit 201 includes the sub IC 601 as compared with the case where the light emitting unit 201 and the sub IC 601 are individually provided.

  Thereby, a plurality of LEDs can be controlled to enrich the light emission pattern. Further, since a plurality of LEDs are provided for one sub IC 601, even if one of the LEDs is missing or damaged, the light emitting unit 201 as a whole hardly affects the light emitting pattern and the light emitting color. In particular, when a plurality of sub ICs cause the LEDs corresponding to the sub ICs to emit different emission colors, if the emission colors are missing, the light emission of the light emitting unit 201 will be less complete. Therefore, according to the present embodiment, it is possible to prevent a reduction in the degree of perfection of the light emitting unit 201 due to a defect in the emission color.

  The main IC 501 and the plurality of sub ICs 601 may be provided on the same substrate (integrally). That is, an IC base is arranged over the body 101 and the holder 301, and the main IC 501, the sub IC 601 and the LED are arranged. Thereby, the number of parts can be reduced.

  The holding unit 301 has a switch unit 701 for giving an instruction to switch the light emission condition to the main IC 501.

  In this embodiment, the light emitting pattern of the light emitting unit 201, the luminous intensity of the light emitting unit 201, and the color of the light emitting unit 201 can be switched by the number of times the switch unit 701 is pressed or the number of times the switch unit 701 is operated. In this embodiment, each time the switch unit 701 is operated, the light emitting pattern of the LED of the light emitting unit 201 changes.

  FIG. 9 is a diagram showing a state where the bar-shaped light 100 according to the present embodiment is disassembled.

  As shown in FIG. 9, the rod-shaped light 100 has a cylindrical shape in which the body portion 101 and the holding portion 301 are connected. The body part 101 has a decorative sheet 103 inserted inside the body part 101, and a head part 102 covered and fixed.

  As described above, the body 101 includes the outer body 101a and the inner body 101b, and the decorative sheet 103 is inserted into a gap between the outer body 101a and the inner body 101b.

  Further, the body portion 101 is inserted into the fixing tool 104 at the lower end, and connects the holding portion 301 including the outer holding portion 301a and the inner holding portion 301b. The connection is performed by a first metal fitting 304, a second metal fitting 305, and a plurality of screws 306a. Note that a plurality of components are arranged inside before the holding unit 301 is connected, and details will be described later.

  An inner lid 105 for fixing the head portion 102 is disposed at an upper end of the body portion 101, and forms an upper end surface of the body portion 101 together with the head portion 102.

  Next, the internal structure of the holding unit 301 will be described with reference to FIG.

  The holding unit 301 fixes the PCB board 307 including the main IC 501, the sub IC 601, and the light emitting unit 201 using the PCB fixture 308 (consisting of an upper PCB fixture 308 a and a lower PCB fixture 308 b).

  The PCB board 307 is connected to a power supply section 309 for supplying power from the power supply section 401, and is fixed together with the PCB board 307 by a PCB fixing tool 308.

  The power supply lid 303 is fixed to the holding unit 301 by a screw 310 and a screw receiver 311. By removing the screw 310, the power supply unit 401 can be replaced or charged.

  The switch unit 701 is provided at the lower end of the holding unit 301 and has a button 312 inside. When the switch unit 701 is operated, information such as the number of times and time of the operation is transmitted to the main IC 501 via the button 312.

(Control of the main IC 501)
Next, an example of control of the sub IC 601 by the main IC 501 will be described.

  The main IC 501 controls the plurality of sub-ICs 601 so that only some of the plurality of LEDs emit light at the same time. That is, the sub IC 601 is controlled so that all the LEDs are not turned on at the same time. With this configuration, power consumption per time can be suppressed.

  The main IC 501 controls the plurality of sub-ICs 601 such that a part of the plurality of LEDs sequentially emits light. That is, the sub IC 601 is controlled so that all the LEDs are not turned on at the same time. With this configuration, power consumption per time can be suppressed.

  The light emission pattern of the plurality of LEDs controls the plurality of sub ICs 601 such that the LEDs sequentially emit light from one end (upper end) in the longitudinal direction of the body portion 101 toward the other end (lower end). That is, the sub IC 601 can be controlled so that light emission of the light emitting unit flows from one end to the other. In addition, a configuration in which a part of the LED is turned on at random or a configuration in which a part of the LED is turned off at random is also applicable. According to the present embodiment, since the plurality of sub ICs 601 are individually controlled by the main IC 501, various light emission patterns can be realized while suppressing power consumption.

  Further, the main IC 501 controls the plurality of sub ICs 601 such that a part of the plurality of LEDs emits light evenly. With this configuration, the plurality of LEDs emit light evenly, so that the lifetimes of all the LEDs can be made uniform.

  The main IC 501 controls the plurality of sub-ICs 601 so that the power consumption of the power supply unit 401 becomes equal to or less than a predetermined value. Since events and concerts take a long time, light emission can be continued until the end of an event or concert by reducing power consumption. In addition, the light emission pattern may be stored in the storage area of the main IC so that the operation is switched to the long-time operation mode by operating the switch unit 701.

  The main IC 501 stores a light emission pattern in a storage area so as to control a plurality of sub-ICs 601 so as to change a time interval at which a plurality of LEDs emit light as a light emission condition every time the switch unit 701 is operated. Is also good. That is, by changing the light emission cycle of the LED, the light emission pattern can be enriched. It is preferable to control the light emission pattern so that the power consumption does not change even if the light emission cycle is changed.
