Description

  The present invention relates to a bar light.

  In events and festivals, there are many lamps that use penlights, lighting, etc. to enhance the production effect, and lights that attract interest through light.

  In particular, bar-shaped lights are often used to raise the venue by shaking them up in the event of nighttime events such as concerts.

  For this reason, the bar-shaped light is small and light enough to be swung by hand, and needs to have sufficient illuminance and sufficient power to maintain it.

  Techniques related to recent bar lights are disclosed in Patent Document 1 and Patent Document 2.

  Patent Document 1 is provided with a light emitting diode that emits each color constituting the three primary colors of light, and each light emitting diode is individually controlled so that the light source unit can emit light in an arbitrary color. Techniques related to this are disclosed.

  Patent Document 2 discloses a technique related to a rod-shaped light that can be reduced in weight and size by using an electric board that indicates a light emitting element as one pole of a light emitting tool.

JP 2000-90702 A JP-A-9-282902

  However, since the bar-shaped lights described in Patent Documents 1 and 2 have sufficient illuminance, when used in a concert or the like, the illuminance of the light beam forward is high due to the directivity of light, and the front of the bar-shaped light is high. There was a danger that a person who was exposed to the light from the front would hurt their eyes.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a safe bar light that suppresses the illuminance of a light beam forward.

  A rod-shaped light according to the present invention includes a cylindrical body part, a light-emitting part that is provided inside the body part, emits light, a head part that is provided at the front end of the body part and shields light emitted from the light-emitting part, and the body A holding unit that is connected to the unit and is grasped by a hand, and a power supply unit that is provided inside the holding unit and supplies power to the light emitting unit.

  The “body part” means a part having transparency so that the state of light emission of the light emitting part can be confirmed from the outside. For example, it may be made of translucent plastic or glass. Further, the body part may further include a decorative sheet on the inner side.

  The “decorative sheet” refers to a sheet that can transmit light of a specific wavelength. By transmitting the light of a specific wavelength emitted from the light emitting part to the decorative sheet, there is an effect of making the light appear to have a color. Further, the decorative sheet may have a plurality of irregularities on the surface and diffusely reflect light. Specific examples include cellophane, vinyl chloride, and film.

  Further, the body part may be configured to be detachable from the holding part.

  The “light emitting unit” refers to a unit that emits light upon receiving power from a power source unit. Specific examples include a light emitting diode. Each light emitter may emit light in a single light emission color, or each light emitter may emit light in a plurality of light emission colors.

  The “head portion” shields light emitted from the light emitting portion, and for example, a metal piece such as aluminum may be used. Further, the head portion may have a cut portion having a graphic shape that partially transmits light.

  The “cut portion” has a linear figure shape and refers to a portion through which light irradiated to the head portion can be transmitted. The cut portion may be a figure such as a star or a crown, or a character. However, it is desirable that the cut portion has a width that can sufficiently suppress the illuminance.

  “Holding part” refers to a part for the user to hold the bar light. The holding part may have a protrusion on which a strap or the like can be attached. The holding unit may further include a control unit that controls the light emission conditions of the light emitting unit.

  “Power supply unit” refers to a unit that supplies power to the light emitting unit. Specific examples include dry batteries and button batteries. The power supply unit is preferably one that stores electric power inside, such as the above-described dry cell, but may be connected to an external power source and supplied with power, such as a battery.

  The “control unit” refers to one having a control circuit, and specifically includes a substrate circuit such as a CPU or an IC chip. The control unit controls, for example, the illuminance, blinking speed, blinking color, and the like of the light emitting unit as the light emitting conditions of the light emitting unit.

  The holding unit may further include a switch unit that gives a light emission condition switching instruction to the control unit.

  A rod-shaped light according to the present invention includes a cylindrical body part, a light emitting part that is provided inside the body part and emits light, a head part that is provided at the front end of the body part and shields light emitted from the light emitting part, The head unit shields the light emitted by the light emitting unit when it is provided with a holding unit that is connected to the body unit and grasped by a hand, and a power supply unit that is provided inside the holding unit and supplies power to the light emitting unit. By doing so, it becomes possible to suppress the illuminance of the light beam forward.

  In addition, when the head portion includes a cut portion having a graphic shape that partially transmits light, it is possible to make characters and figures appear on the head portion while suppressing the illuminance of light emission.

  Further, when the body portion is further provided with a decorative sheet on the inner side, it is possible to impart a decorative property to the light emitted from the side surface of the body portion.

  In addition, when the body part is detachable from the holding part, it is possible to easily replace the deteriorated light emitting part or a head part having a different shape of the cut part.

  Further, when the holding unit further includes a control unit that controls the light emission conditions of the light emitting unit, more light emission patterns can be realized.

  Further, when the holding unit further includes a switch unit that gives an instruction to switch the light emission condition to the control unit, the user can freely select a light emission pattern.
