Description

  The present invention relates to an automatic dimming projector that grasps a surrounding situation used for, for example, a pressure control device during a night operation action of an army and automatically adjusts a light amount.

Current lights (flashlights, projectors, etc.) are designed to emit a preset amount of light. When working at night, you may end up with an excessive amount of light in situations where you do not want to leak light to the surroundings (especially when the army conducts night battles).
JP 2007-157673 A

  The present invention has been made in view of the above circumstances, by grasping the surrounding situation and automatically adjusting the light amount, work is automated, adjustment errors due to individual subjective judgment (variation in skill level) is eliminated, For example, an object of the present invention is to provide an automatic dimming projector capable of raising the behavioral ability of members (average of ability).

  In order to achieve the above object, the automatic dimming projector of the present invention includes a light amount adjustment width setting circuit for setting a light type and a maximum light amount, a distance measuring circuit for measuring a distance to an object, and a light amount around the object. A sensor circuit including a light amount sensor to be measured, and a control unit that outputs a light amount control signal corresponding to the distance and the light amount measured by the sensor circuit within the range of the light type and the maximum light amount set by the light amount adjustment width setting circuit; A light emitting unit that emits light whose light amount is adjusted by a light amount control signal input from the control unit, and power supply to the light amount adjustment width setting circuit, the sensor circuit, the control unit, and the light emitting unit is started. And a switch circuit.

  The automatic dimming projector of the present invention grasps the surrounding situation and automatically adjusts the amount of light, thereby automating the work and eliminating the adjustment error (variation in skill level) due to individual subjective judgment. Can be raised (average ability).

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an explanatory diagram showing a configuration of an automatic light projector according to an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a light amount adjustment width setting circuit. The light amount adjustment width setting circuit 11 can set the type of light such as visible light or invisible infrared light, ultraviolet light, etc. according to usage conditions. For example, the maximum amount of light up to *** lx can be set. Reference numeral 12 denotes a sensor circuit, and the sensor circuit 12 includes a distance measuring circuit that measures the distance to the irradiation object and a light amount sensor that measures the amount of light around the irradiation object. In addition, you may make it the sensor circuit 12 measure the condition of irradiation objects, such as humidity.

  Reference numeral 13 denotes a control unit, which controls the type of light set by the light amount adjustment width setting circuit 11 and the state of the irradiation object such as the distance and the light amount measured by the sensor circuit 12 within the range of the maximum light amount. Output a light intensity control signal. Reference numeral 14 denotes a light emitting unit composed of a light emitting LED or a light bulb that emits invisible light (infrared light, ultraviolet light, etc.) or visible light. The light emitting unit 14 is adjusted in light amount by a light amount control signal input from the control unit 13. Emit light. Reference numeral 15 denotes a power supply unit made of a battery or a charged large-capacity capacitor. Reference numeral 16 denotes a switch circuit. The switch circuit 16 starts power supply from the power supply unit 15 to the light amount adjustment width setting circuit 11, the sensor circuit 12, the control unit 13, and the light emitting unit 14 by a switch operation.

  As shown in FIG. 1, before irradiating light from the light emitting unit 14, the light amount adjustment width setting circuit 11 sets the type of light such as visible light or invisible infrared light, ultraviolet light, and the maximum light quantity. The sensor circuit 12 measures the situation around the irradiation object such as the distance to the irradiation object and the amount of light around the irradiation object.

  When power supply from the power supply unit 15 to the light amount adjustment width setting circuit 11, the sensor circuit 12, the control unit 13, and the light emitting unit 14 is started by the switch operation of the switch circuit 16, the control unit 13 sets the light amount adjustment width. A light amount control signal corresponding to the distance and light amount measured by the sensor circuit 12 within the range of the type of light and the maximum light amount set by the setting circuit 11 is output. In this case, the control unit 13 controls to increase the light amount when the distance to the irradiation object is long, and to decrease the light amount when the distance to the irradiation object is short. In addition, when the amount of light around the irradiation object is large and bright, control is performed so as to reduce the amount of light, and when the amount of light around the irradiation object is small and dark, control is performed so that the amount of light is increased.

  A light amount control signal from the control unit 13 is input to the light emitting unit 14, and the light emitting unit 14 emits light whose light amount is automatically adjusted by the light amount control signal and irradiates the object.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.

It is composition explanatory drawing which shows the automatic light control projector which concerns on embodiment of this invention.
