Description

The present disclosure relates to a power generation device that generates power using light from a lighting lamp provided indoors (hereinafter referred to as "indoor light").

A device has been proposed that is set at an arbitrary position on a window glass or indoor glass to generate electricity and store electricity using light (including indoor light) (see Patent Document 1 below). In particular, in power generation devices that use indoor light, there is a need to visualize the power generation status by turning on the light to indicate the power generation status.

JP2016-201347A

However, simply using the generated power to light a light-emitting element (for example, a light-emitting diode (LED)), the power generated by indoor light is weak, so there is a concern that there will be a loss of stored power. . On the other hand, when outputting generated power to a target device, it is essential to step down or step up the applied voltage depending on the target device, and it is inevitable that some power will be lost at this time. Therefore, it is desired to visualize the power generation status within the range of such unavoidable power loss.

The present disclosure has been made to solve the above-mentioned problems, and aims to realize visualization of power generation status within the scope of unavoidable power loss.

A power generation device according to the present disclosure includes a power generation unit that generates power using indoor light, an output end to which a mobile battery can be connected, and a power generation unit that is provided between the power generation unit and the output end, and that outputs the power from the power generation unit. A secondary battery that stores generated power and outputs the stored power to the mobile battery connected to the output end, the secondary battery operating at an operating voltage lower than the voltage of the generated power. The device includes a battery, and a light emitting element that is provided between the power generation unit and the secondary battery and emits light with a power equal to or less than a voltage step down from the voltage of the generated power to the operating voltage.

In such a power generation device, the power generation section generates power using indoor light. Although the power generated by indoor light is generally weak, the secondary battery is configured to operate at an operating voltage lower than the voltage of the generated power. Therefore, the secondary battery stores the generated power output from the power generation section, and outputs the stored power to the mobile battery connected to the output end. At this time, a voltage drop occurs from the voltage of the generated power to the operating voltage of the secondary battery, resulting in an unavoidable power loss. It emits light with less power than the step-down to the operating voltage, making it possible to visualize the power generation status. As described above, it is possible to visualize the power generation status within the range of unavoidable power loss.

According to the present disclosure, it is possible to visualize the power generation status within the range of unavoidable power loss.

It is a figure showing one example of composition of a power generation device. FIG. 3 is a diagram illustrating output control processing of accumulated power. It is a figure showing another example of composition of a power generation device. FIG. 3 is a diagram showing an example of a hardware configuration of a control unit.

Hereinafter, one embodiment of a power generation device according to the present disclosure will be described with reference to the drawings.

As shown in FIG. 1, the power generation device 1 according to the present embodiment includes a power generation section 11, a light-emitting diode (hereinafter referred to as "LED") 12, and a lithium-ion polymer secondary battery (Lithium-ion polymer secondary battery). (hereinafter referred to as "LiPo")) 13, a booster section 14, an output end section 15, and a control section 10.The functions of each section will be explained below.

The power generation section 11 is a functional section that generates power using indoor light, and the output end section 15 is an output terminal to which a mobile battery 20 can be connected. The mobile battery 20 is designed to receive power with a voltage of 5V and a current of 10A, for example, and the output end 15 outputs power with a voltage of 5V and a current of 10A boosted by a booster 14, which will be described later.

The LiPo 13 is provided between the power generation section 11 and the output end section 15, accumulates the generated power output from the power generation section 11, and outputs the accumulated power to the mobile battery 20 connected to the output end section 15. This is a battery that functions as a secondary battery. The power generated by the power generation unit 11 (that is, the power generated by indoor light) is generally weak, but the LiPo 13 operates at an operating voltage (here, for example, 3.7V) that is lower than the voltage of the generated power (here, for example, 6.7V). It is configured to work.

The LED 12 is a light-emitting element that is provided between the power generation unit 11 and the LiPo 13 and emits light with a power equal to or less than the step-down amount from the voltage of the generated power to the operating voltage of the LiPo 13 . Here, as an example, the LED 12 emits light with power related to a voltage equal to a voltage step-down (3V) from the voltage of the generated power of 6.7V to the operating voltage of the LiPo 13 of 3.7V. It should be noted that it is not essential to emit light with power related to a voltage equal to the step-down amount (3V) as described above; for example, it may be configured to emit light with power related to a voltage lower than the step-down amount (3V). Such a configuration will be described later using FIG. 3.

The step-up unit 14 is a functional unit that steps up the operating voltage of the LiPo 13 (here, for example, 3.7 V) to a predetermined output voltage (here, for example, 5 V) to be output from the output end. DC/DC converter).

The control unit 10 is a functional unit that detects the amount of electricity stored in the LiPo 13 and performs control to output the electricity accumulated in the LiPo 13 when the detected amount of electricity storage reaches a predetermined reference value.

In the power generation device 1 configured as described above, the power generation unit 11 generates power using indoor light. Although the generated power is generally weak due to indoor light, LiPo 13 operates at an operating voltage lower than the voltage of the generated power. Therefore, the LiPo 13 accumulates the generated power output from the power generation section 11 and outputs the accumulated power to the mobile battery 20 connected to the output end section 15 under the control of the control section 10 described below. At this time, a voltage drop occurs from the voltage of the generated power to the operating voltage of the LiPo 13, resulting in an unavoidable power loss.

In such a situation, the LED 12 installed between the power generation unit 11 and the LiPo 13 indicates that the power is less than the step-down amount from the voltage of the generated power to the operating voltage (here, as an example, the power related to the voltage equal to the step-down amount). Emits light. This makes it possible to visualize the power generation status.

Further, the control unit 10 executes the process shown in FIG. 2 as the output control process of the electric power accumulated in the LiPo 13. As for its execution timing, it may be executed periodically at predetermined time intervals, or it may be executed at any time in response to an execution start instruction from the operator of the power generation device 1.

As shown in FIG. 2, the control unit 10 detects the amount of electricity accumulated (amount of electricity) in the LiPo 13 (step S1), and determines whether the detected amount of electricity has reached a predetermined reference value. A judgment is made (step S2). Here, if the amount of stored power has not reached the reference value, output of the stored power is avoided, and the process of FIG. 2 ends.

On the other hand, if the amount of stored power has reached the reference value in step S2, the control unit 10 controls the LiPo 13 to output the power stored in the LiPo 13 (step S3). Thereby, the power accumulated in LiPo 13 is output from LiPo 13 and supplied to mobile battery 20 connected to output end 15 .

As explained above, in the power generation device 1, although a step-down occurs from the voltage of the generated power to the operating voltage of the secondary battery and an unavoidable power loss occurs, the light emitting element provided between the power generation section and the secondary battery However, it emits light with a power equal to or less than the step-down amount from the voltage of the generated power to the operating voltage (here, as an example, power related to a voltage equal to the step-down amount), and visualization of the power generation status is realized. That is, it is possible to visualize the power generation status within the range of unavoidable power loss.

Furthermore, the control process shown in FIG. 2 also provides the effect that weak power generated by indoor light can be appropriately supplied to the mobile battery.

Furthermore, by using a light emitting diode (LED) 12 as a "light emitting element" that emits light even when the supplied power is weak, it is possible to obtain the effect of effectively functioning even in a weak power environment. . Similarly, by using a lithium-ion polymer secondary battery (LiPo)13 as a "secondary battery" that can store electricity even if the supplied power is weak, it can be used effectively even in a weak power environment. The effect of functioning can be obtained.

Note that, as another configuration example of the power generation device 1, FIG. 3 shows a configuration in which the power generation device 1 further includes a step-down section 16 that steps down the voltage of the power generated by the power generation section 11. In the configuration of FIG. 3, the LED 12 does not use power related to a voltage equal to the voltage step down (3V) from the generated power voltage 6.7V to the operating voltage 3.7V of the LiPo 13, but a voltage lower than the voltage step down (3V). That is, the light is emitted with the power related to the voltage (lower than 6.7V) reduced by the step-down unit 16 to the operating voltage (3.7V) of the LiPo 13. The power generation device 1 may have the configuration shown in FIG. 3 as described above.
