Description

[Detailed Description of the Invention] The present invention relates to an apparatus for packaging equipment using solar cells.

BACKGROUND OF THE INVENTION In order to save energy, a variety of recent electronic devices are equipped with solar cells that convert natural light into electrical energy. For example, remote control transmitters for television receivers have conventionally used dry batteries as their power source, making it difficult to handle as the batteries had to be replaced every six months to a year. Advances in technology such as increased efficiency and efficiency of light-emitting diodes have made it possible to save current in remote control transmitter circuits, and along with improvements in the efficiency of solar cells, solar cells have been used as a power source for remote control transmitters. It is being considered that the use of However, with the current performance of solar cells, it is impossible to operate a remote control transmitter using only solar cells, and it is necessary to use a storage battery or the like in combination.

FIG. 1 shows a circuit diagram of an example of a remote control transmitter using such a solar cell. Briefly explaining FIG. 1, when light hits several solar cells 1 connected in series, it is converted into electrical energy, charges a storage battery 3 through a diode 2, and supplies current to a remote control transmission circuit 4. Note that the diode 2 is a reverse current prevention diode for preventing the current of the storage battery 3 from flowing back into the solar cell 1 and discharging it.

By the way, such storage batteries 3 generally do not have very good self-discharge characteristics, and the longer they are stored in a warehouse, the more the capacity of the storage battery 3 decreases. At times, there is a risk that the device may not operate due to a lack of power. Further, such over-discharge of the storage battery is not good for the storage battery 4 either.

Therefore, the present invention improves the packaging equipment for equipment that uses such solar cells, and by providing a window in the packaging box to let in outside light so that the front side hits the solar cells even when packed, it can be stored in warehouses. The present invention provides a device that can compensate for self-discharge of the storage battery by supplying current from the solar cell to the storage battery even during the inventory period.

Hereinafter, an embodiment will be described with reference to FIGS. 2 and 3 showing a case where a remote control transmitter is packed together with a television receiver. Figure 2 shows
This is a side view of the state with the packaging box 5 removed, showing a remote control transmitter in which a solar cell 1 is mounted in a recess formed in a foamed polystyrene cushioning material 7 for protecting the corners of a television receiver 6. 8 is inserted. FIG. 3 shows the packaged state in which the item shown in FIG. 2 is stored in a packaging box 5.
includes a remote control transmitter 8 solar cells, 1
A window 9 is provided to let in outside light.

According to this configuration, even when the solar cell 1 is packed and stored in a warehouse, the solar cell 1 can be exposed to outside light and kept in an operating state, and the natural discharge of the storage battery 4 in the remote control 8 can be prevented. can be compensated. Therefore, the battery 4 can be kept in an appropriate state of charge at all times, allowing the purchaser to use it immediately upon unpacking, and also prevent over-discharging of the storage battery 4, thereby preventing its deterioration. can.

In the above embodiment, the case of a remote control transmitter for a television receiver has been described, but the present invention can be widely implemented in various other devices using solar cells.
