1. Field of the Invention
The present invention relates to a remote control with a solar-powered battery, and more particularly to remote control with a solar-powered battery which provides energy-savings and is environmentally friendly.
2. Description of the Related Art
Currently, wireless or infrared remotes are often used for controlling TVs, video machines, air conditioners, stereos, etc., as well as household appliances, garage doors, car doors, etc. These remotes are for remote control use only, but the power consumed with each use is incapable of being supplied by a small-sized, solar-powered battery. Therefore, all of these remotes require standard, non-reusable batteries, which leads to environmental pollution and waste of resources.
In contrast, solar energy is free and is a zero-emissions energy source, and thus has become one of the most popular renewable energy technologies. More and more electrical products are utilizing solar panels to convert solar energy into usable power.
Solar energy can supply power for small-sized and low-power products (such as calculators) under normal light conditions; it also can supply power for large-sized products (such as a solar-powered water boiler) under daylight conditions with a rechargeable battery for storing the resultant electrical energy.
Therefore, it is desirable to provide a remote control with a solar-powered battery to mitigate and/or obviate the aforementioned problems.
An objective of the present invention is to provide a remote control with solar-powered battery using a solar panel with a storage unit to transform light energy into electric energy for a wireless control module for remote operation, thereby providing energy savings and environmental conservation benefits.
In order to achieve the above-mentioned objectives, a remote control of the present invention with a solar-powered battery, a remote body includes the control panel. The control panel has a plurality of buttons. The solar-powered battery module is disposed in the remote and comprises the solar panel, the control unit and the storage unit. The solar panel is a rigid or flexible solar panel and is used for receiving light energy. The wireless control module disposed in the remote comprises the transmitting unit, the sensing unit and the activating unit. Therefore, the solar-powered battery module converts and stores the light energy and provides power to the wireless control module, thereby providing energy savings and environmental conservation benefits.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
A remote control with solar-powered battery of the present invention combines together solar energy receiving capabilities, electrical energy storage capabilities and wireless control capabilities for energy saving purposes.

The wireless control module 13 further comprises a protection loop, wherein when a button 110 of the control panel 11 presses the activating unit 132 of the wireless control module 13 and the press time is longer than a predetermined time limit (such as 10 seconds) the protection loop automatically stops the signal transmission to prevent waste of power, and additionally stops operations when the voltage is lower than 2.5V to prevent the battery from being damaged. Therefore, the protection loop can increase the lifetimes of both the remote and the battery.
Accordingly, the solar panel 120 receives and transforms light into storable electrical energy to replace the conventional battery within the remote 1.

The solar panel 120 is used for receiving light energy. The control unit 121 is able to transform the solar energy received by the solar panel 120 into electrical energy for the remote 1. The storage unit 122 is used for storing electrical energy converted from the light energy by the control unit 121 through the control unit 121. The storage unit 122 may be a rechargeable battery. The control unit 121 is electrically connected to the solar panel 120 and the storage unit 122 and is used for transforming light energy into electrical energy for saving in the storage unit 122.
The sensing unit 131 of the wireless control module 13 is used for sensing the press time applied to the control panel 11 (not shown) and is electrically connected to the transmitting unit 130 and the activating unit 132. The power for the wireless control module 13 is supplied by the storage unit 122 of the solar-powered battery module 12a, and the signals delivered from the activating unit 132 to the sensing unit 131 are transmitted to the target receiver via infrared light or radio frequency signals from the transmitting unit 130.
The wireless control module 13 further comprises a protection loop, wherein when a button 110 of the control panel 11 presses the activating unit 132 of the wireless control module 13 and the press time exceeds a predetermined time limit (such as 10 seconds) the protection loop automatically stops signal transmissions to prevent waste of power, and further stops operations when the voltage is lower than 2.5V to prevent the battery from being damaged. The protection loop can thus increase both the lifetime of the remote and the battery.
When light 2 shines onto the solar panel 120 of the solar energy battery module 12, the control unit 121 transforms the light energy into electrical energy and saves the electrical energy in the storage unit 122. When the activating unit 132 of the wireless control module 13 is activated by the sensing unit 131 and powered by the storage unit 122, the sensing unit 131 electrically connected to the transmitting unit 130 transmits signals to the target receiver 3 using infrared light or radio frequency signals. Therefore, the solar energy is converted into supply power for energy savings and environmental conservation effects.
In the remote control with a solar-powered battery, a remote 1 body includes the control panel 11. The control panel 11 has a plurality of buttons 110. The solar-powered battery module 12 is disposed in the remote 1 and comprises the solar panel 120, the control unit 121 and the storage unit 122. The solar panel 120 is a rigid or flexible solar panel and is used for receiving light energy. The wireless control module 13 disposed in the remote 1 comprises the transmitting unit 130, the sensing unit 131 and the activating unit 132. Therefore, the solar-powered battery module 12 converts and stores the light energy and provides power to the wireless control module 13, thereby providing energy savings and environmental conservation benefits.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
