DETAILED DESCRIPTION OF THE INVENTION

[0020] As shown in FIGS. 1 through 9, a smart control system for a solar brick 1 is sought to be protected by the present invention based on electronic circuitry embedded with a microcontroller 50 including firmware and an NFC interface circuit 58 located in an NFC sensitive area 55, and an electronic integrated circuit with an accelerometer 60. Such a structural electronic design and arrangement enables movement and position sensing and status determination and function programming through a mobile or specific device of the solar brick. The smart control system of the solar brick also includes a LED driver 70 that is coupled and controlled by the microcontroller 50 and that is capable of setting or adjusting one or more technical functional and operating parameters of one or more RGB-type LEDs 80, and one or more RGB-type LEDs 80 coupled and controlled by the LED driver 70 in accordance to the one or more technical operating parameters set or adjusted through the mobile or specific device.

[0021] The microcontroller 50 may include a 32-bit ARM microcontroller, but the microcontroller to be used by the smart control system may include any type of embedded communications, industrial or consumer device microcontroller.

[0022] The capabilities directed to movement and position sensing are possible because the electronic integrated circuit with the accelerometer 60 is coupled to the microcontroller 50. The position and movement sensing capabilities of the accelerometer 60 coupled to the microcontroller 50 allow the smart control system to power the solar brick on and off during transportation to prevent the batteries of the solar brick from being discharged in the typical horizontal transportation position. Likewise, the accelerometer 60 coupled to the microcontroller 50 of the solar brick 1 also allows the solar brick 1 to be used and operated in different angles, beyond that of a horizontal position plane installation, such as in a vertical position or inclined position.

[0023] Using the accelerometer 60 instead of a key preventing the operation and functioning of the solar brick 1 in a determined position, the microcontroller 50 tied to the accelerometer 60 determines the angular position of the solar brick 1. On top of the angular position, the accelerometer 60 is also able to determine if a casing 10 of the solar brick 1 has come to a complete stop or is moving, sensing if the brick is installed or being transported regardless of its position. With this novel design and arrangement, the shortcomings encountered in conventional solar bricks is overcome, regardless of the position of the solar brick 1, as the solar brick's configuration and arrangement senses if the solar brick 1 is being transported and can be used in different installation angles.

[0024] The accelerometer 60 may be a 3-axis accelerometer. The electronic integrated circuit of the accelerometer 60 may further be MEMS-technology based and may have internally 3 components that respond to and sense solar brick movement and position once installed in 3 possible axes X, Y and Z.

[0025] The component of the smart control system of the solar brick that enables it to operate the solar brick properly and effectively is its specific firmware. A firmware is a software specifically developed for a hardware component which, in this case, is for and found in the microcontroller 50. The firmware is the one component which possesses the information related to the ideal battery charge level of the solar brick 1 and its operation and control capabilities, as well as how much energy can be obtained from a photovoltaic solar cell and the best operation mode.

[0026] The solution found and embedded in the firmware may be an algorithm using Maximum Power Point Tracking (MPPT), which is a computational technique which is usually found only at the hardware level in a conventional solar brick. In the smart control system of the solar brick of the present invention, the MPPT algorithm is found and embedded in the firmware. In addition, the MPPT algorithm is conditioned and used for other operating and control parameters and factors such as actual battery energy level, making it a much more efficient solution.

[0027] The NFC interface circuit 58 located in the NFC sensitive area 55 included in the microcontroller 50 provides the user access to operational and control parameter information of the solar brick 1 such as actual battery level, illumination mode and LED colors used. To access said information, a user may use an NFC-enabled communication mobile or specific device or may prefer to use a specific reader.

[0028] By having NFC-enabled communication capabilities, the smart control system of the solar brick 1 allows the operation of the solar brick 1 to be customized after installing the solar brick 1 in a horizontal, vertical or inclined position. The user can, through its smart control system, configure the solar brick and adjust its operational mode/conditions to cater to different environments or different situations such as social events, special dates, to highlight architectural contours or even act as safety/emergency lighting.

[0029] Another common factor in conventional solar bricks is the white color lighting/illumination or any other chosen lighting/illumination color. More specifically, conventional solar bricks have fixed colors as the user operates these conventional solar bricks always with the same fixed color provided by the manufacturer. The smart control system of the solar brick 1 of the present invention overcomes the previous shortcomings as it has RGB-type LEDs. The RGB-type LEDs have 3 components or internal LEDs, one for each color being: red, green and blue. The RGB-type LEDs can be powered independently generating the 3 primary colors or with modulated power in each of the primary colors enabling possibly a great number of color schemes and several resulting white shades.

[0030] In another embodiment of the smart control system of the solar brick of the present invention, the smart control system may include a temperature sensor 90 that is coupled to the microcontroller 50 and is capable of feeding the microcontroller 50 with temperature data of the solar brick.

[0031] As shown in FIGS. 1 through 9, a solar brick 1 with movement, position sensor and NFC communication capabilities is provided and sought to be protected, the solar brick 1 comprising one or more photovoltaic cells 20 capable of converting solar energy into electric energy; a photovoltaic circuit 30 that is coupled to the one or more photovoltaic cells 20; one or more rechargeable batteries 40 that are coupled to the photovoltaic circuit 30; an accelerometer 60 that senses the movement and position of the solar brick; a microcontroller 50 that is coupled to the accelerometer 60 and fed with movement and position data of the solar brick 1 from the accelerometer 60, the microcontroller 50 includes firmware and an NFC interface circuit 58 located in an NFC sensitive area 55 and which has NFC-enabled communication capabilities enabling status determination and function and operational programming of the solar brick through a mobile or specific device; a LED 70 driver that is coupled and controlled by the microcontroller 50 and that is capable of setting or adjusting one or more technical functional and operating parameters of one or more RGB-type LEDs 80; one or more RGB-type LEDs 80 coupled and controlled by the LED driver 70 in accordance to the one or more technical operating parameters set or adjusted through the mobile or specific device; and a casing 10 that houses the one or more photovoltaic cells 20, the one or more rechargeable batteries 40, the photovoltaic circuit 30, the accelerometer 60, the microcontroller 50 including the firmware and the NFC interface circuit 58 located in the NFC sensitive area 55, the LED driver 70, and the one or more RGB-type LEDs 80.

[0032] In different embodiments of the solar brick of the present invention, the solar brick 1 may include one or more high endurance rechargeable batteries. Likewise, the casing 10 of the solar brick 1 may be waterproof and completely sealed. In addition, the casing 10 of the solar brick 1 may be made of durable glass which is resistant to vehicular traffic. Similarly, the casing 10 may also be made of translucid polymers (like, but not limited to, polycarbonate, polyethylene, polypropylene), resins, foam, fiberglass, natural stone, quartz, inter alia.

[0033] In another embodiment of the solar brick of the present invention, the solar brick 1 may include a temperature sensor 90 that is coupled to the microcontroller 50 and is capable of feeding the microcontroller 50 with temperature data of the solar brick 1.

[0034] The solar brick 1 and its smart control system are compatible with, but not limited to, operating systems such as Android and iPhone, can be coupled easily to a PC or laptop, and all of its status parameters can be visualized such as power level, programmed parameters, solar energy actual level, internal temperature, inter alia. With exposure to sunlight, the one or more photovoltaic cells 20 generate energy which is managed by the microcontroller 50 for charging the one or more rechargeable batteries 40 in accordance with its functional and operational limits.

[0035] After sundown, the smart control system of the smart brick 1 powers the LEDs 80 automatically with colors and the operation mode programmed by the user. By means of smart management, the lighting/illumination power is proportional to the charge harvested/obtained during the day.

[0036] All operational information and functioning possibilities about the solar brick 1 are made available to the user by the means of the NFC interface circuit 58 located in the NFC sensitive area 55 and the firmware. The NFC interface circuit 58 located in the NFC sensitive area 55 and the firmware enables the user through the mobile or specific device to obtain current information about the operational and control conditions of the solar brick 1 which can be read and to program the operation mode.

[0037] Different embodiments of the solar brick 1 may comprise one or more photovoltaic cells, one or more rechargeable batteries, but the electronic circuitry of the photovoltaic cells, microcontroller, NFC interface circuit and accelerometer may or may not be the same for all embodiments. The firmware may also be adapted for specific operating conditions or configuration setups.

[0038] The main purpose and advantage of the solar brick 1 and its smart control system of the present invention is to be able to use the solar brick 1 to highlight pedestrian walkways, safety overpass lanes, architectural contours, inter alia, beyond its conventional uses such as in driveways, parking lots, pool decks, walkways and patios.

[0039] An NFC interface-enabled communications method for a solar brick is also provided and sought to be protected comprising: determining status or function and operating programming of a solar brick 1 by means of a microcontroller 50 including firmware and an NFC interface circuit 58 located in an NFC sensitive area 55, the microcontroller 50 that is coupled to an accelerometer 60 or a temperature sensor 90; feeding sensing, movement or temperature data obtained from the accelerometer 60 or temperature sensor 90 to the microcontroller 50; and setting or adjusting one or more technical functional and operating parameters through a mobile or specific device of one or more RGB-type LEDs 80 that are coupled to a LED driver 70, the LED driver 70 also coupled to the microcontroller 50.

[0040] With all of the advantages and novelties outlined and advanced above in the solar brick 1, its smart control system and NFC interface-enabled communications method of the present invention, architects may enjoy great flexibility in developing architectural projects which can greatly change the luminous appearance of the projects in accordance with diverse and different client needs.
