We've just learned of a significant USA design win for the
patented Sol Chip Pak™ (SCP-R2801) Power Modules to control LED lighting fixtures. https://www.saelig.com/product/sol-chip-pak.htm
They offer 24/7 non-stop
functionality by combining state-of-the-art solar cells, a rechargeable
battery, and advanced power management circuitry. These power modules include
all the components that are required to harvest energy from ambient light,
charge a built-in rechargeable battery, and deliver a stable voltage to a load.
Sol Chip’s patented technology integrates solar energy conversion with very
large scale integration (VLSI) techniques to produce unique ambient light
harvesting devices that can even extract energy from office lighting to provide
constant power. These versatile boards, based on Sol Chip’s unique Saturn
cells, provide power even in office light conditions.
The
output voltage of these "everlasting solar batteries” is regulated to
3.6V, but other voltages are available by request to suit alternate
applications. Versions are available with 1, 2, 3, or 6 Saturn solar cells
depending on the power needs. The 6-cell version provides an average output
current of up to 750mA from the integrated solar cells, with up to 1.5A peak
current. The capacity of the 3.6V onboard rechargeable batteries in the series
is 190 - 1100mAh.
The SCP
series of boards allow product designers to build fit-and-forget light-powered
products that can recharge themselves. Existing products can be modified by
simply disconnecting a device’s traditional batteries and plugging in an SCP to
create a self-powered, no maintenance device. All that is needed is a small
window to allow light to reach the board - it does not even need to be pointed
to the sky. Operable in sunlight and indoor environments, it removes the need
for a battery power source in low power applications, removing maintenance
headaches and hazardous battery waste issues.
Incorporating
an SCP module into mobile designs is perfect for hard-to-reach locations, and
eradicates the significant costs and time associated with installing and
maintaining wiring to connect deployed sensors, and thus reduces the cost of
system ownership. The SCP series is ideal for designing in to remote sensors
and monitoring systems that are used in diverse applications such as:
agriculture, farming, drip-irrigation systems, weather testing, as well as
security, IoT, wireless sensor networks, wearable electronics, etc. Other
applications include smart city solutions for everything from parking to
security and utility meters, data loggers, GPS emergency locators, animal
tracking devices, GPS asset/container tracking, GPS vehicle tracking,
environmental measurement and radio frequency identification (RFID) devices,
etc.
The design win incorporates the solar chips on to the customer's own PCB, thus saving significant costs.
