Further intelligence includes the ability to create lighting networks that communicate across distances, from local to remote locations. This allows for the ability to increase aesthetics, energy savings and reduce maintenance with items such as fixed light output and color in large lighting arrays from street lamps to large rooms, monitoring light output and providing real-time operating issues. Additionally, this provides the ability to integrate lighting into other technologies such as security systems or home automation. Aesthetically, lighting control offers the ability to support custom mood lighting by varying brightness, color and color temperature as well. Wired protocols Wireless – transceivers and modules

LED drivers for human centric lighting
Gone are the days of standard overhead fluorescent lights that result in fatigue, eye strain and uncomfortable working environments. Human centric lighting (HCL) is the understanding that there are often discrepancies between natural light and artificial light which can result in a powerful effect on our productivity, mood and can even impact our overall health. Selecting the right LED driver is a key component to creating an effective HCL product design.
Benefits of designing human centric lighting systems
Businesses can benefit by adopting a more human-centric approach to the lighting in offices, factories and other buildings. Improving employee productivity, health, emotional stability and overall comfort can be as simple as incorporating lighting systems that complement the natural cycle of light.
Advancements in LED technologies allow designers to create dynamic lighting systems that match our bodies’ natural circadian rhythm and boost the existing natural light within a space with carefully tuned artificial lights. Designing lighting systems that are geared toward minimizing the discrepancies between natural and artificial light require engineers to have tools that provide a high level of control over several different aspects of light.
Systems that aim to improve the quality of light require high color rendering index (CRI), correlated color temperature (CCT) compensation and the ability to adjust level of light at just the right time.
Characteristics and requirements
To achieve human centric lighting, the solution has to have certain key features:
- Quality of light: The ripple or flicker index of the solution should be low enough to not impact the quality of light produced.
- Color mixing: The ability to mix different color temperature lights to produce light that is close to the person’s mood and/or time of the day.
- Dimmable: Capabilities to dim the intensity of the light according to the mood.
- Wireless connectivity: The ability to be able to change the color and intensity of the light through wireless control.
Microchip has developed a reference design that demonstrates how customers can drive two different temperature color LED strings and how to control the desired color through Bluetooth® communication. This solution combines a buck LED driver (HV9961) with an 8-bit microcontroller (PIC16F15313) which communicate through UART with the Bluetooth module (RN4871) to create an intelligent LED lighting system solution. This demo combines a Bluetooth low energy module which includes a Bluetooth 4.2 baseband controller, on-board Bluetooth stack, digital and analog I/O and RF power amplifier into one solution.Reference Design: HV9961 with Bluetooth® Control
LED Driver
Average-Current mode Constant-Current control
HV9961 is an average current mode control LED driver IC operating in a constant off-time mode. This control IC does not produce a peak-to-average error, and therefore greatly improves accuracy, line and load regulation of the LED current.
