Getting started with smart home lighting based on HVLED815PF
and SPSGRF
Introduction
The STEVAL-ILL082V1 is based on the HVLED815PF off-line LED driver. It consists of a LED driver
board with a connectivity module and the STM32L0 microcontroller, which manages wireless
communication and LED brightness control. The microcontroller and connectivity module are supplied
by the LED driver through an auxiliary winding.
STEVAL-ILL082V1 can be operated in standalone mode through the communication with the bundled
STEVAL-ILL082V1_Remote controller based on SP1ML to help to reduce development and certification
time.
The board can also be rendered visible to cloud applications with the addition of a wireless bridge.

1.1 Smart home lighting architecture
The architecture behind this smart home lighting system involves an LED driver
(HVLED815PF) to supply and monitor the LED load, an STM32L05x microcontroller to
manage the board, a low power sub-GHz module based on the SPIRIT1 RF transceiver
(SPSGRF) for external communication and a remote application running on an Android®
mobile device to display status information and generate remote commands.
Cloud-based IoT functionality is supported with the introduction of a separate ST wireless
bridge (STEVAL-IDI004V2) or through a remote controller (SP1ML).

The bottom side of the STEVAL-ILL082V1 board is figured below.
Figure 5: STEVAL-ILL082V1 key components (bottom view)
Key bottom side components include:
•HVLED815PF: offline constant current LED driver with primary-sensing, integrated
MOSFET, high power factor, low THD and ability to supply 15 W controlled power.
•SPSGRF: low power sub-GHz module based on SPIRIT1 RF transceiver and BALUN.
It enables wireless connectivity requiring no RF experience or expertise for integration.
It has a programmable radio which supports different modulation schemes (e.g. FSK,
GFSK, MSK, GMSK, OOK and ASK). The output power can vary up to 11.6 dBm and
the receiver sensitivity is -118 dBm. Four GPIOs are available and can be
programmed for 32 different input/output functions. SPSGRF is FCC, IC and CE
certified. It is available in two different carrier frequency versions to cater 868 MHz
SRD and 915 MHz ISM bands.
•STM32L05x: ultra-low power 32-bit RISC microcontroller based on the ARM®Cortex®-
M0+ core, featuring an advanced APB bus, ADC, timer, I²C, SPI and USART.
•STTH1L06 and STTH2L06: ultra-fast high voltage rectifiers, with low reverse recovery
current and low thermal resistance.
•LDL212: a 3.3 V low dropout regulator (LDO) to supply the MCU and SPSGRF.
•SW1: reset switch for the microcontroller and connectivity module.

Use SP1ML (STEVAL-ILL082V1_Remote) to control the LED brightness from 2.5%
to 100% or to switch LEDs on or off.
SW1 decreases output current and switches LEDs off.
SW2 increases output current and switches LEDs on.

3.2 IEC61000-3-2 class C harmonic measurement
The STEVAL-ILL082V1 is IEC61000-3-2 compliant. The harmonic current is measured
from the 2nd to the 39th harmonic order as required by IEC61000-3-2 class C for lighting
equipment. The measured value at 230 VAC is well behind the specified harmonic limits.
Figure 14: STEVAL-ILL082V1: full load condition
3.3 LED dimming versus output power and LED current
The LED dimming is implemented in 5 steps: 2.5, 20, 40, 60 and 80% of the LED power
output. It is linear for the entire EU line voltage range and almost independent from line
voltage variations.
Figure 15: STEVAL-ILL082V1: LED dimming linearity
3.4 Standby power consumption
The STEVAL-ILL082V1 evaluation board standby power consumption is between 0.4 and
0.6 W for the entire line voltage variation.
At the lowest dimming condition, the power consumption is less than standby thanks to the
fact that HVLED815 PF IC is working in high voltage startup mode to generate 3.3 V
housekeeping power supply.
