1 Latest trends and technologies for High-End Retail Lighting Dr. Dieter Groß, Business Development Manager Lighting Contact in the Netherlands: Martijn Knop, +31 (346)

2 Introduction Real shopping experience Customers pay up to 50% more in traditional retail versus online Welcome athmosphere: - Smell & Taste - Touching - Hearing - Sight Lighting Optical presentation of goods must be excellent, appealing as sign of quality Lighting High End Retail Customer insights & facility management Smart Lighting Luminaire as sensor hub Individual personal treatment Smart Lighting Loyalty programs, proximity marteting Additional information on goods, promotions, indoor location Smart Lighting Indoor navigation, proximity marteting 2

3 Outline Layers of Light in Retail Shops (Outdoor apperance, Ambient Lighting, Valance Lighting, Shelf Lighting, Accent & Display Lighting, Decorative Lighting) Smart Lighting / Luminaire as a Hub (Sensors options, proximity sensors, Indoor navigation) Perception of Light and Color (Brightness, Color, Mac Adams elipses, speciality colors) 3

4 Layers of Light in Retail Shops

5 Layers of Light: 1. Façade & Shop Window Lighting - Tempt passers-by to enter the shop by: - effectively-lit facade - beautifully decorated and illuminated shop window - dynamic control system (by changing focus periodically or fading singular items in and out) - good lighting products appear promising shop is inviting Suitable LEDs: Various size COBs Suitable optics: Ledil Carmen Ledil Ronda 5

6 Layers of Light: 2. General/Ambient Lighting (spots) - Main light source for a store. - Diffuse background lighting, NO GLARE - Provide enough light to find the way - Indirect light rooms gain in height. - Provides clients comfort, no glare e.g. LEDils s dark lighting concept: - Black reflectors - Light source not visible, only effect of light - Higher intensities and less spill light compared to metallized reflectors. Suitable LEDs: HP LEDs 3030, 3535 with high CRI Various COBs Suitable optics: Ledil Tina Ledil Florentina 2x2 holders Reliability & Trust Entrepreneurship & Innovation Empowerment & Execution Ledil Established Carmen-M since

7 - Lights vertical surfaces and walls - Typically behind the merchandise area Typically: - Wall washing (one source illuminates the whole wall) - Cove lighting (indirect lighting built into ledges, recesses or valences in a ceiling) sense of space Layers of Light: 3. Perimeter/Valance Lighting help for orientation through the store. Suitable LEDs: MP LEDs (typ. 5630) with high CRI Suitable optics: Ledil Zenia Ledil Ronda-WAS Various COBs 7

8 Layers of Light: 4. Shelf & Case Lighting - lighting very close to products. - remarkable influence on the depiction of the merchandise by color parameters - Special colors available: - Briliant colors at 3000 K for bags, shoes,.. - Bread, meat, vegetables, fish LEDs available, too - E.g. Louis Vuitton: exclusive atmosphere - atmospheric warm-toned lighting - halo-lit shelf systems secure, pampered feeling Suitable LEDs: MP LEDs (typ. 5630) with high CRI Suitable optics: Ledil Zenia 8

9 Layers of Light: 5. Accent and Display Lighting (track) - Spots on tracks to highlight merchandise - typically flexibly positioning on tracks - dynamics appearance of shop (by changing focus periodically or fading singular items in and out) - Sparkling effect of jewels with high center beam candela powers (CBCP) in contrast to the dim ambient light (illumination levels of lx) small LES/high-density COBs recommended Suitable optics: Suitable LEDs: Ledil Carmen-S Vivid type COBs Ledil Ronda Small LES/high Ledil Molly density types Ledil Winnie Tunable white: Gabriella 9

10 Layers of Light: 6. Decorative Lighting - E.g. chandeliers, pendants or other luminaires - Provide visual interest or sparkle - To draw guests into a retail space - Also attractive markers for e.g. checkout stations or seating areas Suitable LEDs: Various size COBs Suitable optics: Ledil Zorya Ledil Zorya-Mini 10

11 Smart lighting / luminaire as a hub

12 Luminaire as Hub for Sensors and as Infrastructure everywhere electrical power good position for sensors By turning every light node into a data access point lighting provides the most granular network of sensors and actuators for Smart Buildings at comparably low costs. 12

13 Luminaire as a Sensor Hub Temperature & humidity sensors Pressure sensing (for e.g. window opening) Ambient light sensors Gas sensing (CO 2, VOCs ) Motion detection (PIR, Radar, Noise,..) Presence detection (Radar, ultrasonic, ToF (Time-of- Flight sensors)) for infrastructure: LiFi / visible light communication (VLC) Indoor positioning (via BLE-Beacons) Comparison of parameters Radar PIR presence detection ++ + velocity information distance information optional -- typ. detection range (person) upto 50m typ. 12m Independency on weather ++ + power consumption O ++ Detection of radial movement ++ - Detection of tangential movement - ++ hidden installation cost

14 Spectral Tuning IoT Smart Lighting Manager Features: Integrated sensing with autonomous luminaire management (Daylight harvesting) CCT-tunability corresponding to CIE 1931 color space Extensible capabilities to support daylight harvesting Configurable scene-based operation options IoT sensor hub capabilities via I2C expansion bus and networking (e.g. for Bluetooth) for smart building and HCL 14

15 SAMSUNG SMART LIGHTING PLATFORM Smart lighting including sensors, connectivity and color tuning 2-channel Driver (DALI DT 8, 0-10V) Wireless control module (BLE 4.2 Mesh, ZigBee) Sensors & bridge App & cloud server for smartphone Wired (DALI DT 8, 0-10V) Wireless control module (BLE 4.2 Mesh, ZigBee) Daylight / Presence / Motion / Temperature / Humidity (BLE connectivity) 15

18 Perception of Light and Color

19 Perception of Light Brightness perception: e.g. pupil size changes high variation of light input possible logarithmic perception for brightness 10% brightness difference is hardly seen Color perception: color sensors (cones) in retina are responsible for color vision (RGB!) Allmost linear perception of color differences Receptor cells (cones) in the retina Cones on retina for color vision 19

20 Mac Adams Ellipses in General CIE XYZ Color Space (from 1931) Most commonly used Limitation: perceptable color difference is not equidistant / linear Solution: - MacAdam ellipses: color difference within one step ellipses hardly perseptible by most peoble. (Study based on only one observer) - CIE-UCS (Uniform Color Scale) (1976) y 10 step MacAdam ellipses in CIE XYZ color space for visualisation.

23 Special LED colors: Vivid spectrum more applealing colors: Vivid spectrum pursues high contrast for Showcases 23

24 Special LED colors: Fashion, Meat, Vegetable 24

25 Take Away messages

26 Take away message Light is THE INFLUENCER in retail for athmosphere and presentation Glare must be avoided Accents for good presentation Luminare as sensor hub provides existing infrastructure electricity prominent position Perception of Light Brightness non linear (10% brightness inhomogenety barely visible) color perception almost linear, little influences are visible special spectra LEDs available as best compromise between color rendering and efficiency 26
