Philips' Light at the Museum Pilot Study

The Dutch National Museum for Science and Medicine was home to Philips' landmark pilot study for connected lighting mobile apps. Findings from the study indicated that 7 out of 10 museum visitors would like to receive location relevant information via their smartphone.

Philips, the global leader in lighting, hopes this innovative mobile app for connected lighting will provide a template for use in museums, hospitals and supermarkets in the not so distant future. 

The exhibition is part of a pilot project for Philips' LED based connected lighting systems for indoor positioning. The connected lighting systems use Visual Light Communication (VLC) technology. The exhibitions luminaires are placed in a positioning grid, they are individually identifiable and communicate with the camera's sensors in smartphones and tablets. Each light fixture in the grid communicates by blinking at high frequencies undetectable to the human eye, information relevant to the patrons location within the exhibition is transmitted through these fast pulses. VLC transmits data one way only meaning users personal data cannot be accessed by the connected lighting app. 

Upon arrival at the museum, visitors were given a tablet with a pre-installed app, the app contains a variety of multi-media content relevant to various locations within the exhibition. As the visitor moves around the exhibition, the individual light fixtures act as positioning beacons transmitting their location to the tablets camera sensor which trigger the apps content at various locations.
Visitors completed a short survey after their museum tour, the findings indicate that;
67% of visitors liked the fact that the tablet automatically provided additional relevant information at various information points

63% of visitors said that the tablet made the visit to the exhibition more enjoyable and interesting
50% of visitors under 50 years old said they would visit museums and exhibitions more often if there were tablets available to provide additional information or to guide them around a special route

Dirk Van Drift, Director of the Boerhaave Museum said: “We now know that offering a location aware and interactive experience encourages people to visit our museum more often. What is also really exciting and innovative is that we were able to achieve this by using energy efficient lighting, giving us a double advantage.”

The “smartphone generation” (those under 50) said they were open to trying connected lighting mobile applications in a number of settings. Almost 50% of all visitors claimed they would like to receive location-based information and use way finding services offered via the app in hospitals, shopping centres and supermarkets.

Jella Segers, from Philips Lighting said: “The survey findings show that we need to think of lighting differently. Lighting has gone beyond mere illumination. We can now deliver great quality and highly energy-efficient LED lighting that acts as a positioning grid to deliver targeted information, enriching people’s experiences of the places they visit, whether it’s a museum, supermarket, airport terminal or any large public indoor space.”

New to The LED Specialist: Danlers RESLOADE

This latest addition to our stock is a resistive load designed to eliminate lamp instability and flicker which often occurs when non-resistive loads such as LED lamps are dimmed. This product is also compatible with compact fluorescent lamps and dimmable transformers which are prone to the same instability as LED lamps.

The RESLOADE is designed to be used with Danlers Grid trailing edge dimmers (DQDGD) when dimming LED lamps and any other use of this product will invalidate its warrantee. The RESLOADE must be connected to Earth. For direct mains dimmable lamps the RESLOADE is connected at a suitable light fitting, in parallel across the load, between the dimmed variable live and neutral. For mains dimmable transformers the RESLOADE is connected across the primary (variable mains input) side of the transformer.


The RESLOADE is designed to be placed in the ceiling void and can be passed through a 63mm diameter cut-out, the typical size for down lighters. The RESLOADE has an effective load of 10w and an operating temperature of approximately 40°c above ambient. It should be installed where air flow is not restricted. It should not be covered by insulating materials or positioned near any heat sources or heat sensitive objects.
