Custom designed exterior Down Lights as part of a Building Facade Upgrade
S2 was approached by a local building owner to create a vibrant, dynamic, and cost effective series of LED down lights that would be installed as part of a building upgrade facade renovation. Several LED products were considered, but all were static single color (white) typically used for general lighting. LED Fixtures that were more interesting were very expensive, but also were designed to be "added on" to existing roof lines and so lacked the aesthetic appeal of an integrated solution. S2's solution was a custom designed recessed RGBW high power LED fixture with specialty optics allowing the fixture to be used for both down-lighting, but also to enhance some of the building's architectual details. The resulting fixture created downward wall wash along with projecting a 4m diameter light circle on the sidewalk (10 m below the fixture) surrounding the building. Fixtures are all controlled by one of S2's lighting controllers allowing the customer to schedule fixture operation, adjust light colors, or select one of several different animated lighting affects.
- Custom designed fixture included a micro-controller based 4-channel LED driver with fixture control/communication being the Industry standard DMX512 interface.
- State of the art and very high efficiency RGBW (Red, Green Blue, and optically pure White) LEDs were used in each of the twenty-eight (28) light fixtures which were spaced approximately 2m apart.
- Fixture LED output was projected through specialty optics creating both an architecturally pleasing wall wash and a projected "light circle" 10m below.
- To minimize site installation efforts, each of the fixtures had spring loaded retention clips and so a simple drilled hole was all that was needed to fit the fixture.
- Fixtures were Class 2 Low Voltage powered using a Power-over-Ethernet (PoE) derivative solution. This made wiring very easy, efficient, and inexpensive, as off the shelf pre-made Ethernet cables could be used to interconnect the fixtures.
- Fixtures were controlled by one of S2' web based lighting controllers that included DMX512 support, an astrological clock (auto calculation of daily sunrise/sunset times), daily schedules, user adjustable colors, dim levels, and a number of lighting animation sequences. This controller was connected to the customer's LAN allowing the customer or their staff to make lighting control changes as desired.
- The average total power consumption was 56W ... This included all 28 fixtures, controller, with maximum light level output and operating one of the several embedded lighting animations. Please refer to the pictures above and note how much light is projected on the surface surround the building. This is in complete contrast to the off-the-shelf static single color LED fixture which consumed 9W each.
- Total fixture and controller cost was less expensive than static single color off the shelf fixtures, but with more features, functionality, colors, and with superior energy efficiency:
