ELMOS Introduces New Lighting Concepts with Gesture and Motion Control at Light+Building 2012
This is how the lighting concepts of the future will look like: Barely awake, you move your hand in the direction of the lamp. Immediately it lights up dimly. If you move closer to the lamp, its light becomes brighter increasingly. Pulling back your hand will make the light go out again at once. But letting the hand linger for a short time will switch on the light permanently while fixing the desired brightness at the same time. All this is made possible even today by the HALIOS® sensor systems of the company Mechaless, detecting hand gestures most precisely at minimum power consumption. Touchless, without having to search for the switch in the dark.
The patented HALIOS® principle (High Ambient Light Independent Optical System) is the only method worldwide that utilizes proper optical compensation. This facilitates an extensive neutralization of parasitic physical effects in the photodiode, starting with the ambient light effect up to peerless temperature stability, far beyond the capabilities of the separate components. The system’s response time can be configured quickly and simply via software. The actual measurement consists of a power saving pulse packet which takes only up to 250 µs per channel. The received signal is then made available for customer specific analysis in the integrated 16-bit microcontroller.
The low power consumption results from the robustness of the measurement principle. Short measurement time – protracted integration or filtering of the values is unnecessary here – in connection with the integrated 16-bit microcontroller allows the context specific optimization of the measurement frequency and reduces the average power consumption to the application specific minimum.
The semiconductors with HALIOS® technology, E909.05 and E909.06, provide great flexibility for meeting even the requirements of more complex applications. In addition to the four independent output drivers, the ELMOS E909.06 component in a compact QFN 5x5 32 Ld package offers a specially designed differential receive path. Connectable here are one or two photodiodes, or one photodiode fully symmetrically. Eight digital inputs/outputs as well as one I²C and one SPI or LIN (UART) interface are available.

You can find a demonstrator for this innovative lighting control concept at the booth: “LED Light for you” powered by Osram, at Light+Building 2012 in Frankfurt/Main (April 15-20).
