Embodiment Construction

[0035] LED-based lighting fixtures and arrays have been implemented that enable individual control of groups of light sources within such fixtures and arrays. While such lighting fixtures enable individualized control of groups of light sources, the sensors used in such individualized control have one or more disadvantages. For example, sensors may be bulky, consume too much power, be overly sensitive to heat and / or overly sensitive to noise, limiting options for implementation in lighting units. Accordingly, Applicants have recognized and recognized the need in the art to provide a lighting unit with radar for presence detection which optionally overcomes one or more of the disadvantages of existing lighting units.

[0036] More generally, applicants have recognized and realized that it would be beneficial to provide methods and apparatus relating to LED-based lighting units with radar devices for presence detection.

[0037] In view of the foregoing, various inventive metho...

Abstract

Methods and apparatus relating to LED based lighting units (10; 110; 210; 310; 410) with radar for presence detection. The radar circuit (140; 240; 340A; 340B; 440) may be electrically coupled to conductive wiring (25; 125; 225; 325; 425). In some embodiments, an antenna coupled to the radar circuitry may be formed from conductive wiring, and optionally at least partially isolated from any current flowing through the LED.

Description

technical field [0001] The present invention is generally directed to lighting units configured for presence detection. More particularly, various inventive methods and apparatus disclosed herein relate to LED-based lighting units employing radar devices for presence detection. Background technique [0002] Digital lighting technology, ie lighting based on semiconductor light sources such as light emitting diodes (LEDs), offers a viable alternative to traditional fluorescent, HID and incandescent lamps. Functional advantages and benefits of LEDs include high energy conversion and optical efficiency, durability, lower operating costs, and the like. Recent advances in LED technology have provided efficient and robust full-spectrum lighting sources that enable a variety of lighting effects in many applications. Some fixtures embodying these sources feature lighting modules comprising one or more LEDs capable of producing different colors, such as red, green, and blue, and out...
