Embodiment Construction

[0055] Hybrid solutions are implemented in many lighting devices comprising LEDs of different colors in order to provide a mixture of colors and improved light output characteristics. When implementing a hybrid solution, many light fixtures employ multiple large mixing cavities and / or provide illumination from only a single planar light exit opening. Such a configuration may result in an undesirably large hybrid solution and / or a hybrid solution of limited utility. Accordingly, Applicants have recognized a need for an LED-based luminaire that can provide satisfactory mixing of light output from its multiple LEDs and that can optionally overcome existing mixing solutions. One or more deficiencies in the program.

[0056] The LED-based luminaire may include hybrid optics surrounding a plurality of LEDs. The LEDs can optionally be of different colours. The mixing optics include multiple internal reflective surfaces for mixing the light output of the LEDs. The hybrid optic als...

Abstract

Disclosed are LED-based luminaires (10, 110, 210, 310, 410, 510, 610, 710). The optics may include multiple internal reflective surfaces for mixing the light output of the LEDs and also include a transmissive diffuser (30, 130, 230, 330, 430, 530, 630a / b, 730a / b) , through which the light output of the internally reflected LED exits the LED-based luminaire.

Description

technical field [0001] The present invention is generally directed to LED-based luminaires. More specifically, various inventive methods and apparatus disclosed herein relate to LED-based luminaires with hybrid optics surrounding multiple LEDs. Background technique [0002] Digital lighting technology, ie lighting based on semiconductor light sources such as light emitting diodes (LEDs), presents 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 many others. Recent advances in LED technology have provided efficient and robust full-spectrum light emitting sources that enable a variety of lighting effects in many applications. Some of the devices incorporating these sources feature light emitting modules that include one or more LEDs capable of producing different colors (e.g., red, green, and blue) and outputs fo...
