Problems solved by technology

Additionally, lighting fixtures using LEDs are expensive due to the necessary color control electronics and / or sensors to maintain the color point of the light source, or the need to use those that meet the color and / or flux requirements of the application production of LEDs, which are less selective

Embodiment Construction

[0035] Reference will now be made in detail to background examples and some embodiments of the invention, examples of which are depicted in the accompanying drawings.

[0036] figure 1 , 2 3 and 3 illustrate three exemplary luminaires, all designated 150 . figure 1 The illustrated luminaire includes a lighting module 100 having a rectangular form factor. figure 2 The illustrated luminaire includes a lighting module 100 having a circular form factor. image 3 The luminaire shown comprises a lighting module 100 integrated in a retrofit lamp arrangement. These examples are for illustration purposes. Examples of lighting modules having substantially polygonal and elliptical shapes are also conceivable. The illuminator 150 includes the lighting module 100 , the reflector 125 and the lamp 120 . As shown, light fixture 120 includes heat dissipation capabilities and may therefore sometimes be referred to as heat sink 120 . However, light fixture 120 may include other structura...

Abstract

An illumination module includes a plurality of Light Emitting Diodes (LEDs) (102A-102C). The illumination module includes a reflective mask cover plate (173) disposed over the LEDs. The reflective mask includes a patterned reflective layer (175) with an opening area aligned with the active die area of the LEDs. The reflective mask may be a patterned reflective layer disposed between the plurality of LEDs and a lens element (200), wherein a void in the patterned reflective layer (201) is filled with a material that mechanically and optically couples the plurality of LEDs and the lens element. The illumination module may include a color conversion cavity (160) that envelopes a lens element that may include a dichroic filter (904). The lens element (200) may have different surface profiles (207, 208) over different groups of LEDs.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Application No. 13 / 527,443, filed June 19, 2012, and U.S. Application No. 13 / 527,446, filed June 19, 2012, both of which claim 2011 under 35USC119 US Provisional Application No. 61 / 500,924, filed June 24, 2011, and US Provisional Application No. 61 / 500,924, filed December 5, 2011, all of which are incorporated herein by reference in their entirety. technical field [0003] The described embodiments relate to lighting modules comprising light emitting diodes (LEDs). Background technique [0004] The use of light emitting diodes in general lighting is still limited by limitations in the light output level or light output flux produced by the lighting fixture. Lighting devices using LEDs also typically suffer from poor color quality characterized by color point instability. Color point instability varies over time and varies from part to part. Poor color quality is also characte...
