摘要： A total-internal-reflection (TIR) lens for color mixing includes a body member having an outer surface and an interior open channel extending longitudinally through the body member. The body member and the interior open channel are substantially symmetric with respect to an optical axis, and the outer surface is shaped to provide total internal reflection. The body member has a first end surface region at a first end of the open channel for accommodating a light source and a second end surface region opposite the first end region. The second end surface region includes a plurality of refractive surface regions positioned around the second end region of the open channel. The lens is configured to provide projected light substantially centered with respect to the optical axis when the light source is positioned off the optical axis. In a specific embodiment, a lighting apparatus for providing centered white light includes such a lens and a plurality of light sources.

摘要： A metal plate on a multi-die LED emitter substrate or a metal plate on a metal-core printed circuit board (MCPCB) that attaches to the emitter substrate (or both plates) can be fabricated with a number of generally radial grooves, at least some of which extend to the peripheral edge of the plate. These grooves can provide channels that allow air to escape during solder-bonding processes, reducing the size and/or total area of solder voids and thereby improving thermal transfer between the emitter and the MCPCB.

摘要： The color of an LED-based lamp can be tuned to a desired color or color temperature. The lamp can include two or more independently addressable groups of LEDs associated with different colors or color temperatures and a total-internal-reflection (TIR) color-mixing lens to produce light of a uniform color by mixing the light from the different groups of LEDs. The color of the output light is tuned by controllably dividing an input current among the groups of LEDs. Tuning can be performed once, e.g., during manufacture, and the lamp does not require active feedback components for maintaining color temperature.
