Abstract: A lighting device comprises multiple modules each having an array of LED chip connection pads. Interconnections between the pads provide groups of connection pads, each group comprising a parallel set of connection pads, and the groups being in series with each other. An optical unit is provided for shaping the light output from LED chips mounted on the pads. The groups are defined to minimize an overall spacing of the pads within the groups (in combination) to provide a best possible color mixing for the LEDs mounted on the connection pads.

Abstract: According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

Abstract: An aircraft reading light with a color-tunable reading light output includes: a white light source for emitting white light; a colored light source for emitting colored light; and an optical element, which is arranged for directing colored light that is emitted by the colored light source onto the white light source for being diffusely reflected at the white light source. The colored light source is controllable independently from the white light source.

Abstract: Disclosed is a novel lens for an LED light source, and a projection lamp with the same. The lens includes a reflection portion and a divergence portion. A light source is refracted by the reflection portion and then projected to the divergence portion, by which a light beam is then diverged out. The divergence portion has a flat surface side and a concave surface side, and the reflection portion is arranged on the flat surface side. The utility model has the following beneficial effects: the structure is exquisite, by using a new structural design for a focus lens, the light beam of the LED light source is reflected and refracted multiple times in the lens and then diverged, which solves the problem of large area of the LED light source, and at the same time, after being re-focused, the light beam is suitable for forming higher-brightness white light.
