Abstract: An organic luminous means and an illumination device comprising such a luminous means are specified. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are furthermore specified.

Abstract: Arrangements of solid state light sources for color-mixing, and light sources including the same, are provided. A substrate has and a plurality of different color LED chips coupled thereto. The emitted light is mixed to produce a white light output. The LED chips are arranged on the substrate in a manner that improves color-mixing, for example, by forming LED sets including one or more LED chips of different colors, by skewing the LED chips, and/or by forming a non-rectangular array or a circular array of LED sets and/or chips. The color-mixing LED arrangement may be used in a lamp or other light source together with collimating optics to collimate and further mix the color-mixed light output from the LED arrangement. The color-mixing LED arrangement may be provided as a single package with multiple LED chips or as multiple packages of one or more LED chips.

Abstract: A lamp (10) has a light source (12) comprising a press seal (17). A lamp envelope (18) receives the light source (12), the envelope (18) having a base (22). A clip-receiving aperture (24) is formed in the base (22), and a clip locator surface (26, 52, 54) is formed in the base (22) adjacent the clip-receiving aperture (24). A clip (28) is positioned in the clip-receiving aperture (24) to receive the press seal (17). The clip (28) has a first retainer (32) and a second retainer (33), the first retainer (32) engages the clip locator surface (26, 52, 54), whereby the clip (28) is located within the clip-receiving aperture (24). The second retainer (33) secures the clip (28) to the base (22), and a third retainer (34) secures the press seal (17) of the light source (12) within the clip (28).
