    摘要: An illumination device (200-c;200-d) includes a light source (210-c;210-d) configured to emit, during operation, light with a prevalent direction of propagation different from a direction of an optical axis (102-c) of the illumination device; and an optical coupler (220-c;220-d) including a transparent material, the optical coupler having an input aperture, an exit aperture (225-c,225-d) and a first side surface (224-c;224-d) and a second side surface (226-c;226-d) arranged between the input aperture and the exit aperture (225-c;225-d), the exit aperture being centered on the optical axis of the illumination device. The optical coupler (220-c;220-d) receives the emitted light through the input aperture from the light source. Further, the first side surface and the second side surface redirect the received light via total internal reflection (TIR) to the exit aperture. Additionally, the redirected light is issued through the exit aperture.

    摘要: A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light emitting diodes) are disclosed. In general, the devices include a scattering element in combination with an extractor element. The scattering element, which may include elastic and/or inelastic scattering centers, is spaced apart from the light source element. Opposite sides of the scattering element have asymmetric optical interfaces, there being a larger refractive index mismatch at the interface facing the light emitting element than the interface between the scattering element and the extractor element. Such a structure favors forward scattering of light from the scattering element. In other words, the system favors scattering out of the scattering element into the extractor element over backscattering light towards the light source element. The extractor element, in turn, is sized and shaped to reduce reflection of light exiting the light-emitting device at the devices interface with the ambient environment.

    摘要: In a single lighting device including a large number of light-emitting elements (LEEs), the LEEs are divided into separately powered groups, and different combinations of the groups are fully energized to achieve the desired overall brightness. In some embodiments, the number of LEEs in each group has a binary relationship to the other groups. The resolution of the dimming is the brightness of the smallest group. In one example of five binary weighted groups of LEEs, 32 brightness levels can be achieved while the LEEs in the energized groups are fully ON. Thus, since there is no high frequency switching, there is substantially no power dissipation by the dimming control system, and there is limited noise or EMI created. The dimming control can be easily implemented with a logic circuit controlling a transistor switch for each group.

    摘要: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED dies (56) have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a bottom substrate (292). Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate (300) is then formed over the bottom substrate (292). Various ways to operatively interconnect the LEDs are described along with many embodiments. According to some embodiments, the top substrate contains a conductor pattern that connects to LED electrodes and conductors on the bottom substrate. In another embodiment, a conductor layer is formed on the outer surface of the top substrate and makes contact with the LED electrodes and conductors on the bottom substrate via openings formed in the top substrate.
