摘要： A light emitting device includes a light emitting diode (LED), a concentrator element, such as a compound parabolic concentrator, and a wavelength converting material, such as a phosphor. The concentrator element receives light from the LED and emits the light from an exit surface, which is smaller than the entrance surface. The wavelength converting material is, e.g., disposed over the exit surface. The radiance of the light emitting diode is preserved or increased despite the isotropic re-emitted light by the wavelength converting material. In one embodiment, the polarized light from a polarized LED is provided to a polarized optical system, such as a microdisplay. In another embodiment, the orthogonally polarized light from two polarized LEDs is combined, e.g., via a polarizing beamsplitter, and is provided to non-polarized optical system, such as a microdisplay. If desired, a concentrator element may be disposed between the beamsplitter and the microdisplay.

摘要： An illumination device uses a wavelength converting element, such as a phosphor layer, that is physically separated from a light source, such as one or more light emitting diodes, a Xenon lamp or a Mercury lamp. The wavelength converting element is optically separated from the light source, so that the converted light emitted by the wavelength converting element is prevented from being incident on the light source. Accordingly, the temperature limitations of the wavelength converting element are removed, thereby permitting the light source to be driven with an increased current to produce a higher radiance. Moreover, by optically separating the wavelength converting element from the light source, the conversion and recycling efficiency of the device is improved, which also increases radiance.

摘要： A semiconductor structure includes a light emitting region disposed between an n-type region and a p-type region. A wavelength converting material configured to absorb a portion of the first light emitted by the light emitting region and emit second light is disposed in a path of the first light. A filter is disposed in a path of the first and second light. In some embodiments, the filter absorbs or reflects a fraction of first light at an intensity greater than a predetermined intensity. In some embodiments, the filter absorbs or reflects a portion of the second light. In some embodiments, a quantity of filter material is disposed in the path of the first and second light, then the CCT of the first and second light passing through the filter is detected. Filter material may be removed to correct the detected CCT to a predetermined CCT.

摘要： The invention relates to a color-tunable illumination system (10), to a lamp and to a luminaire. The color-tunable illumination system comprises a light source (20) emitting light of a first predefined color (B), and comprises a luminescent material (30) for converting light of the first predefined color into light of a second predefined color (A). The color-tunable illumination system further comprises shielding means (40, 42) arranged for preventing at least part of the light emitted by the light source to impinge on the luminescent material. The light source, the luminescent material and/or the shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color. In the second situation the color-tunable illumination system is arranged for shielding less of the luminescent material to the light of the first predefined color emitted by the light source compared to the first situation. The effect of the measures according to the invention is that the shielding means, luminescent material and/or the light source determine an amount of light of the second predefined color emitted by the color-tunable illumination system which determines a color of the color-tunable illumination system.

摘要： For mixing different light colors from different LEDs or energized phosphors, an elongated mixing tunnel is used having a reflective inner surface. LEDs of different colors are optically coupled along the length of the mixing tunnel and at a first end of the tunnel. Light coupled along the length of the tunnel is reflected by an angled dichroic mirror that selectively reflects the incoming color light towards a single output port of the mixing tunnel. The dichroic mirror passes all other colors of light being transmitted towards the output port of the tunnel. Two, three, or more colors of LEDs can be used. Efficient and compact ways to energize phosphors are also described. Other optical techniques are also described.

摘要： A compact illumination system that is suitable for, e.g., projection systems, includes a plurality of light emitting diodes that are aligned along the same axis. The illumination system includes mirrors and a filter system for combining the light emitted by the different light emitting diodes. The light emitting diodes may be mounted within the same plane, e.g., on the same heatsink, which simplifies assembly and alignment of the system. Moreover, a collimator system with integrally formed refractive and/or reflective collimators, may be used. The use of an integrally formed collimator system advantageously reduces the number of piece parts and simplifies assembly.
