A light emitting device, comprises at least: a light emitting element; a wavelength conversion member for converting the wavelength of light from the light emitting element; a bendable light guide member for guiding light from the light emitting element to the wavelength conversion member; and a heat conduction member that is thermally connected to the wavelength conversion member.

A fluorescence concentrator system that provides for high brightness light source. The system can include a host doped with fluorescent material, which is optically pumped by an adjacent illumination source. The fluorescence concentrator captures a portion of the isotropically emitted fluorescent light and guides it to an output surface. The fluorescent energy emerging the output surface provides a high brightness light source suitable for a number of applications. For example, the fluorescence concentrator system can be used as the light source in a medical apparatus suitable for various aesthetic procedures. Further aspects of the fluorescent concentrator system can include providing for controlling the illumination source to output pumping energy suitable for high energy applications.

A light-emitting diode (“LED”) device has an LED chip attached to a substrate. The terminals of the LED chip are electrically coupled to leads of the LED device. Elastomeric encapsulant within a receptacle of the LED device surrounds the LED chip. A second encapsulant is disposed within an aperture of the receptacle on the elastomeric encapsulant.

A lighting device having a light emitting diode (LED). The device includes a metal substrate having a surface. A dielectric coating layer is superimposed on the surface of the metal substrate. A light emitting diode (LED) is supported on the dielectric coating layer. The metal substrate serves as a heat sink for the heat emitted by LED during operation.

The invention provides a fluorescent powder lamella, a fluorescent powder color wheel, and a light source using the fluorescent powder lamella. The fluorescent powder color wheel comprises a substrate and the fluorescent powder lamella, wherein the fluorescent powder lamella comprises a lamella which is formed by bonding fluorescent powder particles with an organic or inorganic binder; the granularity of the fluorescent powder D50 is greater than or equal to 20 mu m; the fluorescent powder lamella covers at least one part of the one side surface or forms at least one part of the substrate, and can be excited and converted into excited light of at least one color. Compared with the prior art, the fluorescent powder lamella, the fluorescent powder color wheel, and the light source using the fluorescent powder lamella provided by the invention adopt the fluorescent powder of which the granularity D50 is greater than or equal to 20 mu m; and high efficiency of the fluorescent powder lamella can still be maintained in high exciting light power density.

In one embodiment, a light emitting panel includes a base panel and a plurality of light emitting elements mounted to the base panel. Each of the light emitting elements produces an illumination pattern having a region of substantially uniform intensity that extends over a radiation angle of at least about 60°. One or more light conditioners are positioned adjacent the base panel to receive and condition light produced by the light emitting elements.
