摘要:
Various embodiments for providing removable and pluggable opto-electronic modules for illumination and imaging for endoscopy or borescopy are provided for use with portable display devices. Generally, various medical or industrial devices can include one or more solid state or other compact electro-optic illuminating elements located thereon. Additionally, such opto-electronic modules may include illuminating optics, imaging optics, and/or image capture devices. The illuminating elements may have different wavelengths and can be time-synchronized with an image sensor to illuminate an object for imaging or detecting purpose or other conditioning purpose. The removable opto-electronic modules may be plugged in on the exterior surface of a device, inside the device, deployably coupled to the distal end of the device, or otherwise disposed on the device.

A device is provided with an array of a plurality of phosphor converted light emitting devices (LEDs) that produce broad spectrum light. The phosphor converted LEDs may produce light with different correlated color temperature (CCT) and are covered with an optical element that assists in mixing the light from the LEDs to produce a desired correlated color temperature. The optical element may be bonded to the phosphor converted light emitting devices. The optical element may be a dome mounted over the phosphor converted light emitting devices and filled with an encapsulant.

An illumination device includes a light source, such as one or more light emitting diodes and a wavelength converting element that is mounted on an opaque support structure. The support structure includes an aperture with which the wavelength converting element is aligned so that the converted light is emitted through the aperture. The wavelength converting element may be a rigid structure, such as a luminescent ceramic and the aperture may be a hole through the support structure. The support structure may hold the wavelength converting element so that it is physically separated from the light source, or alternatively, the support structure may place the wavelength converting element in physical contact with the light source.

A semiconductor light emitting device package includes a substrate with a core and a copper layer overlying the core. The light emitting device is connected to the substrate directly or indirectly through a wiring substrate. The core of the substrate may be, for example, ceramic, Al2O3, AlN, alumina, silicon nitride, or a printed circuit board. The copper layer may be bonded to the core by a process such as direct bonding of copper or active metal brazing.

摘要:
A device is provided with at least one light emitting device (LED) die mounted on a submount with an optical element subsequently thermally bonded to the LED die. The LED die is electrically coupled to the submount through contact bumps that have a higher temperature melting point than is used to thermally bond the optical element to the LED die. In one implementation, a single optical element is bonded to a plurality of LED dice that are mounted to the submount and the submount and the optical element have approximately the same coefficients of thermal expansion. Alternatively, a number of optical elements may be used. The optical element or LED die may be covered with a coating of wavelength converting material. In one implementation, the device is tested to determine the wavelengths produced and additional layers of the wavelength converting material are added until the desired wavelengths are produced.

Various embodiments for providing removable, pluggable and disposable opto-electronic modules for illumination and imaging for endoscopy or borescopy are provided for use with portable display devices. Generally, various medical or industrial devices can include one or more solid state or other compact electro-optic illuminating elements located thereon. Additionally, such opto-electronic modules may include illuminating optics, imaging optics, and/or image capture devices. The illuminating elements may have different wavelengths and can be time-synchronized with an image sensor to illuminate an object for imaging or detecting purpose or other conditioning purpose. The removable opto-electronic modules may be plugged onto the exterior surface of another medical device, deployably coupled to the distal end of the device, or otherwise disposed on the device.
摘要:
A semiconductor structure formed on a growth substrate and including a light emitting layer disposed between an n-type region and a p-type region is attached to a carrier by a connection that supports the semiconductor structure sufficiently to permit removal of the growth substrate. In some embodiments, the semiconductor structure is a flip chip device. The semiconductor structure may be attached to the carrier by, for example, a metal bond that supports almost the entire lateral extent of the semiconductor structure, or by interconnects such as solder or gold stud bumps. An underfill material which supports the semiconductor structure is introduced in any spaces between the interconnects. The underfill material may be a liquid that is cured to form a rigid structure. The growth substrate may then be removed without causing damage to the semiconductor structure.
