A retrofit light emitting diode (LED) module may include a carrier with at least one LED, a retrofit connection for mechanical and electrical contact-connection to conventional lamp holders, and an electronic system for driving the at least one LED. At least one part of the electronic system is integrated into the carrier, and the electronic system comprises a sensor system. A retrofit LED module system may include at least two retrofit LED modules and at least one control unit which regulates the retrofit LED modules in an adaptive and synchronized manner.

Integrated LED and sensor device

A light emitting device and a method for manufacturing a light emitting device, wherein the light emitting device comprises a light emitting diode (LED) emitting light in a first emission spectrum, and a composition comprising at least two components and being adapted to absorb at least a part of the light in the first emission spectrum and upon absorption to emit an up-converted light in a second emission spectrum, wherein the light in said second emission spectrum has a wavelength range lower than the wavelength range of the light in the first emission spectrum, whereby the light emitted by the light emitting device comprises a mixture at least of light in the first emission spectrum and of light in the second emission spectrum.

Light emitting device and method for manufacturing a light emitting device

The invention relates to a device and a method for controlling the light emission (i) of at least three light sources (), wherein the light emitted by the light sources () is detected in a sequence of measuring periods during a calibration phase, and calculated on the basis of the information on the brightness of each individual light source () obtained during the measuring periods. In at least one of the measuring periods, the detected light comes from a plurality of the light sources ().

Device and a method for controlling light emission

An LED module having an LED semiconductor chip mounted directly or indirectly on a platform. The platform is made from silicon and is extends laterally beyond the LED semiconductor chip having an active light emitting layer and a substrate. At least one electronic component that is part of the control circuitry for the LED semiconductor chip is integrated in the silicon platform.

LED module with color conversion layer designed for a homogenous color distribution

The invention relates to a light emitting device having a radiation emitting element, for example a light emitting diode, and a luminescent material which is able to absorb a part of the radiation sent out by the radiation emitting element and to send out light with a wavelength which is different from the wavelength of the absorbed radiation. The device further has diffusing particles which are able to scatter a part of the radiation sent out by the radiation emitting element, and/or to scatter a part of the light sent out by the luminescent material. The diffusing particles are of non-activated luminescent material, through which production is simplified.

Light emitting device with a non-activated luminescent material

A system and method for determining the local distribution of measurement variables being measured relative to or present in a predefined measurement area of a biological sample wherein in a first optical measuring process the local distribution of a first of the measurement variables is determined using a sensor film applied to the measurement area and including a luminescence indicator reacting to the first measurement variable by a change of luminescence decay time. The luminescence decay time or a quantity derived therefrom is recorded by an imaging technique as a function of the first measurement variable. In a second optical measuring process the local distribution of a second of the measurement variables is determined simultaneously or immediately following, using an imaging technique which is effective through the sensor film of the first optical measuring process.

Method and device for determining local distribution of a measuring parameter

A system for quantitative determination of the local distribution of a quantity to be measured, comprising a planar sensor film, which is applied to a measuring surface, such as the surface of a body organ, a skin area or a cell culture, and whose diffusion properties regarding a parameter to be determined are known. The sensor film contains a luminescent indicator responding to the parameter to be determined with a change of at least one optical property. The system further comprises an excitation and detection unit including means for supplying excitation radiation of at least one wavelength, an imaging detection means, preferably a CCD camera, and an evaluation unit processing the image information obtained from the excitation and detection unit. Further provided is an applicator tube to be placed on the measuring surface, whose rim facing the measuring surface is in elastic contact with the sensor film and is impervious to external radiation interfering with the detection means. At the other end facing away from the measuring surface, which may be covered with a cap, a coupling means is provided for attachment of the excitation and detection unit.

There is disclosed an optical sensor including a matrix containing a luminescence indicator whose luminescence may be quenched by oxygen. The optical sensor contains at least one agent capable of deactivating singlet oxygen and has an enhanced stability relative to oxygen.

Optochemical sensor

A measuring assembly comprises a supporting element transparent to excitation and measurement radiation, which is provided with a number of preferably different luminescence-optical sensor elements on a first boundary face. Via a second boundary face excitation radiation can be picked up, and a third boundary face is used to supply measurement radiation of the sensor elements to a detector of an evaluation unit. The direction of the excitation radiation is essentially normal to that of detection. The preferably different sensor elements are connected by a common sample channel, and optical and/or temporal separation of the measurement radiation of the individual sensor elements is provided.
