A lighting unit () comprising a phosphor element () provided for converting pump light to converted light and designed to emit conversion light at an emission surface (), and at least two pump light sources () configured for emitting pump light, wherein the lighting unit () is designed such that primary pump light emitted by a first pump light source () illuminates the phosphor element () at an incidence surface (), which differs from the emission surface (), and secondary pump light emitted by a second pump light source () illuminates the phosphor element () at the emission surface ().

Lighting unit comprising a phosphor element

The present invention relates to a light source unit having at least one LED sub light source unit. Each LED sub light source unit includes three types of LEDs: phosphor converted green LED, orange-red LED with a wavelength of 614 nm-622 nm, and blue LED with a wavelength of 460 nm-476 nm. Light generated by the three types of LEDs is mixed to generate white light.

Light source unit, an illuminating device equipped with the light source unit and medical equipment

An airfield lighting device, comprising: at least one first light-emitting diode (LED) on a first base body; a first thermally conductive tube with a heat transmission medium; a first heat sink; and a housing, in which the first base body and the first thermally conductive tube are arranged. The first thermally conductive tube is thermally coupled to the first base body and to the first heat sink. The heat transmission medium can circulate in the first thermally conductive tube, such that heat which is produced by the at least one first LED during operation can be dissipated from the first base body to the first heat sink.

Airfield lighting device

A light-emitting diode array is disclosed which has two light-emitting diodes which are connected in antiparallel with one another, and a power supply which is suitable for energizing the light-emitting diodes independently of one another in the forward direction. In addition, an optical recording apparatus and a method for the pulsed operation of a light-emitting diode are disclosed.

Light-emitting diode arrangement, optical recording device and method for the pulsed operation of at least one light-emitting diode

Optoelectronic component, having a basic body or housing (), at least one optoelectronic semiconductor chip () arranged in a recess of the basic body, and a potting composition () made of a transparent material, which potting composition embeds the at least one semiconductor chip in the recess, the transparent potting composition () being formed in diffusely scattering fashion and in particular containing diffuser particles () at which light impinging thereon is diffusely scattered.

Optoelectronic component

In a light-emitting diode carrier, a plurality of light-emitting diodesare mounted on the rear sideof the light-emitting diode carrier and project into a plurality of openings. During operation, the light-emitting diodesradiate through the openingsof the light-emitting diode carrier. A filmis applied on the front sideof the light-emitting diode carrier, said film being transmissive to the radiation emitted by the light-emitting diodes and protecting the light-emitting diode carrier from ambient influences.
