An LED lighting device or LED lamp comprises one or more LED packages, and a switch comprising at least two selectable positions. At least one selectable position corresponds to a set operating mode and one selectable position corresponds to a configurable operating mode. When the switch is in the selectable position corresponding to the set operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, the one or more LED packages continue to be operated in accordance with the predefined operating light qualities corresponding to the set operating mode. When the switch is in the selectable position corresponding to the configurable operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, operation of the one or more LED packages is modified in accordance with the user-selected operating light qualities.

The invention relates to a lamp module (10) which is designed to be used as an immersion radiator in photochemical reactors. The lamp module has a support body (3) with at least one light-emitting diode (LED) (1), a head part (12) for electrically connecting the at least one LED (1) and for mounting the support body (3), and an immersion tube (11) that delimits an area (19) in which the support body (3) is arranged together with the at least one LED (1). The area (19) delimited by the immersion tube (11) is filled with an electrically non-conductive liquid (100), which is transparent to the wavelengths of the radiation emitted by the LEDs (1) of the lamp module (10), such that the at least one LED (1) is completely immersed into the non-conductive liquid (100), wherein the head part (12) has connection lines (18, 18) which communicate with the area (19) for supplying and discharging the non-conductive liquid (100), and the support body (3) is designed as a heat sink which delimits at least one internal fluid path as a supply section (4) for the non-conductive liquid (100). The supply section (4) is connected to one of the connection lines (18, 18′) via the head part (12) and opens into the area (19) on the support body (3) side facing away from the head part (12). The invention additionally relates to a photoreactor which is equipped with a corresponding lamp module.

A method of dimming an LED luminaire and a dimmable LED luminaire includes two pluralities of LEDs. The first plurality emits electromagnetic radiation at a first frequency to react with a remote phosphor and provide a phosphor illumination. The second plurality of LEDs are phosphor LEDs that emit phosphor electromagnetic radiation at a second frequency to react with the remote phosphor and provide double-phosphor illumination. The phosphors and LEDs are configured to produce specific color points when the LEDs are at full power and at full dim. When the luminaire receives a dimming signal, the first plurality of LEDs dim the phosphor illumination over a majority of the luminaire's illumination range, but the second plurality of LEDs continue to receive constant current and provide undimmed double-phosphor illumination over the majority of the luminaire's illumination range.
