Problems solved by technology

In addition, due to the low-voltage operation of the LEDs and the high current intensities required for the high irradiance power, it has hitherto not been possible to use LEDs on an industrial scale in reaction spaces which can also be several meters long in total and which have hitherto been used as diving lights. Low-pressure irradiators or medium-pressure irradiators have dimensions according to the corresponding order of magnitude

Embodiment Construction

[0041] The device according to the invention relates to an LED lamp module which is configured to be used in a photoreactor as a submersible lamp, and also to a photoreactor equipped with one or more LED lamp modules according to the invention.

[0042] In this specification, LEDs are referred to as light sources. This includes all light-emitting semiconductor components as well as organic light-emitting diodes (OLEDs).

[0043] In this description, the term "LED body" refers to an object consisting of a heat sink and a support structure with LEDs mounted thereon.

[0044] The designation "LED lamp" is used here to denote the unit consisting of the LED body and the head piece. In addition, the LED lamp module may have other components such as a diving tube surrounding the LED lamp or the like.

[0045] To be able to compete with medium and low voltage radiation sources in the photochemical field and to obtain high power densities, it may be necessary to use modules with many...

Abstract

A photochemical reactor comprising a lamp module (10) having a heat sink (3), on the outer side of which a carrier structure (2) having diodes (LEDs) (1) is arranged, and a head part (12) for electrically connecting the LEDs (1) and for mounting the lamp module (10). The heat sink (3) delimits a fluid path (a) having a feed section (4) and a return section (5) for coolant. The lamp module (10) has two immersion tubes arranged one in the other or one double-walled immersion tube (11) composed of a material that is transmissive to the wavelengths of the radiation emitted by the diodes (LEDs)(1), in which immersion tube(s) is arranged at least the heat sink (3), on which is arranged in turn the carrier structure (2) having the diodes (LEDs) (1), wherein a gap (11') formed between the two immersion tubes or the two walls of the double-walled immersion tube (11) provides thermal decoupling.

Description

technical field [0001] The invention relates to a lamp module with light-emitting diodes (LEDs), which can be used as a submersible lamp in photoreactors for carrying out photochemical reactions or also in so-called AOP (Advanced Oxidation Process) and for disinfection, and related photoreactors. Background technique [0002] The use of radiation sources, in particular UV irradiators, as submersible lamps in liquid substances, for example to sterilize water or to carry out photochemical reactions, is known from the prior art. In general, low- or medium-pressure irradiators (discharge lamps) are used in a conventional manner, which are protected, for example, from contamination of diving tubes that allow the radiation emitted or radiation associated with photochemical reactions to penetrate. Pass. The emission spectrum of the discharge lamp can be changed by suitable doping and adjusted within a certain range according to the requirements for the photochemical reaction. ...
