Th« problem addressed by the invention is solved in addition by a device for drying a coating, comprising a lamp according to the present invention. The iamp according to the present invention is partieUisHy weii-suited for this, since it combines high irradiation intensities with flexible and especially compact structural shape, in a preferred further development, a flat substrate bearing the coating to be dried and the iamp can thereby be moved towards each other in a conveying direction, wherein the iamp extends in a transverse direction at least partially over a width of the substrate and is arranged at a defined distance above the substrate, This is aiso understood to mean also a rastering delineation of the substrate surface area in several paths. For exempte, the substrate can be a printed product, which is coated in a printing machine with imprinted lacquer or another substance.

The problem addressed by the invention is aiso solved by the use of a tamp for drying s coating according to the present invention, preferably in a printing procedure,

Further advantages and features of the invention result from the embodiment described below as weil as from the dependent claims.

Two preferred embodimeriSs of the invention are described below and are explained in detail by means of the attached drawings Fig. 1 shows a schematic representation of a first embodiment of foe invention.

Fig, 2 shows a schematic representation ol a second embodiment of the invention. À iamp according to foe present invention as per Figure 1 comprises two LED modules 1, wherein each of the modules 1 is mounted bn a cooiing eiement 2 in a fiat, thermally conductive connection. The modules 1 comprise in each case a plurality of LEDs 3, which are distributed in a raster over a moduie surface area running perpendicular to the drawing plane. The LEDs 3 are mounted together with further electronic components (not depicted) on a planar support 4, whereby overall in each case a Chip-on-Board moduie (COB) is formed, The modules 1 extend in a fengitudfeai direction running perpendfcyiar to foe drawing plane and in a vertical direction, which In the drawing of Figure 1 runs from fop to bottom and corresponds to an exit direction torn foe iamp. The main radiation direction of the LEDs fous corresponds to a transverse direction, which in foe drawing of Figure 1 runs from tett to right.

The sides of foe modules 1 equipped with LEDs are opposite each other, wherein a reflector 5 is arranged between foe modules. The reflector 5 comprises two reflector surface areas 5a. 5b. wherein each of foe reflector surface areas in the present case is planar and is inclined at an angle of 45® to the plane of the in each case opposite module. Thus, a light ray {main radiation direction) exiting from an LED at 9Q* to foe respective moduie plane is deflected by foe respective reflector surface area 5a, 5b, at an angle of 90° and leaves foe iamp through an exit opening in an exit direction parallel to the vertical direction. The reflector can be designed in any way desired, for example, as a prism, as a glass mirror or as a mirror plate, in each case foe appropriate surface treatment can thereby exist to minimize tosses.

On the modules 1 a primary optical system 8 is «ranged, which is designed as a foil-surface coating of foe modules 1. The primary optical system has In each case Senses 9 right on the individual LEDs 3, by means of which a large opening angle of foe emitted light is bundled and is directed via the deflection by the reflector 5 to aforget surface 10 {see depiction and analogously running optical paths in Figure 2). A predominant bundling of the rays into a structure in the form of a straight tine running in the longitudinal direction thereby occurs in the target surface 10. The irradiation intensity by foe lamp on this structure is significantly more than 2W/ctn2.

The exit opening 6 is covered by a transparent protective disc 7. which in foe present case has no deflecting effect on the optica! path. However, in principle* the protective disc can aiso be designed as a component of foe optical system.
