Definitions
- the present invention relates to an LED emitter unit with at least two LED emitter modules and with a connection for the electrical power supply of the LED emitter modules, wherein the LED emitter modules each having at least one LED for emitting UV radiation of a wavelength below 430 nm or are equipped by IR radiation of a wavelength above 780 nm.
- the invention involves the use of such an LED emitter unit.
- Previous LED emitter units form self-contained units with their own electrical connection and with connecting means for producing a positive or positive connection in a mounting frame. Depending on the design and number of integrated LED lamps, one or more cables are required for the production of the data and power connection.
- the LED emitter unit for UV curing of printing inks known from EP 2 851 637 A1
- a plurality of LED emitter modules are each equipped with a multiplicity of LEDs for emitting UV light, which are arranged next to one another in a row and in a plurality of LED zones are grouped. Each LED zone can be switched on and off independently of the others and can be controlled with regard to UV power, intensity, wavelength or radiation duration of the LED spotlight modules combined in it.
- the number of electrical and mechanical connections increases with the number of lamps of a multi-beam LED emitter unit.
- the installation and removal of the lamps for cleaning, maintenance or replacement involves a great deal of wiring and time. It can easily lead to connection errors or loose contacts
- Spotlight units with permanently installed lamps are usually completely replaced, even if only individual components are defective. Because the replacement of defective components is tedious, so that usually a new complete emitter unit is used to avoid long downtime.
- the invention is therefore based on the object to provide an LED emitter unit that is easy to maintain and assemble, which reduces or avoids the mentioned cabling and uses the available space optimally.
- each LED emitter module has a housing equipped with a radiation exit window and is designed as a plug-in module for a docking station, wherein the docking station at least one connecting means for producing a positive has mechanical connection with the housing and a plug-in element of an electrical plug connection, and that the housing has a rear housing side, which has a corresponding to the connecting means mechanical counterpart and a corresponding with the plug element of the electrical connector counter element, wherein the connecting means of the docking station and the corresponding mechanical Counterpart of the back of the housing are arranged so that the production of the positive me- chanical connection also causes the production of an electrical connection between the plug element and counter element.
- the LED emitter unit according to the invention comprises a plurality of modular plug-in modules, which are also referred to herein as "LED emitter modules” or “individual modules”.
- Each of the modules comprises a separate housing in which at least one light-emitting diode (LED), but preferably a plurality of LEDs, is accommodated.
- the housings of the LED radiator modules are arranged next to one another, for example.
- the module-like construction of the LED radiator unit according to the invention has the advantage that any format widths for the irradiation starting from an LED radiator module housing with a small standard size can be obtained by joining several of these individual modules can be provided.
- Each LED radiator module preferably comprises a plurality of LEDs which may be divided into one or more segments.
- the segments are controlled separately from each other; in particular switched on and off and adjustable in their radiation power, for example, dimmable. This adaptability makes it possible to replace a failed LED radiator module with a given nominal power by another LED radiator module with a different nominal power, without the control electronics must be replaced.
- the docking station also referred to as "backplane” based on similar components in computer and electrical engineering
- the distribution of the electrical supply and preferably also the data transmission Only this docking station has a construction adapted to the specific application of the emitter unit, namely that it has a lateral extent that is at least as large as the format width of the substrate to be irradiated and that it is provided with a number of docking points.
- the individual modules are designed as plug-in units for the docking station, which corresponds to the number of individual modules required to cover the format width.
- passively cooled LED spotlight modules are used. The passive cooling of the spotlights takes place without forced cooling and requires no electrical components.
- the modular concept proves itself especially for the use of liquid-cooled or air-cooled LED spotlight modules. Because the supply of the gaseous or liquid coolant can be performed centrally via the docking station. For example, in air cooling, the suction or removal of the cooling air can also be done via the docking station.
- the docking station is a passive component that essentially provides a mounting wall facing the LED spotlight modules.
- the mounting wall is provided with connection and connection elements for the mechanical and electrical connection of the LED spotlight modules.
- the LED spotlight modules occupy slots on the inside of the docking station.
- the cabling is to be carried out only once and takes place essentially on or within the mounting wall.
- the internal power distribution of the radiator unit takes place for example via a power distribution rail along the mounting wall.
- the power distribution rail is firmly integrated into the design of the radiator unit and thus no additional component.
- the data distribution is preferably carried out via a data line running along or inside the mounting wall. On one side or on both sides of the mounting wall, a lateral cap can be provided.
- the individual LED spotlight modules are completely equipped without their own connection cables for power supply and data transmission.
- the modular design of the emitter unit offers the possibility of greatly reducing the number of cables required. Assembly, maintenance and replacement of individual modules are even easier than replacing a complete emitter unit. Errors in the production of cable connections are excluded. If a single LED spotlight module fails, it can be replaced in a short time and without much effort. It is not necessary to return the entire radiator unit to the manufacturer for repair or to appoint a service technician. This eliminates maintenance costs and downtime is reduced.
