Definitions
- the invention relates to outdoor LED and street lights, which are used in uniform and usable for different power classes identical basic structure for different lighting purposes.
- LED outdoor and street lights have the problem that even when using identical design lines for different power classes respectively
- the luminaire housing consists of continuous
- Aluminum profiles which is divided into three parts only for reasons of manufacturing costs, which have a longitudinal separation (two lateral lamp shells and a middle lampshell).
- the profiles as a housing are therefore continuous and integrally formed over both functional spaces, whereby no thermal separation of the two functional spaces lamp shell for the LED bulbs and
- Lamp shell is given for the control gear and terminal compartment. A heat flow between the two functional spaces can therefore
- Water pipes can be cooled.
- Cooling fins and their arrangement at the top of the lamp are negatively influenced by the necessary construction heights of the ribs and their arrangement on the top and the already mentioned problem of a limited
- Embodiments of the housing frame design which thermally largely isolates the LED module with its housing in various, more or less spaced arrangements from that portion of the LED driver and wiring housing, with the aim of providing a maximum surface area for ambient air flow around create.
- Luminaire housing which is thus the goal of the claimed in the present invention solution to represent a one-piece and consistent design uniform lamp head, extremely leaves. Furthermore, this solution in turn also adheres to the disadvantage that the heavily ribbed surfaces over time dirty and the outer geometry is fixed by the housing design immutable.
- the still known document US 2012/0 262 917 A1 describes a street lamp with integrally formed luminaire housing with internally spatially separate installation spaces for the LED system and the control gear and terminal compartment (see section [0062]).
- the externally extended fins as cooling elements are integrated into the luminaire housing (see section [0047]).
- the LED module as a light source uses its own optical chamber with its own housing, which can be integrated into the space provided and is autonomous and also interchangeable. Disadvantages compared to the claimed in the present invention
- Terminal space is not prevented, the housing version in turn with external cooling fins and their execution in the sense
- Object of the present invention is therefore to provide a LED exterior and street lighting, the essential components, such as LED operating room and space for accommodating other technical functional elements, such as LED operating device, power terminals, etc., regardless of the power class of each used LEDs are always identical executable. This eliminates the need to make separate housing for different performance classes in a vorgebaren frame and vorzuhalten.
- the essence of the present invention is that an LED module assembly is hermetically sealed housed in a separate LED operating room, followed by a second functional space for separate and also hermetically sealed recording of network equipment, power supply terminals and other means necessary for operation followed and both mentioned Operating and functional spaces are covered by an outside of the housing of said spaces exchange and adaptable in the surface cooling surface.
- Fig. 1 shows a basic embodiment of the invention in
- FIG. 1a the embodiment of Figure 1 in bottom view.
- Fig. 2 is a side perspective view of operating and
- Fig. 3 is a detail of a specific embodiment of the
- FIG. 1 a basic embodiment of the invention in an exploded view with all the essential elements is shown.
- an LED operating room 1 is initially visible, into which an LED module assembly 11 with a plurality of LEDs, not designated individually, can be introduced, which is hermetically sealed with a cover 13, which contains a light exit window, so that this module part is sufficient in itself protection classes of at least IP66.
- a cover 13 which contains a light exit window, so that this module part is sufficient in itself protection classes of at least IP66.
- a functional space 2 adjoining the LED operating room 1 in the right-hand part of FIG. 1 is a functional space 2, which has conventional components such as operating device (s) 21,
- Power terminal 22, etc. and unspecified or illustrated various control modules and a mast adaptation includes. All mentioned assemblies of the functional space 2 are also housed hermetically sealed within the space 2 in the above sense, so that this room is sufficient for protection classes of at least IP66, when the functional space is in the final assembled state.
- FIGS. 1 and 1a it can be seen from FIGS. 1 and 1a that the required functional assemblies (eg, 21, 22) are mounted in the functional space 2 on a mounting plate 26 which is located inside the functional space 2
- Functional space 2 can not be shown in the same manner fastened by screw domes, regardless of the specific training of each, according to the performance class in the LED operating room 1 built LED module assemblies 1 1, adapted function modules in the functional space 2. In fully assembled state of delivery is this function space for closed by a lid D hermetically sealed.
- Cooling surface 3 which is provided in the example of FIG. 1 with five tabs 31, 32, the proposed holes with the LED operating and
- Functional space 1, 2 are screwed and the required thermal heat transfer from the respective rooms in the
- the cooling surface 3 at the same time represents a variably designable design element.
- this can be achieved here on the performance-adapted training only the cooling surface 3.
- the design of the cooling surface 3 is the decisive factor here, and this can thus, regardless of the LED operating and functional space 1, 2, a variety of luminaire designs
- the LED module assembly delivers an output of approx. 74 W for an LED current at 700 mA and a system output of the luminaire at the mains of approx. 80 W. The resulting heat loss it is valid
- the electrically operated means provided in the functional space in particular the LED operating device 21, also generate
- the surface-area design of the cooling surface 3 in the region of the functional space 2 can also be correspondingly smaller.
- Another essential feature of the present invention is the thermally far-reaching separation of LED operating room 1 from
- Narrow side surfaces are thermally largely contacted only indirectly to prevent heat conduction from the warmer LED operating room 1 to the functional space 2 as far as possible.
- Example via a corner E occurs.
- the detected area which basically comes into question for the thermal contact of the two spaces.
- this area is about twice 38 cm 2 .
- the functional space 2 is at its height
- this corner region E in the mounted state however, another special feature, which consists in that when connecting LED operating and functional space 1, 2 no plan concerns the opposing surfaces, but at least on the side where the higher heat input from the LED operating room 1 will take place, namely on the roof surface 14 (see Fig. 1a ), a contacting only via web - like overhangs E1, by appropriate design of the corresponding surfaces of the
- Function space 2 are realized, so that outwards in the
- a visually closed design is formed in the interior space between the two LED operating and functional spaces 1, 2 but essentially at least in the above-mentioned area of the roof surface 14 or in another embodiment a mentioned
- this space filled with air can still be filled with a thermal insulation means 4 (for example a thermal insulation disk) which can be preset and with respect to the thermal conductivity and / or, for example, to increase the thermal conductivity
- FIG. 3 shows a sectional view along a direction indicated in Figs. 1a and Fig. 2 cutting plane C-C.
- Fig. 3 it can be seen that the functional space 2 in the hood-like the LED operating room towering area web-like overhangs E1 identifies that in not closer
- designated grooves in the respective roof surface 14 of the LED operating room 1 engage and thereby include an intermediate, here strongly oversubscribed area, in order to create a
- Airspace L which acts as a thermal insulator. It is within the scope of the invention that on the narrow abutment side 12, ie perpendicular to the just described section, the functional space 2 such web-like overhangs E1 are given, but whose effect respect. Another thermal insulation by a trapped there
- the equipped cable connection 25 for connection to the power line which is also provided with a pressure compensation valve.
- the function of these pressure compensation valves is that with varying thermal load (for example, onset of rain, etc.) a corresponding ventilation of the respective rooms takes place in order to reduce excess or negative pressure.
- the pressure compensation valve acts in the cable duct 25.
- This valve is impermeable to dust and water.
- the built-in membrane is changeable during maintenance, so at
- the LED operating room 1 is designed to protect against corrosion and contamination of the LED module assembly 1 1, as already mentioned above, as a separate and hermetically sealed room, so also correspondingly hermetically separated from the functional space. 2
- another pressure equalization valve is provided internally between the LED operating room 1 and the functional space 2 in the cable duct 24. This ensures the pressure equalization of the LED operating room 1 in the functional space 2. Due to the much smaller volume of the LED operating room 1 relative to the functional space 2 is the
- Volumen takensatz per unit time at the valve in the cable gland 25 is designed to be larger than the valve in the cable gland 24 to the LED operating room. 1
- a fifth tab 32 is provided on the front side of the LED operating room 1 in the specific example. This results in an even more optimal heat flow from the LED operating room to the cooling surface 3, and precisely where in operation the largest
- the operating ambient temperature of a commercially available LED control gear is approx. 55 ° C.
- the inventively provided thermal separation between the LED operating room 1 and functional space 2 causes the temperature in the functional space 2, under the same preceding conditions, by at least 5K is reduced and thus does not exceed the specified maximum operating ambient temperature for the operating device (usually 55 ° C).
- the specified maximum operating ambient temperature for the operating device usually 55 ° C.
- Cooling surface 3 flat and executed without additional cooling fins or heat sink, so that not only their production is extremely inexpensive (compared to heat sinks of the prior art), but also unnecessary soiling and high
- the design advantages and degrees of freedom for the design of the cooling surface 3 are varied, so that only by changing the design of the cooling surface 3 (round, oval, square, colored, etc.) can be responded very quickly to customer requirements and so easily and quickly different Design lines can be launched.
- the populated with all the modules described above and mounted LED exterior and street light can be easily mounted on site by the provided on the roadside bottom of the function space 2 lid D is opened, the fitter only the electrical connection to the mains supply via the
