- Profile element designed heat sink.
- the luminaire is suitable, for example, as a moisture-proof luminaire or for all high-performance LED luminaires with a higher degree of protection.
- the lamp is not only suitable as a wet room light, it can for example be designed as an LED spot or the like.
- the heat sink can be formed in different shapes, for example, it can be flat, curved, curved or shaped; it can be designed, for example, as a sheet metal or as an extruded profile or as a die-cast part.
- Many functions can be incorporated into the heat sink: top and bottom structures, for example, cooling fins or fastener undercuts. Due to the improved cooling effect can be a
- the heat sink 6 may be adapted in shape to the opening 7 in the frame 5 so that it can be used both from above and from below. Alternatively, it may be formed lying on the frame 5, so as shown in the figures or inserted from below into the frame.
- the heat sink 6 can be connected or glued directly to the cover 2 by the elastic connecting element 12 - ie in effect without the frame or the first housing part 5. This makes it possible to save a component, the frame, and a corresponding connection.
- the luminaire formed in this way is particularly suitable as a disposable luminaire or "disposable luminaire.” Prior to the connection of the heat sink 6 to the cover 2, this luminaire can be wired accordingly, wherein the connection preferably takes place by means of a protective plug connection (watertight plug-socket connection).
- the interior 3 can be made sealed in this case, ie the sealing is done from the outside, either by means of foam bead that seals the circumferential gap or with suitable material, such as silicone.
- the elastic connecting element 12 may also be a foam molding, which is glued between the frame 5 and the heat sink 6.
- the luminaire may have a plurality of corresponding heat sinks, wherein the frame 5 has a plurality of corresponding openings and in each of the openings in each case one of the heat sink is used accordingly.
- the aluminum profile 6 is encapsulated directly with plastic encircling, such that the plastic 5 with the profile 6 intentionally does not enter into a composite, but under heat, a gap between the components 5, 6 is formed.
- the joint is circumferentially sealed inside with a foam bead.
- a film-like permanently elastic material 100 is conceivable that enters into a composite with both components 5, 6 and the joint seals elastically. Operation: The heat sink (KK) 6 is inserted into the mold and overmoulded with plastic. Now, not the space between aluminum 6 and plastic 5 elastically connected, but the elastic member 100 is applied to the joint (joint, seam).
- the aluminum sheet 6 can be flat, round, bent all around, with tabs for a peripheral sealing edge and
- TPE component Seal options
- the aluminum profile 6 is machined, namely the ends 61, 62 are chamfered or reworked, as already described above with reference to FIG. 4a above by way of example.
- the cooling ribs 65 and the platinum carrier profile can be cut off on the front side in order to allow a circumferentially homogeneous seal (also on the front side).
- a frontally milled KK profile 6 is shown. It may be advantageous to rework the profile 6 on the front side in order to obtain a sealing plane around the circumference.
- a tool shell seals directly on the aluminum heat sink 6 (a sealing edge is pressed onto the component);
- a sealing edge is pressed onto the component;
- a beveling of the KK profile 6 may also be desired or advantageous from a design point of view.
- the heat sink 6 may be designed as a diecast part, which is elastically glued into outbreaks in a plastic tub 5 or is.
- the advantage here In existing damp-proof cubicle luminaires, the same die-cast part can be glued to the tub in different numbers. The cooling effect is optimized by appropriatedefmnen in the flow direction.
- the die-cast part stands inside the tub and the platinum carrier plate is screwed to the die-cast body.
- the KK 6 is therefore not made of a profile or sheet, but of a die-cast part. In particular, it can also consist of several die-cast parts onto which the support plate is screwed or is. As schematically in Fig.
- the cooling fins 65 'in a die-cast part in contrast to a profile, transversely to the light, so be designed more favorably with respect to the flow.
- the ribs run lengthwise and so far less favorable for a corresponding flow profile.
- the heat sink 6 can be designed in two parts, in particular in such a way that an external KK 601 and an internal KK 602 are formed as a result.
- the outer KK 601 can protrude beyond the breakout and in particular can be pulled laterally “downwards” in order to enlarge the cooling surface, whereby the outer KK 601 can be glued to the trough 5, wherein the inner KK 602 has screw channels 605 with which
- This variation is flexible: different KKs can be applied, depending on the application
- a two-part KK can be used to clamp an inserted seal 700, for example made of PUR, with the necessary contact pressure.
- the plastic frame 5 is inserted with the seal 700 between the two KK components 601, 602 and through the
- a two-part KK also offers the advantage that different components can be used.
- the inner KK 602 can be equipped with different LEDs 4 or
- the outer KK 601 can, depending on the application of the lamp, for example, with different cooling capacity
- KK 601, 602 are equipped. Furthermore, the use of a two-part KK offers manufacturing advantages.
- the joint of the KK 601, 602 is flat and can be easily inserted into a tool.
- profiled aluminum profiles 6 profiled on both sides it is conceivable that an insert part is pressed in on the end face after pulling the foam bead, which serves to press the sealing / adhesive foam against the contours of the profile 6 and thus to increase the effective adhesive surface.
- profiled profiles 6 on both sides it is often more difficult to approach the areas to be sealed circumferentially (with the
- the foam bead is pulled around the area to be sealed and then, even before the foam hardens, an insert is pressed onto the foam bead, so that the foam is pressed into the space to be sealed and cured there.
- the TPE it is conceivable that it forms part of the housing (surface of the luminaire). The TPE can - in comparison to a foam bead - one in the
- Openings 500 may be provided, so that only one foam bead 12 ' , adjusted low viscosity, is sufficient to connect the frame 5 with the cooling profile 6 and at the same time to form the sealing bead.
- Plastic frame 5 interpreted as such that the thermal expansion of the plastic 5 of the heat sink 6 corresponds. It is important that the plastic frame 5 at the contact point of the composite has contact with the ambient air and is not below the heat sink 6, as would be the case in the sketched in Fig. 2 version with high edge. In this variant, it must be ensured that the stresses in the frame 5 can be reduced:
- the heat sink 6 and the joint on the frame 5 expand approximately the same, the temperature transition to the joint also includes a length extension transition and thus stresses. D. h. That on the shock side strain areas are constructively introduced into the frame 6, possibly even over the entire length.
- a type of drapery may be provided, which may flatten itself in the course of thermal expansions in order to compensate for the stresses.
- Plastic part 5 is artificially enlarged and it is therefore more flexible.
- the groove or the frame 5 ' can also be injected from TPE onto the cooling profile 6. It should be noted here that the freedom of design on the front side is eliminated, it is advisable in this case to perform the frame 5 'only as a groove and on the front side either angularly (or with slight rounding) or to mill the cooling profile 6 frontally round , Thus, the groove and thus the cover 2 receives a rounding.
- the KK 6 is inserted into a tool and with TPE a sealing groove is sprayed onto it. It falls away the plastic frame, but suffers the creative freedom of the lamp.
