Description

The The invention relates to a luminous element with a circumferential this Plastic handling part, wherein the handling part is tubular is.

Such lighting elements with a peripheral handling part have already become known in various embodiments. It is, for example, on the DE 200 09 972 U1 and the DE 203 00 328 U1 directed.

outgoing from the aforementioned prior art, the invention the task of a lighting element with a comprehensive handling part specify that easy and cheap to assemble and usable is.

A possible solution of the task is after a first Inventive concept given by the subject of claim 1, wherein it is pointed out that the luminous element is a light-emitting diode is and that the handling part of two by longitudinal division resulting shell parts is composed. The light-emitting diode itself is a standardized, elongated and small luminous element Although preferably used but not always cheap to handle. According to the shell parts, the handling part can be cheap to be mounted on the light-emitting element. By joining the shell parts in a direction transverse to a longitudinal axis of the handling part. The comparatively small LEDs can be so conveniently surrounded with the handling part become. They are better then according to the handling part in particular decorative items such as luminous stars, luminous figures or the like.

Further Features of the invention are below, also in the description of the figures and in the drawing, often in their preferred assignment to described the claim concept already explained above, But they can also be assigned to just one or one several individual features described here or illustrated by drawings are, in particular, those of the already negotiated claim 1 or independently or in a different overall concept of Meaning.

So it is preferred that the shell parts are klipsverbindbar. she may have cooperating latching elements for this purpose. For example, plug-like projections on the longitudinal connection surface are preferred of a shell part and associated mounting holes on the Longitudinal joint of the other shell part.

Further is preferred that the shell parts with a longitudinal hinge connected to each other. You can be so one-piece, For example, in the plastic injection molding, be prepared. For assembly They can be unfolded without the assignment the two shell parts is lost to each other.

Further It is also preferred that one or both shell parts have a support extension are formed. Such a support extension can, for example, a transverse to the longitudinal extent on the shell part outside be a prominent thorn. Preferably, two are in opposite directions to each other extending holding parts on each one of the shell parts. The In the assembled state, shell parts not only form inside a tubular free space, but are also one substantially cylindrical outer shape.

you can have an inlet opening and an outlet opening differ. The inlet opening is that of the diode head, which separates light when energized assigned. The outlet opening is according to the opposite end, to lead out the connecting wires, provided. The support extensions are considered over the length of the handling part provided offset to the outlet end provided. alternative or in addition to those already described Thorn-like support extensions can also be a hook-like Mounting extension be provided. This one can also be special be arranged so that it is assigned to the outlet end outside attaches to the outer surface of the handling part and extends beyond the exit end. In its areal extent, therefore, it extends substantially vertically to the dome-like support extensions.

The Inlet and / or outlet opening of the handling part is preferred over an inner opening width formed of the handling part tapers. This results a particularly favorable support function with respect on the penetrating LED. Next is also preferred that the Inlet and / or outlet one or more radially having inwardly projecting dividing fingers. This is special with regard to the outlet opening preferred. So can the leads are clamped cheap.

The light-emitting diode has a light-emitting diode head and a preferably tapered diode extension on the other hand. Both are preferably uniformly formed as a glass body, wherein inside the diode head of the LED crystal (semiconductor) is arranged and the connections are formed on the cathode and anode side. It also results in a lens effect through the diode head. The diode head is in relation to the support ele Preferably arranged such that it projects at least partially beyond the inlet end of the support member. More preferably, it is completely over the entrance end.

From Meaning is also with respect to the support member, the preferably sprayed, for example, from a milky appearing plastic is that some interaction with the light that comes from the Diode head exits, results. The lighting effect will be in this area in terms of control, so in particular for the aforementioned decorative items in addition This results in a favorable light effect.

Further is preferred that the LED at least in its inside The handling part extending area surrounded by a shrink film is. This favors the entrapment of the light-emitting diode in the handling part.

below the invention is further described with reference to the attached drawing, which, however, represents only one embodiment, explained. Hereby shows:

1 a light-emitting diode received in a holder handling member;

2 the handling element in unfolded form;

3 a representation according to 2 but looking at the outer surface of the shell parts;

4 a non-closed handling part with inserted light-emitting diode.

Illustrated and described with reference first to 1 a lighting element 1 that consists of a light emitting diode 2 and a comprehensive plastic handling part 3 consists. The handling part 3 is elongated tube-like design. It is also externally designed substantially cylindrical.

The handling part 3 consists of two shell parts resulting from longitudinal division 4 . 5 (see also 2 ) together. The shell parts 4 . 5 are connected by clips. For this purpose, on the shell part 4 as shown one or more locking pins 6 be formed and on the shell part 5 relevant mounting holes 7 , The dimensions are chosen so that there is a tight fit.

Next are the shell parts 4 . 5 , see again 2 , by a longitudinal hinge 8th forming plastic tape connected together. They can therefore be manufactured in one piece by injection molding.

The handling part 3 has a light-emitting diode head 9 assigned inlet opening 10 and one of the connecting wires 11 . 12 associated outlet opening 13 on. The inlet and outlet openings are opposite to a free inner diameter d of the handling part 3 tapered trained. The taper is only slightly with respect to the inlet opening. With respect to the outlet opening with respect to the outer contour circular. They have a relation to a free diameter dimension d in the interior of the handling part contrast, lower free opening dimension d 'or d''. d 'or d''may be 1/20 to 1/3 less than d, whereby all intermediate values are included here in particular in 1/20-steps in the disclosure. It is further preferred here that d '' is chosen larger than d '.

At the exit opening 13 are more preferably one or more radially inwardly projecting dividing fingers 14 educated. These allow cheap the connecting wires 11 . 12 to summarize here and in addition to stabilize the arrangement of the LED inside the handling part.

It is further preferred that both shell parts 4 . 5 externally freely protruding mounting extensions 15 . 16 exhibit. These are also molded in one piece with the support member.

In addition, as is apparent from the 2 to 4 in particular also results, associated with the outlet opening 13 at least one of the shell parts 4 . 5 a bracket hook 17 formed. This extends beyond the outlet opening 13 out.

As in particular 4 can be seen, is the LED 2 from a shrink tube 18 surround. This shrink tubing provides in the region of the handling part 3 a favorable form summary of the LED. In addition, it also allows the non-slip mounting of the LED in the handling part 3 , The shrink tube 18 can be up over part of the diode head 9 extend. At the foot, it preferably extends to the outlet opening 13 or a little bit beyond that.

In the assembled state, as is clear from the 1 and 4 also yields, the diode head protrudes 2 , Preferably completely, on the assigned Endbe rich of the handling part 3 , so the entrance opening 10 , out. Together with the convenient handling by the handling part 3 is also ensured a practically unimpaired luminous efficacy.
