- the frame holder 30, is stamped from spring steel, is bent in a U-shape, the Locking projections 33, 35 are arranged on a first U-leg 31. Again Representation can be seen in Figure 5, this first U-leg 31 in its lower portion bifurcated split into two sections 32, whose lower ends are bent to two locking lugs 33.
- the upper locking projection 35 In contrast, 31 is obtained by a punching of the first U-leg.
- the Both lower portions 32 of the first U-leg 31 point beyond also two bent spring tongues 34, whose function later will be explained in more detail.
- the second U-leg 36 of the socket holder 30 is for holding two Lampholders 50 provided and has for this purpose a plurality of locking holes 39, in which engage on the back of the sockets 50 arranged locking pins 51, such as in particular the illustration in Figure 2 can be removed.
- lamination element 40th This consists in Essentially from a laminating plate 42, from which a latching head 41 after extending above, for latching with one of the second U-leg 36 of the Socket holder 30 is provided inwardly bent projection 37.
- a safe Arrangement of the lamination element 40 is further by two in the Laminated plate 42 provided projections 43 ensures, which is located on the Support lower edge of the second U-leg 36 of the socket holder 30.
- FIG Laminating plate 42 then disposed below the lamp sockets 50 and prevents from the bottom of the lamp holders 50 and thus to the Lamps led lighting wiring can be seen.
- FIG Lamp according to the invention a - in the emission direction - in front of the light sources 55th arranged latching arrangement 20 to the emitted light down restrict certain angular ranges.
- the embodiment of this locking arrangement 20 will now be explained in more detail with reference to Figure 7 and Figure 10.
- the latching arrangement 20 first of a cross-section approximately semicircular back reflector 21, which surrounds the lamps in the mounting position at least partially and causes at least a small portion of the output from the lamps 55 Light is reflected to the top.
- the luminaire according to the invention achieved so that both a direct and an indirect lighting.
- a plurality of passage openings 23 are arranged, which are intended to allow light to pass in the direction of radiation.
- a pot-shaped reflector 22 on, for example, a round or a rectangular light exit opening with may have a size of about 40 mm to 60 mm in diameter.
- the juxtaposed pot reflectors 22 give the impression of a Series arrangement of several halogen lamps, whereby the lamp a special, gives a visually interesting appearance.
- the Topfreflektoren 22 arranged over a parallel to the lamps 55 Connection plate 24 connected together.
- the individual elements of the reflector assembly 20, so the back reflector 21, the Topfreflektoren 22 and the connecting plate 24 can each also be formed partially transparent, whereby additional optical effects are achieved can.
- the illustrated reflector assembly 20 is - as can be seen in Fig. 1b - preferably of a plurality of individual modules 25, which are longitudinal to the entire Reflector assembly 20 are joined together.
- An injection molding tool for producing a one-piece However, reflector arrangement over the entire length of the luminaire would be over many times more expensive than the production of several smaller individual modules 25.
- the latch assembly 20 is not otherwise through the grid holder 30 is held. Instead, the individual modules 25 are only in the Housing frame inserted and lie with lateral projections 26 and 27 (see FIG. 11 or FIG. 13) on corresponding bearing surfaces of the two lateral ones Profile elements 10 on.
- a luminaire is thus created that has a very elegant appearance and also achieved visually appealing lighting effects.
- the Assembly of the luminaire in total is compared to previous profile frame lights much easier.
