- centering 12C, 12D sitting in installation position inside in the end openings 2N, 20 next to the engagement hooks IOC , 10D of the primary optics 10, so that the width of the end openings 2N, 20 is thus chosen so large that centering elements of both the primary optics 10 and the secondary optics 12 are receivable therein.
- FIGS. 15A to 15C show a further embodiment of a hold-down device 2 designed according to the invention, which is constructed essentially identical to the hold-down device indicated in FIGS. 1A to 1C.
- This difference relates to the design of the hold-down outside in the region of the passage opening 2A.
- a further outer clamping surface 2Q is formed in the middle outer region of the blank holder, which extends parallel to the adjacent clamping surfaces 2H and 21.
- the modified-down device comprises two ⁇ in contrast to the first holder 2 in the central, outer region to the outer clamping surface 2Q another outer catch nose 2P, the alignment extends in the longitudinal direction of the holder 2 ⁇ to the neighboring outer detents 2K or 2J.
- the latching surfaces 2J_a, 2K_a and 2P_a are the specified External latching noses in one plane.
- the outer locking lugs 2K and 2J are resilient, while the outer locking lug 2P is rigid, since it is arranged on a rigid outer surface 2Q.
- the longitudinal extent of the contemplatrastnase 2Q is at least twice the longitudinal extension of the contemplatrastnasen 2K and 2J.
- the inventively designed hold-down 2, 2 are formed with the outer outer clamping surfaces 2H, 21 and 2H, 21, 2Q and the outer locking lugs 2J, 2K and 2J, 2K and 2P, to optics on the outside of the hold-down as in the figures 10-14 specified secondary optics, or other optics such as a covering optics, in particular a diffuser to hold or fasten.
- the tariffs mentioned ⁇ surrounded in the figures 10 to 14 secondary optics is ⁇ usually forms an injection molded part, which is maintained as described by the blank holder on the outside thereof.
- the functionality of the blank holder according to the invention is not limited thereto.
- FIG. 16 In particular ⁇ sondere to the hold-down described 2, 2 and for mounting of optics, and in particular be used Abdeckoptiken which are prepared by an extrusion or extrusion process.
- a cover 13 is shown in FIG. 16 in an end view parallel to the longitudinal axis. Visible, the U-shaped cover in the region of the lower legs on a bulge acting as an undercut outward, such that forms a shoulder surface 13 B over the entire longitudinal extent. Their inwardly directed, rounded edge forms a stop 13A, said stop and the shoulder surface with the clamping surfaces 21, 2H, 2Q and the locking surfaces 2J_a, 2K_a and 2P_a of the blank 2 and 2 ⁇ cooperate to hold the cover, whereupon will be discussed in more detail.
- FIG. 17 shows an LED assembly comprising an elongated LED board 4, a luminaire housing 8 or a device carrier arranged therebelow, wherein the hold-down device fixes the LED board 4 on the luminaire housing 8 or the device carrier, as described above.
- the LED assembly shown in FIG. 17 comprises a cover optics 13 which encloses the LED circuit board 4 and all longitudinally arranged hold-down devices 2, wherein the fastening of the cover optics embodied here as a diffuser cover to the hold-down device 2 can not be detected.
- FIG. Installation state between the covering optics 13 and the hold 2 shows.
- the outer snap-in lugs 2J, 2K and 2P engage in the step running longitudinally on the inside of the cover optics 13, such that the latching surfaces 2J_a, 2K_a and 2P_a come to rest on the shoulder surface 13B of the cover.
- the cover optical system 13 is in its side limbs in the installed state in a slightly biased state, such that the longitudinal stop 13A of the cover lens is applied to the respective clamping surfaces 2H, 2Q and 21.
- the described attachment of the covering optics on the hold-downs has the advantage that no positive connection in the longitudinal direction between the holdings and the cover is set in the installed state, so that caused by temperature fluctuations change in length of the cover can not lead to destructive tensions within the cover, since between the Hold-downs and the covering optics alone a traction is set.
- the LED assembly shown in FIGS. 17, 18 is particularly suitable for designing lamps that are very long in the longitudinal direction.
- Both the hold-down device 2 and the modified hold-down device 2 are designed for fastening the covering optics or the diffuser 13.
- the hold-down 2 can due to the rigid outer locking lug 2P an insensitive to external force attachment of the cover 13 are provided.
- the Abdeckoptik 13 is first ckung on a side legs with the associated outer detents 2J, 2K and 2P of the assigned holding-down devices over the entire L josserstre- one side in engagement brought, in which case the other side legs of the optics is pivoted out of its later installation position.
- the second side leg of the covering optics 13 comes into engagement with the complementary fastening means on the associated hold-down 2 such that the stop 13A abuts against the clamping surfaces 2H, 2Q and 21, and the shoulder surfaces 2B of the cover 13 at the associated locking surfaces 2J_a, 2K_a and 2P_a comes to rest.
- the cover on the other hand horizontally aligned to the LED board can be moved vertically downwards, whereby both side legs are resiliently pressed by the support on the holddowns outward, whereby the discourserastnasen 2J, 2K and 2P of Hold-down 2 ⁇ come to lie in the undercut and snap back both side legs of the cover 13.
- the optics can according to the invention also one or more parts be educated.
