These laterally define element 8 and upwards extend, preferably until the height of relevant LED light source 2,2 ' or extend to the LED 21,22 of relevant LED light source 2,2 '.
Carrier element 9 that is that optical element 6 preferably additionally comprises a bow or channel form, this carrier element be formed in the mode of section bar shape and be parallel to longitudinal axes L and extend, wherein another part of these inner surfaces of each spatial portion section 7 of dispersing, two longitudinal inner surfaces 71,72 of namely longitudinally extending relative to longitudinal axes L are formed by this carrier element 9.By means of carrier element 9, optical element 6 advantageously can be designed to a stable structure unit.For this purpose, these laterally define that element 8 and/or LED light source 2,2 ' preferably arrange in the mode be arranged on carrier element 9.Specifically, this at least one circuit board 13 can be installed on carrier element 9.Preferably, carrier element 9 is formed in the mode of single type composition, and these two longitudinal inner surfaces 71,72 of the spatial portion section 7 making all these disperse like this are advantageously only formed by parts with regard to production engineering.
As presented by way of example from Fig. 2, carrier element 8 be preferably designed to this carrier element is extended until two contrary sides far away and side-reflector 31,32.In the example illustrated, this design makes these side-reflectors 31,32 upwards extend farther than transverse slice 33.In this case, this design is preferably so that the optical element 6 being in the state of separating with grating element 3 can be moved relative to grating element 3 with longitudinal axis by the mode guided by these two side-reflectors 31,32 with paralleling in addition.In this case, these side-reflectors 31,32 are formed as just as the guide rail for optical element 6.
Such as when being intended to the light source replacing this grid illuminating lamp, this is particularly advantageous.Specifically, when a corresponding grid illuminating lamp comprises a conventional fluorescent fluorescent tube as light source, just can replace this fluorescent tube by a corresponding module comprising optical element 6 and these LED light sources 2,2 ' especially simply.In this case, the module formed thus easily can be inserted in side in grating element 3 and to be electrically connected accordingly subsequently.In this case, this module can be made up of grating element 6 and these LED light sources 2,2 ' especially.
Further preferably, optical element 6 comprises a diffuser element 11 extraly, and this diffuser element is that optics is arranged in these LED light sources 2, between 2 ' and these light guidance units 5 effectively.Preferably, in this case, diffuser element 11 is bow with regard to the side towards these LED light sources 2,2 '.By diffuser element 11, the light sent by the LED light source 2,2 ' of these typical almost point formats just can distribute in the following manner, that is: when observing this grid illuminating lamp from outside, described light with regard to blend of colors, glare effects and form many places shades at working surface risk in seem and distribute more equably.
Fig. 5 shows the view of a schematic representation that tilt to see the visual angle of a light guidance unit 5 of grating element 3 from below, that see diffuser element 11.
Diffuser element 11 can be formed the form of a diffuser film.Preferably, diffuser element 11 is installed on carrier element 9.Further preferably, diffuser element 11 is made up of a part.
This design of optical element 6 makes the LED light source of different designs to be incorporated into especially neatly in these spatial portion sections 7 of dispersing with regard to design.Diffuser element 11 equally can be particularly advantageously selected from dissimilar diffuser element.
Grid illuminating lamp according to the present invention be particularly suitable as can send high-quality light illuminating lamp, particularly as being applicable to display workstation and there is little light output surface thus the illuminating lamp of the multiple reflectors in multiple arrangement or a grid illuminating lamp must be covered thus.
