• 19 and 20 relate to an effect light according to the invention, not shown in detail, with a “self-illuminating” perforated plate 98.
• This perforated plate 98 has a rectangular cross section and light passage openings 99 arranged in a regular box pattern. Some of the light passage openings 99 are kept free so that light can pass through The other part of the light passage openings 99 is provided with light-emitting diodes 100, 101, which can be activated and deactivated individually via a control device, not shown, together with the associated programming, and which are present as a light source directly on the perforated plate 98.
• Each light-emitting diode 100, 101 is seated in one Light passage opening 99, wherein it is fastened to the webs 102 of the perforated plate 98 surrounding this light passage opening.
• a free and a light passage opening 99 provided with a light emitting diode 100, 101 alternate.
• the control device or programming provides that - as can be seen in FIG. 19 - a number of light-emitting diodes 100 can be activated (these light-emitting diodes 100 are shown as black boxes), so that they light up as a whole and thus as Font, image and color information of the capital letter “H” is visible.
• FIG. 19 a number of light-emitting diodes 100 can be activated (these light-emitting diodes 100 are shown as black boxes), so that they light up as a whole and thus as Font, image and color information of the capital letter “H” is visible.
• the other light-emitting diodes 101 do not light up, that is to say they are deactivated (these light-emitting diodes 101 are identified as a box with an “X”). After a certain time, the light emitting diodes 100 forming the letter “H” can be deactivated and the remaining light emitting diodes 101 can be activated.
• this embodiment can be modified in many ways. Almost any font, image and / or color information can be generated with the light-emitting diodes and numerous sequences for visualizing this information can be achieved by the control device or programming. Likewise, such light-emitting diodes can be attached to the base plate and / or to further perforated sheets of an effect light. As already described elsewhere, the information conveyed in this way can in particular be superimposed over time.
• an effect light 103 in which both a base plate 104 and a perforated plate 105 are provided, is described below with reference to FIGS. 21 to 23.
• the design of the effect lamp 103 is comparable to that of the effect lamp 39 from FIG. 8, so that reference is made to the relevant statements in this regard.
• the perforated plate 105 is designed in the same way as the perforated plate 98 according to FIGS. 19 and 20. It accordingly has light-emitting diodes — not shown in FIG. 21 — which, when activated, make the letter “H” or the letter visible Font, image and Color information 106 serve. The same applies to the letter “D” or the font, image and color information 107, which can be made visible on the base plate 104.
• FIGS. 24a-b, 25a-b and 26a-b illustrate the optical effects that result when viewing the effect lamp 103.
• the arrangement of FIGS. 24a-b, 25a-b and 26a-b corresponds to that of FIGS. 10a-b, 11a-b and 12a-b, so that reference is made to the statements made above.
• 24a-b show the image that results for the viewer when the light-emitting diodes of the base plate 104 are deactivated and the light-emitting diodes of the perforated plate 105 are activated. In this state only the letter "H” is visible.
• FIGS. 26a-b The reverse case is shown in FIGS. 26a-b; the LEDs on the base plate 104 are activated, whereas the LEDs of the perforated plate 105 are deactivated. It is consequently only that Letter “D" visible.
• 25a-b relate to the case in which the light-emitting diodes of the base plate 104 and the perforated plate 105 are activated at the same time. This leads to an overlay of the letters “H” and “D” or the font, image and color information 106, 107.
• an effect light 108 is shown in a cylindrical closed construction. It stands on a foundation 109 in the manner of a column. Furthermore, it has a cylindrical or tubular base plate 110 and a cylindrical or tubular perforated plate 111 surrounding it. Since the diameter of the perforated plate 111 is larger than the diameter of the base plate 110, the perforated plate 111 and the base plate 110 are spaced apart, as a result of which the annular space 112 is formed. The longitudinal axes of the perforated plate 111 and the base plate 110 lie on a line. At the upper end of the columnar effect light 108 there is an opaque, disk-shaped cover 113, the diameter of which is exactly the same as the outer diameter. Knife of the perforated plate 111. The cover 113 also serves as a holder with which the base plate 110 and the perforated plate 111 are rigidly connected.
• a light source 114 which is circular in shape in accordance with the circular shape of the space 112. As a result, room 112 is illuminated all around from above.
• Light passage openings 115 are formed in the perforated plate 111. Font, image and color information (not shown in the drawings) on the base plate 110 and the perforated plate 111, together with the lighting conditions inside and outside the effect lamp 108 and, due to the cylindrical construction, cause interesting optical effects depending on the location of the viewer.
• FIG. 29 shows a lighting device 116, which is composed of four effect lights 117, 118, 119 and 120, each with a light source 121, 122, 123 and 124.
