Definitions
- the invention relates to a device for coloring and / or partially blocking the light from light bodies, such as incandescent lamps or fluorescent tubes.
- the device comprises a cap made of heat-resistant material which can be arranged around the light body or pushed over the light body, the cap being elastic and elastic
- Light body is formed at least in sections.
- the cap is transparent or translucent and colored with the desired shade.
- the cap is made of opaque material and has openings through which light can pass. This makes it possible to create special lighting effects.
- a preferred embodiment of the device is that the shape of the cap is tapered from a base in the shape of an arc.
- the base area is advantageously provided in a polygonal manner.
- a light shield can be provided on the base surface in order to prevent radiation from a light-impermeable cap with openings downward. This light shielding can preferably be screwed onto the lamp socket or can be glued or plugged onto it. Further preferred features can be found in the following description, the patent claims and the drawings.
- FIG. 1 shows a side view of an embodiment variant of the invention and FIG. 2 is a top view.
- 3 is a side view of a further embodiment variant of the invention with a partially sectioned illustration.
- 4 is a side view of another embodiment variant with a cut cap and
- FIG. 5 is a section along line V-V in FIG. 6 to 8 show further exemplary embodiments in a partially sectioned view and
- FIG. 9 is the view of the cap from the direction IX in FIG. 8.
- a light bulb 2 is screwed into the lamp holder 1 as a light body.
- the cap 3 according to the invention which here consists of a colored transparent or translucent material, is attached to the light bulb 2. This material is sufficiently elastic and dimensioned so that the cap on the glass bulb 4 of the bulb 2 holds by itself.
- the shape of the cap 3 is based on a polygonal base surface 5, from which cap surfaces 6 tapering towards the top are provided.
- the cap surfaces 6 rest only in sections on the glass bulb 4.
- Flow channels for the heated air are formed on the edges 7 between two abutting cap surfaces 6, so that the hot air can escape.
- the material is preferably a heat-resistant plastic, as is commercially available. Such plastics tolerate temperatures up to 200 ° C and more.
- the number of edges 7 of a cap can be adapted as required.
- the base area 5 can also be round or rounded without edges.
- the cap 3 is made of opaque or at least strongly light-attenuating material with openings 8. These openings can either be formed by continuous bores or recesses, or the cap can be made of a transparent or translucent material exist, which is partially opaque coated or colored.
- a light barrier 9 which covers the base area 5 and is screwed onto the holder 1.
- the openings 8 can also be designed, for example, in the form of motifs, as a result of which desired light effects are produced. Such lighting effects are, for example, a starry sky, rip points, light strips, animal motifs or cartoon characters.
- the device according to the invention can always be reused and is easy to replace with a different color.
- the light bulbs can be easily replaced and, after inserting the new light bulb, the cap can be replaced with the same color.
- the caps can be dimensionally adapted to the light bulbs or light bodies of other types, such as fluorescent lamps or fluorescent tubes, so that they can be easily plugged on and yet hold sufficiently firmly.
- the cap can be sealed against moisture and thus the shielding can also be used for garden lighting.
- the light shield 9 is preferably designed in such a way that it overlaps the cap and acts as a water-repellent roof when the bulb is arranged downward.
- FIG. 4 shows a further exemplary embodiment in a representation analogous to FIG. 1.
- the cap 3 made of heat-resistant plastic is provided with projections which are designed as knobs 11 and project inwards towards the light body 2.
- the cap 3 is formed here with a round cross section.
- the knobs 11 are distributed over the circumference and hold the cap 3 on the light body 2, which has the shape of a light bulb.
- the necks 11 serve on the one hand to fix the cap on the light body and on the other hand can serve to let the cap 3 rest on the light body 2 only in sections.
- the cross section of the cap 3 can also be polygonal, as shown in Fig.2.
- FIGS. 7 to 9 show caps according to the invention for light bodies in the form of fluorescent tubes.
- a fluorescent tube 10 which is equipped with contacts 14 on the end faces.
- the cap can be pulled over the fluorescent tube 10 like a stocking and can also be colored or provided with openings. If ventilation is required, the cap 3 can be provided with inwardly projecting knobs.
- FIG. 8 shows an embodiment of a cap for fluorescent tubes, the contacts 14 of which are arranged on the side.
- the knobs 11 are shown in this advice guidance example.
- the image according to FIG. 9 results.
- the cap 3 has a longitudinal section 13 through which the fluorescent tube 10 can be inserted laterally.
- the Ausneh openings 15 serve to receive the contacts 14th
