Definitions
- the invention relates to a lamp for two lamps according to the preamble of the claim 1.
- the two lamps are in particular on the one hand Compact fluorescent lamps and the other to a low-voltage halogen lamp.
- Such lights are from the catalog of the company ERCO (edition 1996/97, pages 328-331).
- the round ceiling recessed lights shown there are Fluorescent lamps near the bottom of a cup-shaped outer reflector arranged. In front of the fluorescent lamps is a smaller internal reflector, the is also open to the opening of the outer reflector and in which a Low-voltage halogen lamp is located.
- Slats attached by the outer reflector is divided into several cells.
- the fluorescent lamps their light only on the fins, the outer reflector and the outside of the inner reflector falls, one even room lighting, while the low-voltage halogen lamp, the light is reflected exclusively by the inner reflector, an accentuated light distribution results.
- a luminaire which has the features of claim 1 has dissolved. Also with this lamp is near the back wall of a cup-shaped outer reflector arranged a first lamp. Farther away from the Rear wall is a smaller, also cup-shaped inner reflector, in the another lamp is arranged.
- the luminaire according to the invention is distinguished in particular the fact that the inner reflector is teillicht triminer, so that a Part of the light of the second lamp can also fall on the outer reflector.
- the construction of the Lamp can also be simplified in that the second lamp together with the inner reflector attached to a at the rear wall of the outer reflector Suspension is attached so that no fins or other such Suspension parts are needed that affect the light of the first lamp disturbing could.
- the different lighting effects are significantly affected by the Transmission properties of the inner reflector determined.
- the light shown is formed in this case to a ceiling-mounted luminaire. However, it can also be used as surface-mounted luminaire, surface-mounted luminaire or pendant luminaire be executed.
- a main component is the defining the basic form of the lamp, cup-shaped and diverging to its opening outer reflector 1, in section square is formed.
- In the rear area of the outer reflector 1 are in substantially parallel to the rear wall 2 of the outer reflector one or more rod-shaped compact fluorescent lamps 3 arranged so that a possible uniform illumination of the outer reflector 1 is achieved, wherein the individual However, phosphor rods do not cut the central axis 4 of the lamp. Instead of rod-shaped fluorescent lamps 3 would of course also use U-shaped Lamps conceivable.
- the driving of these fluorescent lamps 3 takes place in a known manner via one or more external, not shown electronic ballasts (ECGs).
- ECGs electronic ballasts
- the inner wall of the outer reflector 1 is formed facet-like. Its opening is surrounded by an edge 9, which in the installation of the light on the ceiling rests.
- a rod-shaped suspension 5 which extends along the central axis 4 to the opening of the outer reflector. 1 extends.
- a diffuser. 6 whose shape is approximately the cross-sectional shape of the outer reflector 1 in this Height equals approximately square.
- This diffuser 6 can, for example be formed by a scattering surface or a prism structure and should ensure that the fluorescent lamps 3 are not directly visible, creating possible glare effects be avoided and at the same time a more uniform illumination is achieved.
- the diffuser 6 instead of the suspension 5, the diffuser 6 but also on the inside of the be attached outer reflector 1.
- the rod-shaped suspension 5 also a low-voltage halogen lamp 7 attached, which is also from a cup-shaped inner reflector. 8 is surrounded, which is circular in cross section.
- This inner reflector 8 is in Contrary to the totally reflecting outer reflector 1 partially transparent. Be Structure as well as its effect for the different lighting effects is then explained in more detail. Due to the along the central axis 4 extending suspension 5, at which the low-voltage halogen lamp 7 and the inner Reflector 8 are fixed, more suspension parts, such as slats or the like omitted. The light reflected from the outer reflector 1 becomes light thus not affected by any additional components in a disturbing way.
- the other components of the lamp are primarily used to power the Both lamps or the holder of the lamp in the ceiling and are in their Funktoingar well known. It should therefore not be further in the following To be received.
- the main responsible component for the lighting effects is the partial translucent inner reflector 8, which is designed as a glass dichroic cold light reflector.
- the cup-shaped glass jacket is vacuum in about 50 alternating Reflection layers of titanium and silicon dioxide vaporized.
- the resulting Surface reflection is about 98%. That of the low-voltage halogen lamp 7 radiated light is therefore largely reflected by the inner reflector 8, while only a small proportion falls on the outer reflector 1.
- the permeability of heat radiation without the use of Infrared filters and is designed so that only certain parts of the color spectrum be transmitted through the inner reflector 8. This will be a Color temperature reduction of the emitted light from 3800 K to approx. 2500 K. reached.
- the transmitted and reflected by the outer reflector 1 light component has thus a slightly different color composition.
- the individual facets of the outer Reflectors 1 then serve to further refine the color reflections into individual points of light disassemble, increasing brilliance.
- Fig. 2a only the fluorescent lamps 3 are turned on, while the low-voltage halogen lamp 7 is turned off.
- the light emitted by the fluorescent lamps 3 light passes through the diffuser 6 and leaves the lamp, in which case essentially three Light paths are conceivable.
- the light beam 11 leaves the light undeflected, while in the second case 13 of the outer reflector 1 at least is reflected once.
- the third possibility is that the beam 12 on the Outside of the inner reflector 8 meets, there is reflected and then the light leaving, of course, at least once more on the outer reflector 1 can meet.
- the simplest option is the undeflected beam 14.
- the second Case is when a light beam 15 hits the inner reflector and there in a reflected beam 15a and a transmitted beam 15b is shared.
- the Color composition of the reflected beam 15a substantially corresponds that of the undeflected beam 14, that is the characteristic composition the low-voltage halogen lamp 7.
- the beam 15b however, certain color components filtered out, so that the inner reflector 8 seen from the outside according to his Filtering properties in a slightly different color appears.
- both the low-voltage halogen lamp 7 as well as the fluorescent lamps 3 is turned on, causing a Overlaying the previously described lighting effects results.
- the luminosity of However, fluorescent lamps 3 outweighs the previously described effect of the inner reflector 8 transmitting light beams 16b, so that a total of widely scattered and uniform room lighting 17 with the color characteristic of Fluorescent 3, and a limited bright beam 18 with the Color composition of the low-voltage halogen lamp 7 results.
- the inner reflector. 8 the lighting effects with its reflection and transmission properties targeted can be changed. It would be conceivable, for example, a higher Transmittance to select or filter specific color components with it. It could also the inner reflector 8 itself inside and / or outside faceted be constructed. On the other hand, the outer reflector 1 may instead be faceted also have a smooth surface, which then, however, a further decomposition the light rays are eliminated. Furthermore, instead of the fluorescent lamps and the Low-voltage halogen lamp also other lamp types can be used.
