Definitions
- the invention relates to a lamp for two lamps according to the preamble of claim 1.
- the two lamps are, in particular, on the one hand Compact fluorescent lamps and secondly a low-voltage halogen lamp.
- Such lights are from the catalog of the company ERCO (edition 1996/97, pages 328-331).
- Fluorescent lamps near the bottom of a pot-shaped outer reflector arranged.
- the fluorescent lamps 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 one Low-voltage halogen lamp.
- Slats attached by which the outer reflector is divided into several cells By optionally switching on the two lamps different Illuminations can be achieved.
- the fluorescent lamps produce their light only on the slats, the outer reflector and the outside of the inner reflector falls, one uniform room lighting, while the low-voltage halogen lamp, the light is only reflected by the internal reflector, an accentuated light distribution results.
- This object is achieved by a lamp which has the features of claim 1 has, solved.
- This lamp also has one near the rear wall pot-shaped outer reflector arranged a first lamp. Further away from the There is a smaller, also pot-shaped inner reflector in the back wall another lamp is arranged.
- the lamp according to the invention stands out in particular from the fact that the inner reflector is partially translucent, so that a Part of the light from the second lamp can also fall on the outer reflector.
- a diffuser can be provided between the first lamp and the inner reflector that ensures that the first lamp is not directly visible.
- the structure of the Luminaire can also be simplified in that the second lamp together with the inner reflector attached to one on the rear wall of the outer reflector Suspension is attached so that no slats or other such Suspension parts are needed that interfere with the light of the first lamp could.
- the different lighting effects are essentially due to the Transmission properties of the inner reflector determined.
- the lamp shown is designed to be a recessed ceiling lamp. However, it can also be used as a surface-mounted light, surface-mounted light or pendant light be executed.
- a main component is the basic shape of the lamp, pot-shaped and diverging towards its opening outer reflector 1, dei in section is square.
- the outer reflector 1 In the rear area of the outer reflector 1 are in one or more substantially parallel to the rear wall 2 of the outer reflector rod-shaped compact fluorescent lamps 3 arranged so that one possible uniform illumination of the outer reflector 1 is achieved, the individual However, fluorescent 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.
- These fluorescent lamps 3 are driven in a known manner via one or more external electronic ballasts, not shown (Electronic ballasts).
- the inner wall of the outer reflector 1 has a facet-like design. Its opening is surrounded by an edge 9, which occurs when the lamp is installed of the ceiling.
- a rod-shaped suspension 5 attached, which extends along the central axis 4 to the opening of the outer reflector 1 extends.
- a diffuser 6 is located on this suspension 5 in front of the fluorescent lamps 3 attached, whose shape is approximately the cross-sectional shape of the outer reflector 1 in this Height corresponds, i.e. is 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, causing possible glare can be avoided and at the same time a more uniform illumination is achieved.
- the diffuser 6 can also on the inside of the outer reflector 1 attached.
- the other components of the lamp serve primarily to supply energy to the two lamps or the holder of the lamp in the ceiling and are in their Radio instructions well known. It is therefore not intended to continue on them in the following To be received.
- the main component responsible for the lighting effects is the partially translucent inner reflector 8, which is designed as a dichroic cold light reflector made of glass.
- the goblet-shaped glass cladding alternates with about 50 in a vacuum Reflected layers of titanium and silicon dioxide vaporized.
- the resulting Surface reflection is approximately 98%. That from the low-voltage halogen lamp 7 emitted light is therefore largely reflected by the inner reflector 8, while only a small proportion falls on the outer reflector 1.
- this type of vaporization allows the transmission of heat radiation without the use of Infrared filters and is designed so that only certain parts of the color spectrum can be passed through the inner reflector 8. This will make one Reduction in color temperature of the emitted light from 3800 K to approx. 2500 K. reached.
- the transmitted and reflected by the outer reflector 1 has light thus a slightly different color composition.
- the individual facets of the exterior Reflector 1 then serve to further color reflections into individual light points disassemble, which increases the brilliance.
- Fig. 2a only the fluorescent lamps 3 are switched on, while the low-voltage halogen lamp 7 is switched off.
- the light emitted by the fluorescent lamps 3 passes through the diffuser 6 and leaves the lamp, here essentially three Light paths are conceivable.
- the light beam 11 leaves the lamp undeflected, while in the second case 13 at least by the outer reflector 1 is reflected once.
- the third possibility is that the beam 12 on the Outside of the inner reflector 8 hits, is reflected there and then the lamp leaves, of course he also at least one more time on the outer reflector 1 can hit.
- the low-voltage halogen lamp thus generates 7 and the inner reflector 8 a relatively intense but limited Light distribution with the color composition of the low-voltage halogen lamp 7, the inner reflector 8 appears from the outside in a slightly different color and the outer reflector 1 additionally reflects a weak amount of light.
- the third lighting option includes both the low-voltage halogen lamp 7 and the fluorescent lamps 3 turned on, resulting in a Superposition of the lighting effects described above results.
- the luminosity of the Fluorescent lamps 3 now outweigh the effect of the previously described the inner reflector 8 transmitting light rays 16b, so that a total widely spread and uniform room lighting 17 with the color characteristics of Fluorescent lamps 3, and a limited luminous cone 18 with the Color composition of the low-voltage halogen lamp 7 results.
- the choice of the inner reflector 8 targeted the lighting effects with its reflection and transmission properties can be changed. For example, a higher one would be conceivable Select transmittance or use it to filter out certain color components.
- the inner reflector 8 itself could also be faceted on the inside and / or outside be constructed.
- the outer reflector 1 can be instead of being faceted also have a smooth surface, which then leads to further disassembly the light rays are eliminated.
- the fluorescent lamps and the Low voltage halogen lamp other types of lamps can be used.
