Definitions
- the invention relates to a light source, in particular a fluorescent lamp, with at least one lamp vessel.
- pigment sublayers As color filters between the lamp vessel and the phosphor layer.
- These pigment sublayers absorb the unwanted components in the light spectrum of the lamp such that the desired color locus, for example a yellow color locus in NiSbTiO.sub.2 pigments or a red color locus when using Fe.sub.2O.sub.3 pigments, is used.
- Pigments is achieved.
- a disadvantage of such light sources is, on the one hand, that the pigment underlayer absorbs a large part of the optical radiation and thereby reduces the efficiency of the fluorescent lamp and, on the other hand, the coating process for producing the pigment underlayer is complicated and cost-intensive. It was also found that the filter effect of the pigment sublayers of such lamps often does not meet the high requirements for color saturation. Furthermore, it is disadvantageous that in the case of a rupture of the lamp vessel, a danger to persons due to splinters and particles is possible, which can be minimized only by a protective tube, which is applied to the lamp vessel in addition to the pigment sublayers and is known from the general state of the art. but again absorbs a portion of the optical radiation and thereby further reduces the efficiency of the fluorescent lamp.
- the invention has for its object to provide a light source in which over conventional solutions an efficient light emission with high color saturation and splinter protection with minimal device complexity is possible.
- a light source in particular a fluorescent lamp, with at least one lamp vessel, wherein a high temperature resistant silicone rubber is arranged on the lamp vessel, which is provided to produce a saturated light color with at least one light color and light saturation influencing pigment.
- the light source according to the invention allows luminous flux stability comparable with conventional three-band fluorescent lamps over the burning time. Such light sources are used for example in effect lighting for the production of color effects, as a stage and shop window decoration or party lighting. Furthermore, the lamps are advantageously used as component lamps in color-adaptive lighting tasks.
- the silicone rubber is advantageous in terms of manufacturing applied as a coating on the lamp vessel.
- a silicone resin can be used, which is applied to the lamp vessel and then cured.
- the pigment incorporated in the silicone rubber is an oxidic or nitridic pigment. - A -
- the silicone rubber hose is preferably applied to the lamp vessel such that an outer peripheral surface of the lamp vessel is substantially completely covered.
- an ionizable filling is included, which consists essentially of one or more noble gases and a small amount of mercury.
- a high temperature resistant silicone rubber 22 is arranged, which is provided to produce a saturated light color with at least one light color and light saturation affecting pigment.
- the pigmented silicone rubber 22 is formed as a prefabricated tube 24, axially slid onto the lamp vessel 2 and due to a slight undersize relative to the lamp vessel 2 attached to this non-positively. As a result, the silicone tube 24 is fixed to the lamp vessel 2 in a manner that is simple in terms of production technology.
- the light source according to the invention allows luminous flux stability comparable with conventional three-band fluorescent lamps over the burning time.
- the light source 1 of the invention is not limited to the illustrated rod-shaped lamp vessel 2, but the light source 1 may have different known from the prior art lamp vessel shapes, the lamp vessel 2 may be formed for example U-shaped or annular, in particular, the light source. 1 also be designed as a single-capped compact fluorescent lamp or light emitting diode. Since the light color and color saturation are determined by the type of pigments used, in addition to the light colors mentioned, all light colors which can be produced by means of pigments and are known from the prior art can be realized.
