Definitions
- the invention is based on a reflector-carrying light unit according to the preamble of claim 1. It is in particular a reflector lamp or a lamp equipped with a reflector.
- the light source therein is in particular a high-pressure discharge lamp, but also an incandescent lamp is suitable for this purpose.
- the invention further relates to a structural unit for use in such a reflector-containing light unit.
- a light unit is known, with a concave reflector and a light source, which is designed as a high-pressure discharge lamp.
- a glare protection for the light source is mounted on a Burstschutzrohr surrounding the light source.
- the Berststoffrohr a circumferential dent, in which the helmet-shaped glare protection is anchored.
- a disadvantage of this mount is that the anti-burst tube must be elaborately pre-treated in order to provide the possibility of anchoring, and that the glare shield must be equipped with an extra mechanism for anchoring.
- the glare shield is a sheet which is slipped over the bursting protective tube, wherein the glare protection consists of a hemispherical end part with a given maximum diameter, which is formed a straight cylindrical section with a larger diameter, this in turn a projecting screen is attached.
- the diameter of the cylindrical section is preferably 5 to 20% greater than the maximum diameter of the end part.
- the connection between the two parts is produced in particular by a stepped shoulder.
- the reflector-side edge of the Berstschutzrohrs is advantageously thickened drop-shaped, which is in particular possible in a simple way by flame rounding borrowed, the reflector-side end of Berstterrorismrohrs is adapted to the diameter of the cylindrical portion from the inside, so that the anti-glare with the step as a stopper clamping sits the Burststoffrohr.
- the light unit has a pedestal that supports the light source.
- the base can also hold the anti-burst tube and possibly the reflector.
- a particularly simple mounting would be the case if the bursting protection tube is also thickened drop-shaped on its base-side edge and thus can be clamped by the reflector neck, in particular by a suitably shaped bead or groove.
- the deformation of the reflector neck must generally be just above the drop. Instead of a drop can act as a holding means and a bore into which the reflector neck is fixed, for example by crimping.
- the light unit is in particular a reflector lamp or a reflector lamp.
- a typical power range is 20 to 150 W.
- a glare protection cap is additionally assigned to the light source next to a protective tube, which in particular conveys an anti-burst protection.
- An application is also possible incandescent.
- the anti-glare cap is placed over the light source to avoid glare in the reflector.
- the protective tube is made of vitreous material and consists in particular of tempered glass or quartz glass. It is a cylindrical tube that is open on two sides.
- the invention achieves a simple mechanical fixation of the glare protection on the burst protection tube.
- the glare shield is preferably, but not necessarily, a metallic sheet. It can also be made of high temperature resistant plastic or polymer ceramic.
- polymer-ceramic means a ceramic made of material, which is also referred to as polymer-ceramic composite or polymer-matrix composite material or polymer-ceramic composite. In this case, the composite material may be inorganic, organic or a mixture of organic and inorganic components.
- Such substances are known per se, for example, from the literature such as the textbook materials, Springerverlag, ISBN 3540573259 known.
- Known materials are, for example, carbide and nitride materials of inorganic polymers.
- the thermal stability of silicon carbonitride ceramics is very high.
- the wall thickness of the antiglare material is about 0.2 to 1, 5 mm, in the case of sheet metal it is rather thinner, in the case of other materials rather thicker.
- the anti-glare cap has such a geometry and is fixed to the Berstschutzrohr that it is not possible for the viewer to see the luminous center of the light source directly.
- the glare shield can be made of one part, preferably it is a deep-drawn sheet metal, but also a deeply pressed sheet metal is possible, in the case of non-metallic materials it can be sprayed (plastic or polymer ceramic).
- the glare protection can also be constructed in several parts. The parts may be welded together, but also crimped, bent, clipped or overmoulded.
- the geometry of the glare shield is chosen so that after placing the glare shield on the Berstschutzrohr the luminous part, such as the discharge vessel, is no longer visible.
- anti-burst tube means not only, but preferably, protection against bursting of the discharge vessel or innermost piston. There should be no hot ingredients escape from the protective tube.
- the upper opening edge of the protective tube is formed by flame rounding or else a bead or flange attachment.
- the increase in diameter in the north is supposed to be 5 to 10% and should not exceed 20%.
- the protective piston can also be fastened in a form-fitting manner in the base area, for example by kitten.
- snap-in connections in particular resilient elements, are provided in the cap, which cause a snap-in during joining over the bead or flange of the protective tube and thus prevent it from falling off, even in the case of greater shock.
- this elongated beads which are evenly distributed around the circumference of the cylindrical portion around and are matched with the drop-shaped thickening just so that the drop can just snap into the chamber between the step and the upper end of the bead.
- the locking connection can also have resilient elements or show other geometry.
- An example are notched tabs with different shape for snapping the flame-rounded glass thickening or separately mounted spring tongues.
- the flame rounding is generated with the flame of a gas burner. It can produce a rounded droplet that forms due to the surface tension. But it can also be applied to the mold after heating by the flame, as long as the heated edge is still sufficiently warm. It is recommended that in each case to rotate the tube to be deformed.
- the technique of flame rounding is known per se but unfolds in connection with the combination protective tube / visor cap a high saving potential.
- a second embodiment is a non-cantilevered construction.
- the anti-glare cap is essentially shaped as well, but without a step and with a constant diameter. Also any terminal chambers omitted.
- For fixing here serves a clamp, designed as a wire or sheet, preferably made of spring steel with a round or rectangular cross-section.
- a wire has advantageously 1 to 3 mm in diameter.
- the clamp is placed over the cap attached to the protective tube. The free ends of the clamp are locked in associated recesses, such as slots or holes in the reflector.
- the clamp is advantageously on the cover of the visor cap, which is advantageously flat, in a recess, recess or bead, out and so improves the fixation.
- the recess may in particular contain an eyelet as a covered channel, whereby the clamp can not be separated from the anti-glare cap after its threading into the eyelet.
- the connection of the clamp to the reflector can be done either by positive locking (bending the ends, especially in wire) or by adhesion, in particular support by pure spring force of the bracket or by friction).
- the protective piston is indirectly also fixed non-positively in this way.
- One field of application is in particular reflector lamps based on metal halide lamps, which are particularly compact.

- the diameter of the cylindrical portion 20 is about 10% larger than the maximum diameter of the hemispherical end part.
- At the base end of the cylindrical portion an obliquely projecting brim 21 is formed.
- the step 22 between end portion 23 and cylindrical portion 20 serves as a stop for the reflector-side end of the Berstschutzrohrs.
- the edge of the Berstschutzrohrs 6 is also flame rounded, so that the cylindrical portion is clamped against the thickening 11a of the edge.
- Figure 1b shows a detail of the positive and non-positive connection between the opening-side drop-shaped thickening 11a of Berststoffrohrs 6 and the cap 12, which is seated on the opening 10 of the reflector facing the Berststoffrohrs 6.
- the cylindrical section 26 is uniformly provided with corrugations 27 arranged axially parallel to its circumference. Their reflector-side end is chosen so that the teardrop-shaped thickening 11a just snaps into the chamber between step 22 and the end of the bead resiliently.
- the anti-glare shield 30 is designed so that the cap 31 is cup-shaped, with a flat lid 32 and a straight side wall 33.
- the movement takes place by means of a clamping strap 34 which is stretched over the cover 32 or other parts of the cap and which stretches from an opening 35 in the contour 36 of the reflector to a further opening 35b on the opposite side of the contour.
- the bracket 34 is a wire with a diameter of typically 0.5 to 2 mm.
- the lid 32 preferably has a guide of the bracket, for example a continuous dent 36, see the sectional drawing of the antiglare according to Figure 3c.
