Definitions
- the invention relates to a lamp housing unit according to the preamble of patent claim 1.
- Such lamp housing units are used in video projectors (both front projectors and rear projectors).
- the lamp housing unit can hereby as
- Lamp can be replaced with a new lamp, the lamp housing unit can be removed again. As a result, the correct adjustment of the lamp is simplified.
- the object of the present invention is to provide a LAM pengepuriser according to the preamble of the patent applica ⁇ claim 1. which is adjustable forth ⁇ inexpensively as possible, and is fanned in the agreed a change of the lamp.
- a sheet metal strip fixed ⁇ arranged in the lamp housing which extends into the interior and is thereby connected to a lamp to be used as Stromlei ⁇ tion to can.
- a sheet-metal strip As a power line, where ⁇ preferably provided for forward and return of the stream each a metal strip, connections can be made directly to the sheet metal strip itself, so there must be no connection means such as connectors on the Blechstrei ⁇ fen provided, so that There are no relevant manufacturing steps in this regard.
- a Blechstrei ⁇ fen a certain rigidity. This requires that the metal strip end is more or less at a predetermined location in the interior of the lamp housing. With a suitable choice of this location, the sheet metal strip must not be bent or at least not strong when a lamp is to be connected. The lamp fitter therefore, it does not have to worry about positioning the metal strip.
- the sheet metal strip may have a deviating from a straight line shape, so have at least one bending or bending point, by which it is preformed, in the current direction.
- the metal strip may have a rectangular cross-sectional profile as conventional metal strips and thus already has a good stability. To increase the stability ⁇ formality but it has proven to be useful to give a cross-sectional profile with a non ⁇ rectangular shape the sheet metal strip.
- a metal strip having a rectangular cross-sectional profile and the non-rectangular shape can be achieved by press-forming, for. B. by the sheet metal strip is bent in the cross-sectional profile, for example by an angle greater than 45 ° and preferably at an angle of about 90 ° (between 85 ° and 95 °).
- Such a press ⁇ shaped sheet metal strip is particularly rigid and therefore stable, and mounting the lamp is particularly kar ⁇ facht.
- High-pressure discharge lamps are driven by an electronic ballast.
- a relatively high ignition voltage must be generated.
- a printed circuit board with the electronic components for generating an ignition voltage can be attached to the lamp housing.
- the metal strips are provided. In this case, it makes sense if the ignition voltage between 1.8 and 3.2 kV, preferably between 2 and 3 kV.
- the metal strips are provided. In this case, it makes sense if the ignition voltage between 1.8 and 3.2 kV, preferably between 2 and 3 kV.
- the metal strips At a higher ignition voltage, it would be necessary to separate the metal strips by an insulating material, so that no spark can jump. With the stated voltages of 2 to 3 kV, the air gap which is usually available in a lamp housing interior is sufficient.
- connection connections wherein the connections out ⁇ se ⁇ sets for a voltage of 300 to 400 V may be provided for coupling an electronic ballast now again be need.
- These lamp connections can be designed as a screw connection, plug connection, solder connection or can be welded or crimped. It is also possible to provide connection contacts as a contact spring which can be connected directly to a contact surface on the electronic ballast.
- the lamp housing unit carries the printed circuit board with the electronic components for generating an ignition voltage
- it can also be provided that it can be indirectly connected to an electronic ballast, which then converts the electronics for generating an ignition voltage - sums up.
- an electronic ballast which then converts the electronics for generating an ignition voltage - sums up.
- the connection element can be provided as a screwable, pluggable, solderable, weldable or crimpable contact or as contact with a contact spring.
- the sheet metal strips can be an eyelet or a fork aufwei ⁇ sen, crimpable, solderable, pluggable or weldable when manufactured in conjunction with the lamp.
- the invention also includes a video projection device with an inventive lamp housing unit insbesonde ⁇ re a removable unit.
- FIG. 1 shows in section a lamp housing unit according to a first embodiment of the invention
- FIG. 4 the connection of a sheet metal strip with a printed circuit board
- Fig. 5 in section a lamp housing unit according to a second embodiment of the invention.
- a generally designated 10 lamp housing unit (Fig. 1) has walls 12, 12 ', z. B. plastic, which form the actual lamp housing and an inner space ⁇ 14 surrounded, in which a high-pressure discharge lamp 16 is receivable.
- the lamp 16 is suit ⁇ supported by a metal sheet 18.
- the lamp housing unit 10 is characterized in that it is already equipped with the electronics by which an ignition voltage for the high-pressure discharge lamp 16 of between 2 and 3 kV can be generated.
- On a printed circuit board 20 corresponding electronic components 22a, 22b, 22c, 22d are arranged.
- the conductor ⁇ plate 20 itself is held laterally in guides 24. It must now be transferred from the circuit board 20, the clamping ⁇ voltage to the lamp 16. For this purpose, 20 metal strips 26, 26 'attached to the circuit board.
- the sheet metal strip 26 has a circular recess, through which a lamp with a first electrode of the lamps not shown in the figure - Burner connected terminal pin 28 of the lamp 16 is feasible, wherein this has a thread, via which a nut 30 is screwed to secure the sheet metal strip 26 to the lamp 16.
- the metal strip 26 ' also has at its end a bore through which a Bolt 32 is feasible, which allows a connection of the sheet metal strip 26 'on a side wall 34 of the lamp 16, on which a metal bushing is inquirege ⁇ provides, which is connected to a second electrode of the lamp burner.
- connection element or con- tact 36 is shown to which is screwed ⁇ a counter-contact element or may be infected.
- the Anschlußele ⁇ element 36 may also be designed to be solderable, weldable or crimpable.
- sheet metal strips 38, 38' are provided which have a non-rectangular cross section. Rather, these sheet metal strips, for example, the cross ⁇ shown in Fig. 3A was given 38 or 38 'is a cross-sectional profile through press-forming, sectional profile.
- the metal strips may also have the profiles of FIGS. 3B, 3C and 3D, respectively. The profile can thus be angled, have an L-shape or have a U-shape or, as in FIG. 3B, have a bulge. These profiles ensure a particularly high stability of the metal strips 38, 38 '.
- connection elements 36 are provided on the circuit board 20.
- a second embodiment 10 '' of the lamp housing unit the electronics for generating the ignition voltage is not integrated into the lamp housing unit.
- sheet metal strip 44 or 44 ' which are shown in Fig. 5 in a profiled shape as shown in Fig. 2 (profiles according to Figs. 3A to 3D), di ⁇ rectly on a housing wall 12' attached ', and it is di ⁇ directly to the in the housing wall 12 '' attached sheet metal strips 44 and 44 'connecting elements 46 and 46' provided. These may have the same properties as described above for the connection elements 36.
- the lamp housing unit 10 '' should be coupled to an electronic ballast, in which a ⁇ electronics for generating an ignition voltage is provided.
- the starting voltage should not be less than ⁇ 3 kV.
- the air gap between the metal strips 26, 26' or 38, 38 'or 44, 44' is sufficient so that no sparks are ignited at an ignition voltage of 3 kV. At higher voltages, the air gap may not be sufficient.
- the lamp housing units 10, 10 'and 10'' are to be installed in a video projection device and its ent ⁇ Neillbar again.
- the lamp 16 can be easily replaced without having to handle the entire video projec- tion device.
