Definitions
- the invention relates to a low-pressure discharge lamp with a base on one side according to the preamble of claim 1 and an associated version according to the preamble of claim 9.
- Such lamps are characterized by their rather flat shape.
- a tubular discharge vessel with a typical circular cross-section arranged in a plane so that the two ends of the discharge vessel face each other.
- the ring shape is particularly common. Because of the associated circular symmetrical radiation pattern it is particularly suitable for general lighting, e.g. in residential and office space.
- the lamp is usually in one Luminaire installed, which may also include an optical reflector for light control can include.
- the power supplies are inside electrodes arranged in the vessel are guided gas-tight to the outside.
- the two ends of the vessel are supplied with power from one common elongated base surround.
- the power supplies are with electrical contacts of the base connected.
- the base contacts serve the contact with the corresponding contacts of a lamp holder.
- An annular fluorescent lamp is known (e.g. OSRAM L32 / 41-827C with base G10q), in which the pin-shaped base contacts at an angle 45 ° square with respect to the ring plane of the lamp are.
- a lamp which corresponds to the preamble of claim 1 is known from CH-A-270 390.
- the object of the invention is to eliminate the deficiencies mentioned and a low-pressure discharge lamp of the type explained at the beginning Specify a compact, flat and simply designed Has base, the simple and quick lamp assembly and, if necessary Equipping a lamp enables.
- Another object of the invention is one according to the invention Specify socket associated version.
- the basic idea of the invention is that the base contacts are essentially in to be arranged in the plane in which the discharge vessel extends, the half of the socket contacts on a first side of the socket and the other Half are arranged on the opposite side of the base.
- the two base contacts of each lamp end are preferably open the opposite sides of the base. Thereby can use the power leads to connect to the base contacts be kept short. It can also prevent that the power leads in the base touch.
- the base according to the invention is particularly small Overall height.
- This base with discharge tubes is particularly advantageous with particularly small diameters (typically 16 mm instead of the previously usual 30 mm) is used. This has the advantage that the entire arrangement of lamp with base is relatively flat.
- the associated version has a channel-like opening for receiving the Base on.
- the two side walls of the opening are each with two provided slot-like recesses for receiving the base contacts.
- In contacts are arranged in the cutouts.
- the base according to the invention has a elongated, cylinder-like basic shape that is open on both ends on.
- the circular openings in the base accommodate the two Ends of the discharge vessel including the associated power supplies.
- Two pin-shaped contacts each protrude from the base.
- the power supply lines are preferred in the common Level of the base contacts from the discharge vessel to the outside guided. In this way, a particularly flat design can be achieved, without the power supply lines touching each other.
- the associated version has a U-shape-like basic shape.
- the two Legs of the socket each have two slot-like recesses Contacts. They serve the establishment and contact with the appropriate Base contacts. To do this, the lamp base is placed in the space between the thighs used.
- the socket contacts are as detent springs educated.
- the socket contacts snap into place when the base is inserted into the socket into the socket contacts.
- the socket contacts serve not only for electrical contact making but also to lock the base and consequently the one connected to the base Lamp in the socket.
- the locking is by additional fastener taken over.
- the two side walls the channel-like opening, each with a nose-like retaining spring provided that when connecting base and socket in corresponding Snap the recesses into the outer wall of the base.
- the fluorescent lamp 1 shows the top view of a fluorescent lamp 1 according to the invention shown schematically.
- the fluorescent lamp 1 is known per se Way of an annular discharge tube coated with a phosphor 2, in which two glow electrodes are arranged (not shown) and a base 3 with four pin-shaped base contacts (8a, 8b, 9a, 9b), in whose circular cylinder-like extensions 4,5 the two ends of the discharge tube Protrude 2.
- the discharge tube 2 has a circular shape Cross section with a diameter of approx. 16 mm.
- the base represents the actual innovation of the lamp and is therefore closer to the following explained.
- the same reference numerals designate the same features.
- FIGs 2a to 2c show the top, side and end view of the base 3 of the fluorescent lamp 1 from Figure 1.
- the base 3 consists of a elongated, cuboid middle part 6 and the two circular cylinder-like Processes 4,5.
- the extensions 4,5 are each on the two end faces of the middle part 6 formed obliquely around, as indicated in Figure 1, the two To be able to accommodate ends of the annular discharge tube 2.
- Out two opposite side walls 7a, b of the central part 6 each protrude two contact pins 8a, 9a and 8b, 9b.
- Two contacts 8a, 8b each form or 9a, 9b - a contact from each of the two opposite side walls 7a, 7b - a pair of contacts.
- the first pair of contacts 8a, 8b is with the two Power supply lines of the first end of the discharge vessel 2 connected (not shown) and the other pair of contacts 9a, 9b with the power supplies of the other end (not shown).
- the mentioned side walls 7a, b each have two rectangular recesses 10a, 10b or 10c, 10d (the recess 10d is covered in the illustration), wherein each pair of recesses 10a, 10b and 10c, 10d opposite each other in Area of the longitudinal edges is arranged.
- One recess 10a, 10c per side wall serves as a snap-in opening for corresponding retaining springs of the associated Frame.
- the respective other recess 10b, 10d serves accordingly Base of the locking device turned by 180 °.
- the longitudinal edges of the middle part 6 are provided with chamfers 11 for tilting when inserted into the Avoid lamp holder.
- Figures 3a and 3b show the top view and end view of a Base from version 1 belonging to Figure 1. It has a channel-like shape with a rectangular base and a U-shaped front view.
- the both legs 13a, 13b of the socket each have two slot-like recesses 14a, 15a and 14b, 15b with spring contacts 16a, 17a and 16b, 17b on. They serve the establishment and contact with the appropriate Pin contacts 8a, 9a and 8b, 9b of the base 3.
- the two side walls of the channel-like opening between the legs 13a, 13b are each with one provided nose-like retaining spring 18a, b.
- the lamp base 3 is inserted into the channel-like opening (not shown).
- the retaining springs 18a, b of the socket snap into place the recesses 10a, 10b of the base 3.
