Definitions

• the invention relates to an energy-saving lamp unit which has at least one gas discharge tube located in a glass bulb, a high-frequency ballast attached to the neck of the glass bulb, and a lamp base adjoining it.
• Such lamp units which are provided with at least one, expediently high-pressure gas discharge tube and to which the gas discharge tube containing G-gas bulb is fastened in some way to a ballast which is necessary for actuating the gas discharge tube .
• the ballast is equipped with the well-known threaded lamp base of the incandescent lamps, which is why this compact lamp unit can be screwed into the incandescent lamp holder without any special expertise. It is customary to call such a lamp unit an energy-saving lamp unit, since the high-pressure gas discharge tube consumes one-fourth to one-third less energy than the incandescent lamp at the same light intensity.
• Such a lamp unit announces the description of the Hungarian patent application under No. 1226/81.
• Attaching the ballast to the lamp bulb means a problem with the energy-saving lamp units. It is not possible to apply hot glue to the base of the incandescent lamps because the heat affects the semiconductor components - which are usually present in such ballasts.
• a solution is known according to which the electrodes of the gas discharge tube are bound to the power supply pins protruding from the lamp bulb and these are inserted into the resilient contact sockets mounted on the ballast.
• the disadvantage of this construction is that in the manufacture of incandescent lamps, the melting down of the lamp bulb has to be carried out using a more expensive method instead of the usual reliable and cheap glass technology.
• the ballast should be of smaller size, i.e. the lamp unit should not differ in geometric sizes from the incandescent lamp, in whose place it is to be used.
• the 50 - 60 Hz mains current is converted into a high-frequency current because the current-limiting choke coil of the gas discharge tube can have a smaller geometric size, since a lower inductance value is required proportionally to achieve the same impedance with increasing frequency.
• Such a high-frequency generator of the high-frequency ballast is expediently of an electronic design, and it must be fed by a rectifier.
• This set of rectifiers also contains an energy storage filter capacitor, which is one of the largest components of the geometric size of the high-frequency ballast and consequently its arrangement is problematic.
• One of the objectives of the invention is that the high-frequency ballast can be easily attached to the lamp bulb of common construction and design, its flexible power supply retained.
• the other objective is the appropriate arrangement of the energy storage filter capacitor, the gas length of the energy-saving lamps unit not increasing at all, or only of insignificant value, and the conventional melting technology of the lamp bulb also being retained.
• the first Zeilsetzurg is solved according to the invention with an inserted fitting, which is attached on the one hand by gluing to the neck of the lamp bulb, on the other hand, the fitting with a detachable or non-detachable connection to the high-frequency ballast, expediently plate on its base, which contains the electronic components carries, connected.
• the invention is on the one hand an energy-saving lamp unit, in the lamp bulb of which at least one gas discharge tube is arranged, is provided with a high-frequency ballast attached to the neck of the lamp bulb and is provided with the lamp base connected thereto, and also contains a shaped piece which, on the one hand, with adhesive - expediently heat-binding adhesive is attached to the neck of the lamp bulb, on the other hand is connected to the base plate of the high-frequency ballast, expediently to its base plate, with a detachable or non-detachable connection.
• the plate base of the glass frame known from the production of incandescent lamps is included in the neck of the lamp bulb.
• the detachable or non-detachable connection - depending on the material, design of the molded piece and the base plate - can be very diverse, but it is expedient to use a screw or rivet, or a soldered connection, or spot welding, or gluing.
• the invention is an energy-saving lamp unit, in the lamp bulb of which at least one discharge tube is arranged, is provided with a high-frequency ballast attached to the neck of the lamp bulb and with the lamp base connected thereto, and its energy storage filter capacitor extends into the cavity of the lamp base.
• the energy storage filter capacitor expediently takes up at least half of the lamp base cavity.
• FIG. 1 An example of the energy-saving lamp unit according to the invention is shown in FIG. 1, in which a gas discharge tube 5, a glass frame 2 are mounted on their holders 3 and 4 in a lamp bulb 1.
• the electronic components are arranged on a base plate 11 of a high-frequency ballast 8, but a coil body 17 is used to support the choke.
• Adhesive 6 binds a shaped piece 7 to the neck of the lamp bulb 1.
• the shaped piece 7 expediently has two threaded holes for fastening a base plate 11 with screws 10. Den Secure the spacing of the base plate spacer 9.
• An energy storage filter capacitor 12 is arranged on the base plate 11, but on its lower side located near a lamp oc ke ls 13, which is eight - nineteenth of the cavity of the lamp base 13 fills out.
