Definitions
- the invention relates to a compact low-pressure discharge lamp from a discharge vessel with electrodes and power supplies and a cap, housing and mounting plate with ballast arrangement composite base, the mounting plate with the ballast assembly is attached inside the base housing and connections for the electrical connection of the power supply lines to the mounting plate having.
- Known low-pressure discharge lamps are increasingly replacing them Incandescent lamp in the house and living area.
- the discharge vessel usually consists of a single or multiply bent tube, which is arranged in a base.
- the base In the base is a mounting plate designed as a circuit board with a electronic ballast assembly soldered to it integrated.
- the manufacturing cost for these compact low pressure discharge lamps are relative high, since many complicated manufacturing steps are required in the manufacture are.
- One of these manufacturing steps is the electrical connection the power supply lines of the discharge vessel with the corresponding connections the ballast arrangement. To make this connection previously merged the corresponding connecting wires and for example crimped with a metal sleeve.
- EP-A-0 452,743 discloses a low pressure discharge lamp of the type described above, which has retaining pins with whose help the ends of the power leads perpendicular to the bow-shaped Leads of the ballast are aligned.
- the respective wires to be contacted are approximately at right angles arranged one behind the other and with the help of the retaining pin and the inner wall of the base housing resiliently pressed against each other, so that an electrical Connection between the electrodes of the discharge vessel Ballast arrangement is made.
- a compact low-pressure discharge lamp the power supply lines of a discharge vessel with the electrical connections a mounting plate with ballast arrangement via a spring element, which pushes the power supply connected to the connector.
- a spring element which pressure on the power supply exerts a secure contact is guaranteed.
- advantageously only one element is used for the connection the power supply lines of the discharge vessel with the corresponding ones Connections to the mounting plate or the ballast required. This significantly reduces the manufacturing costs. It also results this advantageously results in a significant increase in the production speed, because when assembling the base of the low pressure discharge lamp Base housing and base cap just pressed together Need to become.
- the spring element Before assembling the base, the spring element is inventively received in a spring receptacle formed on the inner circumference of the cap.
- the spring receptacle has a cavity for receiving it from at least part of the spring element and is usually rectangular in cross section. This allows the spring elements regardless of the final assembly of the lamp, resulting in a Simplification of the manufacturing process contributes and thus the manufacturing costs lowers.
- the low-pressure discharge lamp according to the invention is a shoulder in the cavity of the spring holder designed to support an area of the spring element.
- a shoulder in the cavity of the spring holder designed to support an area of the spring element.
- the inner circumference of the housing and the outer circumference of the Cap formed a gap for receiving one end of the power supply.
- these features also contribute to simplifying the manufacturing process the lamp.
- the mounting plate perpendicular to the lamp's longitudinal axis attached inside the case.
- the mounting plate is there on ribs formed on the inner circumference of the housing, which are parallel to Lamp longitudinal axis run on.
- the mounting plate is advantageous formed as a circuit board, the one facing the discharge vessel Conductor side and on the side facing away from the discharge vessel Circuit elements of the ballast arrangement are formed. It is at least one connection for electrical contacting of the power supply trained with the mounting plate as a pad.
- In another advantageous Training has at least one connection to electrical Contacting the power supply with the mounting plate from one or several flat soldering areas and / or strips.
- FIG. 1 and Figure 2 is a schematically shown sectional view of a Compact low-pressure discharge lamp 10 according to the invention or one Portion of the edge region of the base 12 reproduced.
- the lamp 10 includes a discharge vessel 14 and a base 12, the base 12 is composed of a cap 16 and a housing 18.
- the base 12 is essentially cylindrical.

- the cap 16 has the Housing 18 facing end of an annular bead 20 in its outer periphery on.
- the bead 20 and an annular groove 22 in the inner circumference of the housing 18 form a gap 34 for receiving an end 32 of a power supply 30 out.
- the mounting plate 24 is designed as a circuit board, on which the discharge vessel 14 facing conductor tracks and on the discharge vessel 14 opposite side circuit elements of the ballast arrangement (not shown) are trained.
- the discharge vessel 14 usually consists of two or three U-shaped bent pipe sections, which are connected to each other by a passage are (not shown), the end legs each carrying electrodes.
- the free ends of the pipe sections are sealed gas-tight by crushing and sit inside the cap 16 of the base 12.
- the current leads 30 are against the by means of a spring element 28 electrical connections 26 of the mounting plate 24 pressed.
- the spring element 28 engages in a formed in the region of the inner circumference of the cap 16
- Spring receptacle 40 and is in the embodiment shown detachably fastened in it.
- the spring receptacle 40 consists of side walls 41, 43, which surround a cavity 42.
- the cavity 42 is used for receiving a part of the spring element 28 and is rectangular in cross section educated.
- a shoulder 44 for supporting an area 50 of the Spring element 28 formed.
- the side walls surrounding cavity 42 41, 43 point towards the free end of the spring receptacle 40 46 on. These bevels 46 facilitate the introduction of the spring element 28.
- Gap 34 placed and thus aligned in the correct position.
- the mounting plate 24 has on the discharge vessel 14 facing Page connections 26 for electrical contacting of the power supplies 30 of the ballast arrangement.
- the connections 26 can be used as a pad or also as flat soldering surfaces integrated or resting in the mounting plate 24 and / or strips.
- FIG. 2 shows a sectional view of a partial area of the edge area of the Base 12. It can be seen that the free end of the housing 18 with the free End of the cap 16 is connected. In the area of the inner circumference of the cap 16, the spring holder 40 is formed. Surround the side walls 41, 43 the cavity 42 in the on the facing in the outer periphery of the cap 16 Page the shoulder 44 is formed. The spring holder 40 is in the Cross-section essentially rectangular. You can also see the bevel 46 of the side walls 41, 43. Also the different overall lengths the two side walls 41, 43 are clearly visible.
- a circumferential tab 36 forms the end of the cap 16 in the direction the mounting plate 24.
- the tab 36 forms at predetermined locations thorn-like extensions 37, which in corresponding recesses 38 of the Engage mounting plate 24.
- the thorn-like extensions 37 of the tab 36 and the recesses 38 thus form the positioning device 48.
- FIG. 3 shows a top view of a part of the edge area of the base 12 of FIG Lamp 10. It can be seen that the ends 32 of the power leads 30 in the between the circumferential tab 36 and the inner circumference of the housing 18 formed gap 34 comes to rest.
- the Power supply lines 30 below the spring element 28 are on the outer circumference the cap 16 in the area of the spring receptacles 40 each recesses 52 designed to receive the ends 32 of the power supply lines 30.
- Figure 4 shows a schematic representation of the design of the spring element 28.
- the spring element 28 is a multi-curved spring steel strip shown.
- the length of the spring element 28 is chosen such that that a reliable contact between the power supply 30 and the Connection 26 of the mounting plate 24 is guaranteed.
- the spring element 28 consists of plastic and / or metal and / or a metal alloy.
- the spring element can in a further embodiment, not shown be designed as a spiral spring. Any other advantageous feather shape is conceivable.
