Lamp cap The lamps must be manufactured with the lamp cap determined for the corresponding lamp type. The dimensions and tolerances of lamp cap are determined in DIN-s

22、heets. The DIN-sheet valid for the lamp cap is stated in the table 11.1. As material for the lamp cap brass, nickel-plated brass, stainless steel of quality X6 CrMo 17, material No. 14 113 to DIN 17 440 or polyamide PA 6.6(EDS-M-5101-21 or similar to unaffected by other materials requires a special

The form of soldering bead on the socket may not impair the perfect insertion of lamp into the lamp socket. The maximum diameter of

25、lamp cap may be exceeded around maximum 1mm by the lateral soldering bead. The end of lead may not protrude from the soldering bead. The socket leads may not form any internal short-circuit and may not be interchanged with 2 radiant bodies at bulbs. 7.1.5. Connection glass bulb-lamp cap The connecti

26、on between glass bulb and lamp cap must be performed, so that the positioning of annealing coil corresponds to the specified dimensions and tolerance in proportion to the socket and doesnt experience any changes during the operating time. The minimum value for the strength of connection of glass bul

This limiting value may not be fallen short of after a condensed water-climate test to EDS-T-7005 -D2-. 7.2. Mechanical requirements 7.2.1. Dimensions The geometric

28、 shapes of radiant bodies of bulbs represented in the respective standard sheets are to be observed. The position of radiant bodies is measured at connected lamp at 90% to 100% of test voltage. Start and end of a straight radiant body are determined on the helical figures in a parallel projection ve

29、rtical to the reference axle and is the result, if nothing else is determined, of the position of vertex of the first and the last full-formed helical motion in the image plane vertical to the direction of projection(at wound coils the vertex of the secondary coil is to be taken). For the determinat

30、ion of dimension in the image plane the dimension line is laid radiant bodies and parallel to this at transversal lamps. For evaluation only the vertexes are applied, which belong to (light) luminous helical motions, and at which the figures of outgoing helical parts form an angle of maximum 90to ea

Compressive strength of glass bulb The test is performed between 2 plane steel plates which have a 2mm thick coating of VMQ-elastomer 60 IRHD. The one plate is fixed and the other one moves with a speed of stress of 3mm/min. The force is reg

Torsional strength of connection of glass bulb and lamp cap. For the test the lamp cap is inserted into a special lamp socket

34、or kept in a boring socket. Over the bulb a suitable cone is shifted which has inside a coating of 2mm thick NR-elastomer(60 IRHD). The torsion of a holder is performed with a speed of 2 / min. The torque is measured, until the socket cementing no more stop. This torque must lie over the minimum val

At bulbs with 2 radiant bodies both radiant bodies must be aged independent of each other(low beam body first). Air drawers are not valued. 7.3.2. Power

38、input After the one-hour aging the power input of the bulb is determined from the measurement of current and voltage, at which the voltage is tapped directly at the measuring socket(separate contact pairs for current and voltage). If necessary internal consumption of voltmeter is to be drawn off fro

39、m the current indicated on the ammeter. The output values specified for the different lamp types are to be taken from the table 11.3. 7.3.3. Photometry The measurement of luminous-flux of the bulbs is performed with the Ulbricht sphere-type photometer according to the method specified in DIN 5032, p
