Characterization of bulbs The bulbs must carry following inscriptions(stamp values) on the lamp socket, or if the action
15、 of bulb is not inadmissibly impaired by this, on the glass bulb: Manufacturer mark Official test certificate of approval of type(so far as necessary) Nominal voltage in V Nominal power in W These details must be well-legibly and durably labeled. 7.1.2. Inner structure of bulb The inner structure of
16、 bulb with annealing coil and coil holder must be so designed that the positioning of annealing coil and of, if necessary, available cathode screens corresponds to the specified dimensions and tolerances and doesnt experience any changes during the working time. The annealing coil out to tungsten wi

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
23、approval. The lamp cap must be so provided that it resists the normal actual service conditions without deformation. At the lamp types R2 and H4 the connection between adjusting plate and lamp cap must resist a force of minimum 400N applied axially, arranged in assembly direction of plug without dam
24、age. The fixing pin(n) of plate may not be bent at that time. The current supply to the annealing coil(socket lead) must be firmly soldered and welded with the socket. 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
27、b and lamp cap at delivery and after the life test is specified in the table 11.2 for the respective lamp types(test see clause 7.2.3). 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
31、ch other. At axial radiant bodies the utmost possible position of respective vertex is to be determined by turning the lamp, at transversal radiant bodies the radiant body is laid vertical to the direction of projection EDS-T-5242MOTOR VEHICLE BULB PAGE: 5/11 ISSUED DATE: 1995. 03. 14 REVISED DATE:

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
33、istered, at which the glass bulb breaks. The minimum compressive force, which the glass bulb must endure, is specified in the table 11.2 as bulb compressive strength. 7.2.3. 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
35、ue of strength of the socket cementing specified in the table 11.2. 7.2.4. Plug drawoff force At the 12V 55W H3-bulb the drawoff force for the plug after opening the strain-relief shall amount 120N. 7.2.5.

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
40、art 1 at test voltage at the measuring socket. The measurement is performed after the one-hour aging and besides after reaching the 75% of average life. The values of luminous-flux specified for the different lamp types and the permissible percentage decrease of luminous-flux of an individual lamp o
41、r of an annealing coil after reaching the 75% of average life are specified in the table 11.3.
