IEC 60598-1 Luminaries Adjustment Test Equipment Lamp Adjustment Torsion Device Rotation Angle 360°
 
Standard and Clause For Luminaries Adjustment Test Equipment:

 
This lighting adjustment test equipment matches the requirements of clause 4.14.3 of IEC 60598-1, mainly used for the lamp adjustment device’s torsion, and bending test of the table lamps, floor lamps and the lamps which are for professional use (such as a plotter lamps).
 
Product Information For Luminaries Adjustment Test Equipment:
 
a) Adjusting devices and means of adjustment, for example joints, hoisting devices, adjusting brackets or telescopic tubes, shall be so constructed that cords or cables are not pressed clamped, damaged or twisted along the longitudinal axis by more than 360° during operation.
If a luminaire has more than one joint the 360° limit applies to each joint if they are not too close together. Each case needs to be judged on its own merits.
Compliance is checked by the following test and inspection:
The adjusting device, equipped with the appropriate cable or cord shall be operated in accordance with Table 4.5. A cycle of operation is a movement from one extreme of the range to the other and back to the starting position. The rate of movement shall not causethe device to heat appreciably and shall not exceed 600 cycles per hour.
For electromechanical contact systems, this test is conducted simultaneously with theelectrical connection test of 4.11.6.
During the test the values according to Table 5.2 shall not be exceeded.
After the test, not more than 50 % of the strands in a conductor shall be broken nor shall there be any serious damage to the insulation, if any, of the flexible cord. The cord or cable shall be subjected to, and shall satisfy, the insulation resistance and high-voltagetests specified in Section 10.
Ball-joints and the like, where the clamping means can be adjusted, are tested with the joints only lightly clamped to avoid excessive friction. lf necessary, the clamping areas arereadiusted during the test.
For adjusting devices that consist of a flexible tube, the range of adjustment for this test is normally 135° in both directions from the vertical. However, where this adjustment cannot be achieved without using unreasonable force, the flexible tube is bent only to the positions where it will remain by itself.
b) Luminaires with a means of adjustment intended to be installed within arm's reach, shall allow the operation of its intended function without impairing the stability of the luminaire or causing deformation of any part of the construction, nor cause injury due totemperatures above those specified in Table 12.1.
Compliance is checked by manipulating or handling the luminaire, by the means of adjustment as expected to represent normal use and by measurement of the temperaturesduring the test of 12.4
c) For luminaires intended to be mounted within arm's reach, the space surrounding anymeans of adjustment, except the light beam aperture, up to 5 cm away irom the means of adjustment in any direction, shall comply with the temperature limits for the means ofadjustment, as specified in Table 12.1. The same temperature limits apply also to anymeans of adjustment which are lit after the positioning of the luminaire light beam aperture.
