Problems solved by technology

However, if the ballast is operated at high temperature for a long time, the insulating varnish on the coil of the ballast will gradually carbonize over time, and the insulation performance will gradually decrease.
As a result, part of the coil leakage will cause a short circuit between turns or layers of the coil, the impedance of the ballast will decrease, and the current of the lighting system will increase, which may eventually cause the ballast, trigger, light source or terminal of the ballast to burn out. bad, and may even cause a safety accident

Abstract

The embodiment of the invention discloses a method for testing reliability of a lamp. The method includes: measuring the inductance of a ballast when the lamp works normally; calculating to obtain a first current of the ballast when the inductance of the ballast is reduced by a first percent of a threshold value; and inputting the first current to the ballast, and detecting the working condition of the lamp in a first preset time. Correspondingly, the embodiment of the invention also discloses a device for testing reliability of the lamp. By adoption of the method and device for testing reliability of the lamp, influence of a change of the inductance of the ballast on the lamp can be tested, thereby improving safety and stability in use of the lamp including the ballast.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a method and device for testing the reliability of lamps. Background technique [0002] The safety and stability of lamps are very important and have a very important impact on people's daily life and work. In the field of industrial lighting, the current industrial lighting sources mainly use high-pressure gas discharge lamps. Among them, the ballast is an indispensable component when the high-pressure gas discharge lamp works, because the self-inductance of the ballast can stabilize the current in the circuit. The role, so as to ensure the stable work of lamps and lanterns. The life of the ballast directly affects the life of the lamp as a whole. Therefore, when developing new products, it is necessary to verify whether the quality of the ballast of the lamp meets a certain temperature requirement. For example, the ballast tw is marked as 130, which means that when the coil temper...
