When using led track lights, try not to switch frequently, because the current through the filament is higher than the current during normal operation, so that the temperature of the filament rises sharply and accelerates sublimation, which will greatly reduce its service life. Therefore, it is necessary to minimize the switch of the led track light fixture. During cleaning and maintenance, care should be taken not to change the structure of the luminaire, and do not replace some of the components inside the led track light fixture. After the cleaning and maintenance is finished, the luminaire should be installed as it is, without missing or misplaced lamps and components; The light source parameters provided by the mark replace the aging lamp in time, and find that the two ends of the lamp are red, the lamp is black or there is a black shadow, and the lamp is not bright, the lamp of the led track lamp should be replaced in time to prevent the occurrence of ballast. Unsafe phenomena such as burnout.
