Generally speaking, the lamps and lanterns of the hotel are customized engineering lamps, because our household lighting lamps and lanterns can not be used as the lamps and lanterns of the hotel, so the lamps and lanterns we see in the hotel are relatively rich crystal lamps and so on. After the engineering lamps and lanterns are customized, how should we inspect the goods in the later inspection.

General test methods for engineering lighting customization. According to the regional specifications customized for engineering lamps, the corresponding voltage and leakage current shall be debugged first. Then connect the wire at one end of the voltage withstand machine to the positive pole of the outlet of the lamp & lt; The switch is open & gt;, Then connect the conductor at the other end of the voltage withstand machine with the conductivity gun & lt; Or conductive rod & gt; Open to the outer metal part of the lamp and hit it immediately. If there is no sound from the press, the power line of this pole of the lamp has been inspected; Otherwise, there will be leakage or breakdown.

Check the negative power line of the lamp in the same way and pay attention to personal safety. Next, the engineering lamps can be customized. Turn the bulb on the lamp cap and connect it to the power line to initiate switch inspection. If one end of the lamp is a custom-made metal lamp cap, and the other end of the lamp cap is a metal lamp cap, the other end of the lamp cap is a custom-made one. It can also be checked with an electrode meter. The method is the same. If the pointer shakes, it will open the circuit, otherwise it will open the circuit. Customized polarity of engineering lamps is distinguished. Black is the positive pole and white is the negative pole of a single power line. The customized two core power cord for engineering lamps has one word as the positive pole and one without word as the negative pole. The small end of the polarity plug is positive and the large end is negative. The metal in the center of the customized lamp cap of engineering lamps is the positive pole, and the metal on the surrounding surface is the negative pole. For the customization of engineering lamps, the negative end of the electrode meter contacts the negative end of the power line or plug, and the positive end of the electrode meter contacts the negative end of the lamp cap. The needle movement is correct, and vice versa.
