Four tips to identify inferior lamps
Lighting appliances are indispensable supplies in people's daily lives, and their safety and quality are directly related to the safety of users' lives and property. Lamp products with poor quality and low safety level increase the risk of electric shock and fire when used. Poor quality lamps are manifested in signs, structures, external and internal wiring, protection against electric shock, insulation resistance, etc. Below we will introduce to you four tips for identifying inferior lamps!
(1) The internal wiring and external wiring are unqualified. Stage lighting equipment
The wire of ordinary lamps is lower than the minimum cross-sectional area of 0.75mm2, and other lamps are the standard requirements of 1mm2; the external wiring inlet and outlet of the lamp are rough and sharp, without chamfering treatment, and no fixed measures are taken for the incoming wire, resulting in the wire insulation layer is easy to be scratched.
(2) The mark is unqualified.
The lamps do not have any signs or the signs are incomplete, and some signs have poor durability. There is no manufacturer name, registered trademark, "CCC" compulsory certification mark, rated voltage, rated maximum ambient temperature, product model or type serial number, rated power, etc. on the lamp.
(3) The anti-electric shock protection is unqualified.
It is mainly manifested in the screw lamp base of various lamps. Because the structure, size and insulation performance of the lamp holder are not processed and manufactured according to the standard, the bulb cannot be completely screwed into the lamp holder, and the live part of the metal screw of the bulb is exposed, which is easy to be touched by people and cause electric shock accidents.
(4) The structure is unqualified.
Mainly the wire pipe inside the lamp (tube for internal wiring, wiring tubes, grooves, etc.) is not smooth, there are edge edges, burrs; the electrical connection of the lamp holder falls off or becomes loose; Insulating liners or bushings do not hold securely in place.
