Professional Custom Lamp Holder Accessories Manufacturer

In the power shortage of energy, energy saving has become a topic of concern, energy saving lamps are gradually becoming more and more common people's vision. However, a few days ago, a survey showed that energy saving lamps product sampling rate is not high, in the field of circulation is only 55.6%, there are five major quality issues. Therefore, consumers in the choice of energy-saving lamps should pay attention to the following five aspects of the identification of products from the good or bad to prevent electric shock whether or not.

Prevention of electric shock is a safety indicator. Unqualified products due to the unreasonable cap and a plastic housing with. As a result, when the lamp is screwed in the lamp holder, lamp charged metal parts exposed, may lead to consumers when installing or removing the mechanical strength of the electric shock accident is high enough.

The mechanical strength of the main examination lamp connecting firmness. Some manufacturers have ignored the important factor of anti clockwise torque. Most of the manufacturers to buy the lamp body plastic shell are provided with screw threads, and the lamp spin on it, ignoring the bonding or crimp, thus applied clockwise torque will be tightened more and more tightly, and applied a counterclockwise torque will U-turn phenomenon, leading to unqualified. The unqualified items will cause personal injury due to the large cap lamp power is deviation off in unloading light users.

Lamp power refers to the normal operation of the power consumption, reflecting the energy consumption indicators, power is too large or too small, reflecting the actual production capacity and design capacity of the enterprise. Some companies to raise prices tend to be small power lamp nominal power lights and the measured power and the rated power of difference between the larger, damage the interests of consumers chromaticity tolerance is qualified.

This indicator is the difference between the target value and the design target value of the luminous color table of the lamp. National standards specified in the chromaticity tolerance is less than or equal to 5, and some enterprises the chromaticity tolerance average and national standards differ very far harmonic is qualified.The harmonic is the waveform analysis of the power supply current, the lower the better, otherwise it will affect the power quality and reduce the power supply efficiency.
