At present, the main market of LED energy-saving lamps has gradually changed from overseas to globalization. Exporting overseas markets must pass the inspection, and the specifications and standards for domestic LED energy-saving lamps are becoming more and more strict. Therefore, certification testing has become the work of LED lamp manufacturers. Focus. The following 200w Led Flood light manufacturers share four key points for LED energy-saving lamp testing standards:
1. material
The led energy-saving lamp can be made into various shapes such as a ball-type straight tube type. For example, a straight tube type LED fluorescent lamp has the same shape as an ordinary fluorescent tube, and the power module and the light-emitting diode are wrapped by a tubular transparent PC polymer casing of the fluorescent lamp. inside. The transparent polymer housing provides fire and shock protection in the product. According to the standard requirements, the energy-saving lamp housing material must be above the V-1 level, so the transparent polymer housing must be of V-1 or higher. The product shell must reach the V-1 level, and its thickness must be greater than or equal to the thickness required for the V-1 grade of the raw material. The fire rating and thickness requirements can be found on the UL yellow card of the raw material. In order to ensure the brightness of LED energy-saving lamps, many manufacturers often make transparent polymer shells very thin, which requires the inspection engineer to pay attention to ensure that the material meets the required thickness of the fire rating.
2. Drop test
According to the requirements of the product standard, the product should simulate the drop test that may occur during the actual use, and the product should fall from the height of 0.91 m to the hard board. The outer casing of the product should not be broken to expose the dangerous parts inside. When the manufacturer chooses the material to make the product casing, this test must be done in advance to avoid the loss caused by the mass production failure.
3. Dielectric strength
The transparent housing encloses the power module inside, and the transparent housing material must meet the electrical strength requirements. According to the standard requirements, based on the condition of 120 volts in North America, the internal high-voltage live parts and the outer casing (tested with metal foil) should be able to withstand the 1240 volt AC strength test. Under normal circumstances, the thickness of the product shell reaches about 0.8 mm, which can meet the requirements of this electric strength test.
4. Power module
The power module is an important part of the LED energy-saving lamp, and the power module mainly adopts the switching power supply technology. According to the type of power module, you can consider testing and certification with different standards. If the power module is a class II power supply, this can be tested with UL1310. The class II power supply is a power supply that uses an isolated transformer with an output voltage lower than 60 VDC and a current less than 150/Vmax amps. For non-class II power supplies, UL1012 is used to test the certification. The technical requirements of these two standards are very similar and can be referred to each other. The internal power module of most LED energy-saving lamps uses a non-isolated power supply. The DC output voltage of the power supply is also greater than 60 volts. Therefore, the UL1310 standard is not applicable, and UL1012 is applicable.
