ul update direct replacement fluorescent tube led tube technical resolution

Recently, from the Ningbo Inspection and Quarantine Bureau was informed that the US Underwriters Laboratories (UL) to replace the direct replacement of fluorescent tubes led fluorescent tube lamp lights technology resolution, the latest technical resolution to replace the previous February 20, 2015 promulgated the old version, and The end of this year plans to formally incorporate UL1993 (self-ballasted lamps and their adapters) standards.

The latest technical resolution in a number of breakthroughs before the Type A LED tube into the North American market, technology bottlenecks, is expected to enable UL to help more LED manufacturers Type A led fluorescent tube lamp lightss quickly into the North American market, the direct replacement of the North American market (T12, T10, T8, T5, etc.), U-shaped tube, single-ended CFL tube and ring lamp, and so on.

The latest technical resolution of this update include: test using constant current power supply, instead of the original constant voltage power supply, to cancel the original current limit; if Type A led fluorescent tube lamp lights only replace for electronic ballasts Of the T5 fluorescent tubes, led fluorescent tube lamp lightss and lamp cap pin between the DC component does not require; if the led fluorescent tube lamp lights with a metal lamp holder or with other non-current-carrying metal parts, pin Pin pin to the metal parts of the electrical The gap requirements than before reduction; parts failure test readings from 5 seconds to 5 minutes after reading; clear cathode (lamp between the two Pin) test method.

led fluorescent tube lamp lights, a new LED light source, because of its simple installation, you can retain the original bracket directly replace the traditional fluorescent tubes, so in the home lighting has an irreplaceable position. It is precisely because of this, the market demand for led fluorescent tube lamp lights, become more and more tight. In the North American market, has been used before the fluorescent tube with the fluorescent lamp rectifier, and now the fluorescent lamp has been slowly out of the market, LED lights began to be widely used.

It is reported that exports to the US led fluorescent tube lamp lights according to the application of different, generally divided into three categories: one is Type A, generally used to replace fluorescent tubes, fluorescent lamps and ballasts work together, do not need to fluorescent lamp circuit Additional changes; one is Type B, specifically used in the factory for the products of special lamps, or in the existing special changes in the lamps on the led fluorescent tube lamp lights, and LED drive is installed in the product, as An integrated light source product; and a Type C, specifically used in the factory for the product special lamps, or in the existing special changes in the lamps on the led fluorescent tube lamp lights, and LED drive and led fluorescent tube lamp lights Is separate, not the integration of products. For export to the United States of led fluorescent tube lamp lights, the current certification test to take the standard UL1993 self-ballasted lamps, UL8750LED equipment requirements and UL Subject 1598C-Supplement SA as an additional requirement.

The face of UL led fluorescent tube lamp lights technology on the new resolution, the inspection and quarantine departments to remind the relevant enterprises can take the following response measures: First, in strict accordance with the standard safety requirements to design the lamp, such as led fluorescent tube lamp lights charged to reach Parts to protect against electric shock to meet the standard requirements, led fluorescent tube lamp lights creepage distance and electrical clearance to meet the standard requirements, especially the high-voltage part of the LED driver circuit or LED module has not been part of the safety isolation; Second, consider the LED lights Tube and the traditional fluorescent tube interchangeability, lamp size must meet the lamp standard requirements; third is to provide detailed instructions to the user installation, use, maintenance, all the details, especially the replacement steps and the type of replacement and so on.
