In recent years, with the continuous development of semiconductor lighting technology, LED general lighting double-ended lamps in China has been developing rapidly and a lot of promotion. Europe is an important export market for lighting, but LED lamp on the European safety standard EN 62776 has yet to formally promulgated (draft version of the content 34A / 1501 / NP in early 2011 on the release), so far the major European CB LED lamp standard safety testing and certification used are not uniform.
Manufacturers in the design and manufacturing process, how to eliminate the security risks LED lamps tubes lights replace traditional double-ended fluorescent lamps, to achieve certification standards, passed the export certification, to avoid the risk of recall and ban products because of a security risk? This paper mainly explore techniques of the current practice of the major European certification bodies and manufacturers need to focus on.
(Author Note: IEC 62776 Ed 1.0 Double-capped LED lamps tubes lights designed to retrofit linear fluorescent lamps – Safety specifications will be released in December 2014; expects EN 62776: 2014 will be released later) European certification bodies with EN 62560 (LED self-ballasted lamp standard), EN 62493 and EN 62471 to issue CE certificate LED lamp, evaluation and testing was also taken of EN 60061-1, EN 60061-3 for G5 / G13 lamp size requirements, and EN 61195 (Double fluorescent – safety specifications) some provisions, such as tube length measured cap torque testing. Features: single-ended charge, one end of the L / N, two pins short-circuited at the other end. Not evaluated Replacement Starter (author Note: Replacement Starter refers to replacing the fluorescent lamp starter of an internal short circuit or fuse contained within the starter, the main role in communication circuit). Instructions will require the LED lamps tubes lights can only be used in ballast lamps, fluorescent tubes replaced with LED lamps tubes lights to replace fluorescent lamps with starter Replacement Starter. A German certification body with standard E DIN EN 62776 (VDE 0715-16) (Double-capped LED lamps tubes lights for general lighting services-Safety specifications) of the LED lamp to evaluate and certification. Product name usually named LED lamp. Features: single-ended charge, one end of the L / N, two pins short-circuited at the other end. When replacing fluorescent tubes with LED lamp, do not allow the line to change the lighting, LED lamps tubes lights can only be used in ballast lamps, the need for Replacement Starter, can only be replaced with LED lamps tubes lights fluorescent tubes, fluorescent lamps replaced enabled Replacement Starter Hui is. European certification bodies as well as with the EN 60598-1, EN 61347-2-13, EN 61347-1, EN 62031, EN 61195, EN 62493 and EN 62471 to issue CE certificate LED lamp. Evaluation and testing was also taken of 34A / 1501 / NP (draft IEC 62776 of content). In addition, with the EN 60061-1, EN 60061-3 for G5 / G13 lamp dimensions assessment of the size of the lamp with the EN 60081 assessment with EN 60155 for Replacement Starter assessment. The main line is on the 34A / 1501 / NP, evaluation and testing is focused on it. Features: single-ended charge, one end of the L / N, two pins short-circuited at the other end. Not allowed to change the line fixtures, LED lamps tubes lights can only be used in ballast lamps, the need for Replacement Starter, can only be replaced with LED lamps tubes lights fluorescent tubes, fluorescent replacement starter with Replacement Starter. In summary, although the major European certification testing organizations in the issue of LED lamps tubes lights used standards vary, but the basic idea evaluate LED lamp is the same. In the near future, with the IEC / EN 62776 is officially promulgated, practice various certification bodies will be unified, so we will be discussing technical points, the content is built around the current draft of IEC 62776 will be. Analysis Techniques Draft IEC 62776 applies to this LED bulb: double-ended use G5 or G13 lamp rated power does not exceed 60W, rated voltage not exceeding 250V, without modifying or disrupting the existing lighting conditions, LED lamps tubes lights can directly replace fluorescent lamps pipe (see sketch below replacement before and after replacement). label: Manufacturer’s name or trademark; Rated voltage; rated power; Rated frequency; Maximum ambient temperature ta (if applicable); CE mark (CE certification have to do), WEEE logo. For the rated current, non-dimmable flag (if not apply to the dimming circuit), applies only to ballast instructions do not apply to the design using fluorescent tubes emergency lighting instructions, these areas can be selectively Information placed label, packaging or installation instructions inside. Replacement Starter Tags: Manufacturer’s name or trademark; Model; Warning “applies only LED lamps tubes lights are equipped.” Instructions: Description of the product package which includes LED lamps tubes lights and Replacement Starter; LED lamps tubes lights replace fluorescent tube specifications (length and power); Use the information environment (dust and water); Lamps can not make any structural changes to the line or explanation; Product ambient temperature range; Installation diagram. Interchangeability requirements G5 and G13 lamp sizes: must comply with IEC 60061-1 and IEC 60061-3, the following table:

LED lamp size measurement: When were placed in -20 ¡ã C and 80 ¡ã C ¡À 5 ¡ã C environment for 5 hours and immediately taken out dimensional measurements in accordance with IEC 60081 (measured figure A, B, C and D) , the measured value can not exceed the specified limits. The following G13 lamp T8 and T10 tube size requirements described as an example (the length specification is a common choice of 600mm, 900mm, 1200mm and 1500mm). Replacement Starter: the need to meet the relevant test requirements of IEC 60155 standard Chapter 1 inside. – Labeling requirements (manufacturer’s name or trademark, model, and warnings “is only available with the LED lamp”); – Moisture, insulation and voltage requirements (to meet basic insulation); – Size and gauge requirements; -0.6Nm Torque testing requirements; – Mechanical testing requirements drum (20); – Heat requirement (125 ¡ã C, 168h); – Material Testing Requirements (125 ¡ã C ball pressure test and 650 ¡ã C glow wire test) Temperature and power: rated voltage and 25 ¡ã C ambient temperature, the measured temperature of the outer surface of the LED lamp can not exceed x ¡ã C (x still under study, there may be a 60 ¡ã C-80 ¡ã C), LED lamp power consumption and can not be replaced is greater than the power consumption of fluorescent tubes. Launcher – tube mix: – Fluorescent and LED lamp starter mix -Replacement Starter mixed with fluorescent tubes During the test, the tube can not have smoke, fire and flammable gases, live parts can become accessible. Protection against electric shock Test fingers 10N not touch the metal parts inside, basic insulation external metal parts (except head) and live parts. Single-ended lamps must be charged, namely L and N at the same end, the other end of the two pins are shorted, capped at both ends of the pins can not have any electrical connections, when one end of the lamp from the lamp holder mounted sockets or demolition the next, the other end of the pin is not charged (need to meet the requirements of IEC 60598-1 Appendix a). Live parts inside the lamp housing and accessible parts to meet the double or reinforced insulation. Between the lamp and the lamp body to be firmly secured to the cap can not be removed by hand, so as not to cause internal manpower can touch live parts. Tide state test, insulation resistance and dielectric strength Tide state test: 20-30 ¡ã C; 91% – 95%; 48h; Insulation resistance and electric strength: Between -L and N (> 2MW; 2U + 1000V); -L / N and accessible housing (> 4MW; 4U + 2000V); – End of the pin and the other end of the pin (> 4MW; 4U + 2000V); – Primary and secondary circuits (safe isolation from supply) (> 4MW; 4U + 2000V or 3000V); – Safety extra low voltage output and accessible housing (> 1MW; 500V); The mechanical strength of the cap requirements LED lamp lamp to withstand the torque in the following table, can not have more than six degrees of displacement. When the lamp is not by means of screws or other mechanical means fixed, for example, just glue fixed, then the LED lamps tubes lights needed at 80 ¡ã C ¡À 5 ¡ã C temperature for 2000 ¡À 50 hours of storage aging test before making a torque in the following table test, can not have more than six degrees of displacement.
Temperature test EN 60598-1 according to the normal temperature inside its inspection, the LED lamps tubes lights and magnetic ballasts Replacement Starter put lamps at 1.06 times the rated voltage, measuring the temperature of various critical components or parts. Materials Testing Provide an external electric shock insulation or retaining live parts in position insulating material, ball pressure test temperature of at least 125 ¡ã C; glow-wire test temperature is 650 ¡ã C. Fault Test Component failure test, you need a sense of ballast distribution and Replacement Starter conduct; Electrical test extreme conditions: 150% of rated power or claimed by the manufacturers of the most unfavorable conditions of electrical test until the temperature is stable, temperature or 1 hour to appreciate within no more than 1K, after the temperature stabilization, LED lamps tubes lights need in extreme conditions stable 15 minutes; LED lamps tubes lights with different types of ballasts (magnetic ballasts and electronic ballasts) risk assessment; Lamp ballast short circuit risk assessment (LED lamp powered directly condition assessment); During the test, not fire, shall produce flammable gases, live parts can become accessible. Creepage distances and clearances Creepage distances and clearances according to standard IEC61347-1 and mainly IEC60598-1. The following operating voltage 250V Case: Between -L / N: cr> 2.5mm; cl> 1.5mm; Between -Fuse: cr> 2.5mm; cl> 1.5mm; – Safety isolating transformers: between input and output: cr> 5.0mm; cl> 3.0mm; – Contact between live parts and metal: cr> 5.0mm; cl> 3.0mm; – Output (LED modules) and the contact between the metal (> 25V <= 50V): cr> 1.2mm; cl> 0.2mm If there is a palpable aluminum, pay attention to the internal basic insulated wires can not be in direct contact with the aluminum shell, internal requirements shall be double insulated wire leads or substantially insulated wire plus a layer of heat-shrinkable tubing. Aluminum plate above the insulation is considered to be basic insulation only, so if you use non-isolated power supply, then the structure of the aluminum plate and aluminum can be touched in direct contact with just basic insulation, this structure can not meet the standards. Safe isolated power output can not be in contact with the wire and the primary circuit power supply or the output wires and LED module is not safety extra-low voltage, and become the basic insulation. Sectional area of ??the wire and the insulating layer thickness of the internal reference of the requirements of IEC 60598-1. LED lamp IP protection requirements If the LED lamp is used in wet environment, the need to refer to IEC 60598-1 be IPX5 and IP6X testing. Before IP test, according to IEC50598-1 standard 12.3 provisions require, Ta is set to its nominal value of 10K higher ambient temperature, time of 240 hours, a durability test. Light is required for biosafety In any case, LED lamp radiation level can not exceed IEC62471 of RG1. In summary, not difficult to find, in fact, LED lamps tubes lights can be divided into safety and protection against electric shock safety interchangeability two main lines. Interchangeability security main consideration when replacing fluorescent tubes LED lamp, LED lamp itself and when it is applied to the lamp, whether electrical safety is guaranteed, thus including cap size, cap torque, tube length, tube weight, Replacement Starter’s a set of evaluation assessment, and temperature exchange misuse risk assessment are all around the main line. Protection against electric shock mainly on the LED lamp itself shock hazard assessment, mainly through structural inspection, creepage distance and clearance measurements, insulation resistance and voltage test to achieve.
