With the continuous development of LED technology, many LED products gradually replace the use of traditional light source products in the market. China's current national standard lamps are still GB7000.1-2007 edition, the GB7000.1-2015 (hereinafter referred to as the new standard), an increase of many to adapt to the requirements of LED lamps, LED lighting
products on China's certification testing, the international Mutual recognition played a significant role.
Standard for the characteristics of LED lighting
, the use of LED lighting
as a source of the product nameplate mark to add additional requirements. For example, the new version of the standard can be installed on the surface of ordinary combustible materials, lamps are no longer required to mark the need for F symbols, which means no warning signs of the highest product requirements, the most widely used, which for some very small LED lamps, , Save the contents and space marked, but in the event of products that can not be covered by insulation materials, the relevant symbols are required to see the installation, and the minimum 25mm on each side, which for the smaller LED embedded lamps Said, need to pay attention.
Symbols for embedded luminaires that can not be covered by insulation
Different from the traditional metal halide lamp ultraviolet radiation, LED lamps and lanterns of blue light through the human retina nerve effects of the Secretary Chen rhythm, and even minor harm to the retina. The new version of the standard lamps should have a corresponding mark to warn the construction or users, to avoid the risk of blue light hazards. For portable luminaires and hand-held luminaires, if the product has a threshold illuminance Ethr according to IEC / TR 62778 and the distance between the luminaires and the luminaires reaches 200 mm or more, the standard considers that the user may be in frequent access to the luminaires, To see the light when you can first see the warning symbol to remind the user not to look at the bright light source; for fixed installation of the lamp, if the same threshold illumination, that in the specification must provide a distance to inform the construction side The product should be installed in more than the distance with the people, to avoid passing through the area of ??retinal damage.
In addition to a number of self-ballasted LED ball bulb, a lot of light LED light source is designed to replace the non-user or even irreplaceable form, which leads the user during use, can not identify the lamp can replace the light source. When a lamp life, or failure, the user is often outside the lamp from the light source can not identify the status of the lamp, which leads to the user to open the lamp cover "find out", if this time there are live parts within the lamp, it will cause Risk of electric shock. Different from the traditional light source connection form, usually with a standard lamp components, they may be E14, E27, 2G11, G5, G13, G12, etc., even open the lamp, hand replacement of light, but also has a certain electric shock protection , Non-user replaceable or non-replaceable LED light source connections are generally not used standard lamp holder, but the use of a number of connectors, and even direct welding, in the absence of standard parts to provide anti-shock, it is necessary to inform the user risk of electric shock, The new version of the standard requires the provision of electric shock outside the hood should be a warning, electric shock hazard symbols (IEC60417-6042).
Most LED modules are in the DC work, which work with the traditional light source is different, it is clear that the electrical characteristics of LED lamps and lanterns will change. The new version of the standard mainly from the creepage distance electrical clearance, electrical strength, and some related structural requirements to adapt to this change.
The new version of the standard creepage distance and electrical clearance requirements show a relaxation trend, first of all no longer distinguish between ordinary lamps and non-ordinary lamps (IPX1 above), that as long as the shell protection to pass, the lamp cavity is equivalent to IP20 environment. For the creepage distance, the equivalent DC voltage is equal to the rms value of the sinusoidal AC voltage. For the clearances, the equivalent DC voltage is equal to the peak value of the AC voltage. For the creepage distance, the creepage distance and the clearances are specified: . This means that the limits of creepage distance directly to the DC voltage as AC RMS table lookup can be calculated, while the electrical gap has a peak and RMS conversion.
Along with the creepage distance of the electrical clearance requirements decreased, the electrical strength of the test voltage also showed a downward trend. 2U + 1000, double insulated or reinforced insulation reduced to 4U +2000, some small size of the LED lighting
interior space is limited, the spacing between the poles, the pole and the shell spacing is small, due to the small size of the insulation, The terms of the relaxation, such lamps are undoubtedly easier to pass the test.
LED lamps also have programmable features, and intelligent lighting is closely related, so LED lamps compared to traditional lamps will appear a lot of control lines, dimming lines, the new standard also increases the insulation requirements between various types of lines, such as SELV Between the circuit and the LV power supply, SELV circuit and FELV circuit between. For details, refer to Appendix X of the standard, which specifies the insulation requirements for active and accessible conductive parts of circuits in various types of luminaires.
Internal and external conductors
LED lamps and lanterns of the structure is different from the traditional lamps, for cooling, size restrictions, controllable operation and other reasons, LED lamps use internal and external wiring will occur more obvious changes.
Traditional light source lamps, the external wiring generally only the power cord (non-removable soft cable cord) and the interconnection cable, there are a lot of wires within the connection lamp holder - ballast - trigger - capacitor - starter holder. LED lamps and lanterns only lead to the light leads to the LED control device, and occasionally increase the number of miscellaneous circuits (dimming circuit, constant current circuit, etc.), no longer need to accommodate a large number of components of the cavity, so LED lighting
often runs through the internal line Out of the luminaire cavity, or in an outdoor environment.
In the current version of the standard, for exposure to non-ordinary lamps outside the conductor, the standard requires the use of 60245 IEC 57 rubber line, and requires a line of at least 1.0mm2. As the large number of LED lighting
safety isolation control devices, there are many safety extra low voltage circuit, the new version of this part of the standard line with the line specifications were relaxed: as long as the SELV, and the voltage of 25V AC or 60V DC, you can use the minimum diameter 0.4mm2 of the wire, while the insulating layer material is not required. As a result, LED lamps can use more wires, such as low-smoke halogen-free line will be more LED lighting
selection, the fire will not release a large number of smoke characteristics of the very suitable for some specific places of use. Coincidentally, China's wire and cable industry is also conducting electrical equipment within the cable connecting the light source of light (structural chapters also have special requirements), the instructions should include the following: "This light source should be the manufacturer or its agents Or a similar qualified person to replace. "
Mounting surface material warning symbol
Of course, this is not all the changes, in addition to adjustment means, replaceable fuse, arm range description, controllable lamps and lanterns instructions, etc., here are not enumerated. In addition to updating the nameplate and instructions, add the relevant information, if the packaging box contains the security standard version number, should also be updated to the latest version.
