Identification and improvement of general lighting LED and final product application standards

Used to measure the quality of the product is the product standards, product standards, insight is known as the law of technology.

First, the composition of the product standard system

LED is a new type of lighting electrical products. LED products, including its own, supporting the control device and the light source for its products, related to the standard terms of these products are mainly composed of the following aspects.

1 in the use of products related to the safety of people's lives and property clause

As electrical products, safety requirements in use is the most important part of the internationally recognized, in this regard, China's product standards are almost identical with IEC standard, even our own set of safety standards, but also the basic reference to IEC and / or ANSI, and are regarded as mandatory standards to be promulgated and implement. For example, the GB19510/IEC61347 lamp control device series and the GB7000/IEC60598 lamp series standard and the light source safety standards in the vast majority of the terms belong to this category.

2 LED, control devices and lighting performance requirements

Consumers to buy the product is actually the use of the function of the purchase of the product, and the use of the product function is to rely on the performance of the terms of the assessment to achieve. As LED lighting products and the corresponding ancillary products is no exception, the new formulation of the (Draft) "general lighting LED module", "performance requirements for general lighting self ballasted LED lamp performance requirements" and "LED module with DC or AC electronic control device performance requirements" standard, light effect, the color characteristic, attenuation, life and energy efficiency indicators and the lamp luminosity distribution and efficiency index reflects this requirement.

3 LED, control devices and lamps to meet the requirements of each other

This part of the standard can be divided into:

(1) the design requirements of the light source to the control device

The control device of the lamp is used for the light source. It should be said that the safety indicators of the lamp control device is the most important, but most of its assessment requirements and other similar appliances, it is easier to understand. As the requirements and source with relatively the inherent mechanism is more profound, the normal working state of the light source is provided by the main control device, with the performance of the control device and the light source is directly related to the light emitting efficiency and light stability and service life, and affect the overall energy efficiency of the system.

(2) the design requirements of light source for lamps and lanterns

When the light source is installed in the lamp, the working condition of the lamp is decided by the design structure of the lamp. If the design structure of the lamp is not reasonable, it will seriously affect the normal work and service life of the light source. For example, the use of LED road lamps, lamp requires good sealing, to ensure the waterproof and dustproof function, and has good heat dissipation, to ensure that LED can in many unfavorable conditions, the temperature is still at a reasonable level.

4 power supply for lighting electrical appliances working conditions

As an electrical appliance, it is necessary to comply with the assessment requirements of the power supply, so as to ensure the normal operation of the power supply system and to maintain a high power efficiency. In this respect the terms of the GB17625.1/IEC61000-3-2 line power factor, supply current harmonics and GB17625.2/IEC61000-3-3 voltage drop and flicker.

5, the electromagnetic interference to the outside world as well as the resistance to external electromagnetic interference

As the use of electrical appliances, should limit electromagnetic interference to other electric appliances, such as GB17743/CISPR15 (EMI) in the power supply terminal harassment and radiation harassment, but also can resist possible electromagnetic interference (EMS), such as a variety of resistance to various electromagnetic IEC61547 and FCC standards in terms of interference.

Two. Identification and introduction of lighting LED and its final product application standards

From the above description about the content, for any kind of product, is generally not a single standard can completely cover all requirements, any product standards are for a certain characteristics of the corresponding products, and is applicable to a certain range. It is a common practice that all kinds of standard systems in the world are complemented by a number of standards, which are mutually complementary, referenced and supported each other.

1 LED lighting fixtures and final product standards

Due to our knowledge to master the legacy of the planned economy of industry separated and numerous lighting industry practitioners of the narrow, often hear some people say "LED lighting and the application of the final product is not the appraisal standard, in fact this is very naive. For example, using LED as light source of various final products, lamps are composed of or self ballasted lamps from the use function of product attributes and no change, so the standard requirements for lamps also cover almost the assessment of their contents. At present, the production of a variety of lamps using LED light source, the lamp must meet the corresponding safety standards, electromagnetic compatibility requirements and lighting requirements. In addition, the assessment criteria for the lighting effect of the luminaire is also suitable for this kind of lamps. In other words, the use of LED as the light source lighting products (also the application of the end product) in this regard has already existed in the assessment requirements. There are still many practitioners in our industry is not recognized.

2 LED control device product standards

In the LED control device, the international year before the IEC61347-2-13 security standards have been met
