Lighting fixtures are an indispensable appliance in people's daily life. Their function is to provide artificial lighting to meet the lighting needs of various places. Its traditional definition is to include all the zeros, components, and wiring accessories necessary to connect and disconnect the power source, except for the light source. The light source refers to an object that is itself emitting light and can continuously emit light.

LEDs of different shapes, numbers, and sizes can be arranged in different ways, and the LED structures in different LED replacement lamps can be different. Various LED lighting products appear in the lighting field (for example, LED decorative lamps, LED road lamps, LED floodlights, embedded LED lamps, LED tunnel lamps, LED desk lamps and traffic signal lamps, etc.) and traditional light source alternatives (eg LED replacement incandescent lamps, MR16, PAR lamps, straight tube fluorescent lamps) T8/T12, etc.). With the continuous improvement of LED technology and the further improvement of people's pursuit of lighting sensory vision, people have more specific requirements on the design and performance of LED lamps, which puts higher requirements on lamp manufacturers and lighting product designers.
LEDs come in a variety of forms, including LED packages, LED arrays, LED modules, LED lights, etc., and the combination of them is different, including standard lamp head, built-in, stand-alone and monolithic, which also form different maintenance. Types such as light source replaceable and non-replaceable, maintainable and non-maintainable. In addition, the dazzling design and style are difficult to define by traditional distinction. Especially in the definition of LED lamps and LED lights, some vague and even wrong concepts have caused confusion in the industry. It will have an adverse impact on the development of the LED lighting industry and the development of standards and testing.
As a new lighting product, how to use LED light source to meet the application requirements, and scientific evaluation of its safety, laser safety, performance and energy efficiency is currently facing LED lighting products. A big topic. To solve this problem, we should begin to understand the basic principles of the luminaire standard from the understanding of the existing luminaire standard system. When we look at the characteristics of the LED luminaire from a scientific perspective, we will understand that the existing luminaire standard has covered the LED luminaire. Due to some characteristics of LED lamps, additional requirements for LED lamps are required, and special requirements for LED lamps are required.
Currently, in the field of product testing, the new IESLM-80 (LM-80) industry standard enables LED manufacturers to analyze individual LED lumen maintenance under actual operating conditions. However, the LM-80 does not cover LED luminaire measurements and does not provide a means of assessing LED life. Therefore, in the actual solution, the luminaire manufacturer lacks other useful information to better understand and predict the life behavior of the LED, especially the correct evaluation of the life of the LED luminaire, which is also an important reason for affecting the wholesale market of lamps. one.
