Performance and special standards of LED lamps

Lighting fixture is an essential electrical appliance in people's daily life. Its function is to provide artificial lighting to meet the lighting needs of various places. Its traditional definition is to include all the parts and components needed to fix and protect the light source except the light source, as well as the circuit accessories necessary to connect with the power supply. The light source refers to an object that is emitting light and can continue to emit light.

Now LED has entered the lighting field, triggering a new revolution in the field of lighting technology. Due to the different shapes, quantities and sizes of LEDs can be arranged and combined in different ways, and the LED structures in different LED replacement lamps can be different, etc, in the field of lighting, various LED lamp products ( For example: LED decorative lamps, LED road lamps, LED projection lamps, embedded LED lamps, LED tunnel lamps, LED desk lamps and traffic signal lamps, etc)And traditional light source alternatives ( For example: LED replaces incandescent lamp, MR16, PAR lamp, straight tube fluorescent lamp 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, this puts forward higher requirements for lamp manufacturers and lighting product designers. There are various forms of LED, including LED package, LED array, LED module, LED lamp, etc. The combination mode with lamps is therefore different, including standard lamp cap type, built-in type, independent type and integral type, this also forms different maintenance types, such as light source replaceable and non-replaceable, maintainable and non-maintainable. In addition, the dazzling appearance design and style are difficult to define by traditional differentiation methods, especially in the definition of LED lamps and LED lamps, some vague and even wrong ideas have caused chaos in the industry, which will have a negative impact on the development of LED lighting industry and the field of standard setting and testing. As a new lighting product that attracts people's attention, how can lamps using LED light sources meet the application requirements, and its performance in safety, laser safety, performance and energy efficiency is scientifically evaluated, which is a major topic facing LED lamp products at present. To solve this problem, we should start from understanding the existing lamp standard system and clearly define the basic principles for formulating lamp standards. When we see clearly the characteristics of LED lamps from a scientific perspective, we will understand that, the existing lamp standards have covered LED lamps. Due to some characteristics of LED lamps, additional requirements need to be put forward for LED lamps and special requirements standards for LED lamps need to be formulated. At present, in the field of product testing, the newly introduced IESLM-80 (LM-80) Industry standards enable LED manufacturers to analyze the maintenance of individual LED lumens under actual working conditions. However, LM- 80 does not cover LED lamp measurement and does not provide a method to evaluate LED life. Therefore, in practical solutions, lamp manufacturers lack other useful information to better understand and predict the Life behavior of LED lamps, especially to correctly evaluate the life of LED lamps, this is also one of the important reasons that affect the wholesale market of lamps.
