Abstract: This paper analyzes the characteristics and current problems of LED lamps from LED lamps, lamps and their current status as the cut-in, based on the definition of LED lights and lamps, and has done with the performance, evaluation and design of traditional lamps. In comparison, the International Electrotechnical Commission (IEC), the US Energy Star, and the North American Lighting Society (IESNA) introduced the publication of LED lighting standards and the publication of national standards related to LED lamps in China.
LEDs enter the field of lighting, triggering a revolution in the field of new lighting technology. 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 field of illumination (for example: LED decorative lamps, LED street lamps, LED floodlight with embedded LED lamps, LED tunnel lamps, LED lamps and traffic signal lamps, etc.) and substitute traditional lighting sources (e.g.: LED replace incandescent, MR16, PAR lamp, the 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.
Semiconductor LED solid-state lighting is a newly developed industry in recent years. For lighting terminal product designers and lighting manufacturers, it is necessary to master the knowledge of the traditional lighting industry, the standard dynamics at home and abroad, and the knowledge of LED devices. In particular, it is necessary to accurately grasp the definition of LED lights, luminaires and differences with traditional lighting fixtures. Due to the different industries in the semiconductor industry and the lighting industry, and the lack of sufficient standard support for semiconductor LED solid-state lighting (SSL), there is a mixed phenomenon in domestic LED lighting products. Manufacturers claim that product performance often differs from actual results. Far from far, the color quality and life expectancy are extremely exaggerated, which is unfavorable for the development of China's LED lighting industry and the cultivation of consumer confidence.
This paper analyzes the characteristics of LED lamps and current problems from the LED lamps, lamps and their current status as the cut-in, based on the definition of LED lights and lamps, and compares them with the performance, evaluation and design of traditional lamps. At the same time, it introduces the standard situation of LED lamps in China and the world, and points out that the technical elements of LED lamps should be combined to observe and track the changes and development of standards.
First, LED lights, lamps and related definitions
1, LED lights
LED package : A component of one or more LED wafers including wire bonds or other types of electrical connectors, possibly with optical components, thermal, mechanical, and electrical interfaces. The unit does not include a power supply and a standard base. The device cannot be directly connected to the branch circuit.
LED array or module: An assembly of LED packages (components) or wafers on a printed circuit board or substrate, possibly with optical components, additional thermal, mechanical, and electrical interfaces intended to be connected to the load side of the LED driver . The unit does not contain a power supply and a standard base. The device cannot be directly connected to the branch circuit.
LED light engine (LEDlightEngine): Contains an overall combination of LED packages (components) or LED arrays (modules), LED drivers , and other luminosity, thermal, mechanical, and electrical components. The device is connected directly to the branch circuit through a conventional connector that matches the LED luminaire , which is designed to not use a standard lamp holder.
Non-integrated LED lamp (LEDlamp, nonintegrated): A component that contains an LED array (module) or LED package (component) and a standard lamp cap. The device is intended to be connected to the LED driver of the luminaire via a standard lamp holder. The device cannot be directly connected to the branch circuit.
LED lamp (integrated): Contains an LED package (component) or LED array (module), LED driver, standard lamp holder and other integral combinations of photometric, thermal, mechanical and electrical components. The device is intended to be directly connected to the branch circuit by a standardized lamp holder.
