LED lighting _LED lamp manufacturers
How do you know LED lighting? Shenzhen LED lamp manufacturers Shenzhen mei'erte photoelectric Co., Ltd. below for you to explain in detail the LED lighting knowledge.
LED lighting into the lighting field, has caused a new revolution in lighting technology. Due to the different shape, quantity, structure of LED size LED can be in different ways, different combinations of LED replacement lamps can be different, in the lighting field appeared in every kind of LED lighting products and traditional light source alternatives. With the continuous promotion of LED technology and the people to pursue further improve lighting visual sense, people on the LED lighting design and performance requirements more specific, which put forward higher requirements for lighting manufacturers and lighting product designers.
LED semiconductor solid-state lighting is a new developing industry, the lighting terminal product designers and lighting manufacturing personnel, not only need to master the dynamic knowledge, domestic and international standards of traditional lighting industry, knowledge and understanding of LED devices in terms of the knowledge needs, especially to accurately grasp the LED lamp, lamp definition and difference with traditional lighting lamps and lanterns. As the semiconductor industry and lighting industry, belong to different industries, as well as the current of the semiconductor LED solid-state lighting (SSL) lack of standard support enough, at present domestic LED lighting products are dragons and fishes jumbled together phenomenon, performance of the product manufacturers often with actual results far, color quality, life prediction is greatly exaggerated, cultivation the LED lighting industry in China's development and consumer confidence are bad.
This paper from the LED lamp, lamp and its status as the entrance, in the LED lamp, lamp based on the definition, analysis the characteristics of LED lamps and the existing problems, and compared with the traditional lamp performance, evaluation and design, at the same time, in view of our country and the international standard of LED lighting lamp the paper points out, should be combined with the technical elements of LED lamps to observe and track the changes and development of standard.
First, the LED lamps and the related definition
1, LED lamps
The LED package (LEDpackage): including the assembly welding line is connected to one or more LED chips or other types of electrical connections, with optical element, thermal, mechanical and electrical interface. The device does not include power and standard lamp. The device can not be directly connected to the branch circuit.
LED light engine (LED light Engine): contains the LED package (element) or LED array (module), LED drive, as well as the overall combination of other spectrophotometry, thermal, mechanical and electrical components. The device to conventional connector through a and LED lighting matching directly connected to the branch circuit, the LED lighting designed not to use standard lamp.
LED array or module (LED array or module): LED packaged in a printed circuit board or substrate (element) component or chip, possibly with optical element, additional thermal, mechanical and electrical interface to connect to the LED driver load side. The device without power supply and standard lamp. The device can not be directly connected to the branch circuit.
Non integral LED lamp (LED, lamp, nonintegrated): contains LED array (module) or LED package (element) component and a standard lamp. The device is intended to connect to the LED through standard lamp holder lamp driver. The device can not be directly connected to the branch circuit.
Integral LED lamp (LED lamp, integrated): contains the LED package (element) or LED array (module), LED drive, standard lamp base as well as the overall combination of other spectrophotometry, thermal, mechanical and electrical components. The device to the base by standard is directly connected with the branch circuit.
2, LED driver
The LED driver (LED driver): a device comprises a power supply and a LED control circuit, the purpose is to make the LED package (components), or the LED array (module) or LED lamp.
The definition of LED related interpretation provides a basis for us to distinguish between LED lamp and LED lighting, overall the LED source and LED lighting the main difference is in direct connection with the branch circuit, LED lamp is a designed not to plan and branch circuit is directly connected to the product, and the LED lighting is a designed to be directly connected to the branch circuit products.
LED light engine also belongs to the LED lamp, but their characteristics between LED lighting and integral LED lamp, difference and integral LED lamps and lanterns is that it contains a matching connector, not the standard lamp base, and the difference with the LED lighting is not directly connected with the branch circuit. The connector may have a light distribution function and standard setting, the LED light engine can improve some LED lighting maintainability.
3, LED lighting
LED lighting (LED luminaire) is includes a light emitting element LED and matching based drives, and the light distribution member, fixing and protecting the light-emitting element, and the apparatus is connected to the complete lighting appliance branch circuit component. May form light emitting device based on LED is a LED package (element), LED array (module), LED or LED light engine lamp. LED lighting plan is directly connected with the branch circuit.
Hybrid LED lighting (Hybrid LED luminaire): a light emitting element LED and such as incandescent or fluorescent lamps and other types of light source based on.
LED lighting knowledge above is the Shenzhen LED lamp manufacturers Shenzhen mei'erte photoelectric Co., Ltd. for you to explain.
MeiErTe photoelectric Limited company is located at Shenzhen Baoan Guangdong, committed to the LED energy saving lamp R & D and production, the production
