LED Panel Lights Of The Three Key Technologies
LED panel lights of the three key technologies
Light performance (with light): LED panel light optical performance is mainly related to the photometric, spectral and chroma and other aspects of performance requirements. According to the latest industry standard "semiconductor light-emitting diode test method", there are luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiation flux, luminous efficiency, color coordinates, color temperature, color purity and main wavelength, Color rendering index and other parameters. LED panel lights commonly used white LED, color temperature, color rendering index and illumination is particularly important, it is an important indicator of lighting and the effect of color, and color purity and the main wavelength is generally not required.
Thermal performance (structure): lighting with LED luminous efficiency and power supply is one of the key LED industry, at the same time, LED PN junction temperature and shell cooling problem is particularly important. PN junction temperature and lamp body temperature difference is greater, then the greater the thermal resistance, followed by light can be converted into heat consumed in vain, serious damage to the LED. A good structural engineer, not only to consider the structure of the lamp and LED thermal resistance, but also consider the appearance of the lamp is reasonable, stylish, innovative, of course, reliability and maintainability and practicality, it is necessary to stand in the designer The angle to think, but also stand in the user's point of view to consider the product.
Electrical performance (electronic): If a lighting compared to a girl, then the distribution of light is her connotation, the structure is her appearance, the electron is her heart. (To attract people's eyes are always those beautiful appearance, fashion beauty, the product is the case). People do not have no heart life, no electronic lights are not a power supply, a good drive power can also determine the life of a product. Electronic standards and parameters are often much more complex than the structure, pre-development of energy investment is also relatively large. The current technology trends and updates are changing, one day a day, engineers have to spend a lot of energy to learn, absorb, decomposition, application of new technologies. Electronic design of the early plan, the implementation of the latter part of the formation of the entire process to form a document to form the data This is the most cumbersome design. For example: a power supply design of a pre-program, product introduction, the standard specification basis, safety specifications, electrical performance expectations, process requirements, raw material assessment, test methods, etc. to form a system file.
