LED lighting technology is the key to these? What do you think
Optical performance (light distribution)
The optical properties of LED lamps mainly relate to the performance requirements in terms of luminosity, spectrum and colorimetry.
According to the industry standard "semiconductor light-emitting diode test method", there are luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity and dominant wavelength Color index and other parameters.
LED lamp commonly used white LED, color temperature, color rendering index and illumination is particularly important, it is an important indicator of lighting atmosphere and the effect, and the color purity and the main wavelength is generally not required.
Thermal properties (structure)
Lighting LED lighting efficiency and power supply is one of the key LED industry, at the same time, LED PN junction temperature and the case of the cooling problem is particularly important. PN junction temperature and the greater the difference between lamp body temperature, then the greater the thermal resistance, along with light energy is converted into heat consumed in vain, LED damage in severe cases.
A good structural engineer, not only to consider the structure of the lamp and LED thermal resistance, but also consider the shape of the lamp is reasonable, stylish, innovative, of course, reliability and maintainability and practicality, it is necessary to stand on the designer Point of view, but also stand in the user's point of view to consider the product.
Electrical properties (electronic)
If a lighting compared to a girl, then the light is her connotation, the structure is her appearance, the electron is her heart. Attract people's attention are always those beautiful, stylish beauty, the product is also true.
People do not have a heart without life, the lamp is not electronic power is not a good drive power can also determine the life of a product.
Electronic standards and parameters tend to be much more complicated than the structure, pre-R & D effort is relatively large. The current technology trends and updates are changing day by day. Engineers have to spend a great deal of time studying, absorbing, decomposing and applying new technologies.
Electronic design of the early plans, mid-term implementation, the latter part of the whole process of forming the need to form a document, the formation of data, which is the most cumbersome thing in the design. For example: a power supply design a pre-program, product profiles, standards based on standards, safety specifications, electrical performance expectations, process requirements, raw material evaluation, test methods, etc. should be formed system files.
