Three Key Technologies of Smart LED Flat Panel Light

Smart LED Flat Panel Light Optical Performance (Light Distribution)

The optical performance of smart LED flat panel light mainly involves the performance requirements of luminosity, spectrum, and chromaticity. According to the latest industry-standard “semiconductor light-emitting diode test method”, the main luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiation flux, luminous efficiency, color coordinates, the relevant 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 are particularly important, it is an important indicators of the lighting atmosphere and effect, while the color purity and main wavelength are generally not required.

The mainstream practice in the LED industry is in the package LED chip to form a light source or light source module, and then light distribution when made into lights so that the original traditional light source is used, because the traditional light source is 360 °. If you want to guide the light to the application side, the current Philips traditional lamps do the best, light loss also reached 40%. Many of our domestic LED downstream manufacturers apply the optical parameters of the fixtures are actually the optical parameters of the chip or light source, rather than the overall optical index parameters of the lamps.

How to better improve the performance of light, the world’s latest technology is to do light distribution on the chip package, once the chip light guide out to maintain the maximum light output, so that the light loss rate of only 5%-10%.

With the continuous improvement of technology, the light loss rate will be lower and lower, the light source light efficiency will be higher and higher. Also equipped with such a light source lamps and lanterns do not need to do light distribution, and the relative efficiency of the lamps and lanterns will be greatly improved, making them more widely used in functional lighting, the formation of a sizeable market channel.

Therefore a good LED supplier is our top priority, we do not need to spend a high cost to study our LED how to match the light for good, and do not need to spend a lot of time and experience for engineers to use software simulation, the easiest way is to let the LED white light supplier cooperate. To know, our engineers such as software to simulation, then the necessary action is the input and output. Input that is the data import, the output is the result of the simulation, then require the data must be accurate before the simulation can be correct.

Smart LED Flat Panel Light Thermal Performance (Structure)

Lighting LED luminous efficiency and power provision is one of the keys to the LED industry, at the same time, the LED PN junction temperature and shell heat dissipation are particularly important. the greater the difference between the PN junction temperature and lamp body temperature, then the greater the thermal resistance, and subsequently the light energy is converted into thermal energy consumed for nothing, and in serious cases LED damage.

A good structural engineer, not only considers the structure of the lamp and LED thermal resistance, but also considers whether the shape of the lamp is reasonable, fashionable, novel, and of course, reliable and maintainability and practicability, both from the designer’s point of view to think, but also from the user’s point of view to consider the product.

Today’s common technology is the use of aluminum substrates to package, aluminum substrate package chip heat dissipation and light conversion efficiency are the technical core bottlenecks, can not effectively control the junction temperature and stability to maintain high power light output, and the application will be because the higher the chip light efficiency, the larger the area of aluminum substrate required, will increase the cost and application volume, extremely inconvenient.
