[Source: Gaogong LED's "LED Good Products" magazine February issue / Wang Lirong ] "We are very optimistic about China's LED photodetection equipment market in the future, because LED is the general direction of the future lighting industry." Labsphere China District sales manager Xiong Weihua said.
In 2009, Lanfei Optics established a wholly-owned subsidiary, Shanghai Lanfei Optical Instrument Co., Ltd., which is a clear signal for preparing for the outbreak of the Chinese LED market.
As a leader in light measurement and optical diffuse reflective coatings, Lanfi Optics' products include LEDs, lasers and conventional light source measurement systems, uniform light sources for imaging equipment calibration, spectroscopy accessories and highly diffuse reflective materials. Wait. Lanfi Optics hopes to expand its market share of its products through its new high-precision LFC system launched in 2012.
High precision
According to reports, the LED photometric and colorimetric measurement system LFC system is a set of full-spectrum flux solutions designed and developed based on international standards and industry test standards. It features high-end spectrometer and LFCSPEC software, combined with Lanfei optical measurement integrating sphere and NIST traceable standard lamps for testing the optical, chromatic, and electrical properties of LEDs, LED modules, LED lamps, and general lighting devices.
The biggest achievement of the high measurement accuracy of the LFC system is its integrating sphere with high measurement accuracy.
“Standard lamps used in other similar products on the market only provide information on luminous flux and color temperature, and there is no spectral data accurate to 1 nm interval. At the same time, the diffuse reflectance and Lambert characteristics of the integrating sphere coatings of these products are poor, without the use of auxiliary Lamps, the measurement results are easily affected by the lamps themselves," said General Manager of Labsphere China.
According to reports, this integrating sphere system uses NIST traceable calibration standard lamps, traceable data to 1nm, fine-screening each full-spectrum and full-flux standard lamp, high-precision calibration under IESNA recommended method to ensure its stability Sex and reproducibility.
At the same time, all standard lamps pass the 1% rated life test and stability and repeatability tests, and finally the calibration data is obtained by NIST flux standard lamp test, which can provide the integrating sphere and spectrometer system in the 350nm to 1050nm bandwidth. Very accurate full radiant flux response calibration to ensure source reliability.
At the same time, Lanfei Optics also provides three sets of standard lamps, which are convenient for customers to conduct mutual school and extend the service life of each standard lamp.
The integrating sphere uses 680 white reflective coating. The reflectivity of the coating is as high as 94-96% in the wavelength range of 300 to 1200 nm. It has good Lambertian properties, making each reflection a diffuse reflection instead of Specular reflection greatly improves the uniformity of light on the inner wall of the ball, making the test more precise.
According to the military, this integrating sphere system has an auxiliary light correction function. When measuring large luminaires, because the luminaire's own casing absorbs light and affects the final measurement results, the auxiliary lamp correction can overcome this problem, ensuring that the luminaire itself is the final measured result, ensuring the accuracy of the measurement.
Easy to operate
In terms of system compatibility, LFC-SPEC software is designed with Windows-compatible application modules for intuitive calibration and analysis, from simple light bulbs to LEDs to solid-state lighting components and traditional indoor and outdoor lighting systems. The radiance, luminosity and chromaticity characteristics of the light source, the instantaneous nature of which allows the user to monitor optical and electrical performance against the elapsed operating time.
At the same time, the user can match the spectrometer's optical fiber with the integrating sphere detection port produced by other companies with the appropriate spectrometer, power supply and adapter. The software can also control the integrating sphere produced by other companies.
The DLL driver conforms to the standards of the LFC-SPEC platform, including examples written for the most popular programming languages, allowing customers to extend the Feb.2013 BEST LED PRUDUCTS 59PROCESSES AND EQUIPMENT | process device program. If the customer is ready to increase production, its complete design and user graphical interface can easily meet the high performance operational requirements of the customer and are easy to use from the laboratory to the production floor.
The LFC system is compatible with 2pi and 4pi measurements by selecting the appropriate calibration lamp, giving end users the flexibility to make measurements based on Energy Star or international standards. The 2pi and 4pi compatibility provides more operational flexibility and is compatible with more samples to be tested.
The integration of the software and the integrated cabinet allows the customer to control the power switch with a click of a mouse. By switching the switch on the cabinet, the standard and auxiliary lamps can be easily switched.
