Philips Lumileds today announced an industry-leading concept that will reduce the concerns of light source manufacturers and lighting designers on white light consistency and uniformity, while greatly simplifying the design process for LED solutions. According to Philips Lumileds' "Freedom From Binning" concept, the white LUXEON emitter will emit light that is very uniform and does not require color grade sorting. The initial introduction of the new LEDs has a CCT (correlated color temperature) of 2700K and 3000K, followed by other models. These LUXEON LEDs have been tested and binned under actual operating conditions, so they can clearly understand their color, light output and efficacy. Performance data. Lumileds will continue to introduce new products this year and in the future, thus actively promoting the concept of “breaking the barriersâ€.
Michael Holt, CEO of Philips Lumileds, said: "I can arrange 1000 new LUXEON LEDs in a straight line. You will find that the consistency and color quality of each LED is the same as or better than many of the bulbs used today. The lighting industry has been pursuing the quality of light and the simplicity of design, and hopes to produce more efficient light sources at reasonable cost, thus creating a more outstanding solution than traditional electric lamps. Philips Lumileds's 'breaking off barriers' 'The concept combines our unique TFFC and Lumiramic fluorescence technology with a new production capacity that enables us to achieve 'hot' testing and color binning, drawing a new blueprint for the LED manufacturing industry, bringing us closer The distance from the lighting industry."
With these advantages, the lighting industry will be able to look at LED performance parameters in a new way. Although the specifications of the LED at 25 ° C are usually described in the manual, it is well known that the actual operating temperature of the LED is close to 85 ° C (sometimes even higher), and the listed performance data is essentially exaggerated. . The LUXEON product, which is endowed with the “Breakthrough Splitting Conceptâ€, is tested at 85°C and is therefore able to understand the actual color point and performance data. Holt said: "For the sake of accuracy and confidence, we have abandoned the selling points of higher lumens and power data. Of course we can also calculate performance under lower temperature conditions, but this deviates from the focus and may also cause misunderstanding." Most LED manufacturers' specifications contain the information necessary to understand performance at high temperatures, and the lighting industry can make actual comparisons between these products.
Philips Lumileds will release its first "Breaking Off the Fence" concept at Strategies in Light this week. It is only necessary to specify CCT when performing color sorting, centering on the black body curve under high temperature (actual) conditions. With the continuous introduction of new LUXEON products for the lighting industry, Philips Lumileds will gradually expand its "breaking off barriers" program.
Diamond turning and diamond boring
Both diamond turning and diamond boring are performed with polycrystalline diamond tools.
honing
Honing is to use the oil stone (also called honing bar) inlaid on the honing head to finish the hole.
grinding
Grinding is the use of coated or pressed abrasive particles embedded in the grinding tool, through the grinding tool and workpiece in a certain pressure of the relative movement of the surface for finishing processing.
superfinishing
Ultra-finishing is the finishing of the finished surface by using fine-grained whetstone mounted on the vibrating head.
Abrasive belt grinding
Belt grinding is the grinding of workpiece surface with high-speed annular belt.
Mirror grinding
Mirror surface grinding is a grinding method to achieve the optimum surface roughness. After grinding the workpiece, the surface roughness is not more than 0.01 micron, the light is like a mirror, can be clear imaging
