On the previous day, at the fourth conference of semiconductor lighting industry exchanges in Foshan City, speakers spoke highly of LED's domestic market prospects. Dr. Luo Jianghua, vice minister of the Semiconductor Lighting Industry Co-Innovation Center of Guangdong Province, said in a speech that LED visible light communication may be popularized in 2018.
Coupletech Co., Ltd could manufacture and supply a variety of nolinear Optical Crystal ( NLO crysal ), which is Lithium Triborate (LBO) crystal, Potassium Titanyl Phosphatecrystal ( KTP ) crystal, KTA crystal, Beta Barium Borate ( BBO) crystal, BIBO crystal, Lithium niobate ( LiNbO3, LN ) crystal, Potassium Dihydrogen Phosphate & Potassium Dideuterium Phosphate (DKDP (KD*P) and KDP ) crystal, periodically poled crystal ( MgO: PPLN, PPLN ) crystal and infrared Nonlinear Optical Crystals ( AgGaS2, ZnGeP2 ) crystal with top quality, unbeatable prices, prompt delivery and the best pre- and post- sales technical support and services, for not only science users but commercial customers and industrial manufacturers all over the world.
Coupletech's NLO crystal is widely used for frequency doubling ( SHG ), third-harmonic generation ( THG ), sum frequency (SFG), optical difference frequency ( DFG ), optical parametric oscillator ( OPO ), and so on.

China is the market with the fastest LED growth momentum. At the conference, Chen Wencheng, senior technical manager of Semiconductor Business Unit of OSRAM Lighting Co., Ltd., said that LED LED's market penetration rate has been increasing rapidly thanks to LED's cost reduction rate is much faster than other light sources. "By 2020, LED's market penetration will reach 70%. Mainland China and Taiwan are the fastest growing markets."
LED communication is expected to promote the use of "visible light communication is a new optical wireless communication technology that modulates the signal to LED visible light after 4 years." Dr. Luo Jianghua said at the meeting. He believes that LED can not only be applied in the field of lighting, but also through the communications industry and the Internet of Things and other areas of cross-convergence.
Visible light communication technology (VLC) refers to the use of light in the visible light band as an information carrier, and does not use a transmission medium such as an optical fiber and a wired channel, and a communication method for directly transmitting light signals in the air has high safety performance and energy saving in short-distance communication. With a wide range of applications and other advantages, the bandwidth is 10,000 times that of w ifi and 100 times that of 4G. If you want to achieve theoretical speed, it will only take 0.1 seconds to download a 1G movie.
Luo Jianghua revealed that this year is the planned start-up year for the implementation of the visible light communication technology standard and standard light component implementation plan for the joint innovation center of the semiconductor lighting industry in Guangdong Province. It is expected that after four years of talent introduction and project incubation, it can be used as a technology in 2018. The results are promoted and applied.
