Shenzhen HuiHuangHong opto electronics Co.,Ltd , located in Shiyan which is well-known as the biggest LED industrial town in China, was established in 2008. In the beginning,we produced LED light source (such as LED modules,LED strip lights,LED light bars,LED pixel lights) for LED channel letters signs and advertising light boxes.In order to assemble easily and improve the uniformity of luminance,we developed glyph circuit board light source applied to medium or small channel letters.Further more,we choose "glyph circurt board + injection molding shell" to achieve "completely consistant,flawless,faster delivery,half cost" comparing with "glyph circuit board + metal frame", for those companies who want their brand LED signs display in hundreds or thousands retail shops. Our workshop is equipped with key facilities including SMT mouters and Lead-free reflow welding machines and wave soldering machines and injection molding machines.We already built a strict quality control system "design reviews,input process quality control,operation rules,aging test before shipping" to ensure each product you will get is without fault. "Serve Customers" is the truth what we consistently believe and perform.Looking forward to a splendent grand cause in the long term with you.
