LED Aluminum-Substrate Circuit Boards for Streetlights, Tunnel Lights, Stage Lights and Spotlights
Paitai Technology manufactures LED-lighting PCBs including aluminum, FR4 and copper-based boards. Aluminum thermal-conductivity grades include0.8w/mk, 1.0w/mk, 1.5w/mk, 2w/mk, 3w/mk; copper thicknesses include1oz, 2oz, 3oz, 4oz. It supplies renowned domestic/international brands. Products serve streetlights, tunnel lights, urban wall washers, solar streetlights, high-power stadium lights, industrial lighting and high-bay lights. Aluminum-PCB use is expanding from ordinary to high-power lighting. Grades span ordinary0.8w/mk, 1w/mk or 1.2w/mk through medium, high and ultrahigh conductivity. Board thicknesses generally0.3mm~2.4mm. Copper options include18um, 25um, 35um, 70um(2oz) and 105um(3oz). Special flexible/3D aluminum PCBs bend as required without breaking. Prices/profits: Expanding production and increasing manufacturers reduce average margins. Main costs depend on substrate price and design difficulty. China's mature supply chain and improving copper-clad aluminum processes narrow the gap to overseas premium producers while offering cost advantages, accelerating adoption. Environmental awareness and growth of energy-saving/new-energy electronics are expected to expand LED and new-energy applications.

In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
As a top‑tier supplier of tunable laser chips, Shandong Zhongxin Optoelectronics Technology Company has newly launched the world’s first budget‑friendly fiber‑Bragg‑grating (FBG) demodulator and scanning module.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
