MechaTronix is developing situation specific LED coolers per LED brand. The solution offers an optimal performance which exceeds existing cooling platforms with more than 30%. As an example the company has launched the LPF67 and LPF86 advanced pin fin coolers. In a diameter of 67 mm and 86 mm, the advanced LED coolers keep respectively 3500 lumen and 4500 lumen spot and track lights on the required case and junction temperature even under a full horizontal 90 degrees positioning. The LPF47 and LPF67 advanced LED pin fin coo-lers are standard foreseen from Zhaga book 3 and Zhaga book 11 mounting holes, as well as an advanced pattern for direct mounting of COB LED modules. MechaTronix www.mechatronix-asia.com 4K autofocus zoom camera block for 30fps industrial use Sony has taken its leading 4K technology from its consumer and professional products to create what the company believes to be the worlds’ first 4K autofocus zoom camera block for the industrial market. The FCB-ER8300 delivers true 4K resolution (3840 x 2160 Pixels) at 30fps, and includes 20x zoom capability with advanced zoom technology from Sony. Using Sony Sensor technology and powered by a unique Sony image processor, the FCB-ER8300 can focus on the smallest detail whilst 70 degree Horizontal Field Of View (HFOV) allows for increased situational awareness over large areas. The 4K resolution is maintained all the way to 20x zoom. Once optical zoom range is reached Super Resolution Zoom is implemented to ensure resolution is maintained at 4K up to 20x zoom. Unlike digital zoom this does not reduce the number of pixels in the image, therefore degrading the resolution. The 60x64x105mm unit draws 3.7W with zoom/focus active. Sony Corporation www.image-sensing-solutions.eu PMIC targets USB solar chargers, wireless sensor apps The EH01-USB from Brazilian startup SiliconReef is offered as a power management IC solution for a variety of energy-harvesting applications. The EH01-USB is a power conversion and switching chip that can direct electrical energy from and to multiple sources including a DC wall adapter, photovoltaic cells and a Li-ion battery. The device enables a simple implementation of a 5-V supply, such as a USB charger compatible with the ITU standard for the Universal Charging Solution (L.1000). Using the on-chip DC/DC boost converter, the EH01 converts the voltage from a solar panel to a stable 5-V output. Excess energy is directed to a Li-ion battery charger circuit, which stores the excess energy in an external battery. The battery supply can complement the energy to the DC/DC converter when needed. The EH01 also provides an interface for battery status monitoring, which can be done via a button making a LED pulse or via serial communication. The chip has a conversion efficiency of greater than 90% according to SiliconReef, and consumes less than 5 mW in operation and less than 500μW in standby. The chip is packaged in a 20-contact QFN package measuring 5x5mm. SiliconReef (Recife, Brazil) did not indicate who is manufacturing and packing the EH01 or what process technology it is implemented in.
