LED Spot Lamp

DELO (Windach, Germany) now offers a new, high-intensity LED spot lamp with a wavelength of 400 nm. The DELOLUX 50 allows for fast, reliable, pinpoint curing of adhesive layers with thicknesses up to 10 mm, making it suitable for transmission through plastics like polymethylmethacrylate (PMMA), polycarbonate (PC) or polyamide (PA). The lamp’s LED heads are available in two variants with an emission spectrum of 365 nm and 400 nm. Because of the two variants, the DELOLUX 50 easily cures UV- and light-curing adhesives, regardless of whether components need to be fixed in less than one second with 365 nm or deep cured with 400 nm.

Researchers Equip Robot with Novel Tactile Sensor

Researchers at MIT and Northeastern University have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port.The sensor is an adaptation of a technology called GelSight, which was developed by the lab of Edward Adelson, the John and Dorothy Wilson Professor of Vision Science at MIT, and first described in 2009. The new sensor isn’t as sensitive as the original GelSight sensor, which could resolve details on the micrometer scale. But it’s smaller — small enough to fit on a robot’s gripper — and its processing algorithm is faster, so it can give the robot feedback in real time.A GelSight sensor — both the original and the new, robot-mounted version — consists of a slab of transparent, synthetic rubber coated on one side with a metallic paint. The rubber conforms to any object it’s pressed against, and the metallic paint evens out the light-reflective properties of diverse materials, making it much easier to make precise optical measurements.In the new device, the gel is mounted in a cubic plastic housing, with just the paint-covered face exposed. The four walls of the cube adjacent to the sensor face are translucent, and each conducts a different color of light — red, green, blue, or white — emitted by light-emitting diodes at the opposite end of the cube. When the gel is deformed, light bounces off of the metallic paint and is captured by a camera mounted on the same cube face as the diodes.From the different intensities of the different-colored light, the algorithms developed by Adelson’s team can infer the three-dimensional structure of ridges or depressions of the surface against which the sensor is pressed.

Heat Pipe Solutions for LED Devices

By Peter Ritt and Daniel Reist, Advanced Cooling Technologies (ACT), Lancaster, PA LEDs are experiencing increasing acceptance and growth across many market segments. Part of this growth is due to new, higher-power LEDs that can be packaged in increasingly small areas. However, increased power places greater importance on thermal management because of the negative effect that heat has on LED performance.

LED Phosphor Application

By Mark Tuttle, SemiLEDs Optoelectronics Co., Ltd. The most common, and cost-effective, method of delivering white light from an LED is to combine a blue “pump” LED source under a layer of phosphor or phosphor blends to achieve the desired spectrum. While there are relatively few manufacturers of high-quality blue LED die, there are a substantial number of companies that purchase those raw blue die and package them into finished white LEDs, ready for sale and eventual integration into a luminaire or replacement lamp, signage, or backlight, such as we see in our smartphones, laptops, and flat panel TVs.
