Luminus LEDs boost brightness in mini projectors
Luminus Devices has announced the addition of the SFT-03X Red-Green-Blue (RGB) LED chipset to its projection product portfolio enabling compact yet bright projection engines for embedded consumer and industrial applications.
Featuring a light emission size of 0.345mm2, the SFT-03X chipset is optimised for operation with small microdisplays including Texas Instruments (TI) 0.16inch DLPTM Digital Micro-Display (DMD) and sized to enable a projection engine with an extended depth of focus, allowing for a change to the projection distance without requiring manual adjustment.
Comprising individual Red-Amber, Converted Green, and Blue LED emitters with high colour saturation, the SFT-03X chipset helps create images and videos with vibrant colours that increase the perception of brightness to the human eye.
The SFM/SFT-03X LEDs deliver up to 50 lumens typical brightness at 3W electrical power in a 2 cm3 form factor in a 2-channel configuration— without requiring active cooling fans. For applications demanding even higher brightness levels, the chipset can scale up to 100 lm typical at higher input power with four active LED channels, according to Luminus.
This miniature engine can easily be embedded in a variety of consumer and industrial host devices and deliver a projected image ranging from 12 inch to 20 inch depending on ambient lighting conditions.
Consumer applications include battery-powered companion projectors for smartphones, augmented reality wearable displays, Homepods, smart home controllers, lighting track fixtures, bulb projectors, white goods such as refrigerators and washing machines where the projector delivers information signage, entertainment content or advanced lighting effects.
In industrial applications, screenless displays are not subject to damage and can be used for industrial signage, retail displays, and factory automation applications.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
