Ordinary 60W incandescent bulbs only convert about 8% of their input energy into usable light. Most of the remaining energy is conveniently radiated out as infrared (73%) or conducted out through the lamp base (19%). In the case of a visible-spectrum HBLED however, there is negligible IP emission - thus the die's excess heat must be removed by conduction, convection or both.

The use of proper lighting is often overlooked when designing a machine vision application. More robust and accurate inspections can be achieved when appropriate lighting techniques are utilized. This application note discusses considerations when selecting lighting equipment and demonstrates how to utilize the Direct Drive lighting controller feature on the NI 17xx Smart Camera with LabVIEW or Vision Builder for Automated Inspection.

The National Instruments Green Engineering Technical Library contains a wide variety of resources for environmental application development techniques, example programs, and case studies.

Significant time and money has been invested in researching the use of wireless technology for remote monitoring. Yet, significant wireless deployments are just beginning to materialize in industry. There are many advantages in eliminating cables in remote monitoring applications, but there are also many challenges. As standards such as Wi-Fi and ZigBee continue to mature for use in wireless sensor networks, those challenges are being addressed. This paper discusses how wireless technology has evolved and considerations for designing wireless remote monitoring applications.

The National Instruments "How-To Guide for Most Common Measurements" is a centralized resource for obtaining information about making common sensor and signal measurements. Each of the following sections covers the operating principle for the corresponding signal/sensor and offers guidance on how to make that measurement. The purpose of this document is to help you get to your measurements quickly.
