Manufacturers of LED based products ranging from general lighting to niche products such as bicycle lamps and headlamps require various measurement capabilities to ensure product performance and quality.
For example, the tolerance classifications in LED binning often exceed those permitted by the application or do not match the end use operating conditions thereby requiring device testing and selection. Therefore, manufacturers benefit from versatile, cost effective and accurate light meters that meet the differing measurement requirements of product development, goods-in inspection and testing of single LEDs, measurement of assembled LED arrays and single LEDs, as well as quality control of the final products.
The Plus concept for flexible use of the BTS256-LED
The BTS256-LED Plus concept is based on the BTS256-LED, a compact spectral light meter that can be used to measure the luminous flux, spectrum, color, and color rendering index of LEDs. One key feature of the BTS256-LED is its conical measurement port that makes it possible to perform measurements of assembled single LEDs even within array formats.
With the optional accessories, the range of functions of the BTS256-LED device can be easily enhanced to suit different applications. One distinguishing feature of this spectroradiometer is its precision bayonet socket for attaching accessory equipment. This eliminates the need for connecting light guides which avoids the common reproducibility problems experienced when connecting and disconnecting light guides and thereby maintains traceable calibration.
