What Is LM 79 Testing lab and Need & Methods of LM Testing

  Best LM 79 Testing Labs all NABL and BIS Approved lab As the expansion of LED Testing technology continues to fatten and enlarge, the need for compatible and standardized testing procedures for LED has become more ubiquitous than ever. So, IESNA has come with LM 79   Testing Approved Method to measure the electrical, photometric and colorimetric parameters of SSL Products like luminaries, lamps, tube lights, bulbs, flood light, street light, down light, panel light and all types of LED , OLED products. LM Testing Labs 1. Electrical parameters - Current, Voltage, Power Factor, Frequency 2. Photometric parameter- Luminous flux, Efficiency, Light intensity distribution in candela) 3. Colorimetric parameters - CCT, CRI, X Y coordinates LM 79 testing Labs will be performed by recognized Laboratories and the reports issued from such labs are relevant. All NABL and BIS Approved lab for can perform LM 79 testing. The Equipment that is required for LM 79 Testing the INTEGRATING

V ibration testing Lab is accomplished by introducing a forcing function into a structure, usually with some type of shaker. Alternately, a DUT (device under test) is attached to the "table" of a shaker. Vibration testing Labs is performed to examine the response of a device under test (DUT) to a defined vibration environment. The measured response may be ability to function in the vibration environment, fatigue life, resonant frequencies or squeak and rattle sound output (NVH). Squeak and rattle testing is performed with a special type of quiet shaker that produces very low sound levels while under operation. For relatively low frequency forcing (typically less than 100 Hz), servo hydraulic (electro hydraulic) shakers are used. For higher frequencies (typically 5 Hz to 2000 Hz), electrodynamics shakers are used. Vibration Testing laboratory Vibration Testing Lab and Its Process Vibration testing is the process of evaluating the performance or degradation of a product,

 What is Vibration Testing? Vibration testing is the application of mechanical motion to a component, product, system or structure in order to observe its response or degradation over time. Although there is overlap between the two definitions, vibration testing is distinguished from Mechanical Shock Testing by being applied for a longer period of time, ranging from a few minutes to many weeks. Mechanical shock tests have typical durations of less than one second per shock, although multiple shocks over longer time periods are commonly performed. How is Vibration Testing done? The simplest vibration testing procedure, sine vibration testing uses a single sinusoidal tone following simple harmonic motion input to the test specimen. This sinusoidal tone can be swept across the test frequency range, or it can be fixed on a single frequency, depending on the requirement.
