Established in 1990, China TianLe Led&light Products Co., Ltd. a professional led array manufacturer and designer of an extensive range of led products, lights, torches, backlights, spotlights, bulbs, lamps and lighting products for indoor and outdoor, domestic and industrial uses. We have recieved both ISO9001 and ISO14001 certification and most of our led arrays are certificated by CE, BS, UL, GS, ROHS, KEMA-KEUR. Moreover, Our QC department employees are able to offer you good device as SGS audit standard.

With this interactive apparatus, you can easily demonstrate that different colors respond to different wavelengths. Eleven LEDs spanning the visual spectrum are arranged and fixed in a durable structure for viewing through a diffraction grating you supply. When viewed in this manner, the LED Array effectively highlights the link between color and wavelength. You can also use the apparatus to explain how LEDs generate light, lead students in calculations of wavelength for any color. The Array features connection points to allow users to measure the voltage across each individual LED. This unique capability allows students to determine Planck's Constant from the data gathered on the voltages and wavelengths of each LED. Using the Array as a tool in Planck's Constant calculations will add an interactive element to the illusive equation, therefore developing a greater understanding. Includes a teacher's guide. 115 VAC.

Animals which are only nocturnally active (whether in their natural habitat or in the laboratory) or which live in dens provide a specific problem for the behavioral observer; namely providing adequate lighting for filming at the site or in the lab without influencing the animal's behavior. This problem can be solved with the new Tracksys Infrared LED array. This compact unit, packaged in a waterproof casing, contains a heat-sunk array of 90 infrared LEDs that generate only negligible visible light. This way the observer will have a good view of the animal, but not the other way around! The software for the VL-10 version allows for full implementation of all the settings of the signalMinder, including the programmable running light intensity and time-out selections. The side view mirrors are the widest points of the motorcycle. Mirror mount location makes your motorcycle look wider and much more conspicuous. VectraLight uses a microprocessor to time the sequencing of the super bright LEDs.
