M & C LighTIng ’s latest innovation, t''Light E, contains two environmentally friendly desk lamps with a dimmable 5W light-emitting diode (LED) and an Apple-certified USB charging port. Compared to other light sources, LEDs have a longer lifespan, lower power consumption, and no compromise in light quality. t''Light E series is suitable for lighting when reading and working. The fully integrated USB interface is certified by Apple and can charge iPad, iPod and iPhone (including iPhone 5). t''Light E can also charge most other mobile phone and tablet brands that use a USB charging cable. The world ’s third largest stock exchange in Hong Kong recently purchased hundreds of t''Light E, bringing employees the latest products that have both LED lighting and mobile device charging to improve office efficiency.
The aspheric lens uses a single element design, which helps reduce the number of lenses in the optical assembly. Unlike spherical lenses, aspheric lenses have a more complex surface, and the curvature of the surface gradually changes from the center of the lens to the edge of the lens. The most significant advantage is that it can correct the spherical aberration caused by the Spherical Lens in the collimation and focusing system. One of the applications of aspheric lenses includes focusing the output from a laser diode, which not only reduces the overall cost, but also outperforms components designed using traditional spherical optical lenses.
The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. Small molded aspheres are often used for collimating diode lasers.
