Led Pulse

Some difference from Common tube and Led tube

Some difference from Common tube and Led tube

1、 Common tube
Each end of a filament lamp, the lamp is filled with traces of argon and mercury vapor thin, tube wall coated with fluorescent powder, the gas between the two conductive filament when the ultraviolet light, so that a soft phosphor visible. 

Working features of the common fluorescent: when it start working ,it need a high voltage and it only allowed to pass small current while the voltage on the tube itself is lower then each end . Both ends of the filament with fluorescent tubes, glass tube wall coated with a layer of thin uniform fluorescent powder, the tube was pumped into vacuum of 10-3-10-4 mm Hg after a small amount of inert gas filled, but also into the trace liquid mercury. Ballast is an iron-core inductor coil, the nature of the inductor current in the coil changes, caused by magnetic flux in the coil will change, resulting in induced electromotive force in the direction of current in the opposite direction, thereby preventing the current changes.   Starter switch from the role in the circuit, which consists of a neon discharge tube in parallel with a capacitor made of the role of capacitance on the power to eliminate electromagnetic interference and the formation of oscillation loop with ballast to increase the starting pulse voltage amplitude. Discharge of an electrode composed of double-metal, the use of neon bulb discharge heating, double metal in the open and close, causing the current mutation of ballast added to the tube and produce high-voltage pulse ends.   When the lamp access circuit after the starter began to glow discharge between two electrodes, so that thermal expansion of two-metal contact with the very touch of static, so the power supply, ballast, and starter filament form a closed loop, the current the filament preheating, when the heating time of 1-3 seconds, the starter of the glow discharge between two electrodes off, followed by double metal cooling off with a very quiet touch, disconnect the moment when the two electrodes , current in the circuit suddenly disappeared, so the ballast to produce a high-voltage pulse, which overlapped with the power supply, added to the tube ends so that the inert gas ionization inside the tube caused by arc discharge, glow in the normal course of ballast self-inductance device also plays a role in stabilizing the current in the circuit. 2 .Led tube   Led tube with high quality, durable, energy-saving as the main characteristics of the projection angle adjustment range, 15W brightness equivalent to an ordinary 40W led tube . High temperature, moisture and waterproof, leakproof. Use voltage: 110V, 220V optional, jacket optional glass or PC material. As with ordinary fluorescent lamp.   LED ltube light source is using the latest technology, digital design, saving up to 70% or more, 12W of LED fluorescent light intensity equivalent to 40W fluorescent tube (used for ballast and starter, 36W fluorescent real consumption Electricity for 42W to 44W). LED fluorescent lamp life of more than 10 times normal, almost maintenance-free, no need to frequently replace the lamp, ballast and starter. Green semiconductor light source, light and soft, pure spectrum is conducive to protection of the user's eyesight and physical health. 6000K cold light source gives the feeling of cool visual, user-friendly design of the illumination differences, but also help to focus and improve efficiency.   Currently, compare with LED tube and common fluorescent tube , the advantages are as follows:   1. Energy-saving . 2. long life . 3. Good applicability, because the size of a small single LED can be made into any shape. 4. Response time is short, is ns (nanosecond) level of response time, and general lighting is ms (millisecond) response time levels. 5. Environmental protection, no harmful metals, waste easier to recycle. 6. Colorful, luminous, pure color, a narrow spectral range, and through the red, green and blue color blending into a colorful or white.   Disadvantages: 1. Expensive.  2. Currently able to do general theory of optical efficiency and the efficiency of light there is a big gap.  3. At present the life and theory life (10w hours) there is a big distance 4. Still have some heat. 5. Light failure can be greatly reduced.   However, these shortcomings can be overcome by process improvements, so even if the current LED light source can not completely replace the existing traditional sources, but with the technology, the future of the world must be LED tube

Pulse - $8.99 Television commercial director and music video maker Marcus Adams directs the U.K. thriller Octane, shot entirely in Luxembourg. Madeleine Stowe stars as overprotective mother Senga Wilson, who doesn't want her teenage daughter Nat (Mischa Barton) to get into trouble. While driving down the road with her mother one night, Nat jumps out of the car and escapes with a bunch of backpackers. It turns out the crowd she's running with is really an evil cult that's out for blood, led by a freaky guy they call The Father (Jonathan Rhys Meyers). In order to save her daughter, Senga embarks on a thrilling journey into a rave/dance underworld of violent twentysomethings while she copes with her own past. The techno soundtrack was provided by Orbital. Octane premiered in the U.S. at the 2003 CineVegas International Film Festival and was renamed Pulse for its eventual video release. ~ Andrea LeVasseur, Rovi
