How will the 2010 indoor lighting LED Swordsman
LED lighting industry in the fierce competition, rapid development, the development momentum. As the global economy continues to warming, and China for the continued increase in investment in low carbon industry experienced in 2009 of rest after the 2010 Chinese lighting industry, especially the green lighting industry will usher in a new period of rapid development.
2010, LED lighting will be the performance and cost of war
To build energy-saving environmental protection in the idea of low-carbon economy, China's semiconductor lighting industry is bigger cake. According to the relevant institutional analysis, in 2010, China's industrial output led to more than 150 billion yuan; compared with 2008 output doubled in 2008 of about 70 billion yuan output value.
China is the world's largest producer of lighting and lamps, but the main production of low-end products, accounting for about 18% of the global market share. In the industry chain, led chip led epitaxial wafers with about 70% of the profits of the industry, led application of about 10% -20%; led package, less than 10%.
In the lighting market, led the rapid expansion of light penetration, the market price war is brewing in 2010 broke out. Something to be concerned that, due to lighting led lamps and light sources separately to overturn the traditional sales model, coupled with a high degree of customization, cost pressures in the led lighting manufacturers, under tight pockets, if not deep enough, it will not take into account product quality and price competitiveness, and the fear of falling into the merger or the market is doomed.
Neo-Neon Group General Manager Zheng Jianwen that in 2010 led lighting market is bound to evolve as the cost of the war, especially in the area's crowded main lighting, in which the product performance and price the market will be the key to success is not just copying available .
As the industrial supply company led the development of mature, barriers to entry are not high, it attracted many companies rushed to form a small factories lined the situation. However, unlike the traditional lamp specification has been standardized, can reduce manufacturing costs, led lighting high degree of customization, resulting in capacity utilization is low; In addition, led point light source properties, leading to led lighting to be integrated with the bulbs for sale, increasing the height of LED lamps the cost of business risk. On the other hand, the traditional giant Philips brand lamps (Philips), Osram (Osram) and GE also cater to the market situation, has already competed through vertical integration or strategic alliance with the layout, and actively led occupation of the main lighting market. Whether gross margins at every level of exploitation or much larger rivals, small factories were able to escape the fate of living space squeezed.
Zhengjian Wen pointed out that, led lighting industry supply chain, vendors and more complex than traditional lamps a few large companies, the most downstream of the lamp suppliers to pay the costs will increase, and regardless of lighting design or price are similar, so they can master the product differentiation technology and costs have led companies the opportunity to win. He also emphasized that traditional brand lamp maker has laid pathways, as well as the advantages of a diversified product line are new entrants or smaller can never be led beyond the lighting industry, once large and powerful style of playing the price of the lamp maker war, small factories would be difficult to survive.

How to set up basic knob/button operated LED light?
I am building a model of a hockey rink. I want to rig up a very simple knob operated red LED light as the goal light. I would like to have a battery hooked up all the time and be able to use the knob to flick the light on/off. If it makes a difference, the LED light will be red. I also hope to have the wire from the LED light to the knob be about 7 feet.
Through research so far it seems as simple as connecting(with solder and wire) the battery piece to the knob to the resister and finally to the light.
Any advice or if someone could point me to other resources would be greatly appreciated. Thank you in advance.
yes it's that simple, the only problem is if you don't have the led hooked to the +/- wire properly with respect to polarity. one lead (on the led) should be longer, that one should be hooked up to the + side, if you get this wrong, don't worry you won't damage the led, just switch the leads
this is really the big difference from a bulb, as a diode an led will only allow current to flow in one direction, whereas a light bulb can be hooked up to either terminal and will still work, an led has a positive side and a negative side
