Indoor LED lighting market hinder the rise of three threshold

The largest LED lighting market is LCDTV and phone LED backlight, followed by LED lights, and then followed by the building facades, interior decorative lighting and roads. LED lighting market is the second major development trend of solar power were dimming.

LED lights the future, whether or indoor LED lighting market, there is no dimming function is not sell the product. Of course, this will as Zigbee and other proprietary wireless technology to bring additional remote control market.

Solar-powered LED lighting products for the following three markets: the parking lot lighting, interior lighting, and lawn. Light Speed Avnet company director Cary Eskow said: "If we can produce cheap solar-powered LED lighting products, then we open up at least in Africa, a big market."

Of course, the most simple solar-powered LED lighting products need only four components: solar cell array, rechargeable batteries, Schottky diodes and high brightness LED. Diode to prevent current flowing back at the battery back to solar cell arrays. But such a system difficult to achieve high efficiency, because the solar cell current and voltage output characteristic is nonlinear. To improve the efficiency, we must use to as MPPT (Maximum Power Point Tracker) technology. Due to limited space, this article will not go into, interested readers may refer to Articles published in another website about a feature report: "Improving the efficiency of solar-powered LED lighting method."

However, the growth potential and room for the largest indoor LED lighting market is also developing very slowly, although the reasons for this situation there are many, but CaryEskow said: "The three most important impediments or challenges are difficult thermal design, high cost and supply market immaturity. "

He said the interior LED lighting system design encounter the biggest challenge is how to cheap, energy-saving and effective method of heat dispersion LED chips sent out.

Outdoor LED lighting is different, interior LED lighting in a closed environment with poor ventilation, even if you use the LED chip cooling aluminum plate of tropical out of this heat also can not be dissipated. Unless you use the fan to dissipate the heat, but this is one of the most terrible and worth the solution, because the power required to drive the fan motor may have more than you want to save by switching to LED and power. Heat pipe solutions have the same problem, but also increase the cost of many.

Cary Eskow said: "Today's really quiet, effective and energy to achieve top-style LED spotlight embedded solutions for the cooling effect is only Nuventix revolutionary active cooling solution, it does not need the fan, but as the speaker of the diaphragm can cause the same flow movement to reject heat. It is currently on the market to solve the challenges the next generation of indoor LED lighting heat the best solution. "

Today, from the LED stage lighting to industrial and domestic top-style LED lighting applications embedded high-brightness, high power LED products LED cooling demand has created can not simply use a LED heat sink to solve their heat problem. Passive cooling methods can not meet the needs of LED general lighting design, such as the radiator using only the words of a single, high-brightness LED will become too hot. However, the large lumen LED lighting applications in the power of Syn Jet by Nuventix patented heat quickly.

Nuventix at a reasonable price by providing a quiet, reliable, highly flexible non-fan air flow device (it can be effective, direct and efficient heat dissipation), is brought into active thermal management technology a revolutionary advancement . The patented SynJet cooling solutions can be integrated to any little LED lighting devices anywhere, thermal issues. You no longer need large cooling fan noise or heavy aluminum radiator-based design.

Technology-based SynJet active cooling solutions can provide effective cooling, high reliability and quiet sound levels similar to, and no restrictions on form factor. Use SynJet LED cooler thermal management solutions can generate double or even triple lumen output, while maintaining the same form factor and the same acceptable low temperature. SynJet pulse can produce Chuanji air flow, which can bring a better than fan cooling efficiency and effectiveness, while there is no noise.

Over the years, active cooling has been limited by the traditional tools of air flow: fan. With SynJet technology today, designers can enjoy the benefits of active cooling methods (such as high lumen output, smaller heat sink, more unique design and shape factor, etc.), but not the traditional air-flow device (such as fans) bring any deficiencies. Today's active cooling solution is no longer limited by the reliability of gas flow, the noise problem has been resolved.

The high cost of LED indoor LED general lighting market hindered off the second major factor. Avnet China Business Development Director Zhongjin Hong said that the current produced by the LED chip is mainly used to meet the LEDTV and phone / notebook backlighting market demand for LED general lighting market are now in short supply status LED chips, LED chips, whether production or the packaging showed a lack of state capacity. However, Zhong Jinhong said: "In fact, compared to previous years, LED chip prices have been reduced a lot in the future market demand will continue to go down after. Any one emerging market are such a trend. "

Cary Eskow said that as a distributor, we can not simply his own power to solve the cost problem, but we can do is to present the LED chips in the price basis, providing customers with higher value of LED lighting solution programs, such as higher efficiency, higher reliability, lower power consumption and lower maintenance costs.

However, he also said: "printable OLED made to resolve the future could become the ultimate cost is now LED-chip solution, its manufacturing method determines the mass production of its lower cost. OLED flexible and can be made planar light, which makes it real for the office or home to provide a uniform surface illumination, which is the indoor places such as offices and restaurants common point intensive Distributed LED lighting can not. In addition, the cost to buy it , installation costs and maintenance costs than the current socket type (socket) LED is much lower. "

OLED current problem is still not produce high-brightness light, so in the future for a long period of time, the two LED general lighting complementary manner, in coexistence. Cary Eskow added.

The third factor is the major obstacle to the supply market itself immature. At present a lot of competition for this market, the company itself did not have the technical capacity and knowledge, because a successful indoor LED general lighting design involves mechanics, optics, electronics and thermal expertise in four areas. The company disrupted the market order, making it difficult a time to grow up healthy.
