Tips for us how to use LED Flat Panel Light fixture

When bought some led flat panel lights, we should know how to use them correctly. Only by right usage steps, led flat panel light could be maintained and used for a long time. Now, professionals will give us some useful tips on using led flat panel correctly as below:

The first step before you use led panel light is to installation. Don't install led panel light on pin deformation condition. When you are installing it on printing circuit board, you had better keep the same distance between the hole centre of circuit board and the foot centre spacing of led panel light. Because the hole spacing is so wider that welding distortion. When you plug led panel light into PCB board, the hole of PCB board should be made to match the size of led panel light in case of too big or too small. It is recommended to use guide sleeve positioning when installing. You should choose the size of welding pad in according with the type of your led panel light. For double welding pin, each foot of welding pad occupies the area of not less than 4.6 square millimeters. For SMD bracket, each foot of welding plate occupies the area of not less than 1.65 square millimeters. When it comes to welding, you should consider the suitable temperature and time. Please reduce the shock the welding stress to the chip of led thermal to a minimum. Please don't be charged while welding.

When you use led panel light, you must focus on its working condition. The driving current of working should not exceed the maximum current wrote in the specification. It is advised that the drive current keeps between 10 to 20 MA. The ideal temperature of working is negative five to zero. However, it is impossible. Therefore, you had better put a small fan aside the led panel light to disperse the heat, so that it can prolong it lifetime of using.

At the same time, you also should pay attention to the polarity of led panel light. Generally speaking, the longer end of light foot is for positive, while short one is for negative. You should identify carefully if the lame feet are the same long. Don't make heat resistance components close to led panel light as far as possible. Please avoid friction with hard objects such as metals.

In a word, you should know more about the characteristics of your led flat panel light as much as possible, so that you can take reasonable measures of protection when you are using it.

Anchor to Expand LED Lighting Business and Begin Manufacturing in India

Anchor Electricals, a subsidiary of Panasonic India, is reportedly looking to expand its LED lighting business. Last week the company opened an LED lighting experience center in Mumbai and announced plans for a similar center in Bangalore."Our next such showroom will be in Bangalore and we will continue expanding to other major cities in India and hope to increase to 1,000 stores, including distributor and dealer stores, by around FY 2014-15," Anchor Electricals vice president sales Ashok Gangar said. "We will open four distributor stores in Mumbai and gradually spread out to other main urban areas." Gangar further stated that Anchor would soon select a site for a new plant to manufacture LEDs in India, however, he refused to share the details of the location.

Panasonic acquired Anchor, the 49-year-old Indian family-owned electrical equipment brand, in 2007. Anchor sells products like switches, fans, CFL and LEDs and also sells switches under the Panasonic brand, which are priced slightly higher.

"By March next year our turnover would be Rs 2,100 crore and it has almost doubled. In 2007, when Panasonic acquired it, the turnover was around Rs 1,000 crore," he said, adding that it has remained in number one atop the electrical switch gear industry. Currently, 55 percent of the company's revenue comes from this business segment, Gangar noted.

Although, presently the company does not export, Ganger revealed the company has plans to export in next two years to Gulf and Africa. "Till now there is no export from us. But in last few years, changes have happened. Our quality has improved as new technologies are coming from Japan. In next two years, we would start exporting our products to Middle East and Africa under Anchor by Panasonic brand."

2016 Summer Olympic and Paralympic Headquarters Incorporates Energy- and Maintenance-Saving GE LED Fixtures

So don't plan on having that monitor added to your gaming system unless you have lots of money to spend.

Samsung to Switch Flash LED Package Specs to 2016

Smartphones are driving up demands for flash LED. Aside from Philips Lumileds, Cree, Osram and other leading global manufacturers in the flash market, Taiwanese and Korean manufacturers are also entering the market. Samsung plans to switchits flash LED package specs from 4139 to 2016. Following various manufacturers  production launch, industry insiders estimate larger price cuts for flash LEDs in 1Q14.

For flash LEDs to emit light, it requires high currents in a very short period of time.    In smartphone applications, the size of the flash LED must also accommodate available space. Following smartphone camera specs upgrades; flash LED brightness has also increased, going from 75 lm to 500 lm. The industry believes that the main 2016 specs for flash LEDs will be extended into 2014, and overall brightness and current voltage will also continue its upward climb.

The global flash LED market is still largely led by Philips Lumileds, Cree, and Osram. Following smartphone flash LED upgrade to dual-flash, the industry anticipates continued growth for flash LED. Taiwanese manufacturers including chip manufacturer Genesis Photonics, package manufacturers Everlight and LiteOn Technology are all aiming to enter into the flash LED supply chain. Everlight has already snatched a hefty market share since its product entry into  China’s smartphone supply chain. Samsung, which previously used in-house package specs, is also taking into consideration its export market, and planning a major shift into the2016 LED market.

As far as flash LED specs are concerned, 2016 is the main spec used in smartphone flash applications. Previously, Samsung mostly used 4139 LED combined with LED package components, optical reflectors, and second optic lens. In smartphone applications, 4139 LED requires more space due to its larger size compared to 2016. Therefore, aside from Samsung smartphones applications 4139 is rarely used in smartphones. 

Samsung is planning to expand flash LED exports, and hopes to switch to 2016 specs, according to LEDinside understanding. With more  manufacturers entering the flash LED market, industry insiders believe that the current price for a single flash LED unit will continue to drop from US $0.25. It is projected flash LED prices slides will escalate in 1Q14.

Everlight Flash LED Breaks Into Japanese Smartphone Supply Chain

Dual-LED Flash is hoped to become a trend in smartphone application. Taiwan LED manufacturer Genesis Photonics and Everlight have both recently announced their entry into the Japanese smartphone supply chain. LED package manufacturer Everlight, which already has a strong Taiwan, China, Europe, and North America client base, has announced once again its entry into the Japanese smartphone flash LED supply chain . Flash LED designs will feature both warm white and white lights.

Following Apple iPhone5 incorporation of flash LEDs in their design, dual-LED flash is hoped to become a trend. After Taiwanese LED chip manufacturer Genesis Photonics introduced flip-chip technology into the Japanese smartphone flash supply chain, Everlight announced its entry into the supply chain as well. Everlight will use both white and warm white based lights for the flash LED design.

In regards to Everlight’s revenue distribution, the largest portion is made up by backlight products and lighting products at 25 percent each and SMD products which have dropped down to 30 percent. Application in consumer electronics is categorized in the SMD product line. Additionally, infrared ray products make up 15 percent and other products make up the last 5 percent.

TI Floating Switch Architecture Transforms Offline LED Drive Design

Texas Instruments introduced the industry's first floating switch architecture that simplifies the offline linear drive of LEDs in lamps, downlights and fixtures. The AC switched matrix technique features TI's TPS92411 floating MOSFET switch and is an innovative approach to producing low-ripple LED drive current without magnetic components. The architecture provides excellent compatibility with legacy wall dimmers and delivers high power factor and low total harmonic distortion (THD). For more information, samples and evaluation modules, visit www.ti.com/tps92411-pr.

Texas Instruments (TI) new floating switch architecture. (LEDinside/ Texas Instruments)

Flyback, buck and boost converters are common switch-mode power supply (SMPS) topologies in LED lamps today. These circuits operate at high frequencies and require inductive components to turn mains AC current into the constant DC current necessary to drive LEDs. Selection of inductors and transformers for power transfer is complicated, often requiring expensive custom components. In addition, an electromagnetic interference (EMI) filter consisting of four to ten passive components is required to prevent the SMPS circuit from harming other electronic equipment. If phase dimming is required, multiple design iterations may be necessary to optimize dimmer compatibility and prevent LED flicker.

The floating switch architecture with TI's TPS92411 overcomes these challenges. It requires no inductive components for power transfer, eliminating cost and bulk and simplifying design. 

Key features and benefits of TPS92411:

• 100-V, 2-Ohm floating MOSFET switch with 350 mA of current capability
• LED drive performance is comparable to traditional flyback, buck and boost converters:
• Greater than 0.95 power factor.
• Less than 15 percent of total harmonic distortion.
• Low LED current ripple results in efficient LED utilization as compared with "tapped linear" drivers.
• Low-frequency, slew-rate controlled switch action produces very little EMI noise.
• Unlike designs using traditional converters, the very low-cost floating switch architecture requires no inductive components.
• Works well with both TRIAC and reverse phase wall dimmers.
• Supports lighting designs up to 70 W.
• Availability, packaging and pricing

Characterized and binned at 85°C, the new LEDs are available in ANSI White and EasyWhite® color temperatures (2700K – 5000K). Cree claims that the new LEDs provide the industry’s best color consistency for designs that use only one LED. Cree also says that the CXA3590 LED Array is the ideal light source to replace 250-watt metal halide (MH) fixtures. According to Cree, the CXA3590 uses 40 percent less power and is designed to last twice as long as 250-watt metal halide fixtures.

“We are excited that Cree is extending the CXA family because it enables us to address more applications with a single, easy-to-use platform,” said David Lin, general manager, YAH JUANG Lighting Technology. “The CXA3590 LEDs allow us to address high-lumen applications with a single LED, a feat which would have taken hundreds of other LEDs to accomplish.”
“Cree CXA LED Arrays set the industry standard for integrated arrays, providing excellent efficacy, reliability and light output,” said David Gershaw, president, RemPhos Technologies LLC. “The high-performance CXA3070 LED Array enables us to offer metal halide replacements that exceed the efficiency and life of the technology they replace.”

Cree® XLamp CXA3590 and CXA3070 LED samples are available now and production quantities are available with standard lead times.

The advantages and disadvantages of LED household lighting

As incandescent lamps phasing out gradually, LED lighting will inevitably occupy a larger share in the future market with its superiority. It is the inevitable result of the development of times for LED lighting flowing into the houses of ordinary people. However, as for the current market situation, the energy-saving lamp still occupies a large market share in household lighting and its market share is still higher than that of LED lighting. Ordinary energy-saving lamp is still the choice of the general public, while LED lamp is still relatively less.

 

As we all know, compared with the ordinary energy-saving lamp, LED lighting has a lot of advantages: first, energy saving. The brightness of a one-watt LED light is equivalent to an energy-saving lamp of 2 watts. Continuing to use a 5 watts LED lamp for 1000 hours consumes 5 KWH; second, long lifespan. The lifespan of a LED lamp could reach 50,000 hours; third, good applicability. Due to the fact that a single LED is very small in size, it can be made into any shape; fourth, quick in response. The response time used for LED lamp is ns (nanosecond), while for ordinary lamp is ms (milliseconds); fifth, environmental friendly. LED lamp produces no hazardous metal and its waste is easy to recycle; sixth, its color is very attractive. With pure luminous color and narrow spectral rang, the color of LED lamp can be made in mixing color or natural white by mixing the three primary colors: red, green and blue.

 

Although LED lamp has many advantages compared with traditional energy-saving lamp, there are still many disadvantages, such as its price, quality of products and the establishment of brand. To enter the house of ordinary people, LED lamp should foster its strong points and circumvent its weakness to make people willing to accept.
