LED makers in China plan to add numerous MOCVD systems in 2011

Mitsui and Unity Opto are to invest in Forepi, LED makers in China plan to add numerous MOCVD systems in 2011, Epistar is making a further investment in its China-based JV, and Tyntek is also expanding.

Mitsui and Unity Opto to invest in Forepi

Mitsui & Co., Ltd., a major Japan-based industrial conglomerate, is to become the largest shareholder in Taiwan-based LED wafer and chip maker Formosa Epitaxy Inc (Forepi). Mitsui will invest around NT$2.7 billion (approximately JPY7.6 billion) to acquire 15% of Forepi as part of an upcoming private placement of 90 million shares at a price of NT$36.44 per share.

Founded in 1999, Forepi is the second-largest LED epitaxy and chip manufacturer in Taiwan and has plants in Taoyuan, Taiwan and Yangshou, Jingu province, China. Mitsui says the deal is part of its aim to “create new value by consolidating the resources along the LED supply chain.” As well as having a network of shops selling LCD TVs and monitors, Mitsui has held a 16% stake in AOC International, one of the world’s leading monitor makers.

A Taiwan Economic News article says that, in addition to the Mitsui deal, Unity Opto Corp. will purchase 15.3 million shares in Forepi for an investment of US$18.6 million. Unity is a leading LED packager in Taiwan, and the deal will help to secure a steady source of LED chips for its backlight packages used in various applications, including TVs, computer monitors and tablet PCs. Also, the company has begun introducing LED packages for general lighting.

China LED makers to add MOCVD systems in 2011

China's LED industry is expected to install 700-800 MOCVD systems in 2011 compared with 330 units installed in 2010, according to a report on www.digitimes.com. This trend is likely to enable China's LED industry to catch up with Taiwan in terms of MOCVD production capacity.

The report also suggested that one China-based LED maker has given an order for somewhere between 400 and 500 MOCVD machines to Germany-based Aixtron. If this is true (Aixtron didn’t comment but its share price rose rapidly after the report came out) then delivery lead times will be greatly extended.

The report says that Sanan Optoelectronics is currently the largest LED-chip maker in China. The company apparently had a total of 40 MOCVD machines at the end of 2010 and will expand this to 100 units in 2011. The current second- and third-largest chip makers, Xiamen Changelight and Inspur Huaguang Optoelectronics, are expected to each have around 30 machines by the end of 2011.

Epistar invests further in China JV

Epistar Corp., Taiwan’s largest LED chipmaker, is to invest an additional US$19.5 million in United LED Shan Dong Corp, a joint venture established in mainland China with United Microelectronics Corp. This will push Epistar’s investment in the Chinese joint venture to a total of US$27.5 million, with its stakeholding increasing to 55 percent from 50 percent, according to an article in the Taipei Times.

The same article quoted an analyst company, which is forecasting that Epistar’s sales will grow by 25 percent to 30 percent year-on-year in 2011, after experiencing weakening demand and falling prices in the final quarter of 2010.

Tyntek expands in China and Taiwan

Taiwan-based LED maker Tyntek plans to invest CNY153 million (US$23 million) to set up an LED production joint venture with the Fuzhou government in China, according to an article on the Digitimes website. The first phase of development will focus on LED epitaxy and chip production, and around 30 MOCVD systems could be installed eventually. Production is scheduled to commence at the end of the third quarter at the earliest.

The article also says that Tyntek will install a further 10-15 MOCVD machines at its Taichung, Taiwan facility in the second and third quarters of 2011.

LED lighting market expected to compete more intensify with its price dropping

The market estimated that LED lighting products' prices would drop by 15-20% each year amid increase competition in the market as vendors reduce prices to gain market share, which even be fall to one-third of current prices.

At first, the Japanese market appeared to price war in 2009. Sources from LED companies indicated that the price competition had extended to China, Europe and the US.

Some light bulb makers reportedly would introduce LED lighting products at end-use price of US$10 in 2011, which would compete for pricing scheduled to enter the LED sector with distributors and retailers well-known, and the price battle would only intensify in the future.

Toshiba LED Mini Bulb Exploded Diagram

We have exploded several types of LED lamps (E27, MR16, GU10, Par30) in a series of articles, illustrating some interesting renderings. Now in this post, we will demonstrate some real stuffs – an exploded Toshiba LED mini bulb.

Toshiba LED Mini Bulbs

This is what a 3.4W Toshib LED mini bulb looks like before being exploed.

Toshiba LED Light Bulbs - Lamp Cover

This is the lamp cover of a Toshiba LED bulb. This is a translucent lamp cover, neither transparent nor frosted lamp cover. The LED in the lamp can be seen from outside the lamp through the translucent cover.

Toshiba Mini LED Bulbs - Module LED

Toshiba LED Light Bulbs - Exploded 01

Now, the mini bulb has been exploded. We can see very clearly, a module LED (about 3W) is on the center of a PCB with aluminum plate (for heat dissipating). Judging from the LED’s colour, this is probably a warm white LED bulb. The PCB is quite simple, but we still find two electric wires are connected to something in the lamp body.

Toshiba LED Light Bulbs - Exploded 02

From this photo, the body of the light bulb can be seen right through. And finally, the secret of the two wires has been revealed. The wires are connected to the driver. The driver is basically some electronic components integrated on a PCB. We have explained that in our previous articles that when LEDs work, they usually need some drivers as they can not be driven by AC current directly. However, in fact, this conclusion is only applied to DC LEDs. There is another type of LEDs which is AC-driven LEDs which can be driven by AC current.

Above is how we exploded a Toshiba LED mini bulb.

Apple Booked Epistar's LED Backlights for iPad

Reportedly, Taiwan LED maker Epistar has acquired Apple's order for LED backlights for use in iPad.

Benefiting from increasing LED applications in TV, notebook PCs and lightings, Epistar confirmed that its production lines have been fully booked by contract orders till this June. This secures the firm strong growth momentum in sales and shipments in the first half of 2011.

Diagrams of Typical LED Par Lamps: Par30

Continuing with our last post "Diagrams of Typical LED Spotlights: GU10" regarding GU10 LED spotlights, in this post, we will talk about LED Par30 Lamps.

LED Par30 Lamps

Traditional Par lamps are commonly used in stage ligting applications. Par lamps are used to illuminate the stages, with dynamic-changing light colour, they are common lighting fixtures on the stage. However, because of the high power consumption, Par lamps are now gradually being replaced by LED PAR lamps. LED Par Lamps are designed to replace traditional halogen Par lamps. 5W LED to replace 40W halogon, 7W LED to replace 50W halogen, 9W LED to replace 60W halogen, 12W to replace 75W halogen, 80-90% energy saving. See Fg. LED Par30 Lamps.

From the appearance point of view, LED Par lamps and traditional halogen Par lamps look very similar. However, in fact, the difference between them is tremendous.

Light Source: light source is the essential difference between LED Par lamps and halogen Par lamps, and that's the reason why LED lights are much more efficient than halogen lamps. halogen lamps generate light by heating tungsten that covered by halogen gas, while for LEDs, simply describing, when current goes through LEDs, compounded particles in P-N junctions will then release photons (energy). LEDs generate less heat when emitting light, that's the reason why LEDs are much more efficient than halogen lamps and incandescent bulbs.

LED Par30 Lamps - Dimension

Materials: materials are different, LED Par lamps usually need aluminum heatsink for heat dissipation while halogen Par lamps do not - their lamp bodies are usually made of plastic.

Driver: furthermore, LED par lamps need drivers (or transformers) in order to be running in existing GU10 fittings, normally 110V or 240V high-voltage fittings.

The picture below illustrates a typical LED Par30 lamp's exploded view. The Par30 lamp is decomposed into 9 components as can be seen from the diagram. Following are the corresponding annotations.

Various standard LED lampholders: E27, MR16, GU10, PAR

According to installation, lampholders are generally divided into bayonet-type and screw, etc. According to material, bakelite, lamp holders are made of plastic, metal, ceramics, etc. For example, E27 maybe the most commonly used screw lampholder for light bulbs. And the lampholders for fluorescent and energy-saving tubes are referred to as T8 and T5.

Some lampholders may require up to IP68 protection grading. Usually lampholder are required to meet IEC (International Electrotechnical Commission standard) security certification.

Lampholder Classification:

Typically, the name of a lampholder type is likely to be like this “letter(s) + number(s)”. A letter at the beginning often indicates the shape of the bulb, i.e. E for Edison, T for tubular, R for reflector.

E12, E14, E26, E27, E40 and other names with “E” at the begining are all Edison screw lampholders. Obviously, E represents Edison, the name of the great man who invented incandescent bulb. E27 is commonly used in residential lighting – incandescent light bulbs. E14 has a smaller size than E27, while E40 is larger than E27.

B22, with 2-pin screw, is another commonly used lampholder type for incandescent light bulbs.

GU lamps (e.g., GU10) is a daily use bayonet-type. GU: G type lamp holder, said plug-in, U said that U-shaped lamp part of the show, behind the numbers that light foot hole center distance (in “mm”) .

MR16, MR11 lamps. Begining with “MR”, followed by a number, this type of lamps are usually used as spot lighting for a small area. The lamps usually have two small pins. MR: Multiface Reflect, multi-faceted reflector (light cup), followed by numbers indicates the lamp cup diameter(unit is 1/8 inch). E.g., MR16′s diameter = 16 × 1/8 = 2 inches or = 50mm. The same calculation for MR11.

PAR lamps are generally PAR20 PAR30 PAR36 PAR46 PAR56, volume may be long or short, also known as down light, light beam, used to illuminate the stage, dynamic change color, are common fixtures on the stage, because the relatively large power consumption, but also grilled Feeling, now gradually being replaced by LED PAR lamps.Dimension is increasing as the number following “PAR” increases, i.e., PAR38 has a larger size than that of PAR30′s.

City of Novato Testing LED Street Lights

It's reported that city of Novato is in the process of conducting a LED street light test to gain public feedback on its selection of energy-efficient lighting fixtures.
Four LED lighting fixtures have been installed between Rowland Boulevard and Adele Drive, and four induction fixtures were installed between Arthur Drive and Yukon Way.

All lights installed are expected to reduce monthly electricity costs by about 40% and also reduce routine maintenance costs three to four times that of the current fixtures.

Taiwan LED Industry May Keep on Steady Growth in 2011

Taiwan Photonics Industry and Technology Development Association (PIDA) has recently predicted that the local LED industry will grow at a moderate pace in 2011.

According to PIDA , the output value of the global LED industry grew an increase of 68 percent from US$9 billion in 2009 to US$15.1 billion in 2010, and the number will further increase by 38 percent to US$20.8 billion in 2011.

Lu Shao-hsu, a PIDA analyst ,pointed out that Taiwan's output value of LED packaging and modules, which rose nearly 60 percent in 2010, is expected to increase only 24 percent in 2011 due to a higher base period comparison.

Deaphne Kuo, another PIDA analyst, also estimated that the global output value of large backlights, including applications for televisions and notebooks may approach US$7.3 billion in 2012 from an estimated US$2.98 billion in 2010.

Furthermore, based on technological improvements and the support of governments, LED lighting will become another factor driving the entire LED industry around the world, Kuo added.

City of Foley Considers Retrofitting LED Lights

It's reported that City of Foley is thinking about updating some new light throughout the city by experimenting with Led technology.

On Monday, Bravo Zulu, a technology company specializing in communications and monitoring technology have given a presentation focused on the benefits led light technology could have for the city, and ways the technology could be implemented to the city council.

According to Bravo Zulu , one of the main benefits of its LED technology is an included sensor system, which detects motion to turn the lights on when cars or people are nearby and dims the lights, using less power when no one is nearby.
So far, no decision has been made regarding the placement of LED lights in Foley, but the council is considering the possibility.

LED Light Underware, Would You Put That ON？

If I asked you, what can led lights be used for? I’m sure you’ll know the “standard answer”, which would be “led lights can be used for lighting”. Yes, I can not say that you are wrong, but I’m afraid with this answer, you could probably get an B (maybe B+, if you are lucky enough), but you would not get an A from me. Wondering why?

I always believe that, imagination is the greatest gift for mankind. Great imagination creates great things.

In this article, let our brilliant designers lead you into a dream world. These talented designers would let you know that lights are not only for decoration of buildings but are also capable of decorating human bodies, lights are not only lights, they can be clothes too. The following are some LED light clothes.

China May Come out the Restrictions to Phase out Incandescent Light Bulbs

After the EU, the US, Australia and others have imposed restrictions to phase out incandescent light bulbs, it's reported that China is in the process of making the road map for banning the use of these bulbs. The restriction is expected to be unveiled in March.

According to Wang Jinsui, director general of China Illuminating Engineering Society, said in China Business News," The National Development and Reform Commission has been drafting the map."

Wang said the initial plan is to stop producing 100-watt incandescent bulbs after 2015 and ban them completely from 2018. China has provided subsidies for using energy-saving light bulbs since 2008, prompting many incandescent bulb producers to cut their output.

LED E27 Light Bulbs

From the appearance point of view,  globe LED light bulbs and traditional incandescent bulbs look very similar. However, in fact, the difference between them is tremendous.

Globe LED Light Bulbs E27

Light Source: light source is the essential difference between LED light bulbs and traditional incandescent bulbs, and that’s the reason why LED lights are much more efficient than incandescents. Rather than using tungsten wires, LED light bulbs adopt LEDs (Lighting-emitting Diode) as light source.

Materials: materials are different, LED Light bulbs usually adopt mist glass and aluminum, while incandecents usually adopt transparent glass and plastic. Reasons for that: LEDs emit very strong directional light (spot light), with transparent glass, the light would be too harsh to make people feel uncomfortable.  Therefore, it needs diffusion treatment – defused lens.

Driver: furthermore, LED light bulbs need drivers (or transformers) in order to be running in 110V or 240V high-voltage fittings, while the traditional incandescent light bulbs do not.

The picture below illustrates a typical globe LED light bulb exploded view. The light bulb is decomposed into 9 parts as can be seen from the diagram. The following are the corresponding annotations.

Do you know broken energy-saving lamps harms?

Nowadays, energy-saving lamps are increasingly replacing the traditional incandescent light bulbs, and become the most environmentally friendly lighting choice. To achieve their emission reduction targets, the EU is to phase out traditional incandescent that has been used for 120 years. People are mandatory  to replace their low-efficiency light bulbs with energy-saving lamps. In the UK, compact fluorescent (CFL) is the most common energy-saving lamps. Germany, however, warns the public based on a new study: the mercury released by broken energy saving lamps will be a risk to health, especially for infants and young children and pregnant women. While, LED lights, traditional incandescents, and halogen light bulbs will not cause such problems when broken, because they do not contain mercury.

German Federal Environment Agency claimed that, according to the new research, the mercury toxity of broken energy-saving lamps can be 20 times excess of interior safty guidelines’ standards. GFEA’s Board Secretary said that the presence of mercury in CFL energy-saving lamps is a major defect, therefore, new technologies are need to be adopted as soon as possible to prevent mercury pollution.  The advantage of 80% energy saving and safty of CFLs ought to be synchronous development. A council spokesman said that children and pregnant women should stay away from broken CFLs. In those places with children and pregnant women activities, protection lampshades are suggested to be installed to prevent mercury release by broken energy-saving lamps.

However, the British government insisted that the mercury risks of energy-saving lamps is over-concerned. Broken CFL bulb mercury hazard in fact is some occasional cases, not a big deal. UK Department for Environment, Food and Rural Affairs spokesman claimed that, the mercury containing in the CFL energy saving light bulbs is insufficient of harming the surrounding populations.
