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.

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.

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.

Diagrams of Typical LED Spotlights: GU10

Continuing with our last post” Diagrams of Typical LED Light Bulbs: E26,E27” regarding globe E27 LED light bulbs, in this post, we will talk about GU10 LED spotlights.

 GU10 LED Spotlights

GU10 spotlights have been commonly used in spotlighting applications. Traditional GU10 spotlights are halogen lamps. Typically, under current light efficiency of LEDs, 3W LEDs is equivalent to 20W halogen lamps, and 5W or 6W LEDs is equivalent to 40W halogen lamps in terms of lux. Here the picture shows a 4*1W GU10 LED spotlights. See Fg. GU10 LED Spotlights.

From the appearance point of view,  GU10 LED spotlights and halogen spotlights look very similar. However, in fact, the difference between them is tremendous.

GU10 LED Spotlights Dimension

Light Source: light source is the essential difference between LED spotlights and halogen 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.

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

Driver: furthermore, LED spotlights 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 GU10 LED spotlight exploded view. The spotlight is decomposed into 7 components as can be seen from the diagram. The following are the corresponding annotations.

GU10 LED Spotlights Components

1. Lens: beam angle usually customizable
2. Screws
3. LEDs
4. MC PCB
5. Heatsink
6. Plug holder
7. Replacable plug: GU5.3,E26,E27,B22

I’ve been thinking to show people some interesting stuffs about LED lights, eg. LED light source, LED lighting fixtures, LED light components etc. In a series of articles (this one would be the first post, and there will be some other followed up), I will demonstrate some typical LED light bulbs by using some diagrams and annotations. Now just let’s start by one of the most commonly seen globe LED light bulbs: E27.  See Fg.: LED Light Bulbs E27

 

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.
