LED ceiling lamps: large international companies in power

 

The end of 2011, the 8th China International Semiconductor Lighting Exhibition and Forum activities, the major domestic and foreign enterprises collision and impact, we are true and felt a strong sense of the difference between domestic enterprises and large enterprises. Introduced to the President of the International Commission on Illumination (CIE), in the amount of the overall marketing of the global LED ceiling lamps industry, Nichia, Cree, OSRAM these international giants have occupied the top of the charts, and far more than the opponent. China LED companies falls far short of internationally renowned and large enterprises from the size and strength, it is true, but also domestic LED enterprises have to face problems. To sum up, the main bottlenecks in the following aspects.

 

Compared with the international giants, the overall size of the LED business is relatively small and scattered strength. Earlier data show that the average annual sales of our LED ceiling lamps business in about 30 million yuan, the largest chip enterprises with annual sales revenue of 10 billion yuan, about $ 100 million, while U.S. Career sales in 2009 reached $ 567 million. The gap is obvious. With the technological advances faster and the formation of large-scale application of the market, LED large-scale production capabilities and product performance requirements will be higher, the LED high bay lamps business bigger and stronger, accelerate structural adjustment of the pressing needs.

 

The so-called collaborative innovation, the innovation is to focus on the goal, all forces work together, complement each other, with the collaboration of innovative behavior. New mechanism, a new model of collaborative innovation, collaborative research and market applications, LED domestic enterprises in the new era of a new initiative and new ideas.

To solve the problem of led ceiling lamps temperature

To solve the problem of led ceiling lamps temperatureLED life, for example, to switch the the siliceous packaging materials and ceramic packaging materials, make the life of the LED’s to improve a number of white LED light spectrum contains wavelengths below 450nm short wave length light, led ceiling lamps, traditional epoxy encapsulated materials vulnerable to short wavelength light damage, led high bay, high-power white LED light to accelerate the degradation of packaging materials, according to the test results of the industry, led ceiling lamps, continuous lighting is less than one million hours of high-power white LED brightness has been reduced by more than half simply can not meet the basic requirements for lighting long life.

For the LED luminous efficiency, led ceiling lamps, improve chip package structure, can achieve the same level with the low-power white LED. The main reason is the current density increased by more than 2 times, not only does not easily removed from large chip light, the results may even lead to the dilemma of the luminous efficiency than the low-power white LED. If improving the electrode structure of the chip can theoretically solve these light extraction problem.

In order to reduce thermal resistance, led ceiling lamps, and many foreign LED manufacturers will set the LED chip surface of the radiator made of copper and ceramic materials (the heat the sink), and then using the welding and the heat of the printed circuit board with a wire connected to the use of forced air cooling fan radiator. Germany OSRAM Opto Semi conductors Gmb experimental results confirmed the structure of the LED chip can reduce the thermal impedance of the welding point of 9K / W, about 1/6 of the traditional LED LED package is applied to 2W power LED chips bonding temperature than welding points 18K, led ceiling lamps, even if the printed circuit board temperature rise to 50 ° C junction temperature at most, only about 70 ℃; led ceiling lamps, thermal impedance contrast in the past reduced the LED chip junction temperature will be a printed circuit board temperature. Therefore, it is necessary to reduce the temperature of the LED chip, in other words, reducing the LED chip to the thermal impedance of the welding point, can effectively reduce the burden of the cooling effect of the LED chip. On the other hand even if the white LED is able to inhibit the thermal impedance of the structure, led ceiling lamps, if the heat conduction from the package to the printed circuit board, the results still make light-emitting efficiency of LED temperature rise fell sharply. , Matsushita Electric Works, the development of printed circuit board and package integration technologies, the company will be 1mm square blue LED flip chip package on the ceramic substrate,led ceiling lamps, followed by and then paste the ceramic substrate in the copper printed circuit board surface, according to Panasonic reported contains the modules of the printed circuit board, including the overall thermal impedance is about 15K / W or so.

The colorful led ceiling lamps: Little Rainbow

The colorful led ceiling lamps: Little Rainbow

 

Today, after 80 men and women who, like personalized ornaments to decorate the room. Used to entertain friends and family living room, but also need to have a unique layout. Checkers came Matsushita Electric lighting shop, store display Twin Pa series of seven-color led ceiling lamps fit the needs of young people, let me bring everyone together to look at this new upholstery!

7-color LED lights: the dimming of the lamp can be monochrome, this lamp is adjustable 7 colors red, orange, yellow, green, blue, blue, purple, it is suitable for installation in the living room, holidays add to the atmosphere. Polystyrene Globe (white decorative box): milky white shade weaken the intensity of the light, adding to the indoor softness. In fact, led high bay can offer a similar lighting effect, but consume more energy compare with led ceiling lamps.

Promise dimming ballast: the past, the lights are to adjust the brightness level by regulating the number of lamp this section light Promise dimming ballast to regulate and scope of regulation, but also will not damage the lamp.

Remote Control: In addition to the wall switch, this light is also equipped with a remote control to facilitate the middle of the night to use the toilet. Basic remote control device can replace the switch, the clerk field test a bit, convenient and easy to use. On the remote control memory keys, remember that you like the brightness of the next turn on the lights Press to be.

The Panasonic Little Rainbow led ceiling lamps, a new original and innovative LED lights on the basis of seven kinds of color change. More environmentally friendly energy saving lights Promise dimming features than any other ballast.

No regret to use led ceiling lamps

Everyone has a comfort zone in this region are very self, do not want to be disturbed, do not want to push, do not want to and unfamiliar face conversation, do not want to be accused of not willing to do things in accordance with the prescribed time limit, does notwilling to take the initiative to care for others, unwilling to think about others, led ceiling lamps, what did not expect. This student is very easy to understand, and sometimes students even went to “cold” personality, “these words detached, counted as a compliment. On the contrary, however, after work, you must try to change this situation. Otherwise, you will soon become a cocktail party, led ceiling lamps, only no one took any notice of the object, or soon because of the pressure and endocrine disorders. However, if you can quickly break the comfort zone in which the students of faster than others to handle the business, interpersonal relationship between the public opinion, it can quickly come to the fore.
No regret to use led ceiling lamps
During the meeting, a stay in mind comfort zone of people will listen to the discourse of the leading passive, passive standby, complete superior to the very dead things, but never cared about anything other than the matter, would not think more than do the step, led ceiling lamps, following someone else’s work more easy to use. Those who dare to break the comfort zone and dare to put forward their own views and do not understand at the appropriate time, and get higher recognition and pointing to the task at hand as soon as possible to complete, and ready to accept criticism from others and adjust. (Note: Never wait for others to say what you think, which is typical of the former)

Work encountered a new colleague, he pretended not to continue their work. Little do they know new colleagues soon become their own boss. The latter is generous and polite, led high bay, introduce yourself, and understand each other and their relationship.

At the party, the former always wait for others to speak, like privately comment on each other’s speech; If this table does not speak, and that until the end of the meal, no one knows you. While the latter is a brave and with a meal began to introduce and chat, it looks very difficult, led ceiling lamps, sometimes beneath the face, but often you will find each other how much hope and you say a few words.

Only a small few examples, but I want to clarify is that college students leave the campus at the same time we must work to “arbitrary” in the campus away from the side, led ceiling lamps, as soon as possible out of their comfort zones and start doing and the preparation of this social exchange.

Japan as the world’s largest LED output value, according to statistics, in the context of energy conservation, the LED market, the annual growth rate of 70% to 80%, the market capacity in 2010 reached $ 1.1 billion, will reach $ 11 billion. METI announced on July 1, 2011 to amend the Electrical Appliance and Material Safety Act so that the part of the contents of the decree. According to the latest requirements of the decree, to enter the Japanese market led ceiling lamps and LED light fixtures will start on July 1, 2012 shall be affixed to the circular PSE mark. This marks “the led ceiling lamps” Electrical Appliance and Material Safety Law “control object”.

 

Safety and electromagnetic compatibility of the Japanese LED product certification standards are currently only province to make a province so that the two harmonized standard has not yet introduced. led ceiling lamps -related IEC standards are not Electrical Appliance and Material Safety Law “in the acceptable range. From July 1, 2012, the most feasible and most cost method is based on Japanese province to make a technical benchmark manufacturing LED bulbs and led ceiling lamps.

 

The scope of the control object is limited to the rated voltage of 100V ~ 300V, rated power greater than 1W use 50Hz and 60Hz AC circuit, led high bay lamps and bulbs. Products classified as new additional LED bulbs or led ceiling lamps “household fluorescent chandeliers, incandescent bulbs, fluorescent lamps, etc.; some lamps, rechargeable flashlight, lights, decorative lights, portable lights and garden lights using LED as light source, but are not classified as “LED lamps.
