The Mechanical Buzzer uses a magnet to move a reed up and down quickly to emit a lower-pitch buzz! It's quieter than the Piezoelectric Buzzer but uses more power, so you the terminals will have to be closer to the
battery packs. To use them, you'll need to match the wire colors to the
wires from the battery pack. Mechanical Buzzer Piezo Beeper,Mechanical Buzzer,Piezo Mechanical Buzzer,Low Frequency Mechanical Buzzer Jiangsu Huawha Electronices Co.,Ltd , https://www.hnbuzzer.com
On the evening of June 18, Aoyang Shunchang (SZ.002245) announced that the company's controlling subsidiary Huai'an Aoyang Shunchang Photoelectric Technology Co., Ltd. (hereinafter referred to as “Huai'an Optoelectronicsâ€) has been in contact with the Qinghe District Government of Huai'an City, Jiangsu Province. Huai'an Qinghe New District Management Committee signed the "Project Investment Framework Agreement" and plans to invest in the construction of LED epitaxial wafer and chip industrialization project (Phase II) with a total investment of 1 billion yuan.
It is understood that the construction period of the LED epitaxial wafer and chip industrialization project (Phase II) of Aoyang Shunchang will be two years. After the project is put into production, the annual production capacity of blue and green chips for lighting will be increased by about 2.4 million pieces (equivalent to 2 å‹ epitaxial wafers). ).
"At this stage, the company's MOCVD machine equipment has been in full operation, and the production capacity is tight." Aoyang Shunchang Dong Mi Lin Wenhua said in an interview with the reporter of "High-tech LED" that the upstream chip that was generally worried about the market The situation of overcapacity has been greatly improved. In the first half of this year, the overall capacity increase of the chip was not large, and it has not reached the level of overcapacity.
Lin Wenhua revealed that the Australian Ocean Shunchang Phase I LED project, which is under construction with an annual output of 1.8 million pieces of blue-green chips, has completed 50% of capacity production. At present, the project has already received 20 MOCVDs, 15 of which have been mass-produced. At the end of June, 18 units will be produced, and by the fourth quarter of 2014, 30 MOCVD equipment construction plans will be completed.
In addition to the current strong market in the chip market, the expansion of the Australian Ocean Shunchang has also received the full support of the midstream packaging companies.
In May, Huai'an Optoelectronics has signed a "Strategic Cooperation Agreement" with the domestic packaging leader Mu Linsen. Mulinsen will continue to purchase LED chips from Huai'an Optoelectronics. The total amount in two years is not less than 400 million yuan.
Similar chip manufacturers and packaging factories signed a chip supply agreement order is not new, Sanan Optoelectronics and Jufei Optoelectronics, Changfang Semiconductor and Xin Najing have signed similar agreements. In this regard, Lin Wenhua believes that this phenomenon of "carrying the group" is normal and will be the future development trend. He believes that the expansion of the packaging plant is now faster, the expansion of the chip factory is slower, and the group is more conducive to the development of upstream and midstream enterprises.
Gaogong LED reporter learned that by investing in LED epitaxial chip projects, Aoyang Shunchang has successively received subsidies of more than 40 million yuan from Huai'an local government and some streetlight projects of Huai'an government in the past two years. Lin Wenhua also said that the government will support the second phase of the project. "But the specific preferential policies and measures will be discussed later."
For the market of the chip market in the second half of the year, Lin Wenhua believes that the chip market in the third and fourth quarters of this year may not be much different from the first half of the year.
"The price of the chip that has been said has not fallen, the price is not loose, there may be room for growth." Lin Wenhua predicts that the demand side is more than the supply side. There will be no obvious changes in this year. In the second half of next year, the new equipment will be mass-produced and the situation will change.
According to the data of the High-tech LED Industry Research Institute (GLII), in the next three years, LED indoor and outdoor functional lighting continues to explode, which is the main engine for the development of the LED industry. With the continuous advancement of technology and the further reduction of cost, the penetration rate of LED lighting market will increase rapidly in the future. The potential of LED epitaxial wafer and chip market is huge, and the market structure still has many variables.
[High-tech LED reporter / Yue Mengdi] The supply and demand tension of LED chips in the first half of this year is still continuing. The situation that the demand for news chips from the major chip companies and packaging companies is in short supply is difficult to change in the short term. This has also prompted major chip factories to accelerate the pace of expansion.
