Analysts said that although the energy-saving lamp industry will shrink in the next few years, two factors will make Sunshine's energy-saving lamp business maintain growth: 1) Philips will integrate suppliers, Sunshine's market share will expand; 2) Development and Reform Commission In February, the “China Roadmap for Gradually Lowering Fluorescent Lamps†was released, and the small factory share with backward production processes will gradually be integrated into the leading industries such as solar lighting. Analysts believe that the solar lighting business is highly market-oriented and there is no risk of negative reporting.
Everbright Securities analysts believe that Sunshine Lighting will have a stronger industry position in the LED era than in the era of energy-saving lamps. The light-duty properties of energy-saving lamps are strong. The world's top three lighting companies Philips, Osram and GE rely on their respective strategic suppliers. Sunshine is Philips' largest supplier; LED lighting has stronger electronic industry attributes and higher technical barriers. The scale effect is also more pronounced, and the potential market space for sunlight is greatly increased. Sunshine also achieved volume shipments of LED products for the North American electrical retail chain Lowes.
In the long run, the integration of LED light sources and lamps is an inevitable development law of the industry. Companies that have layouts in both aspects will benefit significantly.
The proportion of LEDs in sunshine lighting revenue has increased from less than 8% in the first half of 2012 to 27% in the first half of this year. Analysts expect to increase to more than 50% next year. With the increase in LED ratio, the company's valuation will be Close to the electronics industry, Everbright Securities maintains a Buy rating.
The Co-Al Co-doped Barium Titanate
Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company
through repeated experiments. By Researching the influence of Co-Al Co-doping
on the structure and properties of Barium Titanate-based piezoelectric
ceramics, the formulation and preparation technology of Barium Titanate-based
piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional
solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N),
dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34.
Barium titanate lead-free piezoelectric
ceramics are important basic materials for the development of modern science
and technology, which was widely used in the manufacture of ultrasonic
transducers, underwater acoustic transducers, electroacoustic transducers,
ceramic filters, ceramic transformers, ceramic frequency discriminators, high
voltage generators, infrared detectors, surface acoustic wave devices,
electro-optic devices, ignition and detonation devices, and piezoelectric
gyroscope and so on.
Application: military, ocean, fishery, scientific research,
mine detection, daily life and other fields.
