Mao Shuo Power Dongjun Fang Jibin said that in 2013, the focus will be on expanding the low-power LED power supply market. The low-power LED power supply will achieve 10 million sales last year. This year's sales will reach more than 20 million, which means that sales of low-power LED power will increase. Doubled.
Low-power LED power supplies are generally used in conjunction with indoor LED lights. Fang Jibin further said that the company has planned to release some small-power LED power supply capacity this year, but there is no clear target yet. This year, it will focus on the production of low-power LED power supply.
In the company's total business, high-power LED power supply accounts for a large proportion, while low-power LED power supply is relatively small, Fang Jibin revealed that because the indoor LED lamp price is relatively cheap, the low-power LED power supply gross margin is relatively low compared to the high-power LED power supply. One point, the current gross margin of low-power LED power supply is estimated to be around 20.
It is expected that the indoor home LED lamp market will be very large next year, and the company will gradually expand the production of low-power LED power according to the market conditions. Fang Ji Pen added.
It is reported that the US Congress has passed the ban on incandescent lamps. The United States will stop selling the best-selling 40-watt and 60-watt incandescent lamps on the New Year's Day in 2014. It is worth noting that China will also regulate the regulation of incandescent lamps. Some industrial applications have expanded into the field of indoor lighting.
The company announced in the third quarter that its operating income was 399 million yuan, an increase of 6.73 compared with the same period of the previous year. The net profit attributable to shareholders of listed companies was 31 million yuan, a decrease of 18.86 compared with the same period of the previous year.

Casting polyurethane prepolymers involves a process where a liquid mixture of polyols and isocyanates is poured into a mold or container and allowed to cure or solidify. This process is commonly used in various industries such as automotive, construction, and manufacturing.
Here is a step-by-step guide on how to cast polyurethane prepolymers:
1. Prepare the mold: Clean the mold thoroughly and ensure it is free from any debris or contaminants. Apply a mold release agent to facilitate the easy removal of the cured polyurethane.
2. Measure and mix the components: Measure the desired amount of polyol and isocyanate components. The specific ratio will depend on the desired properties of the final product, which can be found in the product's technical data sheet. Pour the measured components into a clean mixing container.
3. Mix the components: Use a mechanical mixer or a high-speed drill with a mixing attachment to thoroughly mix the polyol and isocyanate components together. Make sure to mix for the recommended amount of time specified by the manufacturer to ensure complete homogeneity.
4. Degassing: After mixing, it is important to degas the mixture to remove any trapped air bubbles. This can be done by placing the mixture in a vacuum chamber and applying vacuum pressure for a specified period of time. Alternatively, a vacuum degassing unit can be used.
5. Pouring the mixture: Once the mixture is properly degassed, pour it into the prepared mold or container. Take care to avoid introducing any additional air bubbles during the pouring process.
6. Curing: Allow the poured mixture to cure at room temperature or, if necessary, in a temperature-controlled environment. The curing time will vary depending on the specific polyurethane prepolymer used and the desired hardness or flexibility of the final product. Follow the manufacturer's recommendations for curing time and temperature.
7. Demolding: After the polyurethane has fully cured, carefully remove it from the mold or container. Use caution to prevent any damage to the cured part.
8. Post-curing (optional): Depending on the specific polyurethane prepolymer used, post-curing may be required to optimize the material's properties. This can be done by subjecting the cured part to elevated temperatures for a specific period of time.
It is important to note that casting polyurethane prepolymers requires proper safety precautions, such as wearing appropriate personal protective equipment (PPE) and working in a well-ventilated area. Always follow the manufacturer's instructions and guidelines for handling and working with polyurethane prepolymers.
