Li Bingjie pointed out that the government must cultivate key industries and must provide subsidies to encourage development. If it does not do so, it will only rely on outsourcing. Every dollar of subsidy for a solar plant can generate 15 degrees of electricity, and LED is for every dollar of subsidy, which can save 83 kWh of electricity, and it needs to pay attention to LED energy-saving efficiency.
Li Bingjie emphasized that if the government can subsidize the price difference between LED bulbs and traditional light bulbs, the estimated subsidies for the past four years will be nearly 1.4 billion yuan, which will achieve energy savings of 2.5 billion yuan annually.
Ye Zhaofu said that because the South Korean government has invested a lot of resources in supporting the LED industry, it has grown from 14% of the world's output value in 2009 to 23% this year and gradually caught up with Taiwan. Ye Xifu pointed out that if one incandescent lamp is replaced with an LED lamp, it is equivalent to helping the earth to multiply 10 trees.
Recently, Taiwan’s Optoelectronics Semiconductor Industry Association promoted the “One Thousand-One Thousand-Point†demonstration program. Taiwan expects the popularity of LED lighting to exceed 30% in 2015. It is expected to complete 1,000 demonstration areas, 10,000 building demonstration sites, and more than 10 million in 4 years. LED indoor light bulbs and tubes.
Dual-band WiFi module refers to the WiFi module that supports both 2.4GHZ and 5GHz bands. The dual-band WiFi module can operate in the 5Ghz band, which is much cleaner and can easily avoid interfering with each other. The advantage of 2.4G is that it has good ability to penetrate the wall, and the disadvantage is that it is easy to be disturbed. The advantages of 5G are strong anti-interference ability, wide band width, high throughput rate, and strong scalability, but the disadvantage is that 5G is only suitable for indoor small-range coverage and outdoor bridge, and the attenuation effect of various obstacles on it is much larger than 2.4g.
Dual-band WiFi module has a stronger and more stable Wifi wireless signal, higher transmission speed, and can make wireless devices more power-saving, to meet the future high-definition and big data wireless transmission needs.
When selecting a dual-frequency WiFi module, we should pay attention to these parameters of the WiFi module: size, package, frequency range, data rate, transmission rate, transmission distance, communication interface, power supply voltage, antenna interface, etc.
Dual frequency WiFi module can well meet the functional needs of users, increase the competitiveness of the product, while the WiFi module is easy to use, can shorten the user product development cycle, speed up the product market! Users can make choices according to actual needs!
Choosing a dual-band WiFi module may need to pay attention to the following points:
(1) Consider the transmission power of the dual-frequency WiFi module
The transmitting power of the WIFI module is generally about 18dBm, and the transmitting power of the high-power WIFI module is about 28dBm.
(2) Transmission rate
Consider whether the dual-band WiFi module supports MIMO technology (that is, allows multiple antennas to send and receive multiple spatial streams simultaneously)
(3) Consider the application interface that dual-band WiFi modules can provide, which is also very important.
(4) According to the requirements of the application scenario to choose the dual-band WiFi module, not the higher the configuration, the better, the application is good, excess waste!
