Moldable silicones perform particularly well in areas where a lot of heat is generated. As a high-performance material, it can easily withstand temperatures of 150°C or higher without significantly reducing its optical and mechanical properties. With the LED light source emitting a higher density of white light from a smaller package size, and the customer's desire for smaller and lighter lamps and light sources, the temperature of the device will inevitably increase significantly. Become more attractive.
With the ever-increasing lumen density, high-brightness LEDs are currently packaged at temperatures up to 150°C. This not only poses a challenge to the epoxy sealing materials that are conventionally used for LED sealed packages, but also exposes more traditional secondary optical device materials such as polycarbonate and acrylic (acryl) to higher temperatures. In general, the optical quality of these plastic materials decreases gradually when they are above 125°C and 95°C, respectively. Epoxy resin is also at temperatures above 150°C.
Light source technologies such as candles, kerosene lamps, and incandescent lamps replaced their previous technologies and improved people’s quality of life. The use of LEDs as a light source is just around the corner and it is expected that it will enrich our lives better than all other light source technologies. LEDs have the advantages of high energy efficiency, small size, portability, durability and long life.
Multi-color LEDs controlled by a small MCU can adjust the light output to provide comfortable lighting suitable for the lighting space. The MCU can intelligently control the driver circuit (maximizing energy efficiency), monitor some conditions, and maximize energy efficiency and average life. The MCU color control LED lighting system allows people to see the world with different eye “lights”.
On December 31, 2014, JD.com and the United States reached a strategic cooperation and cooperated in areas such as smart home and channel expansion. In the 2015 development strategy, smart home appliances have become an important part of JD.com's home appliance strategic layout. Jingdong puts emphasis on the value of big data and value-added services for smart homes. Currently, Jingdong has four smart hardware sales portals, including JD+, Jingdong Super APP, Jingdong Crowdfunding, and Smart Living Hall, from finance, technology, Starting with sales and other areas, through the coverage of a large number of users, improve hardware vendor product sales.
However, Baidu is seeking another middle line, playing its current advantages as a cloud and software company, providing cloud solutions, working with hardware factories, and promoting smart devices. At present, there are music boxes, TV boxes, wireless shared network cards, routers, and cameras. , TV sticks six products. This kind of output-only software and cloud, the hardware is done by the partners' ‘to play one’s way, can complement Baidu’s most wanted user system. Second, the hardware vendors used Baidu's huge traffic system to expose the products. At the same time, the products of the same generation also enhanced user trust and accelerated market acceptance. Baidu's Internet genes continued to brand endorsements for smart hardware. However, there are risks in this model test;
1. Baidu lacks control over product design and manufacturing. The synthesis of software and hardware is not a confirmation factor. In particular, there are a variety of products from different manufacturers. The product adaptability is unstable, and the resources and manpower need to be dumped. The emperor has no way to do the same treatment for the Sangong 6 hospital.
2, this cloud output and hardware cooperation is also particularly easy to be copied, the market does not have permanent friends, once the collapse, must start from scratch, even if the same as millet to create a big ticket such as purple rice 'm' generation company also There is no guarantee that you will not be at a standstill.
In short, the Jingdong Baidu smart home platform is still on the road, it is still not clear.
Home appliance overlord self-revolution, Haier Lenovo its long way
Unlike Internet companies, home appliance companies may have more robust control over smart hardware and their layout, but there are still many uncertainties.
