With the development of LED lighting technology, the price difference between LED lighting products and traditional lighting products has gradually narrowed, and LED lighting applications have become more and more widespread. Coupled with the implementation of the national ban policy, the global LED industry has entered a period of rapid development, and the call for LED lighting in the first year is getting higher and higher. At the same time, the concept of intelligent lighting has been hot in the LED industry for many years, and its advantages no longer need to be repeated, and intelligent lighting is also considered by the industry as a new way out after the era of LED lighting replacement. To this end, many LED lighting companies, regardless of the size of the production, regardless of whether the channel has been completed, all claim to be in the direction of intelligence. However, optimistic about the smart lighting cake is not only the LED industry, home appliance giant Haier, Internet company millet, traditional electrician leading enterprise Hongyan Electric, among which, Xiaomi's action can be described as direct and speed, many entrepreneurial companies such as LIFX, Yeelink, Magical Intelligence has been aggressively attacking intelligent lighting. Intelligent lighting into LED potential market LED lamp longevity may be a double-edged sword. Due to the long service life, the replacement market caused by natural damage is inevitably not as large as traditional lighting. After the traditional lighting market is replaced, where will the LEDs be used? This is a problem facing the entire LED industry. The rise of smart lighting in recent years may bring new business opportunities to the LED industry. It is understood that Philips Hue and the more economical HUELux are the star products of the current smart lighting market. This product is not only dimmable, color-coded, but also customizable via iOS or Android software. At the same time, Philips' newly launched intelligent lighting software platform enables users to complete intelligent product control in different scenarios, and connect LED lighting devices in the system at any time outdoors and indoors. In recent years, Xiaomi, whose layout has been expanding, is also unwilling to be lonely. In mid-October this year, four smart home products were released, including a lighting product called Yeelight Smart Light. According to related reports, Yeelight is a smart lighting startup company and completed the A round of financing at the beginning of this year. Xiaomi is its main strategic investor. According to Ye Zhaoguang founder Jiang Zhaoning, the light bulb cooperated with Xiaomi is customized, quite a little Xiaomi for the purpose, only supports the operation of controlling the light bulb through the networking of Xiaomi router. Zhao Jianping, deputy dean of the Institute of Building Environment and Energy Conservation of the China Academy of Building Research, once said that with the development of the Internet, the development of LED lighting, the future direction of lighting is on-demand lighting, according to the needs of light to design, this is the future of the Internet and LED After a better combination, one direction of development. Moreover, the output value of China's LED lighting will reach 500 billion yuan in 2015, so the market space for smart lighting will be very large in the future. Wang Xiaodong, deputy director of the Smart City Research Institute of China Putian Intelligent Lighting Research Institute Co., Ltd. (Hongyan Electric) believes that the de-switching of lighting equipment is a clear trend, which means that in the future, the switch will gradually be replaced, and the wiring will be reduced. Cost, complicated engineering, and breaking the limits of space. The biggest advantage of LEDs is that each lamp bead can be controlled separately, and the phone can be used to control the brightness and color changes. This may be the biggest market for lighting applications in the future. Wang Jun, director of Sanxiong Aurora Marketing, said. According to CSAResearch, in 2020, the global intelligent lighting market will reach US$56.05 billion. China's LED intelligent lighting market will grow at a rate of more than 30 in the next two years. LED intelligent lighting penetration will also accelerate. In 2015, it is expected to reach 8. The greater value of light application LED lighting is also gradually getting rid of the doubts of blue light hazards, opening up the scale of the market for lighting. LED lighting is shifting from a question of safety to a healthy, comfortable concern. The flexible controllability of LED lighting products makes intelligent lighting an integral part of smart homes and smart cities. Experts in the industry pointed out that at present, dimming and color temperature can be basically achieved, but the focus of intelligent control of LED lighting should not be just energy saving. Compared to energy saving, home lighting needs to emphasize healthy lighting, which means that lighting makes people feel comfortable, safe or have a feeling of leisure, and there is no pressure. The intelligent control of home lighting also needs to incorporate the concept of healthy lighting, and talk about energy saving in the case of health priority. If you want to do intelligent control, you need to do a good job in the general direction. You can make communication protocol regulations from the national perspective and height. For example, wireless control used for intelligent control, WiFi, and its signal format. This signal format is acceptable to everyone.
We're leading China R134a Refrigerant , R134a Gas, Refrigerant R134a, 13.6kg R134a Supplier & Manufacturer. We produce most kinds of refrigerant and already export to most of countries. Our quality already win a good reputation in oversea market. We can customize the R134a Refrigerant totally according to your requirements.
R134a Refrigerant also known as norflurane (INN), is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential. It has the formula CH2FCF3 and a boiling point of −26.3 °C (−15.34 °F) at atmospheric pressure. R134a Refrigerant cylinders are colored light blue. Attempts at phasing out its use as a refrigerant with substances that have lower global warming potentials, such as HFO-1234yf are underway.
Contact of R134a Gas with flames or hot surfaces in excess of 250 °C (482 °F) may cause vapor decomposition and the emission of toxic gases including hydrogen fluoride and carbonyl halides. Refrigerant R134a itself has an LD50 of 1,500 g/m3 in rats, making it relatively non-toxic, apart from the dangers inherent to inhalant abuse. Its gaseous form is denser than air and will displace air in the lungs. This can result in asphyxiation if excessively inhaled. This is what contributes to most deaths by inhalant abuse.
Aerosol cans containing Refrigerant R134a, when inverted, become effective freeze sprays. Under pressure, Refrigerant R134a is compressed into a liquid, which upon vaporization absorbs a significant amount of thermal energy. As a result, it will greatly lower the temperature of any object it contacts as it evaporates. This can result in frostbite when it contacts skin, as well as blindness upon eye contact.
