Smart lighting products to catch up with cloud IoT applications
With the promotion of environmentally friendly LED lighting, green energy-saving and intelligent buildings, intelligent lighting has gradually moved from industrial and commercial buildings, government units and public buildings to general communities and homes, providing more energy-saving, smarter and more convenient control. In order to create a different atmosphere environment, to improve the quality of people's living; more with the popularity of the Internet of Things, through the cloud-controlled services, will become the mainstream of intelligent lighting development...
Intelligent lighting from basic lighting needs to ambient control
Most of the traditional lighting control methods are based on fixed-position switches. In recent years, with the popularity of smart phones and the trend of the Internet of Things, the new generation of lighting has become intelligent, through the combination of sensing devices and information management. The platform, with the Internet, integrates lighting with the living environment to achieve the application of "smart lighting".
Compared with traditional lighting, intelligent lighting can provide people to remotely monitor these lighting devices through mobile devices, and can change the light color according to the mood to create different atmospheres, and even further detect whether people are on the scene. And sense the physical and environmental conditions of the people on the scene, to automatically open and close or adjust the brightness, color temperature and other capabilities to create a more comfortable, more humane comfortable lighting space.
All major manufacturers launched smart lighting products to create a photo atmosphere situation
In recent years, the rise of the LED lighting industry, many IT manufacturers, existing lighting manufacturers have launched LED lighting products, the introduction of various specifications of LED bulbs, to emphasize more power-saving, more environmentally friendly features, to grab a huge change Retrofit market. However, the supply of LED chips is excessive, and the price of purely illuminating LED bulbs is soaring. Therefore, it is only possible to introduce differentiated products with different characteristics to survive in the market.
Smart lighting seems to be the antidote to this industry. Built in ZigBee or Z-Wave chips in LED bulbs, giving it the ability to control wirelessly, and then pairing with smart home hub products and exclusive apps, you can make smartphones or tablets. Through Wi-Fi and 3G/4G, you can go home and control at home or outside to control the opening and closing, brightness, color temperature, and even color of the light bulb to stimulate market demand.
Among the smart bulb products, products with full color dimming function are most topical and market attractive. Many manufacturers have introduced such products, and can control the opening and closing, brightness and color of the light bulb through a mobile phone or a tablet: there are also timing settings to control the behavior of the light bulb to enhance the application value of the LED light bulb in the home environment.
In 2012, the Dutch company Philips (Philips) launched the first generation of Hue smart LED bulbs, connected with its Hue Bridge bridge to the home Wi-Fi wireless router, in order to control the opening and closing, light color and light bulb of the bulb through the smart phone. Brightness provides high quality and versatile lighting environment. The product was put on the Apple Store at the end of October of that year, attracting a lot of attention from the IT industry and the lighting industry.
Smart bulb lighting control has been designed wirelessly
In the design of new LED bulbs, most of them choose to use wireless remote control to achieve, and the operators are aiming to use mobile phones or tablets as remote controllers, as the product design direction of smart bulbs. This is because the traditional wired control aspect, when it comes to wiring on the wall, requires a large cost, preferably when planning a new building; but most of the general reloading market does not have this new control method. Therefore, the choice of a convenient, remotely controllable wireless protocol is a common design goal for manufacturers.
In the past, there were many types of wireless communication, and most of them did not design their communication standards for "lighting". Subsequently, many emerging low-power wireless communication standards designed for smart homes have already been supplemented with "lighting" and adopted by manufacturers.
The control method is rectified and can be operated with or without the smart home Hub.
In the smart home lighting market, Philips first introduced the ZigBee wireless protocol, and with its Hue Bridge bridge intelligent lighting solution, ZigBee made a name for itself in the market. However, due to the lack of built-in ZigBee terminal devices, coupled with Philips' product portfolio, it seems that the investment cost is too high for some beginners who want to try it. (The first three Hue bulbs are paired with Hue Bridge's Starter Kit. $150), and can only be used with IOS phones, so that products can only go to high-end market routes.
Then LIFX launched the Color 1000 smart light bulb in 2012, and adopted the Wi-Fi wireless protocol. It also built the 6LoWPAN chip/connection protocol to transfer the instructions between the light bulbs, and the control can be achieved without using the bridge. Let the bulb get a lot of attention in the market.
Between 2013 and 2016, many manufacturers launched RGB Bulbs for various protocols, Z-Wave, which also requires Hub, as well as ZigBee, and Bluetooth, which is free from Hub and directly controlled by mobile phones. Therefore, the mainstream RGB, pure white dimmable light bulbs on the market use only wireless communication protocols, including Wi-Fi, ZigBee, and Bluetooth.
IT giants attack! Various camps launch different smart home support products
In view of Apple's IOS 8 officially joined the HomeKit development kit, its Works With Apple Homekit certification, so that many manufacturers can launch a variety of smart home appliances with IOS, can also be used with Siri voice command mode to control RGB bulbs, The other camp's Google also joined the battle, it bought the Nest smart home platform, and launched the Works With Nest certification, also has voice control capabilities, once again ignited the battle of the SmartHome Hub market.
Since Apple and Google have launched their own smart home platforms, the control is no longer limited to indoor homes, but can be extended to remote control when people are outdoors. In addition, voice control is supported, and the platform is supported by many vendors.
Like 2015, Philips relaunched Hue's second generation, supporting both Apple's HomeKit and Google's Nest smart home platform, allowing both IOS and Android phones to control their RGB bulbs, using their Hue App with their Hue Bridge 2.0 products. By Siri, you can voice up to 50 bulbs to achieve control changes in your home situation.
Other camps like Wink, Insteon, Belkin (WeMo), Samsung (SmartThings), Lowe (Iris) and other manufacturers have launched their own smart home Hub products, with their exclusive apps to meet the needs of various smart home appliances. . Also received a lot of support from the major bulb manufacturers. For example, OSRAM's Classic series bulbs support SmartThings or WeMo, GE bulbs support Wink, and Cree bulbs support Wink, SmartThings, Wemo, etc., and have a tying package with Wink.
Free Hub products come out to achieve regional or even remote control
The smart home products mentioned above are almost always controlled by the so-called SmartHome Hub, Bridge and other products. There are also manufacturers who choose to avoid Hub and reduce the cost of purchasing users. For example, LIFX using Wi-Fi protocol, and smart home products like Xiaomi (Mie), including Yeelight bulbs, LED desk lamps, etc., are also based on the Wi-Fi protocol, as long as they are connected to the home through their App. Wi-Fi Router/AP can be used for wireless control. Once the device is registered with the cloud, it can be connected to the cloud through 3G/4G to control the smart home appliances in the home. No need to use the intermediate Hub products. .
Manufacturers who choose to design with the Bluetooth protocol, such as MiPow (Playbulb), ADATA (Aura RGB), etc., can let users directly use the phone with their own App to achieve control functions.
Combine cloud services Intelligent IoT products to expand the intelligent lighting application front
In addition to Hub products, smart home products that combine the concept of IoT are also brewing on the market. For example, in 2014, Amazon launched Echo, a smart home application that combines AWS cloud services. Users only need one Echo to call, order, check weather, check time, check date, and use AVS (Alexa Voice Service) voice service. Set the alarm clock and listen to music. Echo's built-in speaker will reply or play back the results of the order or inquiry. Many smart light bulbs are certified by Works With Amazon Alexa, and smart light bulbs such as Philips, Cree, LIFX, and TP-Link support the Amazon Alexa standard.
Amazon AVS and IFTTT Recipe services give smarter applications to lighting products.
In addition, like the IFTTT (IF This Then That) cloud service, the Recipe function sets the bound individuals (such as products, situations, objects) under different conditions, which will trigger the behavior of other devices. For example, you can set the brightness of the bulb to increase when the weather becomes cloudy. Or change the color of the lights according to different festivals to make life more interesting.
Summarizing the future development of intelligent lighting products, it will inevitably take the cloud IoT application to achieve convenient, fast, voice-enabled, programmable applications, so that users do not even need to manually control through the mobile phone to achieve true intelligence. Lighting applications.
