The importance of smartphone control.
The importance of smartphones and other mobile devices will undoubtedly grow over time.These technologies have become the center of our daily life, enabling us to work on the road and manage our social life through social media.Lighting has become another part of our lives and can be controlled by mobile devices.
How does a smartphone connect to light?
There are three different "layers" (C1, C2, and C3) that define how smart phones connect to lighting.The explanation for each "layer" is mainly based on low-power bluetooth (BLE) technology, because it has great potential and is highly accepted across the industry.
First of all, traditional lighting (C0) is usually controlled by Triac or 0-10v dimmer, providing control signal to the LED module driver in each lamp.
In the first layer (C1), a dedicated controller can be added to an existing in the drive, equipped with low power consumption at the top of C0 bluetooth (BLE) sensor or switch, make smart phones directly control lighting, without the cloud server.In this C1 mode, multiple smartphone controls allow users to share lighting control with each other.
The second layer (C2) adds the cloud to the mix, which means that the user logs the data on the lighting, for example, which lights are on at which time, how many lights are on, and how much power is used.The generated data can be easily implemented on a preset basis.
For the third and final layer (C3), the wi-fi/BLE bridge is added to enable people to control their lighting through the cloud within the BLE grid.This type of setup enables people to remotely confirm the lighting status or configuration Settings at any time and at any place, or to set the most appropriate configuration in a smart space.
How does the Internet make smart phones the center of smart lighting?
The three layers mentioned above are becoming more common in lighting control for several reasons.The first reason is that the evolution of the protocol, bluetooth, can now be adapted to smart technology through low-power bluetooth (BLE).BLE is completely different from ZigBee. ZigBee does not support the direct control of smart phones, but it is the center of many IoT activities today, especially in terminal nodes.However, BLE can support grid technology and can directly control the application of Internet of things, which is very important for applications of high-density terminal nodes such as smart home.
Standards such as DALI, ZigBee and bluetooth are already in the works, as they play a key role in the core connection methods of lighting networks, sensor networks and wireless telephone networks.As a result, most of the upcoming solutions will be based on standardized hardware and firmware so that all participants in the digital lighting industry can participate in the development of a viable end-to-end solution.By the second half of 2017, most of the new smart lighting products will be based on DALI 2.0, ZigBee 3.0 and bluetooth 5.0.
The second reason is the growth and popularity of mobile networks, from 2G to 3G and 4G and LTE.These improvements ensure that smartphones can be easily connected to the cloud, allowing users to control lighting in real time from any location.In terms of the security of the information service and flexibility, smartphone control department is more suitable for developing personalized on-demand service, such as health care, or biological recognition technology for identity and pass as the password, and payment process will be much easier and safer.
Open platforms are key to success.
Because of high cost and high prices, LED manufacturers have no way to build a full proprietary connected lighting solution.In other words, the benefits of connected lighting do not outweigh the costs at this time.Therefore, in order to reduce costs, the LED industry must have a simple and open platform standard, and manufacturers can build their own intelligent lighting solutions.With the increase in cost savings and seamless integration opportunities, lighting manufacturers can freely design LED lighting systems based on open standard platforms and enhance their own newly installed systems.In addition, human-oriented lighting should be built on the same platform, with more complex spectrum control and additional network equipment in PAN and BAN.
On the open platform, manufacturers should consider trying some examples of seamless smart lighting to reduce the resistance of decision makers and accelerate the wide adoption of smart lighting, as shown in figure 2.In the United States, LED lighting manufacturers can install adjustable light drives to improve LED lighting, or continue to use traditional dimmers like Triac or 0-10v.Using an existing LED lighting system, you can replace the Triac / 0-10v dimmer with a BLE enabled dimmer or BLE enabled smart dimmer.In this way, smart phones can use remote control technology more flexibly in residential space.Using a reverse compatible smart driver, the existing controller can match the new color temperature tunable drive.In addition, LED modules, drives, and controllers can be combined into a single board (or "s-engine" intelligent engine) to reduce costs to acceptable levels.
The split-step method for seamless connection is based on the BLE solution or using the BLE-ZigBee "combination" solution.By using the BLE ZigBee solution, simple, cost-effective methods can be easily adopted.
Overall, lighting manufacturers have an obvious advantage in choosing digital lighting.To illustrate this intuitively, see figure 4.Adding bluetooth to an existing Triac / 0-10v architecture costs more, but it's cheaper than adding smart functionality to an existing dimmer.There is also a way to save more energy: add BLE to the switch and sensor, and analyze the conditions for using intelligent control while keeping the specification consistent.
In addition, by enabling multiple phone controls for any household appliance, initial investment can become more cost-effective and particularly useful when the control device is in remote control mode.
In addition to the step-by-step options described above, the new multifaceted solution will support the latest control standards DALI 2.0, BLE 5.0 (grid), and ZigBee 3.0.In addition, 2ch 0-10v dimming will be available for white tunable applications, including electric energy metering to improve energy management.
In this article, we carefully evaluated the driving forces behind intelligent lighting and human-oriented lighting solutions, and how to accelerate their adoption rate.Combining bluetooth intelligent methods (or low-power bluetooth) with optimized grids and seamless end-to-end control options may be the most effective way to transfer the Internet to people-oriented lighting.For this reason, a seamless solution based on the standard DALI, ZigBee and BLE protocols now seems to be the best and most promising approach.
Encouraging lighting manufacturers to adopt this approach is key to the prosperity of the era of intelligent lighting.This year, early digitalization of LED lighting will be based on a seamless option.The next generation of end-to-end solutions is expected to be implemented in the future, accelerating the transition from intelligent lighting to people-oriented lighting.
