The smart lighting we usually say refers to wireless control of lights through wireless connections such as Bluetooth, WIFI or Zigbee. Dialog's recently launched intelligent lighting solution iW6401 was developed based on Bluetooth 4.0. According to Hubie, director of marketing for solid-state lighting products at Dialog Semiconductor, this product has the low power consumption and high reliability of Bluetooth itself. According to the test, the minimum power consumption of the transceiver can reach 5mA, and in the case of sleep mode. Up to 5nA. In addition, as the world's first fully programmable digital LED control chip, the iW6401 not only has a leading cost advantage, but also has a flexible transformation method. This is also the most advantageous feature of the iW6401.
Powerful smarteXite technology platform
smarteXite is Dialog Semiconductor's next-generation technology platform that enables a new generation of highly flexible, programmable LED driver ICs for smart lighting applications. In addition, because smarteXite is based on fully configurable logic, it is the first LED driver technology that easily and directly supports wireless connectivity, light sensor control and can be easily integrated into lighting control systems.
smarteXite provides ultimate flexibility
As the first device in the smarteXite series, the iW6041 can support multiple dimming interfaces. According to Hubie, these dimming methods are not only through a simple mains switch for digital dimming and button-switch based dimming, but also The latest Ledontron digital dimming protocol. All of these dimming curves can be configured through memory for the best end-user lighting experience, Hubie emphasizes.
With the standard C digital interface, the iW6401 based on the smarteXite platform can be used as a powerful front-end system for wireless communication modules such as Bluetooth, WIFI or Zigbee. It also directly connects sensors for color and proximity sensing.
According to Hubie, the iW6401 also combines Dialog's strength in configurable power management solutions with cutting-edge digital signal processing. This makes it the world's first programmable AC/DC LED tube driver IC. This makes it easy for engineers to complete and configure the lamp design through software.
Unique programmable calibration
According to our understanding, many LED bulbs cannot be calibrated for brightness, color, etc. after being assembled, which will cause some LEDs to be eliminated and waste. The Dialog's iW6401's unique digital calibration technology allows OTP programming in the finished product chain at different stages of the product, calibrating the LEDs, and using diagnostic functions to achieve complete manufacturing process control, with final production stage calibration for ultimate precision. Light output.
OTP programming can be done in different stages of the finished product chain
According to Hubie, in addition to the driver chip after the correction and factory pre-configuration, Dialog can also be programmed online during the test of the driver electronics module, through the ICT change program, to achieve the purpose of calibration. In addition, after the product is assembled, the bulb brightness can also be adjusted according to customer specifications during the bulb function test after bulb assembly.
"Dialog will provide a calibrated power reference design box that allows the lamp chip to use this decoded input signal to adjust the lumen size and fine-tune it in this way, which is the only product on the market that can do this," Hubie stressed.
Excellent Ledotron dimming
We are familiar with LED dimming methods such as thyristor dimming, switch switching dimming and PWM dimming. As a well-known lighting manufacturer, Dialog has its own advantages in dimming technology, including: extensive dimming technology capabilities, the latest digital control and processing technology, wide-area dimming range, and lowest standby power consumption. Flexible programmable, digital fault protection and programmable thermal derating.
In pursuit of dimming technology, Dialog introduces a dimming method called Ledotron in its products. To replace the traditional dimming.
The basic working principle of Ledotron
Ledotron is the brand name of Osram and Instar for the new digital dimming technology, DLT (Digital Loadside Transmission). DLT is a new dimming control mode, plug-and-play dimmer, which is used to replace and extend the phase-cut dimming technology. This is a digitally addressable multi-channel protocol that supports group addressing, adjustable white light and color control. It not only solves all the problems of the phase-cut dimmer, but it can also be modified to standardize in IEC62756. Open standards, no authorization required.
Borrowing this dimming technology not only solves all the compatibility problems of the phase-cut dimmer, but also has the advantages of high power efficiency, no audio noise, no flash, etc., and it is much higher than the traditional phase-cut dimmer. Efficiency, the ability to connect any number of bulbs (limited only by total power) is also popular in the market. This dimming method allows the cable between the dimmer and the Guangyuan to be up to 100 meters long. All of the above advantages are destined to revolutionize the new round of dimming in the future.
Since it is said to be intelligent lighting, it is necessary to have intelligent control of the lighting equipment. Speaking of this, it can be said that the rapid development of smart phones has helped the rise of smart lighting, because the current practice on the market is to develop control devices on smartphones. But for some vendors, the cost of developing these software investments is too great. Dialog takes this into account and provides a complete solution that users can develop with their open APIs.
Every advancement in technology will bring new convenience to people's lives. What kind of convenience will Dialog bring to the smart lighting brought by this technology? Let us be full of expectations and wait for the coming of change.
Take a deep breath, close your eyes, the world has the freshest oxygen ... Yu Quan's "Deep Breath" is well known to us, but as the environmental problems become more and more serious, the haze sky also increases, PM2.5 PM10 and so on Vocabulary has also been mentioned more and more, and air purifiers have quickly become popular on the market with this "air quality" trend. Along with this, the air-clean brand has sprung up, and various technologies are dazzling. Which ones are indeed effective and which are just tasteless propaganda? How does the Air Purifier bother us to get rid of pollution? And look at the editors for you.
Analysis of air purifier
The critical value of PM2.5 content is 75 μg / m3
The pollutants in the air mainly include soot, total suspended particulates, inhalable particulates (PM2.5) and fine particulates (PM10). The smaller the diameter of the particulates, the deeper the part that can enter the respiratory tract. 10 micron diameter particles It is deposited in the upper respiratory tract, and particles below 2 microns can penetrate 100% into the bronchiole and alveoli.
1k-5k air purifier prices vary greatly
The air purifier products on the market not only have various functions, but also have prices ranging from thousand yuan to tens of thousands. The pricing of imported products is generally higher than that of domestic brands. Except for the core technology of many brands, the promotion of purification effects is similar, and consumers need to choose according to demand.
The air quality standard of 74 key cities is only 4.1%
According to the data of the press conference held by the State Council Information Office on June 4, according to the new "Ambient Air Quality Standards", the six pollutants SO2, NO2, PM10, PM2.5, CO and O3 were evaluated, 74 new standards In the first phase of monitoring and implementation, the proportion of cities that met the ambient air quality standards was only 4.1%, and the other 256 cities implemented the old air quality standards, and the proportion of cities that met the standards was 69.5%.
Air purifier sales increased by 90.5% compared with last year
According to a report recently released by the China Electronics and Information Industry Development Institute, due to the haze weather, air purifiers have become the most concerned home appliance products, with sales of nearly 2.4 million units nationwide last year, a year-on-year increase of 90.5%; retail The amount reached 5.6 billion yuan, a year-on-year increase of 105.9%.
Hepa Air Purifier , the HEPA filter needs to be replaced in March
The filter of the air purifier is the same as the filter of the water purifier, and it is not effective for a long time. After long-term use, the accumulation of dust on the surface of the filter will also cause the filter to gradually fail. Therefore, when the haze is more serious, the non-washable HEPA filter needs to be replaced every three months.
Merchants claim that the purification rate is more than 99% for the concept of stealing
99% or even 99.99% seems to have become a slogan for many air purifiers on the market. Many brands of products promote their high removal rate of PM2.5 and formaldehyde. In fact, this kind of publicity is more of a kind. The slogan of stealing the concept, the removal rate of 99% is the effect of the material itself on PM2.5 and formaldehyde, not the effect of actually running in space.
