Smart lights that simulate daylight variations

Electric lamps have a profound impact on the development of human civilization, but its impact on the human body is another matter. A growing body of scientific evidence suggests that artificial light can disrupt the biological clock responsible for the body's rhythm. Fortunately, lightbulb manufacturers are now trying to solve this problem - of course, here refers not only to the giants Philips and General Electric.


LED lamp manufacturer Saffron is the latest to join the camp of the company. According to reports, Saffron local time began June 23 on crowdfunding site Kickstarter for the Silk Light project financing. Silk Light is an application-controlled white LED light that adjusts its color temperature to avoid disrupting the body's natural sleep / wake cycle. According to Saffron, Silk Light emits an exciting light during the day and a warm, warm night at night, close to the 24-hour period of natural light.

Urban lifestyles allow people to enjoy only limited natural light, which can disrupt one's circadian rhythms because the body's internal clock is precisely adjusted to a 24-hour day / night cycle. Even worse, many of the devices with screens around us emit blue light that inhibits melatonin production, inhibiting people from falling asleep. Some researchers and Saffron and other manufacturers believe that the answer to this problem is to let the light bulb simulate daylight color temperature and brightness changes.

Can I accomplish this task with my existing smart bulb that supports color temperature adjustment? Maybe, but very difficult. SilkLight and its companion applications were developed specifically to address this issue. The user can follow the default plan or set the brightness and color temperature of different bulbs (or bulb sets) at different times of the week in advance. Users can even set SilkLight for specific activities.

In an email to Tech Hive, Saffron said "what makes us different from other light bulbs is primarily our nClick technology. With our unique nClick system, the user can change the light bulb by pressing the light switch 1 or 2 down Settings ", SilkLight does not require users to add wiring or install other components.

According to Saffron, users can take advantage of the Silk app to specify the specific action of the switch's push mode (supporting any standard wall switch). For example, the user may specify that the two switches be activated to activate rest and relaxation modes; similarly, pressing the three-down switch activates the exercise mode, beginning with an exciting, bright light from the fixture, as the exercise approaches the end, Relaxing light.

SilkLight uses the ZigBee wireless networking protocol to communicate with smartphones via a ZigBee-WiFi bridge. Silk Light is equivalent to a 60-watt incandescent lamp that consumes 12 watts and delivers a luminous flux of 800 lumens. SilkLight's color temperature range is 2700K-6000K. A package that includes 3 SilkLight bulbs and 1 bridge is booked for $ 99 on the Kickstarter. Saffron plans to raise $ 100,000 (about 610,000 yuan).
