And God said, let there be light, light, world.
When when we enjoy the convenience of light, living in impoverished areas of developing countries people rely on extremely dangerous kerosene lamps for lighting. GravityLight non-profit organizations generally have no access to electricity in developing countries, introducing a rely on gravity to a bag of sand power and lighting design: gravity lamp.
In fact, as early as 2013, first generation GravityLight GL01 is on Indiegogo successfully completed all preparatory, received support from more than 6,000 people, raised $ 399,590 in a month, can be said to be very popular. This time, the development team at GL01 products on the basis of the first generation, get user feedback, and after a lot of testing and improvements developed a second generation product GL02.
Why hold up a bag of sand can generate electricity?
LED lights rely on energy transformation of gravity gets electricity.
Chemical energy into the gravitational potential energy of the object inside the human body: operator takes a few seconds by pulling the beads 12 kg sandbag to a certain height.
Object's gravitational potential energy into kinetic energy of the object: once the operator let go, sandbags under the action of gravity to slow decline of 1mm per second. Dolce Gabbana iPhone Cases
Object's kinetic energy into electrical energy: sandbags in the process of falling, gear driven generator, gravity lamp will start to glow. When sandbags down to zero gravity lights stopped working.
GL02 what improvements?
GravityLight official website of the non-profit organization, GL02 into the pulley system, make it easier for users to be able to lift heavy weights.
After the improvement, the weight has not yet reached the bottom pull the bead lifting GL02 remained open, continuing to provide light in the dark. GL01 is not shiny in the process.
Although only a brightness GL02 but brighter than the GL01 top 15 lumens. And GL01 uses a new protection mechanism can ensure the physical security of overweight landing ground.
1.8 metres for more than 20 minutes of light
LED lamp lighting time depends on installation of gravity height, under normal conditions, placed in the height of 1.8 meters, can last more than 20 minutes of lighting, of course you installed height higher, maintaining longer.
Pollution-free, using the "zero" cost
Understanding how gravity GL02 LED lamp works, we know that throughout the process, gravity lamp will not release any material, so it is very clean.
After you pay for the gravity lamp, its cost is essentially zero, but may need to spend some money on eating it, after all, every 30 minutes to lift heavy weights, physical consumption may be slightly larger than normal. GL02 fuselage DC outlet, also can be powered devices such as radios.
All chips
GravityLight 22-g LED lamp on Indiegogo raising had ended on July 17, 2015, received support from 3,573 persons, raised a total of $ 267,690, far more than it raised the target to $ 199,000. GL02 cheapest one sells for $ 70, the purchaser will receive a second generation gravity LED light and 2 can connect to GL02 Satlight lights. If all goes well, is expected to be shipped September 2016.
For more cool intelligent hardware information, please pay attention to odd public number (woaiqiku), in odd public key, you can buy, and I'm not gonna tell you, register as a member of Lei feng still get super discount.
