The LED phytolamp on the solar battery #1

For the plants growing in room conditions and lacking a sunlight (especially during the winter period) were thought up and for a long time phytolamps are used. The science knows for a long time that from all range of light waves which is possessed by a sunlight, light waves with the wavelength of 400-500 nanometers (blue light) and 600-700 nanometers (red light) are the most important for plants. Blue light promotes process of photosynthesis at a plant and is responsible for development of leaves and growth of a plant. Red light also promotes photosynthesis and is responsible for development of root system, maturing of fruits and blossoming of a plant.

There are phytolamps in which the gas-discharge lamps containing vapors of mercury, sodium and xenon to provide plants with light of a blue and/or red range of radiation are used. The following shortcomings are inherent in such lamps: big dimensions, big energy consumption, need of special utilization. Such lamps are generally used for cultivation of large volume of vegetable production for commercial purposes.

With development of science and emergence of new technologies, in lighting since recent time light-emitting diodes began to be used. Thus, phytolamps on light-emitting diodes in which as a source of radiation blue and red light-emitting diodes are used began to appear. Similar lamps easier, safe, have bigger service life and use less energy, but they more expensive as they for work need the converter of tension and the cooling system that light-emitting diodes didn't overheat. Therefore, such lamps are used in smaller scales and often for houseplants.

Now let's present a situation that we live in the city where the sun in enough happens only in the summer. In the fall and winter of the sun it is few. We live in the small apartment where there isn't enough place, and we have a pot with a small flower which costs on a window sill...

To buy the big phytolamp for us there is no sense. But we with pleasure would buy the compact phytolamp which won't be able to replace to a plant the sun, but at least will give it a little light during the winter period.

Thus, I had an idea to construct the compact phytolamp on the solar battery which will be to establish once near a plant enough and not to worry any more that the plant doesn't have a sunlight. But finally, this idea came after I saw in the shop garden lamp solar powered (figure 1).

In order that to remake the garden lamp in the phytolamp, it is necessary to change a few design, to add a reflector and to use 2 light-emitting diodes of red and blue color. Here that at me it turned out...

2 - solar battery; 3 - reflector; 4 and 5 - LEDs; 6, 9 and 10 - accumulators.

The alternativeness of this phytolamp is only how accumulators settle down.

My phytolamp works at the solar battery. For a battery charging of rather day or artificial light. The phytolamp has a simple design and will have low cost. The top part of the phytolamp is removed from the holder, and for charging of accumulators it can be put in lighter place.

Hello! My name is Dmitrii Semakov. I'm from Russia, Sankt-Petersburg.

Have a patent for a invention in Russian Federation (2577463).

If you are interested to use the patent for this device, I am happy to consider your offer.

Thank you!
