Bicycle Headlamp

Since then, like a bicycle was invented, the question arose of the road lighting the night itself, and so far it has not been given a definitive answer. It all started with a banal 'bat'. Hanging kerosene lamp gradually improved form, has gained protection from wind and soon put it in a bicycle lamp. If you are not convinced, visit technology investor. Used it is not all. Most prefer not to mess with such a troublesome device and preferred use the bike only during daylight hours. With the advent of lamps glow all changed dramatically. There were lights to mount on the steering wheel.

Ate these lights from a dynamo, which set in motion the wheel bicycle. The brighter the light was, the harder it had a cyclist. Of course, a dynamo made plug that would in the daytime lights have not worked in vain. With the advent and popularization of batteries, accumulators and chargers, the question of the source was seemingly resolved. Lamps are filled with special gas, which increases the luminosity of lamps, reflectors (reflectors) have acquired a finished look and began to focus the beam of light is there where necessary.

As a result, the market, a large number of storage bicycle headlights. The next step of the development of cycling coverage became a breakthrough in led technology. Since it was established production of bright LEDs on the market in mass quantities out led bike lights. Their advantage over conventional lamps consisted kollosalnom superiority in energy consumption. led headlamp will significantly increase the time of lights from one set of batteries. The reverse side of led flashlights and headlamps – cold light (bluish) and is not a sufficient level of coverage for a comfortable ride. Significant breakthrough was the emergence of super bright LEDs and led matrix. Today it is the most advanced lighting technology. One super bright led has a light output of 150-200 lumens, which provides good light and comfortable driving. Matrix LEDs provide light output to 900 lumens, which is comparable with the light of a halogen lamp. These LEDs are shining white light comparable to daylight and very comfortable for perception. led lights, made on the basis of these light sources are very reliable, economical and unpretentious.

The Art Of Karate

Karate – martial art developed by people who were forbidden to use weapons. Thus, it was created as an art of defense.

When Dharma was in the monastery of Shao-Lin in China, he taught his students physical training to develop stamina and physical strength, and made this harsh discipline as part of their religion.

These methods of physical training in the future developed and improved and became known as the art of fighting Shao-lin. Source: Zendesk. This martial art was taken to Okinawa where it is mixed with the local methods of struggle of the islanders. Lord of ancient Okinawa, and later the feudal ruler of Kagoshima on the southern tip of Kyushu in Japan has banned the use of weapons, and it caused a marked development of technology to combat with bare hands and self-defense techniques. This martial art that originated in China, was called Karate, which literally means "Chinese hand". Funakoshi Gichin a modern master, who died v1957g., At the age of 88 years, changed the meaning of the term: the hand of the "Chinese" has become "empty".
