In the headlight of the car, necessaries when running at nighttime are natural.
Therefore, brightness more than constancy is demanded.
There is such a reason, too and the adoption for the headlight was not advanced though LED has come to be used for the light of the car by it thinking about the energy-saving effect. easily
The LED headlight was adopted for Lexus of Toyota for the first time.
It seems to have become big news in the car industry.
When LED compares the halogen lamp etc. , quantities of light shortage cannot be denied.
The problem seems to be a design of a quantities of light improvement of the LED unit and an optical mechanism that makes it effective.
It is called a day sub-chemical industry to receive and to have developed the request of Toyota.
It is a well-known company in blue LED.
LED adopted in Lexus is said that there are 400 times brightness compared with general LED.
However, it as many as 18 is still arranged by insufficient.
It is the one to show that how quantities of light of LED are few is said.
Be for high luminance LED to be developed by the technology of the day sub-chemical industry, and the following to say that it will efficiently collect the light forward.
Koito Manufacturing that was the light manufacturer developed this mechanism.
Light came to be able to shine on before ..lightening.. with a complex mechanism.
Such an effect cannot be expected with a mirror and a convex lens of a simple parabola type alone.
When such a story is heard, the technology of Japan feels admiration when it is terrible because it renews.
It is a technology to boast to the world.
Global warming prevention [noni] must be useful for this technology.
Being possible to contribute to conservation of energy as a Japanese is glad.
