And the function mode of the pulse width modulation module 61, the central control module 62 and the sensing module 63 is also big Cause as hereinbefore, it is unique unlike, when indicator sensor sensing turns left, first auxiliary light emission two positioned at left side Pole pipe 52b brightness can strengthen, to illuminate the road conditions in left side, as shown in figure 8, light area A can be the primary LED 51 The region irradiated, and the region that light area C is irradiated for first additional LEDs 52b, turn in this way, can increase Security when curved.
In summary, the invention has the characteristics that：
First, set by the collocation of fill-in light cup and additional LEDs, and by the pulse width modulation module Regulation and control, it is possible to reduce the consumption power of the primary LED, and then the operation temperature of the primary LED is reduced, and improve Service life.
2nd, can basis by the setting of the pulse width modulation module, the central control module and the sensing module Different vehicle condition and brightness and the consumption power for regulating and controlling light emitting diode, and coordinate the set location of fill-in light cup, when turning, Adjustment light area can be corresponded to, to improve the security in driving.
3rd, by the setting of the radiating module, heat energy can be accelerated to shed, with reduce the primary LED, this first The operation temperature of additional LEDs, second additional LEDs and the 3rd additional LEDs, extension is used Life-span.
4th, by the setting of the antiglare module, high beam or dipped headlight can be switched to, without setting respectively forward According to down according to light emitting diode, cost can be reduced and improved using upper convenience.
Therefore great progressive of the invention and the important document for meeting application patent of invention, hence file an application in accordance with the law, pray an ancient unit of weight office early Day grants quasi patent, and true feeling moral is just.
The present invention is described in detail above, only as described above, is only the preferred embodiment of the present invention, When the scope implemented of the present invention can not be limited.I.e. all equivalent changes and modifications made according to the present patent application scope etc., all should be still In the patent covering scope for belonging to the present invention.
