Embodiment Construction

[0028] See Figures 1 to 4:

[0029] A method for driving LED lighting. The power supply generates an over-rated pulse current with a certain duty cycle through a pulse generator, and increases the frequency of the pulse current to increase the energy of the excited LED photons. When the pulse frequency is KHz, the energy of the photons is 10 to the -30th power (J) when the frequency is MHz, its energy is 10 to the -27th power (J) increased by a thousand times, when the frequency is GHz, its energy is 10 to the -24th power (J) and A thousand-fold increase, so the energy of a photon will increase by a factor of 1,000,000 in the frequency range that the electronic circuit can produce, when both reducing the constant power supply and increasing the energy of the photon work together. Other lighting sources are incomparable in terms of energy saving. The super-rated pulse current drives the LED to emit light at intervals and super-brightness, and the interval frequency reaches a c...

Abstract

The method comprises: after powering on, the pulse generation device generates a pulse current being over the rating and having a certain duty ratio; the over rating pulse current has frequencies from 1KHz to 1GHz; the over rating pulse current is used to drive the LED to generate a ultra brightness light in certain time interval; the frequency of the time interval reaches a required high frequency such that the human eye considers it as a continuous light. The driving circuit comprises: a frequency generator, a pulse control unit, a pulse detection unit, a reference current unit and a comparator.

Description

【Technical field】 [0001] The invention relates to LED circuit technology, in particular to a method for driving LED to emit light and a driving circuit used in the method. 【Background technique】 [0002] Light-emitting diodes (LEDs), due to their small size, bulbs without filaments, power saving, low heat generation, long life, uniform and clear light, have tended to replace traditional light sources. However, the traditional driving method of LED makes the brightness of LED insufficient, which limits the expansion of the application range of LED. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a method and a driving circuit for driving an LED to emit light, which can make the LED emit light super-intensively and efficiently. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] Provided is a method for driving LED lighting...
