Background technology
LED is the semiconductor device for converting electrical signals to optical signal.Its structure is mainly by PN junction chip, electrode and light
System is constituted.Under positive voltage effect, electronics and hole are injected separately into P areas and N areas.When electronics and hole are entered to tying layer
When, minority free electron is compound with majority carrier and excess energy is converted into into luminous energy in the form of radiated photons.Here it is
The principle of luminosity of LED.And the wavelength of light is determined by the material for forming PN junction, the luminosity of LED is relevant with positive operating current.
LED is by energy resource consumption is low, luminous efficiency is high, environmentally friendly, long service life, numerous advantages such as safe and reliable are in illumination
Field obtains one seat, and has the continuous trend for expanding, and same LED Lighting Industries also bring very significant economic effect
Benefit and social benefit.Therefore, the rapid popularization of LED illuminations has also driven flourishing for LED driving chip industries so that
LED driving chips have become the important component part in electric power management circuit market.Because the brightness of LED illuminations is turned on it
The intensity of electric current is closely related, and constant-current driving is optimal selection, therefore, how design one kind controls to make its constant-current driving
LED lights, it is to avoid because the low driving module of the hardware service life that causes driving chip design is unreasonable be it is current and
The trend for developing later.
