Abstract

The invention provides an LED (light emitting diode) lamp. The LED lamp comprises at least one LED light string and a plurality of control units. The at least one LED light string comprise a plurality of LED lights which are arranged between driving voltage and reference voltage and separated into a plurality of LED light groups. Each of the control unit is electrically connected with one corresponding LED light group. When the LED light string is driven, the LED lights in the LED light string are lighted on at the same time. According to variation of the driving voltage, and via the controlling of a plurality of control units, the LED lights in the LED light string are separated into a plurality of LED light sub-strings, and the LED light sub-strings are parallelly connected. The size of load can be adjusted according to the driving voltage, so that power factor is improved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a light-emitting diode lamp. Background technique [0002] Light emitting diodes (light emitting diodes, LEDs) are widely used in the field of lamps due to their energy saving, safety, and long service life. [0003] However, the load of the current LED lamp cannot be changed with the change of the driving voltage provided by the input power supply, so the power factor is low. [0004] Therefore, it is necessary to provide an improved technical solution to overcome the above technical problems in the prior art. Contents of the invention [0005] The object of the present invention is to provide a light emitting diode (LED) lamp which can change its own light emitting diode (LED) load characteristics with the change of external input voltage, thereby improving the efficiency and power factor of the diode lamp. [0006] The present invention provides a light emitting diode (light...
