Abstract

The invention discloses an LED driving module and an illuminating lamp, and aims to at least solve the problems that an existing linear constant-current driving circuit is high in cost and occupies alarge amount of space of the illuminating lamp. The LED driving module comprises a first substrate, an electronic component and a constant-current module; the electronic component is electrically connected with the input end of an LED load and drives the LED load, and the electronic component is arranged on the first substrate; the constant-current module is electrically connected with the outputend of the LED load and provides constant current for the LED load, the constant-current module at least comprises a second substrate and a constant-current IC chip, the constant-current IC chip is attached to the surface of the second substrate, and the second substrate is electrically connected with the first substrate.

Description

technical field [0001] The present application relates to the technical field of circuits, in particular to an LED driving module and a lighting fixture. Background technique [0002] In order to solve the stroboscopic phenomenon caused by input voltage fluctuations, more and more lighting fixtures use linear constant current drive circuits, by combining linear constant current ICs (Integrated Circuit, integrated circuits) connected in series to provide a constant current to the LEDs. [0003] Since the actual design of linear constant current drive needs to consider the input voltage range and strobe of the power grid, it is usually required that within the designed input voltage range, the minimum input voltage does not strobe, but at the maximum input voltage, the loss of the linear constant current drive circuit is relatively low. High, which requires high heat dissipation for the linear constant current drive circuit. [0004] In this regard, the circuit board of the ...
