Abstract

The invention discloses an LED driving power supply circuit, which comprises a power supply module, a control module, a driving module and a light emitting module sequentially connected to an external alternating current, the power supply module provides a DC working voltage for the control module, the driving module and the light emitting module; the driving module It includes one drive circuit or multiple drive circuits respectively connected to the control module. An LED driving power supply circuit of the present invention can be applied to LED lamp beads of various light sources through the same power module, which solves the problem of a single light source for agricultural lighting lamps, and realizes LED constant current control IC chips on the driving circuit. Converting the constant voltage source into a constant current source suitable for LED lamp beads can prolong the life of the LED lamp beads. At the same time, it directly integrates the light-emitting module to form an integrated lamp bead, which avoids dividing or arranging the light source on the substrate On, making the spectrum more uniform, more conducive to the growth and development of agricultural plants.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to an LED driving power supply circuit. Background technique [0002] At present, most of the agricultural lighting fixtures on the market use a constant current source to drive the whole lamp, and the use of a constant current source or a constant voltage source for driving has the following defects: [0003] Driven by a constant current source: [0004] 1. The arrangement of LED lamp beads and the type of lamp beads must match the constant current source; [0005] 2. After the constant current source is determined, the current power of the LED lamp bead of the lamp is determined, which may easily cause a mismatch between the power of the LED lamp bead and the radiator, resulting in the need to redesign the radiator or customize the constant current source; [0006] 3. The brightness of LED lamps driven by constant current sources is uncontrollable, and a set of constant current ...
