Constant-power linear IC parallel circuit

Abstract

The invention discloses a constant-power linear IC parallel circuit, and relates to the technical field of ceiling lamps. The constant-power linear IC parallel circuit comprises a power supply input end, a bridge rectifier circuit, a first constant-power linear IC, a second constant-power linear IC, a first light emitting module, a second light emitting module, a third light emitting module, a fourth light emitting module, a fifth light emitting module and a sixth light emitting module, and is characterized in that the bridge rectifier circuit is connected to the power supply input end; the first light emitting module, the second light emitting module, the third light emitting module, the fourth light emitting module, the fifth light emitting module and the sixth light emitting module are all formed by a plurality of serially connected LED lamp beads. The constant-power linear IC parallel circuit has the beneficial effects that the circuit adopts the parallel linear ICs, the power is enabled to reach 24W, the power factor is greater than 0.9, and the load for a power grid is reduced. The constant-power linear IC parallel circuit has the main characteristics of long service life, low cost, and simple and convenient installation.

Description

technical field [0001] The invention relates to the technical field of ceiling lamps, and more specifically, the invention relates to a constant power linear IC parallel circuit. Background technique [0002] Existing LED ceiling lamps use strips or jigsaw panels to allow the light to pass through the diffusion cover evenly. During the production process, there are many screws or buckles to fix the PCB board, and there are many connecting lines, which will cause manual labor. Doubled, but the defect rate has risen in a straight line. Combining these problems and shortcomings will lead to a higher sales price of the whole lamp and difficulties in maintenance during use by customers. In addition, the power is low, the power factor is greater than 0.9, and the load requirements on the power grid are relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide a const...

Problems solved by technology

[0002] Existing LED ceiling lamps use strips or jigsaw panels to allow the light to pass through the diffusion cover evenly. During the production process, there are many screws or buckles to fix the PCB board, and there are many connecting lines, which will cause manual labor. The multiplied growth, but the defect rate has risen in a straight line. Combining these problems and shortcomings will lead to a higher sales price of the whole lamp and difficulties in maintenance during use by customers.

In addition, the power is low, the power factor is greater than 0.9, and the load requirements on the grid are relatively high.
