Abstract

The invention provides an alternating-current LED light source. The alternating-current LED light source comprises a substrate and a plurality of sets of alternating-current LED chips. The substrate plate comprises an aluminum oxide substrate, an insulating layer and a conducting layer which are successively arranged from bottom to top. The substrate further comprises alternating-current LED light source die bonding blocks. The insulating layer is a ceramic insulating layer. The conducting layer is provided with a positive electrode, a negative electrode and serially-connected circuits. The serially-connected circuits are arranged in the die bonding blocks. The insulating layer surrounds the alternating-current LED light source die bonding blocks and is fixed on the aluminum oxide substrate. The serially-connected circuits are electrically connected with the positive electrode and the negative electrode. The plurality of sets of alternating-current LED chips are mutually connected in parallel. Compared with the prior art, the alternating-current LED light source can directly work under an alternating-current power supply, and no internal drive power supply is arranged, so that the material cost and the manual installation cost are substantially saved, the size of the alternating-current LED light source is substantially reduced, and the occupied space is reduced in installation. The aluminum oxide ceramic-based substrate is adopted, the heat dissipation coefficient is high, and the heat stability is good.

Description

technical field [0001] The invention relates to the technical field of LED lighting, specifically, only AC LED light sources are used. Background technique [0002] Traditional LED lamps are powered by DC. To enable them to work directly under AC, the current method is to configure a driving power supply inside the lamp body to convert the input AC power into DC power for the LED to work. The structure of installing the driving power supply inside the LED lamp will cause high cost problems for the manufacturer, and there will be troublesome installation and long installation time during production. Larger, the installation takes up a lot of space, and the overall appearance is not beautiful. In addition, due to the configuration of the driving power supply, the driving power supply is easily damaged by static electricity, so the workability and longevity of this LED lamp cannot be guaranteed. Contents of the invention [0003] In view of the above problems, the present i...
