Embodiment 1

[0023] refer to Figure 1-4 : AC LED lighting light source module, including heat dissipation plate 1, AC LED tube core 9, described heat dissipation plate 1 is made of high thermal conductivity material, is arranged with heat conduction area 10 and printed circuit board with circuit printed on it, described The AC LED die 9 includes a heat sink 3 with LED crystal grains 2 bound on the upper surface, a high temperature resistant insulating shell 4 wrapped on the heat sink 3, and two For the electrode 5, the bottom end of the heat sink 3 is closely attached to the heat conduction area 10 of the heat sink 1, and the upper end is exposed to the insulating casing 4; the external end of the electrode 5 passes through the The insulating casing is connected to an AC power supply, and the inner terminal of the electrode 5 is bound with at least bare-core electronic components 6 for AC-DC conversion, and the LED crystal grain 2 is electrically connected to the bare-core electronic comp...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that there are three pairs of electrodes 5, two pairs of the three pairs of electrodes are bound with bare core electronic components 6, and the external terminals of these two pairs of electrodes are connected to an AC power supply As an input, the LED grain 2 is connected to the bare core electronic components 6 on the two pairs of electrodes through wires, so as to realize the electrical connection between the LED grain and the bare core electronic components according to the requirements of various circuits ; In addition, the LED grain 2 is electrically connected to the inner terminal of another pair of electrodes not bound with the bare core electronic components 6 through a wire, and the pair of electrodes can be connected internally through the printed circuit on the heat sink, and at the same time External components can also be connected, such as connecting a filter circuit to make the waveform smoother ...

Embodiment 3

[0034] The difference between this embodiment and Embodiment 1 is that no optical lens 7 is arranged at the upper end of the insulating housing 4, and in this embodiment, the fluorescent powder packaging material is covered in the annular groove 8 of the insulating housing, and then the The surface of the LED grain is covered with phosphor powder encapsulation material. The blue light emitted by the LED crystal grain 2 is mixed with the yellow light emitted by the covering layer of the phosphor packaging material to form white light to be emitted. Setting the ring-shaped groove can facilitate the shaping of the phosphor packaging material, so as to better control the light-emitting angle. Other structures and implementations of this embodiment are completely the same as those of Embodiment 1.

Abstract

The invention relates to an AC (alternating current) LED lighting source module, which comprises a heat dissipation plate and an AC LED tube core. The AC LED tube core comprises a heat sink with a LED crystal grain arranged on the upper end face, an insulation shell wrapped on the heat sink and at least one pair of electrodes penetrated on the insulation shell, wherein the bottom end of the heat sink is stuck on the heat dissipation plate, and the upper end of is exposed out of the insulation shell; and an external connection end of the electrode penetrates through the insulation shell and is connected with an alternating current power supply, an internal connection end of the electrode is bound with a bare chip electronic component which is subjected to AC-DC (direct current) conversion at least, the LED crystal grains are electrically connected with the bare chip electronic component through a lead, and non-electric connection parts between the bare chip electronic component and the LED crystal grain are isolated through the insulation shell and other encapsulation materials. The AC LED lighting source module has the advantages of small volume, compact structure and an integral encapsulation of an AC-DC conversion driving chip, the bare chip electronic component and the LED crystal grain.

Description

technical field [0001] The invention relates to an LED lighting light source module with AC power supply. Background technique [0002] When the existing LED lighting source is used, it needs to match the AC-DC conversion drive device (including AC-DC conversion device and constant current, constant voltage drive device). , The constant voltage driving device drives the LED to emit light. The above-mentioned AC-DC conversion drive device and the LED are two separate components, which brings about the problem that the overall volume is large, cumbersome, and inconvenient to use. Contents of the invention [0003] In order to solve the problems of large size, cumbersome and inconvenient use caused by the need to connect an independent AC-DC conversion drive device when using the existing LED light source, the present invention proposes a small-volume, compact-structure AC-DC conversion drive An AC LED lighting source module in which chips and LED grains are integrated. ...
