Example Embodiment

[0033] The present invention provides a light emitting device directly driven by alternating current, integrating a rectifier circuit and a light emitting diode, and a related manufacturing method thereof. Please note that the rectifier circuit integrated in the present invention includes a bridge rectifier circuit, other full-wave rectifier circuits, and a half-wave rectifier circuit. In other words, the present invention does not specifically limit the type of rectifier circuit, but for the convenience of description below, the bridge rectifier circuit is mainly used as an example for description. In addition, the focus of the present invention is not to integrate the rectifier circuit and the light-emitting diode load circuit into the circuit shown in Figure 1a. Such circuit architectures are mostly conventional technologies. The focus of the present invention is the integrated circuit that implements this circuit. Architecture.

[0034] There are basically no special restricti...

Abstract

The invention is concerned with the illumination equipment and the corresponding method for the alternating current direct drive, the conformity commutating circuit and the light-emitting diode (LED). The LED illumination equipment includes the base-board, the top base-board, and the bottom base-board. The bottom base-board uses the manufacture of the integrate circuit to implement the commutating circuit, and sets the fit electric point on the surface. The top base-board uses the manufacture of the integrate circuit to implement the several LED in it by the arrangement mode of insulating independent N*M matrix. Between the N*M of LED forms the fit circuit by the connection of the lead. The top base-board and the bottom base-board are opposite, and finish the electric connection between the commutating circuit and the LED by the metal protruding block.

Description

technical field [0001] The present invention relates to a light-emitting device with light-emitting diodes as a light source, in particular to a light-emitting diode light-emitting device with a rectifier circuit disposed in a submount and a related manufacturing method. Background technique [0002] The basic way of using light-emitting diodes is to apply an appropriate forward DC voltage to the light-emitting diodes to drive the electrons and holes of the light-emitting diodes to combine to release photons. As the use of light-emitting diodes gradually expands to household and outdoor lighting, there are more and more applications that need to directly drive light-emitting diodes with alternating current. But when AC voltage is applied to the light-emitting diode, the excessive reverse voltage can easily damage the light-emitting diode. Therefore, a common solution is to use a transformer or a step-down circuit to reduce the AC voltage to an appropriate range that the LED...
