Abstract

The invention relates to an LED (Light Emitting Diode) light source with low voltage and energy saving, which comprises a power supply converter and a light emitting body, wherein the power supply converter and the light emitting body are in a split structure; the direct current output of the power supply converter has safe voltage, and the power supply converter is at least correspondingly connected with the positive and negative electrodes of the light emitting body through wires; the light emitting body is formed by connecting a copper-clad plate and multiple paths of LEDs with high brightness in parallel; the LEDs are welded on the copper-clad plate; and the number of each path of the LEDs in series is 1-12. The LED light source provided by the invention has the advantages that a part of the light emitting body has low safe voltage and good safety performance; an accumulator or a wind power or solar energy power supply can be used as a power supply, and the application range is wide; because the light emitting body does not contain the high voltage of a mains supply, the requirements for an application environment are greatly lowered, and the light emitting body can be used indoors and outdoors, thereby greatly expanding the application occasions of the light emitting body; the power supply converter and the light emitting body are independently arranged, and one power supply converter can be configured with multiple light emitting bodies, thereby lowering the cost of the power supply converter; the general assembly structure of the light emitting body is simplified; and the light emitting body is fully utilized in the service life range, thereby lowering the service cost.

Description

Low-voltage energy-saving LED light source technical field The invention relates to an LED light source, in particular to a low-voltage energy-saving LED light source, which can be used as lighting and motor vehicle lighting or signal lights, such as indoor and outdoor lighting, and lighting in special environments such as high humidity and underwater. Background technique In order to use the mains power supply in the existing LED light source, a switching power supply is assembled on the luminous body, and the mains power (AC220V) is stepped down and converted into a DC power supply, that is, the luminous body (LED) and the switching power supply are combined into one, and directly connected to the market. electrical connection. Although this structure is convenient to use, it has the following disadvantages: 1. Poor safety: the luminous body (including switching power supply) is directly connected to the mains, and there are potential safety hazards during installation...
