Abstract

The invention is suitable for the field of electric lamps and provides an LED signal lamp, a PCB (Printed Circuit Board) substrate structure thereof and a light source assembly. In the invention, the PCB substrate structure of the LED signal lamp is optimized, for example, the periphery of the PCB substrate is provided with a series of welding spot groups used for welding LEDs, and the welding spot groups are connected in series; the middle part of the PCB substrate is provided with an anode pad and a cathode pad, and the positions of the pads are respectively provided with a through hole; and the PCB substrate and a lamp body are electrically connected together through two conducting rods respectively passing through the through hole of the anode pad position and the through hole of the cathode pad position. In this way, the LED signal lamp adopting the PCB substrate structure is convenient to assemble and maintain, and after the LED signal lamp is vibrated, the PCB substrate is not easy to loosen; and stable electric connection can also be formed between the conducting rods and the PCB substrate so as to avoid the phenomenon that the LED signal lamp is extinguished because of power down.

Description

technical field [0001] The invention belongs to the field of electric lamps, and in particular relates to a PCB substrate structure of an LED signal lamp, a light source assembly and an LED signal lamp. Background technique [0002] LEDs are widely used in signal lamps due to their low energy consumption and long service life. Existing LED signal lights such as Figure 1a with 1b As shown, it includes a lamp body 100 and a light source assembly 102, and the light source assembly 102 is engaged with the slot 101 provided on the lamp body 100, and the electrical connections between the light source assemblies 102 are connected together by wire welding. Because the light source assembly 102 of the existing LED signal lamp and the lamp body 100 are fixedly connected by a clamping method, the assembly operation of this fixed connection method is complicated, and it is easy to loosen when subjected to long-term vibration; and the electrical connection between the light source ass...
