Embodiment

[0032] In the present invention, a plurality of LED modules 2 are connected in series through an ABS flame-retardant power supply box 1 to complete the function of the LED light box light source.

[0033] Such as figure 1 As shown, the ABS flame-retardant power supply box 1 is equipped with an AC / DC conversion circuit. To be precise, the circuit is set on an FR-4 epoxy resin circuit board, including pressure-sensitive resistance, a fuse connected between one end of the varistor and the mains, a thermistor connected between the other end of the varistor and the mains, a rectifier connected in parallel with the varistor, and the rectifier A step-down constant current circuit connected to the output end of the LED; the LED lamp bead is connected in series with the step-down constant current circuit. The step-down constant current circuit includes a filter capacitor C1 connected in parallel with the output terminal of the rectifier, a constant current chip connected in parallel w...

Abstract

The invention discloses an AC (alternating-current) under-penetrating waterproof LED module which comprises an ABS (acrylonitrile butadiene styrene) flame-retardant power box for bearing an AC / DC (direct-current) conversion circuit and at least five LED module bodies connected with the power box through module power lines. The AC / DC conversion circuit is arranged on an FR-4 epoxy resin circuit board, and waterproof heat-conductive silica gel is potted in the ABS flame-retardant power box. Each LED module body comprises a square PVC flame-retardant shell made of a PVC insulating material, four LED lamp beads arranged inside the PVC flame-retardant shell, connected with the AC / DC conversion circuit and distributed in a rectangle, and four PC lenses arranged on the PVC flame-retardant shell and in one-to-one correspondence to the LED lamp beads. Epoxy resin glue is potted in the LED module bodies. The problem that an LED lamp box cannot be connected with a mains supply directly and externally at present is solved; safety of the AC under-penetrating waterproof LED module is improved.

Description

[0001] technical field [0002] The invention relates to an LED light box, in particular to an AC bottom-through waterproof LED module. Background technique [0003] In recent years, the LED advertising sign industry has achieved rapid development. With the rising awareness of global energy conservation and the relatively high electricity price of traditional light sources, LED light sources are energy-saving and environmentally friendly. At the same time, they support the industry for national policies and promote the continuous introduction of LED light box light sources in the fields of commerce, construction, and advertising signs. Among them, the LED light box of the low-voltage module is widely used in the advertising signage industry due to its advantages such as low luminous heat, long life, and small size. [0004] At present, the advertising sign industry mainly uses low-voltage modules, which adopt the technical scheme of separating low-voltage DC power supply an...
