Embodiment

[0025] Such as figure 1 , figure 2 and image 3 As shown, the AC high-voltage double-sided LED light bar is mainly composed of a transparent cover and protective covers at both ends. The transparent cover is made of PC material, which is not only environmentally friendly, but also durable and non-deformable. Strong adaptability; the whole is a long tubular structure with LED light strips installed inside. The LED light bar is composed of FR-4 epoxy resin circuit board and LED lights. The FR-4 epoxy resin circuit board is equipped with AC and DC conversion circuits, and the LED lights are installed on the front and back of the FR-4 epoxy resin circuit board. On both sides, when working, the whole product can realize double-sided light emission, which not only increases the irradiation range, but also improves the advertising effect.

Abstract

The invention discloses an AC (alternating current) high-voltage double-side LED lamp bar. The AC high-voltage double-side lamp bar comprises an elongated bar-shaped transparent cover, protecting caps and an LED lamp bar body, wherein the protecting caps are fixed at two ends of the transparent cover, and the LED lamp bar body is fixed in the transparent cover. The LED lamp bar body comprises an FR-4 epoxy resin circuit board and LED lamps, wherein the FR-4 epoxy resin circuit board is provided with an alternating-current and direct-current conversion circuit, and the LED lamps are arranged on the front side and the back side of the FR-4 epoxy resin circuit boards. Meanwhile, waterproof heat-conduction silica gel is filled in the protecting caps. The AC high-voltage double-side LED lamp bar is skillful in design, simple in structure, convenient to realize and low in cost, is remarkably higher in comprehensive performance as compared with the prior art, and has good market prospect.

Description

[0001] technical field [0002] The invention relates to a double-sided LED light, in particular to an AC high-voltage double-sided LED light bar. 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 powe...
