Abstract

An LED tube light that emits light on two sides, comprising LEDs (11), a current limiting resistor, a flexible circuit board (1), a twisted metal cable, and cover layers (2 and 4). The cover layers (2 and 4) are covered on the peripheries of the LEDs (11), of the current limiting resistor, of the flexible circuit board (1), and of the twisted metal cable. The LEDs are welded onto both sides of the flexible circuit board (1). The tube light allows for greatly increased light-emitting angle of a light body, allows the light body to achieve 360-degree light-emitting effect, and is applicable as decorative lighting in scenarios such as spatial-hanging or three-dimensional patterns and styles. The flexible light also has the advantages of a simplified structure, a simplified manufacturing process, and reduced costs.

Technical field

The utility model relates to a decorative lamp, in particular to a double-sided illuminated LED hose lamp.

Background technique

LED hose lamps are popular among people because of their energy saving, long life, uniform and soft lighting, and strong bendability. They have been widely used in urban nightscape decoration, commercial signboards, architectural shape decoration and so on.

The existing LED hose lamp has the following structure: the chip LED is soldered on the flexible circuit board to form an illuminant, and then a cladding layer is coated on the periphery of the illuminator. Since the existing LED hose lamps are all single-sided illumination, the whole body can not be illuminated, so the application is not good when used in decorative lighting places such as space suspension or three-dimensional pattern modeling.

In order to achieve the above object, the solution adopted by the present invention is:
A double-sided light-emitting LED hose lamp comprising an LED, a current limiting resistor, a flexible circuit board, a metal strand, and a cladding layer, the cladding layer covering the LED, the current limiting resistor, the flexible circuit board and the metal strand The periphery of the wire is characterized in that the flexible circuit board is soldered with LEDs on both sides.

Further, the flexible circuit board is soldered with a current limiting resistor on at least one side of the two sides.

Further, the LEDs on both sides of the flexible circuit board are spaced apart or aligned.

Further, the metal strands are electrically connected to the flexible circuit board and arranged side by side along the length of the flexible circuit board.

Further, the covering layer comprises an inner covering layer and an outer covering layer.

Further, the metal strand and the inner cladding are integrally formed by an extrusion technique.

Further, the inner covering layer is a flexible strip having a cavity inside and a slit extending through the length thereof.

Further, the cavity cross-sectional shape of the inner cladding layer includes a circular shape, an elliptical shape, a rectangular shape, a D shape, and a trapezoidal shape.

Further, the cross-sectional shape of the outer covering layer includes a circular shape, an elliptical shape, a rectangular shape, a D shape, and a trapezoidal shape.

Further, the coating layer is made of a transparent or light transmissive flexible material containing a light-mixing substance.

The utility model has the following beneficial effects: the utility model effectively increases the illumination angle of the lamp body by welding the LED on both sides of a flexible circuit board, and adds the astigmatism substance inside the inner and outer cladding layers or The refraction of light inside the lamp body enables the lamp body to achieve 360-degree illumination effect, and can be applied to decorative lighting places such as space suspension or three-dimensional pattern modeling; on the other hand, the utility model has the advantages of simple structure and simple production process. Low cost and other advantages.

detailed description

Example 1

As shown in Fig. 1, the LED and the current-control element are soldered on the two sides of the flexible circuit board in a staggered manner; as shown in Fig. 2 and Fig. 3, the metal strand is embedded in the inner cladding layer and integrated by extrusion molding technology. Forming, the inner coating layer is a flexible rubber strip with a cavity inside and a slit through the length thereof. In the production process, the slit is first opened, and then the flexible circuit board with the LED and the current limiting resistor is welded. The slit is laterally inserted into the cavity of the inner cladding layer, and the position of the flexible circuit board is adjusted, and then a small slit of the inner cladding layer is cut at the place where the welding is required, the metal stranded wire is exposed, and the metal is twisted by the wire. The wires are electrically connected to the flexible circuit board. Finally, an outer coating layer is sealed on the outside of the inner coating layer by an extrusion molding technique.

Example 2

As shown in FIG. 4, the LEDs and the current-control elements are soldered on both sides of the flexible circuit board in an aligned manner; as can be seen from FIG. 5, the lamp bead distribution on the flexible circuit board is different in this embodiment. The structure and production process are the same as in the first embodiment, I will not repeat them here.

Further optimized, the inner cladding layer and the outer cladding layer of the utility model are made of a flexible transparent or light-transmitting material, and contain a light-mixing substance, so that the lamp body emits softer and uniform light; As shown in FIG. 6, the inner cladding cavity and the outer cladding of the present invention have various shapes, and various application structures can be obtained by combining various shapes.

The above embodiments are only used to illustrate the technical solutions of the present invention, and do not constitute a limitation on the scope of protection of the present invention. The scope of protection of the present invention also includes those skilled in the art who do not make creative work on the present invention. Various modifications and replacements made below.
