Abstract

A flexible linear LED light source relates to the technical field of LED photoelectrical display and is characterized in that: a LED chip (4) is adhered to the plane of a flexible circuit board (1) through silver coating, and is connected with the flexible circuit board (1), thus forming a electricity conductive layer (7). Aluminum wires (5) or golden wires are used to weld the electrode of LED chip (4) to the flexible circuit board (1). The chip (4) and aluminum wires (5) are wrapped by epoxy resin on the plane of the flexible circuit board (1), which forms a protection layer (6) for a light source point (3) in case of vibration and humidification. The utility model has the following advantages: its structure brings into full play the feature of flexible circuit, able to constitute various pictures by bending and can be used to produce background light of different shapes and parts and as picture sources of, thus dispensing with formation cost of rigid circuit board and saving middle materials. In addition, the utility model can be used repeatedly, thus prolonging the service life.

Description

Flexible line style led light source

Affiliated technical field

The utility model relates to LED photoelectric display technology manufacturing neck city, relates in particular to a kind of flexible line style led light source.

Background technology

Existing LED luminescent device must be welded on the rigidity wiring board, and is can't be arbitrarily crooked, pieces together the picture group case, and even wastes a large amount of wiring board materials during as the scene background.

Goal of the invention

The purpose of this utility model is at above-mentioned defective, a kind of new technical scheme is provided, the LED luminescence chip is combined with FPC, length as required is cut into bar shaped, can be many times crooked arbitrarily, distortion, can conversion with the occasion difference, the shaping expense of having removed the rigidity wiring board from, saved intermediate materials, and can repeatedly use.

Summary of the invention

The utility model is achieved by the following technical solution; chip in the LED luminescent device is connected on the FPC with elargol; connect the loop with aluminium, gold thread; and with the chip in the epoxy resin sealing environmental sealing luminescent device and aluminium, gold thread; make it solidify to form a protective layer; on FPC, form a complete light source point, to making the led chip can be luminous on FPC.Establish several light source points with series-parallel system, between FPC, be provided with power interface, by each light source point is point, line, surface and the various pattern that light source is formed in the unit, light source as a setting, and use as lamp band pattern, FPC can be made into different length as required, and can splice arbitrarily, gives full play to the flexible of FPC and the facility that pattern is formed.

The effect of invention

The advantage of technical solutions of the utility model is, its structure has been given full play to the characteristic of flexible circuitry, the various patterns of composition that can be crooked, can use bias light with different shapes and position, and pattern light source, save the cost of the common rigid wiring board of former use greatly, prolonged service life of the present utility model greatly.

Description of drawings

The utility model is further described in conjunction with the accompanying drawings with embodiment.

Accompanying drawing 1 is a floor map of the present utility model,

Accompanying drawing 2 is a side schematic view of the present utility model,

Accompanying drawing 3 is the structure for amplifying schematic diagram of the utility model light source point,

Accompanying drawing 4 is an electric diagram of the present utility model.

Wherein: (1) is FPC; (2) be resistance; (3) be light source point; (4) be chip; (5) be aluminum steel; (6) be protective layer; (7) conductive layer; (8) power interface.

As shown in drawings; the utility model is led chip (4) to be adhered to elargol on the plane of FPC (1) be connected with FPC (1); form a conductive layer (7); with aluminum steel (5) or gold thread; the electrode of welding led chip (4) is to FPC (1); so that going up at wiring board (1), chip (4) forms the loop; with epoxy resin with chip (4); aluminum steel (5); environmental sealing is on FPC (1) face; form the protective layer (6) of light source point (3); in the hope of shockproof; the bag of waterproof protects; be provided with power interface (8) at FPC (1); connecting power supply just can make led chip (4) go up luminous at FPC (1); between the upward every economize on electricity resistance of FPC (1) (2), establish several light source points (3); as shown in Figure 4; use series-parallel method of work; resistance (2) current limliting in addition in the line; so when adding electric current; there is light source point (3) beginning of led chip (4) luminous; the light source point of each bunchiness (3) is gone up luminous at FPC (1), unlimited prolongation can form a little; line; face and various pattern effect.

Claims

1, a kind of flexible line style led light source; comprise FPC (1); it is characterized in that: chip (4) is adhered on the plane of FPC (1); be connected with FPC (1), form a conductive layer (7), with aluminum steel (5) or gold thread; the electrode of welding chip (4) is to FPC (1); with chip (4), aluminum steel (5), environmental sealing is on FPC (1) face with epoxy resin, and the protective layer (6) that forms light source point (3) protects in the hope of bag shockproof, waterproof.
