Example Embodiment

[0024] Example 1

[0025] figure 1 It is a schematic plan view of the present invention, figure 2 It is an enlarged view of the side structure of the present invention. like figure 1 and figure 2 As shown, a linear LED light source has a three-layer structure, which are: reflective paper 100, aluminum foil layer 200 and thermally conductive double-sided adhesive tape 300, which are stacked sequentially from top to bottom, and the surface of the uppermost layer is reflective paper 100.

[0026] like figure 1 As shown, the reflective paper 100 is provided with a plurality of light-transmitting holes 110, the LED chip 220 and the protective film 240 formed by transparent glue form a protruding light source part 250, and is arranged in the light-transmitting hole 110, and the surface of the LED chip 220 is also sprinkled. There are phosphors, and the protective film 240 formed by phosphors and transparent glue increases the light transmittance of the LED light source. At th...

Example Embodiment

[0034] Example 2:

[0035] Image 6 It is a schematic plan view of the aluminum foil layer in Example 2. like Image 6 As shown, the LED chips 220 of the present invention can be connected not only in series but also in series. After the series connection is adopted, it is not possible to use the aluminum foil strip 210 as a whole. Therefore, the aluminum foil layer 200 will be composed of individual pieces of aluminum foil 260 instead of the rectangular strip structure in the first embodiment. A plurality of LED chips 220 are adhered to corresponding numbers of aluminum foils 260 with a transparent adhesive, and the distance between the aluminum foils 260 is about 0.3 mm, and then the LED chips 220 are connected through connecting wires 230 to form a series connection. All the other parts are with embodiment 1.

Abstract

The invention discloses a linear LED light source which comprises reflective paper, an aluminum foil layer and heat conduction double face adhesive tape. The reflective paper, the aluminum foil layer and the heat conduction double face adhesive tape are overlapped from top to bottom sequentially. The aluminum foil layer comprises aluminum foil strips, an LED chip and connecting wires. The linear LED light source is of a linear structure and wide in application, good in heat dissipation performance, capable of satisfying the requirements for different lengths on various occasions and beautiful due to ultra-thin design. Meanwhile, the linear LED light source has flexibility so that the linear LED light source can be freely bent by a user and breakage of the linear LED light source does not need to be worried. A large number of production materials are saved, so that production cost is greatly reduced.

Description

technical field [0001] The invention relates to an LED light source, in particular to a linear LED light source. Background technique [0002] The linear LED light strip is soft and can be curled like a wire; it can be cut and extended; the bulb and the circuit are completely covered in flexible plastic, which has good insulation and waterproof performance and is safe to use; it has strong weather resistance; it is not easy to break and use Long service life; easy to make graphics, text and other shapes; it has been widely used in decoration and lighting of buildings, bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertisements, signs, signs, etc. A new type of LED with many advantages, but it also has a very fatal weakness. Although the linear LED light strip is soft and can be bent, it has poor toughness. During the installation process, the product will break due to excessive force or excessive bending. At the same time, becaus...
