Abstract

The invention relates to a bar-shaped light emitting element, a backlight module equipped with the bar-shaped light emitting element and electronic equipment. The bar-shaped light emitting element comprises a fluorescent film layer, at least two LED chips, a substrate and a circuit board, wherein the at least two LED chips are arranged between the fluorescent film layer and the substrate, and the circuit board is perpendicular to a plane of a substrate surface on which the chips are arranged. Through arranging the circuit board perpendicular to the plane of the substrate surface on which the chips are arranged, a side surface of the substrate is facilitated to connect with an external power-supply power or the circuit board, the size of the electronic equipment can be reduced substantially, light and thin development demands of the electronic equipment can be satisfied, and user experience is improved. Light emitted by the LED chips can be prevented from shielding, and light emitting intensity and uniformity are guaranteed; the backlight module and the electronic equipment have advantages of simple manufacturing process, low manufacturing cost, uniform emitting light without dark areas and high intensity.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electronic products, in particular to a strip-shaped light-emitting element, a backlight module and electronic equipment. [0003] 【Background technique】 [0004] With the development and maturity of LED technology, the performance of LED is improving day by day, and the research and development of LED technology is becoming more and more active, and LED has also been used more and more. [0005] At present, the application range of LED electronic equipment is becoming wider and wider, and people's requirements for the quality of LED electronic equipment are also getting higher and higher. However, in existing LED electronic equipment, LED chips, substrates, circuit boards or external power supplies are generally packaged in stacks, and soldering wires are used to electrically connect the LED chips to the substrate, so it takes up more space and the overall volume is too large to adapt to People's demand f...
