Problems solved by technology

However, the control of the lateral light intensity and lateral angle of the above-mentioned LEDs is not ideal. Therefore, when the LEDs are to form a backlight module, the array spacing of the LEDs is also limited within a certain distance to avoid problems such as insufficient brightness and uneven brightness. However, such a solution results in an increase in the number of LEDs and an increase in cost

Abstract

The invention provides a light-emitting diode which comprises a light-emitting diode chip, a substrate structure, a fluorescent powder layer and a lens, wherein the substrate structure is provided with a concaved groove so that the light-emitting diode chip and the fluorescent powder layer can be arranged in the concaved groove at the same time; the lens is arranged on the substrate structure and provided with a curve side wall, the top of the lens is provided with a flat panel and an inverted cone-structure female cone is arranged in the center of the top.

Description

technical field [0001] The invention provides a light-emitting diode and its related backlight module, especially a light-emitting diode with a lens (lens), so that the light-emitting diode has a side light field and a related backlight module. Background technique [0002] In recent years, the application fields of light emitting diodes (hereinafter referred to as LED (light emitting diode)) have been continuously developed. LED is cold light emitting, which has the advantages of low power consumption, long component life, no need to warm up the lamp time, and fast response speed. In addition, it is small in size, resistant to vibration, suitable for mass production, and can be easily made into a very small or Advantages such as array-style components. Light-emitting diode (LED) devices often need to match the beam pattern, view angle, or light output angle in order to meet the requirements of the application; therefore, when the LEDs are arranged in a matrix, it is necess...
