Abstract

An LED module for use in a direct-type backlight module includes a printed circuit board, an LED arrange on the printed circuit board and electrically connected to the printed circuit board, and a lens covering the LED and fixed on the printed circuit board. A reflective layer is arranged on the printed circuit board. A semi-transparent surface is recessed and tampered from a top of a column-shaped protrusion at a center of the lens towards the LED. Part of light beams emitted from a center of the LED is refracted and diffused by the semi-transparent surface to an outside, and another part of the light beams emitted from a center of the LED is reflected by the semi-transparent surface to the reflective layer, and then reflected by the reflective layer to the outside.

Description

technical field [0001] The invention relates to a semiconductor structure, in particular to a light emitting diode module. Background technique [0002] Compared with traditional light sources, light emitting diodes (Light Emitting Diode, LED) have the advantages of light weight, small size, low pollution, long life, etc. As a new type of light source, it has been increasingly used in In various fields, such as street lights, traffic lights, signal lights, spotlights and decorative lights. [0003] Existing LED modules such as LED light bars generally include a circuit board and a plurality of LEDs mounted on the circuit board. The light emitting angle of the existing light emitting diodes is generally 120°, so in order to make the emitted light of the light bar uniform, a certain number of light emitting diodes must be installed in the light bar, and the interval between each adjacent two light emitting diodes should not be greater than the predetermined The numerical val...
