The invention relates to the field of LED lighting, and particularly to an LED light bar. The LED light bar comprises a bottom adhesive layer formed on the top surface of a transparent substrate; an LED crystal with two luminous sides is arranged on the top surface of the bottom adhesive layer; and fluorescent powder is mixed in the bottom adhesive layer. During the lighting time, the laterally emitted part of the light emitted by the bottom surface of the LED crystal after being transformed into white light by the fluorescent powder of the bottom adhesive layer is then refracted to the side surface of the bottom adhesive layer by the bottom adhesive layer and emitted out. Therefore, the light bar can realize the luminous side surface without dispensing the side surface of the transparent substrate. In the aspect of the production technology, the LED lighting bar changes the traditional conventional method of firstly performing die bonding and then dispensing; when the LED lighting bar is produced, the bottom adhesive layer is firstly formed by dispensing the LED substrate, and then die bonding is carried out on the bottom adhesive layer, so that light emitted by the bottom surface of the LED crystal can be emitted out from the side surface of the bottom adhesive layer, the LED light bar can achieve an effect of giving out light by the side surface, and naturally dispensing for the side surface of the transparent substrate is unnecessary. Aiming at the improvement of the abovementioned structure and process, the invention respectively provides an epoxy encapsulation adhesive and organic silica gel used for the bottom adhesive layer and the top adhesive layer.
