The invention discloses a light guide bar-type LED (light emitting diode) daylight lamp, comprising a lamp tube, lamp heads arranged at two end parts of the lamp tube, a light guide bar, a refractive film and two rows of LED light bars; the refractive film is adhered to the bottom face of the light guide bar; the two rows of LED light bars are formed by a PCB (printed circuit board) and LED lights welded on the PCB; the LED light bars are respectively arranged on two sides of the light guide bar; the upper face of the light guide bar is a smooth face while the middle part of the bottom face is arched; multiple V-shaped ridges are distributed on the bottom face of the light guide bar; the V-shaped ridges have the heights of 0.1-0.3mm and the included angles of 107-125 degrees; the multiple V-shaped ridges are parallel; the distances between adjacent V-shaped ridges are arrayed in a gradually sparser mode from the light faces at two sides to the central position; and the heights of the multiple V-shaped ridges are arrayed in a gradually higher mode from the lighting faces at two sides to the central position. Compared with the prior art, the light guide bar-type LED daylight lamp has the efficacies of high lighting, no light and dark light spots at the lighting face and no glaring.
Description
technical field [0001] The invention relates to the field of LED fluorescent lamps, and more specifically relates to a light-guiding strip-type LED fluorescent lamp, which has the effects of saving energy and improving the light output rate. Background technique [0002] Traditional LED fluorescent lamps generally include a PCB circuit board, a plurality of LED lamps, a PC cover and a heat dissipation cover. The plurality of LED lamps are all arranged on the circuit board and electrically connected with the circuit board. The heat generated by a plurality of LED lamps can be dissipated outward through the heat dissipation cover, and the PC cover plays the role of light guide and is also connected with the heat dissipation cover to form the shell of the entire LED fluorescent lamp. [0003] The plurality of LED lights are generally single or double rows of LED lights welded on the PCB circuit board. The single or double rows of LED lights are close to the platform surface in ...
