Abstract
The utility model discloses a light emitting diode (LED) fluorescent lamp, and aims to solve the technical problem of reducing manufacturing cost. The LED fluorescent lamp comprises a lamp tube and a circuit board strip with an LED lamp bead, wherein the circuit board strip is placed in the lamp tube. The circuit board strip is fixedly connected with an inner wall of the lamp tube through a fixing layer in the width direction of the circuit board strip and with the same curvature with the circumference curvature of the inner wall of the lamp tube. The circuit board strip is directly fixed on the inner wall of the lamp tube through the fixing layer, and therefore a metal support used for fixing the circuit board strip in an LED fluorescent lamp tube in the prior art is left out, and manufacturing cost of the LED fluorescent lamp is greatly reduced; and when an adhesive layer with good heat-conducting performance is adopted by the fixing layer, heat dissipation of the fluorescent lamp can also be improved. Light reflection films are further placed on an inner wall of the lamp tube and an outer wall of the lamp tube so as to ensure that light rays emitted to the back of the lamp tube by an LED lamp source are all sufficiently utilized because of reflection. Therefore, light-emitting luminance of the fluorescent lamp is correspondingly strengthened. In addition, cooling fins are additionally placed outside the tube, and heat dissipation effect of the lamp tube is further improved.
