Abstract
A lens module lamp tube comprises lamp caps, a PC (poly carbonate) outer casing, an aluminum profile base, SMD (Surface-Mounted Device) LED (light emitting diode) light sources, and a PCB (printed circuit board) bottom plate, wherein the PC outer casing is buckled with the aluminum profile base to form a lamp tube shell, the lamp caps are arranged on the two ends of the lamp tube shell, the PC outer casing and the PCB bottom plate are fixed on the aluminum profile base in a clamping groove mode, a plurality of lens modules are uniformly distributed on the PCB bottom plate, the lens modules comprise backlight lenses and the SMD LED light sources which are welded on the PCB bottom plate, and the backlight lenses correspondingly cover the outside of each SMD LED light source, and are mounted on the PCB bottom plate. The combination structure of the backlight lenses and the SMD LED light sources is adopted by the utility model, so that the number of the SMD LED light sources is reduced under the condition of not influencing the illuminance. Under the condition that hundreds of SMD LED light sources are needed by a common lamp tube, only twenty to thirty SMD LED light sources are needed by the lens module lamp tube. The light utilization rate of LEDs can be exerted to the utmost extent by adopting the backlight lenses, the illumination effect is good, and the problem of an occulting light area is avoided. Furthermore, the cost of a product is greatly reduced, and better market value is realized.
