Technical Field

[0001] The invention relates to the technical field of lighting equipment, and in particular to a high-efficiency lamp tube. Background Art

[0002] As an energy-saving bulb, LED lamp not only has low power consumption and good lighting effect, but also has low color temperature and emits white light, which is not very irritating to the human eye. Therefore, it is widely used by people. However, LED lamp is composed of multiple lamp beads fixed in the lamp tube.

[0003] At present, the lamps in the industry are all ordinary round tubes with dispersed light and low illumination. There are usually plugs at both ends of the lamp tubes. In order to avoid excessive temperature inside the lamp, some lamps have heat dissipation holes on the plugs.

The optical focusing stripes are provided to facilitate the light emitted by the lamp beads to refract a part of the light when passing through the water chestnut, and a part of the light can be seen outside the PC tube, thereby ensuring a large luminous surface of the lamp body. Another part of the light is reflected back and concentrated on the positive light-emitting surface of the PC cover to increase the front light intensity. The dust-proof component is set to facilitate the filtering of dust when the outside air enters the PC tube to prevent the PCB board in the PC tube from being covered by dust. The heat dissipation holes are set to facilitate the outside air to enter the PC tube to cool its internal components.

[0008] Preferably, the mounting frame is fixedly connected to the end face of the second plug, the central through-hole of the mounting frame is connected to the heat dissipation hole, a placement groove is provided on the side surface of the mounting frame away from the second plug, a filter sponge is placed in the placement groove, a first slide groove is provided on the side surface of the mounting frame away from the second plug, a second slide groove is provided on the upper surface of the first slide groove, a slide hole is provided on the upper surface of the mounting frame, and the slide hole and the second slide groove are connected.
