Technical Field

[0001] The utility model application relates to the technical field of LED lamp tubes, in particular to a spiral LED lamp tube with high light transmittance and high illumination. Background Art

[0002] LED light tubes are also commonly known as lamp tubes (fluorescent tubes). Their light source uses LED as the light source. They use light-emitting diodes as the light source, which has higher lighting efficiency, is more energy-efficient, has a longer service life, and is more environmentally friendly. They do not produce ultraviolet light, infrared light and other radiation, do not contain harmful substances such as mercury, generate less heat, and effectively avoid mosquitoes surrounding the light source. They are generally used for general lighting, indoor lighting in office buildings, shopping malls, restaurants, schools, homes, factories, etc.

[0003] After long-term use, many existing spiral LED lamp tubes are not equipped with lampshades to ensure light transmittance, which also causes dust to accumulate on the surface of the lamp tube. The dust and dirt deposited on the lamp and radiator will hinder the dissipation of heat, thereby affecting the brightness of the LED lamp, resulting in the lamp tube being unable to maintain high light transmittance and high brightness for a long time. At the same time, excessively high temperature will reduce the life and brightness of the LED lamp. Summary of the invention

[0007] Furthermore, the inner layer of the main tube sleeve of the lamp tube is a high-transmittance acrylic plate, and the outer layer is a high-strength light-transmitting polycarbonate plate. The tops of both sides of the main tube sleeve of the lamp tube are provided with transparent reflective plates in an "eight" shape for reflecting and focusing light from the spiral lamp body.

[0008] Furthermore, an inverted "convex" shape cooperating with the movable sleeve block is provided inside the slide rail box, and the length of the screw rod is equal to the length of the lamp tube body.

[0009] Furthermore, the fixed sliding sleeve is configured as a ring that matches with the main body of the lamp tube, and a threaded hole that matches with the screw rod is provided inside the movable sleeve block.

[0010] Furthermore, a connecting rubber pad is glued and fixed to the outer surface of the cleaning sponge, a fixing slot cooperating with the connecting rubber pad is provided inside the fixing sleeve, and the connecting rubber pad is engaged inside the fixing slot.

[0011] Furthermore, the length of the cleaning sponge is equal to the circumference of the outer ring of the lamp tube body, the edges at both ends of the cleaning sponge are both configured to be arc-shaped, and the length of the cleaning sponge is greater than the length of the fixed slot.

[0012] Furthermore, the connecting rubber pad and the fixing slot are both configured as strips that match the cleaning sponge, the connecting rubber pad and the fixing slot are both trapezoidal in cross-section, and the thickness of the connecting rubber pad is less than the thickness of the cleaning sponge.

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The top of the inner side of the tube sleeve of the lamp tube body 1 is provided with a transparent reflective plate 11 in an "eight" shape, which is used for the spiral lamp body to reflect and focus light. The lamp tube body 1 is installed inside the support frame 2, and a servo motor 3 is provided at one end of the support frame 2. A slide rail box 4 is fixed on the top surface of the support frame 2 above the lamp tube body 1. The slide rail box 4 is provided with a movable sleeve block 6. An inverted "convex" shape, the length of the screw rod 5 is equal to the length of the lamp tube body 1, and the inside of the slide rail box 4 is rotatably connected with the screw rod 5 through a bearing, the output end of the servo motor 3 rotates through the support frame 2 and is fixed on the screw rod 5, and a movable sleeve block 6 is threadedly sleeved on the screw rod 5, and a fixed sleeve 7 is fixed at one end of the movable sleeve block 6 extending to the outside of the slide rail box 4, and a cleaning sponge 8 is detachably connected to the inside of the fixed sleeve 7, and the fixed sleeve 7 is arranged in a ring shape that cooperates with the lamp tube body 1, and a threaded hole that cooperates with the screw rod 5 is opened inside the movable sleeve block 6.

[0023] Specifically, when it is necessary to wipe the outer surface of the lamp tube body 1, turn on the servo motor 3, so that the servo motor 3 runs and drives the screw rod 5 to rotate. When the screw rod 5 rotates, it drives the movable sleeve block 6 to move inside the slide rail box 4, thereby driving the fixed sleeve 7 to move on the lamp tube body 1. When the fixed sleeve 7 moves, it can drive the cleaning sponge 8 to wipe the outer surface of the lamp tube body 1, thereby removing dust on the outer surface of the lamp tube body 1.

[0024] As an optimization solution, Figure 3 As shown, a connecting rubber pad 9 is glued and fixed to the outer surface of the cleaning sponge 8, and a fixing groove 10 that cooperates with the connecting rubber pad 9 is opened inside the fixing sleeve 7.
