[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-7 As shown, a high-light-efficiency LED lamp tube includes a lamp tube 1, an LED light source board 2 arranged in the lamp tube 1, and a lamp holder 3 arranged at both ends of the lamp tube 1 and electrically connected to the LED light source board 2. The inner wall of the lamp tube 1 is provided with a first clip 11, a second clip 12, a third clip 13 and a fourth clip 14 distributed in a trapezoidal shape along its cross section; the first clip 11 and the second clip 12, the second clip 12 and the third clip 13, the third clip 13 and the fourth clip 14, and the fourth clip 14 and the first clip 11 can all be used to install the LED light source board 2.

[0031] A high-light-efficiency LED lamp tube in an embodiment of the present application includes a lamp tube, an LED light source board and a lamp holder. The inner wall of the lamp tube is provided with a first clip seat, a second clip seat, a third clip seat and a fourth clip seat distributed in a trapezoidal shape. The LED light source boards can be installed respectively through adjacent clip seats. The present application can adapt to the installation of LED light source boards of different widths and sizes, thereby increasing the applicability of the LED lamp tube. When multiple LED light source boards are installed in the lamp tube, multi-angle light emission can be achieved, thereby improving the light emission efficiency. The structure is simple and has good application prospects.

[0032] like Figure 2As shown in the example of embodiment 1 of the present application, a first clamping groove 101 is formed between the first clamping seat 11 and the second clamping seat 12 ; in embodiment 1 of the present application, a narrow LED light source board can be installed in the first clamping groove 101 .

[0033] like Figure 3 As shown in the example of embodiment 2 of the present application, a second clamping groove 103 is formed between the third clamping seat 13 and the fourth clamping seat 14 ; in embodiment 2 of the present application, a wider LED light source board can be installed in the second clamping groove 103 .

[0034] In a specific embodiment of the present application, the width of the first snap-fitting slot 101 is smaller than the width of the second snap-fitting slot 103 and they are arranged parallel to each other. The snap-fitting slots of different widths can be used to adapt to LED light source boards of different widths, thereby improving the applicability of the LED lamp tube.

[0035] Furthermore, the first clamping slot 101 and the second clamping slot 103 can be used to insert LED light source boards 2 of different widths. Of course, as a further preferred embodiment, Figure 4 As shown in the example of Example 3 of the present application, the first snap-fitting slot 101 and the second snap-fitting slot 103 can be used to respectively install LED light source boards to achieve multi-faceted light emission and improve light emission efficiency.

[0036] Furthermore, if Figure 2 As shown, the light emitting angle of the LED light source board 2 inserted into the first clamping slot 101 is 60°, which makes the light more concentrated and the brightness higher.

[0037] like Figure 5 As shown in the example of Example 4 of the present application, a third clamping slot 102 is formed between the second clamping seat 12 and the third clamping seat 13; a fourth clamping slot 104 is formed between the fourth clamping seat 14 and the first clamping seat 11; the width of the third clamping slot 102 is the same as the width of the fourth clamping slot 104, and they are arranged obliquely to each other. Furthermore, the LED light source board 2 is inserted into the third clamping slot 102 and the fourth clamping slot 104. In Example 3 of the present application, double-sided light emission can be achieved to improve light emission efficiency.

[0038] like Figure 6 As shown in the example of Example 5 of the present application, LED light source boards are inserted into the first snap-fitting slot 101 , the second snap-fitting slot 103 , the third snap-fitting slot 102 and the fourth snap-fitting slot 104 . This design can realize four-sided light emission and further improve the light emission efficiency.

[0039] Furthermore, the lamp tube 1 is made of PC material, and the first clamping seat 11, the second clamping seat 12, the third clamping seat 13 and the fourth clamping seat 14 are all integrated with the lamp tube 1 at the bottom and protruded on both sides in a "Y-shaped" structure, which is convenient for processing and production.

[0040] As a further preferred embodiment, the inner wall of the lamp tube 1 is located between the first clamping seat 11 and the second clamping seat 12, between the second clamping seat 12 and the third clamping seat 13, between the third clamping seat 13 and the fourth clamping seat 14, and / or between the fourth clamping seat 14 and the first clamping seat 11, and has a refractive protrusion 105 protruding toward the middle. The light source can produce a light refraction effect through the regularly concave and convex inner wall, so that the LED light refracted into the surrounding space becomes uniform and soft, and also increases the brightness.

[0041] Furthermore, the LED light source board 2 includes an aluminum substrate 21 and a light source group 22 provided on the aluminum substrate 21. The aluminum substrate 21 can be inserted into the corresponding snap-in slot. This application can meet the installation requirements of aluminum substrates 21 of various widths and sizes. When multiple LED light source boards 2 are installed together, multi-faceted light emission can be achieved, further improving the light emission efficiency.

[0042] Further, if Figure 7 As shown, the lamp holder 3 includes a plastic head 31 that is sleeved onto the end of the lamp tube 1, and a driving power supply 32 disposed within the plastic head 31 and electrically connected to the LED light source board 2. The lamp holder 3 is connected to an external AC power supply, which is connected to the driving power supply, converting the AC power into low-voltage DC power, which is then supplied to the LED light source board 2 to cause it to emit light.

[0043] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
