[0067] See also Figures 1 to 3, this embodiment provides an LED lamp, which includes an optical part 1, an end cover 2, a base 3, a side cover 4, a connecting assembly 5 and a light source part 6. Among them, the optical part 1 is arranged in a long strip shape, and the optical part 1 is covered on the light-emitting side of the light source part 6. The light emitted by the light source part 6 passes through the optical part 1 and is emitted from the LED lamp. A light-emitting cavity 7 is provided on the optical part 1 along its length direction, and both ends of the light-emitting cavity 7 are open. The end cover 2 is connected to the end of the optical part 1; specifically, the end cover 2 is adapted to be snap-fitted with the end of the optical part 1. Further, the LED lamp may include two end covers 2, and the two end covers 2 are adapted to be snap-fitted with the two ends of the optical part 1 respectively. The base 3 is arranged in a long strip shape, and the base 3 is connected to the optical part 1, and the base 3 and the optical part 1 are combined to form a receiving cavity 8. The side cover 4 is connected to the end of the base 3; specifically, the side cover 4 is adapted to be snap-fitted with the end of the base 3. Further, the LED lamp may include two side covers 4, and the two side covers 4 are respectively adapted to be snap-fitted with the two ends of the base 3. The connecting assembly 5 is respectively connected to the optical part 1 and the base 3, so that the optical part 1 and the base 3 are connected and fixed. It can also be said that the optical part 1 and the base 3 are connected as a whole through the connecting assembly 5. The light source part 6 is arranged along the length direction of the optical part 1, and the optical part 1 is covered on the light emitting side of the light source part 6. Further, the light source part 6 can be arranged in the light emitting cavity 7 of the optical part 1.

[0068] It can be understood that by providing a light-emitting cavity 7 in the optical part 1 and arranging the light source part 6 in the light-emitting cavity 7, the distance between the light source part 6 and the top of the optical part 1 can be shortened, thereby reducing the light loss of the LED lamp; and compared with the light source part 6 being arranged on the base 3 or other components, the light source part 6 is directly arranged in the light-emitting cavity 7 of the optical part 1, which can make the positional relationship between the light source part 6 and the optical part 1 more stable, thereby making the angle of the light emitted by the light source part 6 after passing through the optical part 1 more stable. In addition, the accommodating cavity 8 formed by the base 3 and the optical part 1 can be used to place the power supply, power cord, control element and other components of the light source part 6, that is, the power supply, power cord, control element and other components of the light source part 6 can be accommodated in the accommodating cavity 8 formed by the base 3 and the optical part 1, thereby preventing other components of the light source part 6 from blocking the light emitted by the light source part 6, thereby helping to further reduce the light loss of the LED lamp. And relative to the setting mode of the external power supply, the design of arranging the power supply and other components in the accommodating cavity 8 in this embodiment can effectively reduce the height of the entire lamp.

[0069] It is also understandable that the two ends of the optical part 1 are blocked by two end covers 2 that can be matched and snapped with the two ends of the optical part 1. The snapping method can effectively improve the assembly efficiency, thereby making it easier to assemble the LED lamp. In addition, the two ends of the base 3 are blocked by two side covers 4 that can be matched and snapped with the two ends of the base 3, which further facilitates the assembly of the LED lamp.

[0070] Furthermore, the base 3 is made of metal. It is understandable that the metal base 3 has excellent properties such as high strength and high wear resistance, which helps to increase the service life of the LED lamp. It should be noted that the material of the base 3 in this embodiment is preferably aluminum or steel, which is low in cost. Figure 2 , Figure 5 , the connecting component 5 is arranged in the accommodating cavity 8, and the connecting component 5 can be a spring structure. The connecting component 5 can include two first connecting parts 51, and the two first connecting parts 51 are respectively adapted and clamped with the two sides of the optical part 1 along the length direction thereof. The connecting component 5 can also include a second connecting part 52, and the second connecting part 52 is connected and fixed with the base 3. The second connecting part 52 of the connecting component 5 can include one or more openings, and a locking member (such as a screw, a screw, a bolt, etc., not shown in the figure) can pass through the opening of the second connecting part 52 of the connecting component 5, so as to connect and fix the connecting component 5 with the base 3. In addition, because the first connecting part 51 of the connecting component 5 is connected and fixed with the optical part 1, and the second connecting part 52 of the connecting component 5 is connected and fixed with the base 3, the optical part 1 and the base 3 are relatively fixed through the connecting component 5. The first connecting part 51 can further include a hook part 511, and the hook part 511 is arranged at the end of the first connecting part 51. The hook part 511 is connected and fixed with the optical part 1, so that the connecting component 5 is connected with the optical part 1. It should be noted that the connection method between the connecting component 5 and the optical part 1 can be selected according to the actual application scenario. For example, a card slot is formed by bending on the optical part 1, and a card hook is integrally formed on the connecting component 5. The card hook and the card slot are adapted to be connected. It can be understood that the card slot and the card hook are connected in a simple structure, which is convenient for assembly and can reduce the application of fasteners. Specifically, the connecting component 5 is made of bent metal sheets and has a certain elasticity. In this embodiment, the locking member is a screw, and the connecting component 5 is locked and fixed on the base 3 by the screw. In addition, the number of connecting components can be set to multiple to strengthen the connection strength between the base 3 and the optical part 1. In this embodiment, the number of connecting components is two, and the two connecting components 5 are respectively located at the two ends of the LED lamp. It can be understood that through the application of the connecting component, the application of fasteners on the LED lamp can be reduced, thereby reducing the leakage of fasteners, thereby improving the smoothness of the appearance of the LED lamp.

[0071] See also Figures 1 to 5 Preferably, the cross section of the optical portion 1 facing away from the base 3 is arc-shaped, which helps to improve the softness of the light and make the light diverge more evenly, reducing the glare of the light.

[0072] More preferably, the optical part 1 and the end cap 2 are made of the same light-transmitting material. It is understandable that the optical part 1 and the end cap 2 are made of the same light-transmitting material, which can effectively reduce the dark areas of the light at both ends of the LED lamp. In addition, when multiple LED lamps are used end to end, the dark areas of the light at the connection can be effectively reduced. It should be noted that in this embodiment, the material of the optical part 1 and the end cap 2 can be selected from any material in the prior art, such as PC material, and no specific requirements or restrictions are made for this. Preferably, the optical part 1 and the end cap 2 are made of PC material that is milky white and has a haze, so that the light output is softer.

[0073] Furthermore, the optical part 1 is diffusely arranged on both sides along its length direction, that is, the height of the optical part 1 close to the center side of the LED lamp is higher than the height of the optical part 1 away from the center side of the LED lamp. In other words, the height of the optical part 1 decreases from the center position of the LED lamp to both ends of the length, so that the irradiation range of the light is wider and more uniform. In this embodiment, the central angle corresponding to the inclination of the optical part 1 on both sides along its length direction is 5-10°. Preferably, the inclination angle of the optical part 1 on both sides along its length direction is 6° to 10°.

[0074] Further, refer to Figure 3 , 5As shown, the optical part 1 may include a first face part 11. The first face part 11 extends along the length direction of the LED lamp. In the cross section at the height of the LED lamp, the first face part 11 is arc-shaped, that is, the cross section of the first face part 11 is arranged in a circular arc shape. In other words, the cross section of the optical part 1 on the side away from the base 3 is arranged in a circular arc shape. The first face part 11 is arranged on the light-emitting side of the light source part 6 and is covered on the light source part 6. The optical part 1 may include a second face part 12, and the second face part 12 extends along the length direction of the LED lamp. The second face part 12 may be connected to the first face part 11. Furthermore, the second face part 12 may be integrally formed with the first face part 11, thereby reducing the component installation process, reducing the production process, and thus reducing the manufacturing cost. In this embodiment, two second face parts 12 are included, and the two second face parts 12 are respectively arranged at both ends of the first face part 11. The second face portion 12 may have an angle b at the connection with the first face portion 11, 60°≤b≤120°, so that the distance between the first face portion 11 and the light source portion 6 is increased by the setting of the second face portion 12, thereby making the light output of the LED lamp more uniform and soft, and reducing the light spot. The optical portion 1 may include a third face portion 13, and the third face portion 13 extends along the length direction of the LED lamp. The third face portion 13 may be arranged on the opposite side of the first face portion 11. The light source portion 6 may be arranged on the third face portion 13, and further, the light source portion 6 may be arranged between the first face portion 11 and the third face portion 13. The third face portion 13 is connected to the second face portion 12. Further, the third face portion 13 may be integrally formed with the second face portion 12, thereby reducing the component installation process, reducing the production process, and thus reducing the manufacturing cost. The third face portion 13 may include a connecting transition portion 14. The connecting transition portion 14 is connected to the second face portion 12. In other words, the third face portion 13 can be connected to the second face portion 12 through the connecting action of the connecting transition portion 14. The present embodiment includes two connecting transition parts 14, which are respectively arranged at the two ends of the third face part 13, and the two connecting transition parts 14 are respectively connected to the two second face parts 12. The connecting transition part 14 and the part on the third face part 13 where the light source part 6 is installed have an angle c, 90°≤c≤180°; preferably, 100°≤c≤170°; optimally, 120°≤c≤150°. Therefore, the connecting transition part 14 can reflect the light emitted by the light source part 6 while connecting the third face part 13 and the second face part 12, thereby reducing light loss. In the cross section of the height of the LED lamp, the second face part 12 is arranged between the first face part 11 and the third face part 13. The second face part 12 is connected to the first face part 11 and the third face part 13 to form a closed space, namely the light-emitting cavity 7.

[0075] The optical part 1 may include a third connecting part 15, and the third connecting part 15 is arranged on the third face part 13. Further, the third connecting part 15 is arranged on the side of the third face part 13 facing away from the light emitting surface, that is, the third connecting part 15 is arranged on the opposite side of the light source part 6. The third connecting part 15 extends along the length direction of the LED lamp. In the cross section at the height of the LED lamp, the third connecting part 15 may be hook-shaped. In the present embodiment, the third connecting part 15 is arranged at the junction of the connecting transition part 14 and the light source part of the third face part 13, and extends in the direction away from the light source part 6. The end of the third connecting part 15 may have a side extending toward the base 3. The optical part 1 is connected and fixed to the connecting component 5 through the third connecting part 15.

[0076] Furthermore, the light source portion 6 may be an LED light bar. A mounting groove 16 is provided on one side of the light emitting cavity 7 of the optical portion 1 close to the base 3, that is, on the third surface 13 along its length direction, and the LED light bar is embedded in the mounting groove 16, which helps to improve the assembly efficiency of the LED lamp. In addition, because the LED light bar is embedded in the mounting groove 16, the LED light bar can be better limited, which helps to ensure the structural stability of the LED lamp. Specifically, the mounting groove 16 may include two convex ribs 161, and the LED light bar is arranged between the two convex ribs 161, and the two convex ribs 111 play a limiting role on the LED light bar. In this embodiment, an avoidance hole for the power cord and other components of the LED light bar to pass through is provided on the bottom wall of the mounting groove 16, so that the power cord and other components of the LED light bar can be placed in the accommodating cavity 8. It should be noted that in other embodiments, the LED lamp can also be adhered to the side of the light emitting cavity 7 close to the base 3 by glue, and no specific requirements and restrictions are made for this.

[0077] Preferably, the LED light strip includes a light board and a plurality of lamp beads, and the plurality of lamp beads are evenly spaced on the light board along the length direction of the light board. In order to further reduce the dark area of ​​the light at the connection when multiple LED lamps are connected end to end, the distance between the outermost lamp beads of the light board and the edge of the light board is less than the distance between two adjacent lamp beads. Specifically, the ratio of the distance between the outermost lamp beads of the light board and the edge of the light board to the distance between two adjacent lamp beads is 0.25-0.6; preferably 0.25-0.4; and optimally 0.25.

[0078] In order to further improve the uniformity of the light output of the LED lamp, a plurality of mounting grooves 16 may be provided on one side of the light-emitting cavity 7 close to the base 3 (i.e., the third surface 13). The plurality of mounting grooves 16 are evenly spaced on one side of the light-emitting cavity 7 close to the base 3, and in the cross section of the height of the LED lamp, the plurality of mounting grooves 16 are symmetrically arranged with the longitudinal axis in the height direction of the LED lamp as the axis. There are a plurality of LED light bars corresponding to the number of mounting grooves 16. In the present embodiment, the number of mounting grooves 16 is two, and the number of LED light bars is also correspondingly set to two. Of course, in other embodiments, the number of mounting grooves 16 may also be four, six or more, and no specific requirements or restrictions are made for this.

[0079] See also Figures 3 to 5 In order to make the light output angle larger, the light output more uniform and there is no obvious bright area in the center of the LED lamp, there may be an angle between the mounting grooves 16 on both sides, so that after the light source part 6 is installed in the mounting groove 16, there is an angle between the light source parts 6 on both sides. In this embodiment, there is an angle a between the two mounting grooves 16, that is, the angle between the two light source parts 6 is a. The range of angle a is 140° to 175°; preferably, the range of angle a is 150° to 170°; more preferably, angle a is 160°. Thereby, the light emitted by the two light source parts 6 can be emitted toward different sides in the width direction of the LED lamp, respectively, thereby increasing the light output angle. It can be understood that by setting the above-mentioned angle, the light output angle can be increased, that is, the irradiation range of the light can be increased.

[0080] Furthermore, by setting the angle, in the cross section of the height of the LED lamp, the light source part 6 can be at least partially set in the base 3, thereby ensuring the distance from the light source part 6 to the light-emitting surface, and then reducing the height of the optical part 1 exposed from the base 3 while ensuring that there is no obvious light spot on the light-emitting surface. That is, the height of the entire lamp is reduced. Specifically, the ratio of the height D1 of the optical part 1 to the height D2 of the base 3 is D1:D2≤1, preferably D1:D2≤0.8, and the optimal D1:D2≤0.6.

[0081] In order to reduce the cost of enterprises producing LED lamps, the base 3 is diffusely arranged on both sides along its length direction, that is, the width of the base 3 on the side close to the optical part 1 is greater than the width of the base 3 on the side away from the optical part 1, so that several bases 3 can be stacked and stored, thereby reducing the cost of packaging and transportation, that is, it can reduce the cost of enterprises producing LED lamps.

[0082] See also Figure 1Preferably, a through hole 41 is provided on the side cover 4. It is understandable that in the process of assembling the LED lamp, wiring can be performed through the through hole 41 on the side cover 4, which is more convenient for assembly. In addition, the through hole 41 on the side cover 4 can also be used for heat dissipation. When multiple LED lamps need to be connected end to end for application, the through holes 41 on adjacent side covers 4 can be interconnected to ensure better heat dissipation effect. In order to reduce the entry of dust or impurities into the interior of the LED lamp, the through hole 41 on the side cover 4 can be blocked by a cover plate. At the same time, in order to ensure a good heat dissipation effect, a straight-shaped hole can also be opened on the cover plate.
