Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp. Background Art

[0002] Existing LED lamps are mostly circular in structure, consisting of a lamp housing, base, and light panel. The lamp housing and base together form a lamp cavity, which is housed within the lamp cavity and connected to the base. The light panel houses the LED chip and control circuit. The lamp housing is made of a translucent material, with smooth inner and outer surfaces, allowing light to diffuse evenly through the housing. Because the smooth inner and outer surfaces of the lamp housing allow light to diffuse evenly through the housing, it fails to focus light on the illuminated surface, resulting in poor lighting effects. Utility Model Content

[0003] The purpose of the utility model is to provide an LED lamp tube to solve the problem of poor lighting effect in existing LED lamp tubes because the inner and outer surfaces of the lamp shell are both smooth planes, light is evenly diffused around the lamp shell, and the light cannot be concentrated to the illuminated surface.

[0004] The utility model is realized through the following technical solutions:

[0005] An LED lamp tube includes a lamp housing, a base and a lamp board. The lamp housing and the base together form a lamp cavity. The lamp board is accommodated in the lamp cavity and connected to the base. The lamp housing forms an inner cohesive arc surface on the inner surface of the lamp board, and the lamp housing forms an outer cohesive arc surface on the outer surface of the lamp board. The spacing between the inner cohesive arc surface and the outer cohesive arc surface gradually decreases from the middle to both sides. The lamp housing is formed with a plurality of top cohesive teeth on the inner cohesive arc surface, and the plurality of top cohesive teeth are arranged circumferentially of the lamp housing.

[0006] Furthermore, the outer surface of the lamp housing is composed of a plurality of planes sequentially connected in the circumferential direction thereof, and any two adjacent planes are arranged at an angle.

[0007] Furthermore, the angle between two adjacent planes ranges from 160° to 170°.

[0008] Furthermore, the inner surface of the lamp housing is formed with a plurality of side-converging teeth on opposite sides of the inner-converging arc surface, and the plurality of side-converging teeth are arranged in a circumferential direction of the lamp housing.

[0009] Furthermore, each of the side-converging teeth is inclined toward the inner-converging arc surface.

[0010] Furthermore, the height of the side-convex teeth protruding from the inner surface of the lamp housing is higher than the height of the top-convex teeth protruding from the inner surface of the lamp housing.

[0011] Furthermore, the inner cohesive arc surface is a symmetrical arc surface, and the plurality of top-converging teeth are symmetrically arranged about the symmetry axis of the inner cohesive arc surface.

[0012] Furthermore, a plurality of the side-converging teeth located on opposite sides of the inner cohesive arc surface are symmetrically arranged with respect to the symmetry axis of the inner cohesive arc surface.

[0013] Furthermore, the top-converging teeth extend toward the inner center of the lamp housing.

[0014] Furthermore, the radius of the inner cohesive arc surface is greater than the radius of the outer cohesive arc surface, and the center of the inner cohesive arc surface and the center of the outer cohesive arc surface are located on the same side.

[0015] The advantage of this technical solution lies in that, by configuring an inner cohesive curved surface on the inner surface of the lamp housing facing the lamp board, and an outer cohesive curved surface on the outer surface of the lamp housing facing the lamp board, the distance between the inner cohesive curved surface and the outer cohesive curved surface gradually decreases from the center to the sides. As a result, the lens portion of the lamp housing formed with the inner cohesive curved surface and the outer cohesive curved surface can converge light onto the illuminated surface, thereby achieving high light energy utilization and excellent lighting effects. In addition, because the lamp housing has a plurality of top converging teeth arranged circumferentially on the inner cohesive curved surface, part of the light converged on the inner cohesive curved surface is reflected / scattered in other directions, making the light output from the lens portion uniform.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Figure 1-4 As shown, the LED lamp tube includes a lamp housing 1, a base 2 and a lamp board 3. The lamp housing 1 and the base 2 together form a lamp cavity 4. The lamp board 3 is accommodated in the lamp cavity 4 and connected to the base 2. The lamp board 3 is encapsulated with an LED chip (not marked in the figure) and a control circuit (not marked in the figure). The inner surface of the lamp housing 1 faces the lamp board 3 to form an inner cohesive arc surface 101, and the outer surface of the lamp housing 1 faces the lamp board 3 to form an outer cohesive arc surface 102. Both the inner cohesive arc surface 101 and the outer cohesive arc surface 102 are arched outward, and the distance between the inner cohesive arc surface 101 and the outer cohesive arc surface 102 gradually decreases from the middle to both sides. The lamp housing 1 has a plurality of top cohesive teeth 103 formed on the inner cohesive arc surface 101, and the plurality of top cohesive teeth 103 are arranged circumferentially of the lamp housing 1. Specifically, the radius of the inner cohesive arc surface 101 is greater than the radius of the outer cohesive arc surface 102, and the center of the inner cohesive arc surface 101 and the center of the outer cohesive arc surface 102 are located on the same side. The portion of the lamp housing 1 where the inner cohesive arc surface 101 and the outer cohesive arc surface 102 are formed is defined as a lens portion 104. This embodiment provides an LED lamp tube to address the problem of poor lighting effects in existing LED lamp tubes, where the inner and outer surfaces of the lamp housing are both smooth planes, causing light to diffuse evenly in all directions through the lamp housing and failing to focus the light on the illuminated surface. This is primarily achieved by configuring the inner cohesive arc surface 101 on the inner surface of the lamp housing 1 facing the lamp board 3, and configuring the outer cohesive arc surface 102 on the outer surface of the lamp housing 1 facing the lamp board 3. The spacing between the inner cohesive arc surface 101 and the outer cohesive arc surface 102 gradually decreases from the middle to the sides, thereby enabling the lens portion 104 of the lamp housing 1 where the inner cohesive arc surface 101 and the outer cohesive arc surface 102 are formed to focus light on the illuminated surface, thereby achieving high light energy utilization and excellent lighting effects. Furthermore, since the lamp housing 1 has a plurality of top-converging teeth 103 arranged circumferentially on the inner converging arc surface 101 , the light converged on the inner converging arc surface 101 is partially reflected / scattered in other directions, so that the lens portion 104 emits light uniformly.

[0024] In this embodiment of the present invention, the outer surface of the lamp housing 1 is composed of a plurality of planes 105 sequentially connected along its circumference, with any two adjacent planes 105 forming an angle. This arrangement, by configuring the outer surface of the lamp housing 1 to be composed of a plurality of planes 105 sequentially connected along its circumference and arranged at an angle, provides the lamp housing 1 with a good focusing effect and uniform light output.

[0025] In the embodiment of the present invention, the angle β between two adjacent planes 105 ranges from 160° to 170°.

[0026] In this embodiment of the present invention, the inner surface of the lamp housing 1 is formed with a plurality of side-convex teeth 106 on opposite sides of the inner cohesive arc surface 101. These side-convex teeth 106 are arranged circumferentially around the lamp housing 1 and are configured to reflect or scatter light toward the inner cohesive arc surface 101. By disposing the side-convex teeth 106 on opposite sides of the inner cohesive arc surface 101, the light emitted from the opposite sides of the inner cohesive arc surface 101 is partially reflected or scattered toward the inner cohesive arc surface 101, allowing the lens portion 104 to focus more light, resulting in a better lighting effect.

[0027] In the embodiment of the present invention, each side focusing tooth 106 is inclined toward the inner cohesive arc surface 101. By configuring the side focusing teeth 106 to be inclined toward the inner cohesive arc surface 101, the side focusing teeth 106 can reflect / scatter more light toward the inner cohesive arc surface 101, allowing the lens portion 104 to focus more light, thereby improving the lighting effect.

[0028] In the embodiment of the present invention, the height at which the side focusing teeth 106 protrude from the inner surface of the lamp housing 1 is higher than the height at which the top focusing teeth 103 protrude from the inner surface of the lamp housing 1. By configuring the height at which the side focusing teeth 106 protrude from the inner surface of the lamp housing 1 to be higher than the height at which the top focusing teeth 103 protrude from the inner surface of the lamp housing 1, the side focusing teeth 106 can reflect or scatter more light toward the inwardly converging arc surface 101, allowing the lens portion 104 to focus more light, thereby achieving a better lighting effect.

[0029] In the embodiment of the present invention, the cohesive arc surface 101 is a symmetrical arc surface, and the plurality of top-converging teeth 103 are symmetrically arranged about the symmetry axis of the cohesive arc surface 101. By configuring the cohesive arc surface 101 as a symmetrical arc surface and configuring the plurality of top-converging teeth 103 to be symmetrically arranged about the symmetry axis of the cohesive arc surface 101, the plurality of top-converging teeth 103 are rationally distributed, and the reflection / scattering effect is excellent.

[0030] In the embodiment of the present invention, the top-converging teeth 103 extend toward the inner center of the lamp housing 1. By configuring the top-converging teeth 103 to extend toward the inner center of the lamp housing 1, the top-converging teeth 103 are reasonably distributed, resulting in a good reflection / scattering effect.

[0031] In the embodiment of the present invention, the side-gathering teeth 106 located on opposite sides of the inner cohesive arc surface 101 are symmetrically arranged about the symmetry axis of the inner cohesive arc surface 101. By arranging the side-gathering teeth 106 located on opposite sides of the inner cohesive arc surface 101 symmetrically about the symmetry axis of the inner cohesive arc surface 101, the side-gathering teeth 106 are rationally distributed, achieving a good reflection / scattering effect.
