[0035] Reference Figure 2 , Figure 3 , Figure 5 The first light-emitting unit 20 is in the shape of a long strip. The first light-emitting unit 20 can be an LED lamp board with LED lamp beads. The first light-emitting unit 20 is arranged on the first surface 12 of the lamp body 1. The first light-emitting unit 20 is preferably arranged in the middle position of the first surface 12 of the lamp body 1.

Of course, the first light-emitting unit 20 can also be arranged on the first surface 12 of the lamp body 1 by other fixing methods or a combination of multiple methods. In this embodiment, a first clamping groove 181 is provided on the first surface 12 of the lamp body 1. The first light-emitting unit 20 is fixed to the first surface 12 of the lamp body 1 by clamping in the first clamping groove 181. This facilitates the installation of the first light-emitting unit 20, improves the efficiency of personnel installation, and does not require other fixing parts, which not only reduces the manufacturing cost of the LED lamp 100, but also makes the overall appearance structure of the LED lamp 100 simple and beautiful.

[0036] In other embodiments of the present invention, a first mounting hole (not shown) may also be provided on the first surface 12 of the lamp body 1, and the first light-emitting unit 20 may be fixed to the first surface 12 of the lamp body 1 through the first mounting hole. This can further enhance the stability of the first light-emitting unit 20 on the first surface 12 of the lamp body 1 and prevent the first light-emitting unit 20 from loosening or even falling off during use.

[0037] Reference Figure 3 to Figure 5 , the first light-transmitting lampshade 30 is arranged on the light-emitting side of the first light-emitting unit 20 to allow the light emitted by the first light-emitting unit 20 to pass through. The first light-transmitting lampshade 30 can be configured with one or more functions of reflection, refraction, and light transmission to make the light emission of the LED lamp 100 uniform. The first light-transmitting lampshade 30 can also prevent the first light-emitting unit 20 from being damaged or foreign matter from being attached to it, thereby affecting the light-emitting effect of the first light-emitting unit 20. The first light-transmitting lampshade 30 may include a first light-transmitting area 301, a second light-transmitting area 302, and a third light-transmitting area 303. The first light-transmitting area 301 and the third light-transmitting area 303 are preferably symmetrically arranged or approximately symmetrically arranged with respect to the second light-transmitting area 302. In the cross section at the height after the LED lamp is installed to the installation surface, the LED lamp beads of the first light-emitting unit 20 are approximately located directly below the second light-transmitting area 302, that is, in the cross section at the height of the LED lamp, the center line of the second light-transmitting area 302 coincides or approximately coincides with the center line of the LED lamp beads of the first light-emitting unit 20. The light emitted by the first light-emitting unit 20 is irradiated onto the installation surface of the LED lamp 100 through the first light-transmitting area 301, the second light-transmitting area 302 and the third light-transmitting area 303. The first light-transmitting lampshade 30 is in the shape of an elongated strip, and a second slot 182 is provided on the first surface 12 of the lamp body 1.

Specifically, the first light-transmitting area 301 and the third light-transmitting area 303 can have an extension on one side away from the second light-transmitting area 302, and the extension of the first light-transmitting area 301 and the extension of the third light-transmitting area 303 are respectively snapped into the second slot 182, so that the lampshade 30 is connected and fixed to the lamp body 1. And because there are two places for clamping, the stability of the connection between the lampshade 30 and the lamp body 1 can be ensured. The first light-transmitting lampshade 30 can be made of a light-transmitting material such as PC. The first light-transmitting lampshade 30 is preferably milky white and can have a haze, so that the light emitted by the first light-emitting unit 20 is softer. The first light-transmitting lampshade 30 can also be transparent, so as to reduce the light loss of the emitted light.

By setting the thickness of different areas of the first light-transmitting lampshade 30 to be different, the brightness and angle of the light emitted by the first light-emitting unit 20 when passing through the first light-transmitting lampshade 30 can be adjusted, so that the light is more uniform, and the light spot irradiated on the installation surface becomes uniform. Specifically, the vertical distance from the top of the second light-transmitting area 302 to the top of the first light-transmitting area 301 or the third light-transmitting area 303 is D1, and the vertical distance from the top of the first light-transmitting area 301 or the third light-transmitting area 303 to the bottom of the first light-transmitting area 301 is D2, and the range of D1:D2 is 1.15 to 1.45; preferably, the range of D1:D2 is 1.2 to 1.4; more preferably, the range of D1:D2 is 1.25 to 1.35.

[0039] The width of the second light-transmitting area 302 can also be changed to adjust the brightness and angle of the light emitted by the first light-emitting unit 20 when passing through the first light-transmitting lampshade 30, so that the light is more uniform and the light spot irradiated on the mounting surface becomes uniform. Specifically, the width of the second light-transmitting area 302 is D3, and the total width of the first light-transmitting area 301, the second light-transmitting area 302 and the third light-transmitting area 303 is D4, and the range of D3:D4 is 0.1 to 0.8; preferably, the range of D3:D4 is 0.2 to 0.65; more preferably, the range of D3:D4 is 0.3 to 0.5.

The second side panel 51 is arranged on the light emitting side of the third light emitting unit 22. The second side panel 51 can reflect the light emitted by the third light emitting unit 22 to change the light emitting direction so that the light emitted from the third light emitting unit 22 is emitted toward the side away from the mounting surface, thereby improving the light emitting effect of the third light emitting unit 22.

[0049] In order to make the light output angle larger, the light output more uniform, and there is no obvious dark area in the center of the LED lamp 100, the second light-emitting unit 21 and the third light-emitting unit 22 can form an angle a, which is the same or substantially the same as the angle d formed by the first side surface 14 of the lamp body 1 and the second side surface 15 of the lamp body 1. The angle a formed by the second light-emitting unit 21 and the third light-emitting unit 22 is in the range of 90° to 150°; preferably, the angle a is in the range of 100° to 140°; more preferably, the angle a is 120°. In this way, the light emitted by the second light-emitting unit 21 and the third light-emitting unit 22 is emitted toward different sides in the width direction of the LED lamp 100.

[0050] The first side plate 50 and the second side plate 51 are arc-shaped as a whole, and the first side plate 50 and the second side plate 51 have an arc-shaped concave surface 52, and the concave surface 52 faces the direction away from the mounting surface where the LED lamp 100 is installed. The light emitted by the second light-emitting unit 21 and the third light-emitting unit 22 can be diffusely reflected through the arc-shaped first side plate 50 and the second side plate 51, so that the light emitted by the second light-emitting unit 21 and the third light-emitting unit 22 is more uniform and soft, which improves the comfort of the user. Specifically, one side of the first side plate 50 is connected to the lamp body 1, and the other side of the first side plate 50 is a free end 53, and an angle c is formed between the side of the first side plate 50 connected to the lamp body 1 and the free end 53 of the first side plate 50. One side of the second side plate 51 is connected to the lamp body 1, and the other side of the second side plate 51 is a free end 53, and an angle c is also formed between the side of the second side plate 51 connected to the lamp body 1 and the free end 53 of the second side plate 51. The angle c ranges from 80° to 100°; preferably, the angle c ranges from 85° to 95°; more preferably, the angle c is 90°.

[0051] The vertical distance from the top of the first side panel 50 and the second side panel 51 to the free end 53 is D5, and the vertical distance from the free end 53 of the first side panel 50 and the second side panel 51 to the bottom of the LED lamp 100 is D6, and the range of D5:D6 is 1.2 to 2.8; preferably, the range of D5:D6 is 1.5 to 2.5; more preferably, the range of D5:D6 is 1.8 to 2.2. By changing the size of the first side panel 50 and the second side panel 51, the diffuse reflection effect of the first side panel 50 and the second side panel 51 is improved, so that the light emitted by the second light-emitting unit 21 and the third light-emitting unit 22 is more uniform and soft, which improves the comfort of users.

[0052] The material of the first side plate 50 and the second side plate 51 can be metal or other materials with good reflective effect. The metal material has good reflective effect and can improve the light emitting effect of the second light emitting unit 21 and the third light emitting unit 22. The concave surface 52 of the first side plate 50 and the second side plate 51 can also be coated with reflective paint, such as white paint, which further improves the light emitting effect of the second light emitting unit 21 and the third light emitting unit 22.

[0053] The lamp body 1 is also provided with a seventh card slot 187 and an eighth card slot 188. The seventh card slot 187 is close to the connection between the first side surface 14 of the lamp body 1 and the third side surface 16 of the lamp body 1, and the eighth card slot 188 is close to the connection between the second side surface 15 of the lamp body 1 and the fourth side surface 17 of the lamp body 1. The first side plate 50 is clamped in the seventh card slot 187, and the second side plate 51 is clamped in the eighth card slot 188. This facilitates the installation of the first side plate 50 and the second side plate 51, improves the efficiency of installation by personnel, and does not require other fixing parts, which not only reduces the manufacturing cost of the LED lamp 100, but also makes the overall appearance structure of the LED lamp 100 simple and beautiful.

[0054] A first clip 501 is provided on the first side panel 50, a second clip 502 is provided on the second side panel 51, and a ninth clip slot 189 and a tenth clip slot 190 are also provided on the lamp body 1.
