The two side plates 102 are oppositely arranged on both sides of the bottom plate 101, and the side plates 102 are inclined relative to the bottom plate 101; the number of lamp boards 200 is two, and the two lamp boards 200 are respectively arranged on the two side plates 102, and the light emitted by the lamp boards 200 directly irradiates on the lamp cover 300; the lamp cover 300 is arranged on the lamp housing 100, the lamp cover 300 is semi-elliptical, and the lamp cover 300 is located directly above the bottom plate 101. It should be noted that the lamp housing 100 also includes two arc-shaped plates 103, and the two arc-shaped plates 103 are respectively connected to the two side plates 102. The bottom plate 101 can support the side plates 102 and is used to connect to the wall so that the lamp housing 100 is installed on the wall. The side plates 102 are used to provide an installation base for the lamp boards 200 and are used to enable the lamp boards 200 to be inclined to improve the light emission uniformity of the lighting fixture. The arc-shaped plates 103 can also support the side plates 102, improve the overall structural strength of the lamp housing 100, and also play a protective role.

[0035] It should be added that this lighting fixture also includes a plugging component. The plugging component is arranged at both ends of the lamp housing 100 and is used to plug the openings at both ends of the lamp housing 100. The plugging component includes a plugging bottom shell 400 and a plugging cover 401. The plugging bottom shell 400 is connected to the lamp housing 100, the plugging cover 401 is connected to the plugging bottom shell 400, and the end of the lamp cover 300 extends into the plugging component.

[0036] The lighting fixture provided by the present utility model sets the lamp board 200 on the inclined side plate 102, so that the light emitted by the lamp board 200 can irradiate on the lamp cover 300 more evenly, thereby improving the softness of the light of this lighting fixture. Moreover, the lamp cover 300 is semi-elliptical, and the two lamp boards 200 are oppositely arranged, so that the light emitted by the lamp boards 200 irradiates on the lamp cover 300 more fully, improving the light utilization rate of the lamp boards 200, and thus achieving the effect of energy conservation and emission reduction.

[0037] Please refer to Figure 4 , in a possible implementation manner, the acute angle formed between the side plate 102 and the bottom plate 101 is greater than 15° and less than 60°. It is easy to understand that when the inclination angle of the lamp board 200 is between 15° and 60°, the light emitted by the lamp board 200 can irradiate on the lamp cover 300 more fully, which is more conducive to improving the light emission uniformity and light utilization rate of the lighting fixture. Specifically, in this embodiment, the acute angle formed between the lamp board 200 and the bottom plate 101 is 36°.

[0038] Please refer to Figure 4, in a possible implementation, the side plate 102 is provided with a limiting portion 104. The number of the limiting portions 104 is two, and the two limiting portions 104 are respectively arranged on both sides of the side plate 102. The lamp board 200 is arranged between the two limiting portions 104. It is easy to understand that when the lamp board 200 is placed on the side plate 102, the arrangement of the limiting portion 104 can limit the lamp board 200, avoid the lamp board 200 from sliding on the side plate 102, which is beneficial to improving the stability of the lamp board 200. Moreover, a plurality of lamp beads are arranged in an array on the lamp board 200. When the lamp board 200 needs to be maintained, the user can directly take the lamp board 200 from the side plate 102, which provides great convenience for the user's maintenance work.

[0039] Please refer to Figure 4 , in a possible implementation, the limiting portion 104 is L-shaped. It is easy to understand that the L-shaped limiting portion 104 can further limit the lamp board 200, so that the lamp board 200 can only be pulled out from the length direction of the side plate 102, avoid the lamp board 200 from detaching from the side plate 102 when the lamp shakes, and further improve the stability of the lamp board 200. And the L-shaped limiting portion 104 does not block the light-emitting side of the lamp board 200 and does not affect the light emitted by the lamp beads.

[0040] Please refer to Figure 5 , in a possible implementation, an LED driving power supply 500 is further arranged in the lamp housing 100. The LED driving power supply 500 is electrically connected to the lamp board 200. It is easy to understand that the LED driving power supply 500 is arranged on the plug bottom shell 400, the LED driving power supply 500 is electrically connected to the circuit board 600. The LED driving power supply 500 is a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Moreover, an elastic buckle 402 is further arranged on the plug bottom shell 400, and the elastic buckle 402 is clamped with the LED driving power supply 500, so that the LED driving power supply 500 is fixed on the plug bottom shell 400.

[0041] Please refer to Figure 3 , in a possible implementation, a circuit board 600 is further arranged in the lamp housing 100. The circuit board 600 is electrically connected to the lamp board 200. A first gear switch 601 is arranged on the circuit board 600. The first gear switch 601 is used to adjust the color temperature of the lamp board 200. It should be noted that the circuit board 600 is fixedly arranged on the plug bottom shell 400. The user only needs to slide the first gear switch 601 to adjust the color temperature of the lamp board 200. Specifically, the color temperature range that the first gear switch 601 can adjust is 2700 - 6500K. That is to say, this lamp can achieve any color in the color temperature range of 2700 - 6500K, which greatly improves the user experience.

[0042] Please refer to Figure 3, in a possible implementation, it is characterized in that a second gear switch 602 is further provided on the circuit board 600, and the second gear switch 602 is used to adjust the power of the lamp board 200. It should be noted that the user only needs to slide the second gear switch 602 to adjust the color temperature of the lamp board 200, thereby changing the illumination intensity of the lamp. Specifically, the power of the lamp board 200 is divided into 1% - 100%, with 1% being the minimum power and 100% being the maximum power. The user can achieve any illumination intensity within the range of 1% - 100% power by sliding the second gear switch 602, enabling the user to adjust a comfortable illumination intensity and greatly improving the user experience.

[0043] In a possible implementation, both the first gear switch 601 and the second gear switch 602 have four gears. It should be noted that for the convenience of user adjustment and cost reduction, the gears of the first gear switch 601 and the second gear switch 602 can also be divided in this lamp, so that both the first gear switch 601 and the second gear switch 602 have four adjustable gears. Among them, the four adjustable gears of the first gear switch 601 are the color temperatures of 3000K, 4000K, 5000K, and 6500K respectively, and the four adjustable gears of the second gear switch 602 are the powers of 40%, 60%, 80%, and 100% respectively.

[0044] Please refer to Figure 3 , in a possible implementation, a plurality of stripes are provided on the inner side wall of the lamp shade 300. It should be noted that the stripes extend along the length direction of the lamp shade 300, and the plurality of stripes are arranged at equal intervals. The setting of the stripes can scatter the light, which is beneficial to further improving the uniformity of the light emitted by the lamp, and thus improving the user experience.

[0045] Please refer to Figure 2 and Figure 3 , in a possible implementation, the lamp shade 300 is slidably arranged relative to the lamp housing 100. It should be noted that the lamp shade 300 is slidably connected to the lamp housing 100, and there is a space in the plug assembly for the lamp shade 300 to slide, so that the lamp shade 300 can slide into the plug assembly. When the user needs to toggle the first gear switch 601 or the second gear switch 602, they only need to slide the lamp shade 300 towards one end of the lamp housing 100, and the first gear switch 601 and the second gear switch 602 will be exposed, thus facilitating user adjustment.

[0046] The above-mentioned implementation is only the preferred implementation of the present utility model, and it cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the protection scope required by the present utility model.
