DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] The lampshade of the existing LED light grid lamp is usually formed by connecting two left and right shells. When the lampshade rotates relative to the universal frame, the force exerted by the universal frame on the lampshade easily causes the two shells of the lampshade to deform at the edges due to uneven force, thereby affecting the sealing performance of the lampshade.

[0030] To solve the above technical problems, this embodiment provides an LED grid lamp, please refer to Figures 1 to 3 As shown, Figure 1 This is a three-dimensional diagram of the LED grid lamp in the embodiment. Figure 2 This is an exploded view of the LED grid lamp in the embodiment. Figure 3 This is a side view of the LED grid lamp in the embodiment. Figure 4 for Figure 3 The cross-sectional view of section A in the figure. Figure 5 for Figure 3 Cross-sectional view of section B.

[0031] The LED grid lamp of the present embodiment includes: a lampshade body 1 , a lower cover 2 , an upper cover 3 and a universal frame 4 .

[0032] The lampshade body 1 is used to install the LED lamp assembly, and comprises a first end 11 and a second end 12 facing oppositely. The first end 11 is provided with at least two first insertion holes 13 , and the second end 12 is provided with at least two second insertion holes 14 .

[0033] The lampshade body 1 may be made of aluminum, wherein the first end 11 and the second end 12 are used to connect the lower cover 2 and the upper cover 3 respectively, and the first plug hole 13 and the second plug hole 14 may be provided in two.

[0034] The lower cover 2 is fixedly connected to the first end portion 11 , and includes a first expansion shaft 21 inserted into the first insertion hole 13 . The first expansion shaft 21 is interference-fitted with the inner side of the first insertion hole 13 .

[0035] The lower cover 2 can be fixedly connected to the lampshade body 1 by screw connection or snap connection, and the first expansion axis 21 can be integrally formed with the lower cover 2. The interference fit ensures that there is no gap between the first expansion axis 21 and the lampshade body 1 at the connection, and the deformation space is small.

[0036] The upper cover 3 is fixedly connected to the second end portion 12 , and includes a second expansion shaft 31 inserted into the second insertion hole 14 . The second expansion shaft 31 is interference-fitted with the inner side of the second insertion hole 14 .

[0037] The upper cover 3 can be fixedly connected to the lampshade body 1 by screw connection or snap connection, and the second expansion axis 31 can be integrally formed with the lower cover 2. The interference fit ensures that there is no gap between the second expansion axis 31 and the lampshade body 1 at the connection, and the deformation space is small.

[0038] The gimbal 4 is connected to the lower cover 2 .

[0039] The gimbal 4 is used to adjust the use angle, and an existing gimbal 4 can be used.

[0040] The first expansion axis 21 and the second expansion axis 31 are arranged in pairs, and the paired first expansion axis 21 and the second expansion axis 31 are located on the same axis; the first expansion axis 21 and the second expansion axis 31 are symmetrically arranged on both sides of the universal mount 4 .

[0041] In the LED grid lamp of the above technical solution, when the gimbal 4 rotates, the force of the gimbal 4 is transmitted to the lower cover 2. Since the lower cover 2 and the lampshade body 1 are interference fit through the first expansion axis 21, the force of the lower cover 2 can be transmitted to the lampshade body 1 through the first expansion axis 21, thereby reducing the force transmitted to the edge of the lampshade body 1, reducing the deformation of the lampshade body 1 and the lower cover 2 at the edge, and thus reducing the gap at the edge; at the same time, the upper cover 3 is interference fit with the lampshade body 1 through the second expansion axis 31, and the first expansion axis 21 and the second expansion axis 31 are arranged in pairs, and the first expansion axis 21 and the second expansion axis 31 are symmetrically arranged on both sides of the gimbal 4. In this way, the forces on the upper and lower ends and the left and right sides of the lampshade body 1 tend to be symmetrical, and the overall force is more uniform, avoiding concentration on the local edge of the lampshade body 1, thereby reducing the gap at the edge of the lampshade body 1. It can be seen that the LED grid lamp of this embodiment can effectively reduce the gap at the edge of the lampshade body 1 generated when the universal bracket 4 rotates, thereby improving the sealing performance of the lampshade body 1.

[0042] See also Figure 4 As shown, in order to facilitate the insertion of the first expansion axis 21 and the second expansion axis 31 into the first socket 13 and the second socket 14, the first expansion axis 21 and the second expansion axis 31 include a plug-in joint portion, and the outer diameter of the plug-in joint portion gradually decreases in the direction toward the lampshade body 1. It can be understood that the aperture of the first socket 13 and the second socket 14 can be gradually reduced along its own extension direction, thereby further facilitating the plug-in operation.

[0043] See also Figure 4 As shown, the first jack 13 and the second jack 14 are also arranged in pairs, and the paired first jack 13 and the second jack 14 are connected to each other.

[0044] See also Figure 2 and Figure 5 As shown, in this embodiment, the cross-sectional shape of the first hole 13 and the second hole 14 is the same, and the cross-sectional size gradually decreases from the middle of the lampshade body 1 to the outside; the cross-sectional shape of the first expansion axis 21 and the second expansion axis 31 is the same as the first hole 13 and the second hole 14. Such an arrangement can adapt to the situation where the force of the universal mount 4 is transmitted from the middle of the lampshade body 1 to both sides and decreases, so that the lampshade body 1 is more tightly connected with the upper and lower covers 2.

[0045] See also Figure 2 and Figure 4As shown, in one embodiment of the connection between the gimbal 4 and the upper cover 3, the gimbal 4 includes a limiting portion 41 and a threaded portion 42, and the outer diameter of the threaded portion 42 is smaller than the outer diameter of the limiting portion 41; the lower cover 2 is provided with a stepped hole 22, the stepped hole 22 is located between the first jacks 13, and extends from the outer side of the lower cover 2 to the side close to the lampshade body 1; the limiting portion 41 contacts and is limited at the bottom of the stepped hole 22, the threaded portion 42 passes through the bottom of the stepped hole 22, and is fixed to the inner side of the lower cover 2 by a nut 43.

[0046] See also Figure 4 As shown, further, the upper cover 3 is provided with a protrusion 32 opposite to the position of the universal mount 4; the lampshade body 1 is provided with a third socket 15 arranged toward the protrusion 32 and the nut 43, the protrusion 32 and the nut 43 are located in the third socket 15, and can be interference fit with the third socket 15, so as to balance the forces at both ends of the lampshade body 1.

[0047] See also Figure 1 and Figure 2 As shown, in one embodiment of the above-mentioned LED lamp assembly, the LED lamp assembly includes an LED lamp 5, a lens 6 and a cover 7. The LED lamp 5 is arranged on the lampshade body 1 by bonding or screw connection, the lens 6 is covered on the periphery of the LED lamp 5, and the cover 7 is connected to the lampshade body 1 by buckles or screws. The cover 7 is provided with a limiting hole 70, and the lens 6 is clamped through the limiting hole to fix the lens 6 relative to the lampshade body 1.
