Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a lighting fixture provided in an embodiment of the present application, and fig. 2 is a second structural schematic diagram of the lighting fixture provided in the embodiment of the present application. The lighting fixture 10 may include a lamp cover 11, a lamp strip 12, and a power cord 13. The power line 13 is electrically connected to the lamp strip 12, and the lamp strip 12 is disposed on the lamp cover 11.

The lamp cover 11 may form an outer contour of the lighting fixture 10. Meanwhile, the lamp cover 11 can serve as a protective shell of the internal circuit structure of the lighting lamp 10 and the lamp strip 12, and the internal circuit structure of the lighting lamp 10 and the lamp strip 12 are prevented from being damaged due to collision or falling of the lighting lamp 10. The lamp cover 11 may include only the bottom surface, and the lamp cover 11 has a plate-shaped structure. It is understood that the bottom surface of the lamp cover 11 may not be a flat structure but may be formed in an arch structure similar to a vegetable greenhouse. The lamp cover 11 may also include a bottom surface and a side surface, the side surface is disposed around the periphery of the bottom surface and perpendicular to the bottom surface, and the lamp cover 11 has a groove-like structure. It will be appreciated that the side surfaces may also be arranged obliquely to the bottom surface rather than perpendicularly thereto. The bottom surface of the lamp cover 11 may be rectangular or rounded rectangular, the bottom surface of the lamp cover 11 may also be circular or elliptical, and the bottom surface of the lamp cover 11 may also be shaped like a playground track with two sides being straight lines and two ends being semi-circles. The embodiment of the present application does not limit the specific shape of the lamp cover 11.

The lamp cover 11 may be made of a material with good thermal conductivity, for example, the lamp cover 11 may be made of aluminum or an aluminum alloy. When the lamp area 12 that sets up on lamp lid 11 is luminous and produce the heat, because the good heat conductivility of lamp lid 11, the produced heat in lamp area 12 can be conducted for lamp lid 11, and then gives off the external world with the heat by lamp lid 11 to produce too high heat when avoiding lamp area 12 to give out light and lead to lamp area 12 temperature to rise and influence life. It is understood that the lamp cover 11 may also be made of other materials with good thermal conductivity, for example, the lamp cover 11 may also be made of copper or copper alloy, and the lamp cover 11 may also be made of iron or iron alloy. The embodiment of the present application does not limit the specific material of the lamp cover 11.

The light strip 12 serves as a light emitting component of the lighting fixture 10, and the light strip 12 may include one to more LED lights. For example, the light strip 12 may include a large LED bulb, and the light strip 12 may also include a plurality of small LED beads. The lamp strip 12 is disposed on the lamp cover 11, and heat generated when the lamp strip 12 emits light is emitted to the outside through the lamp cover 11. Specifically, the lamp strip 12 can be adhered to the lamp cover 11 through glue, the lamp strip 12 can also be screwed on the lamp cover 11 through screws, and the lamp strip 12 can also be clamped on the lamp cover 11 through buckles. It will be appreciated that the light strip 12 may also be provided on the light cover 11 by a combination of a plurality of connection means. The embodiment of the present application does not limit the specific manner in which the lamp strip 12 is disposed on the lamp cover 11.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a lamp cover of an illumination lamp according to an embodiment of the present disclosure.

It will be appreciated that, compared to the entire lamp cover 11 being made of copper or copper alloy, the production cost of the lamp cover 11 can be significantly saved by making only the first portion 111 of the lamp cover 11 contacting the light strip 12 of copper or copper alloy and making the second portion 112 of the lamp cover 11 not contacting the light strip 12 of aluminum or aluminum alloy or plastic material with poorer thermal conductivity and lower cost. Of course, in the case of not considering the production cost, the heat dissipation effect of the lamp cover 11 will be better if the lamp cover 11 is made of copper or copper alloy material or even silver material.

In some embodiments, the side surface of the light strip 12 and/or the abutting surface of the light strip 12 and the light cover 11 are further coated with a heat conductive material for assisting in dissipating heat generated when the light strip 12 emits light. For example, the heat-conducting silicone grease can be coated on the binding surface of the lamp strip 12 and the lamp cover 11 and the side surface of the lamp strip 12, and the heat-conducting silicone grease can assist in dissipating heat generated when a part of the lamp strip 12 emits light.
