Technical Field

[0001] The utility model relates to the technical field of chandeliers, and in particular to an LED chandeliers provided with a heat dissipation device. Background Art

[0002] A chandelier is a high-grade decorative lighting fixture that is hung on the indoor ceiling. Large chandeliers are installed on structural layers, such as floor slabs, lower chords of roof trusses and beams, while small chandeliers are often installed on shelves or reinforced joists. Whether it is a single chandelier or a combination of chandeliers, they are all produced by the lighting factory at one time. The difference is that a single chandelier can be installed directly, while a combination of chandeliers must be installed after or during installation. For large-area and strip-shaped lighting, the form of hanging rods suspending light boxes and light stands is often used. The characteristic of a chandelier is that it is eye-catching, so the style of the chandelier directly affects the style of the entire living room.

[0006] As an improvement, the hanging plate is made of heat-conducting material, which facilitates the heat sink to dissipate heat from the bulb body.

[0007] As an improvement, a decorative cover located around the transparent protective cover is fixedly provided on the bottom surface of the hanging plate, and a decorative strip is provided at the bottom end of the decorative cover to improve the aesthetics of the device.

[0008] As an improvement, the decorative cover is evenly provided with heat dissipation holes, and the arrangement of the heat dissipation holes can cooperate in preliminary heat dissipation.

[0009] As an improvement, a group of telescopic rods are hinged symmetrically on the bottom surface of the mounting plate. The other end of the telescopic rod is connected to a clamping plate close to the side wall of the hanging plate. The side wall of the hanging plate is provided with a clamping groove that cooperates with the clamping plate to limit the hanging plate and prevent the hanging chain from shaking left and right and affecting stability.

[0010] Compared with the prior art, the utility model has the following advantages: a mounting groove close to the bulb body is arranged on the hanging plate, a heat sink is placed in the mounting groove, and the heat sink is screwed into the mounting groove through a fixing plate on the heat sink. During the operation of the bulb body, the heat sink promotes heat dissipation, thereby improving the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS
