Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.

[0035] The inventors of the present invention have found through research that after using the LED tower chandelier currently used for a period of time, the illumination effect will decrease, the illumination area will be diffused, and the light will be uneven. On the heat pipe radiator of the chandelier, the light source component is heated for a long time, which causes the bulging deformation of the light-emitting plane. The inventor further researched and found that the bulging deformation of the light source component will reduce the contact area between it and the heat pipe radiator, thereby affecting the heat transfer of the light source component, causing overheating damage to ...

Abstract

The invention discloses an LED tower crane lamp. The LED tower crane lamp comprises a heat pipe radiator, a lampshade, a light source assembly, drive power sources and a reflection cup. The light source assembly comprises a PCB and LED lamp beads fixed to the PCB. The heat pipe radiator comprises a heat pipe heat absorbing part, a base plate matched with the heat pipe heat absorbing part, a heat pipe cooling part connected with the heat pipe heat absorbing part, and cooling fins arranged at the heat pipe cooling part, the lampshade is fixed to the base plate, and the reflection cup is arranged in the lampshade and fixed to the base plate. The LED tower crane lamp further comprises buckles. Each buckle comprises a fixing part and a buckling part, wherein the buckle is fixed to the base plate through the fixing part. The PCB is clamped between the buckling parts and the base plate. The distance between the fixing parts and the center of the reflection cup is D1, the distance between the outer edge of the PCB and the center of the reflection cup is D2, and the distance between the buckling parts and the center of the reflection cup is D3, wherein D1 is larger than D2, and D2 is larger than D3. The LED tower crane lamp has a very good heat dissipation effect.

Description

technical field [0001] The invention relates to an LED tower pendant light. Background technique [0002] LED tower chandeliers are more and more applied to the construction industry because of their safety, reliability, high brightness, energy saving, and long life. The LED tower chandelier is installed on the top of the tower crane, which can provide reliable lighting for the construction site. The currently used LED tower chandeliers will experience a decrease in lighting effect after a period of use, diffuse lighting areas, and uneven light. Contents of the invention [0003] In order to at least solve the above-mentioned technical problems existing in the prior art, the present invention provides an LED tower chandelier with better heat dissipation efficiency and lighting effect at least. [0004] The technical solutions provided by the present invention at least relate to: [0005] As one aspect of the present invention, it relates to a LED tower pendant light, in...
