Embodiment 1

[0026] Embodiment one, see image 3 , a LED chandelier with a wide lighting angle, comprising a top cover 1 , a bracket 2 and a lampshade 3 .

[0027] The top cover 1 is an upwardly arched shell-like structure. The top cover 1 is circular. The top cover 1 is formed by sheet metal stamping with an aluminum plate. The surface of the top cover 1 is provided with a sprayed black surface layer. The beneficial effect of setting the black surface layer is that the top cover can absorb the heat generated by the invention in time and dissipate it to the air in the peripheral space.

[0028] The top cover 1 is provided with cooling holes 11 . The cooling holes 11 are elongated holes extending straight up and down along the surface of the top cover. The existence of heat dissipation holes is designed in such a way that the damage to the strength of the top cover is small.

[0029]The top of the top cover 1 is provided with a suspension rod 12 . The suspension rod 12 is located at ...

Embodiment 2

[0052] Embodiment two, see Figure 4 , for ease of viewing of the graph, in this figure as well as Figure 5 Only the two second heat sinks 4 located on the left and right sides of the bracket 2 are drawn, and the rest of the second heat sinks are not drawn.

[0053] The difference with embodiment one is:

[0054] The lower end of the top cover 1 is provided with a connecting groove 16 opening downward. The connecting groove 16 is located on the outer peripheral edge of the first connecting edge 13 .

[0055] The lampshade 3 is cylindrical.

[0056] The upper end of the lampshade 3 is an open end, and the upper end of the lampshade 3 is screwed into the connecting groove 16 .

[0057] The upper end of the lampshade 3 is provided with a tapered section 35 with a large opening at the upper end and a smaller opening at the lower end.

[0058] A step 36 is provided between the inner surface of the lower end of the lampshade 3 and the tapered section 35 , and a reflective laye...

Abstract

The invention relates to an LED lamp, in particular to an LED ceiling lamp with a wide illuminating angle, which comprises a power supply, a lampshade, a top cover and a support connected below the top cover. The support is of a big-end-up prismatic table structure, a first LED lamp panel with the front facing down is arranged on the lower end face of the support, a second LED lamp panel with the front inclined downwards is arranged on a side of the support, and the power supply is used for driving the first LED lamp panel and the second LED lamp panel. The LED ceiling lamp with the wide illuminating angle is large in illuminating angle and high in light utilization rate, and solves the problem of small effective illuminating area caused by small illuminating range of an existing LED ceiling lamp. Besides, the illuminating range of the LED ceiling lamp with the wide illuminating angle can be adjusted, so that the problem of poor adaptability to the illuminating area caused by non-adjustability of the illuminating range of the existing LED ceiling lamp.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED pendant lamp. Background technique [0002] Due to the advantages of small size, low power consumption, long service life, high brightness, environmental protection and durability, LEDs are widely used in lamps. [0003] Wherein the LED chandelier comprises a face-down LED light board and a lampshade covered on the LED light board. When in use, hang the chandelier in the space that needs to be illuminated by hanging wires, chains or rods. The front side refers to the luminous side of the lamp. [0004] In the Chinese Patent Authorization Publication No. CN201187717Y, a patent document titled "LED Chandelier" discloses an LED chandelier, which includes a conical lampshade (top cover), a power supply and an LED module (LED lamp board), a power supply and The LED module is installed on the mounting plate, and the mounting plate is installed at the lower end of the lampshade. The mounting pla...
