Problems solved by technology

[0003] However, in order to increase the brightness of this ceiling lamp technical solution, multiple LED chips need to be arranged in the center of the lamp, and the closed lampshade makes the heat generated too concentrated in the cavity of the ceiling lamp, resulting in deterioration of the heat dissipation conditions of the LED.
Moreover, the upper and lower parts of the lamp are separated by the LED substrate, so that the air flow on the upper part of the substrate is not smooth, which further affects the service life of the LED.
[0004] In addition, the existence of the lampshade often causes some phototactic insects or dust to enter and reduce the light transmittance of the lampshade, which affects the lighting effect of the LED ceiling lamp.

Embodiment 1

[0031] see figure 1 and figure 2 , an LED ceiling lamp, comprising a lamp housing 1, an LED lamp group 3 enclosed in the lamp housing 1 and a reflector disposed in the lamp housing 1 and positioned above the LED lamp group 3 2.

[0032] see image 3 , the lamp housing 1 is a rotating body, and its rotating generatrix is ​​a curve protruding outward. The lamp housing 1 is vertically penetrated, and is provided with an upper opening 10 and a lower opening 11 of the housing. Six fixing holes 103 are provided on the edge of the upper opening 10 of the housing. A supporting plate 101 extending toward the center of the lamp housing 1 is provided at the edge of the lower opening 11 of the housing, and a reinforcing rib 102 is provided on the inner surface of the supporting plate 101 to make the lower opening 11 of the housing form a C-shaped opening.

[0033] see Figure 4 and Figure 5 , the LED lamp group 3 includes eight LED modules 30 connected in a ring. The annularly c...

Embodiment 2

[0039] see Figure 9 , Figure 10 and Figure 11 , in this embodiment, in addition to including all the features of Embodiment 1, it also includes a heat dissipation air duct arranged in the handle of the reflector, and the heat dissipation air duct is arranged on the lower end peripheral surface of the handle or on the support plate The ventilation holes on the top make the upper and lower parts of the ceiling lamp communicate, and according to the principle of convection, the air in the upper and lower parts of the LED ceiling lamp can flow, so that the heat dissipation effect of the LED ceiling lamp can be further improved.

Abstract

The invention discloses a light-emitting diode (LED) ceiling lamp which comprises a lamp shell body and an LED light module arranged in the lamp shell body and further comprises a reflective body. The lamp shell body comprises a shell body upper opening and a shell body lower opening, and the LED lamp module is arranged at the edge opening of the shell body lower opening in the shape of a back taper ring. The periphery of the reflective body is closed, and the reflective body is arranged at the upper end opening of the LED lamp module. The LED lamp module is enclosed with a certain upward angle at the outer edge of the reflective body so that light emitted by the LED lamp module is cast on the reflective body and sent out from the shell body lower opening after being reflected for multiple times by the reflective body, and soft top light illumination is provided. Meanwhile, the structure dissipates heat distribution of an LED and enlarges heat dissipation area of the LED lamp module and improves heat dissipation effects of the ceiling lamp. In addition, an external lamp shade is discarded so that the illumination effects of the LED ceiling lamp are not affected due to invasion and harassment of insects or dust.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED ceiling lamp. Background technique [0002] The existing LED ceiling lamps are very dazzling due to the direct radiation of LED light. Therefore, this kind of ceiling lamp is usually also provided with a lampshade for softening the LED light. For example, the Chinese invention patent application with the notification number CN discloses an LED ceiling lamp, which includes a light source, and the light source includes at least one white LED and at least one colored LED. The lighting effect of the LED ceiling lamp is soft and non-glare, and the color rendering is higher. [0003] However, in order to increase the brightness of this ceiling lamp technical solution, it is necessary to arrange a plurality of LED chips in the center of the lamp. The closed lampshade makes the heat generated too concentrated in the cavity of the ceiling lamp, causing the heat dissipation conditions of the ...
