Embodiment 1

[0023] Such as Figure 1 to Figure 5 As shown, an LED lamp includes a lamp cup 1 , a reflective bowl 2 , a heat sink 3 , a heat spreader 4 , an LED light-emitting component 5 , and a light-transmitting cover 7 . The heat spreader includes a heat conduction column 13 and a bottom plate 14 . The cross-section of the heat conducting column 13 is hexagonal. The bottom plate 14 is in the shape of a circular plate. The heat conduction column 13 is arranged at the center of the bottom plate 14 and is perpendicular to the bottom plate 14 . The heat conduction column 13 is arranged at the center of the reflective bowl 2 . The heat dissipation plate 3 is in the shape of a circular plate. The bottom plate 14 is fixedly connected to the cooling plate 3 through the fixing screws 9 . The heat dissipation plate 3 is fixed on the lamp cup 1 . Both the heat spreader 4 and the cooling plate 3 are made of aluminum.

[0024] The LED light emitting part 5 includes a mounting cylinder. The ...

Abstract

The invention discloses an LED lamp, which comprises a lamp cup, a reflective bowl, an LED light-emitting part, and a heat conductor, a heat dissipation plate, and a light-transmitting cover. The center of the reflective bowl; the LED light-emitting component includes a mounting tube, which is sleeved on the heat-conducting column, and several LED lamp beads are arranged on the outer side of the mounting tube in the circumferential direction; the light-transmitting cover is set outside the LED light-emitting component. In the present invention, the LED lamp beads are arranged in the circumferential direction on the outside of the installation tube, and the light emitted by the LED lamp beads can be directly projected onto the reflective bowl, and then projected outward after being reflected by the reflective bowl. Compared with the traditional LED lamp, this In the invention, light does not pass through the light guide column, so the loss of luminous flux is small and the luminous efficiency is high.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp. Background technique [0002] At present, the common LED lights usually include a lamp cup, a reflective bowl, LED light-emitting components, and a light guide column. The light guide column is located in the center of the reflective bowl, and the LED light-emitting component is arranged at one end of the light guide column. The light is injected into the light guide column, the light is projected onto the reflective bowl after being diffused by the light guide column, and the light is projected out through the reflection of the reflective bowl. The disadvantage of the LED lamp is that when the light generated by the LED light-emitting component passes through the light guide column, part of the light is absorbed by the light guide column, resulting in a large loss of luminous flux and low light efficiency. [0003] For example: Chinese Patent Publication No. CN103...
