Detailed Description

To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Several embodiments of the utility model are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a combined LED lamp according to a first embodiment of the present invention is shown, including a plurality of electrically connected LED lamp units, where each LED lamp unit includes a circuit board 110 and an LED lamp bead 120 disposed on the circuit board 110, a lens 130 is disposed on the LED lamp bead 120, and the type of the lens 130 can be adaptively adjusted to be a refractive type or a reflective type according to actual requirements;

a heat dissipation plate 140 is arranged on one side of the circuit board 110, which faces away from the lens 130, a heat dissipation cavity 141 corresponding to the LED lamp bead 120 is formed in the heat dissipation plate 140 in a hollow manner, a plurality of heat dissipation holes 142 are formed in the inner wall of the heat dissipation cavity 141 and are communicated with the outside, and a dust screen (not shown) is covered at the heat dissipation holes 142 and is used for preventing external dust from entering the heat dissipation cavity 141 and reducing the heat dissipation effect;

the opposite ends of the circuit board 110 are respectively provided with an electronic wire 150, and the plurality of LED lamp units are electrically connected through the electronic wires 150.

Specifically, a plurality of the LED lamp units are connected in series with each other through the electronic wire 150, and the LED lamp beads 120 continuously emit light after being powered on by an external power supply of the electronic wire 150.

An accommodating slot 143 is formed on an upper surface of the heat dissipating plate 140 facing the circuit board 110, and the shape of the accommodating slot 143 fits the outer contour of the circuit board 110. In the present embodiment, the circuit board 110 has a rectangular shape, but is not limited thereto, and may have a circular shape, a square shape, a polygonal shape, or a circular shape. The purpose of the accommodating slot 143 being attached to the outer contour of the circuit board 110 is to limit the mounting position of the circuit board 110 on the heat dissipation plate 140, so that the LED lamp beads 120 arranged on the circuit board 110 can be accurately aligned with the heat dissipation cavity 141, thereby ensuring the heat dissipation effect.
