ANGLE-ADJUSTED LAMP

Abstract

An angle-adjustable lamp comprises a lamp body, a plurality of heat sinks, a plurality of connecting rods, and a plurality of light-transmitting covers. The plurality of heat sinks are rotatably connected to a side wall of the lamp body respectively through the plurality of connecting rods. The plurality of heat sinks are rotationally symmetrically disposed around a longitudinal center axis of the lamp body. Each of the plurality of light-transmitting covers is disposed on a side of a corresponding one of the plurality of heat sinks facing away from the lamp body. When the plurality of heat sinks are rotated around the plurality of connecting rods, an angle between each of the plurality of light-transmitting covers and the lamp body is correspondingly changed, so that a light exit angle of light transmitted through each of the plurality of light-transmitting covers is correspondingly changed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present disclosure will be further described below in combination with the accompanying drawings and embodiments.

Embodiment 1

[0022] Referring to FIGS. 1 to 4, an angle-adjustable lamp is illustrated and comprises a lamp body 4, a plurality of heat sinks 3, a plurality of connecting rods 2, and a plurality of light-transmitting covers 7.

[0023] The plurality of heat sinks 3 are rotatably connected to a side wall of the lamp body 4 respectively through the plurality of connecting rods 2, and the plurality of heat sinks 3 are rotationally symmetrically disposed around a longitudinal center axis of the lamp body 4.

[0024] Each of the plurality of light-transmitting covers 7 is disposed on a side of a corresponding one of the plurality of heat sinks 3 facing away from the lamp body 4. When the plurality of heat sinks 3 are rotated around the plurality of connecting rods 2, an angle between each of the plurality of light-transmitting covers 7 and the lamp body 4 is changed correspondingly, so that a light exit angle of light transmitted through each of the plurality of light-transmitting covers 7 is also changed correspondingly.

[0025] In order to achieve a rotating connection between the lamp body 4 and each of the plurality of heat sinks 3, positions of the side wall of the lamp body 4 respectively corresponding to the plurality of heat sinks 3 are respectively disposed with two lugs 8, and a side of each of the plurality of heat sinks 3 facing the lamp body 4 has a connecting member 9. The two lugs 8 and the connecting member 9 respectively comprise a position-providing hole. Each of the plurality of connecting rods 2 passes through the position-providing holes of the two lugs 8 and the connecting member 9 and is connected to a plug 1.

[0026] In this embodiment, a surface of each of the plurality of heat sinks 3 comprises a grid-shaped heat dissipation hole.

[0027] In this embodiment, the plurality of heat sinks 3 are three heat sinks 3. The three heat sinks 3 are sector-shaped. An inner edge of each of the three heat sinks 3 comprises a position-providing arc 33, and the three heat sinks 3 are spaced from each other in a circumferential direction of the lamp body 4 to facilitate a rotation of the three heat sinks 3.

[0028] Each of the plurality of heat sinks 3 is integrally formed with a mounting groove 31. A light-emitting diode (LED) light source board 32 and a corresponding one of the plurality of light-transmitting covers 7 are sequentially assembled in the mounting groove 31, and the mounting groove 31, the LED light source board 32, and the corresponding one of the plurality of light-transmitting covers 7 are fixed together through screws 6. For ease of installation, a positioning block 311 is disposed on an edge of the mounting groove 31, and a positioning groove 321 is defined on the LED light source board 32. Each of four corners of each of the plurality of light-transmitting covers 7 is disposed with a positioning column 71.

[0029] In this embodiment, the three heat sinks 3 can be rotated to different positions relative to the lamp body 4 to form a planar light source (see FIG. 3), an elevation light source (see FIG. 2), or a multi-faceted light source (see FIG. 4).

[0030] The angle-adjustable lamp of the present disclosure can be freely adjusted by rotating the plurality of heat sinks 3 for places that require more light irradiation at other angles, thereby changing angles between the plurality of light-transmitting covers 7 and the lamp body 4. For example, in the exhibition hall, some places require more light to murals on a wall, and some places only need more light to enable passage of visitors, which can be achieved by adjusting the angle of the angle-adjustable lamp. In this way, under the premise of 360° light output, the free adjustment of the key lighting area can be realized.

Embodiment 2

[0031] Referring to FIG. 5, the difference between an angle-adjustable lamp in Embodiment 2 and the angle-adjustable lamp in Embodiment 1 is described below. In this embodiment, the plurality of heat sinks 3 is two heat sinks 3, which are disposed rotationally symmetrically around the longitudinal center axis of the lamp body 4.

Embodiment 3

[0032] Referring to FIG. 6, the difference between an angle-adjustable lamp in Embodiment 3 and the angle-adjustable lamp in Embodiment 1 is described below. In this embodiment, the plurality of heat sinks 3 are four heat sinks 3, which are disposed rotationally symmetrically around the longitudinal center axis of the lamp body 4.

[0033] The plurality of heat sinks 3 of the angle-adjustable lamp of the present disclosure can be two, three, four, or five heat sinks 3. A lamp holder 5 may be a screw-on type or a snap-on type.

[0034] The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
