Problems solved by technology

Although this patent can realize the angle adjustment of the lamp within the range of 360 degrees, the rotating structure of the lamp in this patent is realized through the cooperation between the spherical lamp cap and the fixing seat. A hole that can accommodate the ball head is reserved in the fixing seat, which makes the overall volume of the lamp cannot be made small, and is not suitable for use in occasions where the installation space is small

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1 to Figure 8 As shown, it is a specific embodiment of the present invention. The lamp includes a lamp cap 1, a lamp holder 2 and a rotating shaft 3, wherein the lamp cap 1 and the lamp holder 2 are connected through the rotating shaft 3, and the lamp cap 1 is rotatably accommodated in the lamp holder 2 within.

[0024] The lamp cap 1 of the present embodiment adopts LED light source illumination, and the lamp cap 1 comprises lampshade 11, lens 12, circuit board 13 and heat dissipation plate 14, and lens 12, circuit board 13 and heat dissipation plate 14 are all accommodated in lampshade 11 after being assembled; The board 13 is provided with an LED chip, the lens 12 is fixedly arranged on one side of the circuit board 13 and opposite to the LED chip, and the heat dissipation plate 14 is fixedly arranged on the other si...

Abstract

The invention discloses a lamp with a rotatable lamp cap. The lamp comprises lamp holders and a lamp cap, and is characterized in that: the lamp cap is connected with each lamp holder through a rotating shaft; the rotating shaft comprises four shaft heads which are distributed in a cross shape; each shaft head is provided with annular grooves formed along the circumferential direction of the shaft head; each annular groove is provided with a fastener capable of rotating relative to the corresponding shaft head; two opposite fasteners positioned on a first straight line of the cross shape of the rotating shaft are fixedly connected to the bottom of the lamp cap; and two opposite fasteners positioned on another straight line of the cross shape of the rotating shaft are fixedly connected to opposite lamp holders at the bottom of the lamp cap. The rotation of the lamp cap relative to the lamp holders is realized by adopting the cross-shaped rotating shaft, so that the lamp cap can be adjusted optionally in a 360-degree range relative to the lamp holders, the rotation adjusting range of the lamp cap is expanded, the illumination direction is more flexible, and a power supply lead can be effectively prevented from being knotted due to the rotation of the lamp cap; and moreover, the structure is more compact and the size of the lamp is greatly reduced.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp with a rotatable lamp head. Background technique [0002] In order to realize the flexible adjustment of the lighting orientation and improve the scope of application and flexibility of use of the lamps, the lamp holders of many existing lamps are designed to be rotatable structures. [0003] For example, the Chinese utility model patent "Adjustable Angle LED Spotlight" with the patent number ZL200820201330.7 discloses an adjustable angle LED spotlight with continuously adjustable LED light output angle and uniform illuminance, but the installation structure of the spotlight in this patent It is relatively complicated. The adjustment of the illumination angle is realized through the angle adjustment plate, which cannot realize the continuous adjustment of the illumination angle of the LED lamp, which makes the angle adjustment of the LED lamp not flexible enough. [0004] In addition, for a lamp...
