By rotating the lampshade body on the lampshade base, the lampshade body is obliquely arranged at a certain angle relative to the lamp holder, light of a light source in the lamp holder can be reflected and irradiated to the corresponding position through the lampshade body, namely, the frustum-shaped lampshade body changes the direction of the light, the irradiation direction of the spotlight is adjusted, and adjusting operation is convenient; a moving groove is formed in the upper end of the lampshade base in the rotating direction of the lampshade body, and a moving block matched with the moving groove is arranged at the lower end of the lampshade base. The lampshade base can move along the moving groove through the moving block, so that the lampshade body moves relative to a light source in the lamp holder. Even if the cover body moves backwards relative to the light source, light emitted by the light source can be reflected by the cover body and then directly irradiates outwards, so that light loss is reduced, and a better light control effect is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, and more particularly, to an adjustable spotlight. Background Art

[0002] Spotlights are a typical modern lighting style with no main light and no fixed scale. They can create an indoor lighting atmosphere. If a row of small spotlights are combined, the light can change into wonderful patterns. Spotlights have soft light and are elegant. They can also provide local lighting to enhance the atmosphere, so they are widely used.

[0003] Many existing spotlights cannot adjust the irradiation direction. After being installed and fixed, they can only irradiate in a fixed direction. When the irradiation position needs to be adjusted, the spotlight needs to be disassembled and reinstalled, which cannot meet the needs of users and brings trouble to users. Utility Model Content

[0025] Refer to the attached Figures 1 to 7 The adjustable spotlight of the utility model is described in further detail.

[0026] An adjustable spotlight includes a lamp holder 1 with a built-in light source 11 and a lampshade assembly 2, wherein the light source 11 can be an object that emits light, such as an LED lamp. The lampshade assembly 2 includes a lampshade base 21 and a cover body 22 rotatably disposed above the lampshade base 21, and the cover body 22 is in the shape of a frustum.

[0027] By rotating the cover 22 on the lampshade base 21 so that the cover 22 is tilted at a certain angle relative to the lamp holder 1, the light from the light source 11 in the lamp holder 1 is reflected by the cover 22 and irradiated to the corresponding position. That is, the frustum-shaped cover 22 has a light redirecting effect, thereby adjusting the illumination direction of the spotlight. There is no need to disassemble the spotlight to adjust the illumination direction, and the adjustment operation is convenient.

[0028] The upper end of the lampshade base 21 is provided with a movable groove 12 along the rotation direction of the cover body 22, and the lower end of the lampshade base 21 is provided with a movable block 211 adapted to the movable groove 12; the lampshade base 21 can be moved along the movable groove 12 by the movable block 211, so that the cover body 22 is displaced relative to the light source 11 in the lamp holder 1; even if the cover body 22 moves backward relative to the light source 11, the light emitted by the light source 11 can be reflected by the cover body 22 and directly irradiated outward, avoiding multiple refractions of the light in the cover body 22, thereby reducing light loss and having a better light control effect.

[0029] The moving block 211 is tightly fitted with the moving groove 12, but when the relative position of the cover body 22 and the lamp holder 1 needs to be adjusted, it is only necessary to push the lampshade assembly 2 with force to move the moving block 211 along the moving groove 12; after the adjustment is completed, the moving block 211 is tightly fitted with the moving groove 12, positioning the lampshade assembly 2, and locking the lampshade assembly 2 in the corresponding position to prevent the lampshade assembly 2 from moving on its own, thereby having better stability performance.

[0030] The cover body 22 is rotatably arranged on the lampshade base 21 through the inner shell 23, and the inner shell 23 is provided with an avoidance notch 233 to prevent interference between the inner shell 23 and the lamp holder 1 when the cover body 22 is driven to rotate; an arc-shaped limiting groove 231 is provided on the side wall of the inner shell 23, and the arc of the arc-shaped limiting groove 231 is 30 degrees; a plurality of positioning holes 232 are provided in the arc-shaped limiting groove 231; a positioning bead 213 adapted to the positioning hole 232 is provided on the lampshade base 21, and the positioning bead 213 cooperates with the positioning hole 232 to lock the cover body 22 in the corresponding position, thereby preventing the cover body 22 from rotating by itself after the rotation is completed, and improving the structural stability; the arc-shaped limiting groove 231 cooperates with the positioning bead 213, so that the cover body 22 can rotate 30 degrees relative to the lampshade base 21, that is, the cover body 22 rotates within a range of 30 degrees.

[0031] The lamp holder 1 is provided with a waist-shaped hole 13 arranged in the same direction as the movable groove 12, and the lamp shade base 21 is provided with a connecting hole 212 arranged opposite to the waist-shaped hole 13. The fastening screw 3 passes through the waist-shaped hole 13 and cooperates with the connecting hole 212 to connect the cover body 22 assembly to the lamp holder 1. At the same time, when the lamp shade base 21 moves relative to the lamp holder 1, the fastening screw 3 used to connect the cover body 22 assembly moves along the waist-shaped hole 13. The above description is only a preferred embodiment of the present utility model.

[0032] The scope of protection of the present invention is not limited to the above-mentioned embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
