[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0032] Reference Figures 1 to 12As shown, the adjustable light LED lamp provided by the embodiment comprises a lamp shell 10, a lampshade 40, a light source driving board 20 and a light source 30, the light source driving board 20 is provided with a light adjusting module 21, the light adjusting module 21 is provided with a knob 211 for light adjusting switching, and the light source driving board 20 is drivingly connected with the light source 30. Specifically, in the embodiment, the light source 30 is an LED filament lamp light source, and the light adjusting module 21 is a structure for adjusting color temperature, brightness or color in the prior art, that is, the light adjusting operation of the light adjusting module 21 is realized by rotating the knob 211, and the light adjusting module 21 and the light source driving board 20 provided with the light adjusting module 21 are both in the prior art, which will not be described in detail herein.
[0033] The lamp shell 10 comprises a fixed bottom shell 11, a limiting ring 12 and a rotating ring 13, the rotating ring 13 is rotatably assembled on the fixed bottom shell 11 and extends inwardly to have an abutting step 131, the limiting ring 12 is mounted on the inner side of the rotating ring 13 and abuts against the abutting step 131, the inner side wall of the limiting ring 12 and the inner side wall of the fixed bottom shell 11 are both provided with a clamping groove, specifically, the clamping groove provided on the inner side wall of the limiting ring 12 is defined as a first clamping groove 121, and the clamping groove provided on the inner side wall of the fixed bottom shell 11 is defined as a second clamping groove 111. The light source driving board 20 is inserted into the first clamping groove 121 of the limiting ring 12 and the second clamping groove 111 of the fixed bottom shell 11 and is fixedly connected with the fixed bottom shell 11, so that the fixed assembly of the light source driving board 20, the limiting ring 12 and the fixed bottom shell 11 is realized, and the rotating ring 13 is also stably limited. The knob 211 of the light adjusting module 21 is matched with the rotating ring 13 to realize the rotating switching of the rotating ring 13, and finally realize the light adjusting operation.
[0034] By adopting the above structure, no fixing member (such as a bolt) is needed for assembly and fixation, the assembly is simple, and the assembly efficiency is greatly improved.
[0035] Further, the first clamping groove 121 of the limiting ring 12 is provided with an arched first convex cover 122, the light source driving board 20 is provided with a first notch 22, and the first convex cover 122 of the limiting ring 12 is matched with the first notch 22 of the light source driving board 20 to realize the axial limiting; in this way, the axial and circumferential limiting of the light source driving board 20 and the limiting ring 12 is realized.
[0036] Specifically, the second clamping groove 111 of the fixed bottom shell 11 is provided with an arched second convex cover 112, the light source driving board 20 is provided with a second notch 23, and the second convex cover 112 of the fixed bottom shell 11 is matched with the second notch 23 of the light source driving board 20; in this way, the axial and circumferential limiting of the fixed bottom shell 11 and the light source driving board 20 is realized.
[0037] Thus, the stable installation of the limiting ring 12, the fixed bottom shell 11 and the light source driving board 20 can be realized. When assembling, the rotating ring 13 is first placed on the fixed bottom shell 11, and then the limiting ring 12 is placed, so that the limiting ring 12 abuts against the abutting step 131 of the rotating ring 13. Then, the position of the limiting ring 12 is adjusted, so that the first clamping groove 121 of the limiting ring 12 corresponds to the second clamping groove 111 of the fixed bottom shell, that is, the first clamping groove 121 and the second clamping groove 111 are located in the same vertical plane. Then, the light source driving board 20 is inserted into the first clamping groove 121 and the second clamping groove 111 in alignment. When inserted in place, the first notch 22 of the light source driving board 20 cooperates with the first protruding boss 122, and the second notch 23 of the light source driving board 20 cooperates with the second protruding boss 112 of the fixed bottom shell 11, thereby realizing stable installation. The cooperation of the notch and the protruding boss is simple in structure, firm and effective in limiting.
[0038] Of course, in other embodiments, the fixed cooperation of the notch and the protruding boss can also be replaced by other structures. For example, the cooperation mode of the first notch 22 and the first protruding boss 122 can be replaced by the following mode: the top of the limiting ring 12 further forms a clamping hole 124 penetrating to the outer peripheral surface, and the light source driving board 20 is inserted into the clamping hole 124 of the limiting ring 12 to press against the limiting ring 12. In this way, the limiting ring 12 can also be fixed.
[0039] In the embodiment, the outer peripheral bottom of the limiting ring 12 is provided with a first step portion 126, and the inner side wall of the fixed bottom shell 11 is provided with a second step portion 113. The first step portion 126 of the limiting ring 12 cooperates with the second step portion 113 of the fixed bottom shell 11 to realize positioning, so as to ensure the concentricity of the limiting ring 12 and the fixed bottom shell 11, and the assembly precision is better.
[0040] The inner side wall of the rotating ring 13 is provided with two spaced apart blocking walls 132, and the knob 211 of the dimming module 21 cooperates between the two blocking walls 132. In this way, when the rotating ring 13 rotates, the knob 211 of the dimming module 21 is driven to move by the two blocking walls 132, thereby realizing dimming operation. The structure is simple, and the two blocking walls 132 are not directly connected with the knob 211, so as not to be stuck. Of course, in other embodiments, the cooperation mode of the rotating ring 13 and the knob 211 of the dimming module 21 is not limited to this.
[0041] Further, the limiting ring 12 forms a limiting window 123, and the two blocking walls 132 of the rotating ring 13 are located in the limiting window 123, and further move within the range of the limiting window 123, so as to prevent the rotating ring 13 from rotating excessively and damaging the dimming module 21.
[0042] The bottom surface of the rotating ring 13 in contact with the fixed bottom shell 11 is formed with a plurality of first arc-shaped protrusions 133 distributed at intervals, and in this embodiment, the first arc-shaped protrusions 133 cover the bottom surface of the rotating ring 13. The first arc-shaped protrusions 133 are arranged to form a line contact between the rotating ring 13 and the fixed bottom shell 11, effectively reducing the frictional force of the contact.
[0043] Similarly, the bottom surface of the limiting ring 12 in contact with the abutting step 131 of the rotating ring 13 is formed with a plurality of second arc-shaped protrusions 125 distributed at intervals; the limiting ring 12 contacts the abutting step 131 of the rotating ring 13 through the second arc-shaped protrusions 125, which can also effectively reduce the frictional force, so that the rotating ring 13 is more smooth when rotated, improving the hand feeling.
[0044] Further, the lamp holder 50 is fixed on the fixed bottom shell 11 and electrically connected to the light source driving board 20; specifically, the lamp holder 50 can adopt a standard size lamp holder structure in the prior art, such as E14, E26 and E27.
[0045] Further, the lamp shade 40 is fixed on the rotating ring 13 and rotates with the rotating ring 13, and of course, in other embodiments, the lamp shade 40 can also be fixed on the fixed bottom shell 11 or the limiting ring 12. At the same time, the shape of the lamp shade 40 can also be a circular arc, thereby forming a bulb lamp, etc.
[0046] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all of them are within the protection scope of the utility model.
