[0046] Example
[0047] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, this embodiment provides a light bulb with adjustable color temperature, including a housing 10 , a lampshade 11 , a light source board 12 , an adjustment switch 13 and a toggle switch 14 .
[0048] Specifically, the lampshade 11 can be set at one end of the shell 10 by snapping, bonding or threaded connection to accommodate the light source board 12 in the shell 10. The side of the light source board 12 facing the lampshade 11 is the light-emitting surface, and the light-emitting surface is provided with lamp beads 122 of different colors, while the side of the light source board 12 away from the lampshade 11 is the backlight surface. In addition, an adjustment switch 13 is also provided on the light-emitting surface of the light source board 12. The adjustment switch 13 has an adjustment handle 131 for switching gears. The light source board 12 has multiple circuits. When the adjustment handle 131 is turned so that it is in different positions, different circuits are connected to adjust the brightness of lamp beads 122 of different colors, thereby realizing color temperature adjustment.
[0049] The toggle switch 14 includes a paddle 141 and a lever 142, one end of the lever 142 is set on the paddle 141, and a clearance opening 121 is set on the light source panel 12, the adjustment switch 13 is set close to the clearance opening 121, and the adjustment handle 131 of the adjustment switch 13 is protruded toward the clearance opening 121, so that the position of the adjustment handle 131 is placed above the clearance opening 121, so that the other end of the lever 142 can pass through the clearance opening 121 and be connected to the adjustment handle 131, and the paddle 141 is slidably set on the outer wall of the shell 10 for user adjustment. Steering the paddle 141 to make it slide relative to the shell 10 can drive the lever 142 to toggle the adjustment handle 131, thereby achieving color temperature adjustment, and the operation is simple and convenient.
[0050] Furthermore, to prevent the lever 142 from blocking the light-emitting surface of the light source panel 12, the present embodiment utilizes a structural design in which the toggle switch 14 and the adjustment switch 13 are disposed on opposite sides. The paddle 141 is located on the backlight side of the light source panel 12, and the lever 142 passes through the clearance opening 121 to connect to the adjustment handle 131. This ensures that the light-emitting surface of the light source panel 12 is not blocked, thus ensuring a good lighting effect. Furthermore, since the adjustment switch 13 of commercially available light source panels 12 is generally also disposed on the light-emitting surface of the light source panel 12, it can be used in conjunction with the structural design of the present invention, eliminating the need for a specially customized light source panel 12, saving production costs and providing excellent practicality.
[0051] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in this embodiment, the housing 10 includes an outer shell 102 and an inner shell 101. The inner shell 101 is arranged in the outer shell 102 by snapping or bonding, and can play a supporting role for the outer shell 102, thereby improving the deformation resistance of the outer shell 102 and extending the service life. A first notch 1021 is provided on the side wall of the outer shell 102 for installing the toggle switch 14, and a second notch 1012 corresponding to the first notch 1021 is provided on the side wall of the inner shell 101. The first notch 1021 and the second notch 1012 are both located on the side of the backlight surface of the light source board 12, and a sliding groove 1022 for the paddle 141 to slide is provided on the outer wall of the outer shell 102 located at the first notch 1021. The paddle 141 is arranged in the sliding groove 1022 and can slide along the sliding groove 1022. 22 slides in the length direction, the slide groove 1022 can limit the sliding distance of the paddle 141, thereby limiting the displacement of the lever 142 in toggling the adjusting handle 131, and providing a sliding trajectory for the paddle 141 to play a guiding role. One end of the lever 142 is connected to the paddle 141, and the other end passes through the first notch 1021 and the second notch 1012 in sequence to toggle the adjusting handle 13. Driven by the paddle 141, the lever 142 toggles the adjusting handle 131 to different positions, thereby achieving color temperature adjustment.
[0052] like Figure 1 、 Figure 2 and Figure 6 As shown, in this embodiment, a plurality of lamp beads 122 of different colors are arranged on one surface of the light source board 12 to form a light-emitting surface, and the plurality of lamp beads 122 are arranged in a circular pattern on the light source board 12 to increase the light-emitting angle of the bulb, thereby increasing the lighting range of the bulb, so as to be suitable for use in a larger space.
[0053] like Figure 3 As shown, in this embodiment, a snap-fitting groove 1421 is provided on the other end of the lever 142. In an alternative embodiment, a groove may be provided on the end surface of the other end of the lever 142 to form the snap-fitting groove 1421 that snaps into the adjustment handle 131. In another alternative embodiment, two levers 142 may be spaced apart and arranged in parallel, with the space between the two levers 142 forming the snap-fitting groove 1421. In this way, the other end of the lever 142 can be snap-fitted to the adjustment handle 131 through the snap-fitting groove 1421 to move the adjustment handle 131.
[0054] like Figure 3 and Figure 6 As shown, in this embodiment, a plurality of hooks 1411 are provided on the paddle 141. The hooks 1411 extend into the first notch 1021 and hook onto the inner wall of the housing 102 to further increase the reliability of the connection between the paddle 141 and the housing 102, prevent the paddle 141 from falling out, and ensure that the paddle 141 can slide smoothly when the paddle 141 is tossed.
[0055] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in this embodiment, the outer sidewall of the open end of the lampshade 11 is recessed inward to form an annular groove 111, and a plurality of clamping blocks 1023 are circumferentially provided on the inner sidewall of one end of the housing 102 to engage with the annular groove 111. Since the annular groove 111 is arranged circumferentially around the open end of the lampshade 11, the clamping blocks 1023 can be inserted into any position of the annular groove 111 to securely engage the lampshade 11 with the housing 102. Pressing the open end of the lampshade 11 toward the housing 102 can achieve a quick engagement and fastening of the lampshade 11 with the housing 102, making assembly convenient.
[0056] In a preferred embodiment, the block 1023 is provided with a guiding inclined surface 10231 for guiding the action of pressing the lampshade 11 toward the housing 102, so as to press the open end of the lampshade 11 into the housing 102, thereby realizing the snap fit between the annular groove 111 and the block 1023.
[0057] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in this embodiment, the inner side wall of one end of the inner shell 101 is recessed outward to form an annular step portion 1011. The light source board 12 is a circular plate. During installation, the light source board 12 is pressed into the inner shell 101 so that the light source board 12 abuts against the step surface of the annular step portion 1011, and the step surface supports the light source board 12. Furthermore, a plurality of limiting grooves 10111 are provided on the inner side wall of the annular step portion 1011, and a plurality of limiting protrusions 123 are protruding from the outer peripheral wall of the light source board 12. The light source board 12 can be snapped into the limiting grooves 10111 through the limiting protrusions 123, thereby being more tightly connected to the inner shell 101 and being able to limit the rotation of the light source board 12 to prevent the structure from loosening.
[0058] In addition, compared with another opposite snap-fit structure design, that is, a recessed limiting groove 10111 is set on the outer peripheral wall of the light source board 12, and a protruding limiting bump 123 is set on the annular step portion 1011, the snap-fit structure design of this embodiment can avoid the problem that the protrusion of the annular step portion 1011 may block the light-emitting surface of the light source board 12, thereby affecting the lighting effect.
[0059] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, a lamp holder 1024 is provided at the other end of the housing 102. The lamp holder 1024 is an interface for installing a light bulb, and can be a bayonet lamp holder or a screw-type lamp holder. The light bulb is connected to electricity through the lamp holder 1024 to play the role of light illumination.
[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
