Description

Technical Field

[0001] This utility model relates to the technical field of lamp housings, and in particular to a lamp housing with adjustable light transmittance. Background Technology

[0002] Lighting fixtures are a general term for lighting tools, consisting of components that fix a light source and wiring accessories, including types such as toy lamps, chandeliers, table lamps, and wall lamps. Their function has expanded from basic lighting to a combination of practicality and decoration, and they are widely used in home, commercial, and industrial settings. They must meet national safety standards and pass 3C certification. As electrical products, lighting fixtures are explicitly classified as independent materials that need to be purchased separately in home decoration projects. The lamp housing not only houses the lamp but also provides effective protection for the lamp body.

[0003] Existing toy lamp housings can only protect the lamp body, but they cannot adjust the light transmittance of the lamp housing, resulting in the brightness of the toy being unsuitable for various scenarios and limiting the applicability of the lamp housing. Utility Model Content

[0004] The main purpose of this utility model is to provide a lamp housing with adjustable light transmittance, which can effectively solve the problem of not being able to adjust the light transmittance of the lamp housing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable light-transmitting lamp housing includes a lower housing, a light-transmitting component movably connected to the upper part of the lower housing, a lamp body fixedly installed in the middle of the inner cavity of the lower housing, a supporting mechanism fixedly connected to the bottom wall of the inner cavity of the lower housing, a winding mechanism symmetrically fixedly connected to the lower side inside the supporting mechanism, an adjustment mechanism fixedly connected to the left and right sides of the two winding mechanisms, and a light-shielding mechanism provided on the outside of the two winding mechanisms.

[0007] Preferably, the light-transmitting component includes a clamping sleeve, and a light-transmitting cover plate is fixedly connected to the upper part of the outer surface of the clamping sleeve.

[0008] Preferably, the bearing mechanism includes two bearing housings, and the upper left and right sides of the outer surfaces of the two bearing housings are jointly fixedly connected to an arc-shaped frame.

[0009] Preferably, the winding mechanism includes two support plates, with a rotating roller rotatably connected to one end of each support plate that is close to the other, and the two support plates are fixedly connected to the left and right sides of the corresponding outer surface of the bearing housing.

[0010] Preferably, the adjusting mechanism includes a connecting plate, a cross-shaped lever is fixedly connected to the center of the connecting plate, and the left end of the outer surface of the connecting plate is fixedly connected to the right end of the outer surface of the corresponding rotating roller.

[0011] Preferably, the light-blocking mechanism includes a frosted fabric curtain, with a limit strip fixedly connected to the middle of the upper output end of the frosted fabric curtain, and the left and right sides of the frosted fabric curtain are slidably connected to the inner cavities of two arc-shaped frames, and the lower part of the frosted fabric curtain is installed and fixed to the outer surface of the corresponding rotating roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model enables easy connection to the upper part of the lower housing through the light-transmitting component. At the same time, the supporting mechanism can support the two winding mechanisms, improving the practicality of the device. The winding mechanism can support the two light-shielding mechanisms. Under the action of the adjustment mechanism, the light-shielding mechanism can be wound up. Furthermore, the light-shielding mechanism can adjust the brightness of the lamp body through the light-transmitting component, improving the practicality and versatility of the device.

[0014] 2. This utility model drives the rotating roller to rotate by turning the connecting plate, thereby rolling up the frosted cloth curtain that was originally blocked under the light-transmitting cover plate. This makes the lamp housing suitable for toys with different light intensities. During this process, the limiting strip can prevent the frosted cloth curtain from being completely rolled up into the inner cavity of the carrier shell, making it difficult to unfold the frosted cloth curtain again, thus improving the practicality and versatility of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 As shown, an adjustable light-transmitting lamp housing includes a lower housing 1. A light-transmitting component 2 is movably connected to the upper part of the lower housing 1, facilitating connection with the upper part of the lower housing 1. A lamp body 3 is installed and fixed in the middle of the inner cavity of the lower housing 1. A supporting mechanism 4 is fixedly connected to the bottom wall of the inner cavity of the lower housing 1, which supports two winding mechanisms 5. The winding mechanisms 5 are symmetrically fixedly connected to the lower side of the supporting mechanism 4, which supports two light-shielding mechanisms 7. Adjustment mechanisms 6 are fixedly connected to the left and right sides of the two winding mechanisms 5, which can wind up the light-shielding mechanisms 7. Light-shielding mechanisms 7 are provided on the outside of the two winding mechanisms 5, which can adjust the brightness of the lamp body 3 through the light-transmitting component 2.

[0022] For ease of connection with the upper part of the lower housing 1, please refer to... Figure 2 The light-transmitting component 2 includes a clamping sleeve 21, and a light-transmitting cover plate 22 is fixedly connected to the upper part of the outer surface of the clamping sleeve 21, which can realize the function of transmitting the light emitted by the lamp body 3 to the outside.

[0023] To achieve the purpose of supporting the two winding mechanisms 5, refer to... Figure 3 The supporting mechanism 4 includes two supporting shells 41. The upper left and right sides of the outer surface of the two supporting shells 41 are fixedly connected to an arc-shaped frame 42, which can guide the opening and closing of the frosted fabric curtain 71.

[0024] To achieve the purpose of supporting the two shading mechanisms 7, see [reference needed]. Figure 4 The winding mechanism 5 includes two support plates 51. The ends of the two support plates 51 that are close to each other are rotatably connected to a rotating roller 52, which can realize the function of winding and winding the frosted fabric curtain 71. The two support plates 51 are fixedly connected to the left and right sides of the outer surface of the corresponding bearing housing 41.

[0025] To achieve the purpose of winding up the light-blocking mechanism 7, refer to... Figure 3 The adjusting mechanism 6 includes a connecting plate 61, with a cross-shaped lever 62 fixedly connected to the middle of the connecting plate 61. This lever can drive the support plate 51 to roll up the frosted fabric curtain 71 when rotating. The left end of the outer surface of the connecting plate 61 is fixedly connected to the right end of the outer surface of the corresponding rotating roller 52.

[0026] To achieve the purpose of adjusting the brightness of the light-transmitting component 2 of the lamp body 3, refer to... Figure 4The light-blocking mechanism 7 includes a frosted fabric curtain 71. A limit strip 72 is fixedly connected to the middle of the upper output end of the frosted fabric curtain 71, which can prevent the frosted fabric curtain 71 from being completely rolled into the inner cavity of the bearing sleeve 41 during winding. The left and right sides of the frosted fabric curtain 71 are slidably connected to the inner cavities of the two arc-shaped frames 42. The lower part of the frosted fabric curtain 71 is installed and fixed on the outer surface of the corresponding rotating roller 52.

[0027] It should be noted that the model number of the lamp body 3 in this utility model is SMD0603. The specific installation method, circuit connection method and control method of the lamp body 3 are all conventional designs, and this utility model will not elaborate on them in detail.

[0028] The working principle of this utility model is as follows: The adjustable light transmittance lamp housing drives the connecting plate 61 and the rotating roller 52 to rotate by rotating the cross-shaped dial 62, so that the frosted cloth curtain 71 wrapped on the rotating roller 52 can slide and unfold or roll up along the arc frame 42. When the frosted cloth curtain 71 is unfolded, its frosted surface reduces the light intensity transmitted through the light-transmitting cover plate 22 of the lamp body 3 through the scattering effect, thereby realizing the adjustment of brightness. When rolled up, the light of the lamp body 3 is completely transmitted, and the limiting strip 72 can prevent the frosted cloth curtain 71 from being completely rolled into the inner cavity of the bearing sleeve 41.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
