DETAILED DESCRIPTION OF THE INVENTION
[0012] Hereinafter, specific embodiments of the present invention will be described in further detail based on the drawings. It should be understood that the description of the embodiments of the present invention is not intended to limit the protection scope of the present invention.
[0013] As shown in FIG.1~7, the lamp suitable for automated production in this embodiment includes a lamp holder 100, a light source assembly 200, and an end cover 300. The lamp holder 100 is provided with an installation cavity 101 for installing the light source assembly 200, and the installation cavity 101 is provided with an installation opening 102, and the end cover 300 is used to encapsulate the installation opening 102. In addition to the light source assembly, electrical components are also installed in the installation cavity 101. In some cases, the electrical components and the light source assembly 200 are coupled with each other. In this embodiment it focuses on the structure and installation method of the end cover 300. The specific forms of other parts are only shown as example in this embodiment. Of course, they can also be applied to other types of lamps, such as strip lamp, shot lamp, downlamp, etc.
[0014] The cross-sectional shape of the column 301 may be round-like or other shapes, such as polygonal, triangular, and the like.
[0015] In this embodiment, the lamp holder 100 is provided with a fixing hole 103, and the end cover 300 is provided with a column 301 that is interference-fitted with the fixing hole 103 to achieve a fixed connection. The fixed connection is realized by inserting the column 301 into the fixing hole 103, the assembly action is less, the direction is single, and automation can be conveniently realized.
[0016] In this embodiment, the middle section of the column 301 expands radially, so that it can take the shape of an elliptical sphere with small ends and a large middle, that is, a structure with large middle and small ends which gradual change from the middle to both ends, which is not only easier to align with the fixing hole 103, but also easier to insert and assemble.
[0017] In order to make the assembly of the fixing hole 103 and the column 301 more firm, in this embodiment, the hardness of the fixing hole 103 is greater than that of the column 301 and its orifice is a cut. In this embodiment, when assembling, the orifice is used as a cut, and the outer wall of the column 301 is cut. After cutting, the assembly can be tighter and stronger. The orifice as a cut is generally not chamfered, so that the outer wall of the column 301 can be cut by making the orifice sharp.
[0018] In order to prevent the cut chips from accumulating at the root of the column 301, in this embodiment, the radial dimension of the root of the column 301 is smaller than the fixing hole 103. As a result, a gap 400 is formed between the root of the column 301 and the inner wall of the fixing hole 103, and the gap 400 is used to accommodate the cut chips, prevent the cut chips from accumulating outside the fixing hole 103, and improve the fixing effect.
[0019] In order to facilitate manufacturing, the lamp holder 100 is made of metal material, generally aluminum alloy. Further, the end cover 300 is made of plastic or nylon material, which has certain elasticity and strength and has hardness less than that of most metals, for that the aforementioned cutting process can be completed.
[0020] In order to make the assembly more reliable and prevent the column 301 from being broken due to misalignment, the end cover 300 is provided with a guide block 302 close to the column 301, and the length of the guide block 302 is longer than the column 301. The lamp holder 100 is provided with a guide groove 108 that is matched with the guide block 302. When assembling, the guide block 302 and the guide groove 108 are first matched to align the assembly, and then the column 301 and the fixing hole 103 are connected.
[0021] The structure and assembly of the end cover 300 of this embodiment can be applied to various types of lamps. The lamp of this embodiment is a bar-shaped lamp, the lamp holder 100 is a bar, and the end cover 300 is used to encapsulate installation opening 102 at the end of the lamp holder 100. Both ends of the lamp holder 100 of this embodiment need to be encapsulated, and the encapsulated method is the same, and one end is described below as example.
[0022] The lamp holder 100 of this embodiment is a profile and its cross-section is U-shaped, and it includes a bottom surface 104 and two opposite side surfaces 105. The profile has a simple shape and low manufacturing cost. The inner side of the side surface 105 is provided with the fixing hole 103, and the depth direction of the fixing hole 103 is the same as the length direction of the lamp holder 100. With this arrangement, the insertion direction of the fixing hole 103 and the column 301 can be the same as the length direction of the lamp holder 100.
[0023] To facilitate manufacturing, the fixing hole 103 extends to both ends of the side surface 105 along the depth direction. Further, both side surfaces 105 are provided with the fixing holes 103, and the end cover 300 is provided with two columnes 301 respectively matched with the fixing holes 103. The number of the columnes 301 on the end cover 300 can be set according to the size and shape of the installation opening 102. In this embodiment, there are two columnes 301.
[0024] In addition, if the depth of the closed hole on the circumference is too large, it is difficult to process. For this reason, the fixing hole 103 in this embodiment is provided with a slit 1031 on the circumference, and the side wall of the column 301 is provided with a reinforcing rib 3011, the reinforcing rib 3011 is inserted into the slit 1031 during assembly.
[0025] The light source assembly 200 includes a strip-shaped circuit board 201, a light source 202 arranged on the strip-shaped circuit board 201 and a strip-shaped optical element 203. The strip-shaped optical element 203 may be a light distribution lens or a simple lampshade.
[0026] The two side surfaces 105 are provided with first grooves 106 which are arranged opposite to each other and extend to both ends along the length direction. The circuit board 201 penetrates into the first groove 106 from the installation opening 102. The two side surfaces 105 are provided with second grooves 107 which are arranged opposite to each other and extend to both ends along the length direction. The two sides of the strip-shaped optical element 203 are provided with clamping edges, which penetrate the second grooves 107 from the installation opening 102. With the above structure it is easy to install the circuit board 201 and the strip-shaped optical element 203, and then install the end cover 300 to complete the entire lamp installation.
[0027] In this embodiment, the fixing hole 103 is arranged below the first groove 106, and the guide groove 108 is located below the fixing hole 103.
[0028] In this embodiment, a socket 2011 is provided at the end of the circuit board 201, and the socket 2011 is arranged on the back of the circuit board 201, and the end cover 300 is provided with a plug-in groove aligned with the jack of the socket 2011, and the two columnes 301 distributed on both sides of the plug-in groove 303.
[0029] The above disclosure has been described by way of example and in terms of exemplary embodiment, and it is to be understood that the disclosure is not limited thereto.
