Description

Technical Field

[0001] This utility model relates to the technical field of bar light sources, and in particular to a modularly combined bar light source. Background Technology

[0002] As the name suggests, a strip light source is a light source arranged in a strip shape.

[0003] The general method of using a strip light source is as follows: place the camera in the direction of the product (usually directly above or in front of the product), and then place an inclined strip light source on one side of the product according to the size of the area to be illuminated (lighting area or supplementary light area). The strip light source emitted by the inclined strip light source hits the product, so that the strip light source covers the required illumination area.

[0004] Currently, the disadvantages of strip light sources are as follows: Strip light sources generally consist of a strip-shaped housing, a PCB strip board, and LED beads mounted on the PCB strip board. The manufacturing length of strip light sources is usually fixed according to specifications, such as the 200X500mm series, 200X800mm series, and 200X1200mm series. This results in a relatively fixed length for strip light sources, preventing customers from freely modularizing and assembling them (in other words, modular assembly, installation, and control of strip light sources are very troublesome). Consequently, customers are limited to choosing certain fixed specifications. The use of fixed-size strip surface light sources for supplemental lighting of products of different sizes can lead to a poor user experience. For example, if the product is large and requires a large illumination area, the strip surface light source cannot meet the illumination area requirements (in which case multiple strip surface light sources need to be pieced together, which is cumbersome). If the product is small and requires a small illumination area, the extra section of the strip surface light source can easily cause stray light interference, resulting in poor uniformity of surface light illumination, high contrast of the illumination area, and one end of the product being brighter.

[0005] Therefore, in summary, the main drawback of current strip light sources is that their length and dimensions are fixed, and their combined use is relatively cumbersome. They cannot adequately meet customers' needs for supplemental lighting of products with different length and dimensions using strip surface light sources. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a modular combination of strip light sources, which includes several light source modules that customers can freely combine in a modular manner, thereby generating strip surface light sources with different illumination lengths, thus meeting customers' needs for supplementary lighting of products with different lengths and sizes.

[0007] To achieve the above objectives, this utility model provides a modularly combined strip light source, including a strip-shaped housing, a plurality of light source modules linearly arranged inside the strip-shaped housing, and a light-transmitting plate installed at one end of the plurality of light source modules. The light source module includes a PCB board, a plurality of light source modules linearly arranged on the PCB board, a first terminal installed on one side of the PCB board and electrically connected to the light source modules, and a second terminal installed on the other side of the PCB board and electrically connected to the light source modules. The light source module includes a light source housing, an LED chip installed inside the light source housing, and an imaging lens installed on one side of the LED chip.

[0011] Preferably, the strip-shaped housing is provided with mounting guide grooves at both the upper and lower ends.

[0014] Preferably, a filter or a light-transmitting sheet is installed on the light-transmitting hole.

[0015] Preferably, the light emission angle of the imaging lens is 25 degrees, 40 degrees, 60 degrees, 80 degrees, or 100 degrees.

[0016] Preferably, a power cord is connected to one side of the strip-shaped housing, and the power cord is electrically connected to several light source modules in sequence.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model is equipped with a fixed strip-shaped housing, inside which several light source modules are linearly arranged.

It is simple to use and greatly saves users' assembly time. Attached Figure Description

[0029] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 The present invention provides a modularly combined strip light source, including a strip housing 1, a plurality of light source modules 2 linearly arranged inside the strip housing 1, and a light-transmitting plate 3 installed at one end of the plurality of light source modules 2. The light source module 2 includes a PCB board 21, a plurality of light source modules 22 linearly arranged on the PCB board 21, a first terminal 23 installed on one side of the PCB board 21 and electrically connected to the light source modules 22, and a second terminal 24 installed on the other side of the PCB board 21 and electrically connected to the light source modules 22. The light source module 22 includes a light source housing 221, an LED chip 222 installed inside the light source housing 221, and an imaging lens 223 installed on one side of the LED chip 222.

[0031] The strip-shaped housing 1 has an installation cavity 10. The upper end of the installation cavity 10 has an upper end plate 11, the lower end of the installation cavity 10 has a lower end plate 12, the left end of the installation cavity 10 is equipped with a left baffle 13, and the right end of the installation cavity 10 is equipped with a right baffle 14.

[0032] The left baffle 13 is connected to one end of the upper end plate 11 and one end of the lower end plate 12 via threaded connections. The right baffle 14 is connected to the other end of the upper end plate 11 and the other end of the lower end plate 12 via threaded connections. A first slot 16 is provided between the upper end plate 11 and the lower end plate 12, and the PCB boards 21 of several light source modules 2 are snapped into the first slot 16. A second slot 17 is provided at one end between the upper end plate 11 and the lower end plate 12, and the light-transmitting plate 3 is snapped into the second slot 17. The second slot 17 facilitates the disassembly and installation of the light-transmitting plate 3, and the first slot 16 facilitates the disassembly and installation of several light source modules 22. Therefore, the first slot 16 and the second slot 17 facilitate the modular combination and disassembly / separation of several light source modules 2 by the user.

[0033] The strip-shaped housing 1 has several linearly arranged heat dissipation fins 18 at one end. The heat dissipation fins 18 facilitate the dissipation of heat generated by the several light source modules 2 on the mounting cavity 10.

[0034] The strip-shaped housing 1 has mounting guide grooves 19 at its upper and lower ends. The mounting guide grooves 19 facilitate the installation of the modular strip light source of this utility model into the designated installation position.

[0035] The light-transmitting plate 3 has two implementation methods:

[0036] The first implementation method: the light-transmitting plate 3 is a transparent glass sheet or a transparent acrylic sheet.

[0037] The advantage of the first implementation is that it retains the luminous flux of all light source modules 22, making the brightness of the strip surface light source higher. However, its uniformity is poor, which can easily lead to concentrated brightness in the middle and poor brightness on both sides.

[0038] The second implementation: The light-transmitting plate 3 is an opaque acrylic sheet. The light-transmitting plate 3 has a plurality of linearly arranged light-transmitting holes 30. The number of light-transmitting holes 30 is the same as the number of imaging lenses 223 of the plurality of light source modules 22. Each light-transmitting hole 30 corresponds one-to-one with an imaging lens 223, and the light-transmitting hole 30 is located at one end of the imaging lens 223. The opaque acrylic sheet is black.

[0039] The advantage of the second implementation is that it reduces the light interference between adjacent light source modules 22, thereby ensuring the uniformity of the strip surface light source.

[0040] Furthermore, a filter (not shown in the attached drawing) or a light-transmitting sheet (not shown in the attached drawing) is mounted on the light-transmitting aperture 30. When the customer has filtering requirements, different filters can be installed to meet the customer's filtering needs.

[0041] Furthermore, the light emission angle of the light source module 22 can be selected by the customer, that is, the light emission angle of the imaging lens 223 is 25 degrees, 40 degrees, 60 degrees, 80 degrees or 100 degrees. This makes it more convenient for users to choose freely, and users can choose different light emission angles to obtain the best effect of the strip surface light source.

[0042] A power cord 4 is connected to one side of the strip-shaped housing 1, and the power cord 4 is electrically connected to several light source modules 22 in sequence.

[0043] Among them, the first terminal 23 is the female terminal and the second terminal 24 is the male terminal. In a plurality of linearly arranged light source modules 2, the second terminal 24 of the first light source module 22 of two adjacent light source modules 22 is plugged into the first terminal 23 of the second light source module 22 to achieve electrical connection. The first terminal 23 or the second terminal 24 of one end of the light source module 22 in the plurality of linearly arranged light source modules 2 is electrically connected to the power line 4.

[0044] The optical principle of a modularly combined strip surface light source according to an embodiment of this utility model is as follows: each optical module is equivalent to a small strip surface light source, and each light source module 22 in each optical module is equivalent to an even smaller strip surface light source. The LED chip 222 of the light source module 22 emits a point light source, which is formed into an even smaller strip surface light source through the imaging lens 223. Several smaller strip surface light sources of the light source modules 22 constitute the small strip surface light source of the optical module. Several small strip surface light sources of the optical modules constitute a modularly combined strip surface light source according to an embodiment of this utility model. Therefore, by freely modularly combining several light source modules 2 to form a strip surface light source with a certain illumination length, it is possible to provide supplementary lighting for products of different lengths and sizes using the strip surface light source.

[0045] The technical advantages of a modularly combined strip surface light source according to an embodiment of this utility model are as follows:

[0046] First: As mentioned above, the free modular combination of several light source modules 2 forms a strip surface light source with a certain illumination length, thereby enabling strip surface light supplementation for products of different lengths and sizes.

[0047] Second: The modular combination and disassembly of several light source modules 2 are simple and easy to operate, greatly improving the user's convenience and allowing users to freely combine and disassemble them to form strip surface light sources with different illumination lengths.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
