Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and more specifically, to a linear extended LED lamp. Background Technology

[0002] LED lights, being solid-state cold light sources, are widely used in the street lighting industry due to their environmentally friendly and pollution-free nature, low power consumption, high luminous efficiency, and long lifespan. Traditional LED lights, however, require the manufacture of LED strips of varying lengths depending on the required power and lighting range. This limits their application scenarios and necessitates the use of various PCB boards of different lengths, resulting in high overall costs. For occasional scenarios requiring extra-long LED lights, custom-made extra-long LED strips are necessary, further restricting their applicability.

[0003] Taking a 60W light fixture as an example, if an integrated PCB layout is required, the following disadvantages will be encountered:

[0004] (1) There are many PCB part numbers.

[0005] (2) Multiple warehouse locations need to be managed.

[0006] (3) It is inconvenient to prepare goods.

[0007] (4) Long delivery cycle.

[0008] Therefore, this utility model provides a linear extended LED lamp. Utility Model Content

In the representation of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0049] For the purpose of clearly describing this application, devices that are not relevant to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0050] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0051] When we say that a device is "above" another device, this can mean that it is directly above the other device, or it can mean that other devices are present in between. Conversely, when we say that a device is "directly" "above" another device, there are no other devices present in between.

[0052] Although the terms first, second, etc., are used in some instances herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of features, steps, operations, elements, components, items, kinds, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups.

Figure 2 This is a second-view perspective perspective view of the linear extended LED lamp of this utility model. Figure 3 This is an exploded view of the linear extended LED lamp of this utility model. Figure 4 This is a schematic diagram of the LED module interconnection in the linear extended LED lamp of this utility model. Figures 1 to 4As shown, the linear extended LED lamp of this utility model is characterized by comprising: a strip-shaped lamp cover 7, a strip-shaped heat sink 4, several LED modules 9, a junction box 2, and a side cover 8. The strip-shaped lamp cover 7 has a heat sink groove 6 on each of its two sides; several LED modules 9 are serially spliced ​​along one side of the strip-shaped heat sink 4, and each LED module 9 has a solderless connector 91 at both ends. The solderless connectors 91 of adjacent LED modules 9 are connected via a module connector 92. The two sides of the strip-shaped heat sink 4 slide along the heat sink groove 6 to enter the strip-shaped lamp cover 7; the junction box 2 and the side cover 8 are respectively sealed to both ends of the strip-shaped lamp cover 7. This utility model's linear extended LED lamp can provide multiple power ranges, with different lamp lengths corresponding to different power ranges. Conventional designs involve creating a PCB layout for each power range's corresponding LED module. When there are many power ranges, a corresponding number of LED modules are required. The LED light source module in this utility model adopts a modular splicing design. Compared to the conventional single-corresponding design, this solution can reduce the number of LED module types. That is, one size of LED module can meet the needs of lamp products with multiple power ranges, reducing warehouse space management, facilitating inventory preparation, and thus shortening the product delivery cycle.

[0056] In a preferred embodiment, adjacent LED modules 9 are electrically connected through solderless connectors 91 and module connectors 92, so that the LED modules 9 can form a light-emitting whole, equivalent to a whole LED light strip, but not limited thereto.

[0057] In a preferred embodiment, one side of the LED module 9 is provided with light-emitting LED beads, and the other side is in contact with the strip heat sink 4 to enhance the heat dissipation effect of the LED module 9, but this is not a limitation.

[0058] In a preferred embodiment, the junction box 2 has an inlet / outlet connector 1 on the first side and a metal welding ring 3 on the second side that is ultrasonically welded to the end of the strip lamp cover 7 to enhance the sealing performance and extend the service life of the linear extended LED lamp, but this is not a limitation.

[0059] In a preferred embodiment, the side cover 8 is sealed to the end of the strip lamp cover 7 by ultrasonic welding via a metal welding ring 3, in order to enhance the sealing performance and extend the service life of the linear extended LED lamp, but this is not a limitation.

[0060] In a preferred embodiment, the strip lamp cover 7 has a light-emitting side and a connection side facing away from each other. The light emission direction of the LED module 9 is emitted outward through the light-emitting side of the strip lamp cover 7, but this is not a limitation.

[0061] In a preferred embodiment, a mounting bracket 5 is provided at each end of the light-emitting side to adapt to different installation scenarios, but is not limited thereto.

[0062] In a preferred embodiment, the light-emitting side is also provided with a multi-size mounting base 10 to adapt to different installation scenarios, but is not limited thereto.

[0063] In a preferred embodiment, the light-emitting side is further provided with a 45° mounting bracket 11 to adapt to different installation scenarios, but is not limited thereto.

[0064] In a preferred embodiment, the light-emitting side is further provided with a magnet mounting component 12 to adapt to different installation scenarios, but is not limited thereto.

[0065] Taking a 60W lamp as an example, if the split PCB layout of this invention is required, it will have the following advantages:

[0066] (1) All models have only one PCB part number.

[0067] (2) Only one storage location is needed for management.

[0068] (3) It has strong commonality and can be stocked.

[0069] (4) Shorten the delivery cycle.

[0070] In summary, the purpose of this utility model is to provide a linearly extended LED light that can flexibly change the length of the light strip by linearly connecting LED modules, thereby achieving the expandability of the light source. This facilitates the repeated use of the same LED module and reduces the overall cost of various LED lights.
