Description

Technical Field

[0001] The utility model relates to the technical field of LED packaging structure design, in particular to a side-emitting LED packaging structure. Background Art

[0002] LED packaging structure refers to the packaging method and structural design of LED chips, which directly affects the optical performance, thermal management capabilities and external environment adaptability of LED lamps. It is generally divided into the following types: DIP packaging (dual in-line package): This packaging structure is suitable for manual welding and is mainly used for display screens and some simple display applications. SMD packaging (surface mount packaging): The packaging structure is small and suitable for automated production. It is often used for indicator lights and backlight sources of electronic products. COB packaging (chip packaging): It integrates multiple LED chips together to form an overall light source with uniform light distribution and good thermal management performance. It is suitable for lighting applications. CSP packaging (chip scale packaging): It is a packaging technology that directly packages LED chips on a substrate. It has a smaller size and higher brightness efficiency. It is suitable for scenes such as mobile phone flashlights and car lights. The above are some common packaging structures of LEDs. Each packaging structure has its applicable scenes and characteristics.

[0003] The existing patent CN201549498U discloses a side-emitting LED packaging structure, which is a white light mixed by three chips of RGB primary colors: red, green, and blue, with high color rendering performance and high light extraction efficiency. At the same time, full color can be achieved by adjusting the driving circuit. The LCD panel using this packaging structure displays bright colors. The red, green, and blue chips are arranged in a straight line, taking into account the space size limitation and the need for color mixing. The utility model can be widely used in lighting fields such as LCD panels and advertising light boxes, and can achieve full-color gamut color display, and can also dynamically adjust color changes;

[0004] However, in this patent, the adjustment of LED light is achieved by setting a colored chip, but the meaning of side emission in the side-emitting LED sealing structure is to emit light around or from the side of the light source, rather than just from one direction or surface. The emitted light is more diffuse. Therefore, in actual use, the irradiation distance of the side-emitting LED lamp is limited and cannot meet the needs of long-distance use. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to provide a side-emitting LED packaging structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a side-emitting LED packaging structure comprises a base and an LED lamp body, and a mounting layer is arranged on the base;

[0007] The LED lamp body is fixedly connected to the inner wall of the mounting layer, a lens layer is fixedly connected to the side of the mounting layer away from the base, a first lens is fixedly connected to the inner wall of the lens layer close to the base, a focusing plate is fixedly connected to the top of the lens layer, and a second lens is fixedly connected to the side of the focusing plate close to the base.

[0008] As a preferred implementation manner: a heat-conducting column is fixedly connected to the bottom of the installation layer, and the heat-conducting column is fixedly connected to the base.

[0009] The beneficial effect of adopting the above further solution is that by providing the heat-conducting column, the heat emitted by the LED lamp into the installation layer can be conducted to the base and then dissipated to the outside.

[0010] As a preferred implementation, a reflective plate is sleeved on the lens layer, and a reflective coating is provided on a side of the reflective plate close to the lens layer.

[0011] The beneficial effect of adopting the above further solution is that by providing a reflective plate, light is prevented from being lost in the lens layer and affecting use.

[0012] As a preferred implementation, the base, the heat-conducting column and the mounting layer are all configured as aluminum alloy structures.

[0013] The beneficial effect of adopting the above further scheme is that the aluminum alloy material has good thermal conductivity. By setting the base, the thermal conductive column and the mounting layer to be aluminum alloy material, the heat in the mounting layer can be dissipated to avoid excessive heat damaging the LED lamp.

[0014] As a preferred implementation, a mounting groove is formed on the inner wall of the mounting layer, and the LED lamp body is fixedly connected in the mounting groove on the mounting layer.

[0015] The beneficial effect of adopting the above further scheme is: by providing a mounting groove, the LED lamp is arranged in the mounting groove. When in use, the LED lamp will emit light into the mounting layer, and the light will be reflected out through the reflection of the inner wall of the safety layer, and the light will be softer.

[0016] As a preferred implementation, the inner wall and the bottom of the installation layer are both provided with reflective paper.

[0017] The beneficial effect of adopting the above further solution is: by arranging reflective paper on the inner wall and the bottom of the installation layer, it is prevented that light is lost from the installation layer and affects the light emission.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. The utility model is provided with a first lens and a second lens. When in use, the light will first be emitted from the installation layer, and then reflected upward by the reflective layer in the installation layer. The reflected light will first be emitted into the lens layer through the first lens, and then refracted by the lens in the lens layer, and then focused and diverged by the focusing plate. After the light is refracted by the lenses twice and then focused by the focusing plate, the light is more concentrated and can be irradiated at a longer distance, which can meet the use requirements of a longer distance.

[0020] 2. In the utility model, by providing a heat-conducting column, when in use, the heat generated in the installation layer will be conducted to the heat-conducting column through the installation layer, and then conducted to the base by the heat-conducting column, so that the heat is dissipated and the LED lamp is prevented from being damaged by excessive heat in the installation layer.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1-4 As shown, a side-emitting LED packaging structure includes a base 1 and an LED lamp body 12, and a mounting layer 2 is provided on the base 1;

[0030] The LED lamp body 12 is fixedly connected to the inner wall of the mounting layer 2, a lens layer 4 is fixedly connected to the side of the mounting layer 2 away from the base 1, a first lens 3 is fixedly connected to the inner wall of the lens layer 4 close to the base 1, a focusing plate 7 is fixedly connected to the top of the lens layer 4, and a second lens 6 is fixedly connected to the side of the focusing plate 7 close to the base 1. By providing two lenses, light can be focused, which solves the problem that the side-emitting LED structure emits scattered light during use and cannot meet the needs of long-distance use.

[0031] When in use, the light will first be emitted from the installation layer 2, and then reflected upward by the reflective layer in the installation layer 2. The reflected light will first be emitted into the lens layer 4 through the first lens 3, and then refracted by the lens in the lens layer 4, and then focused and diverged by the focusing plate 7. After the light is refracted twice by the lens and then focused by the focusing plate 7, the light is more concentrated and can be irradiated at a longer distance, which can meet the needs of longer distance use.

[0032] Example 2

[0033] like Figure 1-4 As shown, the bottom of the mounting layer 2 is fixedly connected with a heat-conducting column 11, and the heat-conducting column 11 is fixedly connected to the base 1. By providing the heat-conducting column 11, the heat emitted from the LED lamp to the mounting layer 2 can be conducted to the base 1, and then dissipated to the outside, so as to control the temperature in the mounting layer 2 and prevent the temperature from being too high and affecting the normal operation of the LED lamp;

[0034] The lens layer 4 is sleeved with a reflective plate 5 , and a reflective coating is provided on a side of the reflective plate 5 close to the lens layer 4 . The reflective plate 5 is provided to prevent light from being lost in the lens layer 4 and affecting use.

[0035] The base 1, the heat-conducting column 11 and the mounting layer 2 are all configured as aluminum alloy structures. The aluminum alloy material has a good thermal conductivity. By configuring the base 1, the heat-conducting column 11 and the mounting layer 2 as aluminum alloy materials, the heat generated in the mounting layer 2 during use will be conducted to the base 1 through the heat-conducting column 11, and then dissipated to the outside by the base 1, thereby dissipating the heat in the mounting layer 2 and preventing the LED lamp from being damaged by excessive heat.

[0036] The inner wall of the mounting layer 2 is provided with a mounting groove, and the LED lamp body 12 is fixedly connected in the mounting groove on the mounting layer 2. By providing the mounting groove, the LED lamp is arranged in the mounting groove. When in use, the LED lamp will emit light into the mounting layer 2, and the light will be reflected out by the inner wall of the safety layer, and the light will be softer. After the subsequent lens focuses the light, the light diverges more evenly and can meet the long-distance use requirements;

[0037] The inner wall and the bottom of the installation layer 2 are both provided with reflective paper. By providing the reflective paper on the inner wall and the bottom of the installation layer 2, it is prevented that light is lost from the installation layer 2, causing light leakage and affecting use.

[0038] Working principle:

[0039] like Figure 1-4 As shown, firstly, by providing the first lens 3 and the second lens 6, when in use, the light will first be emitted from the mounting layer 2, and then reflected upward by the reflective layer in the mounting layer 2, and the reflected light will first be emitted into the lens layer 4 through the first lens 3, and then refracted by the lens in the lens layer 4, and then focused and diverged by the focusing plate 7. After the light is refracted by the lenses twice and then focused by the focusing plate 7, the light is more concentrated, and the irradiation distance is longer, which can meet the use requirements of a longer distance;

[0040] By providing the heat-conducting column 11, when in use, the heat generated in the installation layer 2 will be conducted to the heat-conducting column 11 through the installation layer 2, and then conducted to the base 1 by the heat-conducting column 11, so that the heat is dissipated, avoiding excessive heat in the installation layer 2 to damage the LED lamp and affect subsequent use.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
