Description

Technical Field

[0001] This utility model belongs to the field of energy-saving lamp technology, specifically relating to a high-efficiency energy-saving lamp. Background Technology

[0002] Existing energy-saving lamps consist of a base, a lamp panel mounted on the base, and a lamp housing connected to the base. Several toothed strips are distributed on the two inner walls of the lamp housing, utilizing multiple reflections or refractions to achieve a uniform and soft light emission. However, the area between the back of the lamp panel and the base is not fully utilized, leading to light loss and reduced light efficiency. Utility Model Content

[0003] Based on the aforementioned shortcomings and deficiencies in the existing technology, the purpose of this utility model is to provide a high-efficiency energy-saving lamp.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A high-efficiency energy-saving lamp includes a base and a lamp body mounted on the base. The lamp body includes a columnar lamp shell and a light-emitting plate installed inside the lamp shell. The light-emitting plate extends longitudinally along the lamp shell, and the cross-section of the inner wall of the lamp shell is a wavy annular structure.

[0006] The front of the light-emitting panel is the light-emitting surface, and the back of the light-emitting panel is a convex arc structure; the lamp housing is provided with a light outlet at the position directly opposite the light-emitting surface of the light-emitting panel, and the light outlet is equipped with a lens;

[0007] The inner wall of the lamp housing, the back of the light-emitting panel, and the surrounding area are all provided with a reflective coating.

[0008] As a preferred embodiment, the light-emitting panel is installed inside the lamp housing by a number of support columns.

[0009] As a preferred embodiment, the support column has a hollow structure, and the power line is connected to the light-emitting plate through the hollow through hole of the support column.

[0010] As a preferred embodiment, the outer surface of the support column is provided with a reflective coating.

[0011] As a preferred embodiment, the lamp housing is provided with a heat dissipation pipe on the outside, with the openings at both ends of the heat dissipation pipe located inside the lamp housing.

[0012] As a preferred embodiment, the outer diameter of the lens is equal to the outer diameter of the lamp housing.

[0013] As a preferred embodiment, the inner surface of the lens is a plane.

[0014] As a preferred embodiment, the lens is snapped into the light outlet of the lamp housing.

[0015] As a preferred embodiment, the lamp housing is bonded, screwed, or integrally formed with the base.

[0016] As a preferred embodiment, the columnar lamp housing has an axisymmetric structure.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] (1) The light emitted by the light-emitting plate of this utility model passes directly through the lens, and the remaining light is diffusely reflected through the wavy inner side of the lamp housing, and finally reaches the lens. Some light is diffusely reflected between the wavy inner side and the reflective coating of the arc structure on the back of the light-emitting plate, and finally reaches the lens, which effectively reduces the loss of light, improves the efficiency of light use, and increases the brightness.

[0019] (2) This utility model achieves more uniform light focused onto the lens through multiple diffuse reflections.

[0020] (3) The high-efficiency energy-saving lamp of this utility model will cause heat to focus after long-term use, affecting its lifespan. The heat dissipation pipe is connected to the lamp housing, and the internal heat is dissipated through the heat dissipation pipe, thus improving the heat dissipation effect. Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the structure of the high-efficiency energy-saving lamp of Embodiment 1 of this utility model. Detailed Implementation

[0022] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0023] Example 1:

[0024] like Figure 1 As shown, the high-efficiency energy-saving lamp of this embodiment includes a base 1 and a lamp body 2 mounted on the base 1.

[0025] In this embodiment, the lamp body 2 is a light-emitting component, specifically including a cylindrical lamp housing 3 and a light-emitting plate 4 installed inside the lamp housing 3. Specifically, the light-emitting plate 4 is installed inside the lamp housing 3 by a number of support columns 5. The support columns 5 have a hollow structure, which facilitates concealed wiring. That is, the power line is connected to the light-emitting plate 4 through the hollow through hole of the support column 5 to realize the power supply of the light-emitting plate 4.

[0026] The lamp housing 3 and the base 1 are fixedly installed by bonding, screwing or integral molding, or other commonly used fixed installation structures can also be used.

[0027] In this embodiment, the lamp housing 3 has an overall axially symmetrical structure, which ensures the uniformity of light output.

[0028] In this embodiment, the light-emitting plate 4 extends along the longitudinal direction (i.e., the length direction) of the lamp housing 3, and the cross-section of the inner wall of the lamp housing is a wavy annular structure L, which is beneficial to improving the diffuse reflection effect.

[0029] The front (top) surface of the light-emitting plate 4 is the light-emitting surface, and the back surface of the light-emitting plate 4 is a convex arc structure H. The lamp housing 3 is provided with a light outlet at the position (top) opposite the light-emitting surface of the light-emitting plate 4, and the light outlet is provided with a lens 6. In this embodiment, the inner surface of the lens 6 is a plane, and the outer diameter of the lens 6 is equal to the outer diameter of the lamp housing 3, which facilitates easy docking and avoids affecting the light output effect.

[0030] In this embodiment, the lens 6 is snapped into the light outlet of the lamp housing, for example, by fastening, which facilitates the disassembly and replacement of the lens 6.

[0031] In this embodiment, the inner wall of the lamp housing 3, the back and sides of the light-emitting plate 4, and the outer surface of the support column 5 are all provided with reflective coatings to enhance the reflection effect.

[0032] In this embodiment, some of the light generated by the light-emitting plate passes directly through the lens, while the rest is diffusely reflected through the wavy inner surface before finally reaching and being focused on the lens. Some of the light is diffusely reflected between the wavy inner surface and the light-emitting plate and the support base before finally reaching and being focused on the lens, effectively reducing light loss and increasing brightness. Moreover, after multiple diffuse reflections, the light focused on the lens is more uniform.

[0033] In addition, the lamp housing 3 of this embodiment is provided with a heat dissipation pipe 7 on the outside. The openings at both ends of the heat dissipation pipe 7 extend into the lamp housing 3. The heat dissipation pipe is a hollow body, and the heat inside the lamp housing 3 is dissipated through the heat dissipation pipe.

[0034] Example 2:

[0035] The high-efficiency energy-saving lamp in this embodiment differs from that in Embodiment 1 in that:

[0036] The design omits heat pipes to meet the needs of different applications;

[0037] Other structures can be found in Example 1.

[0038] Example 3:

[0039] The high-efficiency energy-saving lamp in this embodiment differs from that in Embodiment 1 in that:

[0040] To enhance the heat dissipation effect of the heat pipes, the heat pipes can be designed as threaded pipes;

[0041] Other structures can be found in Example 1.

[0042] The above description is only a detailed explanation of the preferred embodiments and principles of this utility model. For those skilled in the art, there may be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the protection scope of this utility model.
