Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a courtyard lamp with uniform light emission. Background Art

[0002] Courtyard lamps have the characteristics of diversity and beauty, and can beautify and decorate the environment, so they are also called landscape courtyard lamps. They are mainly used for outdoor lighting in public places such as urban slow lanes, narrow lanes, residential communities, tourist attractions, parks, and squares, which can extend people's outdoor activity time and improve property safety. With the development of the economy and the progress of lighting technology, people's requirements for courtyard lamps are getting higher and higher. At present, in the actual lighting use process of courtyard lamps, the lighting effect is not uniform enough to meet people's actual needs. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defect of insufficiently uniform lighting effect in the prior art, and to provide a courtyard lamp with uniform light emission.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a courtyard lamp with uniform light emission, including a light-emitting component, which is sequentially sleeved with a light homogenizing cover and a protective cover on the outside. The inner wall of the protective cover is distributed with ribs, and both ends of the light-emitting component, the light homogenizing cover and the protective cover are hermetically fixed through a positioning component.

[0006] Further, the light-emitting component includes a central column, a card slot arranged along the outer wall of the central column, and a lamp board arranged in the card slot.

[0007] Further, a through hole is opened in the center of the central column, and heat dissipation ribs are arranged on the inner wall of the through hole.

[0008] Further, the positioning component includes a cover plate, a fixed socket arranged on the inner wall of the through hole, a first bolt passing through the cover plate and screwed with the fixed socket, and a tube body fixed on the cover plate through a second bolt for fixing the light homogenizing cover and the protective cover.

[0009] Further, the positioning component further includes a waterproof cover sleeved on the outside of the light-emitting component and a sealing ring covering between the waterproof cover and the central column. The sealing ring presses against the waterproof cover and the central column through the cover plate.

[0010] Further, baffles are arranged at both ends of the central column.

[0011] Further, a first step is arranged on the tube body for clamping the port of the protective cover.

[0012] Further, a second step is provided on the pipe body for clamping the port of the light homogenizing cover.

[0013] A courtyard lamp with uniform light emission proposed by the present utility model has the beneficial effects that:

[0014] By arranging a light homogenizing cover and a protective cover outside the light-emitting component, the illumination effect of the courtyard lamp is made more uniform. At the same time, the presence of the protective cover can prevent the light homogenizing cover from turning yellow under long-term sunlight irradiation and affecting the illumination effect.

[0015] Secondly, by arranging heat dissipation ribs on the inner wall of the through hole, the heat of the lamp board enters the through hole through the heat dissipation ribs and diffuses towards the top of the central column, improving the heat dissipation effect of the lamp board.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-4 , a courtyard lamp with uniform light emission includes a light-emitting component 1, and a light homogenizing cover 2 and a protective cover 3 are sequentially sleeved outside it. Ribs 301 are distributed on the inner wall of the protective cover 3. Both ends of the light-emitting component 1, the light homogenizing cover 2, and the protective cover 3 are hermetically fixed through a positioning component 4. Preferably, in this embodiment, the light homogenizing cover 2 is implemented by a light diffusing plate, and the protective cover 3 is implemented by a transparent PVC plate.

[0022] By arranging a light homogenizing cover 2 and a protective cover 3 outside the light-emitting component 1, the illumination effect of the courtyard lamp is made more uniform. At the same time, the presence of the protective cover 3 can prevent the light homogenizing cover 2 from turning yellow under long-term sunlight irradiation and affecting the illumination effect.

[0023] In an alternative embodiment of the present utility model, the light-emitting component 1 includes a central column 101, a card slot 102 provided along the outer wall of the central column 101, and a lamp board 103 disposed in the card slot 102. Preferably, the number of card slots 102 in this embodiment is seven; by providing seven lamp boards 103 on the outer wall of the central column 101, the light emitted by the lamp boards 103 irradiates around from multiple directions through the light homogenizing cover 2 and the protective cover 3, and the lighting effect is more uniform.

[0024] In an alternative embodiment of the present utility model, in order to improve the heat dissipation effect of the lamp board 103, a through hole 104 is provided in the center of the central column 101, and heat dissipation ribs 105 are provided on the inner wall of the through hole 104. The heat of the lamp board 103 enters the through hole 104 through the heat dissipation ribs 105 and diffuses towards the top of the central column 101.

[0025] In an alternative embodiment of the present utility model, the positioning component 4 includes a cover plate 401, a fixed socket 402 provided on the inner wall of the through hole 104, a first bolt 403 passing through the cover plate 401 and screwed to the fixed socket 402, and a tube body 405 fixed to the cover plate 401 by a second bolt 404 for fixing the light homogenizing cover 2 and the protective cover 3. After the tube body 405 is fixed to the cover plate 401, the positions of the light homogenizing cover 2 and the protective cover 3 are fixed by the tube body 405. At the same time, the cover plate 401 is fixed to the central column 101, thereby realizing the fixation of the light-emitting component 1, the light homogenizing cover 2, and the protective cover 3.

[0026] In an alternative embodiment of the present utility model, the positioning component 4 further includes a waterproof cover 406 sleeved outside the light-emitting component 1 and a sealing ring 407 covering between the waterproof cover 406 and the central column 101. The sealing ring 407 abuts against the waterproof cover 406 and the central column 101 through the cover plate 401. After the cover plate 401 is fixed to the central column 101, the sealing ring 407 is squeezed and abuts against the waterproof cover 406 and the central column 101, thereby preventing water from entering the card slot 102.

[0027] In an alternative embodiment of the present utility model, baffles 408 are provided at both ends of the central column 101. By providing the baffles 408, the cover plate 401 can be limited, thereby preventing the sealing ring 407 from being overly squeezed by the cover plate 401.

[0028] In an alternative embodiment of the present utility model, a first step 409 is provided on the tube body 405, which is used for clamping the port of the protective cover 3. By inserting the two ports of the protective cover 3 into the first step 409 respectively, the fixation of the protective cover 3 is realized.

[0029] In an alternative embodiment of the present utility model, a second step 410 is provided on the tube body 405, which is used for clamping the port of the light homogenizing cover 2. By inserting the two ports of the light homogenizing cover 2 into the second step 410 respectively, the fixation of the light homogenizing cover 2 is realized.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
