Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a supplementary lighting lamp for fruit and vegetable plants. Background Technology

[0002] Under-plant grow lights are a type of lighting fixture primarily used to supplement the light exposure of fruit-bearing crops, thereby accelerating fruit growth and ripening, and promoting anthocyanin synthesis and color change. However, traditional under-plant grow lights are either suspended from the top of the plant, with the light shining downwards in essentially the same direction as sunlight, illuminating only the upward-facing side of the leaves and fruit, leaving the fruit's downward-facing (shaded) side with insufficient light. This results in many fruits being unevenly colored, with one side red and the other green. Other grow lights are placed on the ground and shine upwards, but due to potential mud and water seepage from the ground, the fixtures require high-standard protective structures, leading to higher prices, limited practical application, and a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a low-cost, high-efficiency supplemental lighting for fruit and vegetable plants.

[0004] This utility model is achieved through the following technical solution:

[0005] A supplemental light for fruit and vegetable plants includes a lamp head, the lower part of which is connected to a transparent diffuser. An aluminum-based circuit board is installed inside the diffuser, and the top of the aluminum-based circuit board is provided with several upward-emitting LED beads.

[0006] Furthermore, the lamp holder is an E27 screw-type lamp holder.

[0007] Furthermore, the diffuser is arranged in an inverted funnel shape with the small opening facing upwards.

[0008] Furthermore, the LED beads include red LED beads, blue LED beads and ultraviolet LED beads, and the number of blue LED beads and ultraviolet LED beads is greater than the number of red LED beads.

[0009] Furthermore, the ultraviolet LED beads and blue LED beads are evenly distributed in a ring shape on the aluminum-based circuit board.

[0010] Furthermore, the bottom of the diffuser is provided with an aluminum heat sink for mounting the aluminum-based circuit board.

[0011] Furthermore, the aluminum heat sink is arranged in a tower shape, and the aluminum-based circuit board is located on top of the aluminum heat sink.

[0012] Furthermore, both the outer side of the aluminum heat sink and the diffuser cover are provided with several corresponding screw mounting holes.

[0013] Furthermore, the top of the aluminum heat sink is provided with several positioning and mounting posts, and the aluminum base circuit board is provided with positioning and mounting holes corresponding to the positioning and mounting posts.

[0014] Furthermore, the diffuser is a PC diffuser, and a driving power supply that is electrically connected to the lamp head and the aluminum-based circuit board is installed inside the diffuser.

[0015] Compared to existing technologies, this invention features a transparent diffuser connected to the lower part of the lamp head, and several upward-emitting LED beads on the top of the aluminum-based circuit board. In use, the supplemental lighting for fruit and vegetable plants can be suspended below the fruit trees, with the light source pointing towards the lamp head, illuminating upwards. The light reaches the bottom of the fruit, ensuring ample illumination on the side facing away from the ground, resulting in a uniform red color on both the top and bottom surfaces. This invention revolutionizes the application of traditional plant growth lighting in the field of supplemental lighting. Furthermore, the suspended design avoids the risk of waterlogging associated with placing the lighting on the ground. The low-cost protective structure and affordable price of this supplemental lighting make it a practical and user-friendly solution. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 This utility model discloses a supplemental lighting fixture for fruit and vegetable plants, comprising a lamp head 1, a transparent diffuser 2 connected to the lower part of the lamp head 1, an aluminum-based circuit board 3 installed inside the diffuser 2, and several upward-emitting LED beads 4 on the top of the aluminum-based circuit board 3. In use, the supplemental lighting fixture can be suspended below the fruit tree, with the light source pointing towards the lamp head, illuminating from bottom to top. The light can reach the bottom of the fruit from bottom to top, ensuring sufficient light on the side of the fruit facing the ground (the side facing away from the light), resulting in a reddish color on both the top and bottom surfaces of the fruit, with uniform color. This invention revolutionizes the application scenario of traditional plant growth lighting in the field of plant supplemental lighting. Furthermore, the suspended design of the supplemental lighting fixture avoids the risk of water damage associated with placing it on the planting ground. The fixture has a low standard of protective structure, is inexpensive, has practical application value, and offers a good user experience.

[0022] As a specific implementation method, lamp holder 1 is an E27 screw-type lamp holder, which is convenient to install and use.

[0023] The diffuser 2 is set in an inverted funnel shape with the small opening facing upwards. After hoisting, the surface of the diffuser 2 is inclined to the horizontal plane with an acute angle, which can drain away the rainwater that falls on the lamp body more quickly.

[0024] The LED light beads 4 include red LED light beads, blue LED light beads, and ultraviolet LED light beads. The number of blue LED light beads and ultraviolet LED light beads is greater than the number of red LED light beads. The product uses a mixture of red, blue, and ultraviolet light beads for light distribution. Red light is the light color most needed for plant photosynthesis and plays a major role in this lamp. However, the color change of fruits depends more on blue and ultraviolet light. Therefore, the biggest feature of this product is that it contains a high proportion of ultraviolet and blue light. The proportion of ultraviolet light quantum flux density ranges from 5% to 40%. This is different from 100% ultraviolet lamps used for sterilization and is also different from other plant growth lamps that have little or no ultraviolet light.

[0025] Ultraviolet LED beads and blue LED beads are evenly distributed in a ring on the aluminum-based circuit board 3. Multiple ultraviolet LED beads and blue LED beads together form a ring and are evenly distributed in the aluminum-based circuit board 3. The purpose is to allow the blue and ultraviolet light to diffuse more evenly from the center to the periphery, and at the same time, it is also a clear visual identification.

[0026] The bottom of the diffuser 2 is provided with an aluminum heat sink 5 for mounting the aluminum-based circuit board 3, which facilitates the installation and heat dissipation of the aluminum-based circuit board 3.

[0027] The aluminum heat sink 5 is arranged in a tower shape, and the aluminum base circuit board 3 is located on the top of the aluminum heat sink 5. The heat sink aluminum plate 5 is divided into three or more steps from bottom to top, and is generally tower-shaped. The aluminum base circuit board 3 is placed on the first step from top to bottom. This step is higher than the screw hole position. The purpose is to prevent water vapor from entering the lamp body and condensing into water droplets, which would soak the circuit of the light source and the lamp beads. Because water flows downhill, after the first step is raised, the water will naturally flow down and will not affect the aluminum base circuit board 3.

[0028] The outer side of the aluminum heat sink 5 and the diffuser 2 are provided with several corresponding screw mounting holes, so that the aluminum heat sink 5 can be installed on the diffuser 2 by screws.

[0029] The top of the aluminum heat sink 5 is provided with several positioning and mounting posts, and the aluminum base circuit board 3 is provided with positioning and mounting holes corresponding to the positioning and mounting posts. The aluminum heat sink 5 is provided with multiple positioning and mounting posts on the second step from the top down. The size of the posts is the same as the round dots of the aluminum base circuit board 3. The two form a concave-convex mating and fit tightly together. The purpose of this design is to prevent the aluminum base circuit board 3 from moving during production or when the product is moved.

[0030] As a specific implementation method, the diffuser 2 is a PC diffuser. PC diffusers have high strength, high transparency, good impact resistance, light weight, are not easily broken, and have good performance.

[0031] The diffuser cover 2 is equipped with a drive power supply 6 that is electrically connected to the lamp head 1 and the aluminum-based circuit board 3 respectively, providing stable and continuous power for the supplemental lighting under the melon and fruit plants.

[0032] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
