[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-5 As shown, a spectrum-adjustable LED plant lighting lamp includes a housing 1, a sealing cover 2 on the top of the housing 1, a light-transmitting hole 3 through the center of the top of the housing 1, multiple radially movable lamp holders 12 inside the housing 1, LED lamps 14 at the bottom of the lamp holders 12, a switch button 25 electrically connected to the LED lamps 14 on one side of the lamp holders 1, an adjustment mechanism connected to the lamp holders 12 inside the housing 1 for controlling the movement of LED lamps 14 of different colors above the light-transmitting hole 3, and a reflector 24 on the top of the housing 1 to reflect and converge the light emitted by the LED lamps 14, thereby improving the light efficiency; there are five LED lamps 14, namely red light, blue light, yellow light, green light and ultraviolet light;
[0026] The adjustment mechanism includes multiple mounting blocks 5 arranged equidistantly along the circumferential direction at the bottom of the housing 1. A first insertion groove 6 is provided on the top of the mounting block 5. A first insertion block 7 is inserted into the first insertion groove 6. A slider 8 is fixed on one side of the bottom of the first insertion block 7. A slide groove 9 is provided at the bottom of the first insertion groove 6 to slide and connect with the slider 8. A first spring 10 is fixed on one side of the slider 8 and connected to the inner wall of the slide groove 9. Two guide holes are provided on one side of the first insertion block 7. A guide rod 11 connected to the lamp holder 12 is slidably installed inside the guide holes. A second spring 13 is provided on the outer wall of the guide rod 11 and located between the lamp holder 12 and the first insertion block 7.
[0027] An annular plate 17 is fixed to the inner side of the housing 1. Rotary wheel rings 18 are rotatably installed on both the upper and lower sides of the annular plate 17. A triangular top plate 19 is provided on the inner side of the rotary wheel ring 18. An inner groove is integrally provided in the middle of the triangular top plate 19. A fixing rod 16 that cooperates with the triangular top plate 19 is fixed to the top of the first plug block 7. A toggle hole 23 is opened on one side of the outer wall of the housing 1. Multiple labels are provided on the outer side of the rotary wheel ring 18, and the multiple labels correspond one-to-one with multiple LED lights 14.
[0028] According to the above structure, the triangular top plates 19 on the inner sides of the two rotating rings 18 are one and five respectively, used to control the movement of a single LED light 14 above the light-transmitting hole 3 or to control the synchronous movement of multiple LED lights 14 above the light-transmitting hole 3, increasing the practicality of the equipment; the labels are set to distinguish different colored LED lights 14, making it convenient for staff to turn on the corresponding LED lights 14; the triangular top plates 19 on the inner sides of the two rotating rings 18 are one and five respectively, used to control the movement of a single LED light 14 above the light-transmitting hole 3 or to control the synchronous movement of multiple LED lights 14 above the light-transmitting hole 3. Above the light-transmitting hole 3, the practicality of the equipment is greatly increased; by rotating the rotating ring 18, the triangular top plate 19 can push the fixing rod 16, thereby driving the first plug-in block 7 and the lamp holder 12 to move. The lamp holder 12 drives the LED light 14 to move, so that the LED light 14 is moved above the light-transmitting hole 3; there are five LED lights 14, namely red light, blue light, yellow light, green light and ultraviolet light, to meet the needs of plants for different spectra; the first spring 10 provides a restoring force for the movement of the first plug-in block 7; the switch button 25 is opened when it is squeezed, and the LED light 14 lights up.
[0029] like Figures 2-3 As shown, a plum blossom block 4 is provided at the center of the inner bottom of the housing 1. Multiple grooves that cooperate with the LED light 14 are provided at equal intervals along the circumferential direction on the outer surface of the plum blossom block 4. A light-blocking plate 15 is fixed at the bottom of the lamp holder 12 and on one side of the LED light 14. When the switch button 25 moves into the groove and is squeezed, the LED light 14 lights up.
[0030] According to the above structure, when the lamp holder 12 moves to a specific position, the LED light 14 can be embedded in the groove of the plum blossom block 4 to achieve positioning and prevent the lamp holder 12 from shaking; a light-blocking plate 15 is fixed at the bottom of the lamp holder 12 and on one side of the LED light 14, which can effectively prevent the light emitted by adjacent LED lights 14 from interfering with each other and ensure that the light spectrum illuminating the plant is pure.
[0031] like Figures 1-4 As shown, a fan 21 is provided on the top of the sealing cover 2, a heat sink 20 is provided on the top of the lamp holder 12, and heat dissipation holes 22 are provided on the side wall of the housing 1.
[0032] According to the above structure, the fan 21 can accelerate the airflow and exhaust the heat dissipated by the heat sink 20 on the lamp holder 12 to the outside of the lamp through the heat dissipation hole 22, forming a good heat dissipation cycle, effectively reducing the working temperature of the LED lamp 14, extending its service life, and improving luminous efficiency.
[0033] The working principle of this utility model is as follows: When the spectrum needs to be adjusted, the operator can rotate the corresponding rotating ring 18 according to the actual needs through the actuation hole 23 on one side of the outer wall of the housing 1; if only a single LED lamp 14 needs to work, rotate the rotating ring 18 with a triangular top plate 19 on the inner side, the triangular top plate 19 pushes the fixing rod 16, so that the first plug block 7 moves along the slide groove 9, and drives the lamp holder 12 to move through the guide rod 11, so that the required LED lamp 14 is moved above the light-transmitting hole 3; if multiple LED lamps 14 need to work simultaneously, rotate the five triangular top plates 19 on the inner side. The rotating ring 18 enables multiple lamp holders 12 to move synchronously, allowing multiple LED lights 14 to move above the light-transmitting hole 3. At the same time, the operator can accurately select the required LED light according to the label on the outside of the rotating ring 18. During the operation of the lamp, the LED light 14 generates heat, which is transferred to the heat sink 20 on the lamp holder 12. The fan 21 on the top of the sealing cover 2 starts, accelerating the airflow and exhausting the heat dissipated by the heat sink 20 through the heat dissipation hole 22 on the side wall of the housing 1 to the outside of the lamp, forming a good heat dissipation cycle and ensuring that the LED light 14 operates at a suitable temperature.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
