Abstract
Description
Technical Field
[0001] This utility model relates to the field of eye-protection LED light technology, specifically an eye-protection LED light with adjustable color temperature. Background Technology
[0002] In the existing LED lighting technology field, especially in the design and application of eye-protection LED lights, heat dissipation has always been one of the key factors restricting performance improvement and lifespan extension. Traditional eye-protection LED lights often focus on improving the comfort and energy efficiency of the light source during design, while relatively neglecting the management of heat generated inside the lamp, which has led to a series of technical bottlenecks.
[0003] During operation, eye-protecting LED lights generate a large amount of heat due to the high-efficiency light-emitting characteristics of LED chips. If this heat cannot be dissipated in a timely and effective manner, it will not only cause the LED chip temperature to rise, affecting its luminous efficiency and color stability, but may also accelerate the aging of LED packaging materials and shorten the overall lifespan of the lamp. In addition, excessively high operating temperatures may also cause thermal stress fatigue of circuit components, increasing the risk of circuit failure and posing a potential threat to the electrical safety of users. Utility Model Content
[0004] The purpose of this invention is to provide an eye-protecting LED lamp with adjustable color temperature, in order to solve the problem mentioned in the background art that, during the operation of the eye-protecting LED lamp, due to the high-efficiency light-emitting characteristics of the LED chip, a large amount of heat energy is generated. If this heat energy cannot be dissipated in a timely and effective manner, it will not only cause the LED chip temperature to rise, affecting its luminous efficiency and color stability, but may also accelerate the aging of the LED packaging material and shorten the overall lifespan of the lamp. In addition, excessively high operating temperature may also cause thermal stress fatigue of circuit components, increase the risk of circuit failure, and pose a potential threat to the user's electrical safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an eye-protecting LED lamp with adjustable color temperature, comprising a housing, a main circuit board fixedly installed at the bottom of the housing, a color temperature adjustment circuit board fixedly installed at the center of the top of the main circuit board, a lamp body fixedly installed at the center of the bottom of the housing, the top of the lamp body fixedly connected to the bottom of the main circuit board, a heat-conducting plate one disposed at the top of the housing, heat-conducting rod one fixedly connected to both sides of the bottom of the heat-conducting plate one, the bottom of the heat-conducting rod one fixedly assembled to the top of the main circuit board, heat-conducting plates two fixedly connected to both sides of the heat-conducting plate one, heat-conducting rod two fixedly connected to the side of the heat-conducting plate two away from the heat-conducting plate one, heat-conducting plate three fixedly connected to the side of the heat-conducting rod two away from the heat-conducting plate two, the side of the heat-conducting plate three extending through to the outside of the housing and fixedly connected to a heat sink, a plurality of heat dissipation holes being opened at the top of the heat sink, and heat dissipation fins fixedly connected to one side of the heat sink.
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] This color-temperature adjustable eye-protection LED light utilizes a highly efficient heat conduction path created by incorporating heat-conducting plates 1, 2, 3, 1, and 2 within the housing. This design rapidly transfers heat generated on the main circuit board and color-temperature adjustment circuit board to the outside of the housing, effectively reducing the internal operating temperature of the lamp. The heat dissipation holes and fins on the heat sink further enhance the heat radiation effect. By increasing the heat dissipation area and air convection, the heat dissipation efficiency is improved. The introduction of a miniature fan, through the intake and exhaust pipes within the housing, forms an active cooling structure. The miniature fan accelerates airflow inside and outside the housing, quickly carrying away heat from the heat sink and further enhancing the cooling effect. This active cooling, combined with the passive cooling structure composed of multiple heat-conducting plates, forms a complementary cooling mechanism, ensuring stable heat dissipation performance of the lamp under various operating conditions.

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.
[0014] Please see Figure 1-4 This utility model provides a technical solution: an eye-protecting LED lamp with adjustable color temperature, including a housing 1. A main circuit board 2 is fixedly installed at the bottom of the housing 1. A color temperature adjustment circuit board 3 is fixedly installed at the center of the top of the main circuit board 2. A lamp body 4 is fixedly installed at the center of the bottom of the housing 1. The top of the lamp body 4 is fixedly connected to the bottom of the main circuit board 2. A heat-conducting plate 10 is provided at the top of the housing 1. Heat-conducting rods 11 are fixedly connected to both sides of the bottom of the heat-conducting plate 10. The heat-conducting plate 10 is fixedly assembled to the top of the main circuit board 2. Heat-conducting plates 12 are fixedly connected to both sides of the heat-conducting plate 10. Heat-conducting rod 13 is fixedly connected to the side of heat-conducting plate 12 away from heat-conducting plate 10. Heat-conducting plate 14 is fixedly connected to the side of heat-conducting rod 13 away from heat-conducting plate 12. Heat-conducting plate 14 extends to the outside of the housing 1 and is fixedly connected to a heat sink 15 on the side away from heat-conducting rod 13. Several heat sink holes 16 are opened on the top of the heat sink 15. Heat sink fins 17 are fixedly connected to one side of the heat sink 15.
[0015] A housing 5 is fixedly installed at the center of the top of the housing 1. A miniature exhaust fan 6 is fixedly installed at the center of the top of the housing 5. The housing 5 is connected to the suction pipe 7 through the air inlets opened on both sides of its bottom. The bottom of the suction pipe 7 extends into the interior of the housing 5. The top of the housing 5 is connected to the air outlet pipe 8 on both sides.
[0016] Mounting plates 9 are fixedly connected to both sides of the top of the housing 1.
[0017] Protective pads 18 are fixedly connected to both sides of the bottom of the box 1.
[0018] A color temperature adjustment knob 20 is fixedly installed at the top position of the center of the rear surface of the cabinet 1.
[0019] A ventilation mesh 19 is fixedly installed on one side of the rear surface of the housing 1.
[0020] A control switch 21 is fixedly installed on the other side of the rear surface of the housing 1.
[0021] Working Principle: When the eye-protection LED lamp is powered on, current flows through the main circuit board 2 to power the entire lamp. The color temperature adjustment circuit board 3 receives power from the main circuit board 2 and adjusts the color temperature of the LED lamp according to the setting value of the color temperature adjustment knob 20. Rotating the color temperature adjustment knob 20 changes the resistance of the potentiometer on the circuit board, thereby changing the working current of the LED beads and achieving color temperature adjustment. The lamp body 4 receives current from the color temperature adjustment circuit board 3 and emits light of the corresponding color temperature. When the LED lamp body 4 emits light, it generates heat. This heat is first transferred to the main circuit board 2 through the top of the lamp body 4. The heat on the main circuit board 2 is transferred to the heat conduction plate 10 through the heat conduction rod 11. The heat conduction plate 10 further distributes the heat to the heat conduction plates 12 on both sides. The heat conduction plates 12 transfer the heat to the heat conduction plate 14 through the heat conduction rod 13. The heat-conducting plate 14 is located outside the housing 1 and exchanges heat with the external environment through the heat dissipation plate 15. The heat dissipation holes 16 and heat dissipation fins 17 on the heat dissipation plate 15 increase the heat dissipation area and improve the heat exchange efficiency. At the same time, the micro fan 6 draws in external cold air through the suction pipe 7, passes through the inside of the housing 5, and then discharges hot air through the exhaust pipe 8, forming forced convection and further enhancing the heat dissipation effect.
[0022] In summary, this color-temperature adjustable eye-protection LED lamp, by setting up heat-conducting plates 10, 12, 14, 11, and 13 inside the housing 1, forms an efficient heat conduction path. This design can quickly conduct the heat generated on the main circuit board 2 and the color-temperature adjustment circuit board 3 to the outside of the housing 1, effectively reducing the internal operating temperature of the lamp. The heat dissipation holes 16 and heat dissipation fins 17 on the heat sink 15 further enhance the heat radiation effect. By increasing the heat dissipation area and air convection, the heat dissipation efficiency is improved. The introduction of the micro fan 6, through the air intake pipe 7 and air outlet pipe 8 inside the housing 5, forms an active heat dissipation structure. The micro fan 6 can accelerate the airflow inside and outside the housing 1, quickly carrying away the heat on the heat sink 15, further improving the heat dissipation effect. This active heat dissipation combined with the passive heat dissipation structure composed of multiple heat-conducting plates forms a complementary heat dissipation mechanism, ensuring that the lamp can maintain stable heat dissipation performance under various operating conditions.
