Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to a controllable lighting energy-saving LED lamp. Background Art

[0002] The basic structure of an LED is a semiconductor material chip that emits light when electrified. It is cured onto a bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wire or gold wire, and then it is sealed with epoxy resin around to protect the internal core wire. Finally, the outer shell is installed. Therefore, the LED lamp has good seismic performance, and the fields where it can be applied involve daily household appliances such as mobile phones, table lamps, and home appliances, as well as mechanical production.

[0003] When the existing LED lamps are in use, due to the fixed structure of their lamp shades, when it is necessary to change the illumination range, it is necessary to move the position of the LED lamp, or some LED lamps make the lamp post with deformable materials. Therefore, when changing the illumination range, the angle of the LED lamp can be adjusted by twisting the deformable lamp post, but both require manual adjustment, which is rather troublesome. In addition, when it is necessary to increase the intensity of the light, the input intensity of the current is increased, thus increasing the power consumption and having a poor energy-saving effect.

[0004] Based on this, we propose a controllable lighting energy-saving LED lamp. Summary of the Invention

[0011] The light intensity control mechanism further includes a rifled rod rotatably connected to the lower end of the lamp holder. The side wall of the rifled rod is threadedly connected to the mounting seat and also threadedly connected to the driving seat.

[0012] A limiting mechanism is installed in the sliding groove. The limiting mechanism includes a groove opened on the inner wall of the sliding groove. A magnetic column is slidably connected to the inner wall of the groove. A clamping groove cooperating with the magnetic column is opened on the side wall of the slider. A spring is fixedly connected between the magnetic column and the inner wall of the groove.

[0013] The limiting mechanism further includes an electromagnet fixedly connected to the inner wall of the groove. By setting the above mechanisms, the light intensity can be adjusted as needed or kept unchanged while changing the illumination range.

[0014] Another output of the biaxial motor is fixedly connected with a plurality of fan blades, and an arc-shaped conductive block is fixedly connected to the side wall of one of the fan blades.

[0015] A cleaning mechanism is installed on the mounting seat. The cleaning mechanism includes two electric push rods and an arc-shaped conductive plate. The movable end of the electric push rod is fixedly connected with a cleaning block. The inner wall of the cleaning block is attached to the surface of the LED light strip. The arc-shaped conductive plate, the arc-shaped conductive block and the electric push rod are electrically connected.

[0016] Preferably, a plurality of vertical grooves are opened on the inner wall of the installation groove, and worms are rotatably connected to the inner walls of the plurality of vertical grooves.

[0017] Preferably, a mounting plate is fixedly connected to the inner wall of the mounting ring, and a biaxial motor is fixedly connected to the upper end of the mounting plate.

[0018] Preferably, a limiting rod is fixedly connected to the inner wall of the sliding groove, and the side wall of the limiting rod is slidably connected to the slider.

[0019] Preferably, a control switch is arranged at the upper end of the lamp holder. The electromagnet, the control switch and the external power supply are electrically connected through wires.

[0020] Preferably, a damping pad is arranged between the vertical rod and the driving seat, so that the pressure exerted by the slider on the driving seat is less than the friction force between the vertical rod and the driving seat.

[0021] Preferably, a plurality of heat dissipation holes are opened on the inner wall of the installation groove.

[0022] Preferably, both electric push rods are fixedly connected to the side wall of the mounting seat through brackets, and the arc-shaped conductive plate is fixedly connected to the inner wall of the mounting ring.

[0023] Preferably, the arc-shaped conductive plate, the arc-shaped conductive block, the electric push rod and the external power supply are electrically connected via a wire.

[0024] Preferably, the cleaning block is in an M shape and is made of a transparent light-transmitting material.

[0025] The present invention has the following beneficial effects:

[0026] 1. By setting the range adjustment mechanism and driving the condenser plate and the foldable condenser plate to close and stretch, the lighting range of the LED light strip can be quickly adjusted without adjusting the position or angle of the entire lamp, making it more convenient to use;

[0027] 2. By setting up a light intensity control mechanism, when the focusing plate is folded or stretched, the light will also be gathered or dispersed, and the light intensity will change accordingly. By quickly adjusting the height of the mounting base, the focusing plate can automatically adjust the light intensity to keep it constant whether it is folded or stretched;

[0028] 3. By setting the limit mechanism, when the light intensity needs to be changed, just disconnect the control switch, then the electromagnet will be powered off and lose its magnetism, and then the magnetic column will be out of the slot under the action of the spring. At this time, no matter whether the focusing plate is folded or unfolded, the driving rod will make the slider slide on the inner wall of the slide slot, and the driving seat will not move, and then the mounting seat will not move, so that the height of the LED light strip remains unchanged, and then the light intensity will change;

[0029] 4. By setting up a heat dissipation mechanism, when in use, the output shaft at the lower end of the dual-axis motor can be driven to rotate, driving multiple fan blades to rotate, so that the air inside the condenser plate enters the installation groove through the heat dissipation holes, and then the air flows upward through the middle of the installation ring, and finally discharged through the outlet above the lamp holder, thereby accelerating the air circulation inside the condenser plate and playing a heat dissipation role;

[0030] 5. Since the fan blades rotate to suck air for heat dissipation, the acceleration of air circulation will cause more dust in the air to enter the internal space surrounded by the concentrator, and then the surface of the concentrator will gather dust faster. Therefore, an adjustable heat dissipation method is adopted. When the heat dissipation demand is low, the air circulation speed is slow, and when the heat dissipation demand is high, the air circulation speed is fast, which can reduce the entry of dust, thereby reducing the number of cleaning times of the concentrator, saving time and effort;

[0031] 6. By setting up a cleaning mechanism, when the fan blade rotates, it will synchronously drive the arc-shaped conductive block to rotate. When the arc-shaped conductive block rotates to contact the arc-shaped conductive plate, the electric push rod will be powered on and extended, driving the cleaning block to move. When the arc-shaped conductive block separates from the arc-shaped conductive plate, the electric push rod will be powered off and retracted to reset, thereby driving the cleaning block to reset, so that the cleaning block can move back and forth to scrape off the dust adhering to the LED light strip, avoiding dust from blocking the light of the LED light strip and reducing the light intensity.

[0039] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] Referring to Figure 1 - Figure 6 , a controllable lighting energy-saving LED lamp, comprising a lamp base 1 and an LED light strip 2;

[0041] A range adjustment mechanism, as Figure 2 shown, the range adjustment mechanism includes a plurality of mounting rods 3 rotatably connected to the side wall of the lamp base 1. A plurality of condenser plates 4 are fixedly connected to the side walls of the plurality of mounting rods 3, and a foldable condenser plate 5 is fixedly connected between the plurality of condenser plates 4. An installation groove 6 is opened at the upper end of the lamp base 1, and a plurality of vertical grooves 7 are opened on the inner wall of the installation groove 6. A worm 8 is rotatably connected to the inner walls of the plurality of vertical grooves 7. A worm gear 9 is fixedly connected to the side wall of the mounting rod 3. The worm 8 is meshed with the worm gear 9. An installation ring 10 is hermetically slidably connected to the inner wall of the installation groove 6. A mounting plate 11 is fixedly connected to the inner wall of the installation ring 10. A biaxial motor 12 is fixedly connected to the upper end of the mounting plate 11. One output end of the biaxial motor 12 is fixedly connected to a first gear 13. A second gear 14 is fixedly connected to the side wall of the worm 8. The first gear 13 is meshed with the second gear 14.

[0042] Further, when it is necessary to change the illumination range, the output shaft at the upper end of the biaxial motor 12 can be driven to rotate, driving the first gear 13 to rotate, and then driving the second gear 14 to rotate, driving the worm 8 to rotate, thereby driving the worm gear 9 to rotate, driving the mounting rod 3 to rotate, and then driving the condenser plate 4 to rotate. When the condenser plate 4 rotates inward and folds up, the foldable condenser plate 5 will also fold up. At this time, the light of the LED light strip 2 will follow the folding of the condenser plate 4, thereby reducing the illumination range. On the contrary, if the condenser plate 4 rotates outward and unfolds, the foldable condenser plate 5 will also unfold. At this time, the light of the LED light strip 2 will also unfold with the condenser plate 4, increasing the illumination range, so that the illumination range can be quickly adjusted and it is more convenient to use.

[0043] As Figure 2 shown, a plurality of vertical rods 15 are fixedly connected to the lower end of the installation ring 10. The lower ends of the plurality of vertical rods 15 penetrate through the lower end of the lamp base 1 and are fixedly connected to an installation seat 16 together. The LED light strip 2 is fixedly connected to the lower end of the installation seat 16.

[0044] A light intensity control mechanism is installed on the vertical rod 15, and the light intensity control mechanism includes a driving seat 18 slidably connected to the side wall of the vertical rod 15, a plurality of sliding grooves 19 are opened on the upper end of the driving seat 18, and a slider 21 is slidably connected to the inner walls of the plurality of sliding grooves 19, a limit rod 20 is fixedly connected to the inner wall of the sliding groove 19, and the side wall of the limit rod 20 is slidably connected to the slider 21, and the side wall of the focusing plate 4 is rotatably connected to the driving rod 22, and the other end of the driving rod 22 is rotatably connected to the upper end of the slider 21.

[0045] It should be noted that a damping pad is arranged between the vertical rod 15 and the driving seat 18, which can increase the friction between the vertical rod 15 and the driving seat 18. Therefore, when the slider 21 slides back and forth on the inner wall of the slide groove 19 under the action of the driving rod 22, the pressure applied by the slider 21 to the driving seat 18 will be smaller than the friction between the vertical rod 15 and the driving seat 18, and the driving seat 18 can remain stationary at this time.

[0046] The light intensity control mechanism also includes a rifle rod 17 rotatably connected to the lower end of the lamp holder 1 , the side wall of the rifle rod 17 is threadedly connected to the mounting seat 16 , and the side wall of the rifle rod 17 is threadedly connected to the driving seat 18 .

[0047] A limiting mechanism is installed in the slide groove 19, and the limiting mechanism includes a groove 23 opened on the inner wall of the slide groove 19, a magnetic column 24 is slidably connected to the inner wall of the groove 23, a slot 25 cooperating with the magnetic column 24 is opened on the side wall of the slider 21, and a spring 26 is fixedly connected between the magnetic column 24 and the inner wall of the groove 23.

[0048] like Figure 6 As shown, the limiting mechanism also includes an electromagnet 27 fixedly connected to the inner wall of the groove 23, a control switch 28 is provided at the upper end of the lamp holder 1, and the electromagnet 27, the control switch 28 and the external power supply are electrically connected through wires.

[0049] Furthermore, when the focusing plate 4 is retracted to reduce the illumination range, the light will be more concentrated, and the light intensity will increase. If you want to keep the light intensity unchanged when reducing the illumination range, you can press the control switch 28 to close the control switch 28. At this time, the electromagnet 27 will be energized to generate magnetic repulsion, pushing the magnetic column 24 into the slot 25, thereby preventing the slider 21 from sliding in the slot 19. When the focusing plate 4 is retracted, the focusing plate 4 will apply downward pressure to the slider 21 through the driving rod 22, pushing the driving seat 18 to move downward, thereby driving the rifle rod 17 to rotate, so that the mounting seat 16 moves upward. This drives the LED light strip 2 to move upward, increasing the distance between the LED light strip 2 and the table surface, thereby increasing the light divergence distance of the LED light strip 2, which can reduce the light intensity, thereby making the light intensity tend to be constant. On the contrary, when the focusing plate 4 is unfolded, the light will be more divergent, and the light intensity will decrease. At this time, the driving seat 18 will move upward, causing the rifle rod 17 to rotate in the opposite direction, and then the mounting seat 16 will move downward, causing the LED light strip 2 to move downward, reducing the distance from the table surface, and then the light divergence distance of the LED light strip 2 is reduced, which can enhance the light intensity, thereby making the light intensity tend to be constant.

[0050] It is worth mentioning that when the light intensity needs to be changed, it is only necessary to disconnect the control switch 28. At this time, the electromagnet 27 will be powered off and lose its magnetism, and then the magnetic column 24 will be separated from the slot 25 under the action of the spring 26. At this time, no matter whether the focusing plate 4 is folded or unfolded, the driving rod 22 will make the slider 21 slide on the inner wall of the slide groove 19, and the driving seat 18 will not move, and then the mounting seat 16 will not move, so that the height of the LED light strip 2 remains unchanged, and then the light intensity will change.

[0051] A heat dissipation mechanism is installed in the installation groove 6, and the heat dissipation mechanism includes a plurality of heat dissipation holes 29 opened on the inner wall of the installation groove 6. The other output end of the dual-axis motor 12 passes through the lower end of the installation plate 11 and is fixedly connected with a plurality of fan blades 30.

[0052] Furthermore, when in use, the output shaft at the lower end of the dual-axis motor 12 can be driven to rotate, driving the multiple fan blades 30 to rotate, so that the air inside the focusing plate 4 enters the mounting groove 6 through the heat dissipation holes 29, and then the air flows upward through the middle of the mounting ring 10, and finally is discharged through the outlet above the lamp holder 1, thereby accelerating the air circulation inside the focusing plate 4 and playing a heat dissipation role.

[0053] It is worth mentioning that, since the fan blade 30 rotates to suck air for heat dissipation, the accelerated air circulation will cause more dust in the air to enter the internal space surrounded by the condenser plate 4, and then the dust will accumulate on the surface of the condenser plate 4 faster. Therefore, by adopting an adjustable heat dissipation method, the air circulation speed can be slower during low-demand heat dissipation and faster during high-demand heat dissipation, which can reduce the entry of dust, and thus reduce the cleaning frequency of the condenser plate 4, saving time and effort.

[0054] A cleaning mechanism is installed on the mounting seat 16. The cleaning mechanism includes two electric push rods 31 fixedly connected to the side wall of the mounting seat 16 through brackets. The movable end of the electric push rod 31 is fixedly connected with a cleaning block 32, and the inner wall of the cleaning block 32 is arranged in contact with the surface of the LED light bar 2.

[0055] The cleaning mechanism further includes an arc-shaped conductive plate 33 fixedly connected to the inner wall of the mounting ring 10. An arc-shaped conductive block 34 is fixedly connected to the side wall of one of the fan blades 30. The arc-shaped conductive plate 33, the arc-shaped conductive block 34, the electric push rod 31 and an external power supply are electrically connected through wires.

[0056] Furthermore, when the fan blade 30 rotates, it will synchronously drive the arc-shaped conductive block 34 to rotate. When the arc-shaped conductive block 34 rotates to contact the arc-shaped conductive plate 33, the electric push rod 31 will be energized and extended, driving the cleaning block 32 to move. When the arc-shaped conductive block 34 separates from the arc-shaped conductive plate 33, the electric push rod 31 will be powered off and retract to reset, thereby driving the cleaning block 32 to reset, so that the cleaning block 32 can reciprocate to scrape off the dust adhering to the LED light bar 2, preventing the dust from blocking the light of the LED light bar 2 and reducing the light intensity.

[0057] The cleaning block 32 is in an M shape and is made of a transparent light-transmitting material.

[0058] In the present invention, during use, the output shaft at the lower end of the dual-axis motor 12 can be driven to rotate, driving the plurality of fan blades 30 to rotate, so that the air inside the condenser plate 4 enters the mounting groove 6 through the heat dissipation holes 29, and then the air will flow upward through the middle of the mounting ring 10 and finally be discharged from the outlet above the lamp holder 1, thereby accelerating the air circulation inside the condenser plate 4 and playing a role in heat dissipation.

[0059] When the fan blade 30 rotates, it will synchronously drive the arc-shaped conductive block 34 to rotate. When the arc-shaped conductive block 34 rotates to contact the arc-shaped conductive plate 33, the electric push rod 31 will be energized and extended, driving the cleaning block 32 to move. When the arc-shaped conductive block 34 separates from the arc-shaped conductive plate 33, the electric push rod 31 will be powered off and retract to reset, thereby driving the cleaning block 32 to reset, so that the cleaning block 32 can reciprocate to scrape off the dust adhering to the LED light bar 2, preventing the dust from blocking the light of the LED light bar 2 and reducing the light intensity.

[0060] When the illumination range needs to be changed, the output shaft at the upper end of the dual-axis motor 12 can be driven to rotate, driving the first gear 13 to rotate, and then driving the second gear 14 to rotate, driving the worm 8 to rotate, thereby driving the worm wheel 9 to rotate, driving the mounting rod 3 to rotate, and then driving the focusing plate 4 to rotate. When the focusing plate 4 rotates inward and retracts, the foldable focusing plate 5 will be folded and retracted. At this time, the light of the LED light strip 2 will follow the focusing plate 4 to retract, thereby reducing the illumination range. On the contrary, if the focusing plate 4 rotates outward and expands, the foldable focusing plate 5 will also stretch and expand. At this time, the light of the LED light strip 2 will also expand with the focusing plate 4 to increase the illumination range, so that the illumination range can be quickly adjusted, which is more convenient to use.

[0061] When the focusing plate 4 is retracted to reduce the illumination range, the light will be more concentrated, and the light intensity will increase. If you want to keep the light intensity unchanged when reducing the illumination range, you can press the control switch 28 to close the control switch 28. At this time, the electromagnet 27 will be energized to generate magnetic repulsion, pushing the magnetic column 24 into the slot 25, thereby preventing the slider 21 from sliding in the slot 19. When the focusing plate 4 is retracted, the focusing plate 4 will apply downward pressure to the slider 21 through the driving rod 22, pushing the driving seat 18 to move downward, thereby driving the rifle rod 17 to rotate, causing the mounting seat 16 to move upward, driving The LED light strip 2 moves upward, so that the distance between the LED light strip 2 and the table surface increases, and then the light divergence distance of the LED light strip 2 increases, which can reduce the light intensity, and then the light intensity tends to be constant. On the contrary, when the focusing plate 4 is unfolded, the light will diverge more, and the light intensity will decrease. At this time, the driving seat 18 will move upward, causing the rifle rod 17 to rotate in the opposite direction, and then the mounting seat 16 will move downward, causing the LED light strip 2 to move downward, and the distance from the table surface is reduced, and then the light divergence distance of the LED light strip 2 is reduced, which can enhance the light intensity, and then the light intensity tends to be constant.

[0062] When the light intensity needs to be changed, the control switch 28 only needs to be turned off. At this time, the electromagnet 27 will be powered off and lose its magnetism, and then the magnetic column 24 will be separated from the slot 25 under the action of the spring 26. At this time, no matter whether the focusing plate 4 is folded or unfolded, the driving rod 22 will make the slider 21 slide on the inner wall of the slide groove 19, and the driving seat 18 will not move, and then the mounting seat 16 will not move, so that the height of the LED light strip 2 remains unchanged, and then the light intensity will change.

[0063] In addition, when the condenser plate 4 is folded up to concentrate light, the internal space surrounded by the condenser plate 4 will decrease. As a result, the heat generated by the LED light bar 2 will rapidly diffuse in the space, causing the internal temperature to rise faster. Since the mounting base 16 moves upward when the condenser plate 4 is folded up, the mounting base 16 will push the mounting ring 10 upward through the vertical rod 15. At this time, more heat dissipation holes 29 will be exposed, which can increase the air circulation speed and improve the heat dissipation effect.

[0064] Since the air is cooled by the rotation of the fan blade 30 to suck air, the acceleration of air circulation will cause more dust in the air to enter the internal space surrounded by the condenser plate 4. As a result, dust will accumulate on the surface of the condenser plate 4 faster. Therefore, by adopting an adjustable heat dissipation method, the air circulation speed can be slower under low heat dissipation requirements and faster under high heat dissipation requirements, which can reduce the entry of dust, and thus reduce the cleaning frequency of the condenser plate 4, saving more time and effort.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
