Description

Technical Field

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

[0002] Energy-saving LED lamps refer to lamps that use light-emitting diodes (LEDs) as light sources. They have the characteristics of high efficiency, low energy consumption, and long life. Generally, LED lamps have very low power consumption. Generally speaking, their operating voltage is 2-3.6V, the operating current is 0.02-0.03A, and the power consumption does not exceed 0.1W. Therefore, they have good energy-saving effects. Therefore, in order to reduce energy consumption and lower lighting costs, people currently use this type of LED ceiling lamp when choosing ceiling lamps, which can take into account brightness while reducing energy consumption.

[0003] However, in order to enhance the reflection effect, reduce glare, and further increase its brightness, the above-mentioned LED ceiling lamp will set a circle of reflectors around the bulb. The reflective material on the inner wall of the reflector will reflect the light emitted by the LED lamp to the required place, thereby enhancing the lighting brightness of the target area and avoiding light scattering and waste. However, when using common reflectors, it is found that since the angle between the reflector and the bulb is usually fixed, when the user wants to experience different lighting effects according to his or her own needs, this fixed-angle reflector has great limitations and may need to be replaced by a lamp. It is not flexible enough to use and difficult to meet various needs.

A second reflector 3 and a third reflector 4 are threadedly installed at the bottom of the connecting seat 1. This threaded installation method is achieved by opening two annular grooves at the bottom of the connecting seat 1, with the inner walls of the two annular grooves being threaded, and a part of the tops of the second reflector 3 and the third reflector 4 also being threaded. Thus, the second reflector 3 and the third reflector 4 can be screwed into the two annular grooves to form a threaded installation. And the second reflector 3 is located between the first reflector 2 and the third reflector 4. A positioning seat 5 is provided above the connecting seat 1. An LED bulb 6 is provided inside the third reflector 4. The angle between the first reflector 2 and the LED bulb 6 is greater than the angle between the second reflector 3 and the LED bulb 6, and the angle between the second reflector 3 and the LED bulb 6 is greater than the angle between the third reflector 4 and the LED bulb 6, so as to provide different emission effects for users to choose from. The top of the provided LED bulb 6 penetrates through the connecting seat 1 and is threadedly connected to the positioning seat 5. This connection method is one of the common connection methods for LED bulbs 6, and it only needs to be installed and removed by screwing, which is convenient for disassembly and replacement. And the LED bulb 6 is movably connected to the connecting seat 1. Titanium dioxide coatings 7 are coated on the inner walls of the first reflector 2, the second reflector 3, and the third reflector 4.

The power supply system thereof will not be elaborated here too much, and finished products can be purchased on the market for use.

[0021] In the above - mentioned method, in order to achieve a good heat - dissipation effect during the lighting process and reduce the adverse effects of high temperature on the reflector, a first annular inner cavity 9, a second annular inner cavity 10, and a third annular inner cavity 11 are provided in the connecting seat 1.

The bottom ends of the plurality of air - jet nozzles 12 extend below the connecting seat 1. Moreover, a plurality of ventilation holes 8 distributed in a circular - array are provided on the first reflector 2, the second reflector 3, and the third reflector 4. The ventilation holes 8 are located at the lower part of the first reflector 2, the second reflector 3, and the third reflector 4. In addition, a micro - blower 13 is fixedly installed on the top of the positioning seat 5, and a ventilation pipe 14 is fixedly installed on its air - outlet port. One end of the ventilation pipe 14 is fixedly connected to the positioning seat 5, the other end is sealed, and three electric control valves are fixedly installed at the bottom of the ventilation pipe 14. A first air - duct 15, a second air - duct 16, and a third air - duct 17 are fixedly installed on the connecting seat 1. The tops of the first air - duct 15, the second air - duct 16, and the third air - duct 17 are respectively connected to the ports of the three electric control valves through flange plates. The flange plates are connected by bolts, which facilitates the disassembly between the first air - duct 15, the second air - duct 16, the third air - duct 17 and the electric control valves. And the bottom end of the first air - duct 15 extends into the first annular inner cavity 9, the bottom end of the second air - duct 16 extends into the second annular inner cavity 10, and the bottom end of the third air - duct 17 extends into the third annular inner cavity 11. In this way, by starting the micro - blower 13, the air circulation inside the reflector can be accelerated, thereby improving the heat - dissipation capacity.

[0022] In this method, in order to facilitate the disassembly and assembly between the connecting seat 1 and the positioning seat 5, two vertical buckling grooves 19 are formed at the bottom of the positioning seat 5. Buckling blocks 20 are arranged in both of the two vertical buckling grooves 19. The bottoms of the two buckling blocks 20 are fixedly connected to the connecting seat 1. Horizontal embedding grooves 21 are formed on one side of each of the two buckling blocks 20. Two sinking grooves 22 are formed on one side of the positioning seat 5. Positioning rods 23 are arranged in both of the two sinking grooves 22. One ends of the two positioning rods 23 respectively extend out of the two sinking grooves 22, and the other ends of the two positioning rods 23 respectively extend into the two horizontal embedding grooves 21. Both of the two positioning rods 23 are slidably connected to the inner walls of the corresponding sinking grooves 22 close to the vertical buckling grooves 19. Moreover, connecting pieces 24 are fixedly sleeved on both of the two positioning rods 23. The two connecting pieces 24 are respectively located in the two sinking grooves 22. First return springs 25 are sleeved on both of the two positioning rods 23. One ends of the two first return springs 25 are respectively fixedly connected to the two connecting pieces 24, and the other ends of the two first return springs 25 are respectively fixedly connected to the inner walls of the two sinking grooves 22 close to the vertical buckling grooves 19. Adaptor ball heads 26 are fixedly installed at the ends of the two positioning rods 23 located outside the sinking grooves 22. A connecting folding strip 27 is fixedly installed at the top of the positioning seat 5. A first screw rod 28 is threadedly installed on the connecting folding strip 27. The bottom end of the first screw rod 28 is rotatably installed with a first trapezoidal wedge block 29. The first trapezoidal wedge block 29 abuts against the two adaptor ball heads 26. By means of the abutment between the two, the positioning rods 23 can be firmly inserted into the horizontal embedding grooves 21, so as to ensure the stability when the connecting seat 1 and the positioning seat 5 are installed; When it is necessary to disassemble the connecting seat 1 and the positioning seat 5, only need to rotate the first screw rod 28, gradually remove the abutting force of the first trapezoidal wedge block 29 on the adaptor ball head 26, and then the positioning rods 23 can be taken out of the horizontal embedding grooves 21, so that the connecting seat 1 and the positioning seat 5 can be disassembled.

[0023] In this embodiment Under normal use, it is installed on the top inside the house through the suction top plate 18, so as to achieve the ceiling suction effect. And in the initial state, all three electromagnetic control valves are in the closed state, and the two first return springs 25 arranged are in the stretched state; During the lighting process, the third reflector 4 can reflect the light beam emitted by the LED lamp 6 in a directional manner to the place where it is needed. Moreover, the titanium dioxide coating 7 can effectively scatter and reflect infrared rays, so as to improve the light output rate and light efficiency of the LED lamp 6. At the same time, it can also enhance the color rendering property of the LED lamp 6 and reduce glare, providing a more uniform and soft lighting effect; During the use process, in order to prevent the heat emitted during the illumination of the LED bulb from being too high and affecting the light transmission performance and optical performance of the third reflector 4, the electric control valve corresponding to the third air duct 17 can be opened first, and then the micro blower 13 is started. The micro blower 13 will extract air to form an air flow, and then send these air flows into the ventilation pipe 14, and then enter the third air duct 17 through the opened electric control valve, and then enter the third annular inner cavity 11, and finally spray out through the corresponding plurality of air nozzles 12, so as to be able to accelerate the air circulation inside the third reflector 4. At the same time, with the cooperation of the ventilation holes 8, a strong cooling effect is formed, effectively ensuring the normal reflection work of the third reflector 4; In subsequent use, when it is necessary to use different reflectors to reflect the light beam emitted by the LED bulb 6, the third reflector 4 can be screwed out. At this time, the reflector corresponding to the LED bulb 6 is the second reflector 3, so as to be able to form different reflection effects with the third reflector 4. Correspondingly, the electric control valve corresponding to the third reflector 4 and the electric control valve corresponding to the second reflector 3 are both opened, so as to continue to form an effect of accelerating cooling; Similarly, when it is necessary to use the first reflector 2 to form different reflection effects, the second reflector 3 and the third reflector 4 can be screwed out at the same time, and the three electric control valves can be opened at the same time. The operation is simple and easy to operate; In subsequent use, when it is necessary to remove the connection seat 1 from the positioning seat 5, the LED bulb 6 can be screwed out first, and then the flanges between the first air duct 15, the second air duct 16 and the third air duct 17 and the three electric control valves are disassembled. Subsequently, the first screw rod 28 is rotated counterclockwise, and the first trapezoidal wedge block 29 will rise. At this time, the stretched first return spring 25 will gradually pull back, and finally the two clamping rods 23 will respectively move out of the corresponding horizontal clamping grooves 21, and then the buckling block 20 on the connection seat 1 can be directly pulled out of the vertical buckling groove 19 to achieve disassembly.

[0024] Compared with the related technology, the reflector structure of the energy-saving LED lamp provided by the present invention has the following beneficial effects: First, by setting the first reflector 2, the second reflector 3 and the third reflector 4 with different angles with respect to the LED bulb 6, the present invention can be selected and used according to actual needs, increasing the flexibility of reflection, improving the multi-faceted use experience of users, and the titanium dioxide coating 7 provided on the inner walls of the three reflectors can improve the reflectivity and scattering ability; Second, by setting the first annular inner cavity 9, the second annular inner cavity 10 and the third annular inner cavity 11, as well as the air nozzles 12 for air outlet, the present invention can accelerate the cooling speed and effect during the illumination of the LED bulb 6, thereby providing cooling guarantee for the first reflector 2, the second reflector 3 and the third reflector 4 during the use process and ensuring the reflection effect; III. By providing the vertical fastening grooves 19 and fastening blocks 20, and the insertion connection between the positioning rods 23 and the transverse insertion grooves 21, the connection seat 1 can be conveniently removed from the positioning seat 5, thus facilitating disassembly and assembly by the user.

[0025] Second Embodiment: Based on the reflector structure of the energy-saving LED lamp provided in the first embodiment of the present application, the second embodiment of the present application proposes another reflector structure of the energy-saving LED lamp. The second embodiment is merely a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0026] The following further describes the second embodiment of the present invention in conjunction with the drawings and embodiments.

[0027] Please refer to Figures 11 - 16 , the reflector structure of the energy-saving LED lamp further includes a color-changing plate 30. The color-changing plate 30 is attached to the bottoms of the first reflector 2, the second reflector 3, and the third reflector 4, and the color-changing plate 30 can change the color of the light beam emitted by the LED bulb 6, thereby increasing the diversity of reflected colors. A bearing panel 31 is fixedly installed on the outer wall of the connection seat 1, and a first cross platform 32 is fixedly installed on the side away from the connection seat 1. A through hole is opened on the first cross platform 32. A plugging post 33 is fixedly installed on the top of the color-changing plate 30. The plugging post 33 passes through the through hole and contacts the inner wall of the through hole. Slots 35 are opened on both sides of the plugging post 33. Two vertical plates 36 are fixedly installed on the top of the first cross platform 32. Slide columns 37 are slidably installed on both of the two vertical plates 36. The ends of the two slide columns 37 close to each other are spherical surfaces, and the two spherical surfaces respectively extend into the two slots 35. Sleeve rings 38 are fixedly sleeved on both of the two slide columns 37. Second return springs 39 are sleeved on both of the two slide columns 37. The ends of the two second return springs 39 away from each other are respectively fixedly connected to the two vertical plates 36, and the ends of the two second return springs 39 close to each other are respectively fixedly connected to the two sleeve rings 38. Moreover, in order to ensure the horizontal correspondence between the slot 35 and the slide column 37, a limiting spacer 34 is fixedly sleeved on the plugging post 33, and the top of the limiting spacer 34 contacts the bottom of the first cross platform 32. By using the generated limiting effect, the horizontal correspondence between the slot 35 and the slide column 37 can be ensured.

[0028] In this method, in order to make the slide post 37 tightly inserted in the slot 35, a second trapezoidal wedge 40 is fixedly installed on the end of the two slide posts 37 away from each other, and a second cross platform 41 is fixedly installed on the side of the load-bearing panel 31 away from the connecting seat 1, on which a second screw rod 42 is threadedly installed, and a lower pressure ring cover 43 is rotatably installed at the bottom end of the second screw rod 42, and a limiting rod is slidably installed on the second cross platform 41, and the bottom end of the limiting rod is fixedly connected to the lower pressure ring cover 43, so as to ensure that the lower pressure ring cover 43 can only perform linear lifting movement, and the bottom inner edge of the lower pressure ring cover 43 set above is set as an inclined sliding surface, which conflicts with the second trapezoidal wedge 40, thereby ensuring that the slide post 37 is tightly inserted in the slot 35.

[0029] In this embodiment In the initial state, the second return spring 39 is in a stretched state, and a plurality of color-changing plates 30 can be prepared in advance, each color-changing plate 30 has a different color, and each color-changing plate 30 is provided with an inserting column 33; During use, when the light beam of the LED bulb 6 passes through the color-changing plate 30, it can illuminate the specified color, thereby increasing the diversity of light colors reflected by the three reflective covers. In subsequent use, when it is necessary to replace other color-changing plates 30, it is only necessary to rotate the second screw rod 42 counterclockwise, which will lift the lower pressure ring cover 43. During the rise, the resistance force of the inner edge of the bottom of the lower pressure ring cover 43 on the second trapezoidal wedge 40 gradually decreases, thereby gradually pulling back the two second return springs 39, and finally moving the two sliding posts 37 out of the corresponding slots 35, and then directly pulling the fixed post 33 out of the first horizontal platform 32. Then, take out the color-changing plate 30 of the corresponding color, insert the fixing column 33 on it into the through-hole on the first horizontal platform 32 until the limiting spacer 34 contacts the bottom of the first horizontal platform 32, and then rotate the second screw rod 42 clockwise, and the lower pressure ring cover 43 begins to descend, thereby squeezing the two second trapezoidal wedge blocks 40, so that the two second trapezoidal wedge blocks 40 are close to each other, and finally the two sliding columns 37 are inserted into the corresponding slots 35, thereby completing the replacement of the color-changing plate 30.
