Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to an adjustment component for an LED floodlight. Background Technology

[0002] In the field of LED floodlight applications, the structural design of traditional LED floodlights has obvious limitations: their illumination area is usually determined by the fixed angle of the lampshade and the focal length of the lens, and cannot be flexibly adjusted according to the needs of the actual use scenario. When it is necessary to change the illumination coverage, it is often necessary to replace the lamps with different specifications, which is cumbersome and increases costs. At the same time, the number of LED chips used is fixed. Regardless of the size of the illumination area, all LED chips are in working condition. In scenarios where only a small area of ​​lighting is required, the continuous operation of excess LED chips will cause energy waste and does not meet the requirements of energy conservation.

[0003] To address this, an adjustment component for an LED floodlight is proposed. Utility Model Content

[0004] In view of the problems existing in the adjustment components of the above-mentioned LED floodlights, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an adjustment component for an LED floodlight, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustment component for an LED floodlight includes a lamp frame fixedly mounted on a lamp housing. Both sides of the lamp frame are provided with sliding openings, and a first light-shielding plate and a second light-shielding plate are slidably inserted into the interior of the sliding openings on both sides, respectively. The first light-shielding plate and the second light-shielding plate can block the openings of the lamp frame.

[0008] The bottom of the lamp frame is provided with an adjustment mechanism, and the adjustment mechanism is connected to the first light shield and the second light shield;

[0009] The top of the lamp frame is provided with a lamp bead adjustment mechanism that is connected to the first light shield.

[0010] Preferably, the adjustment mechanism includes a fixed cover fixedly disposed at the bottom of the lamp frame, a bidirectional screw is provided inside the fixed cover for horizontal rotation, and two screw seats are symmetrically slidably disposed inside the fixed cover. The two screw seats are threadedly connected to both sides of the rod wall of the bidirectional screw. A connecting rod is fixedly disposed at the top of each of the two screw seats, and the upper ends of the two connecting rods are respectively fixedly connected to the bottom of the first light shield and the bottom of the second light shield.

[0011] Preferably, the bottom of the lamp frame has a strip-shaped opening, both of the connecting rods pass through the inside of the strip-shaped opening, and one end of the screw extends to the outside of the fixing cover and is fixedly provided with a knob.

[0012] Preferably, the lamp bead adjustment and resistance mechanism includes a slider fixedly disposed on the top of the first light shield, a conductive sleeve fixedly disposed inside the slider, a strip groove is formed on the top inner wall of the lamp frame, and a resistance rod is fixedly disposed inside the strip groove, the resistance rod being slidably connected to the conductive sleeve.

[0013] Furthermore, the slider is made of PTFE insulation.

[0014] Preferably, both the first and second light-shielding plates are made of opaque PC sheets.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model, through the first and second light-shielding plates slidably arranged in the sliding openings on both sides of the lamp frame, together with the adjustment mechanism at the bottom, can flexibly change the blocking area of ​​the lamp frame opening, realize the precise adjustment of the illumination area, and adapt to the lighting needs of different scenarios without replacing the lamp, thus improving the versatility and ease of use of the lamp.

[0017] 2. This utility model uses a slider to drive the conductive sleeve to slide on the resistor rod, which can synchronously adjust the circuit resistance as the first light-shielding plate moves, thereby realizing the linkage control of the number of working lamp beads or the brightness.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-3 The adjustable component of the LED floodlight shown includes a lamp frame 1 fixedly mounted on the lamp housing. Both sides of the lamp frame 1 are provided with sliding openings, and a first light-shielding plate 2 and a second light-shielding plate 3 are slidably inserted into the interior of the sliding openings on both sides. The first light-shielding plate 2 and the second light-shielding plate 3 can block the openings of the lamp frame 1. Both the first light-shielding plate 2 and the second light-shielding plate 3 are made of PC opaque board to ensure stable light-shielding effect and adapt to the temperature environment when the lamp is working.

[0026] The bottom of the lamp frame 1 is provided with an adjustment mechanism, which is connected to the first light shield 2 and the second light shield 3. The adjustment mechanism includes a fixed cover 4 fixedly installed at the bottom of the lamp frame 1. A bidirectional screw 5 is provided inside the fixed cover 4 for horizontal rotation. Two screw seats 6 are symmetrically slidable inside the fixed cover 4. The two screw seats 6 are threadedly connected to both sides of the rod wall of the bidirectional screw 5. A connecting rod 7 is fixedly installed on the top of each screw seat 6. The upper ends of the two connecting rods 7 are fixedly connected to the bottom of the first light shield 2 and the bottom of the second light shield 3, respectively. A strip-shaped opening 8 is opened at the bottom of the lamp frame 1. The two connecting rods 7 are inserted into the inside of the strip-shaped opening 8. One end of the screw 5 extends to the outside of the fixed cover 4 and is fixedly provided with a knob 9. Rotating the knob 9 drives the bidirectional screw 5 inside to rotate. When the bidirectional screw 5 rotates, the two screw seats 6 threadedly connected to both sides of its rod wall slide symmetrically along the inside of the fixed cover 4. The connecting rod 7 at the top of the screw seat 6 passes through the strip-shaped opening 8 at the bottom of the lamp frame 1, respectively driving the first light shield 2 and the second light shield 3 to slide in the sliding openings on both sides of the lamp frame 1.

[0027] The top of the lamp frame 1 is provided with a lamp bead adjustment mechanism connected to the first light shield 2. The lamp bead adjustment mechanism includes a slider 10 fixedly installed on the top of the first light shield 2. A conductive sleeve 11 is fixedly installed inside the slider 10. A strip groove 12 is opened on the inner wall of the top of the lamp frame 1, and a resistance rod 13 is fixedly installed inside the strip groove 12. The resistance rod 13 is slidably connected to the conductive sleeve 11. The slider 10 is made of PTFE insulating block to prevent leakage of conductive parts and ensure safe use. The conductive sleeve 11 moves on the resistance rod 13, which can change the current connected to the resistance rod 13 in the lamp circuit. The measuring circuit of the resistance rod 13 is electrically connected to the lamp circuit. The control system inside the lamp controls the number or brightness of the lamp beads according to the change in the current of the resistance rod 13.

[0028] Working principle: When the illumination area needs to be changed, the operator turns the knob 9 on the outside of the fixed cover 4, which drives the internal double-sided screw 5 to rotate. When the double-sided screw 5 rotates, the two screw seats 6 connected by threads on both sides of its rod wall slide symmetrically along the inside of the fixed cover 4. The connecting rod 7 at the top of the screw seat 6 passes through the strip opening 8 at the bottom of the lamp frame 1, and drives the first light shield 2 and the second light shield 3 to slide in the sliding openings on both sides of the lamp frame 1. When the first light shield 2 and the second light shield 3 are close to each other, the area of ​​the opening of the lamp frame 1 that is blocked increases and the illumination area decreases. When the two are far apart, the blocking area decreases and the illumination area increases, thereby realizing the flexible adjustment of the illumination area.

[0029] Simultaneously, during the sliding process of the first light-shielding plate 2, the slider 10 at its top moves along with it. The conductive sleeve 11 inside the slider 10 slides on the resistor rod 13 in the strip groove 12 on the inner wall of the top of the lamp frame 1. By changing the contact position between the conductive sleeve 11 and the resistor rod 13, the resistance in the circuit is adjusted, thereby controlling the number of working lamps or the brightness. When the irradiation area shrinks, the resistance change causes some lamps to stop working or reduce their brightness, avoiding energy waste. When the irradiation area expands, the resistance adjustment causes more lamps to work or increases the brightness, ensuring the lighting effect.

[0030] Among them, the slider 10 uses a PTFE insulating block to prevent leakage of conductive parts and ensure safe use. The first light-shielding plate 2 and the second light-shielding plate 3 use PC opaque plates to ensure stable light-shielding effect and adapt to the temperature environment when the lamp is working. Through the linkage between the adjustment mechanism and the lamp bead adjustment variable resistance mechanism, the irradiation area and the working state of the lamp bead are coordinated and adjusted, which improves the applicability and energy saving of the LED floodlight.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
