Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED downlight with adjustable lighting direction. Background Technology

[0002] LED downlights are a common type of lighting device, installed in areas requiring illumination. To accommodate changes in lighting direction, LED downlights are designed to be adjustable. Current methods involve tilting the entire downlight at a specific angle. However, downlights are typically mounted vertically on ceilings or other surfaces to maintain a unified look. Changing the lighting direction by tilting the entire downlight (light-emitting end) relative to the ceiling also alters the overall aesthetic of the environment, failing to meet the requirement of maintaining a consistent design. Summary of the Invention

[0003] This invention provides an adjustable downlight whose light-emitting end direction does not need to be changed when adjusting the lighting direction, solving the problem that existing LED downlights require overall tilting when changing the lighting direction, which causes the exposed end to damage the appearance of the downlight's location.

[0004] The above technical problems are solved by the following technical solution: an LED downlight with adjustable lighting direction, including a locking structure, a lower reflector, and an LED light hinged to the rear end of the lower reflector via a horizontal hinge axis. The LED light includes an LED light source board, a heat sink for heat dissipation of the LED light source board, and an upper reflector fitted onto the LED light source board and connected to the lower end of the heat sink. The upper reflector is connected to the rear end of the lower reflector. The upper end of the lower reflector has a notch to avoid interference with the rotation of the LED light around the horizontal hinge axis. During the rotation of the LED light, the light emitted by the LED light shines into the lower reflector. The locking structure is used to maintain the LED light at the set angle when it rotates to the set angle. In use, the lighting direction is changed by rotating the LED light around the horizontal hinge axis. Existing LED downlights require the entire LED downlight to be tilted when changing the lighting direction. This technical solution can achieve adjustable lighting direction while keeping the exposed decorative end of the LED downlight unchanged.

[0005] Preferably, the system also includes a light shield, with the lower reflector connected to the lower end of the light shield and the upper reflector passing through the upper end of the light shield. The lower end of the heat sink is connected to a connecting lug, which is rotatably connected to the light shield via the horizontal hinge. The upper end of the light shield has a notch to prevent interference with the rotation of the LED lamp around the horizontal hinge. This design more reliably prevents light leakage.

[0006] Preferably, the lower end of the heat sink is connected to a heat dissipation groove fitted onto the side of the light shield away from the notch in the light shield, and the connecting lug is connected to the heat sink through the heat dissipation groove. This improves the heat dissipation effect.

[0007] Preferably, the locking structure includes a braking surface disposed on the connecting lug, a brake bolt threaded onto the sunshade for pressing against the braking surface for braking, and a torsion spring driving the connecting lug to rotate in the direction of pressing against the brake bolt. When angle adjustment is required, the brake bolt is loosened, and the LED light is rotated to the desired position. Then, the brake bolt is rotated to press against the braking surface for braking, and the torsion spring maintains the braking.

[0008] Preferably, the lower end of the sunshade is provided with several hanging holes, and the outer surface of the lower reflector is provided with several hanging hooks. The hanging hooks are correspondingly engaged with the hanging holes to suspend the lower reflector inside the sunshade. This facilitates the connection between the lower reflector and the sunshade.

[0009] Preferably, the LED downlight body further includes a supporting sleeve, and the lower reflector is rotatably connected inside the supporting sleeve. The supporting sleeve is connected to the suspension plate. This allows the lighting direction to be adjusted 360°.

[0010] Preferably, the LED downlight body is provided with an annular decorative panel that covers the LED downlight mounting hole. The upper surface of the annular decorative panel is provided with a limiting sleeve. The annular decorative panel extends into the limiting sleeve to form a hanging flange. The outer surface of the supporting sleeve is provided with an anti-rotation block. The upper surface of the hanging flange is provided with an anti-rotation notch. The anti-rotation block passes through the anti-rotation notch and is suspended on the hanging flange.

[0011] Preferably, the upper surface of the suspension flange is provided with a plurality of reinforcing strips distributed circumferentially along the suspension flange. The reinforcing strips extend circumferentially along the suspension flange, and the anti-rotation notch is formed between adjacent reinforcing strips. The reinforcing strips are connected together with the limiting sleeve, and the limiting sleeve, the annular decorative panel and the reinforcing strips are integrally formed together. The structure has good strength.

[0012] Preferably, the upper surface of the reinforcing strip is provided with a plurality of reinforcing blocks, the reinforcing blocks being connected together with the limiting sleeve, and the reinforcing blocks, reinforcing strip, and limiting sleeve being integrally formed together. This results in good structural strength.

[0013] Preferably, between the two reinforcing strip ends located at both ends of the anti-rotation notch, one reinforcing strip end is flush with the same reinforcing block, and the other reinforcing strip end has a guide slope facing towards the anti-rotation notch defect. This facilitates the assembly of the support sleeve into the limiting sleeve to the set position.

[0014] Preferably, the device also includes a ring-shaped decorative panel, the rear surface of which is provided with a plurality of hanging blocks having hanging steps distributed circumferentially along the ring-shaped decorative panel. In use, the hanging blocks are suspended in the hanging holes via the hanging steps, thereby installing the device in the downlight mounting hole.

[0015] Preferably, the suspension block includes a base section integrally formed with the annular decorative panel and a tail section detachably connected to the base section. The upper end face of the base section has a threaded hole, and the lower end of the tail section has a threaded head. The threaded head is threaded into the threaded hole of the base section, forming the suspension step between the tail section and the base section. Leveling of the LED downlight body can be achieved by rotating the tail section to the depth it is screwed into the base section.

[0016] Preferably, the circumferential surface of the final section is provided with several drag-increasing vertical protrusions distributed along the circumference of the final section. This prevents slippage when the final section is rotated.

[0017] The present invention has the following advantages: the lighting direction is multi-dimensionally adjustable; when the lighting direction is adjusted, the front end of the lamp remains stationary, thus maintaining the appearance position unchanged. Attached Figure Description

[0028] This utility model also includes a supporting jacket 34, a lower reflector 35 rotatably supported on a supporting step inside the supporting jacket, a light shield 36 fitted onto the rear end of the lower reflector, and an LED lamp connected to the rear end of the lower reflector. The LED lamp includes an LED light source board, a heat sink 37 for dissipating heat from the LED light source board, an upper reflector 38 fitted onto the LED light source board and connected to the lower end of the heat sink, and a light-transmitting panel 39 located at the front end of the upper reflector. The upper reflector is connected to the rear end of the lower reflector. The upper surface of the annular decorative panel is provided with a limiting sleeve 40, and the annular decorative panel extends into the limiting sleeve to form a hanging flange 41. The outer surface of the supporting jacket is provided with an anti-rotation block 2, and the upper surface of the hanging flange is provided with an anti-rotation notch 42. The anti-rotation block passes through the anti-rotation notch and is suspended on the hanging flange. The upper surface of the suspension flange is provided with several reinforcing strips 43 distributed circumferentially along the suspension flange.

The lower end of the sunshade is provided with several hanging holes 55, and the outer surface of the lower reflector is provided with several hanging hooks 56. The hanging hooks are locked in the hanging holes one by one to suspend the lower reflector inside the sunshade.
