Description

Technical Field

[0001] The invention relates to a downlight, in particular to a downlight with adjustable irradiation range. Background Art

[0002] Downlights are widely used in modern decoration. Although some downlights can be rotated to adjust the irradiation angle, the irradiation range of existing downlights is fixed after installation. For some situations where the irradiation range needs to be adjusted, such as the lighting required for exhibits in museums, it is generally achieved by external vertically adjustable brackets. However, this installation structure is relatively complicated, and the power supply lines are exposed, which is not beautiful enough. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a downlight with adjustable irradiation range.

[0004] In order to solve the above technical problems, the technical scheme adopted by the present invention is: a downlight with adjustable illumination range, comprising a cylindrical mounting seat, a limiting ring is provided on the inner periphery of the lower edge of the mounting seat, a mounting positioning ring is provided on the outer periphery of the lower edge of the mounting seat, mounting spring clips are provided on both sides of the outer wall of the mounting seat, a guide tube seat is detachably provided in the mounting seat, an annular boss matching with the limiting ring is provided on the outer wall of the guide tube seat, a mounting support ring is provided on the inner periphery of the lower edge of the guide tube seat, a plurality of annular positioning grooves are provided on the inner wall of the guide tube seat from top to bottom, a lamp seat is movably provided in the guide tube seat, and a lens, a reflector and a lamp board are provided in the lamp seat; a heat dissipation cover is detachably provided on the lamp seat, the bottom edge of the heat dissipation cover presses the lower edge of the lens to fix the lens, a wire hole is provided on the heat dissipation cover for the wires connected to the lamp board to pass through, a circle of annular mounting groove is provided on the outer periphery of the heat dissipation cover, an elastic ring matching with the annular positioning groove is embedded in the mounting groove, a semicircular pull ring is provided on the lower surface of the lamp seat, and the two ends of the pull ring are transitionally matched with the mounting holes on the lamp seat.

[0005] As a preferred solution, the heat dissipation cover is an aluminum heat dissipation cover.

[0006] As a preferred solution, at least one vertical avoidance groove is provided on the wall of the guide tube seat.

[0007] As a preferred solution, the mounting seat is provided with two inverted T-shaped mounting notches for assembling spring clips.

[0008] As a preferred solution, mounting holes are respectively provided on both sides of the mounting seat, and threaded connection holes matching the mounting holes are provided on both sides of the guide tube seat, and anti-slip bolts pass through the mounting holes and are connected to the threaded connection holes.

[0009] The beneficial effects of the present invention are:

[0010] Since the inner wall of the guide tube seat is provided with a plurality of annular positioning grooves from top to bottom, a lamp holder is movably provided in the guide tube seat, and a lens, a reflector, and a lamp board are provided in the lamp holder; a heat dissipation cover is detachably provided on the lamp holder, and an annular mounting groove is provided on the outer periphery of the heat dissipation cover, and an elastic ring matching the annular positioning groove is embedded in the mounting groove, and a semicircular pull ring is provided on the lower surface of the lamp holder, so that the pull ring can push and pull the lamp holder up and down to adjust the lighting range, and the illumination brightness can be slightly increased while the lighting range is reduced. In addition, by pushing the lamp holder upward, the overall glare value of the downlight can be reduced, the adjustment is convenient, and the use effect is good.

[0011] Due to the transition fit between the two ends of the pull ring and the mounting holes on the lamp holder, the pull ring can be rotated to a horizontal position after the position of the lamp holder is adjusted to avoid affecting the lighting effect.

[0012] Since the heat dissipation cover is made of aluminum, heat dissipation can be better achieved.

[0013] Since at least one vertical avoidance notch is provided on the wall of the guide tube base, the deformed portion of the elastic ring can be accommodated, so that the lamp base can be easily adjusted as a whole, and the elastic ring can provide sufficient supporting force after being adjusted into place.
