Embodiment Construction
[0021] figure 1 It is a schematic cross-sectional view of the spotlight with adjustable luminous angle according to the first embodiment of the present invention, figure 2 yes figure 1 The three-dimensional exploded view of the spotlight with adjustable beam angle is shown. The spotlight 100 with adjustable light emitting angle includes a lamp head body 20 , a light emitting element 340 and a light distribution element 10 . The lamp body 20 is a cylindrical structure, the top of the lamp body 20 is provided with a slot 201 , and the light-emitting element 340 is disposed at the bottom of the slot 201 . The light distribution element 10 includes a panel 13 and four first lenses 11 and four second lenses 12 arranged at intervals on the panel 13, the first lenses 11 and the second lenses 12 are arranged at intervals in a circular shape, Two sides of each first lens 11 are respectively second lenses 12 . The light distribution element 10 is rotatably connected to the top of t...

The invention discloses a spot lamp with an adjustable light-emitting angle. The spot lamp comprises a lamp holder, a light-emitting element and a light distributing element. A groove is formed in the top of the lamp holder, the light-emitting element is arranged at the bottom of the groove, the light distributing element comprises a panel, first lenses and second lenses, the first lenses and the second lenses are arranged on the panel at intervals, the light distributing element is rotatably connected to the top of the groove, light rays emitted by the light-emitting element are refracted by the first lenses and the second lenses in different modes, and the light distributing element can rotate, so that the first lenses and the second lenses can be alternately aligned with the light-emitting element. The shortcoming that a light-emitting angle of an existing spot lamp cannot be adjusted is overcome, and accordingly the spot lamp has the advantages of simple structure and adjustable light-emitting angle.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to a spotlight with an adjustable luminous angle. Background technique [0002] A kind of LED spotlight in the prior art, including lamp cap, lamp holder, power supply circuit board, heat dissipation aluminum body, LED lamp bead, lens and lens fixing ring and other components, lamp cap and lamp holder are assembled together, lamp holder and heat dissipation aluminum body Assembled together, the power supply circuit board is assembled in the lamp holder. The LED spotlight of this structure has a non-adjustable light angle, that is, the range of light emitted by the LED spotlight of this structure is certain, and the light irradiation range is certain. The range cannot be made larger or smaller. For example, the authorized announcement date is October 9, 2013, and the Chinese invention patent with the patent number 201310270627.4 discloses an LED spotlight imitating the light of an incand...
