The utility model purpose provides a kind of light fixture that can change light angle, and this light fixture can be realized the adjustment of irradiation angle under the situation of not passing through the rotation lamp bracket.
In order to solve above-mentioned technical problem, the utility model proposes a kind of LED light fixture that becomes the illumination firing angle that rotates, and comprises lampshade, is LED lamp device in the lampshade, and said lampshade is the cylindrical barrel of half opening; Said cylindrical shell comprises the transparent light guide flaggy of internal layer and is attached to the clear support layer on the leaded light flaggy outer surface; On one end of the opening of cylindrical shell base is arranged, on base, be provided with groove, the supporting layer of cylindrical shell is buckled on the groove, and through the groove location, the leaded light flaggy is fixed on the base; Be provided with a hole that supplies lamp stand to pass in the middle of the base; Said groove is an endless groove; Said base is that two half of bodies are spliced;
At said supporting layer outer surface reflector layer is arranged, the radially subtended angle that this reflector layer covers on the cylindrical shell is less than or equal to 180 ° of angles.
Preferably: the top of said cylindrical shell is flat-top or spherical crown top.
Preferably: the top at cylindrical shell is provided with handle.
Preferably: said clear support layer is glass or transparent resin material.
Preferably: said LED lamp device is a LED lamp rod, and the lamp rod is located on the lamp stand.
Preferably: said reflector layer is aluminium coated or silver coating.
Preferably: also have enamelled coating at said reflector layer outer surface.
Preferably: said radially subtended angle is 180 °, 120 ° or 90 °.
The beneficial effect of the utility model:
Compare prior art; The utility model is provided with reflector layer on the outside of LGP; This structure can make this light that is provided with the part exiting surface of reflector layer be reflected back toward in the LGP, has improved the brightness of the whole bright dipping of LGP, has promptly increased the emitting brightness that non-reflector layer is covered part.When needing the adjustment irradiating angle,, only need the rotation supporting layer can realize irradiation angle because supporting layer is shelved on the groove.The utility model simple in structure, easy to operate, it is free to regulate irradiating angle, and need not adjust lamp stand, and its structure is more firm, is not easy to be out of order.
