Description of reference numerals: the LED light fixture that 1-tool light beam is adjusted; The 2-lamp socket; The 21-illumination module; The 211-LED lamp; The 212-radiator; The 213-circuit arrangement; The 3-lamp housing; The 31-reflecting surface.
The specific embodiment
See also Fig. 1~Fig. 4, graphic content is an embodiment of the LED light fixture 1 of the utility model tool light beam adjustment, and it mainly comprises a lamp socket 2 and a lamp housing 3.
Described lamp socket 2 one ends are provided with the illumination module 21 of a LED lamp 211, and described LED lamp 211 is to be an angle Θ (as 75 degree~105 degree) with respect to level direction R forward to be arranged on the described illumination module 21, so that described LED lamp 211 presents illumination direction up or down.The circuit arrangement 213 that other described illumination module 21 includes a radiator 212 that is connected with LED lamp 211 in addition and described LED lamp 211 power supplys are provided.
Described lamp housing 3 is to be combined on the described lamp socket 2 with the mode activity that can rotate about, described illumination module 21 is placed in the lamp housing 3, wherein said lamp housing 3 inner faces are the reflectings surface 31 that are provided with a tool specific curvature, and the illumination direction of LED lamp 211 is towards described reflecting surface 31, wherein said reflecting surface 31 can be designed to be one in advance because of the needs on using to have the shiny surface of specific curvature or is a non-smooth burnishing surface with asperities shape, the light of described LED lamp 211 light source projects can be reflected by described reflecting surface 31, and when rotation lamp housing 3, make the relative position that changes LED lamp 211 light sources and reflecting surface 31, and form the change of illumination range.
During enforcement, the utility model during fabrication can be earlier according to user's demand, the intensity effect of the beam angle that reach in advance, and the required curvature of design reflectivity face 31.Therefore, referring again to the 3rd, 4 figure, when LED lamp 211 ray cast that are arranged on lamp socket 2 one ends during at lamp housing 3 reflectings surface 31, can be by described reflecting surface 31 and with light to external reflectance, when user's desire changes illumination range, can rotate lamp housing 3, the reflecting surface 31 that makes lamp housing 3 inner faces is because of after lamp housing 3 is rotated, make the relative position that changes LED lamp 211 light sources and reflecting surface 31, and produce the variation of illumination range.
