Abstract

The utility model is a light-beam adjustable L E D light fitting, comprising a lamp holder and a lamp shell, wherein one part of the lamp holder is provided with a lighting module with an L E D lamp which is arranged on the lighting module with an angle. The lamp shell is arranged on the lamp holder and the lighting module is accommodated inside the lamp shell, wherein a reflection surface of a special curvature is arranged on the inner surface of the lamp shell. The direction of illumination of the L E D lamp is toward the reflection surface; therefore, the LED lamp light is reflected outward by the reflection surface. In addition, the lamp holder or the lamp shell is arranged on the L E D light fitting in a rotation method, thereby the lamp holder or the lamp shell can be rotated to change relative position of L E D light to the reflection surface to change the light range.

One lamp housing, be to be combined on the described lamp socket with the mode activity that can rotate about, described illumination module is placed in the lamp housing, wherein said lamp housing inner face is the reflecting surface that is provided with a specific curvature, the illumination direction of LED lamp is towards described reflecting surface, and the light source of described LED lamp can be by described reflecting surface to external reflectance.

For achieving the above object, the technical solution adopted in the utility model also comprises:

One lamp housing, be that activity is combined on the described lamp socket, making can be with respect to described lamp housing rotation in conjunction with the described lamp socket in back, and the LED lamp of described illumination module is rotated in lamp housing, described lamp housing inner face is the reflecting surface that is provided with a specific curvature, and the light source of described LED lamp can be by described reflecting surface to external reflectance.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: can be with respect to the design of described lamp housing 3 rotations with described lamp socket 2, and the LED lamp 211 that makes described illumination module 21 is rotated in lamp housing 3, feasible light when projection is reflected face 31 behind external reflectance, rotation by LED lamp 211, and the change (as shown in Figure 7) of formation illumination range, so the utlity model has advantage simple in structure, easy to use, that cost is low.

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.

In addition, please consult Fig. 7 again, different is so that the illumination range of different beam angles can be provided during lamp housing 3 rotation in previous embodiment, the utility model also can be with after lamp housing 3 and lamp socket 2 movable the combinations, described lamp socket 2 can be with respect to described lamp housing 3 rotations, and the LED lamp 211 that makes described illumination module 21 is rotated in lamp housing 3, feasible light when projection is reflected face 31 behind external reflectance, rotation by LED lamp 211, change the relative position of LED lamp 211 light sources and reflecting surface 31, and form the change of illumination range.
