Specific embodiment
In order to which the purpose of this utility model, technical solution, good effect is more clearly understood, pass through following embodiment pair
The utility model is further elaborated.Description below for specific embodiment is only used for explaining the utility model,
Do not limit the utility model.
In the present invention it should be noted that the orientation or positional relationship of the instructions such as term "inner" "outside" is based on attached
Orientation or positional relationship shown in figure, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of utility model.
The blackboard lights 1 of the utility model embodiment are described below with reference to Fig. 1-Fig. 3.
A kind of blackboard lights 1 of adjustable light distribution, including lamp body 11, illuminating module 12 and for drive illuminating module 12 rotate
Rotary components 13.
As shown in Fig. 2, light source board 122 and lens 123 that illuminating module 12 has bracket 121 and is mounted on bracket 121.
Bracket 121 has a plane and two arcwall faces, and two arcwall faces are symmetrically connected in planar side, and light source board 122 is parallel to described
Plane, and be plugged in bracket 121, lens 123 are parallel to light source board 122, and are plugged on the arcwall face far from the plane
One end on.The grafting of light source board 122 and lens 123 by opening up through-hole on bracket 121, makes light source board 122 and lens
123 with 121 clearance fit of bracket.
It is equipped with the mounting groove 111 for mounting bracket 121 in lamp body 11, is equipped in mounting groove 111 and is rotated for bracket 121
The angle design of rotation angle A, rotation angle A are 0-20 °.Then, centre rotational axis of the bracket 121 in mounting groove 111 is light source
The line of LED lamp bead centre of luminescence point on plate 122.When bracket 121 is in mounting groove 111, two arcwall faces and mounting groove 111
Inner wall is in contact, plane angle needed for centre rotational axis rotation.In addition, lamp body 11 further includes the end cap at both ends
112, lamp body 11 is that aluminium extruded is integrally formed with mounting groove 111, when assembling the lamp, first by the whole axial grafting of illuminating module 12
In mounting groove 111, then end cap 112 is fixed on to the end of lamp cap 11 again.
