Specific embodiment
The present invention is described in further detail below by specific embodiment combination attached drawing.
A kind of LED wall wash lamp is present embodiments provided, this LED wall wash lamp is mostly installed at the large-scale field such as cruise center night scene
Institute.
As depicted in figs. 1 and 2, the LED wall wash lamp of the present embodiment mainly includes lamp body 1 and lampshade 2, is tied based on lamp body 1
Structure, one end of lamp body 1 are equipped with LED light source 3, and lampshade 2 is mounted on one end of lamp body 1, LED light source is covered on inside, 2 face of lampshade
It is transparent material to the side of lamp body 1, opposite side is lighttight material, and reflector 4 is equipped in lampshade 2, is reflected
Cup 4 is used for the light reflection that LED light source 3 is sent out to the wall of installation.
The midpoint of reflector 4 is close to LED light source 3, and surrounding is gradually distance from LED light source 3, and the side wall of reflector 4 is in cross section
The upper curved line in indent, the indent of curved line be for reflecting surface, so as to which reflector 4 is located on LED light source 3,
It the light reflection that LED light source 3 can be sent out and scatters to be more uniformly distributed.
Reflector 4 passes through numerous studies and experiment, the curvature half of curved line according to itself 120 ° of angular of reflection of light source
Diameter is 222mm, arc length 84mm, a diameter of 165mm of reflector 4, highly for 16.5mm, it can be achieved that the maximization of reflected light,
Realize best reflecting effect.
Reflector 4 in the present embodiment is handled by highlighted anodic oxidation and fine grinding sand, reduces the weight of reflector 4, with
The size of the present embodiment reduces 350 gram weights.Wherein, with reference to diffusing reflection principle, at the best shot blasting particles of using effect
Reason.
In order to improve the heat dissipation effect of lamps and lanterns, the outer surface of lamp body 1 be equipped with cooling fin 5, cooling fin 5 have it is multiple, be
The circular ring plate being uniformly arranged at equal intervals on lamp body 1, and cooling fin 5 is equipped with one end of LED light source 3 to another from lamp body 1
End becomes larger, and forms fin structure, whole that frustum cone structure is presented.
In other embodiments, cooling fin 5 or right-angled trapezium, are evenly distributed on the outer surface of lamp body 1, equally may be used
Realize heat dissipation effect.
