In the present embodiment, the lighting angle of lampshade is 165 degree.
Preferably, the back side of base plate is evenly longitudinally provided with heat radiation groove, and base plate adopts aluminium sheet to make, and reaches good heat sinking function, directly can extend product service life.
Preferably, the both sides of base plate are provided with biside plate, and the two ends of base plate are removably fixed with two mount pads, and base plate, side plate and mount pad are fixedly connected to form the groove that a size coordinates with pcb board, pcb board is located in this groove, and on this pcb board drip have one deck to cover the transparent watertight glue of whole groove.
Preferably, the medial surface of biside plate is also provided with the spacing raised line coordinating with pcb board end face and contact.Mount pad bottom surface extends outward an installing plate parallel with described base plate, and installing plate is provided with bar shaped screw hole.The two ends of base plate are provided with the connecting line be electrically connected with pcb board, and connecting line stretches out through mount pad.
The end face in lampshade end face of the present utility model and incident chamber is plane, incident chamber is be divided into the taper that two parts diameter reduces gradually, and unique Lens Design, breaches conventional lenses lighting angle 150 degree, reach 155 degree, substantially increase the light emitting region of lamp bar.Base plate adopts heat radiation groove design, and the heat that LED is produced can leave fast, extends the service life of lamp bar.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the high-power hard lamp bar that the utility model proposes, comprising: base plate 1, the pcb board 2 being located at base plate 1 end face, evenly distributed LED 3, the lampshade 4 covered in LED 3 on pcb board 2.
As shown in Figure 2,3, lampshade 4 is solid hemisphere, and lampshade 4 bottom center is provided with the incident chamber 41 for holding LED 3.The end face of lampshade 4 and the end face in incident chamber 41 are plane, and the lower openings place sidewall 43 in incident chamber 41 is cylindrical, and the upper portion side wall 44 in incident chamber 41 is the taper that diameter is reduced gradually by cylindrical top surface.The light that LED 3 sends is after the refraction and transmission effect in incident chamber 41 and lampshade 4 end face (i.e. exit facet), and the injection angle of light occurs repeatedly to change, and light is penetrated to all directions from lampshade 4, improves the light emitting region of lamp bar.
The bump structure 42 of lampshade 4 bottom surface uniformly continous distribution, bump structure 42 can form optical scattering structure, after light enters lampshade 4, part light reflects when reaching lampshade 4 end face, when reflexing to the bottom surface of lampshade 4, this bump structure 42 can make light wider be reflected back lampshade 4 end face, the light of lampshade 4 is scattered evenly.In the present embodiment, the lighting angle of lampshade 4 is 165 degree.
Preferably, as shown in Figure 4,5, the back side of base plate 1 is evenly longitudinally provided with heat radiation groove 11, and the setting of heat radiation groove 11 can increase base plate 1 and the contact area of air, is left by the heat on base plate 1 fast.Base plate 1 can adopt aluminium sheet to make, and aluminium material has preferably heat dispersion, and base plate 1 also can be helped to dispel the heat as early as possible.
