Therefore, how designing the strong LED bulb diffuser of a kind of spotlight effect is the technical problem that needs to be resolved hurrily in the industry.

Summary of the invention

Main purpose of the present utility model is to provide a kind of LED bulb reflection shield, is intended to improve the spotlight effect of reflection shield, reduces vignette, and the irradiation distance of the light that LED sends is increased.

The utility model proposes a kind of LED bulb reflection shield, LED light source post in its profile and LED bulb is adaptive, be provided with on the side of described reflection shield with adaptive LED light source post side on LED light-emitting window one to one, described light-emitting window on each side is provided with two and longitudinal arrangement at least, laterally be provided with a reflecting strips between adjacent described light-emitting window on each side, the face that the described light-emitting window that is adjacent on described reflecting strips is corresponding is the first reflective surface.

Preferably, the angle of inclination of the relatively described light-emitting window of described the first reflective surface is 105 ° ~ 115 °.(angle of inclination of described the first reflective surface relative level face is 15 ° ~ 25 °.）

Preferably, the arranged on left and right sides at described light-emitting window is provided with the second reflective surface.

Preferably, the angle of inclination of the relatively described light-emitting window of described the second reflective surface is 140 ° ~ 155 °.(angle of inclination of described the second relative longitudinal surface of reflective surface is 25 ° ~ 40 °.）

Preferably, be provided with the top platform of positive prism-frustum-shaped or orthopyramid shape in the upper surface of described reflection shield, described top platform extends upward formation for the upper surface along described reflection shield, and the side of described top platform is corresponding one by one with the side that described reflection shield is provided with described light-emitting window.

the side of the utility model LED bulb reflection shield be provided with adaptive LED light source post side on LED light-emitting window one to one, light-emitting window on each side is provided with two and longitudinal arrangement at least, laterally be provided with a reflecting strips between adjacent light-emitting window on each side, the face that the light-emitting window that is adjacent on reflecting strips is corresponding is the first reflective surface, a left side at light-emitting window, right both sides are provided with the second reflective surface, the light-ray condensing that the second reflective surface coordinates the first reflective surface the LED that is placed in light-emitting window can be sent, and reflect away, reduce vignette, efficient light brightness is improved, thereby the brightness that in each light-emitting window, LED sends is strengthened, irradiation distance increases.
