Technical field
The utility model relates to a kind of big-angle LED lamp, belongs to the LED field of illumination lamp technology.
Background technology
The basic structure of LED is an electroluminescent semi-conducting material; place on the leaded shelf; then use epoxy sealing around; play the effect of protection internal core; so the anti-seismic performance of LED is good, also because its life-span is long, wavelength can be selected because of purposes, easy to make, operating cost is low, power consumption is little and non-environmental-pollution is widely used.At present, adopt the illuminating lamp of led light source by the market extensive use.In the existing LED bulb, the LED light emission direction generally all be set to opposite with lamp holder.Because the light emission direction of LED generally is forward, is subject to the restriction of its lighting angle, existing LED bulb is luminous to only have a taper angle, and the light at its lamp holder place is darker, can not be the same as with the fluorescent lamp bulb all directions uniformly light-emitting as traditional incandescent light bulb.Therefore, existing LED lamp or undesirable.
Summary of the invention
The purpose of this utility model is as overcoming the deficiencies in the prior art, provide a kind of LED lamp that can the wide-angle uniformly light-emitting, and this LED modulated structure is simple, with low cost.
The technical solution of the utility model: for realizing the purpose of this utility model, a kind of big-angle LED lamp of the present utility model, comprise lamp holder, lampshade, driver, LED assembly, radiator and shell, driver is by power supply upper casing inclusion relative to the power supply lower casing, the LED assembly is connected on the radiator by screw one, wherein, is provided with a reflector in the bottom of LED assembly, reflector is connected on the LED assembly by screw two, and reflector is provided with the reflective blade of wide-angle downwards.
Further, the quantity of described blade is 4～10.
Further, described reflector also is provided with a columniform hollow base, and described blade scatters from the outer rim of base end face is outward-dipping.
Further, the angle of inclination beta of the axis of described blade and base is 55～70 °.
Further, the angle of inclination beta of the axis of described blade and base is 63 °.
In addition, described blade is interior narrow outer wide shape, and as flat scull shape, its blade two sidelines are intersected in the base central point.
Further, the both sides of described blade are 5～18 ° with respect to the angle α at described base center.
At last, reflector is the device of being made by the plastics of high reflecting rate.
Compared with prior art, the reflector of big-angle LED lamp of the present utility model is the emission principle that utilizes light, luminous component with the LED lamp, it is reflector that one reflection unit is set, and this reflection unit is made with the plastics of high reflecting rate, and is provided with blade, by blade quantity and the isoparametric design of angle, the light that shines this reflection unit blade below is reflected downwards by blade, light can be reached surpass 180 ° direction, thereby form the large-angle LED bulb.The technical solution of the utility model is simple, is widely used, and is worthy to be popularized.
