The specific embodiment
Please with reference to Fig. 1 and Fig. 3, the large-angle LED illuminating lamp 100 of first embodiment of the invention comprises a body 10, a substrate 20, a column 30, led light source 40, a reflecting component 50, a bulb shell 60.This substrate 20 is arranged on the top of this body 10; This column 30 is arranged on the middle part of the end face of this substrate 20; The bottom of this reflecting component 50 is fixed on this substrate 20, and these led light sources 40 are distributed on this column 30, and this bulb shell 60 is covered with this column 30 and this substrate 20.
Please with reference to Fig. 1 and Fig. 3, this column 30 is positive pentagonal prism shape, and this column 30 comprises five sidewalls 32 and an end face 34, and this substrate 20 of these sidewall 32 approximate vertical is provided with.
Please with reference to Fig. 1 and Fig. 3, these led light sources 40 comprise 10 first led light sources 42 and 4 second led light sources 44.These first led light sources 42 are disposed in an evenly spaced relation on the sidewall 32 of this column 30 around this column 30, and all first led light sources 42 are distributed on the same plane, and this plane is parallel with this substrate 20.These first led light sources 42 distribute two on each sidewall 32 of this column 30; And these first led light sources 42 are distributed on the sidewall 32 of this column near the position at top 34, and the light that makes these first led light sources 42 send is radiated at the side and the bottom of this bulb shell 60.These second led light sources 44 comprise four LEDs, and this four LEDs is circle-shaped distribution on the end face 34 of this column, but the quantity of these second led light sources 44 and distributing position can be adjusted according to actual needs.
Please with reference to Fig. 3; This reflecting component 50 is round table-like; And these reflecting component 50 centers are provided with the installing hole that runs through end face and bottom surface, and the cross-sectional diameter of this installing hole is slightly larger than the external diameter of a circle of the cross section of this column 30, make this reflecting component 50 can annular be arranged on the bottom of this column 30.The bottom of this reflecting component 50 is fixed on this substrate 20.The side of these reflecting component 50 these reflecting components 50 is coniform reflective surface 52; And the angle that the end face of this reflective surface 52 and this substrate 20 forms is between 15 ° to 45 ° (as shown in Figure 3); Make the light of these these substrate 20 directions of first led light source, 42 directives after 52 reflections of this reflective surface; Be distributed on these bulb shell 60 bottoms position, thereby increase this regional brightness near this body 10.
Please with reference to Fig. 2 and Fig. 3, this bulb shell 60 is provided with scattering material, makes the diffusion angle of light of this bulb shell 60 of directive increase.The ball cell-shell structure that this bulb shell 60 is a bottom opening; The middle part of this bulb shell 60 is provided with protuberance 62 on the direction away from first led light source 42 on the sidewall 34 of this column 30; This bulb shell 60 has maximum diameter in the position with the Plane intersects at these first led light sources 42 places; The light of described this protuberance 62 of first led light source, 42 directives to all directions diffusion, makes that the light diffusion angle of this large-angle LED illuminating lamp 100 is bigger behind these protuberance 62 luminous intensity distributions.
During work; The light that these second led light sources 44 send mainly is radiated at the top of this bulb shell 60; The light that these first led light sources 42 send mainly shines the side and the bottom of this bulb shell 60; The light part directive substrate 20 that these first led light sources 42 send is distributed on this bulb shell 60 bottoms inwall near these body 10 tops after reflective surface 52 reflections through this reflecting component 50, passes through the secondary light-distribution effect of this bulb shell 60 again; The particularly secondary light-distribution effect of the protuberance 62 of this bulb shell 60, this large-angle LED illuminating lamp 100 is realized the wide-angle illumination.
In sum; This large-angle LED illuminating lamp 100 is through set inside one column 30 at this bulb shell 60; These first led light sources 42 distribute respectively on a plurality of sidewalls 32 of this column 30; The part light that secondary light-distribution effect, especially these first led light sources 42 of this bulb shell 60 of process send makes this large-angle LED illuminating lamp 100 realize wide-angles illumination through the secondary light-distribution of the protuberance 62 of this bulb shell 60.Because this large-angle LED illuminating lamp 100 utilizes the given shape of arranging of first led light source 42 and bulb shell 60 to realize that wide-angle is luminous, need not the installing plate splicing of a plurality of inclinations, thereby have advantage simple in structure, that be convenient to make.Through bottom this reflecting component 50 is set, can increases the brightness of these bulb shell 60 bottoms, make and put in order the light more even distribution at this column 30.Through these second led light sources 44 are set, can remedy the problem of these large-angle LED illuminating lamp 100 top luminance shortage on the end face 34 of this column 30.
Please with reference to Fig. 5 and Fig. 6; The large-angle LED illuminating lamp 100a of second embodiment of the invention and the difference of aforesaid large-angle LED illuminating lamp 100 are; This large-angle LED illuminating lamp 100a also comprises a reflexed light ring 70, and the end face 34 of the column 30 of this large-angle LED illuminating lamp 100a is not established these second led light sources 44.This reflexed light ring 70 is arranged on the periphery of this reflecting component 50, and these reflexed light ring 70 corresponding said first led light sources 42 are provided with near the bottom of this bulb shell 60.The lateral wall of this reflexed light ring 70 is close to the madial wall of this bulb shell 60a bottom, and the height of this reflexed light ring 70 is lower than the height of these first led light sources 42.The angle that the madial wall 72 of this reflexed light ring 70 and the end face of this substrate 20 form is between 100 ° to 145 °.The madial wall of this reflexed light ring 70 is used for to the top of this bulb shell 60 reverberation.The part light that these first led light sources 42 send is directly or through this madial wall 72 of directive indirectly after the reflection of this reflecting component 50; Through after the reflection of this madial wall 72; The top of this bulb shell of directive 60a; Increase the brightness at this large-angle LED illuminating lamp 100a top, make the top of this column 30 need not to be provided with LED.The structure that this bulb shell 60a adopts two parts to fasten is convenient to the installation of this reflexed light ring 70.
Please with reference to Fig. 7; The large-angle LED illuminating lamp 100b of third embodiment of the invention and the difference of aforesaid large-angle LED illuminating lamp 100 are; The bottom of the bulb shell 60b of this large-angle LED illuminating lamp 100b is the planar reflecting segment 64 of back taper; This reflecting segment 64 is provided with reflecting coating, and the end face 34 of the column 30 of this large-angle LED illuminating lamp 100b is not established these second led light sources 44.These reflecting segment 64 corresponding said LED42 light sources are provided with.The reflecting segment 64 of this bulb shell 60b bottom is that back taper is planar, makes that the reflecting effect that is located at the reflector layer on this reflecting segment 64 is better.The part light that this first led light source 42 sends directly or through after the reflection of this reflecting component 50 shines on this reflector layer indirectly; After the reflection through this reflector layer; The top of this bulb shell of directive 60b; Increase the brightness at this large-angle LED illuminating lamp 100b top, make the end face of this column 30 need not to be provided with LED.
