The specific embodiment
Figure 1 shows that the three-dimensional exploded view of large-angle LED illuminating lamp first embodiment of the present invention.This large-angle LED illuminating lamp 100 comprises a body 10, a positioning table 20, six groups of identical light sources 30, a reflecting component 40 and bulb shells 50.These body 10 1 ends are connected with this positioning table 20, and the other end is electrically connected with a lamp socket (figure does not show).These six groups of light sources 30 are separately positioned on this positioning table 20.This reflecting component 40 is arranged on this positioning table 20.The bottom of this bulb shell 50 is connected with this body 10, forms a chamber, in order to hold this positioning table 20, this light source 30 and this reflecting component 40.This bulb shell 50 is provided with light transmission scattering material.
Please refer to Fig. 1, Fig. 3 and Fig. 4, every group of light source 30 comprises lens 32, a led chip 34 and a wiring board 36.These lens 32 transparent semielliptical types, these lens 32 comprise that a bottom surface 322, is located at the semielliptical shape exit facet 324 and a plane of incidence 326 of these bottom surface 322 1 sides.This bottom surface 322 is provided with a groove 321 at an end of these lens 32 major axis, and the bottom surface of this groove forms this plane of incidence 326.Please refer to Fig. 4, these lens 32 are provided with three reference columns 328 in its bottom surface 322 around this groove 321.This led chip 34 is fixed on this wiring board 36.36 pairs of this wiring boards should lens 32 three reference columns 328 be respectively equipped with three locating holes 361.During assembling, these lens 32 are fixedlyed connected with the locating hole 361 of this wiring board 36 by its reference column 328, and simultaneously, the groove 321 of these lens 32 is located at around this led chip 34.These lens 32 are used for changing the distribution in the space of light that this led chip 34 sends, make more rays in the direction of the bottom of this bulb shell 50 of deflection, promptly the direction of this body 10 distributes.
Please refer to Fig. 1 and Fig. 3, this positioning table 20 is positive six terrace with edge shape structures, the comprising an end face 22, a bottom 24 and connect six sidewalls 26 of this end face 22 and bottom 24 of this positioning table 20.The size of this bottom 24 makes these sidewalls 26 in the setting that slopes inwardly on the direction of this end face 22 greater than the size of its end face 22.The end face 22 of this positioning table 20 is provided with an accepting hole 21.The top of this body 10 is provided with a heat transfer substrate 12, and the end face of this heat transfer substrate 12 is the plane.The bottom 24 of this positioning table 20 is installed on this heat transfer substrate 12.Six sidewalls 26 of this positioning table 20 respectively with 12 one-tenth 110 ° ± 5 ° angles of this heat transfer substrate.The wiring board 36 of six groups of light sources 30 is flattened on this six sidewalls 26 respectively, makes 12 one-tenth 110 ° ± 5 ° angles of these light sources 30 and this heat transfer substrate.Each led chip 34 is 16mm to the distance of this heat transfer substrate 12, the end face 22 of this positioning table 20 is 18mm to these heat transfer substrate 12 distances, makes the distance of this led chip 34 to the end face 22 of the distance of this heat transfer substrate 12 and this positioning table 20 to this heat transfer substrate 12 than being 8: 9.
Please refer to Fig. 1 and Fig. 3, this reflecting component 40 comprises a protruding spherical reflective surface 42 and a fixed leg 44.This fixed leg 44 is connected under this reflective surface 42.This reflecting component 40 makes this reflecting component 40 be fixed on this positioning table 20 by this fixed leg 44 is fixed in the reception hole 21 of this positioning table 20.The light that this reflecting component 40 is used for being come by this bulb shell 50 inwalls reflection reflexes to the top of this bulb shell 50, to strengthen the brightness at these bulb shell 50 tops, makes these LED illuminating lamp 100 light distribution more even.
Please refer to Fig. 1 to Fig. 4, during these LED illuminating lamp 100 work, because six groups of light sources 30 are separately fixed on six sidewalls 26 of this positioning table 20, make these light sources 30 form a circle, all directions around this LED illuminating lamp 100 are luminous, and this just makes the lighting angle of these LED illuminating lamp 100 integral body increase.By this lens 32 are set on the led chip 34 of each light source 30, the direction of more rays at this body 10 of deflection can be distributed, strengthen the light of this LED illuminating lamp 100 towards these body 10 directions, remedy that these light sources 30 are provided with in obtuse angle with this heat transfer substrate 12 and defective that the light that distributes to these body 10 directions that causes tails off, thereby make the lighting angle of these LED illuminating lamp 100 integral body bigger.In order to make this LED illuminating lamp 100 have better illumination effect, special this reflecting component 40 of on the end face 22 of this positioning table 20, setting up, be used for the light that these bulb shell 50 inwalls reflect is reflexed to bulb shell 50 tops, make the whole light of this LED illuminating lamp 100 be more evenly distributed by force.
Please refer to Fig. 5 and Fig. 6, Fig. 5 is not for installing the distribution curve flux figure of the LED illuminating lamp of lens 32 in the first embodiment of the invention, and as seen from the figure, the half light intensity angle that the LED illuminating lamp of lens 32 is not installed is approximately 260 °.Fig. 6 installs the distribution curve flux figure of the LED illuminating lamp of lens 32 for first embodiment of the invention, as seen from the figure, the half light intensity angle that lens 32 back LED illuminating lamps are installed is approximately 300 °, and this explanation is by installing the lighting angle that these lens 32 can effectively increase this LED illuminating lamp 100.
In sum, this LED illuminating lamp 100 is by being arranged on these light sources 30 on the sidewall 26 of this positioning table 20, on each led chip 34, lens 32 are set, utilize these lens 32 that the light that this led chip 34 sends is more distributed on the direction of this body 10 of deflection, thereby realize that wide-angle is luminous.Compared with prior art, this LED illuminating lamp 100 is by being provided with these lens 32, and light source needn't be set at the end face of this positioning table 20, has advantage of simple structure.In addition,, can carry out optical profile once more, make that the light distribution of these LED illuminating lamp 100 integral body is even the light that penetrates because this bulb shell 50 is provided with scattering material.
In addition, adopted the fixed form that is articulated on this positioning table 20 for the set reflecting component 40 of the light distribution that strengthens these bulb shell 50 tops in the first embodiment of the invention.In practice, can also adopt to be bonded on this positioning table end face 22 or the buckle connection waits other modes.If less demanding, also this reflecting component 40 can be set to light distribution.These lens 32 can also adopt other light distribution element to realize same optical profile by the spatial distribution of the light that changes its plane of incidence 326 and cooperating of exit facet 324 this led chip 34 and send in the practice.This positioning table 20 can also adopt the stage body structure of the bottom of other shapes greater than end face according to the quantity of the light source 30 that will install except adopting six terrace with edges, so that make light source 30 and heat transfer substrate 12 be predetermined obtuse angle and transmit the heat that light source 30 produces.
Obviously, those skilled in the art can carry out various changes and modification to the embodiment among the present invention and not break away from the spirit and scope of the present invention.Like this, if these in the embodiment of the invention are revised and modification belongs to claim of the present invention and the scope that is equal within, then the embodiment among the present invention also is intended to comprise these changes and modification interior.
