Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Refer to Fig. 1 and Fig. 2, present embodiment discloses a kind of LED lamp structure with large beam angle, comprise electric conductor 1, heat radiation body 2, electric component 3, heat conduction column 4, flexible light source plate 5 and lampshade 6; Electric conductor 1 is arranged on the end of heat radiation body 2; It is inner that electric component 3 is installed on heat radiation body 2, and electric component 3 is electrically connected with electric conductor 1; Heat conduction column 4 comprises the column main body 9 in hollow prism shape, one end of column main body 9 heat radiation body 2 dorsad is provided with in pyramid-shaped cone head part 10, column main body 9 is provided with towards one end of heat radiation body 2 transition part 11 extended in the conical surface, and the end of transition part 11 is provided with skirt section 12; Heat conduction column 4 is connected with heat radiation body 2 by skirt section 12; Flexible light source plate 5 is overlying on the surface of heat conduction column 4, and flexible light source plate 5 surface is provided with LED photogenic granules and electrical contact, and flexible light source plate 5 is electrically connected with electric component 3 by electrical contact; Lampshade 6 and heat radiation body 2 are connected and installed, and cover at heat conduction column 4 outside.
The LED of prior art adopts the light source board of plane formula, and LED photogenic granules is arranged in the surface of light source board, and structure is comparatively single.The beam angle of this LED is less, and be no more than 180 ° in theory, and cannot meet the demands for the brightness of illumination of radial direction in practical application, thus its actual beam angle is lower than 180 °.The illumination zone of this LED is very limited, during installation, lampshade 6 must be down, although this LED still can meet general illumination needs, if but some special light fixture such as: wall lamp, some smallpox pendent lamp etc., lampshade 6 is needed to install upward, then this LED beam angle is too narrow, and light is irradiated on ceiling, and the spread of light cannot meet lighting demand.
And the present invention is relative to the essential distinction of prior art: present invention employs flexible light source plate 5 and replace traditional plane formula light source board, correspondence have employed heat conduction column 4 and replaces traditional plane formula heat sink plate.Flexible light source plate 5 can carry out flexible flexural deformation, thus the column main body 9 of heat conduction column 4 of can fitting completely and cone head part 10 surface, and LED photogenic granules is also close to thereupon and is located on each prismatic surface of column main body 9 and each conical surface of cone head part 10.The LED photogenic granules be distributed on each conical surface of cone head part 10 by light towards axial scattering, can be mainly used in the bright dipping axially of LED entirety; The LED photogenic granules be distributed on each prismatic surface of column main body 9 can by light towards radial scattering, and scattering angle is comparatively large, has also taken into account the bright dipping of going up dorsad simultaneously.Thus Total Product beam angle of the present invention is much higher than the LED of prior art, and beam angle is greater than 180 °, can carry out bright dipping dorsad, even if also can provide enough brightness of illuminations by counter for LED product dress.
As preferably, the column main body 9 of described heat conduction column 4 is hollow six prism, and cone head part 10 is hexagonal pyramid; Flexible light source plate 5 is overlying on six prisms and hexagonal pyramid surface.
From the uniformity of light scattering, the cylinder of column main body 9 is more much more favourable in theory.But flexible light source plate 5 preferably fits in even curface, thus the compactness can fitted between effective guarantee flexible light source plate 5 and column main body 9.And column main body 9 preferably can provide enough large cylinder area for heat conduction.Meanwhile, the bending of flexible light source plate 5 entirety can also be reduced.Consider the problem such as scattering and parts laminating of light, column main body 9 adopts hollow six prism most suitable, and corresponding cone head part 10 is also set to hexagonal pyramid.
As preferably, the transition part 11 of described heat conduction column 4 offers two rectangle hollow outs 13 be oppositely arranged, electric component 3 is electrically connected with flexible light source plate 5 through rectangle hollow out 13.In installation process, electric component 3 can pass through rectangle hollow out 13 and directly directly contacts with the electrical contact on flexible light source plate 5, thus is electrically connected with flexible light source plate 5, by electrical energy transfer to all LED photogenic granules on flexible light source plate 5.
As preferably, described heat radiation body 2 comprises insulation crust 7 and heat conduction inwall 8; The inwall that heat conduction inwall 8 is close to insulation crust 7 is arranged, and the skirt section 12 of heat conduction column 4 press-fits within heat conduction inwall 8.
In order to ensure being connected between heat conduction column 4 with heat conduction inwall 8 closely, and easy for installation, as further preferred, the skirt section 12 of described heat conduction column 4 is connected with interference between heat conduction inwall 8.
The high heat capacity produced when LED photogenic granules is luminous easily affects the service life of LED photogenic granules, even burns out LED photogenic granules, affects the functional reliability of LED product.The normal work of LED is premised on good heat radiation.The heat that LED photogenic granules sends is passed to rapidly heat conduction column 4, and heat conduction column 4 has good heat conductivility, and heat is passed to rapidly heat radiation body 2.Heat conduction inwall 8 and the heat conduction column 4 of heat radiation body 2 fit tightly, between the two can transferring heat, through outwardly being scattered and disappeared by insulation crust 7 after heat is passed to heat conduction inwall 8, reach good radiating effect.Insulation crust 7 also has the function of beautifying product and insulation simultaneously, prevents Danger Electric shock risk.
In order to improve the heat conduction between flexible light source plate 5 and heat conduction column 4 further, the heat dispersion of optimizing product entirety, as further preferably, scribbles heat-conducting glue between described flexible light source plate 5 and heat conduction column 4.
A kind of LED lamp structure with large beam angle provided by the invention, beam angle breaks through 180 °, obviously the beam angle of the LED of prior art is better than, thus make the coverage of light illumination wider, the effect of bright dipping dorsad can be reached, thus can freely be applied to more how different environment and lighting apparatus.The heat dispersion of product is good, the safety and reliability of safeguard work.And the structure of Total Product is simple, easy volume production, has wide market prospects.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
