The specific embodiment
Below in conjunction with accompanying drawing, technology contents of the present utility model is explained in detail.
As shown in Figure 1, integrated high light efficiency LED light fixture of the present utility model comprises lamp housing 1, lampshade 2, reflecting layer 3, LED light emitting module 4, cooling base 5 and driver 6.Lamp housing 1 comprises lamp housing 7 and is fixedly connected on the following lamp housing 8 of lamp housing 7 bottoms.The internal face of last lamp housing 7 is that section is half elliptic hemisphere face.That is to say the hemisphere face of the similar rugby of internal face of last lamp housing 7.The section of lamp housing 7 internal face central points is half elliptic on the process.The internal face of following lamp housing 8 is annular cambered surface.The section of following lamp housing 8 internal faces be two symmetrically and be half elliptic camber line.The major axis of last lamp housing 7 internal face sections is greater than the major axis of following lamp housing 8 internal face sections, and the minor axis of last lamp housing 7 internal face sections is greater than the minor axis of following lamp housing 8 internal face sections.Lampshade 2 is fixedly connected on down the bottom of lamp housing 8.Lamp housing 1 and lampshade 2 form closed cavity.Reflecting layer 3 is fixedly connected on the inwall of lamp housing 1.Cooling base 5 is fixedly connected on down on the inwall of lamp housing 8.LED light emitting module 4 is fixedly connected on the cooling base 5.LED light emitting module 4 ringwise, LED light emitting module 4 is along following lamp housing 8 circumferential arrangement.This can make LED light emitting module 4 send more rays.Driver 6 is fixedly connected on the lamp housing 1, and driver 6 electrically connects with LED light emitting module 4.
Further, the minor axis of lamp housing 8 sections and the ratio of major axis under the minor axis of described upward lamp housing 7 sections and the ratio of major axis equal, and this ratio a satisfies: 0.1≤a＜1.The light of the last lamp housing 7 that this ratio arranges and 8 reflections of following lamp housing is all bigger with the light of following lamp housing 8 reflections than the last lamp housing 7 that other ratios arrange.This is conducive to strengthen the light efficiency of light fixture.
Further, described reflecting layer 3 is covered with the whole inwall of lamp housing 1.The mounting means of reflector layer 3 has multiple, the preferred two kinds of mounting means of this patent.First kind of mode is: described reflector layer 3 is sheet, is bonded on the inwall of lamp housing 1.The second way is: described reflector layer 3 is coating, is coated on the inwall of lamp housing 1.Lampshade 2 is passed in reflecting layer 3 reflections of the light that LED light emitting module 4 sends through being located at down lamp housing 8 inwalls or going up lamp housing 7 inwalls at last, is mapped to the outside.When reflecting layer 3 is covered with the whole inwall of lamp housing 1, more rays is reflexed on the lampshade 2.
Further, in the section of described lamp housing 1, the perpendicular bisector of two major axis that following lamp housing 8 is symmetrical intersects at the mid point of lamp housing 7 internal faces.This makes the light of going up lamp housing 7 reflections reach maximum.
Further, described cooling base 5 is positioned at the down center of lamp housing 8 walls, cooling base 5 ringwise, and along the circumferential arrangement of lamp housing 8 down.Because LED light emitting module 4 is fixed on the cooling base 5, so cooling base 5 is positioned at the center of lamp housing 8 walls down, can make down the light of lamp housing 8 reflections reach maximum.Cooling base 5 is conducive to heat radiation ringwise.In addition, LED light emitting module 4 also ringwise, LED light emitting module 4 is along the following circumferential arrangement of lamp housing 8.LED light emitting module 4 is fixedly connected on the cooling base 5.
Further, described upward lamp housing 7, following lamp housing 8 and cooling base 5 are monolithic construction.Adopt monolithic construction, effectively reduced the thermal contact resistance between lamp housing 1 and the cooling base 5, be conducive to the heat radiation of LED light emitting module 4.
Further, be provided with cavity between the outside wall surface 102 of described lamp housing 1 and the internal face 101, driver 6 is arranged in this cavity, and driver 6 is fixedly connected on the wall of chamber.As shown in Figure 1, this cavity is arranged in the wall of lamp housing 7, and driver 6 is arranged in the cavity of lamp housing 7.As shown in Figure 2, this cavity is arranged in the wall of lamp housing 8 down, and driver 6 is arranged in the cavity of lamp housing 8 down.Driver 6 is located in the cavity of lamp housing 1, is conducive to protect driver 6, be not subjected to the attractive in appearance of the influence of external environment and light fixture.
The course of work of the integrated high light efficiency LED light fixture of said structure is: start driver 6, LED light emitting module 4 is luminous.A part of light in the light that LED light emitting module 4 penetrates is mapped to the reflecting layer on lamp housing 7 inwalls, and the reflecting layer of going up then on lamp housing 7 inwalls directly is mapped to light on the light shield 2, and light passes light shield 2, penetrates light fixture.Another part light that LED light emitting module 4 penetrates is through the reflecting layer of the reflective layer reflects on lamp housing 8 inwalls down to last lamp housing 7 inwalls, and the reflecting layer of going up then on lamp housing 7 inwalls is mapped to this part light on the light shield 2, passes lampshade 2 at last and is mapped to the outside.
The integrated high light efficiency LED light fixture of this structure by at following lamp housing 8 inwalls ringwise LED light emitting module 4 being set, has increased the intensity of light.By shape and the position in lamp housing 7, following lamp housing 8 and reflecting layer 3 rationally are set, the internal face of last lamp housing 7 is that section is half elliptic hemisphere face, the internal face of following lamp housing 8 is annular cambered surface, reflecting layer 3 is positioned at the inwall of lamp housing 7 and following lamp housing 8, and LED light emitting module 4 is installed in down the center of the inwall of lamp housing 8, the light portion that makes LED light emitting module 4 send is directly injected in the reflecting layer of lamp housing 7, penetrates lampshade 2 then, reduce the order of reflection of light, strengthened light efficiency.Simultaneously, after the remainder light that LED light emitting module 4 sends is injected down the reflecting layer of lamp housing 8, can inject again in the reflecting layer of lamp housing 7, then penetrate lampshade 2.That is to say that whole light that LED light emitting module 4 sends all can penetrate lampshade 2.This has also strengthened light efficiency.
Below only be the example of implementing the technical program, those skilled in the art do not need to pay any creative work under the enlightenment of technique scheme, to the improvement that the technical program is carried out, all belong to the protection domain of this patent.
