Embodiment
Advantages of the present invention is expanded on further below with reference to specific embodiment and accompanying drawing.
As shown in Figures 1 and 2, light fixture 1 of the present invention, including circular lamp socket 10, some masters for being sticked with the periphery of lamp socket 10
Lamp source 11, the guiding device 12 for being located on the periphery of lamp socket 10 and receiving the light launched from king light source 11, fix with lamp socket 10
Connect and lamp socket 10 and guiding device 12 are fixed on the support member 13 of installation foundation 15 and the periphery of support member 13 is located on
Back lighting device 14.The king light source 11 is some LED lamp sources.In the preferred embodiment for the present invention, the installation foundation 15
For ceiling, but in other preferred embodiments, the installation foundation is not limited to ceiling, can make to be that other need to install
The place of light fixture of the present invention.
Guiding device 12 is arranged at the periphery of lamp socket 10 i.e. around lamp socket 10, and king light source 11 is attached at the periphery of lamp socket 10, and leads
Lamp source 11 is fixed on lamp socket 10 simultaneously.In other preferred embodiments, lamp socket 10 can have other moulding, such as square
Body, cuboid etc..Now, back lighting device 14 is still located on the top face of lamp socket 10, and main light source 11 can be attached at lamp socket 10
Side, guiding device 12 around lamp socket 10 side set.LED drives and supply line（It is not shown）Lamp socket can be arranged at
In 10.When king light source 11 lights, guiding device 12 can receive the illumination that king light source 11 is sent, and to external diffusion, preferably lead
Electro-optical device 12 could be arranged to be located on lamp socket 10 and the periphery of king light source 11, and be annular shape, so not only act as aesthetic,
Can make simultaneously more uniform peace that illumination light dissipates and.
The cross-sectional view of one embodiment of the invention is illustrated in figure 2, because king light source 11 is arranged at the periphery of lamp socket 10, its
The illumination sent mainly line source, but in order to preferably play illuminating effect, can be effective by adding guiding device 12
Line source is transformed into area source.Guiding device 12 includes light guide plate 121, and king light source 11 faces the side of light guide plate 121, its
The line source sent laterally enters light guide plate 121 and the mesh point in the altitude range of light guide plate 121 after refraction again through its setting
By light dispersion it is uniform after, line source can be transformed into uniform area source.Then the area source is again by the outer cladding of light guide plate 121
Layer of transparent protective cover 122 further homogenize, realize preferable lighting effect.The protective cover 122 can be protected effectively
Tabula rasa 121 is protected and led, prevents it from being damaged under external force.Because the transparent protective shield 122 needs transmitted ray, so general from modeling
Material or glass, in a special case, transparent protective shield 122 can select atomization glass, the light that such king light source 11 is projected
Line can seem softer via light guide plate 121, then by the light projected after transparent protective shield 122, obtain more preferable Environmental Effect
Really, atmosphere is effectively built.
In the present embodiment, back lighting device 14 is located on the periphery of support member 13 and positioned at the back side of lamp socket 10, and it is mainly used in
Produce backlight.The back lighting device 14 includes at least one lamp source 141 and refracting means 142.Secondary lamp source 141 is fixed on refraction
The top of device 142 is simultaneously located on the periphery of support member 13.In other embodiment, secondary lamp source 141 can be imitated according to backlight
There are a variety of arrangement modes the need for fruit.Support member 13 is also connected with installation foundation 15 simultaneously.Because guiding device 12 is transparent
, it is possible to see the backlight that the secondary lamp source 141 of the behind of lamp socket 10 is sent.Being additionally, since support member 13 has necessarily
Highly, it is preferred that the distance between the support member 13 and installation foundation 15 are more than 10cm so that backlight effect is more preferable.Secondary lamp
The background light sent on source 141 will be by guiding device 12 to external exposure.So looked up from transparent guiding device 12
Go, the light that the light and king light source 11 that secondary lamp source 141 is launched are launched can just be superimposed, and build more preferable light
Effect.In other preferred embodiments, backlight can be only visible by transparent guiding device 12, and is not involved in and key light
The superposition of the light in source 11.
It is preferred that, the problem of due to refraction angle, the light that secondary lamp source 141 is sent can not directly form uniform backlight
Effect, so can effectively utilize the light of time lamp source 141 by the structure changed in refracting means 142.Refracting means 142
Including be available for secondary light source 141 arrange horizontal refraction device top surface 1423, be partly sticked and around the periphery of support member 13 and in
The reflecting surface 1421 that extends between the top surface of above-mentioned refracting means top surface 1423 and lamp socket 10 and from above-mentioned top surface outer rim to lamp socket
10 top surface extends the exiting surface 1422 to be formed.Above-mentioned refracting means top surface 1423, reflecting surface 1421 and exiting surface 1422 enclose and set
It is formed with light mixing chamber.Reflecting surface 1421 is the concave surface of an arc, and the light part that secondary lamp source 141 is sent is directly by exiting surface
1422 transmissions a, part is irradiated to reflecting surface 1421 and then the backlight being refracted at exiting surface 1422, therefore exiting surface 1422
Effect is uniform attractive in appearance.In other preferred embodiments, the optical components such as lens can also be set to realize to secondary light source 141
Light efficiency control.Now, through transparent guiding device 12, backlight effect is visible.Reflecting surface 1421 and exiting surface
1422 can each be individually present or while use cooperatively, it may occur to persons skilled in the art that, when reflecting surface 1421
When being used cooperatively with exiting surface 1422 simultaneously, the light that more effectively can be sent secondary lamp source 141 is pooled to guiding device 12
On.
In the present embodiment, king light source 11 can use LED, due to LED small volumes, can make the thickness of guiding device 12
Degree equally diminishes, and reduces the volume of whole light fixture, and the space in the room of saving, same secondary lamp source 141 also uses LED, equally
The purpose for the volume for reducing whole light fixture can be reached.And the use of king light source 11 can send the LED of color variable light, by
Outside control turn colors, equally, the secondary use of lamp source 141 can send the LED of color variable lamp source, and face is converted by outside control
Color, when king light source 11 and time lamp source 141 while when using the LED of color variable lamp source, can control, adjust by the way that reception is outside
Different colors, or with time auto-changing color.
It should be noted that embodiments of the invention have preferably implementation, and any type of not is made to the present invention
Limitation, any one skilled in the art changes or is modified to possibly also with the technology contents of the disclosure above equivalent effective
Embodiment, as long as without departing from the content of technical solution of the present invention, what the technical spirit according to the present invention was made to above example
Any modification or equivalent variations and modification, in the range of still falling within technical solution of the present invention.
