Description
Technical field
The present invention is about a kind of lighting device, and especially in regard to a kind of lighting device of integrating the multi-disc LGP.
Background technology
Figure 1A is a kind of part sectioned view of existing lighting device, and Figure 1B is lighting device vertical view behind the frame before removing of Figure 1A.Please also refer to Figure 1A and Figure 1B, existing lighting device 100 comprises a LGP 110, a plurality of first light-emittingdiode 120, a plurality of second light-emittingdiode, 130, one a preceding frame 140 and lamp box 150.Lamp box 150 has a base plate 152 and a plurality of side plate 154 that is connected to base plate 152.LGP 110 has the second surface 114 of a first surface 112, a relative first surface 112 and connects the incidence surface 116,118 of first surface 112 and second surface 114, and wherein incidence surface 116 is with respect to incidence surface 118.
LGP 110 is disposed on the base plate 152.First light-emittingdiode 120 and second light-emittingdiode 130 are configured in respectively in the lamp box 150, and are positioned on the two relative side plates 154.First light-emittingdiode 120 is suitable for towards incidence surface 116 luminous, and second light-emittingdiode 130 is suitable for towards incidence surface 118 luminous.The light that first light-emittingdiode 120 and second light-emittingdiode 130 are sent can enter the LGP 110 from incidence surface 116 and incidence surface 118 respectively, and is passed to outside the LGP 110 via first surface 112, to form area source.Preceding frame 140 is disposed on the lamp box 150, and covers the edge of first light-emittingdiode 120, second light-emittingdiode 130 and LGP 110.
In order to make lighting device 100 can be connected to domestic power supply, to order about first light-emittingdiode 120 and second light-emittingdiode 130 is luminous, the outside of lamp box 150 needs with external one drive circuit plate of circuit and AC/DC power converter.Yet, be disposed at the drive circuit board of lamp box 150 outsides and the outward appearance that the AC/DC power converter can influence lighting device 100, and when installing and use easily because of circuit being come off cause drive circuit board and AC/DC power converter to drop and damaging.
In addition, existing lighting device 100 adopts the LGP 110 of monolithic.When user's demand was large-area area source, LGP 110 must enlarge, and caused the preponderance of monolithic LGP 110, and this can cause cost to rise, and made the preponderance of lighting device 100 and be difficult for carrying.
Moreover, refer again to Figure 1A, first light-emittingdiode 120 and second light-emittingdiode 130 all are configured on the side plate 154 of lamp box 150.When first and second light-emittingdiode 120,130 is luminous, can produce heat H simultaneously.Yet, in existing lighting device 100, the heat H that light-emittingdiode 120,130 is produced is after conducting to side plate 154, the top 154a of side plate 154 can be run into when up conducting and conduction can't be continued, therefore heat only can down conduct, could continue to conduct to the base plate 152 that is connected with side plate 154, and then dissipate in the air.Because the hot H that light-emittingdiode 120,130 is produced only has the down approach of conduction, this can make the radiating efficiency of light-emittingdiode 120,130 relatively poor, and then has influence on the luminous efficiency and the service life of light-emittingdiode 120,130.
