In addition, in the present embodiment, this one of them plate face 628 is to be designed to a plane, and another plate face 629 is that the rightabout towards this one of them plate face outwards protrudes out and presents arc.By this luminescence component 90 be incident in this light guide body 62 part light can via these arc face 629 bright dippings and, this arc face 629 is a concave surface compared to the light of these light guide body 62 inside, light is equal to concavees lens by its effect; Therefore, be to be divergent shape by the light of these arc face 629 bright dippings, to enlarge the rising angle of light.
Again, this another plate face 628 with respect to this circular arc plate face 629 can be provided with a reflection subassembly (figure does not show), being incident in this light guide body 62 but by excessive these light guide body 62 inside of light reflected back of this plate face 628, to promote the light service efficiency of this lighting module integral body 60 by this luminescence component 90.
Cooperate and to consult Fig. 9, be the stereogram of the lighting module of eighth embodiment of the invention.This lighting module 60 ' of this lighting module comprises a leaded light component 61 ' and at least one luminescence component 90, this leaded light component 61 ' comprises a light guide body 62 ', and this light guide body 62 ' has an incidence surface 620 ', a rear end face 622 ', one first side 624 ', one second side 626 ' and two plate faces 628 ', 629 '.This first side 624 ' has one first angle θ 1 by this incidence surface 620 ' towards the direction in contrast to this second side 626 ' and tilts, and be adjacent to this rear end face 622 ', this second side 626 ' has one second angle θ 2 by this incidence surface 620 ' towards the direction in contrast to this first side 624 ' and tilts, and is adjacent to this rear end face 622 '.In the present embodiment, this first angle θ 1 equals this second angle θ 2, and this light guide body 62 ' is extended towards the outside convergent of this rear end face 622 ' direction ground by this incidence surface 620 '.Therefore, the light of avoiding being incident in this light guide body 62 ' by this luminescence component 90 constantly in this first side 624 ' and this second side 626 ' produce total internal reflection, to promote the rising angle of this lighting module 60 '.
Again, this one of them plate face 628 ' is to be designed to a plane, and another plate face 629 ' is that the rightabout towards this one of them plate face outwards protrudes out and presents arc.Therefore, the a part of light that is incident in this light guide body 62 ' by this luminescence component 90 is can be via the plate face 629 ' bright dipping of this arc, because this arc shape board face 629 ' is a concave surface compared to the light of this light guide body 62 ' inside, light is equal to concavees lens by its effect, therefore, light by this arc shape board face 629 ' bright dipping is to be divergent shape, can promote the rising angle of light significantly.
Again, another plate face 628 ' with respect to this arc 629 ' plate face more can be provided with a reflection subassembly (figure does not show), being incident in this light guide body 62 ' but by excessive this light guide body 62 ' inside of light reflected back of this plate face 628 ', to promote the light service efficiency of this lighting module integral body 60 ' by this luminescence component 90.
Cooperate and to consult Figure 10, be the cutaway view of the lighting module of ninth embodiment of the invention.This lighting module 70 comprises a leaded light component 71 and at least one luminescence component 90, and this leaded light component 71 includes a light guide body 72.The lighting module 70 of present embodiment is roughly similar to above-mentioned the 7th embodiment and the 8th embodiment, its difference is, a wherein plate face 728 of this light guide body 72 is for being made up of a plurality of micro-structurals 729, and is adjacent to one of this light guide body 72 incidence surface 720, a rear end face 722, one first side 724 and one second side 726.This plate face 728 with those micro-structurals 729 is to make outgoing be divergent shape in the light of this plate face 728, to enlarge the rising angle of the light that to be located at this plate face 728 effectively.
In addition, side is to be provided with a reflection subassembly (figure does not show) outside this another plate face 728, being incident in this light guide body 72 but by excessive these light guide body 72 inside of light reflected back of this another plate face 728, to promote the light service efficiency of these lighting module 70 integral body by this luminescence component 90.
The present invention's leaded light component is to see through this first side and this second side that this tilt this first angle θ 1 and this second angle θ 2 are adjacent to this incidence surface and this rear end face, with reach the light avoiding being incident in this light guide body by this luminescence component constantly in this first side and this second side produce total internal reflection, and then enlarge the rising angle of this leaded light component.
Right the above, only be the present invention's preferred embodiment, when the scope that can not limit the invention process, promptly all equalization of doing according to the present patent application claim change and modification etc., all should still belong in the protection category that claim covering scope of the present invention is intended to.
