Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 and Fig. 2, the light output arrangement 10 that first embodiment of the invention provides comprises pedestal 11, optical waveguide 12, two light sources 13 and substrates 14.
Certainly, also can omit substrate 14, but optical waveguide 12 is directly fixed on pedestal 11 with the second bonding coat 16.
Optical waveguide 12 comprises the first subchannel 121, the second subchannel 122, main channel 123, be positioned at the light inlet 124 on the first subchannel 121 and the second subchannel 122 and light-emitting window 125, the first subchannels 121 that are positioned on main channel 123 are connected with main channel 123 with the second subchannel 122.The distance at the first 121 center, subchannel and 123 centers, main channel equals the distance at the second 122 center, subchannel and 123 centers, main channel, and the first subchannel 121 and the second 123 center, 122Yi main channel, subchannel are that axle is symmetrical.
The first subchannel 121 comprises the first connected straight section 1211 and the second straight section 1212, the second subchannel 122 comprises the 3rd connected straight section 1221 and the 4th straight section 1222, the first straight section 1211 is parallel with the 3rd straight section 1221, light inlet 124 is positioned on the first straight section 1211 and the second straight section 1212, the second straight section 1212 intersects and is connected with main channel 123 with the 4th straight section 1222, and light-emitting window 125 is positioned at one end away from the second straight section 1212 and the 4th straight section 1222, main channel 123.
A correspondence the first subchannel 121 in two light sources 13, and corresponding the second subchannel 122 of another one, and light source 13 is aimed at light inlet 124, so that the light that light source 13 sends enters the first subchannel 121 and the second subchannel 122 through light inlet 124, then in main channel 123, carry out superposition, light after superposition is from light-emitting window 125 outgoing, carries out superposition, thereby make emergent light have higher output power due to what two light sources 13 sent in optical waveguide 12.
While making light output arrangement 10, first light source 13 is fixed on pedestal 11 by resisting mediums such as glue, then optical waveguide 12 is arranged on the second surface 141 of substrate 14, between the 3rd surface 142 and the first surface 111 of pedestal 11, the second bonding coat 16 is set so that substrate 14 is fixed on pedestal 11, now, if the height of the exiting surface of light source 13 (and distance) between pedestal 11 is greater than the first subchannel 121, the height (distance between center and pedestal 11) of the second subchannel 122, can be by the thickness of increase the second bonding coat 16 so that highly identical, thereby guarantee that the fairing profit that light source 13 sends is coupled into optical waveguide 12, or, do not change the thickness of the second bonding coat 16, height between exiting surface and the pedestal 11 of reduction light source 13, thus the height that storage tank reduces between light sources 13 and pedestal 11 to hold light source 13 is set on pedestal 11, to guarantee that the fairing profit that light source 13 sends is coupled into optical waveguide 12.
As shown in Figure 3, the light output arrangement 20 that second embodiment of the invention provides comprises pedestal 21, is positioned at optical waveguide 22 and three light sources 23 on pedestal 21.
The structure of the structure of optical waveguide 22 and optical waveguide 12 is basic identical, difference is: optical waveguide 22 comprises the first subchannel 221, the second subchannel 222, the 3rd subchannel 223 and main channel 224, the first subchannel 221, the second subchannel 222 and the 3rd respectively corresponding light source 23 in subchannel 223, optical waveguide 22 is directly arranged on pedestal 21 with a bonding coat.
Certainly, optical waveguide 22 also can be arranged on substrate, and then is arranged on pedestal 21 by bonding coat.
The first subchannel 221, the second subchannel 222 are connected with main channel 224 with the 3rd subchannel 223, and the center superposition of the second 222 center, subchannel and main channel 224, and the first subchannel 221 and the 3rd subchannel 223 are take the second subchannel 222 as axle is symmetrical.
In other embodiment, the number of light source 13 can be done suitably to change according to output power, for example, can be 4,5 etc.Certainly, while there is conversion in the number of light source 13, also respective change of the subchannel of optical waveguide 12: the number of subchannel equals the number of light source so that all corresponding subchannel of each light source.
Be understandable that, those skilled in the art also can do other and change in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
