2. LED wafer module can also be as shown in Figure 4, Figure 5, for sending the holistic LED wafer of the list module of red, green, blue three primary colours light, this LED wafer module also comprises red, green, blue three-primary color LED wafer 1, and the LED wafer 1 of each color is at least provided with a slice, all LED wafers 1 or serial connection, or and connect, or string and elder brother connect rear being jointly fixedly arranged on same metal substrate 2.In the present embodiment, three colors have respectively provided a slice, and the anode of three LED wafers and negative electrode are connected in series successively.
The same metal aluminum substrate that adopts of described metal substrate 2, fixedly draws two metal electrodes 3 by plastic packaging layer 5 plastic packaging equally, and all LED wafers 1 are connected with external power source by metal electrode 3.And for the module that LED wafer 1 is formed is fixed on metal substrate 2, the module surface forming at all LED wafers 1 equally scribbles one deck external sealant 4, the module that LED wafer 1 is formed is fixed on same metal substrate 2.
(2) photic zone 30
Photic zone 30 is launched for R, G, B three primary colours that LED lighting means 10 is sent.Photic zone 30 in the present embodiment adopts silicone grease glue material, as shown in Fig. 2-1,2-2,4,6,7,8,9, be coated with one deck silicone grease glue in the output cross section of fibre circuit 20, then through hot setting, when coating silicone grease glue, can be applied as required plane or sphere, the size of silicone grease glue will be determined according to the size in terminal cross section.
(3) fibre circuit 20
The complex light that fibre circuit 20 produces for R, G that LED lighting means 10 is sent, B three primary colours mixed light is sent to photic zone 30 and launches.Because LED lighting means 10 forms in the present embodiment are different, therefore, the setting of fibre circuit 20 is also different, for Fig. 2-1, Fig. 2-2, LED lighting means 10 in Fig. 3, because every LED wafer 1 is fixedly arranged on separately on a metal substrate 2, therefore, the luminous end of each LED wafer 1 is all provided with a fibre circuit 20 by optical fiber fixed terminal 21, in Fig. 2-1, formed by single jumbo fiber respectively, three fibre circuit 20 ends pool a total fibre circuit 200 by optical fiber Converting terminal 23, total fibre circuit 200 is provided with photic zone 30 in one end that optical fiber Converting terminal 23 is not set, the fibre bundle that adopts multifiber to form in Fig. 2-2 forms, and the fibre bundle of three fibre circuits 20 forms a jumbo fiber after evenly mixing (red, green, blue three looks combine in order), is provided with photic zone 30 in the jumbo fiber cross section forming
And for the LED lighting means 10 in Fig. 4, Fig. 5, because three LED wafers 1 are located on same metal substrate 2 jointly, therefore, only need a fibre circuit 20, one end of described fibre circuit 20 is fixedly arranged on metal substrate 2 by optical fiber fixed terminal 21, and the other end is directly coated with photic zone 30.
In addition, according to photic zone 30 shapes, match with the shape of fibre circuit 20 terminations of its coating, it is the termination of difformity fibre circuit 20, corresponding difform photic zone 30, can make the present embodiment different angles transmitted light, for example, in Fig. 6, the termination that fibre circuit 20 is coated with photic zone 30 is the plane of vertical fiber circuit 20 axis, now, the present embodiment transmission be horizon light, and Fig. 7, in Fig. 9, to be coated with the termination of photic zone 30 be spherical (because Fig. 9 adopts single jumbo fiber to fibre circuit 20, while setting, jumbo fiber is provided with to one end shrinking of photic zone 30, and be applied as and the sphere of jumbo fiber coaxial line), the present embodiment transmission is high brightness point light, and in Fig. 8, the termination that fibre circuit 20 is coated with photic zone 30 is inclined-plane, therefore, the light of final transmission is side light source.
Because the three primary colours of sending by RGB three-primary color LED chip in the present embodiment produce complex light by optical fiber mixed light, do not use fluorescent material, the LED that there will not be fluorescent material coking and cause shortens service life, the phenomenons such as brightness decay, and the complex light colored gamut that the present embodiment produces is wider, colourity is more even, and colour gamut, colourity is easy to control simultaneously, the shape of transmission layer 30 can be spherical, plane, the various shapes such as inclined-plane, therefore the high brightness complex light that the present embodiment can outgoing different angles, can meet projector light source domain, image shows the demand of field and each lighting field, make the range of application of the present embodiment more extensive.
