Described LED light module 2 comprises a substrate 21, multiple LED chip 22 and colloid 23; Aforesaid substrate 21 has front 211 and the back side 212 being positioned at two opposite sides, and the back side 212 of substrate 21 is installed on the first surface 11 of circuit board 1; Multiple LED chip 22 is installed on the front 211 of substrate 21, and these LED chips 22 are electrically connected with circuit board 1 via substrate 21.
Wherein, described LED chip 22 is arranged at the spread configuration of arrangement mode roughly in matrix type in the present embodiment on circuit board 1.And about the connected mode between above-mentioned LED chip 22 and circuit board 1, can be connect (wire bonding) by routing or cover brilliant connection (flip chipbonding), do not limited at this.Moreover, described LED chip 22 in the present embodiment can be White-light LED chip, red LED chip, green LED chip, blue-light LED chip, infrared LEDs chip and ultraviolet LED chip at least one of them, but not as limit.
LED chip 22 on the front 211 that described colloid 23 is positioned at substrate 21 and on coated substrate 21, above-mentioned colloid 23 has the exiting surface 231 away from substrate 21, and exiting surface 231 is recessed is formed with several crisscross grooves 232.Wherein, the orthogonal projection of every bar groove 232, in the view field in substrate 21 front 211, is positioned at the position that substrate 21 front 211 is not provided with these LED chips 22.Moreover, recessedly on each edge of described exiting surface 231 be formed with a unfilled corner 233, above-mentioned groove 232 be positioned at these unfilled corners 233 around scope.And in the wantonly two adjacent LED light module 2 of LED luminous plaque 100, its unfilled corner 233 connected on edge is spliced into a combined type groove 234 jointly.Wherein, the hierarchy structure of any combination formula groove 234 is roughly equal to the hierarchy structure of arbitrary groove 232 in the present embodiment, and arbitrary unfilled corner 233 width in combined type groove 234 is preferably the half of groove 232 width, but is not limited to this.And any combination formula groove 234 be also roughly parallel to these grooves 232 at least one of them.

Say further, the colloid 23 of the present embodiment can be entirely for printing opacity colloid (as shown in Figure 4) or include a multiple printing opacity colloid 23a and shading colloid 23b (as shown in Figure 5).Specifically, in the example formed for printing opacity colloid 23a and shading colloid 23b at colloid 23, described printing opacity colloid 23a is attached to the front 211 of substrate 21 and is coated on these LED chips 22 respectively with being intervally installed.Wherein, described printing opacity colloid 23a is after LED chip 22 is installed on the front 211 of substrate 21 in the present embodiment, and direct forming is on the front 211 of substrate 21, and that is, the printing opacity colloid 23a of the present embodiment is an optical lens of LED chip 22.The corresponding relation of described printing opacity colloid 23a and LED chip 22 is single to list, and printing opacity colloid 23a intactly coated LED chip.
In more detail, each printing opacity colloid 23a includes an a top exiting surface 231a and ring side 232a, and pushes up the light-emitting area (end face as the LED chip 22 in Fig. 5) that exiting surface 231a corresponds to the coated LED chip 22 of printing opacity colloid 23a.That is, the light-emitting area of described LED chip 22 is positions within the region that top exiting surface 231a is formed towards front 211 orthogonal projection of substrate 21.Moreover being coated on the light that the LED chip 22 in each printing opacity colloid 23a sends is penetrated in outward by top exiting surface 231a.
