## Abstract

An LED light source module includes a substrate; a protective layer disposed on the substrate and having at least one opening; a plurality of conductive terminals disposed in the at least one opening, a light-emitting member, a plurality of electrodes, and an auxiliary structure. The conductive terminals include a first conductive terminal and a second conductive terminal. The light-emitting member includes a bottom surface, a light-emitting surface connected to the bottom surface, a back surface opposite to the light-emitting surface, at least one lateral surface connecting the light-emitting surface and the bottom surface. The auxiliary structure includes a main support portion provided on the substrate to support the bottom surface of the light-emitting member, and the main support portion is located between the electrodes and extends at least from the back surface to the light-emitting surface of the light-emitting member.

## Claims

### Claim 1

An LED light source module, comprising:
a substrate;
a protective layer, disposed on the substrate and having at least one opening;
a plurality of conductive terminals, arranged in the at least one opening;
a light-emitting member, including a bottom surface, a first lateral surface connected to the bottom surface, a second lateral surface connected to the bottom surface and opposite to the first lateral surface, and a plurality of electrodes, wherein the electrodes are electrically connected to the conductive terminals respectively; and
an auxiliary structure, including at least two interposed portions arranged between the substrate and the light-emitting member, wherein the interposed portions correspond to the first lateral surface and the second lateral surface of the light-emitting member respectively.

### Claim 2 (depends on 1)

The LED light source module as claimed in claim 1, wherein the light-emitting member includes a light-emitting surface, the light-emitting surface is located between the first lateral surface and the second lateral surface, and the light-emitting surface is connected to the bottom surface.

### Claim 3 (depends on 2)

The LED light source module as claimed in claim 2, wherein the electrodes are located on the bottom surface of the light-emitting member, the interposed portions are located outside of the electrodes, at least a part of one of the interposed portions is located between the electrodes and the first lateral surface of the light-emitting member, and at least a part of the other one of the interposed portions is located between the electrodes and the second lateral surface of the light-emitting member.

### Claim 4 (depends on 1)

The LED light source module as claimed in claim 1, wherein the first lateral surface is a light-emitting surface, the second lateral surface is a back surface of the light-emitting member opposite to the light-emitting surface, and both the light-emitting surface and the back surface are connected to the bottom surface.

### Claim 5 (depends on 4)

The LED light source module as claimed in claim 4, wherein one of the interposed portions is provided on the substrate and located between the electrodes and the light-emitting surface of the light-emitting member.

### Claim 6 (depends on 4)

The LED light source module as claimed in claim 4, wherein one of the interposed portions is provided behind the electrodes and extends in a direction away from the light-emitting surface of the light-emitting member.

### Claim 7 (depends on 1)

The LED light source module as claimed in claim 1, wherein the interposed portions are provided on the substrate.

### Claim 8 (depends on 1)

The LED light source module as claimed in claim 1, wherein the interposed portions are located between the electrodes and an outer periphery of the light-emitting member.

### Claim 9 (depends on 1)

The LED light source module as claimed in claim 1, wherein the interposed portions are arranged symmetrically or parallelly.

### Claim 10 (depends on 1)

The LED light source module as claimed in claim 1, wherein the interposed portions surround the conductive terminals with a non-enclosed shape to define a passway.
