The first light emitting surface 130 of the first light emitting unit 13 faces the inside of the first accommodating case 11, so that the light emitted therefrom can enter from the first light incident surface 121 of the first light guiding unit 12 and exit from the first light exiting surface 123 of the first light guiding unit 11. The first welding portion 132 is exposed to the first accommodating casing 11, that is, the first welding portion 132 is exposed to the other end of the channel 110 of the first accommodating casing 11, for example, the bottom surface of the first accommodating casing 11. In other embodiments, the first surface mount light emitting module 1a may be used independently (see fig. 7), or a plurality of first surface mount light emitting modules 1a may be connected in parallel to form a multi-channel surface mount light emitting module in a first-order array arrangement along the horizontal direction, as will be described in detail later.

232 and 132 can be flatly attached to the circuit board pads (not shown in the drawings) and have good soldering condition. The second light emitting surface 230 of the second light emitting unit 23 faces the inside of the second accommodating case 21, so that the light emitted by the second light emitting surface 230 can enter through the second light incident surface 221 of the second light guiding unit 22 and be emitted out through the second light emitting surface 223 of the second light guiding unit 22.

The first surface mount light emitting module 1a and the second surface mount light emitting module 2a have substantially similar compositions, and each include a receiving case (11, 21), a light guide unit (12, 22), and a light emitting unit (13, 23). The difference between the two light guide units is that the shapes and structures of the two light guide units (12, 22) can be the same or different, in addition, the shapes of the two accommodating shells (11, 21) are different and can be combined with each other, and moreover, the two light emitting units (13, 23) can be the same color or different colors, which is described in detail later.

The internal structure of the first surface mount light emitting module 1a will be exemplified below. The inner side surfaces of the first side walls 112 respectively form a continuous or discontinuous first bearing portion 113, and the first bearing portions 113 together define a first bearing surface 1130 located on the same plane, so that the first light emitting unit 13 can be stably and accurately abutted against the first accommodating housing 11. In other words, the first light emitting unit 13 and the first receiving housing 11 are coupled to each other and can abut against the first bearing surface 1130. The inner side surface of the first sidewall 112 is further formed with a first glue containing portion 115, and the first glue containing portion 115 is recessed and located between the first bearing surface 1130 and the bottom edge of the first sidewall 112 and faces the side surface of the first light emitting unit 13. The first glue containing portion 115 is used for containing glue (not shown), so as to increase the bonding force between the first light emitting unit 13 and the first containing shell 11, and the first light emitting unit 13 can be better bonded to the first containing shell 11. In the present embodiment, the first glue receiving portion 115 is defined by a plurality of protruding strips 1151, and the protruding strips 1151 are perpendicular to the first bearing surface 1130 to form a plurality of glue receiving grooves. In other embodiments, the width of each rib 1151 decreases from the first bearing surface 1130 toward the bottom edge of the first sidewall 112. However, the number and structure of the first glue receiving portions 115 are not limited thereto.

However, this disclosure is not limited thereto, as in other embodiments, the positioning protrusions 1122 can be omitted or replaced with other positioning snaps. In addition, the outer surface of the first accommodating casing 11 has a clamping portion 1121 and a clamping groove 1120, and the clamping portion 1121 or the clamping groove 1120 can be used to clamp a clamping groove or a clamping portion of an accommodating casing of another surface mount light emitting module (see fig. 6A). Specifically, the locking portion 1121 and the locking groove 1120 are a dovetail protrusion and a dovetail groove, respectively. However, the present application is not limited thereto, the number of the clamping portion and the clamping groove may be at least one, and the clamping portion and the clamping groove may also be clamping structures of other shapes, for example, the clamping portion may be a convex portion structure, and the clamping groove may be a groove structure, and the shapes and structures are not limited as long as the function of mutual assembling and jointing is achieved.

The light emitted by the first light emitting unit 13 can enter the incident surface 121 of the first light guiding unit 12, and is reflected by the reflecting surface 122 and then emitted through the light emitting surface 123. In other embodiments, the slope 117 may have a reflective function, but the present application is not limited thereto. In addition, as shown in fig. 6B, the overall thickness T of the first light emitting unit 13 is greater than or equal to the height H from the bearing surface 1130 to the bottom edge of the sidewall 112.

In other embodiments, the width of each protruding bar 2151 can gradually decrease from the second bearing surface 2130 toward the bottom edge of the second sidewall 212. However, the number and structure of the second glue receiving portions 215 are not limited thereto.
