A kind of LED module of improvement
This utility model relates to LED field technology, refers in particular to the LED module of a kind of improvement.
Modern society increasingly payes attention to the different-effect of the word that advertisement indicates, some use rainbow lamp-based in the shop front, has
Using lamp box, some use luminescent characters, traditional luminescent characters has top shell, drain pan and is installed in the LED light in top shell and drain pan
Source, its volume is relatively big, and parts are many, assembles trouble, and unsightly, and water proofing property is bad for outward appearance.Therefore, it is necessary to current
Luminescent characters improves.
Utility model content
In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of improvement
LED module, its can effectively solve existing luminescent characters volume compared with big, parts are many, assemble trouble, outward appearance unsightly and is prevented
The problems such as aqueous is bad.
For achieving the above object, this utility model uses such as purgation technical scheme:
The LED module of a kind of improvement, includes pcb board and moulding；LED, pcb board it is provided with on this pcb board
Two ends be respectively connected with positive lead and negative lead, this moulding is fixed together with pcb board produced by insert molding, moulding
Wrapping pcb board, the surface of moulding has a recess, is transparent material at this recess, and this LED exposes through recess, should
Positive lead and negative lead all extend outside moulding.
Preferably, described pcb board being provided with the first fixing hole, this moulding is provided with the second fixing hole, second is solid
Determine hole with the first fixing hole just to being connected.
Preferably, described moulding is ABS fire proofing material.
Preferably, described LED is three be arranged side by side.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, by above-mentioned technology
By LED being arranged on pcb board, and moulding is coordinated to be fixed together with pcb board produced by insert molding so that this
Product makes volume little, good looking appearance, and parts are few, easy to assembly, and water resistance is good, and cost is lower, solves for user
Cost is high, install a series of difficult problems such as puzzled.
For more clearly illustrating architectural feature of the present utility model and effect, it is right to come with specific embodiment below in conjunction with the accompanying drawings
This utility model is described in detail.

Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of the preferred embodiment of this utility model, include
Pcb board 10 and moulding 20.
Being provided with LED 30 on this pcb board 10, the two ends of pcb board 10 are respectively connected with positive lead 41 and negative pole connects
Line 42, this moulding 20 is fixed together with pcb board 10 produced by insert molding, and moulding 20 wraps pcb board 10, the table of moulding 20
Mask has a recess 21, is transparent material at this recess 21, and this LED 30 exposes through recess 21, this positive lead 41 He
Negative lead 42 all extends outside moulding 20.
In the present embodiment, described pcb board 10 is provided with the first fixing hole 11, this moulding 20 is provided with second solid
Determine hole 22, the second fixing hole 22 with the first fixing hole 11 just to being connected, in order to install fixing with outside.
And, described moulding 20 is ABS fire proofing material, and described LED 30 is three be arranged side by side.
During making, chip mounter LED 30 paster is installed on pcb board 10, and positive lead 41 and negative pole are connected
Wiring 42 is welded on pcb board 10, then, and injection mo(u)lding moulding 20.
Design focal point of the present utility model is: by LED being arranged on pcb board, and coordinates moulding to inlay with pcb board
Embedding molding is fixed together so that this product makes volume little, good looking appearance, and parts are few, easy to assembly, and water resistance
Good, cost is lower, solves a series of difficult problems such as cost is high, installation is puzzled for user.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model,
Within these modes fall within protection domain of the present utility model.
