Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

With reference to shown in Fig. 1, Fig. 2, it includes outside plastic cement that the utility model provides a kind of new construction LED injection mould group in fact Shell (1), PCBA(2), lens (3), for electric pole (4) and convered structure (5).

Wherein, the PCBA(2) by one or more LED(21) and pcb board (22) form.When making this LED module, lead to SMT welding manner is crossed, LED(21) is welded on pcb board (22) fixed position.The lens (3) are fixed on the LED (21) on the corresponding position of corresponding pcb board (22).In the present embodiment, the fixed form of lens (3) is by being arranged in lens (3) two card bases below are fixed on pcb board (22).Other fixed forms include but is not limited to that screw is fixed, glue is bonded It is fixed etc..

Further, one fixation hole (221), this fixation hole (221) are set in the middle position of the pcb board (22) Circular in shape.According to the design needs of actual product, the quantity of the fixation hole (221) can be multiple.

Further, described one end for electric pole (4) is welded by the end that welding manner is fixed on the pcb board (22) Pan Weizhichu, the other end for electric pole (4) are in unlocked state.By being designed in pcb board (22) into copper circuit is covered, By pcb board (22) end pad and each LED(21) between formed and be effectively electrically connected.The quantity for electric pole (4) is Two groups totally 4, the both ends of pcb board (22) are respectively arranged one group 2 for electric pole (4).It is used when LED injection mould group needs to cascade When, it being sequentially connected for electric pole (4) by different mould groups.

Further, after completing above-mentioned operation, by using the mode of injection molding machine injection molding, the plastic shell is completed (1) tight.

In the present embodiment, the plastic shell (1) reserves the lens (3) corresponding to the sudden and violent of the LED(41) light-emitting surface At dew, the advantage of doing so is that take into account guarantee LED(21) light-out effect and lens (3) mechanically stable reliability.The modeling The height construction of the outer surface of glue shell (1) is less than the height of the lens (3).

Further, it is additionally provided with annular convex platform (11) at the top of the plastic shell (1), the inner ring side of annular convex platform (11) Circular in shape, the hexagonal shape of outer rim side of annular convex platform (11), the annular convex platform (11) by inner ring side with it is described The lateral wall of lens (3) is fitted closely.The quantity of the annular convex platform (11) is identical as the quantity of the lens (3).

In the present embodiment, the plastic shell (1) is reserved at the bottom-exposed of the pcb board (22), and institute's convered structure (5) is solid It is scheduled on the bottom position of the pcb board (22), the area of the convered structure (5) is less than or equal to the bottom of the pcb board (22) Area.Convered structure (5) can effectively solve the problems, such as product in a pre-installation the phase pre-fix.

In the present embodiment, the plastic shell (1) is reserved at the exposure of fixation hole (221) position in the pcb board (22). When product needs to install for a long time in use, can pass through this fixation hole (221) using the screw of appropriate specification and be locked at peace It fills on surface.

In the present embodiment, the plastic shell (1) is reserved at the extension outlet exposure for electric pole (4), it can will It is led to outside product for electric pole (4) from pcb board (22) weld, passes through the real for the connection between electric pole (4) of different product The long cascade characteristic of existing product.
