The utility model provides a kind of New LED illuminating module, including bottom case, be fixed on bottom shell pcb board and position
In at least one LED light source on the pcb board, the light-emitting surface of the pcb board and LED light source is covered with marine glue, described
Marine glue on the light-emitting surface of LED light source forms lens shape.
LED illuminating modules provided by the utility model are covered with marine glue using the light-emitting surface of pcb board and LED light source, and
Marine glue on the light-emitting surface of LED light source forms spherical lens shapes, is reaching outdoor water-proof purpose simultaneously, is increasing light source die
The expansion photosensitiveness of group simultaneously reduces production cost.
Further, the lens shape is dome shape.
Further, the light-emitting surface of the LED light source is concave face.
Further, the LED light source bottom has solder joint, the solder joint to be covered in below marine glue with pcb board joint.
Further, the bottom case inner bottom surface and the leaded hole in pcb board quadrangle, conducting wire are drawn by fairlead.
Further, there is mounting hole at bottom case outer bottom both ends.
Further, level of the height of marine glue provided around the LED light source not higher than the light-emitting surface of LED light source
Highly.
A kind of luminous display unit with the LED illuminating modules that the utility model is proposed, including it is any of the above-described
The LED illuminating modules that item is previously mentioned.
Luminous display unit provided by the utility model with the LED illuminating modules is shone by the application LED
Module has many advantages, such as that good water-proof effect, light-emitting surface are uniform and shaded area is small, at low cost and production efficiency is high.

Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings.Below by
The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and should not be understood as new to this practicality
The limitation of type.
If Fig. 1,2, LED illuminating modules include bottom case 4, the pcb board 3 being fixed on inside bottom case 4 is located on the pcb board 3
At least one LED light source 2, it is characterised in that：The light-emitting surface of the pcb board 3 and LED light source 2 is covered with marine glue 1, described
Marine glue 1 on the light-emitting surface of LED light source 2 forms lens shape 6.The lens shape 6 is dome shape.The LED light source 2
Light-emitting surface is concave face.2 bottom of the LED light source has solder joint 21, the solder joint 21 to be covered in marine glue 1 with 3 joint of pcb board
Lower section.4 inner bottom surface of the bottom case and 3 four jiaos of leaded holes 7 of pcb board, conducting wire 5 are drawn by fairlead 7.4 outer bottom of the bottom case
There is mounting hole 8 at both ends.Level of the height of marine glue 1 provided around the LED light source 2 not higher than the light-emitting surface of LED light source 2
Highly.LED illuminating modules are fixed on special fixture, using glue pouring machine automatic glue filling, form waterproof mould composition after glue is dry
Product.
As Fig. 3 provides for the utility model embodiment the enlarged drawing of the local I of the LED illuminating modules of Fig. 1, the utility model
Unlike existing filling epoxide-resin glue module, marine glue 1 directly overlies the surface of LED light source 2.The table of LED light source 2
Face has the recess of certain radian, presents bowl-shape.In module after adhesive injection device gluing, due to the surface tension of liquid, stream
Dynamic glue can form dome shape glue on 2 surface of LED light source, and lens shape 6 is formed after glue is dry.Entire pcb board 3 includes LED light source
2, the positions such as solder joint pad of the solder joint 21 of LED light source, conducting wire obtain glue covering, expand while possessing former water-proof function
The light emitting angle of light source module group.
The marine glue used in the utility model is bi-component organic silicon glue, cooperated with LED light source.According to the utility model reality
It applies epoxy resin packaged by LED light source in example and forms finished product rear surface with slight recess so that light source surface can accommodate
