Description
Technical field
The present invention relates to LED illumination application field.A kind of more particularly it relates to advertising lamp box backlight LED
Module, the module is using the LED module being molded inside a kind of secondary optical lens.
Background technology
This several years also more next extensive with the rapid development of LED technology, the application field of LED.LED module is due to brightness
The features such as high, low in energy consumption, long lifespan, it is widely used in scenes such as advertising lamp boxs.In LED application industries,
LED module is because of its super brightness, the features such as low-power consumption, service life are long, simple installation, is widely used in advertising lamp box, mark
Know the places such as signboard, publicity Warning Mark.With the gradual maturation of LED module technology, its application range also can be more extensive.
LED module on the market is mostly by the way of encapsulating waterproof or injection molded is undertaken to perform work within a time limit and according to specifications skill, wherein encapsulating entirely at present
Waterproof type light decay is big, and production technology replicates；And injection molded is undertaken to perform work within a time limit and according to specifications full skill light source luminescent can be caused it is certain block and
It is unfavorable for secondary optical lens and utilizes (light emitting angle is blocked), so as to cause lamp box number of applications intensive, installation cost is high.
Existing product uses encapsulating, and full bag Shooting Technique mostly.Encapsulating product processes are complicated, easily vulcanize LED shadows
Service life is rung, and wraps that injection Protection Level is low, and can block optical lens shines, and influences light emitting angle entirely, causes normal lamp box to use
Product is intensive, causes the light pollution such as energy waste and dazzle.
The content of the invention
In view of the deficienciess of the prior art, the purpose of this utility model is to provide noted inside a kind of secondary optical lens
The LED module of modeling.
Purpose is stated to realize, the technical solution adopted in the utility model is as follows：Injection inside a kind of secondary optical lens
LED module, including secondary optical lens, pcb board, LED light source, power cord, plastic filler, it is characterised in that：The LED light
Source and power cord are electrically connected with pcb board respectively, and location hole is provided with the pcb board；The plastic filler fits closely
Outside pcb board.The secondary optical lens back is provided with positioning column, which coordinates with the location hole on pcb board.
Preferably, the LED light source is SMD or COB.
Preferably, the secondary optical lens material is PC or PMMA.
Compared with prior art, the utility model at least has the advantages that：By using toward injecting glue in PC glue shells
Shaping, toward injecting glue inside secondary optical lens by the way of the injecting glue of back, is positioned with secondary optics periphery, from back injecting glue,
It is seamless after shaping, dustproof and waterproof ability can be increased substantially.
Brief description of the drawings
Fig. 1 is the explosive view of the utility model.
Fig. 2 is the interior views of secondary optical lens.
Fig. 3 is this practical profile.
1 it is optical lens, 2 is power cord, 3 is pcb board, 4 is plastic filler, 5 is location hole, 6 is LED light source, 7 is
Positioning column.
Embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figs. 1-3, including secondary optical lens 1, pcb board 3, LED light source 6, power cord 2, plastic filler 4, its
It is characterized in that：The LED light source 6 and power cord 2 are electrically connected with pcb board 3 respectively, and location hole 5 is provided with the pcb board 3；
The plastic filler 4 is fitted tightly over outside pcb board 3 and secondary optical lens 1, and the secondary optical lens back is set
There is positioning column 7, which coordinates with the location hole 5 on pcb board.The LED light source 6 is SMD light sources either COB light
Source.
The LED module of injection inside a kind of secondary optical lens provided by the utility model, its production method is two
Secondary optical lens is placed in bottom, power cord and LED light source and other electronic components is connected on pcb board, secondary
Positioning column on optical lens is inserted on the location hole on pcb board, and the component assembled is put into mould at this time, from back
Injecting glue in starting toward secondary optical lens, is positioned using secondary optics periphery, and filled plastics are finally bonded with other member in tight,
It is formed plastic filler 4.Shaped article is seamless, improves the stability of the leakproofness of product, so as to increase substantially
The dustproof and waterproof ability of product and the service life for adding LED module.It is saturating by PC secondary optics that location hole is provided with pcb board
The positioning column set on mirror is assembled on secondary optical lens, as shown in figure 3, LED light source and electronic component are respectively placed in two
Recess on secondary optical lens, pcb board cover this component, so that reached protection LED light source and electronic component,
Reduce the purpose of product fraction defective.This product shell is the secondary optical lens of PC materials either PMMA materials, using back
The mode of injecting glue toward injecting glue inside secondary optical lens avoid light emitting anger from being injection molding glue partial occlusion the problems such as.
The utility model is described in detail above by specific embodiment, these detailed description are only limited to
The content of the utility model is helped skilled in the art to understand, the limit to scope of protection of the utility model can not be interpreted as
System.Various retouchings that those skilled in the art carry out such scheme under the utility model design, equivalent transformation etc. should all wrap
Containing within the protection scope of the present utility model.
