Description

A kind of anti-scattered light type LED module

Technical field

The utility model is related to technical field of LED illumination more particularly to a kind of anti-scattered light type LED modules.

Background technology

On Vehicles Collected from Market, due to economic and environment-friendly, many advantages spy such as low, long working life, small, light-weight of consuming energy Point, LED module are widely used in advertising lamp box, the inside of advertisements character learning as lighting source purposes.In order to coordinate difference The demand of optical effect, the LED module used at present are to shine to carry out secondary light-distribution to LED by the way of lens are increased, But lens currently on the market are made of using transparent material, and in column shape, then go out photoreduction process in LED module In, astigmatism will necessarily be sent from the cylinder of lens, and this dispersing light can seriously affect the actual optical effect of product, so as to lead Cause actual application effect poor；Still further aspect, injection molding LED module currently on the market, internal component are not done It is effectively isolated, direct integral molded plastic, due to the stress of injection moulding plastic material, the stress of component can be caused even to damage, from And product is caused to occur damage phenomenon in the early stage or in use for some time, so as to which the LED illumination product long-life be not achieved Anticipated demand.

Utility model content

In order to solve above-mentioned prior art problem, the utility model provides a kind of anti-scattered light type LED module.

Realize the utility model aim a kind of anti-scattered light type LED module, including plastic shell, component protective cover, thoroughly Mirror and PCBA, which is characterized in that the PCBA includes one or more LED, power supply module and pcb board, and the LED is fixed on institute It states on pcb board, the lens are fixed on the corresponding pcb board positions of the LED, and the power supply module is fixed on described On pcb board, the component protective cover is fixed on the corresponding pcb board position of the power supply module, and the component is protected Power supply module described in guard covers, the plastic shell are provided with one or more anti-astigmatism thin-walleds.

Further, PCBA, the lens and the component protective cover are stated in the plastic shell sealed envelope residence, and The component protective cover is reserved at the part exposure of the light-emitting surface corresponding to the LED of the lens and reserves to correspond to At the top of the power supply module locally exposure.

Further, anti-astigmatism thin-walled structure in a ring, can be circular ring shape or the side's of being annular.

Further, the inner surface of the anti-astigmatism thin-walled states the outer cylinder of lens around residence, and the anti-astigmatism is thin The upper end of wall is concordant with the top of the lens.

Further, the height construction of the plastic shell outer surface is the height more than or equal to the component protective cover Degree.

The utility model has the advantages that：By increasing anti-astigmatism thin-wall construction in existing injection molding LED module, wrap up The firmly cylinder position of lens so that LED effectively stopped or reflected back from the light extraction of lens post face position, allow LED all from Lensed tip end face light extraction effectively controls astigmatism, improving optical effect.In addition, by increasing individual component protective cover knot Structure so that each component is effectively isolated with plastic shell in power supply module, and the material avoided the occurrence of in injection moulding process should The influence of power and mechanical interference is effectively protected the reliability of component, certain so as to be obtained to the service life of product It ensures.

Specific embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples.

With reference to shown in figure 1, Fig. 2, the utility model provides a kind of anti-scattered light type LED module in fact, includes plastic shell （1）, component protective cover（2）, lens（3）And PCBA（4）.

Wherein, the PCBA（4）By one or more LED（41）, power supply module（42）It is formed with pcb board.Power supply module （42）Include several electronic components, in arrangement is concentrated, power supply module is primarily served to LED several electronic components （41）Constant current-supplying acts on.When making this LED module, by SMT welding manners, by LED（41）It is welded to pcb board fixed position On, by power supply module（42）In electronic component be welded on the fixed position of pcb board.

Further, by the component protective cover（2）It is fixed on the power supply module（42）Corresponding pcb board it is corresponding On position.In the present embodiment, component protective cover（2）Fixed form be by being arranged on component protective cover（2）Lower section Two card bases are fixed on pcb board.Other fixed forms include but not limited to that screw is fixed, glue is adhesively fixed.

Further, by the lens（3）It is fixed on the LED（41）On the corresponding position of corresponding pcb board.This implementation In example, lens（3）Fixed form be by being arranged on lens（3）Two card bases of lower section are fixed on pcb board.Other fixations Mode includes but not limited to that screw is fixed, glue is adhesively fixed.

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）Reserve the lens（3）Corresponding to the LED（41）Light-emitting surface it is sudden and violent At dew, ensure LED the advantage of doing so is that taking into account（41）Light-out effect and lens（3）Mechanically stable reliability.But this Field technology personnel are appreciated that the design needs according to actual product, the plastic shell（1）Reserve the lens（3）It is right LED described in Ying Yu（41）Exposure at position can suitably be adjusted, these fall within the scope of protection of the utility model.

Further, the plastic shell（1）It is wrapped in the lens（3）The structure division of outer cylinder set to be special Anti- astigmatism thin-walled（11）, the anti-astigmatism thin-walled（11）Top position and the lens（3）Top light-emitting surface it is concordant, this The benefit that sample is done is to ensure LED（41）In lens（3）Whole light extractions of cylinder site location are effectively stopped or are reflected back.But It is, it will be understood by those skilled in the art that according to the design needs of actual product, the anti-astigmatism thin-walled（11）Top position Height can be less than the lens（3）Top light-emitting surface height, these fall within the scope of protection of the utility model.

In the present embodiment, the plastic shell（1）Outer surface reserve the component protective cover corresponding to the power supply At the top of component group locally exposes, the plastic shell（1）Outer surface height construction be more than or equal to the member Device protective cover（2）Height.But it will be understood by those skilled in the art that according to the design needs of actual product, the modeling Glue shell（1）The height construction of outer surface can also be less than the component protective cover（2）Height, these fall within this reality With new protection domain.

Embodiment described above only expresses the embodiment of the utility model, description more specifically in detail, but simultaneously Cannot the limitation to the utility model patent scope therefore be interpreted as.It should be pointed out that the ordinary skill for this field For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this The protection domain of utility model.
