The utility model content
The utility model provides a kind of led module, in order to solve exist in the prior art when processing presses copper stud, usually can touch electronic devices and components such as Chip-R on the PCB lamp plate, capacitor, IC, cause problem with its damage.
For reaching above-mentioned purpose, the utility model provides a kind of led module, and described led module comprises the led module housing, and is installed in PCB lamp plate and LED face shield on the described led module housing successively; Wherein, described led module housing is provided with PCB fixing glue post and LED face shield fixing glue post, and described PCB fixing glue post, LED face shield fixing glue post are fixed on described PCB lamp plate and LED face shield on the described led module housing by fixture respectively.
Further, described PCB fixing glue post, LED face shield fixing glue post and described led module housing are injection molded into integrative-structure.
Further, also be provided with the led module fixing hole on the described led module housing.
Further, described fixture is a tapping screw.
The utility model beneficial effect is as follows:
LED face shield fixing glue post is set on housing, be connected with LED face shield fixing glue post by self-tapping screw, the LED face shield is fixed on the PCB lamp plate, avoid damaging electronic devices and components such as Chip-R on the PCB lamp plate, capacitor, IC, reduced the spoilage in the led module production process, and then reduced production cost of products, and increased the reliability of led module simultaneously, improved product quality.In addition, LED face shield fixing glue post and led module housing are injected into integrative-structure, have reduced the step that the copper stud that presses is installed on the PCB lamp plate, improved production efficiency.And, replace pressing copper stud by LED face shield fixing glue post, reduced the cost of led module, increased competitiveness of product.
