Abstract
The utility model discloses a durable waterproof LED pointolite, including the lamp main part, the lamp main part is including the lamp stand, install the circuit board in the lamp stand, the upper portion of circuit board covers there is the encapsulating layer, the injection molding material that adopted on the encapsulating layer glues for PU. The utility model discloses an adopt the form of encapsulating PU glue to improve the life of LED pointolite. The advantage that PU glue substituted resin glue has: 1 )Resistant yellow stain ability force rate resin is chronic more than 5 times, improves pointolite light transmission greatly, 2 )PU glue solidification back hardness is less than the resin, is lighter than the resin to glue parcel electronic components's internal stress harm, improves lamps and lanterns reliability behind the encapsulating.
Description
Technical field
This utility model relates to a kind of luminaire technology, special LED point light source.
Background technology
Along with industrial expansion, commonly using of point source such as LED product, the occasion such as point source is also used in city building in a large number, night scene is interspersed, decoration, but owing to it is mounted to outdoor high-altitude more, after working long hours, there will be extinguishing, it is difficult to safeguard in time, or maintenance cost is the highest.Rule of thumb sum up, cause caused by the structurally waterproof difference that main reason is that point source that point source extinguishes, and general company uses encapsulated epoxy resin glue pattern on waterproof construction, but the characteristic due to epoxy resin glue, LED point light source after causing by encapsulating is not durable, and after time length, epoxy resin can turn to be yellow and hardening, not only have impact on printing opacity, and aging epoxy resin can reduce the life-span of LED point light source.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of waterproof effect and more robust LED point light source structure.
This utility model solves the solution of its technical problem: a kind of durable waterproof LED point light source, including lamp main body, described lamp main body includes lamp socket, is provided with circuit board in described lamp socket, the top of described circuit board is coated with encapsulating layer, and the injection molding material that described encapsulating layer uses is PU glue.
Further improvement as technique scheme, described lamp socket includes substrate, and described circuit board is arranged on substrate, and described substrate is provided with the boss of annular, described boss is one-body molded with substrate, and described encapsulating layer extends to the peak of boss from the surface of circuit board.
As the further improvement of technique scheme, the inner surface of described boss is provided with multiple tracks and strengthens rib.
As the further improvement of technique scheme, described lamp socket also includes plug, and described plug is provided with the through hole of the through plug of multiple tracks, and described plug is connected by ultrasonic bonding is fixing with substrate.
The beneficial effects of the utility model are: this utility model is by using the form of encapsulating PU glue, to improve the service life of LED point light source.PU glue substitutes the advantage of resin glue to be had: 1) color inhibition energy force rate resin time length more than 5 times, is greatly improved point source light transmission；2) after PU glue curing, hardness is less than resin less than resin, the internal stress infringement for glue parcel electronic devices and components, improves light fixture reliability after encapsulating.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model rather than whole embodiment, and those skilled in the art is not on the premise of paying creative work, it is also possible to obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of this utility model protection.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict.
With reference to Fig. 1, a kind of durable waterproof LED point light source, including lamp main body, described lamp main body includes lamp socket 1, is provided with circuit board 2 in described lamp socket 1, and the top of described circuit board 2 is coated with encapsulating layer 3, and the injection molding material that described encapsulating layer 3 uses is PU glue.
It is further used as preferred embodiment, described lamp socket 1 includes substrate 11, and described circuit board 2 is installed on the substrate 11, and described substrate 11 is provided with the boss 12 of annular, described boss is one-body molded with substrate 11, and described encapsulating layer 3 extends to the peak of boss 12 from the surface of circuit board 2.
Being further used as preferred embodiment, the inner surface of described boss 12 is provided with multiple tracks and strengthens rib.The reinforcement of boss inwall so that PU glue is connected tightr after solidification with boss, thus strengthens bulk strength and better tightness.
Being further used as preferred embodiment, described lamp socket 1 also includes plug 13, and described plug 13 is provided with the through hole of the through plug of multiple tracks 13, and described plug 13 is connected by ultrasonic bonding is fixing with substrate 11.Utilize together with plug welds with substrate by ultrasonic welding technique, improve the sealing of LED point light source, effectively prevent moisture from entering into inside LED point light source via plug.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the application claim limited range.
