Abutted against with the openend 312 of accommodating body 310.In other embodiments, it can further set one or more recessed on main part 324
Annular groove, plastic tube is arranged with concave ring groove, to realize tight fit with accommodating body 310.
Wherein, the inwall of the openend 312 of power storehouse 320 and accommodating body 310 is by laser welded seal, as shown in figure 13
E at；The junction of power storehouse 320 and sheet illuminator 330 is sealed by encapsulating (not shown), at F as shown in figure 11.It is excellent
Selection of land, encapsulating are located at the inside of power storehouse 320, and encapsulating partially or fully fills up jack 322 and power storehouse 320.Due to filling
Glue partially or fully fills up jack 322 and power storehouse 320, and its technique is simple, cost is also very good compared with bottom, sealing effectiveness.
In the present embodiment, the concrete structure of sheet illuminator 330 can be retouched above with reference to accompanying drawing 5,6,15-17 and reference
State, here is omitted.
In the present embodiment, accommodating body 210 is provided with the 3rd buckle structure 312, and lamp holder 250 is provided with and the 3rd buckle structure
The 4th buckle structure coordinated, lamp holder 250 are connected together with accommodating body 210.
In above example, without designing independent pressure reduction structure, the heat absorption expansion for cooling medium, the application uses
Thermal source is reduced, and is absorbed by the elastic printing opacity sealing for diaphragm seal shape illuminator, further can be by soft material system
Into power storehouse absorb, can also by closed accommodating cavity reserve air absorb.
In summary, those skilled in the art, which hold, understands, light fixture provided by the invention uses sheet illuminator, the letter of its structure
List, radiating is good, is easy to seal, and greatly reduces production difficulty and cost.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
