Description

[Technical field]

[0001] The utility model relates to the technical field of lighting brackets, in particular to a waterproof LED plane bracket with a base. [Background technology]

[0002] In traditional flat LED brackets, the length of one side of the base usually accounts for more than 80% of the single side of the entire product. This structural design results in a large contact area between the metal sheet, PPA material and the encapsulation glue on the bracket base, and a relatively large amount of encapsulation glue is used; the expansion coefficients of the metal sheet and the encapsulation glue are quite different, and the product moisture sensitivity level is poor; after the structure is exposed to the air for a certain period of time, it is more likely to cause abnormal delamination of the colloid and the bracket. The path for external water vapor to penetrate into the metal sheet and chip in the base is shorter, and the water vapor produces electrolysis when powered on, causing metal migration, which reduces the service life of the lamp beads. [Contents of the utility model]

[0010] The base as described above is a waterproof LED flat bracket, and the wall thickness section of the base body is tapered.

[0011] In the waterproof LED flat bracket formed by the base as described above, the lateral length of the circuit arrangement area is 65% of the lateral length of the bottom edge of the base body.

[0013] The base is a waterproof LED flat bracket as described above, and the circuit arrangement area is provided with electronic components for connecting the circuit.
