Safety-increasing glue irrigating driving box and a lamp using the same

Abstract

A safety-increasing glue irrigating driving box comprises an upper cover, an enclosing shell and a bottom shell, wherein the enclosing shell comprises a first opening end and a second opening end, the first opening end and the second opening end are oppositely arranged, the bottom shell is of a frame structure with one end closed and the other end open, the bottom shell comprises a base plate, the first opening end of the enclosing shell is in seal fit with the upper cover, the second opening end of the enclosing shell is fixedly connected with the base plate of the bottom shell, a plurality of partition plates vertically inserted in the base plate of the bottom shell are arranged in the enclosing shell, a driving plate glue irrigating groove used for containing a driving plate is formed between each two partition plates, and a plurality of connection wire glue irrigating grooves used for glue irrigating of connection wires of the driving plates are arranged at two ends of the base plate of the bottom shell along the first direction of the base plate. According to the safety-increasing glue irrigating driving box, glue irrigating thickness of the driving plate glue irrigating grooves only needs to be at least 3 mm larger than height of the diving plates to meet anti-explosion requirements, the glue irrigating thickness of the connection wire glue irrigating grooves can be smaller than the glue irrigating thickness of the driving plate glue irrigating grooves, the anti-explosion requirements are met, and glue irrigating cost is saved. The invention further provides a lamp using the safety-increasing glue irrigating driving box.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a safety-increasing glue-filling drive box and a lamp using the safety-enhancing glue-filling drive box. Background technique [0002] The drive box installed inside various increased safety explosion-proof lighting fixtures is responsible for the dual functions of protecting the drive circuit board and accommodating glue filling. GB / T 3836.3 stipulates that the safety-increasing circuit needs to be filled with epoxy colloid that exceeds the height of the circuit board by more than 3mm, and can dissipate heat reliably. [0003] At present, the safety-increased explosion-proof drive boxes on the market are all simple box-shaped structures made of sheet metal or polycarbonate. Generally, the peripheral length, width, and height dimensions are individually customized according to the size of the drive circuit board, and then filled with epoxy glue. Finally add the lid. The safety-increased ex...
