Abstract

An LED lighting unit (1) includes a housing (10), a circuit board (31) and a seal member (50). The seal member includes a seal main body (51) inserted into the housing in an insertion direction, a wire insertion portion (60), a protrusion piece (61) protruded from a rear surface of the seal main body opposite to the insertion direction. A holder (70) is arranged at one side of an opening of the housing relative to the seal member and includes a guide base (71) inserted into the housing, a protruded wire guide portion (74) protruded from a front end surface of the guide base and arranged at a position facing the wire insertion portion within the housing, and a wire lead portion (72a) leading an electric wire from a position adjacent to the guide base to the external. The opened surface of the housing coincides with a rear end surface of the guide base within the housing.

Description

technical field [0001] The invention relates to an LED lighting unit in which a circuit board on which LED (Light Emitting Diode) elements are installed is accommodated in a casing. Background technique [0002] A circuit board having LED (Light Emitting Diode) elements mounted thereon is housed in the LED lighting unit in the case, and while maintaining waterproofness, wires having one end connected to the circuit board are led out from the opening of the case. Thus, a sealing material that maintains waterproofness within the housing is required to lead out the contents of the housing. Therefore, a large number of parts are added, and the assembly work becomes complicated. In this case, for example, Patent Document 1 proposes a crimp terminal fixing structure of a crimp connector and a seal that securely fix the crimp terminal and the seal in a block.
