Description

TECHNICAL FIELD

[0001] The utility model relates to lighting lamps and lanterns technical field, concretely for a kind of quick-mounting type insulating aluminum substrate fixing structure for lamps and lanterns. BACKGROUND

[0002] In existing LED lighting products, aluminum substrate is used as the circuit board for bearing LED lamp beads, and is usually directly locked and fixed on the bottom disc or support of the lamp by screws. This fixing method has significant defects. First, positioning is needed before screwing during installation, and the installation process is cumbersome. Second, if the screw deviates or slips during locking, its head may accidentally contact the conductive circuit on the aluminum substrate, causing the aluminum substrate and the metal bottom disc to be directly conductive, resulting in the risk of electric leakage. Third, when the lamp circuit is connected incorrectly, the LED lamp beads will produce a "residual light" phenomenon because the aluminum substrate is electrically connected to the bottom disc through the screw.
