Title:
AC-DRIVEN BULB TYPE LED LAMP
Document Type and Number:
WIPO Patent Application WO/2019/054763
Kind Code:
A1
Abstract:
The present invention relates to an AC-driven bulb type LED lamp comprising: a bulb unit having a bulb-shaped body made of glass, and having heat dissipating gas injected and filled therein in order to lead, to the outside, heat generated from an LED light emitting unit, which is a light emitting body; a heat dissipating unit positioned beneath and coupled to the bulb unit, and dissipating, to the outside, heat generated from an AC driver mounted therein; a socket base unit positioned beneath and coupled to the heat dissipating, and electrically connected to the AC driver; an LED light emitting unit, which is a light emitting body arranged in the bulb unit, is composed of LED bars having AC driving chip LEDs arranged on a bar-shaped board, has upper and lower end parts, which are fixed and coupled, in a vertically arranged state, to a pair of stamp rings vertically spaced and fixed in the bulb unit, has a plurality LED bars radially arranged, and is electrically connected to the AC driver; the AC driver fixed in the heat dissipating unit, and electrically connected to the LED light emitting unit, which is composed of the plurality of radially arranged LED bars, so as to control supply of alternating current power and light emission; a support positioned and vertically arranged in the bulb unit, having a lower end part fixed on the heat dissipating unit for the driver, and serving a role for fixing and supporting the pair of stamp rings to be placed on a predetermined space in the bulb unit; and an insulator arranged at both side parts on which the pair of stamp rings are provided and coupled onto the support in order to perform an insulation function for preventing shorting at the sides of the pair of stamp rings when AC power is supplied.
