Title:
LED LAMP PANEL, HIGH-VOLTAGE PULSE PROTECTION CIRCUIT OF LED LAMP PANEL AND LED LAMP
Document Type and Number:
WIPO Patent Application WO/2015/149210
Kind Code:
A1
Abstract:
An LED lamp panel, a high-voltage pulse protection circuit of the LED lamp panel and an LED lamp are disclosed. The LED lamp comprises a lamp holder, an insulating base, an LED driving power supply (10), a metal heat-dissipation shell (20), an LED lamp panel (30) and a lampshade. The LED lamp panel (30) is locked and fixed on the metal heat-dissipation shell (20) through a screw (40). The LED lamp panel (30) comprises an LED circuit board (31) and LED light sources (32). The LED circuit board (31) is provided with an electric positive electrode interface and an electric negative electrode interface, and the LED light sources (32) are connected between the electric positive electrode interface and the electric negative electrode interface. A high-voltage bypass capacitor (C1) is additionally arranged on the LED circuit board (31). One terminal of the high-voltage bypass capacitor (C1) is connected to the electric negative electrode interface, and the other terminal is connected to the screw (40) so as to be connected with the metal heat-dissipation shell (20) to realize the ground connection, and therefore a bypass discharging path is formed to discharge the high voltage to an output terminal. Thus, the LED light sources are prevented from being broken down by high-voltage pulses, and are protected from damages caused by high-voltage lightning strokes.
