LED LAMP BULB AND LED LIGHTING BAR CAPABLE OF EMITTING LIGHT OVER 4?

摘要

An LED lamp bulb and an LED lighting bar capable of emitting light over 4p are provided. The LED lamp bulb includes a shell (1) for the LED lamp bulb, a core pole (5) with an exhaust tube (2) and a bracket (42), an LED strip (6) with at least one 4p lighting LED chip, a driver (7) and an electrical connector (8). The LED lamp bulb shell and the core pole are sealed in vacuum so as to form a vacuum seal chamber (13). The vacuum seal chamber is filled with a gas having a low viscosity coefficient and high heat conductivity. The bracket and the LED lighting bar fixed on the bracket are accommodated in the vacuum seal chamber. The LED lighting bar, the driver and the electrical connector are electrically connected in order. The electrical connector and the external power source are electrically connected.
