Abstract
The invention relates to a light-emitting diode (LED) bulb lamp, in particular to an LED bulb lamp with a flame-retardant plastic shell. A lamp holder is matched with the upper cover of the plastic shell in a screwing way. The upper cover of the plastic shell is matched with a light diffusion bottom cover in a clamping way. A driving power supply, a radiator, an aluminum substrate and an LED light source which is stuck on the aluminum substrate are arranged between the upper cover of the plastic shell and the light diffusion bottom cover in a matching way. At least four fixed columns are arranged in the upper cover of the plastic shell. The driving power supply and the radiator are respectively matched with the fixed columns in the upper cover of the plastic shell in a screwing way through bolts. The radiator and the aluminum substrate are arranged to be an integral structure. A group of LEDs is welded on the aluminum substrate. The group of LEDs forms the LED light source. The LED bulb lamp with the flame-retardant plastic shell directly works under 200V alternating-current input voltage, the upper cover of the plastic shell is the flame-retardant plastic shell and is not electrically conductive, and air heat insulation is realized between the upper cover of the plastic shell and the internal LED radiator. Compared with a high-power combined bulb lamp with a shell and a radiator which are integrally arranged, the advantage in safety performance is very great, and even though internal current leakage or heating occurs, people are very safe to touch the LED bulb lamp.
