Led lighting apparatus having flame barriers

A LED lighting apparatus, comprising:

• a LED module including a substrate having a front surface and a rear surface, and a plurality of LEDs mounted on the front surface of the substrate and driven by direct input of AC voltage;
• a plurality of capacitors disposed at the rear side of the substrate of the LED module in a lying position and connected to the LEDs to eliminate flickering of the LEDs;
• a heat sink attached on a surface of a ceiling panel, the heat sink including a base plate and a heat dissipating annular rim, wherein the heat dissipating annular rim is extended outwardly and circumferentially from the base plate, and wherein the base plate is attached to the LED module so as to dissipate heat from the LEDs;
• a flame barrier plate made of UL 94-5VA rated flame-retardant polycarbonate resin and covering the front surface of the substrate of the LED module so as to insulate the LED module from fire flame;
• a plurality of capacitor housings made of UL 94-5VA rated flame-retardant polycarbonate resin, wherein each of the capacitor housings has an opening formed at a front side and accommodates each capacitor so as to insulate the capacitor therein from fire flame;
• a flame barrier film made of flame-retardant material and covering the opening of the capacitor housing;
• and
• a lens detachably coupled to the rim of the heat sink,
• wherein the base plate includes a plurality of through holes which allow a rear portion of each capacitor housing to pass though so as not to obstruct contact between the base plate and the rear surface of the substrate.

A LED lighting apparatus, comprising:

• a LED module including a substrate having a front surface and a rear surface, and a plurality of LEDs mounted on the front surface of the substrate and driven by direct input of AC voltage;
• a plurality of capacitors disposed at the rear side of the substrate in an upright position, and the capacitors being connected to the LEDs so as to eliminate flickering of the LEDs;
• a heat sink including a base plate detachable coupled to the LED module to absorb heat from the LEDs on the substrate and a plurality of fins upright extended from the base plate to dissipate heat from the base plate;
• a flame barrier plate covering the front surface of the substrate of the LED module to insulate the LED module from fire flame and being made of UL 94-5VA rated flame-retardant polycarbonate resin, and having a central hole to allow the light beam of the LEDs to pass therethrough;
• a plurality of capacitor housings made of UL 94-5VA rated flame-retardant polycarbonate resin to enclose the capacitors, wherein each of the capacitor housings comprises a first wall extended upwardly from one side of the flame barrier plate and a second wall detachably coupled to the first wall;
• a reflector detachably coupled to a bottom surface of the heat sink to guide the light beam of the LEDs;
• and
• a can surrounding the reflector and being installed into a mounting hole of a ceiling panel.
