Abstract

The invention relates to a light emitting diode (LED) bulb lamp, comprising a lamp shell, a lamp cap, at least two conductive supports, and a luminous part, wherein the lamp cap is connected with thelamp shell so as to form a containing space; the lamp cap comprises a drive circuit; the luminous part comprises a light conversion coating, a plurality of LED chip units coated with the light conversion coating, a conductor section, and at least two electrodes which are respectively connected with the conductive supports; any of the LED chip units comprises at least two LED chips which are connected by means of wires; the LED chip units are electrically connected by means of conductor sections in the luminous part; part of each electrode is exposed outside the light conversion coating; the electrodes are connected with the LED chip units by means of first wires, and the conductor sections are connected with the LED chip units by means of second wires; copper foil and LED chips are stuck on an LED lamp filament substrate; the LED chips as well as the first wires and the second wires which are connected with the LED chips are separately wrapped by a first light conversion layer, so thatthe heat radiation area is enlarged, the heat dissipation effect is improved, and the luminous efficiency is increased.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an LED filament and an applied LED bulb lamp. Background technique [0002] Incandescent light bulbs have been widely used for home or commercial lighting for decades, however, incandescent light bulbs are generally less efficient in their energy use, with approximately 90% of the energy input being dissipated as heat. And because incandescent bulbs have a very limited lifespan (about 1,000 hours), they need to be replaced frequently. These traditional light bulbs are gradually being replaced by other more efficient electric lamps, such as fluorescent lamps, high-intensity gas discharge lamps, light-emitting diodes (LEDs), etc. Among these electric lamps, LED lamps are the most striking lighting technology. LED lights have the advantages of long service life, small size, and environmental protection, so their applications continue to grow. [0003] In recent years, there have been LED ...
