Graphene plastic casing light-emitting diode (LED) bulb lamp and production method thereof

Abstract

The invention provides a graphene plastic casing light-emitting diode (LED) bulb lamp and a production method thereof and belongs to the field of LED illumination. At present, an LED bulb lamp is provided with a metal casing and has the problem of a potential safety hazard that the temperature on the surface of an LED lamp body is high so as to cause electric shock easily. The graphene plastic casing LED bulb lamp comprises a lamp holder, a driving power supply, a light source base, an LED light source, a casing and a light transmitting bulb casing and is characterized in that the casing is a fireproof plastic casing with the inner surface coated by a graphene material. The production method of the graphene plastic casing LED bulb lamp includes: step one, preparing parts of each component; step two, coating the graphene material on the inner surface of the casing; step three, solidifying the graphene material on the casing in the step two; step four, assembling the parts of each component in sequence; and step five, detecting and debugging. The graphene plastic casing LED bulb lamp and the production method of the graphene plastic casing LED bulb lamp have the advantage that high thermal conductivity performance of graphene is applied to the plastic casing of the LED bulb lamp and the light source base, the defect that an existing high-power bulb lamp solves the problem of heat dissipation through increasing of volume and weigh of a metal casing or a metal radiating support is overcome, and the LED bulb lamp is simple in structure, good in radiating effect, long in service life and convenient in popularization and application.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a graphene plastic case LED bulb lamp and a production method thereof. Background technique [0002] Due to its high luminous efficiency, long life, energy saving and environmental protection, LED bulb light source has been widely used as a new light source to replace traditional incandescent or fluorescent tubes. With the increase of the power of LED bulb lamps, the heat dissipation of LED lamps is always an important factor affecting the overall lighting effect and life of LEDs. Most of the LED bulb lamps currently on the market are made of metal shells, and the surface temperature of the LED lamp body is high, which is likely to cause potential safety hazards such as electric shock. There are also some bulb lamps that use a metal skeleton to dissipate heat and then install a plastic shell on the outside, such as the LED bulb lamp that uses the chimney effect to dissipate heat in t...
