Plastic shell LED (light-emitting diode) bulb and manufacturing process thereof

Abstract

The invention relates to a plastic shell LED (light-emitting diode) bulb and a manufacturing process thereof. At present, bulb light sources are mainly filament lamps or fluorescent light tubes which have high power dissipation, short service life and non-uniform luminous beams and contain harmful substances such as mercury and the like. The plastic shell LED bulb comprises a shell, an LED light source, an aluminium base PCB (printed circuit board), a radiator and a power source, wherein the shell is divided into three parts of a lamp cap, a plastic shell and a lampshade which are rotatably connected with one another; the plastic shell is made of fire prevention plastic materials; a plurality of lengthwise perforation thermal convection holes A and thermal convection holes B are arranged on the surface of the plastic shell; and the power source, the radiator, the aluminium base PCB and the LED light source are sequentially arranged in the plastic shell from top to bottom. The manufacturing process of the plastic shell LED bulb comprises the following steps of: welding the LED light source on the aluminium base PCB, assembling the radiator, gluing the aluminium base PCB and the radiator by high heat conducting glue, putting the power source at the inner side of the interior of the plastic shell, then locking the LED light source, the aluminium base PCB and radiator components, after connection, assembling lead wires on the lamp cap and putting the lamp cap. The plastic shell LED bulb has simple structure, good heat dissipation effect and long service life, saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of lighting electronics, in particular to an LED light bulb with a plastic shell and a manufacturing process thereof. Background technique [0002] For a long time, people have used incandescent lamps or fluorescent lamps as the main light source for lighting, but these light sources consume a lot of power and have a short lifespan. In particular, fluorescent lamps contain harmful substances such as mercury, which are easy to form mercury pollution and affect people's living environment and health. Healthy, the light lacks softness and uniformity; most of the LED bulbs on the market are metal shells, and there are disadvantages such as high surface temperature and heavy weight of LED bulbs. Contents of the invention [0003] The purpose of the present invention is to provide a LED light bulb with a plastic shell and its manufacturing process, which is used to replace incandescent and fluorescent lamps. It has the ch...
