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
The present invention relates to the electronic applications that throws light on, be specifically related to a kind of plastic shell LED bulb and manufacture craft thereof.
Background technology
For a long time, the illuminating bulb source of people is mainly incandescent lamp or fluorescent tube, but these light source power consumptions are big, the life-span short, particularly fluorescent tube contains harmful substances such as mercury, form easily mercury pollution, influenced people's living environment and healthy, light lacks soften, the uniformity; Existing LED bulb on the market mostly is metal shell, has LED tube face temperature height, deficiencies such as preponderance.
Summary of the invention
The object of the present invention is to provide a kind of plastic shell LED bulb and manufacture craft thereof, be used for replace incandescent and fluorescent lamp, have characteristics such as energy-conservation, safe, light environmental protection and long-life, have great economic benefit and social benefit.
The present invention is made of housing, led light source, aluminum base PCB plate, radiator and power supply.Housing is divided into lamp holder, plastic shell and lampshade three parts, the spin bottom of plastic shell of lamp holder, and lampshade is screwed in the top of plastic shell; Plastic shell is the fire prevention plastic cement material, the plastic shell surface is provided with the thermal convection current hole A and the thermal convection current hole B of a plurality of vertical perforations, plastic shell inside sets gradually power supply, radiator, aluminum base PCB plate and led light source from top to bottom, led light source is welded on the aluminum base PCB plate, and aluminum base PCB backboard face is provided with radiator.
Manufacture craft of the present invention is: earlier led light source is welded on the aluminum base PCB plate, and then assemble radiator, bonding between aluminum base PCB plate and the radiator by high-heat-conductivity glue, it is inner inboard that power supply is put into plastic casing, lock led light source, aluminum base PCB plate and heat sink assembly then, load onto lamp holder after having connected lead, put on a lampshade at last.
During use, through producing the strong convection benefit between accurate thermal convection current hole A that designs of calorifics and the thermal convection current hole B, rapidly the heat on the radiator is taken away, led light source is remained under the lower temperature environment works, guarantee that led light source increases the service life, it is luminous even that plastic shell adds that optical grade high transmission rate lampshade makes, and free from glare is comfortable soft.
The invention has the advantages that simple in structure, reliable, good heat dissipation effect, life-span are long, easy to use, quick, production efficiency height, light efficiency are evenly soft, and electromagnetic-radiation-free, mercury pollution, energy-conserving and environment-protective are used in extensive rangely, are beneficial to popularization.
