LED bulb is a kind of lighting fixture with high efficiency, high color rendering index and long life. It usually consists of LED lamp beads, radiator, driving power supply and lampshade. The appearance design of LED bulbs is similar to traditional incandescent bulbs, but its energy efficiency and environmental performance are better than incandescent bulbs.
LED bulbs have the following advantages:
1. High energy efficiency: LED bulbs are much more energy efficient than incandescent lamps. They can convert more electrical energy into light energy, thereby reducing energy waste.
2. Long life: The service life of LED bulbs is much longer than that of incandescent lamps, usually up to tens of thousands of hours, thus reducing the time and cost of replacing bulbs.
3. Environmental protection: LED bulbs do not generate a lot of heat and ultraviolet rays like incandescent lamps, so they will not have a negative impact on the environment.
4. High color reproduction: LED bulbs have a high color rendering index, which can better restore the true color of objects, thus improving the visual effect.
5. Easy to install: LED bulbs are installed in the same way as incandescent bulbs and can easily replace traditional bulbs.
In short, LED bulb is an efficient, environmentally friendly and long-life lighting product, suitable for lighting in homes, offices, shopping malls and other places. As people pay more and more attention to environmental protection and energy saving, the application prospects of LED bulbs will become increasingly broad.
The production process of LED bulbs mainly includes the following steps:
Shell production: Making the shell of the LED bulb, usually made of plastic or glass material, and the shape of the shell is spherical. There is a thermal base inside the housing for fixing the LED lamp beads.
Power supply production: To make the power supply for LED bulbs, constant current source technology is generally used to ensure the normal operation of the LED lamp beads. The power supply part needs to be combined with the casing to facilitate subsequent assembly.
Lamp bead production: Select high-quality LED lamp beads, and test the positive and negative poles of the lamp beads to ensure that the quality of the lamp beads is qualified.
Light source board: Attach the LED lamp beads to the aluminum substrate using an SMD placement machine or manual placement. Then put the lamp board into the reflow soldering machine for soldering. Pay attention to temperature control during the soldering process to avoid damage to the lamp beads.
Test: After the welding is completed, conduct a power-on test on the finished product to check the lighting status of the LED to ensure that the brightness and color are consistent, and there are no abnormal phenomena such as flickering and false soldering.
Assembly: Use a bulb assembly machine to assemble the light source plate, bulb, lamp cup, and lamp holder into finished products; the assembly machine includes a bulb assembly machine, a glue machine, a light source plate stamping machine, a lamp holder locking machine, and a laser marking machine. Aging line etc.
Packaging: Pack the qualified LED bulbs, indicating product specifications, power, voltage and other parameters.
Finished product: Finally, the packaged LED bulbs will undergo factory inspection and can be put on the market after passing the test.
During the entire production process, attention needs to be paid to preventing static interference and ensuring product quality. In addition, in order to ensure the service life and performance of LED bulbs, it is also very important to select high-quality raw materials and production equipment.
