I. Introduction

In daily life, table lamps are indispensable lighting companions. Have you ever been curious about the manufacturing processes and production configurations behind them? Among them, the injection molding process of lighting accessories plays a crucial role, as it is a key step in transforming scattered components into finished table lamps. Next, let's explore the manufacturing processes and production configurations behind table lamps together.

II. Composition of Simple Table Lamp Accessories (Mainly Made of Plastic)

Lamp Head Section:Bulb: LED bulb;  Plastic Shade

Lamp Pole Section: Plastic lamp pole

Base Section: Plastic base. Some bases may also have functional components, such as:Switch: Used to control the on and off of the table lamp. Common types include push-button switches, rotary switches, and touch switches.Dimmer: If the table lamp has a dimming function, a dimmer will be installed on the base or the lamp pole, which can adjust the brightness of the light to meet the lighting requirements in different environments.

Power Supply Related Section: Power cord

III. Manufacturing Processes Involved in Each Accessory

1. Bulb Manufacturing Process:For LED bulbs, the main processes are LED chip packaging and assembly.

LED Chip Manufacturing: Through semiconductor manufacturing processes, operations such as photolithography, epitaxial growth, and doping are carried out on the substrate material to grow and etch out a semiconductor structure with a light-emitting function.

Chip Packaging: The manufactured LED chips are packaged with transparent packaging materials (such as epoxy resin, etc.) to ensure good adhesion between the chips and the packaging materials without bubbles or other defects, while connecting the electrodes properly for power-on and light emission.

Assembly into Bulb: The packaged LED chips are assembled together with heat dissipation components, driving circuits, etc., and then installed into the bulb shell. The shell can be fixed by injection molding or bonding processes.

2. Plastic Shade Manufacturing Process: Mainly adopts injection molding and vacuum forming processes.

3. Plastic Lamp Pole and Base Manufacturing Process: Injection molding process is adopted.

4. Switch Manufacturing Process (Push-Button Switch):The outer shell is manufactured by injection molding process, and then the internal metal contacts, springs and other parts are manufactured by machining processes. Finally, they are assembled together.

5. Dimmer Manufacturing Process:If the table lamp has a dimming function, the dimmer is manufactured as follows: The outer shell is manufactured by injection molding process, and the internal part requires a series of electronic circuit manufacturing processes to achieve the dimming function.

6. Power Cord Manufacturing Process:The metal raw materials (such as copper, aluminum, etc.) are drawn into wire filaments of the required thickness by the wire drawing process. Then, the wire filaments are twisted together by the stranding process to form a core wire. Finally, the insulation layer coating process is used to coat the core wire with insulating materials (such as polyvinyl chloride, etc.) to manufacture an insulated wire.

IV. Required Production Configurations in the Factory

1. Bulb Production Stage:

For LED bulbs, the factory needs to be equipped with the following equipment:

Epitaxial Growth Equipment: Used to grow semiconductor structures.

Photolithography Equipment: Used to carry out photolithography processes.

Etching Equipment: Used to etch semiconductor structures.

Packaging Equipment: Such as automatic dispensing machines, curing furnaces, etc., used to carry out packaging operations.

Assembly Equipment: Used to assemble the packaged chips with other components into bulbs.

2. Plastic Shade Production Stage:

 Injection Molding Machine: Used to produce plastic shades through injection molding processes. 

Mold Making Equipment (such as CNC milling machines, EDM machines, etc.): Used to make molds required for injection molding. If vacuum forming process is involved in shade production, a vacuum forming machine also needs to be equipped.

3. Plastic Lamp Pole Production Stage: 

 Injection Molding Machine: Used to process plastic raw materials into plastic lamp poles that meet the requirements. 

Mold Making Equipment: Used to make injection molds.

4. Plastic Base Production Stage: 

 Injection Molding Machine: Used to transform plastic raw materials into plastic bases of various shapes. 

Mood Making Equipment: Used to make injection molds.

5. Switch Production Stage: 

 Injection Molding Machine: Used to manufacture the outer shell of the switch. 

Metal Machining Equipment (such as lathes, milling machines, drill beds, etc.): Used to manufacture the internal metal contacts, springs and other parts of the switch.

6. Dimmer Production Stage: 

 Injection Molding Machine: Used to manufacture the outer shell of the dimmer. 

Electronic Circuit Manufacturing Equipment: Used to achieve the dimming function.

7. Power Cord Production Stage: 

 Wire Drawing Machine: Used to draw wire filaments of the required thickness. 

Stranding Machine: Used to twist wire filaments into a core wire. 

Extrusion Machine: Used to coat the core wire with insulating materials to form an insulated wire.
