How do table lamps work

Table lamps are generally referred to as electric lamps with a base for use on a table. However, with the advancement of technology, the appearance, and shape of Table lamps have evolved, and gradually desk lamps that can have different levels of brightness have emerged, which are small and delicate, and easy to carry. The main purpose of a Table lamp is to illuminate and facilitate our reading, study, and work. The value of the Table lamp has gone far beyond itself and has even become a work of art. So do you know how a Table lamp works?

Here is the content list:

The main working principle of the Table Lamp

The lamps used in Table lamps are generally led lamps. Table lamps have a special diode inside the bulb, a semiconductor device that forms a PN junction through doping and other means. When the diode's conduction conditions are met, current flows through the Table lamp, releasing energy in the form of light and heat. LEDs are current-controlled, current-type components whose luminous intensity depends primarily on the amount of current passing through them, with a high voltage drop during positive conduction and a certain range of fluctuations of their own. As Table lamp does not have infrared and ultraviolet radiation, the energy consumed is almost all heat, except for the conversion into light energy, which can only be transferred in the form of heat conduction, therefore, when Table Lamp is working, the temperature will rise, but do not worry, this is a normal phenomenon.

The heart of Table Lamp

The core of the Table lamp is a wafer consisting of a P-type semiconductor and an N-type semiconductor with a transition layer between the P-type semiconductor and the N-type semiconductor called a PN junction. In the PN junction of certain semiconductor materials, the injected minority carriers are compounded with most carriers, releasing excess energy in the light, thus converting electrical energy directly into light energy. the PN junction plus reverse voltage, the minority carriers are difficult to inject, so they cannot emit light. When the Table lamp is in positive operation (i.e. positive voltage is applied to both ends) and current flows from the anode to the cathode of the Table lamp's led lamp, the semiconductor crystal emits light of different colors from ultraviolet to infrared, the intensity of the light being related to the current.

These are the Table lamp principles. Various sizes of Table lamps are suitable for use in different locations, depending mainly on the brightness required by the user, the distance to be illuminated, the width of the installation site, etc. With unique lamp design and leading optical applications, we strive to create home lighting and create a comfortable, healthy, and tasteful light environment to make your life simple, pleasant, and more fun.
