Description

LED desk lamp

technical field

The utility model relates to a light source, in particular to a light-emitting diode desk lamp.

Background technique

The first successful invention of the light source for electric lamps is the electric heating wire bulb. Therefore, all kinds of lighting fixture structures have always been based on the installation of electric heating wire bulbs as the light source, including desk lamps used on desks.

However, recently, due to the discovery that energy consumption is seriously exacerbating global warming, countries are striving to develop and promote more energy-saving and environmentally friendly electrical appliances, so that lighting fixtures must also be developed in the direction of the most energy-saving, and traditional electric heating filament bulbs consume too much electricity. With low energy efficiency, people will gradually be replaced by more power-saving light-emitting elements, and light-emitting diodes are currently the latest and most energy-saving light-emitting elements. The light output efficiency per unit of electricity is high, and it is easy to save electricity and increase heat dissipation. It can improve the brightness of the lighting and use it as ambient lighting. Therefore, in response to the lighting equipment developed in the near future, it must be changed to a lamp structure that can install light-emitting diodes. Among the lamps that are often placed in various home or work environments, table lamps are used. The shape is small, and it is most difficult to adjust it into a lamp suitable for light-emitting diodes.

The luminous body installed in the traditional light bulb lamps enables the traditional table lamp to be directly equipped with light-emitting diodes without changing the structure. However, since the light-emitting diodes and the voltage-transformed power supply light-emitting diode circuits are all encapsulated in light-transmitting colloids, they cannot be removed and disassembled. Burning damage can only be discarded as a whole, and it cannot be disassembled, which is not convenient for environmental protection classification and recycling, and will also cause environmental pollution in addition.
