Description

lighting fixtures

The present invention relates to a lighting device, in particular to a lighting device that can turn on or off illumination light in a pivoting manner.

Lighting fixtures are installed in indoor spaces to improve the brightness of the environment. Generally used lighting fixtures can be divided into many different types, such as: table lamps, wall lamps, ceiling lamps, wall lamps, table lamps, standing lamps, etc., among which table lamps Lamps are one of the most popular products. Since they can be placed at will, they have become an indispensable lighting fixture at home or in public places.

With the advancement of science and technology, breakthroughs in light-emitting diode processes and technologies, light-emitting diodes, or LEDs for short, have the advantages of low power consumption, long service life, low voltage, etc., and have been widely used in the lighting field. When used in When placed on a table lamp, the feature of being able to place it at will is brought into full play.

Since a push switch is generally installed on the desk lamp to turn on and off the power of the LED lamp, the electronic components of the push switch are visible on the surface of the desk lamp, making the appearance slightly awkward and hindering the overall appearance. In addition, some desk lamps have hidden transmission lines, but the hidden transmission lines must be connected to the power supply circuit and light-emitting components, which limits the adjustment structure of the desk lamp, and generally the structure of the desk lamp is a base A support rod is added to support the lighting fixture, but its structure cannot accommodate stationery.

From the above description, it can be seen that the table lamps currently used have the following shortcomings:

1. The overall appearance is abrupt: A general desk lamp must be equipped with a switch component to transmit power when lighting is needed, and to turn off the power when lighting is not needed to avoid wasting electricity. Currently, the switch components installed on desk lamps are mainly push switches, but The push switch installed on the desk lamp creates an unexpected appearance.

2. Transmission lines will hinder structural changes: Although there are some desk lamp products on the market with hidden transmission lines to provide a simpler appearance, the hidden transmission lines must be connected to the power supply circuit and light-emitting components, so the adjustment structure in the desk lamp cannot cause damage to the transmission lines. This will limit the adjustment and changes of the table lamp structure.

3. Unable to store stationery: A general desk lamp structure only has a support base, a support pole that stands on the support base, and a lamp structure that is mounted on the support pole. There is no storage space in the desk lamp, and it is impossible to store all the objects used for reading or writing. Storage of used stationery.
