Description

LED lampshade structure

technical field

The utility model relates to an LED lampshade structure, in particular to an LED lampshade structure using light-emitting diodes (LEDs) for lighting.

Background technique

Since the invention of lighting fixtures, the structure, style, usage and lighting effects of electric lamps have undergone significant changes and differences. Of course, their lighting efficacy has also greatly improved.

Analyzing today's lighting fixtures, it can be known that fluorescent tubes are still the mainstay at present, and in order to obtain a good scattering effect of light, the lamps are usually installed at a higher position (such as: the ceiling), but fluorescent lamps emit light using The principle of gas discharge is to accelerate the movement of electrons in the fluorescent tube, generate ultraviolet rays through the gas sealed in the tube, and then emit light through the fluorescent powder coated on the glass tube. Therefore, the fluorescent lamp is often used for six thousand hours. Mercury has been completely absorbed by the tube wall, thus causing the fluorescent tube to lose the ability to discharge smoothly, resulting in the phenomenon of burning the tube. In addition, the lamp is installed on the ceiling, so it is not easy to replace.

In order to improve the problems of short life, high power consumption and difficult replacement of current lighting fixtures, the industry has developed a light-emitting diode (LED) that has a long life, low power consumption and can be replaced without replacement. For example, Taiwan Patent No. M289464 (announcement date: April 11, 2006) discloses a kind of LED lamp, which uses a high-power LED bulb to be installed on an aluminum substrate that has lines and can dissipate heat. However, when the light source of the LED lamp is irradiated on the object, due to the problem of its own manufacturing process, the object to be irradiated will produce layer upon layer of ghost images, hindering the vision and making the user feel uncomfortable.
