Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diodes, in particular to an environmentally friendly light emitting diode. Background Art

[0002] Like ordinary diodes, light-emitting diodes (LEDs) consist of a PN junction and exhibit unidirectional conductivity. When a forward voltage is applied to the diode, holes injected from the P region into the N region and electrons injected from the N region into the P region recombine with electrons in the N region and holes in the P region within a few microns near the PN junction, generating spontaneous fluorescence. This emission process primarily corresponds to the spontaneous emission of light. The energy states of electrons and holes in different semiconductor materials vary, and the amount of energy released when electrons and holes recombine varies. The greater the energy released, the shorter the wavelength of the emitted light.

[0003] After searching, the patent document with application number CN202122174328.3 discloses an environmentally friendly light-emitting diode, including a base box and a lampshade connected upper and lower. A light-emitting chip is provided in the lampshade, and the light-emitting chip is connected to a positive pin and a negative pin extending through the base box. A photovoltaic panel is horizontally provided at the bottom end of the outer side of the lampshade, and a micro battery is provided in the base box. The micro battery is electrically connected to the photovoltaic panel and the light-emitting chip.

[0004] Although the above patent document reduces energy consumption and achieves the purpose of environmental protection by providing photovoltaic panels and micro batteries to power the device, and protects the positive and negative pins by providing protective covers to reduce the possibility of pin breakage, the lampshade is fixed to the base box. When the light-emitting chip inside is damaged and needs to be replaced, it is inconvenient to remove the lampshade from the base box, and the time required is long. Therefore, an environmentally friendly light-emitting diode is proposed. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0014] 1. When the device is in use, the lampshade can be pressed to drive the second connecting ring to slide into the first rectangular groove, and the connecting ring drives the annular plate to move into the first rectangular groove. The spring contracts until the rectangular plate slides out of the rectangular groove. Then the lampshade is rotated to drive the rectangular plate to slide in the second annular groove until the rectangular plate is rotated to the rectangular opening. The lampshade is removed, and the replacement of the lampshade is more convenient and takes less time.

[0015] 2. When the device is in use, the protective cover can be placed on the positive and negative pins outside the lampshade to protect the positive and negative pins from damage and extend their service life. BRIEF DESCRIPTION OF THE DRAWINGS
