Description

Technical Field

[0001] The utility model relates to the technical field of light-emitting structures, in particular to a rare earth ion doped light-emitting structure and an LED lamp containing the same. Background Art

[0002] Rare earth ions are widely used in the field of LED lighting. By doping rare earth ions into LED materials, the emission wavelength and color of the LED can be changed. For example, by doping trivalent rare earth ions (such as erbium, ytterbium, etc.) into gallium nitride (GaN) materials, the manufacture of white light LEDs can be achieved. By doping with different rare earth ions, the color temperature of the LED can be adjusted. For example, doping with trivalent erbium ions can make the LED emit warm light, while doping with trivalent ytterbium ions can make the LED emit cool light. Light strips doped with rare earth ions are mostly used in LED lamps. By doping with light strips doped with rare earth ions, LED lamps can emit light of different colors.

[0003] However, the light strips doped with rare earth ions may decompose due to water in a humid environment or after contact with water, resulting in reduced brightness. Most existing outdoor LED lamps only have an LED lampshade as protection. When the LED lampshade is damaged due to external environmental reasons, water molecules in the external environment will follow the air into the lampshade and adhere to the surface of the light strip, causing damage to the light strip. For this reason, we have introduced a rare earth ion doped light-emitting structure and an LED lamp containing the same. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, four groups of L-shaped positioning plates are fixedly connected to the upper end of the mounting seat, and elastic soft pads are fixedly connected to the inner sides of the L-shaped positioning plates. The rare earth ion light strips are positioned by the four groups of L-shaped positioning plates, and the rare earth ion light strips are clamped by the elastic soft pads on the inner sides of the L-shaped positioning plates.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: after the rare earth ion light strip is installed on the upper end of the mounting base, the light-transmitting protective cover is installed on the upper end of the mounting base.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] A rare earth ion doped light emitting structure includes a rare earth ion light emitting light bar 2. By doping rare earth ions into LED materials, the light emission wavelength and color of the LED can be changed, thereby forming a rare earth ion light emitting light bar 2. For example, by doping trivalent rare earth ions (such as erbium, ytterbium, etc.) into gallium nitride (GaN) materials, the manufacture of white light LEDs can be realized. The rare earth ion light emitting light bar 2 is movably mounted on the upper end of a mounting base 1. A light-transmitting protective cover 9 is movably mounted on the upper end of the mounting base 1 through screws 6. The light-transmitting protective cover 9 can protect the rare earth ion light emitting light bar 2. At the same time, the light emitted by the rare earth ion light strip 2 is dissipated outward. Heat dissipation holes 7 are provided on both sides of the light-transmitting protective cover 9. The heat generated by the rare earth ion light strip 2 is dissipated outward through the heat dissipation holes 7. A guide groove 16 is provided at one end of the heat dissipation hole 7. A sealing plate 13 is movably connected in the guide groove 16. A groove 15 is provided in one side of the sealing plate 13. A hook is provided in the groove 15. The sealing plate 13 is connected to the trigger mechanism through the hook in the groove 15. When the trigger mechanism is in a humid environment, the trigger mechanism is started and the sealing mechanism blocks the heat dissipation hole 7.

[0022] Embodiment 2:

[0023] On the basis of Example 1, in order to make the air in a humid state, the blocking plate 13 can be closed to block the heat dissipation hole 7, four groups of L-shaped positioning plates 3 are fixedly connected to the upper end of the mounting seat 1, and the inner side of the L-shaped positioning plate 3 is fixedly connected with an elastic soft pad 4, the rare earth ion light strip 2 is positioned by the four groups of L-shaped positioning plates 3, and the rare earth ion light strip 2 is clamped by the elastic soft pad 4 on the inner side of the L-shaped positioning plate 3, a spring 8 is fixedly connected in the guide groove 16, and the other end of the spring 8 is fixedly connected to the blocking plate 13, and both ends of the mounting seat 1 are fixedly connected with mounting plates 5, and the trigger mechanism includes a water-soluble trigger rope 10, and the material of the water-soluble trigger rope 10 is polyvinyl alcohol. One end of the hair rope 10 is movably connected to the fixing hook 11, and the other end extends into the guide groove 16 and is movably connected to the groove 15. The fixing hook 11 is fixedly connected to the light-transmitting protective cover 9. One side of the water-soluble trigger rope 10 is in contact with the guide wheel 14. The guide wheel 14 can guide the water-soluble trigger rope 10. When the water-soluble trigger rope 10 comes into contact with water molecules, since the water-soluble trigger rope 10 is made of water-soluble material polyvinyl alcohol, the water-soluble trigger rope 10 will melt after contacting the water molecules. When the water-soluble trigger rope 10 melts, the blocking plate 13 moves outward along the guide groove 16 under the elastic force of the spring 8 until the blocking plate 13 completely blocks the heat dissipation hole 7.

[0024] The guide wheel 14 is fixedly connected to the light-transmitting protective cover 9, and a lever 17 is fixedly connected to one side of the blocking plate 13. The lever 17 passes through the slide groove 12 and extends out of the light-transmitting protective cover 9. When the operator needs to reopen the heat dissipation hole 7, a new water-soluble trigger rope 10 is connected to the fixed hook 11 at one end. After the blocking plate 13 is pushed back into the guide groove 16 by the lever 17, the other end of the water-soluble trigger rope 10 is extended into the guide groove 16 and connected to the groove 15.

[0025] Working principle: when in use, it can be installed in the lamp through the mounting plates 5 connected at both ends of the mounting base 1. After the installation is completed, the rare earth ion light strip 2 is inserted between the four groups of L-shaped positioning plates 3. The elastic soft pad 4 connected on the inner side of the L-shaped positioning plate 3 can clamp the rare earth ion light strip 2. After the rare earth ion light strip 2 is installed, the light-transmitting protective cover 9 can be installed on the upper end of the mounting base 1 through the screws 6. After the installation is completed, the lampshade of the lamp can be closed. When the lampshade of the lamp is broken, when it is raining outside, water molecules will follow the air into the lampshade of the lamp. When the water-soluble trigger rope 10 comes into contact with the water molecules, since the water-soluble trigger rope 10 is made of water-soluble material polyvinyl alcohol, the water-soluble trigger rope 10 will melt after contacting the water molecules. After the water-soluble trigger rope 10 melts, the sealing plate 13 moves outward along the guide groove 16 under the elastic force of the spring 8 until the sealing plate 13 completely blocks the heat dissipation hole 7.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
