Description

Technical Field

[0001] The utility model relates to an improvement of a cold-resistant lamp strip, in particular to a trichromatic cold-resistant lamp strip. Background Art

[0002] The LED lamp strip is a commonly used landscape lamp, especially the trichromatic lamp strip. When in use, different colors of lighting can be achieved by controlling the light-emitting intensity of the trichromatic lamp strip. However, it generally cannot be used in cold climates, especially when applied to ice sculptures to combine with the ice sculptures to play a role in landscaping. Since the ice sculpture site usually needs to maintain a very low temperature, usually around -20°C, and the service life of general lamp strips will be greatly shortened when used in such a low-temperature environment.

[0003] In a cold-resistant lamp strip in the related art, when it is applied to an ice sculpture, it usually needs to open holes in the ice sculpture. After inserting the lamp strip into the holes, both ends of the holes are sealed with cold-resistant materials, and the heat generated when the lamp strip emits light is used to maintain the normal temperature required for the operation of the lamp strip. However, this will cause heat to accumulate in the holes. Although the normal use of the lamp strip can be maintained, the heat will also cause the ice in the holes to melt, ultimately leading to the instability of the ice sculpture structure and affecting the service life of the ice sculpture. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a trichromatic cold-resistant lamp strip.

[0005] The utility model is realized by adopting the following technical scheme: A trichromatic cold-resistant lamp strip includes a light-emitting part and a supporting part. The supporting part is inserted and fixed in the installation hole on the ice sculpture, and the light-emitting part is fixed on the supporting part.

[0006] The supporting part includes a support strip, a heat insulation pad and a lampshade. An installation groove is formed on the support strip. The light-emitting part is inserted and fixed in the installation groove. The heat insulation pad is fixed at the bottom of the installation groove and abuts against the bottom of the light-emitting part. The lampshade covers the opening of the support strip and is placed above the light-emitting part.

[0007] By adopting the above technical scheme, the light-emitting part is installed on the support strip, and a heat insulation pad is padded between the support strip and the installation hole on the ice sculpture. In fact, the light-emitting part is installed in the installation groove, and a heat insulation pad is padded between it and the installation hole of the ice sculpture. The heat generated when the light-emitting part emits light is blocked by the heat insulation pad, reducing the impact on the ice sculpture and prolonging the melting time of the ice sculpture. At the same time, due to the effect of the heat insulation pad, the heat generated when the light-emitting part emits light is concentrated around the light-emitting part, maintaining the normal temperature required for the operation of the light-emitting part. In this way, it can not only maintain the normal working temperature of the light-emitting part, but also reduce the impact of high temperature on the ice sculpture and reduce the risk of ice sculpture melting.

[0008] Optionally, the lampshade is L-shaped. The long side of the lampshade covers above the light-emitting part, and the short side of the lampshade covers the end of the installation groove.

[0009] By adopting the above technical solution, a pair of lampshades are needed during use. After being enclosed, the long sides of the lampshades abut against each other, and the short sides block both ends of the installation groove, so that the installation groove forms a relatively enclosed space, which can effectively reduce the heat dissipation when the light-emitting part emits light. Furthermore, the heat generated by the light-emitting part is used to maintain the temperature required for the stable operation of the lamp strip, and the luminous life of the light-emitting part in a low-temperature environment can be prolonged.

[0010] Optionally, a plurality of ventilation holes are provided on the short side of the lampshade.

[0011] By adopting the above technical solution, when the internal temperature is too high, ventilation can be carried out through the ventilation holes, and then a relatively reasonable temperature can be maintained. Of course, due to the low external environmental temperature, the diameter of the ventilation holes can be a little smaller, which can not only maintain the required temperature, but also prevent the light-emitting part from being damaged due to excessive temperature.

[0012] Optionally, slots are provided on both sides of the installation groove, and the lampshade is inserted into the slots and fixed in the installation groove.

[0013] By adopting the above technical solution, the lampshade can be installed by plugging, that is, the lampshade is actually detachable, and it can be conveniently replaced when the light-emitting part is damaged.

[0014] Optionally, the slot is a T-shaped groove, and the lampshade is provided with a T-shaped strip adapted to the T-shaped groove.

[0015] By adopting the above technical solution, the lampshade can be installed by plugging, that is, the lampshade is actually detachable, and it can be conveniently replaced when the light-emitting part is damaged.

[0016] Optionally, support legs are provided on the end face of the support strip facing away from the light-emitting part, and the support legs contact the side wall of the installation hole on the ice sculpture.

[0017] By adopting the above technical solution, the support legs support the support strip, thereby reducing the contact between the support strip and the installation hole on the ice sculpture, reducing heat transfer, reducing the possibility of the ice sculpture melting, and prolonging the life of the ice sculpture.

[0018] Compared with the prior art, in the utility model, the light-emitting part of the light strip is installed on the support bar, and a heat insulation pad is placed between the support bar and the installation hole on the ice sculpture. In fact, the light-emitting part is installed in the installation groove, and a heat insulation pad is placed between it and the installation hole of the ice sculpture. The heat generated when the light-emitting part emits light is blocked by the heat insulation pad, reducing the impact on the ice sculpture and prolonging the melting time of the ice sculpture. At the same time, due to the effect of the heat insulation pad, the heat generated when the light-emitting part emits light is concentrated around the light-emitting part, maintaining the normal temperature required for the operation of the light-emitting part. In this way, it can not only maintain the normal working temperature of the light-emitting part, but also reduce the impact of high temperature on the ice sculpture and reduce the risk of the ice sculpture melting.

[0024] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Refer to Figures 1-4, A three-primary-color cold-resistant lamp strip, comprising a light-emitting part 1 and a support part 2. The support part 2 is inserted and fixed in the mounting hole on the ice sculpture, and the light-emitting part 1 is fixed on the support part 2. The light-emitting part 1 can be an ordinary three-primary-color LED lamp strip. The light-emitting part 1 is supported by the support part 2 and will not be in direct contact with the mounting hole. When in use, the heat generated by the light-emitting part 1 is basically not conducted to the mounting hole, thereby delaying the melting speed of the ice sculpture. The support part 2 includes a support bar 21, a heat insulation pad 22 and a lampshade 23. An installation groove 24 is formed on the support bar 21. The light-emitting part 1 is inserted and fixed in the installation groove 24. The heat insulation pad 22 is fixed at the bottom of the installation groove 24 and abuts against the bottom of the light-emitting part 1. The lampshade 23 covers the opening of the support bar 21 and is placed above the light-emitting part 1. The light-emitting part 1 is installed on the support bar 21. A heat insulation pad 22 is placed between the support bar 21 and the mounting hole on the ice sculpture. In fact, the light-emitting part 1 is installed in the installation groove 24, and a heat insulation pad 22 is placed between it and the mounting hole of the ice sculpture. The heat generated when the light-emitting part 1 emits light is blocked by the heat insulation pad 22, reducing the impact on the ice sculpture and prolonging the melting time of the ice sculpture. At the same time, due to the function of the heat insulation pad 22, the heat generated when the light-emitting part 1 emits light is concentrated around the light-emitting part 1, maintaining the normal temperature required for the operation of the light-emitting part 1. In this way, it can not only maintain the normal operating temperature of the light-emitting part 1, but also reduce the impact of high temperature on the ice sculpture and reduce the risk of ice sculpture melting.

[0026] The lampshade 23 can be L-shaped. The long side 231 of the lampshade 23 covers above the light-emitting part 1, and the short side 232 of the lampshade 23 covers the end of the installation groove 24. When in use, a pair of lampshades 23 are required. After being covered, the long sides 231 of the lampshades 23 abut against each other, and the short sides 232 block both ends of the installation groove 24, making the installation groove 24 form a relatively closed space, which can effectively reduce the heat dissipation when the light-emitting part 1 emits light. Furthermore, the heat generated by the light-emitting part 1 emitting light is used to maintain the temperature required for the stable operation of the lamp strip, and the luminous life of the light-emitting part 1 in a low-temperature environment can be prolonged. A plurality of ventilation holes 233 can be formed on the short side 232 of the lampshade 23. So as to facilitate heat exchange with the external environment, and then maintain the temperature balance in the installation groove 24, so that the light-emitting part 1 always maintains an appropriate operating temperature. When the internal temperature is too high, it can ventilate through the ventilation holes 233, and then maintain a relatively reasonable temperature. Of course, due to the low external environmental temperature, the diameter of the ventilation holes 233 can be a little smaller, which can not only maintain the required temperature, but also prevent the light-emitting part 1 from being damaged due to excessive temperature.

[0027] A further solution is to provide slot openings on both sides of the installation groove 24 for installing the lamp shade 23. The lamp shade 23 is inserted into the slot openings and fixed within the installation groove 24. The slot openings are parallel to the installation groove 24. The lamp shade 23 as a whole remains strip-shaped. During installation, the edge of the lamp shade 23 is inserted into the slot openings and slides within the slot openings until the lamp shade 23 completely covers the slot openings. In fact, there are a pair of lamp shades 23 during installation. One lamp shade 23 is inserted from one end of the slot opening, and the short side 232 of the lamp shade 23 contacts one end of the installation groove 24. The other lamp shade 23 is inserted from the other end of the slot opening until the short side 232 of the lamp shade 23 contacts the other end of the installation groove 24. After installation, the ends of the long sides 231 of the lamp shades 23 abut against each other, that is, the long sides 231 of the pair of lamp shades 23 completely cover the installation groove 24, closing the installation groove 24. Thereby, the light-emitting part 1 is in a relatively enclosed working environment, reducing heat dissipation, and further reducing the impact on the ice sculpture. At the same time, the heat is enclosed within the working area. During use, the heat dissipated by the light-emitting part 1 itself can be used to maintain the working temperature of the light-emitting part 1 itself. Together with the function of the heat insulation pad 22, the heat generated when the light-emitting part 1 emits light is concentrated around the light-emitting part 1, maintaining the normal temperature required for the operation of the light-emitting part 1. In this way, it can both maintain the normal working temperature of the light-emitting part 1 and reduce the impact of high temperature on the ice sculpture, reducing the risk of the ice sculpture melting. The lamp shade 23 can be installed in a plug-in manner, that is, the lamp shade 23 is actually detachable, and when the light-emitting part 1 is damaged, it can be conveniently replaced.

[0028] The slot opening is a T-shaped groove 25, and the lamp shade 23 is provided with a T-shaped strip 234 adapted to the T-shaped groove 25. The end face of the support strip 21 facing away from the light-emitting part 1 is provided with support legs 26, and the support legs 26 contact the side wall of the installation hole on the ice sculpture. The lamp shade 23 can be installed in a plug-in manner, that is, the lamp shade 23 is actually detachable, and when the light-emitting part 1 is damaged, it can be conveniently replaced. The support legs 26 prop up the support strip 21, thereby reducing the contact between the support strip 21 and the installation hole on the ice sculpture, reducing heat transfer, reducing the possibility of the ice sculpture melting, and prolonging the lifespan of the ice sculpture.

[0029] Compared with the prior art, in the present utility model, the light-emitting part 1 of the light strip is installed on the support strip 21, a heat insulation pad 22 is provided between the support strip 21 and the installation hole on the ice sculpture, and the light-emitting part 1 is actually installed within the installation groove 24, and a heat insulation pad 22 is provided between the light-emitting part 1 and the installation hole of the ice sculpture. The heat generated when the light-emitting part 1 emits light is blocked by the heat insulation pad 22, reducing the impact on the ice sculpture and prolonging the melting time of the ice sculpture. At the same time, due to the function of the heat insulation pad 22, the heat generated when the light-emitting part 1 emits light is concentrated around the light-emitting part 1, maintaining the normal temperature required for the operation of the light-emitting part 1. In this way, it can both maintain the normal working temperature of the light-emitting part 1 and reduce the impact of high temperature on the ice sculpture, reducing the risk of the ice sculpture melting.

[0030] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
