Description

A water-cooled heat dissipation LED street lamp

technical field

The utility model relates to the field of LED street lamps, in particular to a water-cooled and heat-dissipating LED street lamp.

Background technique

In the prior art, due to the large area of the square, it is necessary to set up high-position LED street lights with super-power to illuminate the whole square. A big problem arises from this, the super-powerful LED street lamp heats up very seriously, and it is easy to burn the LED integrated circuit board and shorten the LED bulb if the heat is not dissipated in time. An existing water-cooled and heat-dissipating LED street lamp has a complex heat-dissipating structure, and a fan and a heat conductor are arranged above the LED integrated circuit board to dissipate heat from the LED integrated circuit board. Because the fan is easily damaged, it is difficult to replace and maintain, which will easily cause the heat dissipation effect to deteriorate and affect the service life of the LED street lamp. The water-cooling tube of this cooling device is S-shaped, and the heat dissipation is relatively slow. Moreover, the LED lamp beads in the lampshade are also heating elements. With the prolongation of the lighting time, the temperature of the sealed lampshade will become higher and higher. However, the water cooling device of this kind of LED street lamp only dissipates heat to the LED integrated circuit board, not to the lampshade. Timely heat dissipation treatment will easily shorten the service life of LED lamp beads.

Therefore, there are defects in the prior art and need to be improved.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

This embodiment provides a water-cooled and heat-dissipating LED street lamp, including a lamp post 10, a lamp holder, a base 11, a water pipe, and a water tank 13. The lamp holder includes: a lampshade 4, and several heat-conducting copper tubes 1 arranged side by side for fixing the heat-conducting The copper plate 2 of the copper pipe 1, the LED integrated circuit board 3, and a number of LED lamp beads 6, the two ends of each heat-conducting copper pipe 1 are respectively connected with a water inlet pipe 801 and a water outlet pipe 701, and the water inlet pipes 801 are in common It is connected to the main water inlet pipe 8, and the water outlet pipes 701 are commonly connected to the main water outlet pipe 7; wherein, the plurality of LED lamp beads 6 are integrated on the LED integrated circuit board 3, and the copper plate 2 is arranged on the LED integrated circuit board 3 Each heat-conducting copper tube 1 is located on the copper plate 2 and is integrated with the copper plate 2; the lamp cap is also provided with four copper pillars 5, and each copper pillar 5 passes through the four corners of the LED integrated circuit board 3 and is connected with the copper plate 2. The copper plate 2 is integrally arranged; the water tank 13 is buried in the ground, the water inlet main pipe 8 and the water outlet main pipe 7 are respectively connected to the water tank 13, and the inside of the water tank 13 is provided with a submersible electric pump 12, and the submersible electric pump 12 and Water inlet main pipe 8 links to each other.

As shown in FIG. 1 , several heat-conducting copper tubes 1 are arranged side by side, and each heat-conducting copper tube 1 is arranged in a hollow shape. Each heat-conducting copper tube 1 is fixed on the copper plate 2, and each heat-conducting copper tube 1 and the copper plate 2 are integrated to simplify the structure, so that the heat dissipation effect of the copper plate 2 and the heat-conducting copper tube 1 can reach the best. A water inlet pipe 801 and a water outlet pipe 701 are respectively connected to both ends of each heat-conducting copper pipe 1 , each water inlet pipe 801 is connected to the water inlet main pipe 8 , and each water outlet pipe 701 is connected to the water outlet main pipe 7 together. The cold water in the water inlet main pipe 8 is distributed to each water inlet pipe 801, and the cold water enters each heat-conducting copper pipe 1 through each water inlet pipe 801. Each heat-conducting copper tube 1 has cold water flowing through it synchronously to take away the heat generated by the LED street lamp. After passing through the heat-conducting copper tube 1, the cold water becomes hot water, and flows out from each water outlet pipe 701 into the water outlet main pipe 7. Compared with the S-type heat pipe, it has only one heat pipe, and the heat dissipation effect is slower, which cannot meet the heat dissipation requirements of super-high-power LED street lights. A plurality of heat-conducting copper tubes 1 are arranged side by side, and the heat dissipation speed is fast and uniform, which can meet the heat dissipation requirements of super-high-power LED street lamps. At the same time, four copper pillars 5 are arranged on the lamp head, and each copper pillar 5 passes through the four corners of the LED integrated circuit board 3 respectively, and the four copper pillars 5 are integrated with the copper plate 2 . In this way, the copper pillar 5 can export the heat in the lampshade 4 and be taken away by the water, reduce the temperature inside the entire lampshade 4 and prolong the service life of the LED lamp bead 6 . Moreover, the four copper pillars 5 are in direct contact with the LED integrated circuit board 3 to accelerate heat dissipation.

As shown in Fig. 2, the water tank 13 for water supply is buried in the ground, and the temperature of the ground is relatively low, so that the temperature of the water used to cool the LED lamp head is kept at a low value, which is beneficial to heat dissipation. The water inlet main pipe 8 and the water outlet main pipe 7 are connected with the water tank 13 respectively. The submersible electric pump 12 is arranged inside the water tank 13, and the submersible electric pump 12 sinks under the water surface, and there is no need to set up a space outside the water tank 13 for placing the water pump, so that the present embodiment is easy to implement and reduces costs. Water outlet main pipe 7 is directly connected with water tank 13, because water flows down from high place, need not be provided with other devices on water outlet main pipe 7. When the submersible electric pump 12 starts, cold water is sent into the lamp holder, and naturally flows into the water tank 13 after passing through the cooling device.

Further, in order to make the turning on and off of the LED street lamp consistent with the turning on and off of the submersible electric pump 12 , an automatic switch 9 for starting or turning off the submersible electric pump 12 is provided at the connection between the water inlet main pipe 8 and the water tank 13 . When the LED street lamp is started, the automatic switch 9 starts the submersible electric pump 12 thereupon; In this way, the submersible electric pump 12 is turned on and off synchronously with the LED street lamp, which is beneficial to save costs.

Furthermore, in order to prolong the service life of the lampshade 4 and maximize the irradiation range of the light, the lampshade 4 is a PC lampshade 4 .

The utility model has a simple structure and can quickly dissipate heat from the LED street lamp.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
