Next, referring to FIGS. 4 to 5, the temperature of the refrigerant according to the structure of the irrigation pipe 10 and the operation of the LED lamp 30 and the first heat pipe being the first metal member 20 will be described. Let's examine the temperature distribution of.

4A and 4B are front cross-sectional views and side cross-sectional views of the watering pipe 10 including the first heat pipe, which is the first metal member 20, and FIG. 5 is a temperature (a) of the refrigerant for each section of the watering pipe 10. And a temperature b of the first heat pipe that is the first metal member 20.

Referring to the drawings, the watering pipe 10 of the present invention is a pipe having a hollow portion 12 therein while having a predetermined length.

In addition, the watering pipe 10 may have a structure in which both ends thereof are sealed as shown in the drawing.

In addition, the first metal member 20 is inserted into the watering pipe 10.

The first metal member 20 may be formed of a metal having excellent thermal conductivity, for example, a metal such as aluminum (Al), gold (Au), silver (Ag), copper (Cu), or the like.

In addition, the first metal member 20 may be a hollow one, such as a heat pipe, but may be a rod-shaped one filled therein.

In FIG. 4 and FIG. 5, the first heat pipe is applied as an example of the first metal member 20, and the first heat pipe uses the same reference numeral 20 as the first metal member.

The first heat pipe 20 has a structure in which both sides are sealed while the inside is hollow like the watering pipe 10 and is made of a material having excellent heat transfer.

The first heat pipe 20 is heated by using latent heat that is accompanied when the working fluid 21 circulating in the closed vacuum space therein continuously undergoes a phase change (evaporation and condensation) of the liquid-vapor period. By moving, it exhibits breakthrough performance compared to conventional heat transfer equipment using a single-phase working fluid.

The LED lighting lamp 30 is installed on the outer circumferential surface of the watering pipe 10 in the state of filling the refrigerant of the.

In this state, when the LED lights 30 are turned on, heat is generated from the LED lights 30, and the heat is transmitted to the watering pipe 10 in a portion in direct contact with the LED lights 30. The refrigerant is delivered to one side of the first heat pipe 20. Therefore, section A of FIG. 5 forms the highest temperature of the refrigerant.

The heat transferred to one side of the first heat pipe 20 moves to the other side of the first heat pipe within a short time. Due to the characteristics of the first heat pipe, the entire heat distribution is even, and the heat is transferred to the refrigerant. Most of the heat is cooled in the refrigerant, and some heat dissipation through the water pipe (10).

In FIG. 5, graph (a) shows the refrigerant temperature in section A to section C of the irrigation pipe 10, and the refrigerant temperature in section A of the irrigation pipe 10 is in contact with the LED lamp 30. With the highest temperature distribution, the further away from the LED light 30, the lower the refrigerant temperature. (Solid line display)

In addition, the graph (b) shows the first heat pipe temperature in sections A to C of the watering pipe 10. Since the heat conduction is performed from one side of the first heat pipe to the other within a short time, Has a constant temperature distribution over all sections (dotted lines)

On the other hand, the present invention is provided with a buffer member of the rubber material in the LED light 30, the buffer member is deformed according to the temperature rise and fall inside the LED light 30, the amount of change in the pressure generated inside the LED light 30 It can also be configured to minimize this.

Examples of the buffer member include a buffer dropper 71 of FIG. 6, a buffer tube 72 of FIG. 7, and a buffer pad 73 of FIG. 8.

The pressure change amount is, for example, a value obtained by subtracting the internal pressure of the LED lamp 30 shown in FIG. 6A from the internal pressure of the LED lamp 30 shown in FIG. 6B or 6C. . This pressure difference is determined by determining the degree of crush of the rubber bag of the buffer dropper 71 shown in FIG. 6 or by determining the amount of crushing of the buffer tube 72 shown in FIG. 7 or by the buffer pad 73 shown in FIG. It can be determined by looking at the degree of curvature of.

This will be described in more detail with reference to FIGS. 6 to 8.

6 to 8 are exemplary embodiments of a cross-sectional view of the LED lamp 30 showing the operating state of the buffer member.

First, referring to FIG. 6, a cutout 70 formed by cutting a part of the lamp case 31 is formed. A buffer dropper 71 in the form of a dropper is formed in the cutout 70.

That is, one side of the buffer dropper 71 in the form of a pipe while having an open structure to face the outside of the lamp case 31, the other side of the buffer dropper 71 in the form of a rubber pocket (rubber pocket) The case 31 is configured to face the inside.

As described above, the state in which the air of a predetermined pressure and temperature in the LED light 30 is present in the first state of the LED light 30, the buffer dropper 71 as shown in (a) of Figs. The rubber pocket of the), the buffer tube 72 and the buffer pad (73) in the form of this.

When the temperature inside the LED light 30 increases in the state as shown in FIG. 6A, the rubber bag of the buffer dropper 71 is crushed as compared with FIG. 6A, as shown in FIG. 6B. 30) When the temperature inside decreases, the rubber pouch of the buffer dropper 71 is inflated as compared with FIG. 6 (a) as shown in FIG.

More specifically, in the state as shown in Figure 6 (a) the temperature of the interior of the LED lamp 30 is raised, the molecular movement of the air in the lamp case 31 is active, the volume is increased, thereby the lamp case 31 The pressure in) rises. The elevated pressure in the lamp case 31 mostly acts toward the soft rubber bag, and the rubber bag is deformed. That is, as shown in (b) of FIG. 6, the shape of the rubber bag is distorted, and the air in the rubber bag escapes to the outside.

In addition, when the temperature inside the LED lamp 30 decreases in the state as shown in FIG. 6A, the molecular motion of the air in the lamp case 31 is reduced, thereby reducing the volume, and thus, in the lamp case 31. The pressure drops. As the pressure in the lamp case 31 decreases, the collapsed rubber bag expands as shown in FIG. 6C, and outside air flows into the rubber bag.

In addition, as another example of the buffer member, there is a straight buffer tube 72, in order to install the buffer tube 72, as shown in FIG. An incision 70 was formed on one side and the other side of the.

When the temperature inside the LED lamp 30 rises in the state as shown in FIG. 7A, the pressure in the lamp case 31 rises. This elevated pressure mostly acts toward the soft buffer tube 72, so that the air in the buffer tube 72 is released to the outside as the buffer tube 72 is distorted as shown in FIG.

In addition, when the temperature inside the LED lamp 30 decreases in the state as shown in FIG. 7A, the pressure in the lamp case 31 drops. As a result, the deformed buffer tube 72 expands as shown in FIG. 7C, and external air flows into the buffer tube 72.

As another example of the shock absorbing member, there is a shock absorbing pad 73.

In the present invention, as shown in FIG. 8, after cutting a part of the lamp case 31 to form the cutout 70, the inner surface of the lamp case 31 to cover the cutout 70. The buffer pad 73 was comprised in the.

When the temperature inside the LED lamp 30 rises in the state as shown in FIG. 8A, the pressure in the lamp case 31 rises. This increased pressure mostly acts toward the soft buffer pad 73 so that the buffer pad 73 is bent outward as shown in FIG.

In addition, when the temperature inside the LED lamp 30 decreases in the state as shown in FIG. 8A, the pressure in the lamp case 31 drops. Accordingly, the buffer pad 73 is bent inward.

 The cause of the increase in the temperature of the LED lamp 30 in the above is due to the heat emitted from the LED 33 itself or the increase of the external temperature.

As such, even if the temperature inside the LED lighting 30 rises and falls, most of the pressure change is minimized by the cushioning member, that is, the rubber bag, the buffer tube 72, or the buffer pad 73 of the buffer dropper 71. The sealing between the 31 and the protective cover 34 can be maintained for a long time.
