Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
The embodiment provides an LED high-power lamp, as shown in fig. 1-3, including an LED light source 1 and a heat dissipation structure disposed on the LED light source 1;
the heat dissipation structure comprises a metal reflector 2 and a metal power supply box 3, wherein the metal reflector 2 is provided with a first contact part in contact with the metal power supply box 3, and the metal power supply box 3 is provided with a second contact part tightly attached to the first contact part; the LED light source 1 is arranged in the metal reflecting cover 2 and is connected with the first contact part in an abutting mode;
the metal power supply box 3 is provided with a first tearing hole group 4 and a second tearing hole group 5 for air circulation; the first tearing hole group 4 is arranged on one side of the metal power supply box 3 close to the metal reflector 2, and the second tearing hole group 5 is arranged on the other side of the metal power supply box 3 far away from the metal reflector 2.
Specifically, the inside of the metal reflector 2 can be used as an accommodating space alone, the metal reflector 2 is provided with a first contact part abutted to the metal power supply box 3, and the LED light source 1 is arranged in the metal reflector 2 and abutted to the first contact part. In the operation process of the LED lamp, heat generated by the LED light source 1 can be conducted to the metal reflector 2 through the first contact part, and natural convection heat exchange and radiation heat exchange are carried out between the air fluid and the metal reflector 2.
Radiative heat transfer is between two objects at different temperatures, with the result that a high temperature object transfers heat to a low temperature object. Because the temperature difference exists between the LED light source 1 and the metal reflecting cover 2, the temperature of the LED light source 1 is higher than that of the metal reflecting cover 2, so that the heat of the LED light source 1 is conducted to the metal reflecting cover 2 in the form of battery waves, and the radiation heat transfer between the LED light source 1 and the metal reflecting cover 2 is realized.
In addition, the metal power supply box 3 is provided with a second contact part tightly attached to the first contact part, so that a part of heat generated by the LED light source 1 can be conducted to the metal power supply box 3 through the first contact part and the second contact part, and natural convection and radiation heat exchange are performed between the air fluid and the metal power supply box 3.
Specifically, the metal power supply case 3 forms a passage for air-fluid flow in a region between the first tear hole group 4 and the second tear hole group 5. During the operation of the power supply, the air fluid can enter and exit the metal power supply box 3 through the first tearing hole group and the second tearing hole group 4, and the density is different due to the internal temperature difference of the fluid, so that the rising buoyancy is formed. That is, when the air fluid gradually rises and contacts the surface of the power module 33, natural convection heat exchange is performed with the power module 33, and the air fluid takes away the heat of the power module 33 and flows out of the metal power box 3 through the second tearing hole group 5, so that the heat dissipation of the power module 33 is realized, and the heat of the power module 33 is reduced.
In one embodiment, the first set of tear-holes 4 is arranged circumferentially around the periphery of the first contact portion. The first tearing hole group 4 is arranged around the periphery of the first contact part, so that the inner wall surface and the outer wall surface of the metal reflector 2 and the system blackness epsilon value of the wall surface of the metal power supply box 3 in the radiation heat exchange process in the whole relative operation space are optimal, and meanwhile, the natural convection coefficient h of the wall surface is also optimal.
In one embodiment, the metal power supply box 3 is formed into a cylindrical shape, and the cylindrical shape facilitates the metal power supply box 3 to be in fit contact with the metal reflector 2. In addition, the first tearing hole group 4 is arranged on the cambered surface of the metal power supply box 3.
In a further embodiment, in order to facilitate the placement of the first set of tear-holes 4, the first set of tear-holes 4 is located in the same plane as the first contact portion.
Specifically, the first tearing hole group 4 and the first contact part are arranged on the same plane, and heat on the surface of the metal reflecting cover 2 can enter the metal power supply box 3 along with air fluid, so that heat conduction of the metal reflecting cover 2 is accelerated, and the heat dissipation performance of the high-power LED lamp is further improved.
In one embodiment, the metal power supply box 3 includes a housing 31, a cover plate 32 detachably connected to the housing 31, and a power supply module 33; the housing 31 is provided with a mounting bracket 6 for mounting the power module 33, and the mounting bracket 6 is fixed with the housing 31 through a support rod 7 and forms a gap with the housing 31.
Specifically, the first contact portion is disposed at the bottom end of the housing 31 and attached to the metal reflector 2, and the mounting bracket 6 is disposed between the first contact portion and the power module 33. When the LED lamp works, the power module 33 and the LED light source 1 both generate certain heat, and if the power module 33 is in direct contact with the LED light source 1, the temperatures of the power module 33 and the LED light source 1 are increased to different degrees, so that the heat dissipation effect of the LED lamp is influenced. The support rod 7 of this embodiment is made of a heat-insulating material, the support rod 7 jacks up the mounting bracket 6, and the power module 33 mounted on the mounting bracket 6 is not in direct contact with the LED light source 1, so that heat between the power module 33 and the LED light source 1 cannot be conducted with each other. The heat dissipation stability of the LED lamp is ensured. In addition, a sufficient natural convection space is formed between the first contact part and the power module 33 through the support rod 7, which is beneficial to air flow and enhances convection heat transfer.
In one embodiment, the metal power supply box 3 includes a fixing seat 8, and the fixing seat 8 is disposed in the metal power supply box 3; the metal reflecting cover 2, the metal power supply box 3 and the fixed seat 8 are fixed through fasteners. Through fixing base 8, not only increased the heat conduction area between metal reflector 2 and the metal power supply box 3 for heat conduction efficiency, still make the connection stability between metal reflector 2 and the metal power supply box 3 strengthened.
Specifically, the fixing base 8 may be made of metal or plastic. The material of the fixing base 8 can be selected according to actual needs, and is not limited herein.
As fine gaps and holes with uneven surfaces are generated when the LED light source 1 and the metal reflecting cover 2 are contacted with each other, the heat transfer contact resistance is increased, the heat transfer is blocked, and the heat dissipation performance of the lamp is low.
In order to improve the heat dissipation performance, in an embodiment, a heat conduction layer may be disposed between the contact portions of the LED light source 1 and the metal reflector 2. The heat conduction layer is formed by the following specific steps: the gaps are filled with a thermal interface material with high thermal conductivity to form a heat conduction layer, air in the gaps is exhausted, and an effective heat conduction channel is established between the LED light source 1 and the metal reflector 2. By adopting the mode, the thermal contact resistance between the LED light source 1 and the metal reflecting cover 2 can be greatly reduced, and the heat conduction of the LED light source 1 is accelerated.
In one embodiment, the metal reflector 2 is fixed with a light-transmitting cover 9, and the light-transmitting cover 9 is arranged outside the LED light source 1 as a protective cover.
According to the embodiment, the heat generated by the LED light source 1 in the present application scheme can be dissipated by the metal reflector 2 and the metal power supply box 3 connected to the metal reflector 2. And because the metal power supply box 3 is provided with the first tearing hole group 4 and the second tearing hole group 5 for air circulation, the heat exchange effect between the air fluid and the metal power supply box 3 can be enhanced. The LED lamp structure is good in heat dissipation performance and simple in structure, and the cost for producing the lamp is reduced.
