A high-power LED lamp with heat dissipation

Abstract

A heat-dissipating high-power LED lamp comprises a shell, a heat sink arranged in the shell, a first mounting surface at the top and / or a second mounting surface at the bottom for mounting a light source of the LED lamp, and the heat sink comprises a heat-dissipating member and a plurality of first heat-dissipating fins arranged in a ring shape on the first mounting surface, the intervals between the first heat-dissipating fins are communicated with each other to form a heat-dissipating cavity, and one end of the first heat-dissipating fins extends outward and protrudes from the shell to form a heat-dissipating port communicated with the heat-dissipating cavity. The one end of the first heat-dissipating fins extends outward and protrudes from the shell to form the heat-dissipating port directly communicated with the heat-dissipating cavity, thereby forming a directional flow path of "hot air flow in the shell, heat-dissipating cavity and heat-dissipating port". By using the physical property of hot air rising, the hot air flow formed in the shell due to heat generated by the light source can naturally flow into the heat-dissipating cavity and then be quickly discharged to the outside through the heat-dissipating port, thereby avoiding the hot air flow from circulating and accumulating in the shell and providing an unobstructed path for high-power heat conduction.

Description

Technical Field

[0001] This utility model relates to the field of LED lamp heat dissipation technology, specifically to a high-power LED lamp with heat dissipation capability. Background Technology

[0002] With the development of LED lighting technology, high-power LED floor lamps of 200W and above are increasingly used in commercial spaces, industrial sites and large home settings. Their advantages of high efficiency, energy saving and high brightness have become the core demand of the market.

[0003] However, high-power LED lights have a high power density, and the LED light source continuously releases a lot of heat when working. Heat dissipation has become a key bottleneck restricting their performance upgrades and market promotion.

[0004] In the existing technology, the heat sink of high-power LED lamps mostly adopts a single heat sink structure design, which has two major defects: First, for the sake of aesthetics, the heat sink is covered by a closed shell, resulting in a limited heat dissipation surface area and insufficient heat exchange efficiency with the air, making it impossible to quickly dissipate the concentrated heat generated by high power; Second, the heat conduction path is single and lacks directional flow and heat dissipation channel design, which makes it easy for heat to circulate and accumulate inside the lamp housing and difficult to efficiently dissipate to the outside.

[0005] This problem of insufficient heat dissipation will trigger a series of chain reactions: it will not only accelerate the light decay of LED light sources and significantly shorten the lifespan of lamps, but also affect the working stability of internal electronic components due to high temperature environment, resulting in a decrease in luminous efficiency and color temperature shift. In severe cases, it may even cause circuit overheating failure, posing safety hazards and failing to meet the long-term stable operation requirements of high-power LED lamps. Utility Model Content

[0006] The purpose of this invention is to solve the heat dissipation problem caused by the low heat exchange efficiency between LED lights and air, and to propose an LED light heat sink and an LED light.

The heat sink comprises: Heat dissipation components; Multiple first heat sinks are arranged in a ring at intervals on the first mounting surface, and the intervals formed between the multiple first heat sinks are interconnected to form heat dissipation channels. One end of the first heat sink extends outward and protrudes from the housing to form a heat dissipation opening, which is connected to the heat dissipation cavity.

[0008] As a further embodiment of this invention, the radiator further includes: Multiple second heat sinks are arranged along the sides of the heat sink; An annular channel is provided on the second mounting surface, and the annular channel is used to install an auxiliary light source for LED lights; Reinforcing ribs are arranged in a ring on the first mounting surface; The third heat sink is arranged along the cavity formed inside the annular channel; The heat sink, reinforcing rib, first heat sink, second heat sink, annular channel, and third heat sink are all integrally formed.

[0009] As a further embodiment of this utility model: the heat sink extends to one side to form a heat sink tail, and the heat sink tail is recessed inward to form a groove.

[0016] The beneficial effects of this invention are as follows: One end of the first heat sink extends and protrudes from the shell to form a heat dissipation vent, and is directly connected to the heat dissipation cavity, forming a directional flow path of "hot airflow inside the shell, heat dissipation cavity, and heat dissipation vent". Utilizing the physical property of rising hot air, the hot airflow generated by the light source inside the shell can naturally flow into the heat dissipation cavity, and then be quickly discharged to the outside through the heat dissipation vent connected to the heat dissipation cavity, avoiding the accumulation of hot airflow in the shell and providing an unobstructed channel for high-power heat conduction.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the accompanying drawings of this application, Figure 3 The red arrow at the location represents a schematic diagram of hot air being discharged.

[0022] Example 1, please refer to Figure 4-5 A high-power LED light with heat dissipation, comprising: Casing 1; Heat sink 2 is disposed inside the housing 1, with a first mounting surface at the top and / or a second mounting surface at the bottom for detachably mounting the light source of the LED lamp; In this application, the heat sink 2 is circular, but it can also be rectangular, triangular, etc.

[0023] Reinforcing rib 23 is fixed in a ring shape on the first mounting surface; The reinforcing rib 23 has a grid-shaped structure and is used to strengthen the surface strength of the heat dissipation component 21; Multiple first heat sinks 24 are fixed to the first mounting surface in a ring-shaped interval, and the intervals between the multiple first heat sinks 24 are interconnected to form heat dissipation channels; Because the first heat sink 24 is placed vertically, there will be a gap between two first heat sinks 24, and multiple first heat sinks 24 will generate multiple gaps, which will be interconnected.

[0024] Multiple second heat sinks 25 are arranged along the sides of the heat sink 21; The second heatsink 25 is also placed vertically, which is the conventional placement method for heatsinks.

[0025] The annular channel 26 is fixed on the second mounting surface; The third heat sink 27 is arranged along the cavity formed inside the annular channel 26.

[0026] Heat sink 2, reinforcing rib 23, first heat sink 24, second heat sink 25, annular channel 26 and third heat sink 27 are all integrally die-cast. Because aluminum alloy has a high heat dissipation coefficient, all of the above are made of aluminum alloy.

[0027] The heat sink 21 extends to one side to form a heat sink tail 22, and the heat sink tail 22 is recessed inward to form a groove, in which a circuit board or the like can be placed.

[0028] The heat dissipation LED lights also include: The light source assembly is installed inside the housing 1 by screws and attached to the first mounting surface and / or the second mounting surface; Its light source component is an LED light source. When the LED light source is attached to the first mounting surface and the second mounting surface, the heat emitted by the LED light source during operation can be conducted to the aluminum alloy in time and then dissipated, thus ensuring the service life of the LED light. The auxiliary light source 5 is installed inside the housing 1 by screws and attached to the annular channel 26; Its auxiliary light source 5 is actually an LED light source, and the annular channel 26 also has a heat dissipation function and will transfer heat.

[0029] The protective shell 7 is also installed on the first heat sink 24 with screws at the end away from the heat sink 2, specifically at the top of the first heat sink 24.

[0030] One end of the first heat sink 24 extends outward and protrudes from the housing 1 to form a heat dissipation opening 10, which is connected to the heat dissipation cavity.

[0031] The light source component and the auxiliary light source share a heat dissipation structure. Hot air flows upward and dissipates outward from the heat dissipation port 10 to dissipate heat.

[0032] The light source assembly includes an upper light source 4 and a lower light source 3. The upper light source 4 is attached to the first mounting surface, and the lower light source 3 is attached to the second mounting surface. The top light source 4 is the main lighting source that emits light from the top. It is indirect lighting, and the light shines on the ceiling and then diffuses and reflects, which improves the lighting of the area that needs to be lit, while also improving the lighting uniformity of the entire space and reducing glare. The lower light source 3 is the main lighting source that emits light from below, providing direct illumination so that the light shines directly onto the area that needs to be illuminated.

[0033] A bracket 9 is also provided between the auxiliary light source 5 and the annular channel 26, and the auxiliary light source 5 is detachably mounted on the annular channel 26 via the bracket 9; In fact, auxiliary light source 5 is a dual-source lighting source. These two sources share a single light-emitting area and serve as auxiliary lighting for downward-emitting light.

[0034] The shell 1 includes an upper shell 11 and a lower shell 12, which are assembled together. The upper shell 11 and the lower shell 12 can be installed and fixed together by means of clips or screws.

[0035] A lampshade is provided on the upper shell 11 and the lower shell 12 at the location of the light source assembly; The lampshade is for protecting the light source.

[0036] The lower light source 3 is ring-shaped, with a circular hole at the center of the ring. The auxiliary light source 5 is located at the circular hole, and the auxiliary light source 5 and the lower light source 3 are on the same plane.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
