Description

High Power LED Lamps

technical field

The utility model relates to the field of LED lighting, in particular to a high-power LED lamp.

Background technique

As an emerging green light source, LED has many advantages such as energy saving and environmental protection, and is increasingly applied to various lighting fields. LED is a solid-state light source that converts electrical energy directly into visible light output. With the continuous development of LED technology, the power of the current LED light source is already very high, which can emit high-brightness light. This high-power LED has been applied to the lighting equipment of various large venues. Although high-power LEDs can emit high-brightness light, limited by technology, the efficiency of converting electrical energy into light energy has not yet reached 100%. At present, the conversion efficiency of high-power LEDs produced by some manufacturers with more advanced technologies can also reach 100%. About 80%, about 20% of the electric energy is still converted into heat energy. If the heat energy cannot be conducted and dissipated from the LED in a timely and effective manner, the service life of the LED will be greatly affected. Therefore, the existing high-power LED lamps will be equipped with various heat dissipation devices to conduct and dissipate the heat in the LED. At present, the heat dissipation equipment used in high-power LED lamps is generally a passive heat dissipation structure composed of many heat sinks. The heat is conducted from the LED lamp board to the base plate of the heat sink, and then to each heat sink, and finally the heat sink dissipates the heat through thermal radiation. This heat dissipation structure can meet the requirements for the heat dissipation effect of LED lamps with low power, but for high-power LED lamps that require ultra-high brightness, the heat dissipation efficiency is seriously insufficient. Due to the low heat dissipation efficiency, a large number of The heat accumulated on the radiator makes it difficult for the heat on the LED to be transmitted to the radiator, which seriously affects the service life of the lamp.

Utility model content

In view of the deficiencies in the above-mentioned prior art, the purpose of this utility model is to provide a high-power LED lamp, which has a very excellent heat dissipation effect and can meet the heat dissipation requirements of the ultra-high-brightness high-power LED lamp.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a high-power LED lamp, including a reflector and an LED light source installed at the center hole of the reflector, characterized in that the LED light source includes a tubular radiator and a sticker A plurality of LED lamp boards installed on the outer surface of the radiator. The radiator has an outer tube and an inner tube nested together. The outer tube and the inner tube are connected to form an integral structure through a plurality of cooling fins.

Preferably, the outer tube is in the shape of a regular prism, and an LED light board is mounted on each side.

Preferably, the inner tube is in the shape of a cylinder or a regular prism.

Preferably, a heat dissipation rib is further provided between the heat dissipation fins, and the heat dissipation rib is extended from the inner side wall of the outer tube and its end is suspended.

Preferably, heat dissipation ribs are further provided between the heat dissipation fins, and the heat dissipation ribs extend from the outer side wall of the inner tube and the ends of the heat dissipation ribs are suspended.

Compared with the prior art, the utility model has the following advantages: by mounting a plurality of LED lamp panels on the outer surface of the tubular radiator, it can provide ultra-high brightness lighting requirements, and of course the heat is also very large, so the radiator is designed as It has an outer tube and an inner tube that are nested together, and the outer tube and the inner tube are connected to form an integral structure through a plurality of cooling fins. After the radiator is designed with this structure, it not only doubles the heat dissipation area of the radiator, but also forms multiple channels in the radiator, such as the passage inside the inner tube, and the formation between the fins, the outer tube and the inner tube. Due to the uneven distribution of heat in these channels, the air in the channels will also be hot and cold, and the air will actively form rapid convection. In this way, the radiator can not only dissipate heat through thermal radiation, but also better dissipate heat through air circulation, so that the heat dissipation effect is increased several times, and the heat on the radiator can be dissipated quickly without forming Heat accumulation can dissipate the heat on the LED better and more efficiently. Therefore, the high-power LED lamp of the present invention has a very excellent heat dissipation effect, and can meet the heat dissipation requirements of the ultra-high-brightness high-power LED lamp.
