Description

LED lighter having natural air-cooled heat-dissipating ventilation channel {LED lighter having air channel}

The present invention relates to an LED lamp having a natural air-air-cooled heat-dissipating ventilation channel, and more particularly, after the natural air introduced from the air inlet formed under the street lamp post passes through the ventilation channel of the lamp post, The present invention relates to an LED lamp having a natural air air-cooled heat-dissipating ventilation channel that can radiate heat generated by a heat sink in contact with a PCB substrate through natural air-air cooling.

In general, the street lamp is installed on the road, such as people and vehicles pass through the light to facilitate the walk and the traffic of the vehicle at night. Lighting lamps such as halogen or mercury lamps are used for street lamps. These lamps have a short lifespan and have to be replaced periodically, requiring considerable cost and effort for maintenance and repair. Therefore, in recent years, high power LED lamps that use less power and have better lighting performance have been used. High-power LED lamps have a long service life and have superior brightness than general halogen or mercury lamps, and have the advantage of saving energy by remarkably reducing the power used.

However, high-power LED lamps such as LED lamps generate high heat when used, and high heat affects not only high-power LED lamps but also peripheral components, causing problems or shortening the lifespan. Therefore, a separate cooling device for cooling the high heat generated from the high power LED lamp is provided in the lamp. Although many light emitting diode lighting apparatuses having various cooling means have been known, they are generally complicated in structure, expensive, and often have a problem of failure. To solve this problem, light emitting diode lighting apparatuses using various cooling apparatuses are known. It is.

Conventional LED lamp cooling device is provided with a plurality of heat sinks to cool the high heat generated in the high-power LED lamp on the back of the LED fixed circuit board. The heat sink has a configuration in which a plurality of heat dissipation fins are integrally formed on a base formed in a plate shape, and the high heat LED lamp is cooled by absorbing and dissipating high heat generated from the high power LED lamp by a heat sink. However, the cooling by the heat sink is simply transferred heat from the high power LED lamp to the heat sink by the heat transfer performance of the heat sink material, and the heat absorbed by the heat sink is radiated by heat exchange with the air contacting the plurality of heat sink fins, so the LED lamp and the heat The heat exchange performance between the sinks is very low, so the LED lamp cannot be cooled down quickly.Therefore, the LED lamp is overheated.To increase the cooling efficiency, the number of heat sinks must be increased and the number of heat sink fins must be increased. It is limited and it is difficult to further increase the cooling performance.

Therefore, it is impossible to sufficiently cool the high heat of the high power LED lamp, and thus the problem of causing the high power LED lamp and the peripheral parts to fail and shorten the life due to overheating cannot be completely solved. In addition, light fixtures using light emitting diodes (LEDs) have the characteristics of higher energy efficiency, longer lifespan, and no emission of contaminants than other light fixtures (fluorescent lamps, mercury lamps, etc.). . In luminaires that use light emitting diodes (LEDs), they typically maintain around 60 ° C when rated current flows through the light emitting diodes (LEDs) .However, when more than the rated current flows, the light emitting diodes (LEDs) generate heat due to high temperatures. ) Is often broken. In the light emitting diode (LED), when the current flows, both ends of the light emitting diode (LED) basically have a constant voltage characteristic, but the voltage increases very minutely as the current increases, and when the current increases above a certain limit, the amount of heat generated As the sharp rises, there is a problem in that the light emitting diode is damaged due to overheating.

The present invention has been made in order to solve the above problems, the natural air introduced from the air inlet formed in the lower portion of the street lamp post passes through the ventilation channel of the lamp post, and then passes through the ventilation channel of the lamp post to contact the PCB substrate. The heat generated from the PCB substrate can be radiated by natural air air cooling as it is transferred to the heat sink, which is simpler in structure and reduced in area and weight compared to the conventional LED lamp cooling system. It is very economical and practical to extend the lifespan of lighting fixtures with excellent cooling function. When the LED lighting device using the LED lamp cooling device of the present invention is used as a street lamp, a security lamp or a tunnel lamp, a light emitting diode of the lighting device ( High heat generated from the LED) by the cooling apparatus of the present invention By according to the dance cooling efficiency is increased, and reduces the failure there is provided a luminaire, which can increase the life of the luminaire. The present invention is excellent in heat exchange performance, heat exchange with a high power LED lamp is made quickly and efficiently, and by making a quick and efficient heat dissipation can increase the cooling efficiency and performance of the high power LED lamp, thereby high power LED by overheating It is an object of the present invention to provide a cooling device such as a high power LED lamp that can prevent the failure of the lamp and the peripheral parts and shorten the life.

The present invention is a natural air air-cooled type heat generated from the heat sink in which the natural air flowing from the air inlet formed in the lower portion of the street lamp post passes through the ventilation channel of the street lamp post and then passes through the lamp lamp ventilation channel to contact the PCB substrate. The present invention relates to an LED lamp having a natural air-cooled heat-dissipating ventilation channel that can radiate heat.

Compared with the conventional LED lamp cooling device, the LED lamp of the present invention has a simple structure, reduced area and weight, and excellent natural air air-cooled cooling function by natural air circulation, thereby extending the life of lighting equipment. When the light emitting diode (LED) lighting device using the LED lamp cooling device of the present invention is used as a street lamp, a security lamp, or a tunnel lamp, high heat generated from the light emitting diode (LED) of the lighting device is cooled according to the present invention. As the device is lowered, the cooling efficiency is increased and the occurrence of failure is reduced, thereby increasing the use time of the luminaire.

The natural air air-cooled heat-dissipating ventilation channel is an air inlet 110 formed in the lower portion of the lower street lamp (100-1) so that the natural air is introduced; Street lamp prop 100, 100-1 so that the natural air introduced from the air inlet 110 of the street lamp lower column 100-1 can penetrate to the natural air air-cooled heat-dissipating ventilating hole 50 of the LED lamp 300. Ventilation channel 120 of the street lamp post (100, 100-1) is formed to penetrate the interior of the; Ventilation channel 220 of the lamp post 200, which is formed to penetrate the interior of the lamp post 200 so that natural air passing through the ventilation channel 120 of the street lamp post 100, 100-1 can pass therethrough. ); And the natural air passing through the ventilation channel 220 of the lamp post 200 flows into the cases 10 and 20 of the LED lamp 300 and then into the cases 10 and 20 of the LED lamp 300. Natural air flows into the upper part of the heat sink 30 mounted inside the LED lamp case, and then cools the heat generated from the PCB board 80, and then the natural air air-cooled heat radiation vent formed on the side of the LED lamp case. Natural product, characterized in that made through the ventilation hole 50 of the LED lamp case to pass through the entrance hole 50 to the outside of the LED lamp case to discharge the heat generated from the PCB board 80 by natural air-air cooling LED light with air-cooled heat-dissipating ventilation channels.
