Description

LED street light that has a heat discharge function {LED street lamp that have a heat discharge functions}

The present invention relates to an LED street light having an LED lamp installed in the luminaire as a light source, the LED street light having a heat discharge function configured to efficiently discharge heat generated from the LED of the luminaire. .

As is well known, a lot of lighting devices using LEDs have recently been developed, and one of them is a reality in which street lamps using LEDs have been developed and commercialized.

In general, halogen lamps, fluorescent lamps, and mercury lamps, which are used as light sources in street lights, have a short lifespan, and thus have a disadvantage in that they require a lot of maintenance costs, and also cause environmental pollution due to disposal.

In order to solve these shortcomings, a street light or other lighting fixture using LED as a light source is disclosed. As described above, a street light or other lighting fixture using LED as a light source consumes less energy than a halogen lamp, a fluorescent lamp, or a mercury lamp. Although there is an advantage that can be reduced, the LED as a light source generates a high heat when emitting light, which is a great factor to shorten the life of the LED and at the same time greatly reduces the illuminance of the LED.

In other words, when the LED emits light, it can be used for about 6 ~ 70,000 hours when it is maintained under the optimum temperature of 70 degrees, but when it is kept above the proper temperature, it is reduced to about 2000 hours when the LED is used as a light source. Street lamps or other luminaires shorten the lifespan and low illumination has a disadvantage in that a high cost for maintenance.

In addition, when the internal space of the luminaire is simply opened to dissipate the heat of the LED, rainwater flows in, and foreign matter such as dust or insects (day) enters the LED, thereby reducing the illumination of the LED or causing a failure. It will lead to problems that shorten the life.

The present invention devised in view of the above problems is to extend the life of the LED by quickly discharging the heat generated from the LED in the configuration of the lamp of the street lamp using the LED, very simple installation and configuration It is possible to efficiently and circulate the air to dissipate the heat of the LED, to prevent rainwater from entering in the rain through the vent, and to prevent the inflow of foreign substances such as dust or insects (day) as much as possible The purpose is to provide an LED luminaire configured to

The present invention for achieving the above object in the configuration of the LED streetlight luminaire, to install a vent on the bottom surface of the main body connected to the internal space in which the light source of the LED is installed, the vent is configured in a container shape narrow width straight It is configured to prevent the inflow of rainwater during rainy weather and effectively prevent the inflow of foreign substances such as dust and worms while allowing the air to flow smoothly and exhaust the air. It is characterized by that.

According to the present invention, the air inside the luminaire is circulated due to convection caused by the circulation of the wind or the increase in temperature, and the LEDs are circulated evenly to the rear surface of the substrate on which the LED is installed as well as the heat generated from the light source using the LED. And since the heat generated from the substrate is effectively discharged to prevent shortening the life of the light source using the LED.

Therefore, the cost and time required for the maintenance of the LED street light is suppressed, thereby spreading the installation of the LED street light, which is useful in all respects, thereby reducing power consumption and contributing to protecting the environment.

In addition, since the ventilation holes are narrow and deep in shape, they prevent rainwater from entering during rainy weather and prevent the inflow of foreign substances such as dust and insects (today), so it is possible to maintain roughness even if the inside of the luminaire is not cleaned from time to time. It also has the effect of reducing maintenance costs.

Looking at a preferred embodiment of the present invention based on the accompanying drawings as follows.

1 is a front view of the luminaire of the LED street lamp according to the present invention, Figure 2 is a sectional view of the luminaire according to the present invention, Figure 3 is a perspective view of the vent according to the present invention, Figure 4 is a bottom perspective view of the vent according to the present invention, Figure 5 Is AA sectional drawing of FIG.

According to the present invention, in the street lamp in which the light source 10 using the LED is installed in the lamp 1, the light emitting window of the lamp 1 is communicated with the internal space 5 of the lamp 1 in which the light source 10 is installed. 2) Drill the installation hole 4 in which the rainwater inflow prevention jaw 40 is formed in the bottom of the main body 3 of both sides, and install the ventilation hole 20 here.

The vent 20 is configured in the form of a container having a side portion 21 and the blocking portion 22, the fine protrusion 23 is repeatedly formed on the outer periphery of the side portion 21 of the main body 3 of the luminaire 1 The rainwater inflow prevention jaw 40 on the bottom was forced to be coupled to the installation hole (4) formed, a plurality of vent holes (24) passing through the blocking portion 22 straight from the end of the side portion 21 to the blocking portion (22) ) Was deeply formed.

The width of the ventilation hole 24 to be as narrow as possible will be effective to prevent the ingress of foreign matter or dust, the thickness of the blocking portion 22 thicker than the side portion 21 so that the depth of the ventilation hole 24 than the width Forming deeply because the surface tension of the water works well can be more effectively prevent the inflow of water through the ventilation hole (24).

In inserting the vent 20 into the installation hole 4, the vent hole 24 formed at the end of the side portion 21 is inserted to be exposed. Dig into the inner surface of the to allow the coupling.

In addition, the rear plate 6 of the luminaire 1 has several mounting stands 7 formed in the longitudinal direction of the luminaire 1, and then the LED board 30 is installed by using the mounting stands 7 so that the air is led through the LED board ( 30 is provided with an air passage (31) that can pass through.

Reference numeral 6 in the drawings is a street lamp post.

It looks at the operation of the present invention having such a configuration.

According to the LED street light of the present invention, the ventilator 20 is installed on the bottom surface of the main body 3 on both sides of the light emitting window 2 so that the internal and external air is basically distributed to have a heat generation function. When the air in the internal space 5 is heated and heated by the light source 10 using the LED, the internal air is discharged or the temperature decreases, thereby acting as a passage through which external air flows.

In general, the luminaire of the street lamp is generally installed inclined rather than horizontally.

Therefore, according to the present invention, since two vent holes 20 are installed at both sides of the main body 3 constituting the luminaire 1, the heated air is discharged through the vent hole 20 located at an upper side thereof, It is a natural circulation through which the outside air is introduced through the vent 20 is located.

Through this action it is possible to discharge the heat by the light source 10 using the LED inside the luminaire.

In addition, according to the present invention, since the air passage 31 is formed by the mounting table 7 installed in the longitudinal direction on the rear surface of the LED substrate 30, the air moves through the air passage 31.

The heat generated from the light source 10 using the LED is dissipated toward the LED substrate 30 and the heat generated from the LED substrate 30 itself can be cooled very effectively.

In particular, since the vent hole 24 of the vent hole 20 is narrow in width and is deeply formed in a straight line, it prevents the inflow of rainwater during rainy weather while maximizing the amount of air flow, and also prevents the inflow of foreign substances or insects. You can do it.

Moreover, since it is comprised so that it may be forced to the installation hole 4 by the external protrusion 23, it is convenient to assemble and it can prevent that it isolate | separates even in a shock or shake.
