Description

  The present invention relates to a streetlight structure, and more particularly to an LED streetlight heat dissipation structure that uses an LED as a light source and can increase the heat dissipation effect.

  A streetlight that illuminates the darkness is an extremely important facility in terms of safety. In consideration of ecology and energy saving, many manufacturers are researching and developing alternatives to street lamps, mainly incandescent bulbs, halogen lamps, fluorescent lamps, mercury lamps and sodium lamps. Compared with other light sources, light-emitting diodes have a feature that can significantly save energy, and are widely used in various lighting devices, and in particular, street lights that illuminate roads.

  Light-emitting diodes (LEDs) are cold-emitting, and have characteristics such as low consumption of electricity, long life of components, low pollution, no warm-up time, fast reaction speed, and high efficiency. In addition, since street lights require brighter light illuminance, it is usually possible to obtain brighter light illuminance by adopting a highly efficient light-emitting diode and passing a relatively large amount of current through the light-emitting diode.

  However, it is inevitable that heat is generated at the same time as increasing the illuminance. If the generated heat is not immediately exhausted, heat is accumulated around the light emitting diodes, resulting in a decrease in luminous efficiency, and further affects the life of the light emitting diodes. However, although there are many street lamps that use LEDs as the main light source, there is always a current situation that the heat dissipation effect is poor. Therefore, the street lamps that use LEDs as the main light source are burned out due to high heat, the brightness decreases, and the life is shortened. In view of the shortcomings such as becoming, further improvement was necessary.

  In order to solve the drawbacks of the known structure, the present invention mainly aims to provide an LED streetlight heat dissipation structure that increases the heat dissipation effect.

  In order to solve the above-described object, the present invention provides a heat dissipation structure for an LED street light. A streetlight main body and at least one heat dissipating fan, which are integrated with the column, are provided, a cover is provided at one end of the streetlight main body, and an LED light emitting module is installed in the cover. A ventilation duct that penetrates the streetlight body is provided, and a heat dissipation fan is installed in the ventilation duct. The heat dissipating fan generates an air flow in the air duct and causes the air flow to flow to the LED light emitting module. Therefore, the heat dissipating effect of the entire LED light emitting module can be effectively increased.

  The present invention includes a ventilation duct penetrating the streetlight main body, and a heat radiating fan and a hole are installed in the ventilation duct so that air entering from the hole creates an air current by the heat radiating fan, and the air current is an LED light emitting module. Since the heat is exhausted from the vent together with the airflow, the heat radiation effect of the entire LED light emitting module is effectively increased, and the light intensity of the streetlight main body is increased together with the vent duct, and an energy saving effect is also obtained.

It is a three-dimensional exploded view of another best embodiment of the present invention. 4 is a schematic cross-sectional view of another preferred embodiment of the present invention. 2 is a schematic diagram of another best embodiment of the present invention.

  In order to clearly show the LED streetlight heat dissipation structure according to the present invention, a detailed description will be given with reference to the drawings, but this does not limit the protection scope of the present invention.

  FIG. 1, FIG. 2 and FIG. 3 show the best embodiment of the LED streetlight heat dissipation structure of the present invention. The LED streetlight heat dissipation structure of the present invention is composed of a streetlight main body 1, at least one heat dissipation fan 2, a cover 11, and a translucent cover 12. A cover 11 is provided at one end of the streetlight main body 1, and a translucent cover 12 capable of transmitting light is installed on one surface of the cover 11. An LED light emitting module 13 is provided in the cover 11, and a light source generated by the LED light emitting module 13 is irradiated through the light transmitting cover 12. The interior of the streetlight main body 1 constitutes a hollow through-duct ventilation duct 14 and is installed in the cover 11 at the opening of the ventilation duct 14. A hole 15 is provided in a part of the ventilation duct 14 close to the cover, and the radiating fan 2 is installed in the hole 15. The radiating fan 2 that is electrically connected sucks air from the hole 15 to generate an air current. It flows inside and flows to 11 openings. A vent 16 is further provided behind the translucent cover of the streetlight main body 1. The LED light emitting module 13 is energized to emit light, and the light is emitted through the ventilation cover and the light transmitting cover 12. At this time, the LED light emitting module 13 generates heat at the same time, and the heat is discharged from the vent 16 together with the air flow generated in the ventilation duct 14 by the heat radiating fan 2. Since the temperature around the LED light emitting module 13 can be effectively lowered by the air flow generated by the heat radiating fan 2 and the overall heat radiating effect of the LED light emitting module 13 can be increased, the street lamp body 1 increases the light illuminance. Both the ventilation ducts can also save energy.

  FIGS. 4, 5 and 6 show another embodiment of the present invention. Since the whole structure and the method of connecting the parts are roughly the same as in the first embodiment, they will not be mentioned again. The difference from the first embodiment is that the radiator 3 is installed on the LED light emitting module 13 and the heat sink heat conduit 4 is inserted into the radiator. The LED light emitting module 13 installed on the cover 11 is energized to emit light, and the light source is irradiated through the translucent cover 12. The heat generated by the LED light emitting module 13 is emitted to the outside through the radiator 3 and the heat conduit 4 and is discharged from the vent 16. The heat dissipating fan 2 sucks air from the holes 15 to generate an air flow, and the heat absorbed by the heat dissipator 3 flows quickly with the air flow and is discharged from the vent 16. Thereby, the heat radiation effect of the LED light emitting module 13 as a whole can be effectively increased, and the streetlight main body 1 can increase the illuminance of light and can also achieve an energy saving effect.

The heat dissipation case structure of the heat dissipation module of the present invention has the following merits:
1. Good heat dissipation effect.
2, good heat conduction effect 3, easy to disassemble and maintain 4, energy saving and light illuminance can be increased.

  The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Even if a person familiar with the present technology makes changes or adjustments within the scope of the present invention, the important significance of the present invention is not lost and is included in the scope of the present invention.
