The present invention relates to a heat radiation wind generator inside the lighting device, and more particularly, to a micro heat radiation wind generator structure for effectively dissipating the heat generated internally using the principle of the electromagnet.

In general, an LED (light-emitting diode) is a light emitting device using a phenomenon that the light is generated when the current flows to the PN junction of the compound semiconductor, such as GaP, GaAs, etc., by adjusting the component ratio of the semiconductor compound in manufacturing the light emitting diode It can generate light of a desired wavelength.

These LEDs are used not only for medical use using a predetermined wavelength but also for promoting plant growth. In particular, LEDs have low power consumption and high visibility. Therefore, LEDs are recently used as traffic lights, vehicle rear lamps, and outdoor advertising signs. Also widely applied, the scope of application is gradually expanded to replace the known lighting means.

However, in the conventional lighting device, a separate heat dissipation fan is installed inside the device to prevent the internal temperature rise due to heat generated from the lamp. The heat dissipation fan driven by the motor driving method has a limited lifetime. Because of the limited use period there was a problem.

The present invention has been proposed to improve the problems caused by the use of the conventional heat dissipation fan, and improves the reliability of the device by configuring a heat dissipation wind generator having a permanent life inside the lighting device instead of the heat dissipation fan having a limited service life. The purpose is to make it possible.

According to an aspect of the present invention, there is provided a lighting apparatus having a heat radiation wind generator for discharging heat generated therein to an outside, the heat radiation wind generator comprising: an electromagnet for generating a magnetic force upon application of current; A permanent magnet configured at a distance spaced from the electromagnet; It is integrally coupled with the permanent magnet, and the flow plate to maintain a certain elasticity; A power supply unit supplying power to the electromagnet; And a control unit for controlling the power supplied from the power supply unit.

In addition, the relay is characterized in that the relay is provided with a relay driving unit so that the power on / off supplied to the electromagnet can be made periodically.

The present invention provides an effect of maximizing the heat dissipation life compared to the existing heat dissipation fan by providing a heat dissipation wind generator structure that can generate the internal wind by the action of the electromagnet and permanent magnet in the lighting device.

In particular, when applied to the two-stage elastic plate structure using the spring can maximize the heat dissipation effect.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the state in which the heat radiating wind generator of the present invention is mounted inside the lighting device 1, the power from the power supply unit 14 is periodically turned on / off by the relay 11 driving. As a result, the magnetic force between the electromagnet 10 and the permanent magnet 20 acts at a constant cycle, causing the flow plate 30 to oscillate up and down toward the electromagnet 10 side, thereby generating heat radiation wind.

That is, the magnetic field is periodically formed in the electromagnet 10 by the relay power transmitted from the relay 11, so that the magnetic force with the permanent magnet 20 is generated when the magnetic field is formed, the flow plate 30 Is instantaneously attached to the electromagnet 10, and when the magnetic field is released, the contact with the flow plate 30 is released, so that the flow plate 30 is raised, so that the up and down flow of the flow plate 30 is generated.

The radiating wind generated in this way is to be quickly released to the outside through the vent (2).

Therefore, it can be seen that adverse effects due to heat generated inside the lighting device 1 can be prevented.

Therefore, it can be seen that the discharge of the internal heat radiation wind can be more maximized.

In addition, by forming a nano-silver coating layer 33 on the top or bottom of the flow plate 30 to exhibit the insect repellent, sterilization, heat shielding effect as a thin film, to improve the heat dissipation function and invasion of pests through the vent (2) It was to be able to represent the insect repellent efficiency to prevent.

In addition, the flow plate 40 is preferably provided with a thin metal material having elasticity, so that fluidity due to magnetic force generation between the power coil 60 and the permanent magnet 50 may be maximized.

In addition, the conductive wire constituting the power coil 60 is electrically connected to the power supply unit 44 so that power can be supplied from the power supply unit 44, the relay 41 for turning on / off the applied power at a predetermined cycle, The relay drive part 42 for driving the relay 41 and the control part 43 for operation control are comprised, respectively.

(4) It is configured on the front surface to enable light emission.

Therefore, the heat radiation wind generator of the present invention is fixed to the support plate 6 inside the lighting device (1).

In the figure, reference numeral 5 denotes a front lens mounted to the front of the lighting device 1 to protect the LED 3.

The effect of the heat radiation operation of the LED lighting apparatus according to the second embodiment constituting such a structure will be described.

In the state in which the heat radiation wind generator of the present invention is mounted inside the lighting device 1, the power from the power supply unit 44 is periodically turned on / off by the driving of the relay 41. As a result, the flow plate 40 vibrates up and down by the action force between the magnetic field generated in the power supply coil 60 and the permanent magnet 50 to generate heat radiation wind.

That is, the magnetic field is periodically formed in the power supply coil 60 by the relay power transmitted from the relay 41, and thus, when the magnetic field is formed, the magnetic force with the permanent magnet 50 is generated, thereby the floating plate 40 Up and down flow of) is generated.
