Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat radiation structure of a lighting device,

The present invention relates to a heat dissipating structure of a lighting apparatus to which a speaker is coupled, and more particularly, to a lighting apparatus having a speaker in a case of a lighting apparatus, The sound generated or emitted from the illumination unit or the heat dissipation unit provided in the illumination device through the communication unit, which is a separate path, by using the sound (vibration) generated from the speaker, To the outside of the case and at the same time to output sound in which the phase is inverted by 180 ° with respect to the sound directly output from the speaker.

2. Description of the Related Art Generally, an illumination device is a device for illuminating a specific place with various purposes by using various light sources, and is often used to brighten the surrounding environment or a target area at night or in a dark place.

However, in recent years, illumination using a light-emitting diode (LED) having an advantage of being efficient and having a long lifetime has been used as a lighting using the principle of semiconductor. In recent years, Is getting popular. The LED-based illumination operates on the principle of electroluminescence, in which the emission of the photons is caused by a phenomenon that is caused by electrically stimulating a substance.

These LED lights are smaller, more durable and longer in life than bulbs or fluorescent lamps. The size can be as small as dust, so it is possible to enter the thin cell phone early, and it is comparatively durable compared to the incandescent lamp which burns filament easily or the small plastic lump compared with the fluorescent lamp that glass is broken. And when used in an appropriate environment, it boasts a life span close to 1,000 times (hundreds of thousands of hours) compared to incandescent bulbs (hundreds of hours) and fluorescent lamps (thousands of hours).

However, there is a disadvantage in the LED lighting with the above advantages as well, which is relatively weak in terms of structure. The LED is fatal even in the temperature of fluorescent lamps that have been on for a long time, not to mention incandescent lamps that rise to several hundred degrees Celsius. It is because of the heat dissipation of the LED lighting that is vulnerable to heat as described above, because a bulky and heavy heat sink is attached to a commercially available LED bulb substituting an incandescent bulb. For reference, the lifetime of an LED light at an appropriate temperature is hundreds of thousands of hours, but the lifetime is reduced to one-half of the life as the temperature rises. For example, if the temperature exceeds 100 占 폚, there is a problem in that the time is several thousand hours.

More specifically, the one-dimensional heat conduction unit 131 has a pair of N-type and P-type semiconductor elements as a basic unit. When the DC voltage is applied to both ends, the N-type According to the flow of electrons, in the P type, the heat moves according to the flow of the holes and the temperature of the heat absorbing part is lowered.

This is because there is a difference in potential energy between the metal and the electron. In order to move electrons from a metal having a low potential energy to a metal having a high state, energy is taken from the outside, so that heat energy is taken away from the contact. Heat energy is released. This endothermic (cooling) is proportional to the current flow and the number of thermoelectric couple (N, P type pairs).

Strictly speaking, according to the vibration of the speaker 140, the outside air is drawn into the case 110 through the communication part 150, and the heat inside the case 110 is repeatedly discharged to the outside.

For reference, the above-mentioned sound pressure is generated by a portion where air is displaced when sound waves are present and the pressure is higher than the atmospheric pressure, and a portion where the air is displaced to become thinner and the pressure is lower than atmospheric pressure is generated, The change in pressure occurs at this atmospheric pressure.
