Description

[0001] The present invention relates to a Bulb-type LED lamp having a heat-

The present invention relates to a bulb type LED having a heat dissipation path for improving durability through an improved heat dissipation structure.

In general, a lighting device that can generate a luminance similar to a conventional incandescent lamp and a fluorescent lamp with low power is a light emitting diode (LED) lighting device. A light emitting diode (LED) (Electrons or holes) are injected into a semiconductor device which emits light by using a pn junction structure of m semiconductors, and light is emitted by recombination of these carriers.

Since LED has high efficiency to convert electric energy into light energy, LED can save energy by up to 90%, and it is attracting attention as next generation light source that can replace incandescent lamp and fluorescent lamp which is only about 5% of energy efficiency. , It has a very compact size, has a semi-permanent life span, low power consumption, high energy efficiency, and does not contain harmful substances such as mercury and lead, thus being environmentally friendly.

When an electric current passes through the conductive material attached to the lower electrode, the electric charge and charge particles, called electrons and electrons, are combined at the center of the electrode to emit a photon of light. According to the characteristics of the material, It is different.

Lighting devices using these LEDs are used in a variety of fields such as home lighting, office lighting, factory lighting, street lighting, earlobe, landscape lighting, and lighting for leisure facilities.

However, there is a problem that the LED generates high heat when emitting light, and the lifetime is shortened due to such a high temperature.

Accordingly, although heat dissipation fins for heat dissipation are provided inside the lighting apparatus using conventional LEDs, it is difficult to expect effective heat dissipation by using only the heat dissipation fins, resulting in a reduction in heat dissipation efficiency, thereby deteriorating the durability of the lighting apparatus.
