The present invention relates to an LED lighting lamp, and more particularly, a standing type having a non-closed variable type bulb in which the height and width of the bulb are repeated gradually over time. Or it relates to an LED lighting lamp of the ceiling or side wall fixed type.

In the late 1990s, various and wide-ranging attempts were made to apply LEDs to lighting, achieving remarkable achievements, and the LED lighting market is expected to grow by more than 20% annually. Is expected to be more than $ 10 billion.

LED has high light conversion efficiency, so it consumes less power and has a large energy saving effect, but it is relatively easy to control the amount of light and luminous flux.The small light source is suitable for miniaturization and light weight, but has a long life of approximately 30,000 hours or more. It is widely used for high quality indoor and outdoor lighting because of its simple circuit, high impact resistance, low environmental pollution, less optic nerve fatigue, and full color. As the high-brightness LED that improves the low-brightness problem is commercially available on the market, its use and application are rapidly expanding.

In particular, since white LED is very useful for indoor and outdoor high-grade lighting, its frequency of use is rapidly increasing, and it is expected to dominate the lighting market by releasing the fluorescent light market in the same way as the trend of ousting the incandescent lamp by fluorescent light.

On the other hand, high power and high efficiency LED lighting lamps have a relatively large volume and weight compared to LEDs because of their inherent high heat generation characteristics resulting in deterioration of optical output characteristics and efficiency, shortening of life and deterioration of peripheral components and devices. There is a problem that a heat sink or a heat spreader must be employed.

Therefore, in the conventional bulb type LED lighting lamp, in order to improve heat dissipation, a heat sink or heat spreader was exposed to the outer surface of the bulb body, and the size or area of the bulb was increased.
