Fluorescent lamps are difficult to manufacture because of the vacuum glass tube (mercury discharge tube) should be sealed sufficiently, and the user has to feel the fatigue of the eyes due to the problem that the intuition light is blinking for a long period of time. And is not turned on at a voltage lower than the reference value. In addition, it takes a long time to light up to emit light, and there is a disadvantage that the fluorescent lamp is broken when overheated.

Therefore, in recent years, there have been proposed methods for solving these problems, such as the efficiency of converting power into light, the efficiency of light to unit power is high, the lifetime is semi-permanent, and the electric energy is directly converted into light energy, (LED) that can obtain high efficiency and low illuminance are developed and are widely used for various purposes.

In the case of the straight tube type LED lamp, the light is dimmed from the surface on which the PCB of the LED where the LED is disposed. This is compared with the case where the light is dimmed from the whole area in the case of a fluorescent lamp.

In such a fluorescent lamp type LED lamp, the dimming has a direction and the angle at which the light spreads is limited. This can result in blind spots where the light can not reach.

As a solution to this problem, it would be desirable if the body could be rotated in an intuitive LED lamp.

As an art capable of changing the irradiation direction of the LED lamp, an intuitive LED lamp is disclosed in Korean Utility Model Publication No. 20-2011-0012044.

The technique comprises: an LED substrate comprising one or more LEDs; A wired heat sink is formed on the outer surface in the longitudinal direction and the LED substrate is fitted and fixed to the substrate inserting portion formed by the latching protrusions formed along both side edges of the upper surface and the wire connecting holes are perforated near both ends of the upper surface Semi-cylindrical base; And a pair of side caps which are covered at both ends of the semicylindrical base and are electrically connected to the LED substrate at an end of a terminal inserting opening formed at the front side and are made transparent so that light of the LED is transmitted therethrough do.

However, in the above-described technology, the adjacent LED lamp connected to the LED lamp is coupled to the connection terminal, wherein the connection terminal includes a body having a predetermined thickness and a pair of electrode pins protruding from both sides with respect to the body Accordingly, there is a drawback that a discontinuous section in which no LED is provided between the LED lamps is generated.
