Description

[0001] LAMP ASSEMBLY HAVING ISOLATION BARRIER [0002]

The present invention relates to an LED lamp assembly, and more particularly, to an LED lamp assembly having an insulating barrier applicable to an FPL type socket.

BACKGROUND ART [0002] In recent years, LED devices have been spotlighted as light sources for various lighting devices. The LED element has advantages such as less heat generation, less power consumption, longer lifetime, and impact resistance than a conventional illumination light source. In addition, since mercury or a discharge gas is not used in the manufacturing process like a fluorescent lamp, there is an advantage that it does not cause environmental pollution.

If the LED device provides adequate power supply and heat dissipation means, it can maintain the lighting state without burning even if used for over 100,000 hours. All light sources decrease in light output as time passes. Since 80% of the initial brightness is not felt well by people, the life expectancy of LED devices is expected to be about 40,000 to 50,000 hours.

Therefore, compared to 1,500 hours of incandescent lamps and 10,000 hours of fluorescent lamps, LED devices have a long life span.

However, if the existing fluorescent socket is discarded in order to use the LED lamp, not only the resources are wasted but also the expensive socket is required to use the LED lamp.

In particular, the FPL (Fluorescent Parallel Lamp) type lamp is a "U" shaped lamp having a structure in which the conventional straight tube type lamp is folded into two, unlike the straight tube type lamp, It is also necessary to simply apply the LED lamp to the socket for the lamp of the lamp.

In addition, in order to obtain an economical light source for a high luminance and high output in an LED lamp, when the driving current applied to the LED device is increased, power loss is increased so that most of the electric energy is converted into heat and the junction portion of the LED device becomes high temperature. The heat may be transferred to a power supply control board (SMPS) disposed adjacent to the LED device, possibly causing malfunction of the power control board.
