Description

SAFETY LED LIGHTING FITTING FROM SHORT CIRCUIT}

The present invention relates to a bulb-type LED lighting fixture, in particular, because the PCB of the driving unit is contained in the insulating member, the insulation is secured without securing a large insulation gap, thereby reducing the housing size and improving the performance and quality characteristics of the product. The present invention relates to a safety insulated bulb type LED luminaire that can be easily assembled and assembled to significantly improve productivity.

LED (Light Emitting Diode) is smaller and longer lifespan than the conventional light source, and because the electric energy is directly converted to light energy, it consumes less power and has a characteristic of emitting high brightness with excellent energy efficiency.

Accordingly, various lighting apparatuses using such LEDs as light sources have been developed, and in recent years, bulb-type LED lighting apparatuses equipped with bulb-type power connection parts to be mounted on existing light bulb sockets (Receptacle) have gained popularity.

The driving unit 120 should be installed so that insulation is securely made with respect to the housing 150. In the CE Marking system, the driving unit 120 exposes the driving unit to prevent a short circuit caused by moisture. And a safety insulating gap S of 6.5 mm or more may be forced between the housing 150 and the housing 150.

When configured to meet such a regulation, even if the size of the drive unit 120 is minimized, the size of the housing 150 is large and is incompatible with the conventional halogen lamps.

In addition, since the housing 150 is increased, the amount of heat generated from the light source unit 110 does not directly fall to the outside, and the heat rising from the center of the light source unit 110 is directed to the PCB 123 of the driving unit. There was a problem that caused the deterioration of quality and shortened life.

Meanwhile, in another prior art 100 ′ for solving such an insulation problem, the molding unit M may be embedded in the driving unit 120 as one bundle as illustrated in FIG. 7.

The insulating member 70 in which the 23 is contained is provided.

Here, the insulating member 70 is preferably formed in the shape of a container surrounding the outer periphery from the lower portion of the driving part PC (23).

Preferably, the insulating member 70 has a PCB seating end 73 formed at a position spaced apart from the bottom surface 71. This configuration is for accommodating the portion protruding downward of the driving part PCB (23).

In addition, the insulating member 70 has one or more cable passages 75 connected from the driving unit 20 to the light source unit 10.
