Description

Spherical luminaire using LED {LIGHTING DEVICE USING LED}

According to the present invention, the lamp can be more easily accommodated in the inside of the cover by passing through the small lamp opening formed in the upper portion of the spherical cover by the user, and the user can easily receive the lamp inside the cover. The present invention relates to a spherical luminaire using an LED that may be easily drawn out of the cover by.

Fluorescent lamps are the most commonly used light sources around us, and they are the most familiar light source. These fluorescent lamps are composed of separate parts such as fluorescent lamps and ballasts.

Fluorescent lamp is a tube sealed with argon gas and mercury vapor in it by applying fluorescent material, and when electricity is supplied, the lighting tube (bimetal) gets heated up with heat. Since it increases and destroys the electrode, a ballast such as a choke coil is used to limit the current to a certain value or less.

Most commonly used luminaires use fluorescent lamps as described above, and the conventional fluorescent lamps are driven using a frequency of 60 Hz. Therefore, the fluorescent lights are flickered 60 times per second. It feels a lot of fatigue, it causes a high power loss by increasing the ambient temperature due to the heat generated by itself for a long time, there is a disadvantage that the fluorescent lamp is easily broken when overheated.

As a result, conventional lighting fixtures such as fluorescent lamps have a problem in that the service life is shortened due to the temperature rise and the high power loss, and the replacement parts are expensive due to the large number of parts used.

In addition, in recent years, a compact lamp having a length of 1/2 to 1/3 compared to a general fluorescent lamp is used. The compact fluorescent lamp has the same brightness as the fluorescent lamp but reduces power consumption. Excellent reproduction characteristics.

Unlike compact fluorescent lamps, fluorescent lamps are formed only on one side of the socket. Therefore, the compact fluorescent lamp should be molded in consideration of the fixing force and the fastening force with the main body after installation of the compact fluorescent lamp.

On the other hand, LED (Lighting Emitting Diode), which is used as a replacement for fluorescent lamps or fluorescent lamps having the above characteristics, has an excellent efficiency of converting power into light, and is compared with incandescent lamps, fluorescent lamps, and compact fluorescent lamps, which are currently used. As the efficiency of light is much higher than unit power, it is excellent in economical efficiency, and high efficiency of illumination can be obtained even at low voltage, glare does not occur, and stability is excellent.

Recently, a spherical luminaire has been proposed to use a street lamp cover that is waterproof and beautiful in appearance.
