Description

Save electricity type LED lighting device

The present invention relates to an ultra-low power LED lighting device, and more particularly, it is possible to reduce the electric energy by lighting using a power consumption of 0.1 ~ 0.5W class LED, and also to emit light from the LED The present invention relates to an ultra-low power type LED lighting device that enables to illuminate a billboard or a room brightly by indirect lighting that reflects and diffuses light emitted from each of a plurality of LEDs by indirect lighting that reflects and illuminates light.

In general, fluorescent lamps have been widely used to illuminate outdoor billboards and indoors, and in recent years, LEDs that emit light brightly at low voltage instead of lighting devices using incandescent lamps or fluorescent lamps to save electrical energy due to high oil prices. The trend is to change or to change the lighting device to the light source.

The LED has the advantage of emitting light brightly even at a low voltage, while having the characteristic of illuminating the light emitted in one direction, such as a flashlight, without being illuminated in all directions.

When the LED light is directly illuminated, the light emitted from the LED illuminates in a straight direction, such as a flashlight. Therefore, in the case of a billboard, the light emitted from the LED appears as a point light source. There is a problem that can not be brightly illuminated with brightness, and also when the room is directly illuminated with the light of the LED is a problem that the glare occurs.

Therefore, in order to solve the above problems, there has been proposed an LED lighting device that illuminates the light emitted from the LED by reflecting the light reflecting toward the reflecting surface of the reflector, which is fixed to the support fixed to protrude to the inner center of the reflector. Since the number of installed LEDs is limited, LED lighting devices are manufactured using LEDs that can be illuminated with strong lights, that is, SMD LEDs or power LEDs.

However, since the SMD LED is more than ten times more expensive than the conventional 0.2-0.5W class LED and high voltage of 3W or more is used, the LED lighting device using the SMD LED as a light source has a lower voltage than that of the LED. It is pointed out as a problem that the production cost is much more expensive and the power consumption is higher than that of the light source, and that the power LED is also expensive and uses a high voltage.

The present invention has been proposed in view of the above-mentioned problems appearing in the prior art, and can be supplied at a low production cost by using LEDs having a power consumption of 0.1 to 0.5 W, and can brighten electric energy. The present invention has been invented for the purpose of providing an LED lighting device for illuminating.

The present invention as a means for achieving the above object,

In the LED lighting device consisting of a reflector shade formed with an inclined reflecting surface on the inner surface, and an LED module fixedly attached to the inner center of the reflector,

The LED module,

A plurality of LEDs are arranged concentrically on the surface of the printed circuit board fixedly attached to the inner center of the reflection shade to illuminate the light emitting toward the open front of the reflection shade, and the light emitting from each of the plurality of LEDs Conical to be installed so that one end with a smaller diameter is positioned at the center of each of the LEDs arranged in a concentric manner so as to deflect and reflect the light toward the inclined reflecting surface of the reflector. Characterized in that it further comprises a reflective member.

In addition, one end of the small diameter of the conical reflecting member is fixedly attached to the printed circuit board at the center of the plurality of lamp-shaped LEDs are arranged in a concentric circle, the other end formed with a large diameter of the light emitted from the plurality of LEDs It is characterized in that it is formed of a diameter larger than the diameter of the concentric circle formed by the plurality of LEDs in order to be illuminated in front through the inclined reflecting surface of the reflection shade instead of being directly illuminated to the front of the reflection shade.

According to the present invention, the light emitted from each of the plurality of LEDs arranged concentrically on the printed circuit board of the LED module is not directly illuminated by the open front of the reflector. The light emitted from each of the plurality of LEDs is broadly refracted and diffused in a state of being diffused by forward reflection by the reflective surface inclined again after being refracted and reflected, in particular, the LED module is 0.1 to Since 0.5W class LED is used as a light source, even if a plurality of LEDs are used to construct an LED module, the production cost is lower and electric energy can be saved as compared with the conventional LED lighting apparatus using expensive SMD LED as a light source. There is an advantage to provide an ultra-low power LED lighting device, and also the LED lighting device of the present invention outdoors When applied to a high-rise device, the point billboard does not appear on the front billboard, and the entire billboard can be clearly illuminated with the same brightness.When applied to a ceiling lamp, it is possible to illuminate the interior while preventing glare.
