Decorative LED lighting device {Decorative LED lighting device}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a decorative LED lighting device in which light is radially dispersed to obtain an interior effect. More specifically, the present invention relates to a reflective LED lighting device having a reflective member such as a cubic reflector having a plurality of inclined surfaces formed on at least one of an upper surface and a lower surface And a light emitting member such as an LED chip that emits light to the inside of the lower portion is scattered and refracted through the inclined surface of the reflecting member so as to be dispersed in a radial manner to provide a decorative LED lighting device .

In general, a lighting device is a device that fixes or protects a light source that reflects, refracts, or transmits light of a light source, converts electric energy into light energy by receiving power, .

Light sources such as incandescent lamps, fluorescent lamps, light emitting diodes (LEDs) and the like are used as the light sources of the above-mentioned lighting apparatuses. The light emitting diodes, that is, the LED chips, are formed by using the pn junction structure of semiconductors to make injected minority carriers, Refers to a device that emits a predetermined light, and includes a red LED using GaAsP or the like, and a blue LED using a green LED InGan / AlGaN double hetero structure using GaP or the like.

In particular, since LED converts electric energy directly into light energy, it has a high conversion efficiency to light energy compared to incandescent lamp, fluorescent lamp, and halogen lamp and does not generate heat during light emission.

Such LEDs are used as display devices and backlights, and active research is currently underway to apply them to general lighting applications. In particular, a combination of light emitted from a single color component, for example, red, Of course, besides being able to emit light close to natural colors, white LED devices are expected to increase rapidly in application to automobile and lighting products, and are expected to have a small size, a long life span and a high efficiency The development is promoted as eco-energy.

Meanwhile, when such an LED is used in a lighting apparatus for an ornamental or an interior, the LED may be simply attached to the body of the ornament or the lighting apparatus, or protruded or mounted on the upper case while supplying power to the LED as an independent element The present invention has been developed in order to solve the above-mentioned problems. For example, Korean Patent No. 1179288, Korean Patent Publication No. 2000-0071959, Korean Utility Model Application No. 1999-0033486 etc. .

However, in the above-mentioned conventional techniques, the light emitted from the LED is dispersed through the inclined surface in the jewel or artificial jewelry to obtain the effect of improving the personality of the ornaments or enhancing the interior. However, It is difficult to actually apply such an LED chip to a decorative interior because the LED chip itself is formed with a reflective material (cubic) integrally in addition to being monotonous in terms of color rendering, and artificial jewel having an inclined surface due to heat generated from the LED There was a problem of deformation or fire.

In addition, the above-described conventional techniques have a problem in that the LEDs are protruded outward to supply power to the LEDs, thereby reducing the interior effect and frequently replacing the batteries when the batteries are used to prevent the LEDs from protruding.
