Description

[0001] The present invention relates to an interior lighting for improving light diffusion of an LED,

The present invention relates to a technique for preventing indirect lighting of indoor lighting mounted on a ceiling of a room to prevent glare.

In particular, the present invention relates to a technique capable of reducing the maintenance effort and the unit cost when the reflectance for indirect lighting is deteriorated due to decoloration or the like.

Unlike conventional fluorescent lamps, LEDs are excellent in energy saving and durability.

Here, unlike a fluorescent lamp, an LED has a high luminance and a strong directivity to provide a bright light. However, since the dispersion of light is weak, arranging the LED to be directly exposed in an indoor lighting lamp presents problems such as a user's glare.

In order to overcome this, conventionally, when a LED lighting lamp is manufactured, a transparent panel covering an LED is essentially installed in an LED lighting lamp, thereby preventing a user's glare.

However, it is difficult to realize the inherent color of the LED according to the transparency or the material of the panel covering the LED, and the panel does not utilize the advantage of the luminescent light of the LED as it reduces the inherent brightness of the LED There was a problem.
