Description

Blind apparatus capable of LED indirect illumination

The present invention relates to a blind device capable of LED indirect illumination.

In general, blinds are used for the purpose of blocking light or protecting privacy. Such blinds are installed in offices, living rooms, bedrooms, study rooms, student rooms, kitchens, children's rooms, windows, and verandas to allow some ventilation and block sunlight to fade indoor furniture, appliances, and carpets. It has a function to block the outside, to some extent, and to decorate the atmosphere of the room.

Such blinds include roll blinds, vertical blinds, horizontal blinds, and shades. Roll blinds are constructed so that the flat fabric itself winds up and stops at a constant height. Vertical blinds are configured so that the wings are lowered vertically so that the wings move from side to side and only on one side, and the wings move up to 180 degrees to control the passage of light. Unlike the vertical blinds, the horizontal blinds are configured so that the wings are lowered horizontally so that the wings are moved up and down. Such roll blinds, vertical blinds, and horizontal blinds use wings of various materials (slats, louvers), and are generally made of materials such as aluminum and polyester in order to prevent dust. On the other hand, the shade is also called the Roman shade, which is composed of a piece of fabric formed of a material such as natural materials as a wing, unlike the roll blind is configured to pull up the string installed inside the fabric so that the fabric is stepped up.

On the other hand, the brightness of the room can be adjusted by the amount of sunlight passing through the above-mentioned blinds during the day, and at night, the blinds are usually lowered and controlled by indoor lighting. In general, buildings in Korea provide a uniform structure and lighting devices, and in particular, since lighting devices are installed on the ceilings so that the lighting devices are direct lights instead of indirect lighting, there is no shadow or glare that is characteristic of indirect lighting. There was a problem in that the illuminance distribution was not uniform to produce a calm atmosphere.

In addition, indirect lighting, which is often used as architectural lighting for installing lighting fixtures on a ceiling or inside a ceiling, has a problem in that installation cost and time are not easy and easy to repair.

In addition, there is no blind device that implements IoT functions linked with ICT in the fourth industrial revolution.
