Description

LED Lights with louvers

The present invention relates to an LED lighting lamp having a louver, and more particularly, to an LED lighting lamp having a louver that can block light emitted directly from the lamp to soften an indoor atmosphere and prevent glare.

In general, a lighting lamp is provided with a main body that forms an exterior so that one side is opened while being embedded in the ceiling, and both sides of the fluorescent lamp are fixed and a socket to which power is applied is coupled and fixed on both sides of the main body.

A louver for dispersing the light of the fluorescent lamp is coupled to one side of the open body to prevent glare of the user due to the light emitted from the fluorescent lamp.

Louver-type ceiling lights are installed in subways, underground plazas, or building lobbies.

In a conventional louvered ceiling lamp, a plurality of straight-pipe type fluorescent lamps are arranged in parallel in a hanger extending downward from the ceiling or in a case installed on a rail suspended from the hanger, and a louver is detachably provided in the open bottom opening of the case. structure will be taken.

In the conventional louvered ceiling lamp, the lamp is placed between the parabolic louver and the louver, so that the lamp is exposed through the louver. Although it is not incident with human eyes, if a person approaches under the louvered ceiling lamp, the light from the lamp is directly incident on the human eye despite the louver. There was a problem that the atmosphere could not be achieved.

Louvers are used in various ways depending on the purpose or effect of use, that is, they are formed in various ways, such as translucent glass materials and synthetic resin materials, or a grid shape in which the grid plates are intertwined in the horizontal and vertical directions.

On the other hand, since the conventional louver has a lattice shape, there is a problem in that a lattice-shaped shadow is generated when light is irradiated.
