Description

Signage lighting system using LED module and reflector

The present invention relates to a signboard lighting system using an LED module and a reflector, wherein the LED module assembly coupled to the LED module assembly in both directions obliquely between the reflectors provided inside the signboard frame is coupled in the horizontal direction.

In general, the signboards that have been used up to now are mainly composed of fluorescent light signboards and neon signs that light up when necessary by incorporating fluorescent lights inside the opaque acrylic signs, and light emitting device signs and optical fiber signs are also partially used.

In the case of fluorescent lighting signs, fluorescent lamps and ballasts are built-in, which not only has a considerable thickness but also has a problem that the fluorescent lamp bulb has a short durability and needs to be replaced frequently.

In the case of neon sign signboards, high-quality lighting effects such as subtle lighting effects can be expected, but because they cannot display sophisticated figures, they appear not only in the coarse form in the small sized signs in the short distance, but also due to excessive installation cost and power consumption. It is giving a lot of burden to.

Signage using a light-emitting diode (LED) has the advantages of long durability, low installation cost and low power consumption. However, since the light emitting elements emit light to the display surface of the signboard and illuminate the light vertically, there is a contrast difference between the portions where the light emitting elements are and the portions that are not, and the quality of the lighting is expressed by neon signs or fluorescent lamps. There is a problem that cannot expect high quality lighting effects such as soft lighting effects.

In addition, since the light emitting devices are installed perpendicular to the display surface of the lighting sign board to illuminate the display surface, there is a problem that a large amount of light emitting devices corresponding to the area of the display surface is required.

The present invention is to minimize the installation cost and power consumption to reduce the burden on the consumer while preventing the difference in contrast (dark phenomena) generated on the display surface of the signboard, high quality such as soft lighting effect The lighting effect can be obtained, and the heat generated from the LED can be easily released.
