Methods and apparatus for substantially reducing dark spots on a front surface of a channel letter, including: forming a channel letter using a profile with at least one rib, the profile having a top and a bottom; coupling a face plate to the at least one rib; and filling a space between the face plate and the top of the profile with a resin material.

The illuminated sign includes a frame defining a space, a light emitting module received in the space and having a plurality of light emitting members disposed on a circuit substrate, an optical path conversion component provided on the frame to correspond to the light emitting members, and a light uniformizing component positioned a distance above the optical path conversion component. The space is compartmented to form a predetermined pattern, projecting a desired signal when the light emitting members in different compartments of the space are selectively illuminated.

A light emitting diode (LED) lens for a backlight unit for uniformly distributing light emitted from an LED chip that emits light via a volume source. The LED lens for a backlight unit includes a lower surface including an incident surface through which light emitted from the LED chip is incident upon the LED lens, an emissive surface from which the light incident upon the LED lens is emitted, and a total-reflection surface included in the lower surface so as to total-reflect the light emitted from the LED chip and incident upon the LED lens toward the emissive surface, wherein the total-reflection surface includes a first total-reflection surface convex downward and a second total-reflection surface connected to the first total-reflection surface and convex upward, and an inflection point is formed between the first total-reflection surface and the second total-reflection surface.

Provided is a side light-emitting type display device having a frame member. The side light-emitting display device having a frame member includes a display assembly configured to guide light to a side surface of the display assembly while displaying an image using light emitted from light sources; a transparent frame member which is configured to surround and fix the display assembly and through which the light guided to the side surface of the display assembly is transmitted; and a side display member provided on a side surface of the transparent frame member, and configured to display information of the image using the light guided to the side surface of the display assembly.

An indication device includes an indication portion made of a light transmitting material and a cover portion made of a light blocking material. The indication portion has a sign including at least one of a character, a symbol and a figure. The cover portion covers a periphery of the sign of the indication portion. The sign is illuminated by light emitted by a light source and guided to the indication portion. The cover portion is configured such that a recess from a surface of the cover portion is provided in a region corresponding to the sign of the indication portion.

The invention discloses an optical assembly comprising a plurality of optical components that are concentric to one another, each optical component having a partially reflective and partially transmissive interface with an oblique angle of incidence, and the reflectivity of the interface increasing with distance from a common center; a transitional optical component is provided between the light source and the first optical component in order to direct lights from a light source to the partially reflective and partially transmissive interface of the first optical component. By assembling the plurality of optical components, a much thinner lighting device (100) can be achieved.

Disclosed is a light diffusing panel, a light diffusing module and a traffic sign incorporating the light diffusing module. A front face of the panel has a plurality of linear disruptions, which disruptions redirect the light to emit from the front face of the panel in a broad diffuse emission. The plurality of linear disruptions extends as a series of parallel lines across the front face. A second plurality of linear disruptions extends as a series of parallel lines across the front face, with the first plurality of linear disruptions forming a grid across the front face. The light diffusing module adds to the light diffusing panel, a reflective sheet adjacent to the rear face of the light diffusing panel and light sources along an edge of the light diffusing panel. The traffic sign adds a message panel to the light diffusing module as well as a power supply.
