Description

Image lighting fixture

This creation is about a luminaire, especially about image lighting fixtures.

Most of the lighting fixtures are suspended on the roof or ceiling. Because traditional light sources are mostly fluorescent lamps, energy-saving bulbs or projection lamps, LED lamps have been used more and more in recent years, but printed or painted on the lamps. It is rarely seen. Of course, because the uniformity of the lighting surface is insufficient, it is difficult to express the image effect. The decorative painting on the lamp surface will obviously reduce the lighting effect of the lamp.

Many of the signs and signs are mostly based on the use of fluorescent lamps, so that the light is exposed from the mark, but other parts of the light source are wasted. Under the current energy-saving claim, some of the signs are also LED-embedded, but they are too glaring. However, the effect of the label is lost, so the light guide plate panel light arranged in the form of a graph will be the direction of energy saving in the future.

In view of the above problems, the object of the present invention is to provide an image illumination lamp which utilizes the density or size of the distribution of the light guiding points of the light guide plate to evenly distribute the light of the light source, thereby generating the effect of planar uniform light. The light guiding point is the principle that the amount of light emitted during evacuation is small, and the amount of light emitted when the light is large is large, and the arrangement of the light guiding points is redesigned to exhibit different brightness effects in different regions, and the whole method is designed to be used in this way. Only the image portion of the illumination surface has a large amount of light emitted, while the other portions emit only a small amount of light, so that the electric energy consumed outside the image can be reduced under the same amount of light emitted from the image portion.

The aspect of the present invention provides an image lighting fixture comprising: a lighting fixture for emitting light; and an image sticker adhered to the surface of the lighting fixture, having a light transmitting portion and a non-forming image area The light-shielding portion of the image region is formed; wherein the light fixture comprises a light guide plate, and the plurality of light guide points in the light guide plate are concentratedly distributed in an area of the light guide plate in a region corresponding to the light-transmitting portion of the image sticker.

In order to make the present invention more familiar to those skilled in the art to which the present invention pertains, a number of preferred embodiments of the present invention are listed below, and the composition of the present invention and the desired content are described in detail in conjunction with the drawings. The effect.

1 is a schematic cross-sectional view of an image lighting fixture of the present invention, FIG. 2A is a schematic diagram of an image sticker of the image lighting fixture of the present invention, and FIG. 2B is a distribution of light guiding points of the light guiding panel of the image lighting fixture of the present invention. Schematic diagram, FIG. 3 is a schematic diagram of the light output of the image lighting fixture of the present invention.

In FIG. 1, FIG. 2A and FIG. 2B, an image lighting fixture 10 includes a photo. The light fixture 12 and an image sticker 14 are provided. The luminaire 12 is used to emit light. The image sticker 14 is adhered to the surface of the illumination lamp 12, and has a light-shielding portion 16 that forms an image (ie, an arrow image of 2A) and a light-shielding portion that forms an image region (ie, an area other than the arrow image of FIG. 2A). Part 18.

The image sticker 14 has a first light reflecting layer 30, an intermediate layer 32 and a second light reflecting layer 34. The intermediate layer 32 having an adhesive property adheres the first light reflecting layer 30 and the second light reflecting layer 34 together, and the second reflective layer The layer 34 is adhered to the surface of the light guide plate 20 of the lighting fixture 12. The first light reflecting layer 30 is for reflecting the light that is incident on the image lighting fixture 10, and the second light reflecting layer 34 is for reflecting the light that is incident on the light shielding portion 18 of the image sticker 14.

The lighting fixture 12 includes a light guide plate 20 and a light source 22. The material of the light guide plate 20 is acrylic, and the light source 22 is a light emitting diode or a cold cathode tube. A plurality of light guiding points 24 in the light guide plate 20 are concentratedly distributed in a region in the light guide plate 20 of the region of the light transmitting portion 16 of the corresponding image sticker 12 (that is, a region of the gray-scale arrow pattern of FIG. 2B).

As shown in FIG. 3, the light source 22 emits light to be incident on the light guide plate 20, and the light incident on the light guide plate 20 is concentrated by the light guide point 24 in the region of the light transmitting portion 16 of the corresponding image sticker 14 (ie, 2A). The area of the arrow image emits light, and only part of the light is continuously reflected in the light guide plate 20.

The distribution of the light guiding points 24 is mainly to make the light incident on the light guide plate 20 have a strong and weak distribution. If the density or aperture of the light guiding point 24 in the region of the light transmitting portion 16 of the corresponding image sticker 14 is increased, the corresponding map is reduced. The density or aperture of the light guiding spot 24 in the area of the light shielding portion 18 of the sticker 14 is reduced, so that the amount of light emitted by the image portion of the image sticker 14 is increased, and the amount of light emitted by other portions is reduced, and the brightness of the image portion can be increased. Use lower power under constant conditions to save power.

This creation provides an image lighting fixture that is characterized by the use of light guides The distribution of the light guiding points of the plate is evenly distributed to uniformly distribute the light from the light source, thereby producing the effect of planar uniform light. The light guiding point is small when the light is scattered, and the light output is large when the light is dense. The principle is to redesign the arrangement of the light guiding points to show the different brightness effects of different regions. In this way, only the image portion of the entire illumination surface has a large amount of light emission, while other parts only emit a small amount of light, so It is possible to reduce the power consumed outside the image with the same amount of light emitted from the image portion.

Although the present invention has been described above with reference to preferred embodiments and exemplary drawings, it should not be considered as limiting. A person skilled in the art will be able to make various modifications, omissions and changes to the form and specific examples thereof without departing from the scope of the claimed invention.
