Description

Anti-glare lighting and manufacturing method thereof

The present invention relates to an anti-glare lighting lamp and a method for manufacturing the same, and by blocking the light directly irradiated to the eyes to prevent the glare of the lighting lamp indoors, and refracting the light so that the entire amount is irradiated downward, the illuminance is significantly improved. It relates to an anti-glare lighting lamp capable of reducing eye fatigue and a manufacturing method thereof.

A fluorescent lamp consists of a glass tube filled with a mixed gas of argon and mercury vapor, and when an electric current flows between the ionized gas between the metal electrodes at both ends, it emits light and a significant amount of ultraviolet light is emitted. It is painted with a phosphor that emits light and a fluorescent material that re-emits ultraviolet energy as visible light.

Fluorescent light has a strong glare, and if you look straight at it for a long time, it has a significant effect on your eyesight, and even if a phosphor that absorbs ultraviolet light is painted inside the tube, some of the ultraviolet light tends to be transmitted as it is.

Therefore, when exposed to such ultraviolet rays for a long time, it is necessary to pay great attention to the pictures installed inside the building, the wallpaper and the painted parts, etc., as yellowing occurs.

When installing a fluorescent lamp fixture as a means to prevent glare, a louver plate equipped with a large number of louvers in a grid type is installed below the fluorescent lamp fixture. It prevents glare by preventing the internal fluorescent lamp from being directly visible.

On the other hand, conventional lighting lamps are inconvenient due to strong glare even when a shade is combined with a fluorescent lamp and a louver is used in the lower part. That is, there was a disadvantage that the glare was high.

In addition, since the louver is manufactured by injection molding, it is thick and expensive, so there is a limit to popular distribution.

Anti-glare lighting according to the present invention can reduce glare.

Glare refers to a state in which it is difficult to see an object due to light from a light source with high luminance or a reflective object in the field of view, or a state in which an object is uncomfortable due to glare.

There are three types of glare: Disability Glare, Discomfort Glare, Veiling Reflection, and Reflection Glare.

Glare is likely to occur within the field of view within 45° of the line of sight, and this range is called the glare zone.

Disability glare is glare that causes loss of visual function or reduces vision when an extremely bright light source, such as a headlight of a car, enters the field of vision.

Discomfort glare is glare that does not interfere with viewing an object, but causes discomfort due to a high-brightness light source in the field of view, deterioration of work efficiency, and eye fatigue.

Veiling Reflection and Reflection Glare are glare in which light from a high-brightness light source or window is reflected on the surface of the monitor, desk, or glossy paper and enters the field of view, making it difficult to see the object.

As a way to control glare, a translucent diffuser, prism panel, shader, or louver is used.

ISO and EN standards use the UGR suggested by CIE as a default value.

The value obtained by the UGR formula is called the glare index and is used as an index to evaluate unpleasant glare.

The UGR formula is:

In the disclosed invention, the glare zone is reduced to prevent discomfort.

Since the glare zone occurs within the field of view within 45 degrees of the line of sight, it was attempted to reduce it.

UGR grades are as follows [Table 1].

Rating degree 10 Imperceptible 16 Perceptible 19 Just Acceptable 22 Unacceptable 25 Just Uncomfortable 28 Uncomfortable 31 intolerable (just intolerable)

In general, 19 is appropriate for the UGR standard, and UGR=19 is indicated. For most offices, UGR 16-19 is appropriate.

The substrate 3 may include a PCB (not shown) on which a plurality of LEDs 32 are planted, and the LED may be emitted by power supply through an externally connected wire.

The diffuser 5 may be made of a synthetic resin material or a metal material, and the reflective part 52 is convexly formed on the upper part of the flat plate, and the interior of the reflective part 52 is complementary and concavely concave.

The reflective part 52 is closely attached to the substrate 3 and includes a horizontal part 521 having a through hole 520 into which the LED 32 is inserted, and an inclined surface formed to be inclined downwardly connected to the outer periphery of the horizontal part 521 ( 522).

The LED 32 is inserted through the through hole 520 and coupled to be accommodated in the reflection unit 52 , so that light does not leak into the space between the light transmitting panel 6 and the substrate 3 , and only within the reflection unit 52 . to be investigated.

Preferably, the angle θ1 between the horizontal portion 521 of the reflective portion 52 and the inclined surface 522 is 130 to 150° (see FIG. 4 ).

When the angle θ1 is 130 degrees or less, the irradiation range becomes narrow, and when it is 150 degrees or more, there is a possibility that it becomes excessive.

In addition, the reflector 52 of the diffuser 5 is formed with the width of the upper and lower light, and the width of the opening of the reflector 52 is such that the dispersion angle θ2 of the light emitted from the LED 32 is 90 to 110°. It is preferred that the length be set.

If the light dispersion angle (θ2) is 90° or less, the irradiation range becomes narrow, and when it is 110° or more, it may become excessive.

A coating film may be formed on the inclined surface 522 to exhibit reflective performance. The coating film may be formed by depositing a separate coating agent, or may be realized by the luster of the material itself.

The diffuser 5 may be provided in various shapes and colors. In the present invention, a diffuser of various colors can be selected as needed.

In the louver 7 , the light receiving groove 70 is disposed below the reflecting unit 52 of the diffuser 5 so that the light emitted from the reflecting unit 52 is concentrated into the light receiving groove 70 and is perpendicular only downward. direction can be irradiated.

The transmission hole 702 is formed to communicate with the light receiving groove 70 , and the transmission hole 702 is disposed to communicate with the opening of the reflection unit 52 , so that the light emitted from the reflection unit 52 passes through the transmission hole. It may be irradiated to the light receiving groove 70 .

Therefore, the light of the LED 32 is dispersed and emitted in the entire amount downward from the reflector 52,

The emitted light is usually emitted only downward through the light receiving groove 70 .

Therefore, the glare index can be lowered by not leaking light from the side, thereby relieving discomfort.

The frame portion 4 has a plurality of side frames 42 in close contact with the side ends of the plate 2 to form an edge, and a corner frame 44 coupled to the corners of a plurality of adjacent side frames 42 . is composed of

As shown in Figures 3, 5 and 7, the side frame 42 is stepped on the inside, so that the ends of the substrate 3 and the plate 2 are spanned and seated, and a plurality of A fastening groove 424 is formed, and a fitting groove 425 is formed in the inner side so that the end of the plate 2 is coupled.

The bent end 24 formed at the end of the plate 2 is fitted into the fitting groove 425, and a plurality of fitting grooves 425 are formed so that the bent end 24 of the plate 2 is fitted with a plurality of fitting grooves ( 425), so that the fitting position of the side frame 42 can be adjusted according to the size of the plate 2 by being selectively coupled to any one.

The corner frame 44 is formed at a right angle so that the side frames 42 are coupled to each other on both sides so that the fitting end 43 is formed, and the fitting end 43 is formed with a fitting jaw 432 inclined upward toward the inside. .

As shown in FIG. 7 , the fitting end 43 is formed to have a step difference t by being formed horizontally from the fitting start end and gradually inclined upward by the fitting jaw 432 .

Therefore, when the fitting jaw 432 is fitted into the fitting groove 425 of the side frame 42, it can be firmly coupled with the fitting groove 425 by force fitting due to an increase in the thickness by the step t, so that it is arbitrarily separated. This can be prevented.
