Description

Anti-glare lighting {Anti-glare lighting}

The present invention relates to an anti-glare lighting, which blocks light at an angle that is directly irradiated into the eyes of an indoor occupant so as to prevent glare from the lighting indoors, but only irradiates this light into the irradiation area to prevent glare and increase the intensity of illumination. It relates to anti-glare lighting that can be increased.

A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapor, and when current flows between the ionized gases between the metal electrodes at both ends, a significant amount of ultraviolet light is emitted while emitting light. To absorb this, the inside of the glass tube absorbs the ultraviolet light. It is coated with a phosphor that emits light and a fluorescent material that re-emits ultraviolet energy as visible light.

The light of a fluorescent lamp has a very strong glare, so when looking straight at it for a long time, it has a significant effect on deteriorating eyesight.

Therefore, when exposed to these ultraviolet rays for a long time, a yellowing phenomenon occurs in pictures, wallpaper, and painted parts installed indoors, so that considerable attention must be paid.

When installing a fluorescent light fixture as a means to prevent glare, a louver plate equipped with a plurality of louvers in a lattice form is installed below the fluorescent light fixture, and if you look at the louver-type fluorescent light fixture installed on the ceiling from the side out of a predetermined angle, it is covered by the lower loubar. The glare is prevented by preventing the fluorescent lamp inside from being directly visible.

On the other hand, the conventional lighting lamp has a strong glare even when a lampshade is combined with a fluorescent lamp and a louver is used at the bottom, which is inconvenient. In other words, there was a disadvantage that the glaze was high.

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

As shown in Figures 1 to 10, the anti-glare lighting (A) according to the present invention, the attachment portion 22 attached to the ceiling is formed on the upper surface of the plate (2); A substrate 3 attached to the lower surface of the plate 2 and equipped with an LED 32 on the lower surface; Attached to the bottom surface of the substrate 3, the coupling hole into which the LED 32 is inserted is formed on the top, and the width expands toward the bottom, and the reflector 52 having an inclined surface 522 formed on the inner circumferential surface Diffuser 5; a light transmitting panel 6 attached to the lower surface of the diffuser 5; a louver 7 attached to the lower surface of the transparent panel 6, having a light receiving groove 70 corresponding to the reflecting part 52, and having a lattice-shaped partition wall 72; Coupling pins 8 penetrating the partition wall 72 of the louver 7 and combining the light transmitting panel 6, the diffuser 5, the substrate 3, and the plate 2 to be integral; A frame portion 4 composed of a side frame 42 that is in close contact with the side end of the plate 2 to form a border and a corner frame 44 coupled to the corners of a plurality of adjacent side frames 42; It is composed of.

The plate 2 can be manufactured in various sizes and shapes as needed, and is made of a rectangular panel as an example.

Mounting bolts (not shown) pre-formed on the ceiling may pass through the attachment part 22 on the upper surface of the plate 2, and then nuts may be fastened and mounted at the lower part.

The substrate 3 includes a PCB (not shown) in which a plurality of LEDs 32 are planted, and the LEDs may emit light by supplying power through wires connected to the outside.

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

The reflector 52 is closely attached to the substrate 3 and has a horizontal portion 521 formed with a through hole 520 into which the LED 32 is inserted, and an inclined surface formed following the outer periphery of the horizontal portion 521 and inclined downward ( 522).

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

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

If the angle θ1 is 130° or less, the irradiation range becomes narrow, and if it is 150° or more, there is a possibility that it may become 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 desirable that the length be set.

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

A coating film may be formed on the inclined surface 522 so that reflective performance can be exhibited. The coating film may be formed by depositing a separate coating agent, or may be realized by the gloss of the material itself.

The diffuser 5 may be provided in various shapes and colors. In the present invention, it is possible to select a diffuser of various colors as needed.

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

A 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 reflector 52 so that the light emitted from the reflector 52 passes through the transmission hole. It may be irradiated into the light receiving groove 70 .

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

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

Therefore, since light does not leak at all from the side, the glare index can be lowered, and discomfort can be eliminated.

The frame part 4 includes a plurality of side frames 42 that are in close contact with the side end of the plate 2 to form an edge, and a corner frame 44 coupled to the corner of the plurality of side frames 42 adjacent to each other. It consists of

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 has a plurality of fitting grooves ( 425) can be selectively coupled to any one of them so that the fitting position of the side frame 42 can be adjusted according to the size of the plate 2.

The corner frame 44 is formed at right angles, and fitting ends 43 are formed so that the side frames 42 are coupled to each side, and the fitting ends 43 are formed with fitting jaws 432 inclined upward toward the inside. .

As shown in Figure 10, the fitting end 43 is formed to have a step (t) by being formed horizontally from the beginning to be fitted and then the fitting jaw 432 is gradually inclined upward.

Therefore, when the fitting jaw 432 is fitted into the fitting groove 425 of the side frame 42, due to the thickness increase by the step (t), it can be firmly coupled to the fitting groove 425 and the fitting groove 425 with an interference fit, which is arbitrarily separated. this can be prevented.

Meanwhile, as shown in FIG. 11, according to another embodiment, the side frame 42 has a step 427 formed on the inside, so that the ends of the substrate 3 and the plate 2 can be seated across, and the step A coupling groove 424 is formed on the inside of the 427, and at least one fitting groove 425 is formed on the upper surface of the stepped 427 so that the end of the plate 2 is coupled, and the inner surface of the stepped 427 A coupling groove 428 is formed.

A fitting protrusion 722 is formed at the end of the louver 7, and the fitting protrusion 722 is fitted into the coupling groove 428 of the step 427.

In addition, the end of the light transmitting panel 6 is fitted into the coupling groove 428. According to this structure, both ends of the louver 7 and both ends of the light transmitting panel 6 are pushed into the side frame 42 in a slightly bent state, and when they reach the coupling groove 428, they are stretched by the elastic restoring force and the light transmitting panel Since (6) and the louver (7) can be fitted, the configuration can be simplified and the fastening operation can be facilitated.

The 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 a high-luminance light source or light of a reflective object within the field of view, or a state in which discomfort is felt due to glare.

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

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

Disability glare is glare that momentarily loses visual function or reduces eyesight when an extremely bright light source, such as a car headlight, enters the field of view.

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

Veiling Reflection and reflective glare are glare that makes objects difficult to see when light from a light source or window with high luminance is reflected on the surface of a monitor, desk surface, or glossy paper and enters the field of vision.

As a way to control the glare, a translucent diffusion plate, a prism panel, a light shield, or a louver is used.

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

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 design, it is possible to prevent discomfort by reducing the glare zone.

Since the glare zone occurs within the field of view within 45 degrees from the line of sight, we tried to reduce it.

The UGR ratings are shown in [Table 1].

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

Generally, 19 is appropriate for the UGR standard, and is indicated as UGR=19. For most offices, UGR 16-19 is adequate.
