[0003] Generally, the human eye has limited acceptance of the brightness of the light emitted by the luminaire. When the brightness of the light entering the human eye is too low, the human eye is difficult to distinguish the object, and when the glare enters the human eye, it is easy to irritate the person. The eye 'causes the human eye to produce a "glare" phenomenon, and causes the ability of the human eye to distinguish and reduce vision. In the prior art, if the brightness of the light is too low, the effect of improving the human eye can be improved by increasing the luminous intensity of the lamp, but the generation of the glare is related to the luminous intensity of the illuminator in the luminaire, and the other The aspect also depends on where the observer is. Eliminating glare in prior art is a technical challenge in the industry. In view of the above, it is particularly important to provide an indoor luminaire having an anti-glare function.

An indoor light fixture with anti-glare function will be described below by way of example. [0006] An indoor light fixture comprising at least one light cover, a light emitting element and an optical sheet. The lamp cover defines a receiving space, and the lamp cover has an opening corresponding to the outside of the receiving space; the at least one light emitting component is disposed in the receiving space of the lamp cover. The optical sheet is disposed at an opening of the lamp cover and selectively covers a portion of the opening, the optical sheet reducing the brightness of light exiting through the partial region. Compared with the prior art, the optical sheet can reduce the brightness of the light emitted from the partial region by selectively covering a partial region of the opening of the lamp cover, thereby effectively preventing glare, so that the indoor lighting device has better illumination. effect. [0008] The following is a detailed description of an embodiment of the present invention with reference to the drawings. [0009] Referring to FIG. 1, a first embodiment of the present invention provides an indoor luminaire 10 having an anti-glare function, which includes a The light-emitting element 12, a lamp cover 14 and an optical sheet 16.

The area is n. In this embodiment, the optical sheet 16 is a diffusion sheet. [0013] The indoor light fixture 1 further includes a connection hook 18. One end 180 of the connecting hook 18 holds the optical sheet 16 , and the other end 182 is movably connected to the flange 14 并可 and slidable along the flange 14 ′ when the connecting hook 18 slides along the flange 14 , The optical sheet 16 is rotatable about a central axis of the opening ι42. [0014] The indoor light fixture 1 can be used in indoor lighting. As shown in Fig. 2, the light I emitted by the light-emitting element 12 has an exit angle 0 (the angle between the light I and the vertical). When the optical sheet 16 does not cover the partial region ,, the light I can be directly irradiated onto the table top 200 (shown by a broken line I in FIG. 2) and reflected on the desktop 200 to enter the human eye. People feel the glare caused by reflected light. When the optical sheet 16 covers the partial region material, the light I is irradiated onto the optical sheet 16 and diffused, and the light I is emitted through the optical sheet 16 and then emitted to the outside world in a direction away from the human eye ( As shown by the solid line II in Figure 2). As a result, the brightness of the light passing through a portion of the river is reduced, which prevents the reflected light from entering the human eye and achieves the purpose of preventing glare. Generally, the optical sheet 16 has a better anti-glare effect for light having an incident angle of 0 to 3 Torr to Μ. It should be noted that for other areas not covered by the optical sheet 16, the light I can exit directly to the outside through the opening 142 for normal illumination. 097149769 Form No. 1010101 Page 5 of 18 1003441998-0 1362460 November 28, 100 Pressing the page ¥ [0015] The optical sheet 16 is rotatable about the central axis of the circular opening 142, and the user can The position of the optical sheet 16 is selectively adjusted at the position of the optical sheet 16 so that the optical sheet 16 achieves an optimum anti-glare effect. [0016] In order to provide the optical sheet 16 with a better anti-glare effect, the optical sheet 16 may have a transmittance of less than or equal to 80%. Preferably, the optical sheet 16 has a transmittance of less than or equal to 60%. [0017] Of course, the optical sheet 16 is not limited to the diffusion sheet, and may also be an anti-dazzling screen, a reflector, a filter, such as a neutral density filter ( Neutral density filter), bandpass filter, bandpass filtef, etc., or other types of optical sheets, as long as they reduce the brightness of light entering the human eye. When the optical sheet 16 is a band pass filter, it has a better anti-glare effect for visible light having a wavelength range of 410 nm to 780 nm. [0018] Further, the second embodiment of the present invention provides an indoor light fixture 30, which is substantially the same as the indoor light fixture 10 provided by the first embodiment, except that the optical sheet 36 is a light deflecting sheet. The utility model comprises a zigzag structure with a plurality of arrays arranged, and the light emitted by the light-emitting element 32 is deflected by the saw-tooth structure of the light deflecting sheet 36, and the direction of the deflection also prevents the light from occurring on the desktop 300. The glare caused by reflection and entering the human eye. Similarly, the optical sheet 36 has a better anti-glare effect for light having an incident angle of 0 to 30 degrees to 75 degrees. [0019] The optical sheet does not necessarily need to be connected to the hook to hold it, such as 097149769 Form No. A0101 Page 6 / 18 pages 1003441998-0 1362460 100 years. November 28, according to the replacement page Figure 4 As shown in the figure, the third embodiment of the present invention provides an indoor light fixture 40 that differs from the indoor light fixture 10 provided in the first embodiment in that the light cover 40 further includes a light transmissive cover 43 and a light cover 43 44 is substantially matched to seal the opening 442, and the light transmissive cover 43 is located between the light-emitting element 42 and the optical sheet 46, and the optical sheet 46 is selectively attached to the light-transmitting cover by one of the adhesive faces 460 thereon. 43 on. [0020] The translucent cover 43 is a transparent body for adjusting the illumination range of the light-emitting element 42 by optically adjusting the direction of the light emitted by the light-emitting element 42, for example, optically diverging or optically focusing the light. The optical sheet 46 can be selectively attached to the translucent cover 43 according to the position of the user to achieve an optimum anti-glare effect.
