Abstract: A fragrance lamp structure including a carrying element, a lighting element and a driving element is provided. The carrying element has a carrying surface, a first contact surface and a second contact surface. The carrying surface and the first contact surface are opposite to each other, and so are the carrying surface and the second contact surface opposite to each other. The lighting element has a first heat output surface facing the first contact surface of the carrying element. The lighting element generates a first heat going through the first heat output surface and the first contact surface to heat up the carrying element. The driving element has a second heat output surface facing the second contact surface of the carrying element. The driving element generates a second heat going through the second heat output surface and the second contact surface to heat up the carrying element.

Abstract: A backlight module that includes a light guide plate, a point light source having a light emitting surface, a first brightness enhancement film disposed above the light guide plate, and a second brightness enhancement film disposed between the light guide plate and the first brightness enhancement film is provided. The light guide plate has a rectangular pre-display area. A reference line intersects a margin of the rectangular pre-display area in 45 degrees. A normal of the light emitting surface intersects the reference line in a first included angle with ±18 degrees based on the reference line. The first brightness enhancement film has first prism structures extended in a first extending direction intersecting the normal in a second included angle with ±25 degrees based on the light emitting surface. The second brightness enhancement film is disposed between the light guide plate and the first brightness enhancement film.

Abstract: A backlight module includes a frame, a reflective sheet, a light guide plate, a light source, and an optical film set. The frame defines an accommodation space, and the reflective sheet is disposed in the accommodation space. The light guide plate is disposed in the accommodation space and on one surface of the reflective sheet. The optical film set is disposed one side of the light guide plate opposite the reflective sheet. The reflective sheet is hollowed out at a position overlapping the light source to form at least one opening so as to reduce light halos.
