Abstract: Provided are a surface light source device and a backlight unit having the same. The surface light source device includes a main body with a plurality of lighting parts, and at least one electrode disposed on the lighting parts for discharging, said electrode being shaped in a partially different dimension depending the temperature difference(?t) in the lighting parts. The electrode compensates brightness uniformity lowering below a predetermined value due to the temperature difference(?t).

Abstract: A flat fluorescent lamp includes two panels 110, 120, 210, 220 disposed at an upper position and a lower position respectively; barriers 130, 230 forming discharge spaces 160, 260 which are provided with discharge gas; first bonding parts 140, 240 partially formed on the barriers 130, 230 to bond the barriers partially to the panel 110, 120, 210, 220; a second bonding part 150, 250 wholly formed between the two panels 110, 120, 210, 220 along peripheries of the two panels 110, 120, 210, 220 to wholly bond the peripheries of the two panels 110, 120, 210, 220; and electrodes 170, 270 for applying discharge voltage to the discharge gas.

Abstract: An improved composition and method for protecting both natural and artificial hair color from the harmful effects of ultraviolet radiation is provided. The composition includes melanin, an ultraviolet absorber, and a cationic surfactant. The composition may also include other ingredients such as additional cationic surfactants, hair conditioning agents, dispersing agents, rheology modifiers, emulsifiers, antioxidants, film formers, and water. A method of protecting hair color from ultraviolet radiation includes applying the composition to natural or artificial hair.
