In a light irradiating unit in which a plurality of illuminants are arranged on a curved face, the present claimed invention intends to get a light irradiating unit easy to manufacture and with a big light volume, stable in the luminous intensity and superior in life duration. The light irradiating unit comprises an illuminant loading member 2 that has a curved illuminant loading face 2c on which a plurality of illuminants 1 are loaded, a holding frame 3 that holds the illuminant loading member 2 and a tabular heat-dissipating member 6 that has predetermined elasticity and/or flexibility, and the heat-dissipating member 6 is generally tightly attached to a back face 2d of the illuminant loading face 2c and a supporting face 31a of the holding frame 3 that faces to the back face 2d of the illuminant loading face 2c respectively by making use of the elasticity and/or flexibility.
A light irradiating unit comprises an illuminant loading member that has a curved illuminant loading face on which a plurality of illuminants are loaded, a holding frame that holds the illuminant loading member and a tabular heat-dissipating member that has predetermined elasticity and/or flexibility, and characterized by that the heat-dissipating member is generally tightly attached to a back face of the illuminant loading face and a supporting face of the holding frame that faces to the back face of the illuminant loading face respectively by making use of the elasticity and/or flexibility.
A lighting unit comprising a plurality of illuminants, a toric print substrate that can be curved along a direction of its thickness and that has a cutout at a part thereof and a heat-dissipating member that is in a same shape or in a generally same shape in a plane view as that of the print substrate and that can be curved along a direction of its thickness, characterized by that the print substrate is held in a tabular state or a generally tabular state and a plurality of illuminants are loaded on an illuminant loading face set on one of the faces thereof, and then one side of the cutout of the print substrate loaded with the illuminants and the other side of the cutout are jointed or proximately held to form the print substrate in a shape of a cone frustum so that the illuminant loading face locates in a concave side, or that one side of the cutout of the print substrate and the other side of the cutout are jointed or proximately held to form the print substrate in a shape of a cone frustum so that the illuminant loading face locates in a concave side, and then a plurality of illuminants are loaded on the illuminant loading face, and in the meanwhile the heat-dissipating member is formed to be in a shape of a cone frustum by jointing or proximately holding one side of a cutout provided on the heat-dissipating member and the other side of the cutout and a contact face arranged at a concave face of the heat-dissipating member is tightly attached to a back face of the illuminant loading face of the print substrate.
