An embodiment provides a motor comprising: a stator including a through hole; a cylindrical rotor which is disposed in the through hole; a rotor center shaft which is formed in the central region of the rotor and to which a rotary shaft is coupled; and a first magnet and a second magnet which are disposed between the stator and the rotor, wherein: the rotor includes an outer contour portion and a patterned portion formed between the outer contour portion and the rotor center shaft; the patterned portion includes a plurality of unit patterns and a hollow portion formed in each of the unit patterns; the outer contour portion includes an outer circumferential surface on which the first magnet and the second magnet are disposed and an inner circumferential surface which comes in contact with the plurality of unit patterns; the inner circumferential surface of the outer contour portion further includes a first protrusion portion protruding in a first direction toward the rotor center shaft; and in the first direction, the maximum length of the first protrusion portion is greater than the maximum length of each of the unit patterns.

Motor

Embodiments of the present invention relate to a phosphor plate and a lighting device including the phosphor plate, the phosphor plate according to an embodiment of the present invention has a light incident region on which light generated from a light source is incident and a light emitting region which converts a wavelength of the incident light and then outputs the light, wherein a ratio of a diameter of the light incident region and a diameter of the light emitting region ranges from 1:3 to 1:9.

Phosphor plate and lighting device including the same

The present invention relates to a phosphor plate comprising: a base plate; and phosphor included in the base plate, and provides a phosphor plate and a method for manufacturing the same, wherein one side of the phosphor plate comprises: a protrusion part formed by protrusion of the phosphor fixed to the base plate; and a recess part formed by separation of the phosphor from the base plate, the protrusion part being 20 to 70% with respect to the area of one side of the phosphor plate.

Phosphor plate and method for manufacturing the same

A lighting apparatus includes: a light source configured to generate laser beams; a light converter disposed in a direction in which the laser beams are emitted and configured to generate converted beams excited by the laser beams and transmitted beams of the laser beams; and a light housing disposed in front of the light converter, having an opening along a path of beam travel, and configured to adjust a light distribution of the converted beams.

Lighting apparatus with improved color deviation

Examples of the present invention relate to a phosphor plate composition having a wide emission region while improving luminance. The composition comprises: yttrium aluminum garnet (YAG) or gadolinium yttrium aluminum garnet ((Gd,Y)AG) phosphor powders doped with any one dopant selected from cerium (Ce), gadolinium (Gd) and neodymium (Nd); and a sintering agent of any one selected from lithium fluoride (LiF), magnesium oxide (MgO) and spinel (MgAlO).

Phosphor plate composition and phosphor plate for vehicle headlamp comprising same

Provided are a ternary glass composition containing SiO, BOand ZnO, and a ceramic phosphor plate including a glass frit obtained by vitrification of the glass composition as a matrix and obtained by sintering at least one phosphor.

Glass composition for photo-conversion member and ceramic photo-conversion member using the same

Provided is a glass composition for a ceramic phosphor plate, including: 75 to 85 mol % of an oxide mixture composed of SiO, BOand ZnO; 10 to 15 mol % of at least one carbonate compound including an alkali metal; and 1 to 5 mol % of AlO, wherein a content of BOis less than 25 mol %.
