Claim:
1. A luminous device, comprising: a base; a luminous element, disposed on the base, for providing light, and the luminous element comprising a body section, an anode section, a cathode section, a first luminous side surface, a second luminous side surface, a luminous top surface, and a luminous bottom surface; and a wavelength conversion unit, disposed on the luminous element, for converting a wavelength of the light emitting from the luminous element, the wavelength conversion unit comprising a first wavelength conversion side surface, a second wavelength conversion side surface, a wavelength conversion top surface, and a wavelength conversion bottom surface, wherein a difference value between a first distance and a second distance is less than a preset value, wherein the first distance is a distance between the first luminous side surface and the first wavelength conversion side surface or a distance between the second luminous side surface and the second wavelength conversion side surface, and the second distance is a distance between the luminous top surface and the wavelength conversion top surface; and a distance between the first wavelength conversion side surface and the first luminous side surface is less than a distance between the second wavelength conversion side surface and the first luminous side surface; a shape at a junction portion between the first wavelength conversion side surface and the wavelength conversion top surface is arc-shaped, and a shape at a junction portion between the second wavelength conversion side surface and the wavelength conversion top surface is arc-shaped; and a shape at a junction portion between the first luminous side surface and the luminous top surface is arc-shaped, and a shape at a junction portion between the second luminous side surface and the luminous top surface is arc-shaped.
