  • the heat sink is secured into a recess in the elastic holder through an elastic retaining member.
  • This embodiment is particularly advantageous as the heat sink can be securely held in place, and the light source can be reliably cooled.
  • the elastic holder has an elastic sleeve that firmly accommodates one end of the optical waveguide adjacently to the light source. This embodiment is particularly advantageous as the optical waveguide can be safely secured relative to the light source.
  • the elastic sleeve has an extended rear section that is filled with a moldable optical silicone adjacently to the light source, and a front section that firmly accommodates a glass rod which is serially coupled with the moldable optical silicone.
  • This embodiment is particularly advantageous as the moldable optical silicone can be flexibly bent around the corners, and thus the light source can be located at a position that is comparatively cold.
  • the extended rear section is respectively straight or curved.
  • the elastic sleeve has a funnel shaped opening so as to receive the respective end of the optical waveguide. This embodiment is particularly advantageous as the optical waveguide can be easily assembled with the elastic holder.
  • the elastic sleeve has a stopper that restricts backward movement of the optical waveguide. This embodiment is particularly advantageous as the adjacent light source can be effectively protected from excessive mechanical stress.
  • the elastic holder is a single piece made from a suitable silicone rubber.
  • This embodiment is particularly advantageous as the illuminating device can be easily assembled with the optical waveguide, the light source, and the heat sink beforehand. Thereafter, the illuminating device can be easily installed into the appliance by means of the elastic suspension member.
  • the other end of the optical waveguide is secured into a through hole on the ceiling by means of coupling means such that the light beam emerging from the optical waveguide impinges onto the center region of the cooking chamber.
  • This embodiment is particularly advantageous as the user can clearly see the cooked product when the illuminating device is switched on.
  • the illuminating device is located in close proximity to the upper front part of the cooking chamber. This embodiment is particularly advantageous as the the cooked product can be more intensively illuminated from the front side which is exposed to the user.
  • the cooking appliance is provided as a free-standing type appliance or a built-in type appliance.
  • the cooking appliance may also be provided with a cooking top in addition to the cooking chamber.
