Lighting apparatus

A lighting apparatus, comprising:

• an optical component housing having an optical container and an entrance opening, wherein the entrance opening is disposed on a lateral side of the optical component housing, wherein the optical component housing has a light escape side, wherein the lateral side is at a different plane as the light escape side;
• an optical component detachably inserted into the optical container via the entrance opening;
• a cover manually operable to reveal the entrance opening for inserting the optical component and operable to conceal the entrance opening;
• and
• a light source, wherein a light is emitted from the light source passing through the optical component and escaped from the light escape side, wherein the optical container has an extra space for storing an electronic device, wherein the optical component housing has an electrode, wherein when the optical component is inserted to the container, the electrode electrically connects the electronic device to a controller for the light source, wherein the electronic device stores an identifier to inform the controller of a type of data of the optical component.
