Compact safer tightly secured lighting system

A compact safer tightly secured lighting system comprising:

• an illumination element module composed of a heat sink and a lamp housing, a top end of the lamp housing connected to a bottom end of the heat sink, wherein a middle at the bottom end of the heat sink is recessed with a slot, and a top end in the slot is disposed with an illumination element, and an outer wall at a lower end of the heat sink has a circular recess, and the recess is provided for embedding a temperature controller, and the illumination element is electrically connected to the temperature controller;
• the lamp housing composed of an external case, a reflective cup, a protection mask and a plurality of circlips having elasticity, wherein a top end of the external case is locked and connected to the bottom end of the heat sink;
• the reflective cup disposed in the external case, a top end of the reflective cup stretched from the top end of the external case and stretched into the slot of the heat sink, the reflective cup located below the illumination element;
• the protection mask disposed in the external case and located below the reflective cup, a spacing contained between an outer wall of the protection mask and an internal wall of the external case;
• the circlip disposed to the outer wall of the protection mask, where one end lap-connected to a top end of the protection mask while another end has a tooth buckle corresponding to the internal wall of the external case, the tooth buckle stretched into the spacing so that the circlip locates between the external case and the protection mask to allow the tooth buckle to paste the internal wall of the external case and the outer wall of the protection mask;
• a terminal box electrically connected to the temperature controller and the illumination element through an electric wire and having an upper lid and a lower lid and locked and connected to the upper lid and the lower lid through a locking mechanism;
• an illumination element module driver electrically connected to the terminal box through an electric wire;
• a junction box electrically connected to the illumination element module through an electric wire.
