NOVELTY - An LED embedded light comprises a housing component, a lighting unit, a heat dissipation unit, and a locking fixing unit. The lighting unit includes a circuit board on which an LED module is mounted, several light emitting units from which the light of the LED module is emitted, and several diffusing lenses respectively arranged on the front surface of the light emitting part to diffuse and emit the light of the LED module. The heat dissipation unit includes a heat dissipation unit (A) having a large diameter and a heat dissipation unit (B) having a small diameter. The heat dissipation unit (A) is arranged at a predetermined interval within the heat dissipation unit (A), and an outer surface of the heat dissipation units (A) and (B) is coated with a heat dissipation coating layer. The heat dissipation coating layer contains 1-3 pts. wt. silica and 2-5 pts. wt. alumina based on 100 pts. wt. of the resin, 2-5 pts. wt. cobalt oxide and 4-6 pts. wt. graphene oxide. USE - LED embedded light. Uses include but are not limited to lighting lights, building decoration lights, c, vehicle lights, traffic lights, indoor and outdoor electric signs, induction lights, warning lights, light sources for various security equipment, and light sources for sterilization or disinfection. ADVANTAGE - The LED embedded light has improved heat dissipation performance and fire resistance characteristics, and is easy to install and disassemble so as to be conveniently dismantled when buried or dismantled. The lighting angle is adjustable. DETAILED DESCRIPTION - An LED embedded light comprises a housing component installed by fitted into a perforated mounting hole of a ceiling, a lighting unit detachably mounted to the housing component, a heat dissipation unit mounted on the lighting unit to dissipate heat generated from the lighting unit to the outside, and a locking fixing unit installed on the upper surface of the housing component to fix the housing component inside the perforated mounting hole of the ceiling. The lighting unit includes a circuit board on which an LED module is mounted, several light emitting units from which the light of the LED module is emitted, and several diffusing lenses respectively arranged on the front surface of the light emitting part to diffuse and emit the light of the LED module. The heat dissipation unit includes a heat dissipation unit (A) having a large diameter and a heat dissipation unit (B) having a small diameter. The heat dissipation unit (A) is arranged at a predetermined interval within the heat dissipation unit (A), and an outer surface of the heat dissipation units (A) and (B) is coated with a heat dissipation coating layer. The heat dissipation coating layer contains 1-3 pts. wt. silica and 2-5 pts. wt. alumina based on 100 pts. wt. of the resin, 2-5 pts. wt. cobalt oxide and 4-6 pts. wt. graphene oxide. The LED device is mounted in the space between the housing component and the lighting unit, and further comprises a pair of rotation units for controlling the irradiation direction of the lighting unit, including a cover component provided with a seating groove on the inside and a ball component coupled to the seating groove of the cover component. The cover component is integrally coupled to one end of the connecting component (a), and the ball component is integrally coupled to one end of the connecting component (b). The upper extremity connecting component (a1) is freely rotated at the end of the connecting component (b1) so that the user can adjust the lighting unit to a desired angle.
