The invention discloses a light-emitting diode (LED) reflector lamp with fins capable of radiating heat. The LED reflector lamp comprises a reflector lamp rear cover component, a core shaft component, a lamp panel, a light-reflecting cup and a reflector lamp front cover component, wherein the core shaft component comprises a core shaft cylinder and a plurality of radiating fins which are distributed on the outer peripheral surface of the core shaft cylinder uniformly; and an LED light-emitting chip is arranged on the lamp panel. The LED reflector lamp is characterized in that the reflector lamp rear cover component is clamped and connected with the upper part of the core shaft cylinder and the upper parts of the plurality of radiating fins; the lamp panel is fixed to the bottom of the core shaft cylinder and is wrapped by the plurality of radiating fins; and the reflector lamp front cover component is clamped and connected with the bottoms of the plurality of radiating fins, and the light-reflecting cup is clamped in an accommodating space formed by the lower part of the lamp panel and the lower parts of the plurality of radiating fins by the reflector lamp front cover component. In the process of assembling the LED reflector lamp, only the lamp panel is connected with the core shaft cylinder by a screw, and other parts can be clamped and connected directly without using the screw, so that the assembly efficiency is improved. Simultaneously, the temperature of the panel does not exceed 80 DEG C under the condition of no need of heat conduction of an aluminum substrate, so that materials are saved.
Description
technical field [0001] The invention relates to the technical field of LED spotlights, in particular to a finned heat dissipation LED spotlight. Background technique [0002] The semiconductor LED lighting source has the advantages of long life, energy saving, environmental protection, rich colors and miniaturization, so it is called the next-generation light source and has attracted much attention. With the continuous development of energy-saving technology, LED lights will be the development direction of the lighting industry in the future. [0003] With the country's support and promotion of the LED industry, LED lighting fixtures as light sources have gradually spread to various lighting devices, such as LED street lights, LED tunnel lights, LED fluorescent lights, LED chandeliers, LED projection lights, etc. [0004] One of the main factors restricting the development of LED lighting technology at this stage is heat dissipation, and the industry is also constantly impr...
