Technical Field
The invention relates to the field of illumination, in particular to a replaceable down lamp.

Therefore, a connecting wire with a GU24/E26 lamp cap and a connecting terminal is required to be connected to the general replaceable down lamp, and the lamp cap or the terminal is selected to be used when the replaceable down lamp is used. However, the cost is wasted, the design is bloated, and one wire terminal is wasted when the GU24/E26 lamp cap is selected for supplying power; GU24/E26 and one terminal are wasted when the terminal is selected to supply power.
Aiming at the requirement of the novel energy efficiency standard of the United states, two wiring modes are combined into one (an AC hole is formed in the upper surface of a GU24/E26 lamp holder for terminal power feeding), and a wiring terminal is removed, so that the problem is caused: when the terminal is adopted for power supply, the metal contact sheet of the GU24/E26 lamp holder is exposed outside, so that potential safety hazards are generated to people. North american line lights are typically powered from the AC side by a wire terminal plug and an AC power plug.
