Description

technical field

[0001] The invention relates to a light-emitting diode lamp, in particular to a modularized light-emitting diode lamp with high light efficiency. Background technique

[0002] Traditional lighting sources consume a lot of energy. Semiconductor lighting using light emitting diodes (Light Emitting Diode, LED) is known for its high light efficiency, energy saving, longevity, environmental protection (mercury-free), fast start-up, strong light directionality, shock resistance and impact resistance. And other advantages, it has the potential to widely replace traditional lighting sources.

[0003] However, the use of LEDs in lighting devices must be combined with a high-efficiency heat dissipation mechanism to reduce the temperature of the LEDs in order to take advantage of the above-mentioned advantages. Otherwise, the light efficiency and service life of the LED lamps will be greatly reduced, and the impact will make the use of the LED lamps. The energy-saving ...
