Light-emitting diode lamp and light engine thereof

Abstract

The invention relates to a light-emitting diode lamp and a light engine adopted by the light-emitting diode lamp. The light-emitting diode lamp comprises an optical chamber, an electrical chamber and a heat radiating chamber, wherein the heat radiating chamber is arranged between the optical chamber and the electrical chamber; the optical chamber comprise at least one light-emitting diode light source and a light emergent passage; the electrical chamber comprises a shield and a circuit board; the heat radiating chamber comprises a heat radiator and a loop device; the heat radiator comprises an annular heat radiating base, a plurality of fins which are distributed at the peripheral surface of the heat radiating base, as well as a heat absorbing plate and a heating radiating cover plate which are respectively arranged at both ends of the heat radiating base; the heating radiating base, the heat absorbing plate and the heat radiating cover plate form a sealed cavity; the working fluid is filled into the cavity; the light-emitting diode light source is arranged on the outer surface of the heat absorbing plate; the loop device is arranged in the cavity and divides the cavity into an evaporating part, a condensing part, a steam passage and a reflux passage, and a capillary structure is filled into the reflux passage.

Description

technical field [0001] The invention relates to a semiconductor lighting device, in particular to a light emitting diode lamp and a light engine used therein. Background technique [0002] People's long-term over-reliance on fossil fuels not only causes energy shortages and high oil prices, which affects economic development, but also increases the concentration of global carbon dioxide and harmful gas emissions, leading to climate anomalies caused by global warming, ecological environment damage, and The harm to human existence is becoming more and more obvious. In order to sustainably manage the earth's ecological environment on which human beings depend, it is necessary to solve the energy crisis and environmental pollution problems at the same time. The development of new energy and renewable energy is the most important strategy to promote energy conservation and efficient use of energy , while traditional lighting consumes a considerable amount of energy, the developme...

AI Technical Summary

Problems solved by technology

[0004] The application of high-power and high-brightness LEDs in the new light source of lighting must cooperate with a high-efficiency heat dissipation mechanism to minimize the junction temperature of the LEDs in order to take advantage of the above-mentioned advantages. Otherwise, the luminous brightness and service life of the lighting device will be greatly reduced, affecting all And will make the energy-saving effect of the lighting device not obvious, and directly impact the reliability of the lighting device, cause serious light decay and even make the lighting device invalid
