Illuminating apparatus and light source engine thereof

Abstract

An illuminating apparatus comprises: an optical chamber consisting of a light source and a light-emitting channel so as to provide required illuminating brightness and luminescence properties as well as light source protection; an electric control room used for providing a driving power, a control circuit and power management needed by the light source; and a heat-dissipation room arranged between the optical chamber and the electric control room and comprising at least one U-shaped heat pipe, a plurality of fins and at least one installation firmware, wherein the U-shaped heat pipe comprises an evaporation section arranged at the bottom thereof and two condensation sections arranged at two sides thereof; the fins are arranged at intervals and arranged at the condensation sections at the two sides of the U-shaped heat pipe in a penetrating way; the installation firmware spans on the evaporation section of the U-shaped heat pipe; and the heat-emitting part of the light source is in tight hot connection with the evaporation section of the U-shaped heat pipe by the installation firmware so as to transmit and remove heat released when the light source emits light.

Description

Technical field [0001] The invention relates to a lighting device, in particular to a semiconductor lighting device and its light source engine. Background technique [0002] People's long-term excessive dependence on fossil fuels has not only caused energy shortages and high oil prices to affect economic development, but also increased the global emission of carbon dioxide and harmful gases, leading to climate abnormalities, ecological damage, and environmental damage caused by global warming. The hazards to human survival are becoming increasingly apparent. In order to sustainably manage the earth’s ecological environment on which humans depend, the energy crisis and environmental pollution must be solved at the same time. The development of new and renewable energy is the most important strategy to promote energy conservation and efficient use of energy. , And traditional lighting consumes considerable energy. The development of lighting energy saving will be the most importan...

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
