Illuminating apparatus and light engine thereof

Abstract

The invention relates to an illuminating apparatus and a light engine thereof. The illuminating apparatus comprises an optical room, an electric room and a heat dissipation room, wherein the optical room consists of at least one light source and a light-emitting channel and is used for providing required illumination distribution, luminescence property and light source protection; the electric room is used for providing a driving power supply, a control circuit and power supply management needed by the light source; and the heat dissipation room is arranged between the optical room and the electric room and comprises at least one L-shaped thermotube, a plurality of fins and at least one saddle, the L-shaped thermotube comprises an evaporation section and a condensation section, the fins are arranged at intervals and inserted into the condensation section of at least one L-shaped thermotube, and the saddle rides on the evaporation section of the L-shaped thermotube and hotly links a heat-emitting part of the light source and the evaporation section of the L-shaped thermotube tightly to transmit and remove the heat released by the light source during luminescence.

Description

technical field [0001] The invention relates to a lighting device and its light engine, in particular to a semiconductor lighting device with high heat dissipation efficiency and its light engine. 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 consid...

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
