Description

technical field [0001] The invention relates to a semiconductor lighting device, in particular to a light emitting diode lamp. Background technique [0002] People's long-term over-reliance on fossil fuels not only causes energy shortages and high oil prices and affects economic development, but also increases the concentration of global carbon dioxide and harmful gas emissions, leading to abnormal climate caused by global warming, destruction of the ecological environment, 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 development of lighting energy sa...

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

[0005] Existing fluorescent lamps are mainly composed of lamp tubes, rectifiers and starters. Because the luminous efficiency is about several times that of tungsten bulbs, it has become the most commonly used lighting device at present. Its light is based on the principle of airtight gas discharge. The specific structure is included in The inner wall of the vacuum glass tube is coated with fluorescent substances, and the inside is filled with inert gas (such as Argon, Neon or Krypton) and mercury vapor, and the tube is conducted through a rectifier that can generate high voltage. The electric current excites mercury atoms to produce gas discharge, and releases ultraviolet light and heat during the discharge process, and releases visible light after absorbing ultraviolet light through the fluorescent substance; different fluorescent substances will emit different visible light; however, the existing fluorescent lamps The main gas discharge substances are toxic mercury and fluorescent substances, and the accumulated waste from long-term use of fluorescent lamps will seriously pollute the environment
