An illumination device, comprising a lamp body (12, 22, 32) and a flow field device (182) disposed inside the lamp body (12, 22, 32). Between first air vents (1248, 2248, 3248, 4248) and second air vents (1848, 2848, 3848, 4844) on the lamp body (12, 22, 32), the flow field device (182) forms a forced air flow capable of flowing through a high-powered light source without flowing through other heat sources inside the lamp body (12, 22, 32); the first air vents (1248, 2248, 3248, 4248), the second air vents (1848, 2848, 3848, 4844) and the flow field device (182) are disposed in the same air chamber inside the lamp body (12, 22, 32), such that the heat generated by the light emission of a high efficiency light source can be quickly transmitted outside the lamp body. |
