A light device includes a light bulb set and a thermal diffusion guide disposed around the light bulb set. The light bulb set has an outer wall. The thermal diffusion guide keeps a distance from the outer wall to form an air passage for restricting an air flow to flow through. The thermal diffusion guide has an outer rim forming a first air surface between the rim and the outer wall for collecting the air flow to flow into the air passage, so as to increase thermal diffusion efficiency. The present invention further discloses a light device, including a light bulb set, a shield above the light bulb set and a diffusion plate above the shield. A first air isolation layer is formed between the shield and the diffusion plate.
