In addition, the protective frame 40 ensures the effective irradiation of the lamp body 30 to avoid damage to the lamp body 30. The body 30 is blocked by an object at a relatively short distance, causing the light of the lamp body 30 to be blocked. The distance between the shield and the lamp body 30 is enlarged through the protective frame 40 to ensure that the light has a space to spread, and the setting of the protective frame 40 can prevent objects from contacting the lamp body 30. The short distance leads to possible safety accidents caused by heat accumulation.
