Description

TECHNICAL FIELD

[0001] The present application relates to the field of stage lamp lighting technology, and in particular to a stage lamp capable of maintaining good light effect. BACKGROUND

[0002] Since the internal components of the lamp generate heat during operation, the sealing of the lamp causes the internal temperature of the lamp to rise uniformly, thereby forming a large temperature difference between the inside and outside of the lamp. A large temperature difference can easily cause high-temperature evaporated oil gas to condense on the lens, and a large temperature difference can also cause water mist to be generated, thereby causing the light-emitting lens to exhibit a misting effect, which affects the light performance. In order to solve the lens contamination problem, a tempered glass is generally provided at the light-emitting opening of the lamp to solve the problems of water resistance and attachment of the lens, but the internal and external temperature difference of the lamp can still cause the tempered glass to condense water mist or oil stains, thereby affecting the light effect.
