Description

Electric lamp lead cooling cover

Technical Field

The utility model relates to the technical field of lighting fixtures, especially, relate to an electric light lead wire cooling lid.

Background

Any object emits radiation energy and absorbs the radiation energy from the surrounding objects. The radiation power of the object increases rapidly with the temperature. Generally, when an object is subjected to radiation projected by another object, a portion of the radiation is converted to thermal energy and a portion is converted to reflected thermal energy. The existing stage lamps are generally provided with heat insulation filters and color sheets. The thermal spacers can absorb infrared radiation and then dissipate the heat through the glass material. The color sheet may allow light transmitted through the color sheet to exhibit a designated color.

The lamp bulb emits light with relatively high radiant energy. When passing through the thermal barrier filter and the color filter, the radiant energy reflects a portion of the energy onto the wire (the reflected energy can be understood as reflected light), resulting in an increase in the temperature of the wire. In the prior art, the lead wire is usually wrapped by using lamp mud to block light reflected to the lead wire, so that the effect of cooling is achieved. Due to the problems of the materials of the lamp mud, the penetration of light cannot be completely blocked, and in addition, the self heating of the lead wire easily generates carbonization and sealant leakage; once carbonized, the heat is absorbed sharply, which leads to the lead being blown and may even cause safety accidents.
