However, the existing projection lamp has many problems in practical application. On the one hand, from the heat dissipation performance, due to the unreasonable structure design of the traditional projection lamp, the heat accumulates in the lamp body, and the heat dissipation effect is poor. For example, the distance between the chip and the heat dissipation part is too long, and the heat dissipation channel is not reasonably designed, so that the heat generated by the chip cannot be dissipated in time during the long-time working process of the projection lamp, thereby affecting the performance and service life of the chip. In severe cases, it cannot meet the continuous working requirements of the projection lamp, greatly reducing the practicability and reliability of the projection lamp. On the other hand, when installing and adjusting the projection lamp on the carrier, a transition connecting piece is usually needed to realize the installation.
