Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, in an embodiment of the present invention, a high-power point light source lamp includes: the LED lamp comprises a lampshade 1, a lamp holder 2 and LED lamp beads 3, wherein the LED lamp beads 3 are arranged inside the lampshade 1, the LED lamp beads 3 are connected with a support rod 21, a boss is arranged at the upper part of the support rod 21, a spring 22 is arranged below the boss, the spring 22 is sleeved on the support rod 21, a gasket 23 is arranged below the spring 22, the spring 22 abuts between the boss of the support rod 21 and the gasket 23, the gasket 23 is sleeved on the support rod 21, the support rod 21 is connected with the lamp holder 2, a through hole is formed in the bottom surface of the lampshade 1, the support rod 21 penetrates through the through hole in the bottom surface of the lampshade 1, and the bottom surface of the lampshade 1 is fixed between the gasket 23 and the lamp holder 2;

the lampshade 1 is bowl-shaped, the end face of the lampshade is a flat plate made of transparent material, such as a glass plate, the end part of the lampshade 1 is provided with a movable opening window 11, the opening window 11 is connected with the lampshade 1 through an automatic adjusting mechanism 12, the automatic adjusting mechanism 12 comprises a loop bar 121, a shape memory alloy sleeve 122 and a pressure spring 123, the shape memory alloy sleeve 122 is movably sleeved on the loop bar 121, the shape memory alloy sleeve 122 is made of copper-zinc alloy materials, the pressure spring 123 is positioned at the end part of the shape memory alloy sleeve 122 and sleeved on the loop bar 121, the edge of the opening window 11 is fixedly connected with a sliding block 111, the sliding block 111 is fixedly connected with the shape memory alloy sleeve 122, the opening window 11 and the end face of the lampshade 1 form an integral circular lampshade structure, and when the LED lamp beads 3 generate heat for a long time due to the fact that the temperature in the lampshade 1 rises, the shape memory alloy sleeve 122 recovers the shape thereof, specifically, the length of the shape memory alloy sleeve 122 is changed, so that the opening window 11 is driven to move, the opening window 11 is separated from the end face of the lampshade 1, the end face of the lampshade 1 is opened, heat flow and heat dissipation in the lamp body are facilitated, heating of the lamp body is reduced, and the service life of the lamp is prolonged and the stability of the lamp is improved.
