Mushroom-shaped lamp

Abstract

The invention provides a mushroom-shaped lamp. The upper end of a lampshade of the mushroom-shaped lamp is provided with an upper cover with mesh holes; a first installing plate with a first notch is arranged in the circumferential direction of the upper cover; a stair-shaped counter bore composed of a first installing hole and a second installing hole is formed in the upper side of a base; a plurality of first through holes are formed in the outer edge of the bottom of the first installing hole; a penetrating hole is formed in the outer edge of the bottom of the second installing hole; a plurality of second through holes are formed in the circumferential direction of the lower portion of the base; the second installing hole is internally provided with a positive electrode elastic piece and a negative electrode threaded opening; the upper ends of two cables of a cable outgoing line are electrically connected with the positive electrode elastic piece and the negative electrode threaded opening; the lower portion of the lampshade is screwed into the first installing hole; a bulb-shaped light source connector is in screwed connection with the negative electrode threaded opening and makes contact with the positive electrode elastic piece; the second through holes, a base inner cavity, the first through holes, a lampshade inner cavity and the mesh holes form a cooling channel; a second installing plate and a third installing plate arranged in an up-down spaced manner and correspondingly provided with a second notch and a third notch are arranged in the circumferential direction of the base; cooling fins are inserted in the first notch, the second notch and the third notch; and the upper portions of the inner sides of the cooling fins make close contact with the lampshade through silicone grease layers. The mushroom-shaped lamp is good in cooling performance and long in service life.

Description

technical field [0001] The invention relates to a mushroom lamp. Background technique [0002] Existing desk lamps are monotonous in shape, and mostly use incandescent bulbs as light sources. The incandescent bulbs generate a lot of heat after being lit, and the desk lamps are airtight structures, so the heat is not easy to discharge. Long-term use will easily cause the desk lamps to overheat, which will affect the service life of the desk lamps. cause negative impact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mushroom lamp with good heat dissipation performance and long service life. [0004] In order to solve the above technical problems, the present invention provides a mushroom lamp, which includes a lampshade, a base, a positive pole shrapnel, a hollow negative pole screw, a bulb-shaped light source, and a cable lead wire. The lampshade is transparent or translucent, and its material is glass Mater...
