Description

Lamp

The invention relates to a luminaire, in particular to a luminaire capable of disassembling a lamp cover by means of a snap-on method.

Referring to FIG. 1 , the conventional lamp 8 generally includes a lamp body 81 and a lamp cover 82 . The lamp body 81 is internally provided with a necessary component such as a circuit board or a light-emitting module. The lamp cover 82 is a light-transmissive cover, and the lamp cover 82 is fixed to the open end of the lamp body 81 by using an adhesive.

When the conventional lamp 8 is illuminated, the circuit board and the light-emitting module inside the lamp body 81 generate high heat during normal operation, resulting in a gradual increase in temperature inside the lamp body 81; wherein the lamp cover 82 is used The adhesive is fixed to the lamp body 81. When the temperature inside the lamp body 81 is raised, the high temperature will cause the adhesive to become embrittled, and the lamp cover 82 is easily detached from the open end of the lamp body 81; In the assembly process of the conventional lamp 8 , the lamp cover 82 and the lamp body 81 must be glued, bonded, and the like to be fixed to each other, which is not only easy to cause inconvenience in assembly, but also causes poor bonding, and the lamp cover 82 and the lamp cover 82 The fixing of the lamp body 81 must use a large amount of glue, which causes an increase in the manufacturing cost of the lamp. In addition, after the lamp body 81 of the conventional lamp 8 is combined with the lamp cover 82, the ventilation structure design is not retained, and therefore, the overall heat dissipation effect is achieved. Poor, it is easy to reduce the service life of the lamp 8.
