As shown in fig. 2 and 3, the warning element 31 includes a warning lamp 311 connected to the first clamping element 221 and a pressing switch 312 provided on the cover glass 13, the warning lamp 311 is electrically connected to the pressing switch 312, the first clamping element 221 can drive the warning lamp 311 to move towards the pressing switch 312 to trigger the warning lamp 311 through the pressing switch 312, and the lamp light of the warning lamp 311 is different from the normal lamp light; the pressing switch 312 is electrically connected with the warning lamp 311, when the pressing switch 312 is pressed to trigger, the warning lamp 311 emits light, and the maintenance personnel can be prompted due to the fact that the color of the warning lamp 311 is different from that of normal light, so that the maintenance personnel can find abnormality in time.
In order to improve the difference between the light emitted by the warning light 311 and the light emitted by the light emitting component 12, the color of the warning light 311 may be selected differently according to the color of the light emitting component 12, preferably, the color of the warning light 311 and the color of the light emitting component 12 may be made to be complementary, for example, one of the light emitting component 12 and the warning light 311 is yellow, the other is purple, or one is orange, the other is blue, or one is red, the other is green, etc., and different selections may be made according to the actual situation.
It can be appreciated that, although the warning lamp 311 is disposed at the mounting cavity 111, and the first baffle 22 extends to the connection portion between the radiator 11 and the cover glass 13, the first baffle 22 does not completely block the cover glass 13, so that the warning lamp 311 can still penetrate through the cover glass 13 and bypass the first baffle 22 after emitting light, thereby enabling maintenance personnel to find out in time.
As shown in fig. 4 and 5, the warning member 31 includes a warning container connected to the first fastening member 221 and a warning liquid provided in the warning container, and the cover glass 13 is provided with a protrusion 131 piercing the warning container, so that the warning liquid adheres to the cover glass 13 and the light is different from the normal light; after the warning container is punctured, the warning liquid is released to the outside, the bulge 131 for puncturing the warning container is positioned at the position of the protective glass 13, and when the warning container is punctured, the warning container is positioned at the position close to the protective glass 13, so that the warning liquid is released to the position of the protective glass 13, the warning liquid is attached to the protective glass 13, the color of light transmitted by the protective glass 13 is changed, and maintenance personnel can find out in time.
