In this embodiment, the distances from the two electrical holes 1001 to the center of the back of the heat sink 10 are not equal.

Specifically, referring to fig. 10, the distances "x" and "y" between the two electrical connectors a and B fixed to the rear cover 13 and the center of the rear cover are different, that is, x ≠ y; the distance "u" and "v" between the two air holes a and B on the heat sink 10 and the center of the module are different, i.e. u is not equal to v; but the distance "x" between the electrical connector a and the center of the rear cover is equal to the distance "u" between the electrical hole a on the heat sink and the center of the module, that is, x is equal to u; the distance "y" between the electrical connector B and the center of the rear cover is equal to the distance "v" between the electrical hole B on the heat sink and the center of the module, that is, y is equal to v.

When the electric hole A on the LED module is assembled with the electric connector A in the opposite direction, the electric hole A can be smoothly inserted into the electric hole A on the module because the electric hole A and the electric connector A are spaced from the center by the same distance u as x, and the module can be assembled with the rear cover. When the electric hole A on the LED module is assembled with the electric connector B in a direction opposite to the direction, the electric connector B cannot be inserted into the electric hole A on the module because the distance between the electric hole A and the electric connector B from the center is different from u to y, and the LED module cannot be assembled with the rear cover.

It can be seen from the above that the assembly between the LED module and the rear cover 13 mainly achieves the fool-proof effect through the difference between the electrical connectors on the two sides and the distance between the electrical holes and the center. The assembly is smooth when the distance between the two sizes and the center is consistent, and the assembly cannot be carried out when the distance between the two sizes and the center is inconsistent.

The foolproof structure is completed by adopting the existing functional structures of the LED module and the rear cover without adding extra structures, has the functions of preventing the module from not working due to the fact that the LED module is reversely mounted ①, improving the assembly efficiency during production and assembly of the ② module, and completing assembly of the module only in the correct direction without distinguishing the assembly direction of the module by maintenance personnel during maintenance of ③ lamps.
