The third face (1063) along with the first and the second face (1062) apply tension on the rim (104) at the plurality of second flanges (1042) thereby fixing the position of the rim (104) on the one or more bracket rim mountings (106) using cantilever snap fit mechanism.
Furthermore, as shown in figure 5 and explained in figure 5B-B, the plurality of ribs (1022) provided on the housing (102) configured to latch on the plurality of first flanges (1040) of the rim (104). In an alternate or additional embodiment, the plurality of ribs (1022) may be bolted or screwed on the plurality of first flanges (1040) of the rim (104). In another embodiment, the plurality of ribs (1022) may be fitted on the plurality of first flanges (1040) using a snap fit mechanism.
The present invention provides a number of advantages. Firstly, less space required for bracket rim mounting fixing during assembly. There is a reduced damping tap. Further, the cost of the lamp is reduced. Time of assembly is reduced due to less complicated and easy design. Easy assembly results in reduced operator fatigue. Further, Strength of the assembly is more than that of spring fixing. Furthermore, the compact size and less power consumption of the present invention make it a cost-effective solution to the problems of the prior art.
