Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
The level and smooth travel mechanism of one as shown in Figures 1 to 3, comprise base plate 1, LED lamp panel 2, lens subassembly 3, driving mechanism 4 and guiding mechanism 5, LED lamp panel 2 is fixed on base plate 1 surface, driving mechanism 4 is installed on base plate 1, this driving mechanism 4 has the output for driving lens subassembly 3 to move along the direction away from LED lamp panel 2 and close LED lamp panel 2, and this output is connected with lens subassembly 3; Guiding mechanism 5 comprises the first fixture 51, second fixture 52, fixed axis 53 and at least two movable axis 54, first fixture 51 is affixed with lens subassembly 3, second fixture 52 is affixed with base plate 1, one end of fixed axis 53 be plugged in the second fixture 52 and with the second fixture 52 tight fit, the other end and first fixture 51 of fixed axis 53 are slidably matched; One end of movable axis 54 be plugged in the second fixture 52 and with the second fixture 52 matched in clearance, the other end and first fixture 51 of movable axis 54 are slidably matched.
LED lamp panel 2 electric after will be luminous through the LED chip of its dispersion distribution, after reflect through lens subassembly 3 again and form hot spot, and lens subassembly 3 is away from LED lamp panel 2 or in the moving process of LED lamp panel 2, and hot spot is then corresponding to be expanded or reduces.By the setting that one end of movable axis 54 coordinates with the second fixture 52 free gap, when lens subassembly 3 can be made to move back and forth under driving mechanism 4 orders about, movable axis 54 can adjust respective angle of inclination automatically, to form the smooth and easy level and smooth guiding to lens subassembly 3 in conjunction with fixed axis 53 better, both can prevent stuck, preventing lens output facula size through lens subassembly expanding or the saltus step reduced in process, the quality of fit requirement of guiding mechanism 5 can be reduced again, reduce costs.
