Description

Variable-focus LED control device based on guide rail Technical Field The utility model relates to the field of focusing control, in particular to a variable-focus LED control device based on a guide rail. Background The variable-focus LED lamp is a lamp commonly used at present, because the LED lamp group needs to be moved during zooming, tools capable of accurately adjusting the position of the LED lamp group are needed to be used in the variable-focus LED lamp at present, the tools commonly used for adjusting the position of the LED lamp group at present are screw guide rail components, the structure of the screw guide rail components commonly used at present is as shown in patent publication CN104596384B, the screw guide rail device shown by the structure is stable in operation and high in reliability, but the screw guide rail device shown by the structure has a problem when being applied to the variable-focus LED lamp, because the way that the screw guide rail device is used for measuring the position of a sliding block is laser ranging or infrared ranging, the two ranging essence are based on reflection ranging, the screw guide rail of the structure can not be used for stopping LED lamp light, and the problem that the ranging equipment can not accurately range due to interference caused by LED lamp light can occur during ranging. Disclosure of utility model According to the variable-focus LED control device based on the guide rail, the LED lamp group and the spiral matching block are respectively arranged on two sides of the mounting plate, the distance measuring probe is arranged on one side of the mounting plate and used for measuring the distance between the second support plate and the spiral matching block, the influence of light rays of the LED lamp group in the measuring process is avoided, and the measurement is relatively more reliable. The technical scheme adopted by the utility model is as follows: The utility model provides a variable focus LED controlling means based on guide rail, includes bottom plate, first backup pad, second backup pad, first guide rail, second guide rail and screw rod, first backup pad and second backup pad all set up in on the bottom plate, the both ends of first guide rail are in the same place with first backup pad and second backup pad fixed fit respectively, the both ends of second guide rail are in the same place with first backup pad and second backup pad fixed fit respectively, the both ends of screw rod are in the same place with first backup pad and second backup pad normal running fit respectively, still include mounting panel, first cooperation slider, second cooperation slider and spiral cooperation piece all set up in on the mounting panel, first cooperation slider through self through-hole with first guide rail sliding fit together, second cooperation slider through self through-hole with second guide rail sliding fit together, spiral cooperation piece with the screw rod cooperation together, the range finding probe sets up in first backup pad or second backup pad, and one side that is located the mounting panel is used for the mounting panel of LED lamp of one side of range finding.
