Description

A kind of adjustable eccentric shot-light

Technical field

The utility model is related to technical fields of lighting fixtures, more particularly to a kind of adjustable eccentric shot-light.

Background technology

LED lamp bead centralized arrangement is facilitated the design of secondary optics by COB, is kept the hot spot of lamps and lanterns more perfect, is facilitated lamps and lanterns It makes, COB shot-lights are wanted and secondary optics, generally have Lamp cup, lens to match, and secondary optics determine the light extraction of LED lamp Angle, this angle correspond to photographed object, determine according to appropriate level, sometimes photographed object may require that variation, thus need Different size of hot spot is wanted, in general, the hot spot of Lamp cup and lens is build-in attribute, once molding cannot change, and it is existing Angle adjustable shot-light solve the variation of light-emitting angle by way of the variation of lens distance light source luminescent face distance, when lens bottom When face paste close to sources light-emitting surface, light-emitting angle is big；When lens base is far from light source luminescent face, light-emitting angle is small, The size of light-emitting angle can be adjusted with distance change, but causes the loss of light efficiency, when light-emitting angle is big, light source Light-emitting surface and lens fitting are closer, and the light that light source is sent out directly impinges upon on lens, and the light efficiency of lamps and lanterns is similar with not dimming generally, than It is higher；When be adjusted to light-emitting angle it is small when, have certain distance between light source luminescent face and lens, the light that light source is sent out only part is thoroughly Lens are crossed, lamps and lanterns entirety light efficiency is caused to decline, and light efficiency degrades seriously, cannot protrude photographed object, it is meant that shot-light loses meaning, So that being had some limitations when use.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-4, a kind of adjustable eccentric shot-light, including radiating fin 1,1 side of the radiating fin are equipped with fixed Position pin 2,2 side of the positioning pin are equipped with light source 3, and holder 4, the holder 4 and the radiating fin are connected on the light source 3 1 phase is fixedly connected, and 3 side of the light source is equipped with the first lens 5, and first lens 5, which is equipped with, matches the positioning pin 2 Pin hole 6, and first lens 5 be equipped with several first open-works 7,5 phase of the first lens is far from the light source 3 one Side is equipped with the second lens 8, and second lens 8 is equipped with several second open-works 9 for matching several first open-works 7, Wherein, if dry lens 10 is equipped between the first lens 5 and the second lens 8, before 8 side of the second lens is equipped with Ring 11, the front ring 11 is interior to be equipped with loophole 12, and 12 side of the loophole is equipped with observation port 13, and is located in the front ring 11 13 side of the observation port is equipped with positive stop strip 14.

In the present embodiment, groove is equipped in the holder 4, the light source 3 is connected in the groove, and the holder 4 It is fixedly connected with 1 phase of the radiating fin by screw；First open-work 7, second open-work 9 and lens 10 are respectively three Group, and 8 side of the second lens is equipped with logo slot；Location hole, second lens are equipped in first lens 5 8 phases are equipped with several positioning columns close to 5 side of the first lens, and the location hole is adapted with the positioning column.

In the present embodiment, 3 bias of light source is affixed at radiating fin 1, and radiating fin 1 has the hole position of fixing bracket 4, so energy It enough determines 3 position of light source, heat-conducting silicone grease is smeared between light source 3 and radiating fin 1,4 fixed light source of holder is used on light source 3, positions, and And ensureing 3 back side of light source and radiating fin 1 is smooth is close to, the link pin hole 6 of positioning pin 2, lens 10 be free to rotate, the phase Between, each lens 10 can effectively coordinate with light source 3.There is front ring that it is made to be fixed with radiating fin 1 on second lens 8, and And in use, see lens 10 rotate how many angle according to observation port 13, side thumb wheel adjusts lens 10 and rotates, and is rotating to appropriate Behind angle position, positive stop strip 14 makes lens 10 realize limited fixation with front ring 11, prevents lens 10 free in no external force Rotation, in addition, after choosing angle, you can use of turning on light needs to adjust again, turn off the light, stirs positive stop strip 14.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
