Abstract
The present invention provides a kind of LED spotlights of varifocal darkening, including shell and right-to-left to be sequentially arranged in the intracorporal electrochomeric glass of shell, transparent glass, lens board, LED light source board, screw motor；The LED light source board is connect with screw motor；Inner sidewall of the shell between transparent glass, lens board is equipped with reflective layer.The characteristics of optically focused modulated structure is simple, low in cost, energy saving, on the one hand utilizes LED itself adjusts the color of light, and the light and shade of light is on the other hand adjusted using electrochomeric glass, the range of darkening is greatly improved, greatly strengthens stage effect；Good in thermal property is fanned simultaneously.
Description
Technical field
The invention belongs to luminaire applications technical fields, are related to a kind of stage lighting, in particular to a kind of varifocal darkening
LED spotlight.
Background technique
LED has the advantages that such as low in energy consumption, the service life is long, generates heat less, response is fast and space-efficient, therefore LED is answered in illumination
It is widely used in.Spotlight is largely the lamp of direct-injection type at present, and periphery is aided with shot-light or diffusion lamp creates an atmosphere,
Special red-letter day needs more to become light color when increasing festive air, then to need replacing the spotlight of corresponding color effect, so
Not only waste of resource, not enough energy conservation and environmental protection.
Summary of the invention
Technical problem: in order to solve the defects of prior art, the present invention provides a kind of LED optically focused of varifocal darkening
Lamp.
Technical solution: the present invention provides a kind of LED spotlight of varifocal darkening, including shell and right-to-left according to
The secondary electrochomeric glass being set in the housing, transparent glass, lens board, LED light source board, screw motor；The LED light source board with
Screw motor connection；Inner sidewall of the shell between transparent glass, lens board is equipped with reflective layer.
As an improvement, further including fan 8, the fan is set on the left of screw motor；The shell is located at lens board, LED
Air hole is equipped in side wall between light source；The LED light source board is equipped with through-hole；The shell left end is air inlet.
The utility model has the advantages that the LED optically focused modulated structure of the varifocal darkening is simple, low in cost, on the one hand energy saving is utilized
The characteristics of LED itself, adjusts the color of light, and the light and shade of light is on the other hand adjusted using electrochomeric glass, is greatly improved darkening
Range, greatly strengthen stage effect；Good in thermal property is fanned simultaneously.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the LED spotlight of varifocal darkening.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The LED spotlight of varifocal darkening, is shown in Fig. 1, is sequentially arranged in the electricity in shell 1 including shell 1 and right-to-left
Cause photo chromic glass 2, transparent glass 3, lens board 4, LED light source board 5, screw motor 6；LED light source board 5 is connect with screw motor 6；
Inner sidewall of the shell 1 between transparent glass 3, lens board 4 is equipped with reflective layer.
It further include fan 8, fan is set to 6 left side of screw motor；Side wall of the shell 1 between lens board 4, LED light source 5
It is interior to be equipped with air hole；5 plate of LED light source is equipped with through-hole；1 left end of shell is air inlet.
