Description
Technical field
The present invention relates to a kind of lamps, more particularly to a kind of device that can change light irradiation direction.
Background technique
In actual normal lighting, the direction of illumination of lamp is either to dissipate to all the winds or is to be limited by lampshade admittedly
Determine in a certain direction, but generally requires to change the direction irradiated in reality, for example navigation light is gone to some
Orientation is guided to ship with course, indoor wall lamp needs to be pointed into ceiling or certain to generate the effect of shot-light or focusing for another example
These demands for needing to change the direction of illumination of light of fruit, etc. require the simple and practical structure of one kind and are applied and realize.
It is learnt through retrieval and inquisition, the technical solution of two sections of patents connects with the technology of the present invention and compared with realizing above-mentioned requirement below
Closely, 1 is：A kind of device that can change LED spotlight irradiation light direction of CN20156387512.8-；2 are：CN1030332841A-
A kind of lamp capable of being mounted at multiple angles and lamp mounting support thereof.This two patented technologies all do the direction of illumination for solving to change lamp
Certain contribution is gone out, it was also proposed that corresponding feasible technical solution.But as a kind of indexing control convenient manually
Change the scheme of light direction of illumination, above-mentioned two kinds of technical solutions do not propose.Patent 1 is by two stepper motors first
The purpose to realize the direction of illumination for changing light is acted, so makes mechanism that can become complicated, two will increase some costs,
Furthermore the installation environment and automatically controlled reliability to motor are proposed higher requirement；Secondly patent 2 is using a kind of polygonal
The mounting means of degree come realize change light direction of illumination purpose, to change a direction often in this way it is necessary to convert a position
Set installation lamp body, one it is cumbersome it is dangerous be not easy to change direction of illumination at any time, two carry out the change of 360 degrees omnidirection to be realized
Change place installation is also relatively difficult, is difficult to realize, furthermore also hampers the beauty of illumination and lamps and lanterns in lamp cap position arrangement bracket.
Summary of the invention
For illuminator in routine use and installation process, the direction of irradiation is relatively more fixed, and changes direction of illumination
Lack a kind of effectively simple mechanism again often come the problem of realization；The practical simple non-electrical flowing mode of one kind is considered as to give
To solve.
Consider that present invention employs a kind of manual indexing mechanisms to be connected between lamppost and lamp base based on above-mentioned, Ke Yili
