Surface in rotation axiss deflection.So as to the light beam in reflector be projected as much as possible by lens, by around position
Rotation axiss deflection lens in the surface of the optical axis perpendicular to the light source, can adjust difference of the lens relative to optical axis
Orientation, and then realize the adjustment of irradiation area.
Preferably, the reflector rotates empty to limit the closing for accommodating the light source jointly relative to the lens
Chamber.So, will ensure that the light beam that light source sends will not be leaked out from closed cavity, so as to further increase light efficiency.
Preferably, the reflector is the hemisphere that light direction is opened, and the rotation axiss of the lens are the hemisphere
The diameter of body.
A preferred implementation of the invention, the rotatable optics has gudgeon, the reflection cup
There is the perforate for accommodating the gudgeon positioned at the edge of the reflector, so as to lens utilize gudgeon propping up in perforate
Support, is rotated.
Preferably, the illuminating angle adjusting device also include regulating part, the regulating part through the perforate with it is described
Link together gudgeon anti-torsion.So as to the regulation by realizing the rotation for lens for the regulation of regulating part.
Preferably, reflector also includes the boss of the edge for being located at reflector, and perforate is opened in the boss.
A preferred version of the invention, rotatable optics also include be located at lens around as sidewall region
The reflector space in domain.The reflector space can auxiliarily adjust irradiation area, so as to increase irradiated region using reflector space
The motility of the adjustment in domain.
The invention further relates to a kind of illuminator, a kind of more specifically shot-light.Preferably, the shot-light is LED spotlight.It is excellent
Choosing, the illuminator of the present invention also includes the circuit board of the placement light source, and the pedestal is placed on the circuit board.This
Invention further relates to a kind of display utensil, including the illuminator.
Illuminating angle adjusting device of the invention can be realized just realizing lighting area only by relay lens
The regulation in domain, has the advantages that prominent easy to adjust.
It should be understood that the general description of the above and the following detailed description are all enumerated and illustrative, it is therefore an objective to
In order to provide further instruction to claimed invention.
