Tracking lighting fixtures

The present invention discloses a lighting fixture, in particular a reflective tracking lighting fixture capable of automatically adjusting a light source to be traced after being reflected or directed.

In the past, the lamps appearing in the lighting market are passively adjusting the lighting area to the mainstream. Whether it is a table lamp, a standing lamp or a wall lamp, once the lamp is positioned, the illumination direction is adjusted backward and the illumination area is manually determined according to the user's needs. Adjustment.

Although the above-mentioned manual adjustment has been in operation for a long time, it has been found that it is often difficult for a user to adjust the preferred illumination angle. In particular, it is difficult to manually adjust the illumination area of the desk lamp, the standing lamp or the wall lamp at any time and with the user's replacement, or It is difficult to manually adjust the illumination area of table lamps, standing lamps or wall lamps using scientific illumination data. Therefore, it is often the case that young children and elderly people use the lighting fixtures to deepen the parallax of the eyes or cause the eyes to develop lesions.

In view of this, a kind of lamp that automatically adjusts the light source tracking user is beginning to appear on the market. Generally speaking, the existing lamp source tracking user technology utilizes a Y-axis servo motor, a Z-axis servo motor and an infrared sensing component. It is used to sense the infrared rays emitted by the user's one-piece set, and the infrared sensing component can be used to detect the position of the pen cover, and then drive the Y-axis servo motor and the Z-axis servo motor to rotate the light source on the lamp and change the elevation angle; thereby achieving active tracking The user performs the purpose of lighting.

Although the above-mentioned conventional active tracking illumination technology can achieve automatic adjustment of the light source tracking user, there are still many shortcomings to be improved:

First, the aforementioned conventional design is detected by using an infrared sensing element. The position of the pen holder, and then drive the Y-axis servo motor and the Z-axis servo motor to rotate the light source on the lamp and change the elevation angle. However, in fact, the light source actually tracks the pen cover of the user's hand, but the light source actually tracks the user itself, resulting in If the user is working outside of writing, the prior art cannot actively adjust to the illumination tracking.

Second, according to the height of the user's body, in fact, different users need different lighting areas for writing, and the lighting area does not simply follow the user's hand position to meet the demand.

There is also a luminaire that actively adjusts the light source to track the user. The prior art further utilizes infrared sensing to sense the distance and direction of the human body, and then drives a Y-axis servo motor and a Z-axis servo motor to rotate the light source on the luminaire and change the elevation angle. However, although the second conventional design actually actively follows the user's body for adjustment, it still cannot be adjusted according to the height of the human body. Therefore, the second conventional technique still cannot change the illumination area for the writing needs of different body users.
