Description

MULTI-DIRECTIONAL ADJUSTABLE SOLAR OUTDOOR PROJECTION LIGHT FIELD OF THE INVENTION

[0001] The present invention relates to a solar outdoor projection light, and more

particularly to a projection light capable of adjusting its lighting range, angle and sensing

direction.

BACKGROUND OF THE INVENTION

[0002] Outdoor LED sensor lights are commonly used in parking lots, home entrances,

private roadways, or garden paths and other environments. The sensor lights mainly use a

sensor, such as a light sensor or motion detection infrared sensors to detect surrounding

environmental conditions in order to achieve the effects of controlling the ON and OFF of the

LED, preventing people from forgetting to turn on and off the sensor light switch, and

providing a more power-saving and convenient operation and a warning function.

[0003] In general, an infrared sensor has a sensing angle and a sensing distance of a certain

range, and the sensing angle is about 100~180 degrees. When the sensor senses a person at

night or an approaching vehicle, the sensor light will activate the LED lighting; and when no

person or vehicle is detected, the sensor light will turn off the lighting. In order to ensure that

the sensor light can be illuminated normally in an area selected by users, builders need to

adjust the installation position repeatedly when installing the sensor light, and thus the

construction is time-consuming. In addition, the sensor light is fixed and its sensing angle

cannot be adjusted flexibly, and when the users change the selected area afterwards, it is

necessary to remove and reinstall the sensor light.

[0004] Furthermore, LED has the features of high light source directivity and relatively

limited lighting range, and thus different models of LEDs with adjustable lighting direction

available on the market are provided for the users to adjust the lighting direction of each LED lamp head on the sensor lamp and expand the lighting range of the LED lamp.

[0005] The inventor of the present invention has designed and developed a solar garden

light as disclosed in U.S. Pat. No. 10,488,002, which can project a light towards the front or

the rear, and adjust the focal length of the projected light with various lighting effects.

However, the functions of effectively sensing and controlling the lighting and flexibly

adjusting the lighting range are still limited. For example, when a user needs to project a light

towards the front, rear and surrounding region of the lamp at the same time, or at different

elevation/depression angles, the lighting range that the sensor light can expand is still limited

and unable to meet the user requirements. Overall speaking, the sensor lamp is limited by the

sensing angle and the lighting direction, so that the design of outdoor lighting is also limited.

overcome the aforementioned shortcomings and effectively expanded the function and scope

of applicability of the product.

[0006] In view of the aforementioned drawbacks, the inventor of the present invention

provides a multi-directional adjustable outdoor solar projection light to overcome the

drawbacks of the conventional projection light and expand the function and scope of

applicability of the product

SUMMARY OF THE INVENTION

[0007] Therefore, it is a primary objective of the present invention to provide a solar

outdoor projection light capable of adjusting its lighting range and angle, and sensing

direction and allowing users to have larger lighting range and wider sensing angle and

direction, (such as projecting a light with an angle towards the front and rear directions or

towards the up and down directions at the same time), and the installed outdoor projection

light can adjust its sensing direction as needed and improve the convenience of installation

and use; and/or to provide the public with a useful choice.

[0008] The present invention provides a multi-directional adjustable solar outdoor

projection light, comprising a support assembly capable of adjusting a support angle, a key light installed on a top of the support assembly and capable of projecting a light towards a front of the key light, and a solar power module disposed on a top of the key light, wherein the key light comprises two sides which each respectively comprises a pivotable fill light, the two fill lights deflectable up and down and pivotable through at least 180° relative to the key light to adjust angles of elevation and front and rear projection directions of the fill lights, in order to provide lighting angles different from that of the key light; and a sensor rotatably connected to the support assembly, the sensor rotatable through at least 180° axially relative to the support assembly to adjust a sensing direction for the front and rear projection directions.

[0009] Compared with the prior art, the multi-directional adjustable solar outdoor

projection light has the following advantages:

[0010] 1. The two fill lights can be deflected up and down relative to the key light, thereby

adjusting the angles of elevation and depression and the front and rear directions of the

projected light, providing a lighting angle different from the key light or even in the opposite

direction, and expanding the lighting range.

[0011] 2. The sensor can rotate 360 degrees relative to the axis of the support assembly to

adjust the sensing angle, so that the outdoor projection light can adjust the sensing direction as

needed after installation, improve the convenience of installation and use, and improve the

deficiencies of the conventional LED sensor lights that cannot adjust the sensing range

conveniently and needs repeated installation and removal for confirmation.
