Abstract

A lighting device has an upper casing 1, a middle casing 2, a lower casing 4, and a sensor (20, fig 1). The middle casing 2 has threads to join the upper 1 and lower 4 casings. Light emitting diodes placed in the middle casing surround the sensor (20, fig 1). The lower casing 4 is joined to a power socket. The sensor (20, fig 1) has a cylindrical casing 203 with a spherical top end threaded through a ring 202, which form a spherical shape. The sensor (20, fig 1) is rotatable in a spherical concave 201 on the middle casing 2, so that it could be easily turned to point to a desired direction. Ventilation holes (23, fig 1) and slots (24, fig 1) are provided.

Description

TITLE: LIGHTING DEVICE WITH SENSOR
(a) Technical Field of the Invention
The present invention generally relates to lighting devices, and especially relates to a lighting device inteating a sensor assembly whose direction could be easily and conveniently adjusted.
(b) Description of the Prior Art
Various sensor devices have been widely applied in daily lives. One common application is to use a sensor device to turn on/off a lighting device or to activate/deactivate a video survefflance device so as to achieve efficient energy or resource usage.
Regardless its type and quality, a sensor usually has a specffic sensing direction and a specific coverage. As such, the sensor has to be manually adjusted to aim at the desired direction and coverage or some automatic adjustment means is required so that the sensor can detect the entrance or exit of an object into or out of the coverage. Therefore, the sensor is usually mounted on some pivot and could be adjusted by some lever. However, with these additional means, the sensor becomes bulky and the adjustable rage is usually limited by the pivot or lever. Blind spots where the sensor cannot effectively perform detection are therefore often inevitable.
SUMMARY OF THE INVENTION
Accordingly, a novel lighting device with an integrated sensor assembly is provided herein to obviate the foregoing shortcomings of the prior arts.
The lighting device mainly contains an upper casing, a middle casing, a circuit board, a lower casing, and a sensor assembly. The middle casing has a number through hoTes around a top circumference and a number of ventilation slots around a middTe circumference. Circumferential threads are provided between the through holes and the ventilation slots, and beneath the ventilation slots. A number of light emitting diodes (LEDs) are configured on a top surface and a bottom surface of a top side of the middle casing, and the sensor assembly is configured among the LEDs. A bottom side of the lower casing is joined to a power socket and, inside the lower casing, the circuit board is configured and connected to the LEDs and the sensor assembl!y. The sensor assembly contains a cylindrical casing with a spherical! top end and a ring. The cylindrical casing is threaded through the ring, jointTy constituting a substantially spherical shape. The sensor assembly is then rotatably configured in a spherical concave on the top side of the middle casing.
The sensor assembly could be easily turned to point to a desired coverage area by manually twisting the ring. The sensor assembly is specffically configured into a spherical! shape and therefore its rotational! angl!e is not limited by any pivot or Tever as in the prior arts. In addition, as no lever or pivot is used, the sensor assembly could have a smaller dimension and could be more flexibly applied to various lighting devices. To achieve even easier assembly and lower production cost, the upper casing could actually be replaced by an enlarged casing.
The foregoing objectives and summary provide only a brief introduction to the present invention. To frilly appreciate these and other objects of the present invention as well as the invention itself, all of which wifi become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specffication and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of ifiustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the foHowirig description provides a convenient ifiustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As illustrated in FIGS. 1 to 5, a lighting device in accordance with an embodiment of the present invention mainly contains an upper casing 1, a middle casing 2, a circuit board 3, a lower casing 4, and a sensor assembly 20.
As exhibited in FIGS. 1 and 2, the middle casing 2 has a tubular shape with a number through hoks 23 around a top circumference and a number of axially-oriented ventilation s'ots 24 around a middTe circumference of the middle casing 2. Circumferential threads (not numbered) are provided between the through holes 23 and the ventilation slots 24, and beneath the ventilation slots 24, for joining with the upper and lower casings 1 and 4, respectively. A number of light emitting diodes (LEDs) 21 are configured on a top surface and a bottom surface of a top side of the middle casing 2, surrounding the sensor assemNy 20. A bottom side of the lower casing 4 is joined to a power socket (not shown) and, inside the lower casing 4, the circuit board 3 is configured and connected to the LEDs 21 and a sensor inside the sensor assembly 20. The sensor assembly 20 contains a cylindrical casing 203 with a spherical top end and a ring 202. The cylindrical casing 203 is threaded through the ring 32, jointly constituting a substantially spherical shape. The sensor assembly 20 is then rotatably configured in a spherical concave 201 on the top side of the middle casing 2 and is further confrned by a circular center openhg of an upper cover 11 housed in the upper casing 1.Alternatively, the concave 201 and the upper cover 11 could be an integral part of the upper casing 1 so that the sensor assembly 20 is configured directly on the upper casing 1, as shown in FIG 6.
As shown in FIGS. 3 to 5, the sensor assembly 20 is rotatably positioned in the spherical concave 201 and the upper cover 11 is positioned higher than the center of the sensor assembly 20 SO that the sensor assembly 20 is reliably confrned between the spherical concave 201 and the upper cover 11. As described and illustrated, the sensor assembly 20 (and therefore the sensor inside) could be easily turned to point to a desired coverage area by manually twisting the ring 202. When a person or some object has entered the coverage area, the sensor inside the sensor assembly 20 would detect the object and turn on the LEDs 21 of the lighting device. When the object leaves the coverage area, the sensor could turn off the LEDs 21 so as to save energy consumption.
Please note that the sensor assembly 20 is specffically configured into a spherical shape and therefore its rotational angle is not limited by any pivot or lever as in the prior arts. fri addition, as no lever or pivot is used, the sensor assembly 20 could have a smaller dimension and could be more flexibly applied to various lighting devices.
FIGS. 7-10 provide various equivalent configurations of the sensor assembly 20 according to alternative embodiments of the present invention.
As further shown in FIG 11, in yet another embodiment of the present invention, the upper casing 1 could actually be replaced by an enlarged casing 203 to achieve even easier assembly and lower production cost. In this embodiment, there is no ring 202, and the cylindrical casing 203 would be fixed and is not abTe to turn.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modffications, substitutions and changes in the forms and details of the device ifiustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
