The present disclosure provides a light source module and a lighting device using the same. The light source module includes: a support member, to be disposed on a lighting device and provided with a first positioning portion; a light source mounting member, having a second positioning portion to be jointed with the first positioning portion through shape matching, where the light source mounting member has a bearing surface for disposing a light source electronic component; and a lens member, covering the bearing surface and connected to the support member in a positioned manner.

The present disclosure provides implementations of a track lighting adapter to couple a luminaire to a lighting track. The track lighting adapter includes a luminaire adapter to couple to the luminaire, and a track adapter to couple to the lighting track. The track adapter is selectively removable from the luminaire adapter.

A luminaire includes a lamp barrel having a light source detachably connected with a lens assembly. The lens assembly includes a lens barrel detachably connected with the lamp barrel and a focusing member on the lens barrel. An adjusting assembly includes a rotatable focusing ring, a lens fixing ring and a lens. The focusing ring includes a spiral groove on an inner surface. The lens fixing ring includes a projected rail on an outer surface. The lens barrel includes a bar shaped through hole extending along an axial direction. The projected rail passes through the bar shaped through hole and is mated with the spiral groove by clearance fit. Rotation of the focusing ring acts on the projected rail through the spiral groove and drives the lens fixing ring and the lens forward and backward in the lens barrel to adjust a distance between the lens and the light source.

A LED Light device for house or stores or business application having built-in camera unit is powered by AC or-and DC power source for a lamp-holder, LED bulb, security light, flashlight, car torch light, garden, entrance door light or other indoor or outdoor LED light device connected to power source by (1) prongs or (2) male-base has conductive piece can be inserted into a female receiving-piece which connect with power source or (3) wired or AC-plug wires. The device has built-in camera-system has plurality functions to make different products and functions. The LED light device has at least one of (a) camera or DV (digital video) to take minimum MP4 or 4K image or photos, (b) digital data memory kits or cloud storage station, (c) wireless connection kits, Bluetooth or USB set for download function, (d) MCU or CPU or IC with circuit with desired motion sensor/moving detector(s)/other sensor, (e) camera-assembly for connecting Wi-Fi, Wi-Fi extend, or-and 3G/4G/5G network or even settle-lite channel, (f) system to transmit or-and receiving wireless signal, (g) APP or other platform incorporated with pre-programed or even AI (artificial intelligence) software has optional area-selections function to make screen-comparison or image comparison to operation pre-program or related device including but not limited to detect moving object(s), face recognition or personal identification or-and habit or-and crime comparison, purchase, (h) LED light source to offer sufficient brightness under dark environment for camera-assembly take color data, (i) other electric or mechanical parts & accessories, (j) has moving detector and software built-in to make comparison to judge the movement object of the preferred screen selected-areas; to get desired function(s) for the said LED light device.
