The present invention provides a method for constructing a universal LED bulb, a flange snap ring type LED bulb and a lamp. A heat conductive bracket (3) is used as the structure supporting main body to establish an optical engine core member. A thin-shelled lens snap ring (8) is used to support the optical engine core member in an auxiliary manner. An installation flange hole is provided to the lens snap ring (8), correspondingly to an installation flange hole of the heat conductive bracket (3), to surround and protect the heat conductive bracket (3). The optical engine core member is composed of the heat conductive bracket (3), an optical engine module (4), an inner snap ring (81) and a light distribution optical lens (7). An inner cover (6) is provided outside the optical engine module (4). An electric connector (11) is provided to the heat conductive bracket (3).

A thermal module and a projector using the same are provided. The thermal module comprises a heat sink and a base. The heat sink comprises a bottom, a plurality of fins, a cover, and a plurality of side walls. The fins are disposed on the bottom, and each of the fins comprises a reference plane and a plurality of protrusions, wherein adjacent two of the protrusions are convex toward opposite directions with respect to the reference plane, and rows of through holes are formed by adjacent two protrusions along a flowing direction. The cover is disposed on the fins. The side walls are disposed between the bottom and the cover and surrounding the fins, wherein a liquid is capable of flowing through the heat sink by entering the inlet and exiting by the outlet of the side walls or the cover. The bottom of the heat sink is disposed on the base.

An underwater diving light includes efficient cooling of LEDs and other internal electronics by heat transfer to ambient water. The water is in contact with a metallic face plate or puck that conducts heat via contiguous metal from an LED circuit board or LED face plate. Ambient water can enter the assembly to spaces between the face plate and an intermediary plate at the front of a housing to efficiently cool the LEDs and associated electronics. In a high-output form the light can emit 8000 lumens, and in this embodiment the battery is cooled by ambient water. The face plate or puck is interchangeable, for different lighting characteristics.

Disclosed is a laser-based device for use primarily for laser light effects. The laser device comprises multiple red, green, and blue lasers. Each laser has a lens to collimate and focus each individual beam. The lasers are aligned such that each laser shares a common output axis. The intensity of each laser is adjustable thereby allowing the overall output color of the device to change. The overall output has over 16 million colors. Each laser-based device has a gimbal-like system to allow the devices change theft orientation. A remote control system allows for the control and synchronization of multiple devices. Multiple devices may connect to the remote control system using cables, wireless transceivers, or both. Multiple devices may be located in close proximity to create a more powerful overall output beam. The remote control system allows for viewer interaction through an application installed onto a personal communication device.

Generally, the present disclosure provides for a light engine, in particular a rack-mounted light engine that can be used in a lighting system. The rack mounted light engine can be positioned in an electronics component rack such a light distribution system using hollow light ducts may distribute the light over a large area, such as a data center. Such a light distribution can use a generated light more efficiently by directing the light to the fronts or backs of the electronics cabinet, rather than for general room illumination.
