An LED high bay light comprises a plurality of LED illuminant engines arranged abreast and alternately; each of the LED illuminant engine comprises an LED strip-shaped illuminant and an optical lens set covering the LED strip-shaped illuminant; the optical lens set comprises a plurality of strip-shaped optical lenses arranged conterminously; and two adjacent strip-shaped optical lenses are connected to each other through a mutual cooperation of the stepped spigots arranged oppositely. Each illuminant engine thereof adopts a structure of strip-shaped optical lens set with multiple sections, greatly reducing the difficulty in making molds and the cost for manufacturing parts.

An assembling mechanism for LED downlight includes a cylindrical body, at least one spring fixed on the cylindrical body, and a cover assembled on the at least one spring. Each of the at least one spring includes a fixing portion, a reed extending from the fixing portion along a rotation direction of the cylindrical body, and a catching portion disposed on the reed. The catching portion extends along the radial direction of the cylindrical body. The cover includes at least one clamping gap. Each of the at least one clamping gap includes an open provided along the rotation direction of the cylindrical body. The catching portion is inserted into the clamping gap from the opening by rotating the cover.

A light-emitting arrangement including an optical member and a light-transmissive shield member secured with respect to the optical member at least partially defines a light-fixture exterior and having a back side facing a circuit board and receiving a gasket which encircles the circuit board to provide water seal thereabout. The gasket had a pair of spaced apart outwardly-extending lateral fingers engaging lateral sides of a recess formed by the optical-member back side, and at least one inner finger extending into the recess offset from the recess lateral sides. A peripheral wall extends from the optical-member back side outwardly around the gasket and engaging an emitter-supporting to minimize water ingress toward the gasket. An opaque shield is disposed along at least a portion of a perimeter of the optical member and configured and dimensioned to minimize or block distribution of light in at least one direction opposite the direction of the primary illumination.

A sealing process of LED modules, comprising: (1) a waterproof wire goes through a wire-through hole of a heat sink to be connected with a positive-negative solder joints on a PCB board, wherein the positive-negative solder joint and the position that the waterproof wire going through are subjected to glue sealing treatment, and a waterproof sealing process is operated between the waterproof wire and the wire-through hole; (2) fix the PCB board on the heat sink; (3) place one sealing ring into one of the grooves; (4) apply evenly a ring of liquid silica gel along the other groove of the lens set and the amount of the liquid silica gel is limited to completely sticking the solid silica gel sealing ring; (5) the heat sink installed with the PCB board and the waterproof wire as processed in step (2) is inversely buckled on the lens set which is set with the solid silica gel ring and the liquid silica gel as processed in step (4), so as to fix the heat sink entirety and the lens set. At least two waterproof sealing rings are used for completely isolating an LED chip from the outside so as to prevent all water vapor or other harmful gases from corroding the chip and the PCB, and the sealing rings are firmer when being compared with thin film sealing; the service life is longer and the guarantees to the sealing performance between the lens set and the heat radiation frame are realized.

Provided is an electronic fountain candle, comprising a transparent or semitransparent outer cylinder (9), a battery compartment, a flow-guiding cover (10), an LED/water pump assembly (4), and a control board (3). The outer cylinder (9) is a hollow tube body. The battery compartment is an inverted cup-shaped body, the opening of the cup facing down, the bottom of the cup being on the top, and the cup-shaped body being sleeved inside the outer cylinder (9). A water storage chamber is located at the interior wall of the outer cylinder (9), above the bottom of the battery compartment cup. The LED/water pump assembly (4) is mounted inside the water storage chamber, and comprises: being equipped with an LED-PCB board (42) for an LED, as well as a water pump (43) and a water drainage pipe (41). The LED-PCB board (42) is waterproofed, and the water outlet of the water pump (43) is connected to the water drainage pipe (41). The flow-guiding cover (10) is provided with a flow-guiding hole, and the water drainage pipe (41) is in communication with the flow-guiding hole. The peripheral edge of the flow-guiding cover (10) is lower than the upper end face of the outer cylinder (9), and there is a gap, used for draining water, between the flow-guiding cover (10) and the inner wall of the outer cylinder (9). The control board (3) is mounted inside the battery compartment, and the LED/water pump assembly (4) is electrically connected to the control board (3). The LED of the electronic fountain candle simulates the weak light of a conventional lamp, while the circulation of water simulates the sound of flowing water in a natural environment, creating a natural and tranquil ambiance.
