Abstract: Disclosed are an elastic assembly and a down lamp. The down lamp includes a lamp body and an elastic assembly. The elastic assembly includes a limiting assembly and a spring. The limiting assembly is provided with a rotating cavity. The fixing end of the spring is rotatably embedded in the rotating cavity, so that a flip angle of a movable end of the spring ranges from 0° to 90°. The present disclosure can enlarge the adjustable angle of the spring and reduce the assembly difficulty of the down lamp.

Abstract: A filament lamp includes a plastic housing, a transfer switch, and a laterally rotary structure. The transfer switch is disposed in the plastic housing, an outer wall of the plastic housing is provided with an opening, the laterally rotary structure is rotatably disposed on the outer wall of the plastic housing, an inner side, close to the plastic housing, of the laterally rotary structure extends to form a drive connecting structure, and the drive connecting structure passes through the opening to be connected with the transfer switch in a transmission way. With the design of the laterally rotary structure, when gears are adjusted by a user, the transfer switch is operated by the drive connecting structure only by rotating the laterally rotary structure on the outer wall of the plastic housing, so as to switch the gears.

Abstract: A lateral light emitting atmospheric downlight includes a light body, a first light source module, a second light source module and a light guide module. An upper end and a lower end of the light body are respectively provided with a communicating opening, the first light source module is arranged around an inner wall of the light body, the light guide module is arranged in the light body, and a light exiting surface of the first light source module is opposite to the light guide module; the second light source module is arranged around an outer wall of the light body, and one side, away from the light body, of the second light source module emits light. With the design above, multi-directional light emission of the downlight is achieved.

Abstract: Disclosed is a night downlight, including a plastic case, a first lamp bead, a second lamp bead and a light guide ring. One end of the plastic case is provided with a light outlet, and the bottom of the plastic case is provided with the first lamp bead and the second lamp bead, the first lamp bead is arranged at the center of the bottom of the plastic case, the light guide ring includes a light guide inner ring and a light guide surface ring, the light guide inner ring is sleeved in the plastic case, one end of the light guide inner ring abuts against the second lamp bead, and the light guide surface ring is connected with the light guide inner ring and protrudes from the light outlet. The light guide area of the night downlight is larger, which can meet the needs of night lighting.

Abstract: Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.

Abstract: A LED lamp and a manufacturing method thereof are disclosed. At least one blue LED chip can be used as an excitation light source. A number of red LED chips are arranged around the blue LED chip. The blue LED chip and red chips are covered with a packaging material with phosphor. The intensity of red light can be adjusted by a control circuit. Thus, the white LED lamps with high efficacy and high color rendering at different color temperatures can be achieved.

Abstract: An electronic ballast includes a rectifier and filter circuit, a DC/AC inverter circuit and a resonant circuit. An input of the rectifier and filter circuit is connected to an outside power supply, its output is connected to the inputs of DC/AC inverter circuit, an output of the DC/AC inverter circuit is connected to inputs of the resonant circuit, and an output of the resonant circuit is connected to a lamp. In addition, a feedback driver circuit and a filament current loop are connected to the lamp at its input. An input of the feedback driver circuit is connected to the filament current loop, and its output is connected to the control terminal of the DC/AC inverter circuit. Electrical signals of the filament current loop control the DC/AC inverter circuit drive the resonant circuit through the feedback driver circuit. The filament capacitor is disconnected from the lamp when the filament is broken.
