A zoom optical system includes a light source and focus, zoom, and fixed lens groups. The light source illuminates an object in or adjacent to an object plane. The focus lens group has a first positive optical power and moves to focus an object. The focus lens group has four lenses of positive, positive, positive, and negative optical power. The zoom lens group has a negative optical power and moves relative to the object plane and the focus lens group to control a beam angle while the focus lens group remains fixed relative to the object plane. The zoom lens group comprises two negative power lenses. The fixed lens group has a second positive optical power, remains in a fixed position relative to the object plane, and projects an image of the object. The fixed lens group has three lenses, comprising negative, positive, and positive optical powers.

An LED lamp with a four-wire double-sided PCB includes a PCB, wherein the PCB is provided with a first LED luminous body and a second LED luminous body, respectively at the central regions of the obverse and reverse sides of the PCB to realize 360 light emission; the PCB is also sequentially provided with four electrodes around any one of the two central regions, wherein two electrodes are respectively configured to be connected with different signal terminals of the two LED luminous bodies; the remaining two electrodes are respectively configured to be connected with different power supply terminals of the two LED luminous bodies. The LED lamp provided by the present disclosure can emit light on both sides, and truly realize 360 light emission.

An image display device with an ambient light strip assembly includes a back plate and a light strip assembly. The light strip assembly includes a first light group disposed horizontally, a second light group disposed vertically, a first corner light group, and a second corner light group. The first corner light group and the second corner light group are located between the first light group and the second light group. The first corner light group includes more than two auxiliary light beads. One auxiliary light bead is adjacent to the second corner light group, the remaining auxiliary light beads are arranged in sequence toward the first edge, the vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than the vertical distance between the auxiliary light bead on the other side and the first edge.

A project light device comprises multiple light assemblies and at least one pivotable connecting assembly. The at least one pivotable connecting assembly is connected between two adjacent light assemblies. Each light assembly comprises a shell, and a light-emitting module and a light-concentrating structure that are mounted inside the shell. The light-concentrating structure concentrates light emitted from the light-emitting module to project light out of the shell. The at least one pivotable connecting assembly comprises a joint seat, a middle pivotable rod and a joint rod. The joint seat and the joint rod are respectively mounted at two adjacent light assemblies. The joint rod is pivotably mounted at the middle pivotable rod pivotably mounted at the joint seat. The two adjacent light assemblies are connected through the pivotable connecting assembly, thereby being pivotable relative to each other, so the light assemblies project lights to different directions.

A lighting apparatus includes a light source plate, a driver, an antenna base and an antenna module. The driver includes a wireless circuit. The antenna base unit includes a first plastic unit, a metal contact and a metal path. The antenna base is coupled to the light source plate. The metal contact is electrically coupled to the wireless circuit of the driver. The antenna module includes a metal antenna and a second plastic unit. The second plastic unit and the first plastic unit are two separate components. When the second plastic unit is coupled to the first plastic unit, the metal antenna is electrically coupled to the metal contact of the antenna base for receiving a wireless signal to the wireless circuit of the driver.

A light-emitting device of one embodiment of the present disclosure includes: a light source section including a surface light source; a light reflective film that covers a surface of the light source section and has one or more openings on a light outputting surface of the light source section; and a reflecting structure that is provided on side of the light outputting surface of the light source section and has one or more light reflecting surfaces around the one or more openings, the one or more light reflecting surfaces reflecting light outputted from the one or more openings in a predetermined direction.
