A lighting system for a vertical garden includes at least one light ring including a central hub member configured to be removably mounted to the vertical garden, an outer ring member, and a plurality of spoke members extending radially between the central hub member and the outer ring member, a plurality of light sources supported in the outer ring member, and a drive circuit for the plurality of light sources, a power supply, and at least one power connector connected between the drive circuit and the power supply.

A lamp base includes a housing for at least partial accommodation of a carrier for a light source. Two mutually-opposing guide rails are provided in the housing for the form-fitted insertion of the carrier. The technology is particularly applicable to carriers with LEDs as light sources and addresses problems with adhesive or soldered attachment of the light source carrier.

When viewed in parallel to a central axis (C1), three LED substrates (4) form an equilateral triangle (T) that surrounds the central axis (C1) and are disposed equidistantly with respect to the central axis (C1). When viewed in parallel to the central axis (C1), LEDs (8) are disposed on an outer surface (4a) of each LED substrate (4) at least one each at each of a pair of placement positions (Q1) at both sides sandwiching a reference normal (BN) being a normal to the outer surface (4a) and passing through the central axis (C1). The LEDs (8) each have an optical axis (8a) orthogonal to the outer surface (4a). When viewed in parallel to the central axis (C1), radiated lights from the LEDs (8) at the pair of placement positions (Q1) of each LED substrate (4) are, by an optical system (K), converted to and emitted as emitted parallel lights (RPL) that are respectively parallel to a pair of light emission reference lines (RB) passing through the central axis (C1) at both sides sandwiching the reference normal (BN) and respectively contain the corresponding light emission reference lines (RB).

A light apparatus for generating a mixed light output. The light apparatus includes multiple LED modules. Each LED module includes multiple LED regions. The multiple LED regions cover a single LED chip. The multiple LED regions share the same package for emitting lights with different optical characteristics.

A vehicle lamp comprises a light irradiation unit including a light source and a board on which the light source is installed, a base member including a first surface for mounting the light irradiation unit and a second surface adjacent to the first surface, a connection terminal arranged on the second surface and extending and protruding in a direction of the first surface, and a coupling member arranged on the board and electrically connected with the light source. The connection terminal is inserted into the coupling member when the board is mounted on the first surface.

A diffuser for a hair dryer includes a diffusing case, a guide frame provided inside the diffusing case to guide a flow of gas introduced into the diffusing case, a light irradiator provided inside the diffusing case and in front of the guide frame to irradiate light toward a front side of the diffusing case, and a discharge cover provided at the front side of the diffusing case. The discharge cover includes a gas discharge hole to discharge the gas inside the diffusing case to outside. The discharge cover includes a plurality of massage protrusions to press a target located in front of the discharge cover.

The present invention discloses a light emitting device. The light emitting device includes a housing, a first light emitting module and a second light emitting module. The first light emitting module is provided with a first light emitting area and is disposed on the housing. The second light emitting module is provided with a second light emitting area and is disposed on the housing and surrounds the first light emitting module. A first luminance in the first light emitting area is higher than a second luminance in the second light emitting area, and the first luminance and the second luminance are separately controlled.

An LED tube lamp comprises a lamp tube; two groups of light boards arranged in the lamp tube, having a first light source and a second light source respectively; and two lamp caps, which are respectively arranged at both ends of the lamp tube. The two groups of the light boards are oppositely arranged in the lamp tube, so that the first light source and the second light source are arranged oppositely, and the light boards are fixed on the inner circumferential surface of the lamp tube.

A LED light tube includes a LED strip with a substrate plate and multiple LED modules. A light passing tube stores the LED strip. The light passing tube has a first portion and a second portion. The first portion has more light passing through than the second portion. A first end cap is attached to a first end of the light passing tube and a second end cap is attached to a second end of the light passing tube. The first end cap and the second end cap each having two pins. A driver is enclosed in one of the end caps for supplying a driving current to the multiple LED modules and controls the multiple LED modules.

An illumination device configured to illuminate an imaging target, an image of which is to be captured by a camera, provided with a current adjusting device configured to adjust a current flowing through the LEDs of four LED-mounted boards on which many of the LEDs are mounted, wherein the four LED-mounted boards are arranged in a four-sided shape centered around the light axis of the camera as viewed from the imaging target, and each of the LED-mounted boards is inclined at a specified angle so that the LEDs of the LED-mounted boards face the imaging target. The current adjusting device is configured to divide an LED-mounted area of each of the LED-mounted boards into multiple illumination areas and to individually adjust the current flowing to the LEDs of each of the LED-mounted boards for each of the multiple illumination areas.
