A method for adhesively bonding components, in particular a lamp holder on a mounting, wherein the method includes at least the following steps: producing a load-bearing adhesive bond by means of introducing a slowly curing adhesive into or onto an adhesive receptacle between the components; arranging at least one light-transparent fixing element in physical contact with at least one of the components; adhesively bonding the fixing element to at least one of the components by means of introducing a fixing adhesive at fixing bonding points; transmitting light from a light source through the fixing element to cure the fixing adhesive at the fixing bonding points; and long-time curing of the slowly curing adhesive of the load-bearing adhesive bond.

A light emitting device includes a base having a light reflecting surface and having a first side on which the light reflecting surface is provided, light sources mounted on the first side, and a half mirror disposed opposite to the base to reflect a part of incident light and to transmit another part of the incident light. Each of the light sources includes a reflecting layer on an upper surface of each of the light sources. The half mirror has an oblique reflectance with respect to wavelengths of light emitted from the light sources in a case where the light travels obliquely toward the half mirror. The half mirror has a perpendicular reflectance with respect to the wavelengths in a case where the light travels perpendicularly toward the half mirror. The oblique reflectance is smaller than the perpendicular reflectance.

An LED filament light including a bulb, a support bar, at least two electrode wires and at least two LED filament strips. Each LED filament strip including a base, an LED chip is set on the base and an electrode is fixed at both ends of the base. One end of the electrode is electrically connected with an LED chip on the base, the other end of the electrode is electrically connected with an electrode of another LED filament or electrically connected to one end of the electrode wires so that the support bar is fixed to the bulb, and the other end is connected with at least one. As the support bar is set to replace the existing LED filament light core and metal wire, and creatively the LED filament electrodes directly is connected to each other.

In accordance with certain embodiments, systems of lighting components feature multiple illumination panels each having a backing support and, secured thereto, multiple illumination elements. The illumination elements have shapes defined by arrangements of illumination unit cells may be assembled to illuminate an arbitrary two-dimensional area.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal. The signal can be provided intermittently and a carrier wave also provided and modulated at the same time as the signal. When the signal is not being produced, the power on the power line may be power that is allowed to flow without manipulation from an external portion of the power line.

A fastening device for a circuit board of an electrical device can include a body having a first portion and a second portion, where the body has an aperture that traverses therethrough.
