A display apparatus, including a display panel which includes a light emitting element, a storage configured to store a plurality of compensation coefficients corresponding to a plurality of gray levels according to a parasitic capacitance of the light emitting element, and a processor configured to obtain a compensation coefficient from the plurality of compensation coefficients based on at leastone of a position of a scan line and a gray level of scan data, compensate the gray level of the scan data based on the obtained compensation coefficient, and drive the light emitting element based on the compensated gray level.

The invention relates to a mood lamp system, a method of controlling mood lamp, and a mood lamp controlling apparatus. The mood lamp system includes a mood lamp and a mood lamp controlling apparatus that is configured to select a mode of the mood lamp from a plurality of modes including an off mode, a mood mode, and a music mode. In addition, a mood lamp controller is configured to operate the mood lamp based on the mode of the mood lamp. The mood lamp may emit light of a single color in the music mode.

The invention discloses a spreadlight lens and an LED strip-shaped lamp. The LED strip-shaped lamp comprises a circuit board, multiple LEDs arranged on the circuit board in the length direction, and a row of lens sets respectively covering the LEDs in the LED light emitting direction. The lens sets include two spreadlight lenses. The at least two spreadlight lenses are respectively arranged at two ends of the circuit board for deflecting emitted light rays of the corresponding LEDs to the middle part of the circuit board for emitting to reduce the light intensity at two ends of the LED strip-shaped lamp. The spreadlight lens includes optical axis, an emitting surface perpendicular to the optical axis, and an incident surface. The optical axis is inserted in the center of the incident surface. The center of the emitting surface is deviated from the optical axis. An included angle between the center connecting line of the incident surface and the emitting surface and the optical axis is equal to an included angle between the incident surface and the emitting surface, so that the light rays and the emitting surface are deflected corresponding to the optical axis. The LED strip-shaped lamp can prevent obvious light and shade contrast caused by excessive illuminance of two ends of the LED strip-shaped lamp.

The invention provides an excimer lamp having an ultraviolet reflection layer, which can inhibit the degree of illumination decrease even after long-term lighting to efficiently emit vacuum ultraviolet light. An excimer lamp (10) with an ultraviolet reflection layer (30) formed on a part of the inner surface of a discharge container (20) is characterized in that the ultraviolet reflection layer (30) comprises: an accumulation body (A31) formed on at least a part of an electrode (11) at one side; and an accumulation body (B32) formed on at least a part outside the area corresponding to the electrode (11, 12), wherein the accumulation body (A31) comprises silicon dioxide particles containing OH groups and micro-particles having melting points higher than that of silicon dioxide, the accumulation body (B32) comprises micro-particles containing silicon dioxide particles having OH groups, and the concentration of OH groups in the silicon dioxide particles forming the ultraviolet reflectionlayer (30) is more than 10 wt ppm.

The invention relates to an intelligent and energy-saving streetlamp controller and a control method. The intelligent and energy-saving streetlamp controller comprises a controller power supply switch as well as a singlechip, a D / A (Digital to Analogue) converter, a trigger and a thyristor master controller which are respectively connected with the controller power supply switch and electrically connected with each other sequentially, and a conversion switch is further arranged between the trigger and the thyristor master controller. The power supply switch is electrically connected with a main circuit. The thyristor master controller comprises a first thyristor and a second thyristor which are antiparallel and connected in series in the main circuit. The intelligent and energy-saving streetlamp controller prolongs the service lives of a contactor and a tube, reduces the maintenance amount and has the energy-saving effect.
