Abstract: A lampholder system comprises a lampholder having a center section for holding bi-pins on an endcap of a linear tubular lamp, a securing mechanism and a locking mechanism. The center section has a securing mechanism for securing the bi-pins on the endcap of the linear tubular lamp in the center section. The locking mechanism, when applied to the lampholder, prevents the bi-pins on the endcap of the linear tubular lamp from being removed out of the lampholder, consequently preventing the linear tubular lamp from being removed out of the lampholder.

Abstract: A color temperature fusion lighting apparatus includes a first light source with a first color temperature, a second light source with a second color temperature, and a driver circuit. The driver circuit operates the lighting apparatus in two modes. In the first mode, the driver circuit operates the lighting apparatus in a first linear combination of the first light source and the second light source, resulting in a first operating color temperature for the lighting apparatus. In the second mode, the driver circuit operates the lighting apparatus in a second linear combination of the first light source and the second light source, resulting in a second operating color temperature. Moreover, the driver circuit is configured to alternate the operation of the lighting apparatus between the first mode and the second mode at a frequency F between 35 to 45 Hz, resulting in a blended color temperature of the first operating color temperature and the second operating color temperature for the lighting apparatus.

Abstract: An LED lamp includes an elongated housing, LED arrays, a rechargeable battery, a controller circuit, two drivers, a charging circuit, and a battery backup user interface. The first driver converts an external power to drive the LED array whereas the second driver draws power from the rechargeable battery to drive the LED arrays during power outage. The charging circuit charges the rechargeable battery during normal operation. The battery backup user interface includes a battery charging indicator indicating the charging status of the rechargeable battery. The battery backup user interface also includes a battery shutoff switch configured to allow a user to enable or disable the rechargeable battery. In some cases, the battery backup user interface further includes a test button configured to allow the user to trigger a test of the rechargeable battery.

Abstract: A multi-band germicidal irradiation apparatus includes a radiation source, a driver, and an optical filter. The radiation source emits wavelengths in three wavelength bands, 190˜230 nm, 230˜315 nm, and 315˜700 nm. The optical filter is a band-stop filter that filters the wavelength in a wavelength range of 240˜315 nm and permits the wavelength in wavelength ranges of 190˜230 nm and 315˜700 nm to pass through. The radiation source may include an excimer lamp having a gas or mixture of gases, or it may include one or more light emitting diodes (LEDs). When the apparatus further includes a controller, the controller is configured to limit a total dispensed ultraviolet (UV) dosage (TDD) emitted by the apparatus over a predefined period not exceeding an UV threshold limit value (TLV) dosage defined by American Conference of Governmental Industrial Hygienists (ACGIH).

Abstract: A lighting device that comprises a housing, a first visible light source, a second visible light source, an air filter, an airway, and an air circulation mechanism for each airway. The first visible light source contributes to the light output of the device, whereas the second visible light source is responsible for germicidal irradiation by activating a visible-light activatable photocatalytic coating on the air filter. The airway has an air inlet and an air outlet. The air circulation mechanism sucks an ambient air through the air inlet, forces the air through the air filter, and releases the air through the air outlet. The air filter traps airborne particles. The second visible light source is disposed adjacent to the air filter and activates a photocatalyst material in the antiviral photocatalytic coating. Airborne microbials trapped by the air filter are decomposed by the activated photocatalyst material in the antiviral photocatalytic coating.

Abstract: A circadian entrainment enhancement device includes a housing, a first directional light source, a second directional light source, and a driver. During daytime, the driver turns on the first directional light source with a high melanopic ratio to enhance the daytime circadian entrainment of a user. During nighttime, the driver turns on the second directional light source with a low melanopic ratio to enhance the nighttime circadian entrainment of a user. A more advanced version of the present disclosure uses a light sensor, a memory module, and a computation module to calculate the necessary light output of the device by factoring the ambient light level into consideration. An even more advanced version of the present disclosure uses a distance sensor to adjust the light level of the light sources according to the distance between the device and the user.

Abstract: A lighting device may include a driver base and a plurality of elongated light tubes. The driver base may include a driver configured to convert an external alternating-current (AC) power to a direct-current (DC) power and supply the DC power to the plurality of elongated light tubes. A first side of the driver base may have an electric connector connecting to an external AC power source. Each of the plurality of elongated light tubes may protrude independently out of a second side of the driver base. An aggregate lighting angle of the plurality of elongated light tubes may be 360 degrees.

Abstract: A spectral power distribution (SPD) fusion lighting apparatus includes a first visible light source with a first SPD, a second visible light source with a second SPD, a driver circuit, and a controller. The first SPD is different than the second SPD markedly in a 50 nm wavelength range. The controller toggles the turning on of the first visible light and the second visible light at a frequency greater than 25 Hz. The first visible light source is turned on during one half of the duty cycle, whereas the second visible light source is turned on during the other half of the duty cycle. The first visible light source and the second visible light emit similar light outputs and have similar chromaticity coordinates on the CIE 1931 color space chromaticity diagram. In some embodiments a sound wave generator is used to generate a sound wave at the same frequency.

Abstract: A germicidal lighting apparatus with visible glare includes a first light source, a second light source, a first driver, a second driver, and a controller. The first light source emits a light in a 180˜280 nm wavelength range and the second light source emits a light in a visible wavelength range greater than 400 nm. The second light source is positioned adjacent to the first light source and serves as a visible glare source to deter an occupant from looking at the apparatus directly. The controller can turn on both the first light source and the second light source simultaneously to produce a unified glare rating (UGR) greater than 16. The apparatus dispenses over a prorated 8-hour period an irradiation dosage greater than American Conference of Governmental Industrial Hygienists (ACGIH)-specified Eye Threshold Limit Values (TLV) but less than ACGIH-specified Skin TLV to a substance or surface.
