A lighting system network includes first and second lighting systems in communication with each other. The first lighting system includes an LED controller, and an LED array which includes first and second LED sub-arrays, wherein the LED array is operatively coupled to the LED controller. The first and second wavelength spectrums provided by the first and second LED sub-arrays, respectively, are adjustable in response to adjusting an input signal provided to the antenna.

A cooling system and a control method of the cooling system are provided. The cooling system includes a display device, a temperature sensor, a cooling fan and a temperature controller. The display device includes a backlight module. The temperature sensor is configured in the backlight module. The temperature sensor senses a first temperature of the backlight module and a second temperature of the backlight module. The first temperature is higher than the second temperature. The cooling fan is configured in the backlight module. The cooling fan provides a cooling path. The temperature controller receives the first temperature and the second temperature from the temperature sensor, and controls the cooling fan to enable or disable.

An LED growth light and method for providing light to plants incorporating an LED arrangement, a growth light housing, and a power source. The LED arrangement includes LEDs arranged in individually powered columns to provide relatively uniform disbursement of the light to the plants. The housing includes an accessory rail to attach a variety of optional accessories and internal cooling fins to cool the housing to prevent damage to the power supply and/or to prevent overheating the plants. In addition, the housing includes a fan and end caps which permit the movement of air for the displacement of heat and reduce the intake of moisture or debris into the interior of the LED growth light.

A light-emitting diode illumination type ellipsoidal spotlight, and more particularly, a light-emitting diode illumination type ellipsoidal spotlight which is capable of drastically prolonging the lifespan of a light source part used in the ellipsoidal spotlight, reducing power consumption and costs related thereto, and producing a variety of colors by manufacturing the light source part of the ellipsoidal spotlight is disclosed.

An LED light bulb has a hollow LED support/heat sink (222, 602, 702, 900, 802, 1002, 1102, 1216, 1404, 1502, 1606, 1906) with fins (234, 406, 604, 706, 804, 904, 906,1008, 1106, 1620) extending internally and openings at two ends (230, 232, 1522). Heat generated by the LEDs (238, 908, 1242, 1624, 2504) is conducted through the heat sink fins and is removed by a convectively driven air flow that flows through the LED support/heat sink. LEDs are mounted on multiple external faces (236, 404, 910, 1524, 1622) of the LED support/heat sink thereby providing illumination in all directions. Lenses (1246, 2102, 2104) are provided for the LEDs to make the illumination highly uniform.

A back to back electronic display assembly includes a first display assembly positioned back to back with a second display assembly. A substantially sealed enclosed chamber is positioned entirely between the first and second display assemblies. A first gap is located between the enclosed chamber and the first display assembly. A second gap located between the enclosed chamber and the second display assembly. A fan is positioned to force external air through the first and second gaps.

A dust prevention and heat dissipation module for a color wheel and a light source system employing the same. The color wheel is sealed in a color wheel housing which has an air inlet and an air outlet. The dust prevention and heat dissipation module has a leading-in air channel in communication with the air inlet of the housing, a leading-out air channel in communication with the air outlet of the housing, a filtering device at an inlet of the leading-in air channel and an outlet of the leading-out air channel, and a fan which circulate the air via the leading-in air channel and the leading-out air channel. The air flow caused by the fan realizes heat dissipation of the color wheel, and the filtering device filters the air flowing through the color wheel housing, thereby reducing the amount of dust adhered to the surface of the color wheel.

Disclosed embodiments relate to a combination axial fan, LED lighting system and electric blue killer. The disclosed systems may include a housing forming an air chamber and an axial fan.
