LED light assembly having heating board

A light assembly including a housing, a plurality of light emitting diodes (LED) on a circuit board, a lens, a lens cover and a heating board positioned within the housing. The heating board is positioned behind the lens and in front of LEDs within the housing, such that light from the LEDs shines through the heating board. The heating board also includes a sensor and a microcontroller to activate, deactivate and control the heating board in response to an outside air temperature.

Low temperature LED lighting system

A lighting system for low temperature environments includes a plurality of light emitting diodes attached to a support member mounted within a refrigeration unit or the like for illuminating contents thereof. A reflector is disclosed adjacent to the light emitting diodes for dispersing the light therefrom. A light transmitting cover overlies the light emitting diodes, and preferably includes non-planar surfaces for dispersing light onto objects within the refrigeration unit. A power supply converts alternating current voltage to a lower direct current voltage for powering the light emitting diodes in a safe manner.

Apparatus and method for controlling lamp of refrigerator

Disclosed are an apparatus and a method for controlling lamps which are provided in a dispenser and a backlight of a manipulation button array. According to the present invention, at least one lamp is provided in the dispenser and an illumination sensor for sensing the surrounding brightness of a refrigerator or a sensor for detecting a user approaching the refrigerator is also provided. There is also provided a memory unit for previously storing a reference luminous intensity, the value of which is capable of being changed by the user. There is also provided a lamp driving unit for selectively controlling the brightness of the lamp by controlling the output signal thereof according to a driving control signal of a control unit. According to the present invention, the user can easily take ice or water from the dispenser because the lamp is turned on. In addition, because the reference luminous intensity can be changed and stored in relation to the surrounding brightness of the refrigerator, it is possible to control the condition for turning on or off the lamp according to the surrounding environment or the user's taste. Moreover, because the dispenser and the backlight are normally illuminated with the minimum brightness, it is easy to use the dispenser, and because the dispenser and the backlight are illuminated with the maximum brightness for a predetermined length of time and then the illumination is gradually returned to the minimum brightness or turned off, it is possible to efficiently use the dispenser.
