LED Filament Bulb (Light Sensor - Optional +Microwave Sensor) is an upgraded LED filament bulb product designated to save energy in larger installation area such as hotel or residential building corridor. The driver is mounted with a light sensor, which when environment is dark (25Lux at sensor). It is optional to have light sensor bulb to added with microwave sensor, which could only be trigger on in a manned dark environment. A standard microwave sensor bulb work at full power when being triggered, while after 15 seconds (customizable), it will be turned off to save energy. The microwave sensing angle covers 120° and an effective distance of 10m, which means that if the filament bulb is mounted 3m above ground, the sensing radius will be 8m. If the mounting height is as high as 4.5m, the sensing radius will be 5m. It is particular safe and reliable, and could be use both outdoor or indoor with appropriate lighting fixture. The product is certified by TUV and SGS with CE, RoHS and ERP and SAA.

The filament bulb uses a fully encapsuled ceramic filament base with high quality Sanan & Epistar chips. The whole lamp has a high lighting efficacy of (100lm/W – 120lm/W) and color rendering (CRI80-95). We offer full range of color temperature, ranging from 2700-6500K. The product beam angle is 360°.

For bulb body, it is optional to use the most common clear glass to achieve higher brightness. If it is preferable to have more diffused light effect, a semitransparent frosted glass body or an opal glass of white powder coated will be available. The base cap could either be Edison screw or bayonet type. They can be of size E26 | E27 | B22d. The base cap could be made of aluminum in slivery color or copper in golden color.

The LED filament bulb use high quality Linear IC driver to power on, which could be single voltage input (AC120V or 230V) of power factor >0.5, which is optimized with stable light output and reduced flickering. The lifetime of the product is over 25,000 hours, with a warrant period of 2 years.

Light sensor filament bulb is widely applicable to larger open area which usage of bulb is high but human traffic is relatively infrequent. It is particular good in places with good exposure of sunlight in the morning but bulb lighting is necessary at night. It aims at saving energy and reduced manual control in turning on and off numerous bulb light. For instance, in relatively long home walkways which switch on or off of light may require long walking distance, light sensor bulb could automatically regulate the brightness in the environment. For large office premises with large open area or common zones, light sensor bulb could be a wise solution as people come by at different timing zone, while difficulties in locating switches and unnecessary energy consumption due to forgotten switching off could also be resolved. Light sensor bulb could also be used in public washroom, workshops, warehouses as well as long indoor stairways.
