Indoor lighting seems to be a promising usage for the LED based technology.<\/strong><\/h3>\n

LEDs are semi-conductive devices, while the incandescent, fluorescent and high voltage gas-discharge lamps rely on bulbs or glass tubes that include filament or electrodes, that include gas and various types of coverings.<\/p>\n

LEDs include a small chip, of 0,1mm, made of semi-conductive layers. The LED packages may include one or more chips installed on a thermo-conductive material and usually, encapsulated or including a lens. The resulted device is usually between 7-9 mm long and may generate 30-150 lumens. LEDs can be used individually or in networks. The LED devices can be installed on boards and included in a lighting fitting, an architectural structure or can even have the shape of a \u201clight bulb\u201d.<\/p>\n

A few usages for your house, where the LEDs attributes are turned to advantages:<\/strong><\/p>\n

Lighting the kitchen worktop<\/p>\n

Lighting small sized areas: store-room, closet, fridge, bar, balcony, halls<\/p>\n

Lighting the fields and yards<\/p>\n

Emphasising lighting (instead of lighting spots)<\/p>\n

Lighting the alleys and external stairs<\/p>\n

Areas with sensors<\/p>\n

Refrigerated show-cases<\/p>\n

The users have to pay attention to a few aspects to benefit from the best choice:<\/p>\n

Ask for photometric tests performed in accordance with the international standards<\/p>\n

Ask about the warranty period. 2-3 years is a reasonable period for the outdoor lighting fittings.<\/p>\n

The protection index must be appropriate for the intended usage.<\/strong><\/p>\n

Inquire about the working temperature and its impact on the light efficiency and on the light flow depreciation.<\/p>\n

Check whether the colour temperature is appropriate for the intended usage.<\/p>\n

Check whether the light is not too bright, testing the product, preferably at the intended height, at night.<\/p>\n

Assess the cost considering all aspects: consumed energy, maintenance cost, working checking costs, colour temperature<\/p>\n
