Description

  The present invention relates to an LED lighting device for a ceiling that is attached to a ceiling and illuminates a room.

Conventionally, incandescent lamps, ceiling-exposed fluorescent lamps, and ceiling-embedded fluorescent lamps have been used as lighting fixtures that are mounted on the ceiling to illuminate a room.
Incandescent lamps have been used for a long time since the old days because of their ease of installation and atmosphere, but there were problems with their lifetime, high-temperature heat generation, and brightness against current consumption. For this reason, fluorescent lamp luminaires are used in most homes and offices.
Among these lighting fixtures, an embedded fluorescent lamp lighting fixture (for example, Patent Document 1) that is directly attached to the ceiling has an advantage that the ceiling space can be felt wide, but a fluorescent lamp base incorporating a fluorescent lamp a. A ceiling board opening and a base opening c corresponding to the appliance b are required, and a heavy power supply part d such as a ballast or an inverter circuit is required, and the ceiling T bar e having a T-shaped cross section is directly supported. Alternatively, it is necessary to hang it in the space behind the ceiling with bolts f, etc., and since it is heavy, the construction work is a set of two people, and furthermore, the heat generated by the ballast d etc. cannot be ignored, and the cooling of the air conditioning It was a load.

By the way, a non-white LED having a small calorific value and good luminous efficiency has been developed, and as disclosed in Patent Document 2, a flat EL element is used for small-scale lighting such as an interior lamp. As disclosed in Document 3, it is used as a small-scale nightlight, but a ceiling LED lighting apparatus used in a normal room has not been put to practical use. However, recently, a white power LED lamp for illumination having a luminous efficiency of 70 lm / W and a luminous flux of 145 lm has been developed, and it has become possible to provide an LED lighting fixture for a ceiling used in a normal room.
