A kind of LED lamp affixed to the ceiling
Technical field
The utility model relates to field of lighting devices, particularly relates to a kind of LED lamp affixed to the ceiling.
Background technology
The advantages such as to have brightness high, low in energy consumption because of it for LED, and the life-span is long, and be widely used in each technical field.LED lamp affixed to the ceiling is the one in the numerous lamp of LED.LED lamp affixed to the ceiling is arranged on house interior, and because light fixture top is more flat, installing near roof, similarly is be adsorbed on roof, so be called lamp affixed to the ceiling.To integral demounting be carried out when LED lamp affixed to the ceiling of the prior art needs repairing, and inconvenience, must replace arrangement, add cost.
Therefore, the technology being badly in need of a kind of improvement solves this problem existing in prior art.
