Description

  The present invention relates to a lamp, and particularly has features such as a wide range of applications because it can be mounted on a flat surface such as a lightweight steel ceiling plate, a general ceiling plate, and a wall surface, and is easy to manufacture and assemble and has low cost. It relates to a lightweight steel grid lamp.

  A conventional lightweight steel grid lamp (for example, Patent Document 1) includes a lamp case, a plurality of fluorescent lamps, and a grid lamp cover. The lamp case is a rectangular box that opens downward, and is used for installation on a lightweight steel ceiling plate. A plurality of lamp cases that are installed on the two opposite wall walls of the lamp case. After inserting the fluorescent lamps into the lamp sockets, the grid lamp cover is joined to the opening of the lamp case, and the fluorescent lamp light is emitted by the grid lamp cover composed of the frame and the light reflector provided in the frame. Reflect to obtain a suitable illuminance. However, fluorescent lamps have the disadvantages of glare, high power consumption and low light emission efficiency, and may contaminate the environment. For this reason, lamps using light emitting diodes (LEDs) having features such as glare, low power consumption, and low environmental pollution have become the mainstream in recent years, gradually replacing conventional fluorescent lamps.

  A lightweight steel grid lamp (for example, Patent Document 2 and Patent Document 3) using a light-emitting diode (LED) as a light source on the market at present has a plurality of straight tube LED lamps in a rectangular lamp case opened downward. Has been placed. Each straight tube type LED lamp is provided with a plurality of LEDs and is configured by covering the opening of the lamp case with a diffusion plate. However, such a lightweight steel grid lamp can be attached only to a ceiling plate of a lightweight steel frame, and cannot be attached to a plane such as a general ceiling plate (for example, an RC structure or a wooden board structure) or a wall surface. Since the straight tube type LED lamp was removed and it could not be used alone as lighting equipment, the application range was narrow. In addition, by using a plurality of straight tube LED lamps fixed to the bottom of the lamp case, a light emitting effect similar to that of a fluorescent lamp can be obtained, and a diffuser plate can be used instead of a general grid lamp. There are also things to do. However, the irradiation angle of the straight tube type LED lamp is limited by the lamp case, so that the illumination range becomes small, and the straight tube type LED lamp is directly fixed on the lamp case. May adversely affect the brightness of the lamp. In particular, because it does not have a grid lamp cover, the shape seen from below is different from conventional lightweight steel grid lamps, and replaces existing lightweight steel grid lamps with lightweight steel grid lamps that use straight tube LED lamps as the light source. When doing so, it is necessary to replace all of them together so as not to adversely affect the appearance of the indoor space. Therefore, not only the cost increases, but the grid lamp cover may be thrown away and wasted without being used to the end.

  For this reason, there has been a demand for a lightweight steel grid lamp that does not have the disadvantages of the prior art described above.
