Description

  The present invention relates to a support device in a case where a light emitting module in which a light emitting element such as a light emitting diode is arranged on a substrate is installed on a ceiling surface as an illumination device, and an illumination device using the support device, and in particular, the light emitting module is installed on a system ceiling. The present invention relates to a support device and a lighting device using the same.

  In recent years, suspended T-bars are placed on the ceiling with a predetermined dimension of, for example, 600 mm width or 640 mm width on the ceiling inside a building such as a building, and standardized on each grid. A system ceiling in which a ceiling panel is inserted is used. In such a system ceiling, for example, a ceiling panel having a standard dimension of 600 mm square is dropped into each lattice, and the ceiling panel is supported by an edge portion protruding to the side of the T bar to form the ceiling. For such a system ceiling, there has been proposed a fluorescent lamp unit adapted to the dimensions of the system ceiling so that installation / removal and movement are easy (see, for example, Patent Documents 1 and 2).

  On the other hand, also about the illuminating device using the light emitting module which has arrange | positioned several light emitting diodes on the board | substrate, what has arrange | positioned several light emitting diodes is proposed (for example, refer patent document 3). In addition, there has been proposed a light emitting module provided on a ceiling of a shelf surface, and a plurality of light emitting diodes of the light emitting module provided with a curved reflection portion (see, for example, Patent Document 4).

  In a light emitting module using such a conventional light emitting diode, a metal heat sink or heat radiating piece for improving the heat dissipation of the light emitting diode is installed on the substrate or in the middle of the substrate, or the substrate itself is made of aluminum or the like. It has been proposed to form a metal conductive thin plate with good thermal conductivity, or to form copper through holes, bumps or blocks in the substrate. Further, metal materials are generally used in consideration of heat dissipation even in a light emitting module support device and a lighting device portion using the light emitting module.

  The inventor of the present application proposes to use a light emitting module, which is not limited to the above-described example, in which measures for suppressing a temperature rise are taken, instead of a conventional fluorescent lamp. In the light emitting module proposed by the present inventor, for example, the temperature after 60 minutes and after 120 minutes was both 37 degrees (measurement request from the Tokyo Metropolitan Industrial Technology Research Center: report number 19 Yokomitsu 405-407). That is, when the room temperature is 27 degrees, the light emitting module proposed by the present inventor does not increase to 37 degrees or more under normal use.

  However, conventionally, there has been no support device that can easily install a standardized light emitting module for lighting a light emitting diode on the ceiling by arbitrarily changing the number of the light emitting modules. Therefore, conventionally, an expensive dedicated illumination device with external dimensions formed according to the size of the grid is used for the system ceiling, or a support device that is expensive and requires a lot of man-hours is made by itself, or a general-purpose fluorescent lamp installation The equipment had to be processed for light emitting diodes over time. In addition, such conventional light emitting module support devices are generally used for fluorescent lamps, and therefore, a ballast including a voltage conversion unit such as an inverter can be attached to protect fluorescent lamps that are easily damaged. Therefore, the periphery of the light emitting portion excluding the emission surface is covered with a large and thick plate material, etc., and has a complicated and excessive structure and excessive strength for a light emitting module. For this reason, the design change is not easy, and the illumination row of the light emitting module cannot be easily changed.

  In order to solve the above problem, the inventor of the present invention can easily install the light emitting module on the system ceiling for illumination, and the quantity change and replacement of the light emitting module can be easily removed from the ceiling with a simple configuration. The support device which can be easily implemented only by this was devised (for example, refer to Patent Document 5).

  Further, the inventor of the present invention improves the idea of Patent Document 5 to change the number of light emitting modules in one row, or to replace an adjustment plate or equipment plate when replacing one light emitting module. A support device has been devised in which the number of light emitting modules can be easily changed and replaced in units of one row from the lower surface of the ceiling without removing or removing the entire support device from the ceiling (see, for example, Patent Document 6).

  As the awareness of countermeasures against disasters such as earthquakes in recent years has increased, awareness of countermeasures against collapse has also increased for the ceilings of buildings, and the structural materials for the ceilings are also required to be lighter. For this reason, lighting devices installed on the ceiling have been required to be lighter. However, in the conventional ceiling lighting device and its supporting device, it is necessary to ensure the strength against the load and stress of the power supply device and its supporting device when using the fluorescent lamp, durability against aging deterioration, flame retardancy against fire, etc. Therefore, iron or aluminum having a large specific gravity was used as a raw material for the main components. Therefore, it is difficult to reduce the weight of the lighting device and the support device for the light emitting module.

  Therefore, in order to solve the above-mentioned problems, the present invention enables a light emitting module support device for a lighting device to be easily formed on a system ceiling for lighting and can be molded from a lightweight polymer material. With the goal. In addition, the support device can easily change and replace the number of light emitting modules in units of one row from the lower surface of the ceiling without removing the entire support device from the ceiling.

Arranged in two rows. The interval between the light emitting diodes 102 is defined by the specification of the light emission amount and the heat dissipation performance. The arrangement pattern is not limited to the illustrated form.

  As an advantage when the light emitting diode 102 is used for illumination, first, the luminous efficiency is good with respect to the incandescent lamp, and the power consumption can be reduced. For fluorescent lamps, the higher the power, the higher the efficiency of the fluorescent lamp.

Although it is usually an advantage, it may be a disadvantage in some cases. The light emitted from the light emitting diode has directivity. This property is advantageous when the direction of light irradiation is limited or when irradiating in one direction, but when you want to irradiate light in multiple directions including angles other than directivity or when you want to make it visible Can be a disadvantage. In addition, the disadvantages of light emitting diodes are that the voltage / current condition range of the light emitting conditions is relatively narrow, and the voltage / current exceeding the conditions is likely to break, and the high brightness ones for illumination are expensive. .
