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 as a lighting device on a ceiling surface, and particularly to a support device in a case where the light emitting module is installed on a system ceiling.

  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 reduced the temperature rise of the light source part by arrange | positioning several light emitting diodes discretely, for example is proposed. (For example, refer to 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).

  Regarding the heat generation of the light emitting module using such a conventional light emitting diode, since the light emitting diode is generally efficient, the heat generation can be reduced when obtaining the same illuminance as compared with the incandescent bulb. However, it cannot be generally said that light-emitting diodes can reduce the amount of heat generation compared to fluorescent lamps in the case of obtaining the same illuminance. In addition, with respect to heat generation, the light emitting diode is generally sealed in a resin package having a low thermal conductivity and mounted on a substrate having a low thermal conductivity, so that heat is likely to accumulate around the light emitting element. . And when temperature rises with a light emitting diode, the lifetime of an element is shortened and luminous efficiency falls. Therefore, a metal heat sink or heat dissipation 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 a metal conductive thin plate with good thermal conductivity such as aluminum. It has been proposed to form copper through holes, bumps or blocks in a substrate.

  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 temperature rise are taken, instead of a conventional fluorescent lamp. In the light emitting module proposed by the inventor of the present application, for example, when it is lit by applying a rated voltage of 50 Hz and 100 V in a situation where the ambient temperature is 27 degrees (power consumption 3.14 {W}, total luminous flux 233 {lm}) After 60 minutes and 120 minutes, the temperature was 37 degrees (measurement request from the Tokyo Metropolitan Industrial Technology Research Center: Report No. 19: Yokomitsu 405-407). That is, when the room temperature is 27 degrees, the light emitting module proposed by the present inventors does not increase to 37 degrees or more under normal use, and the power can be greatly reduced. More specifically, this light emitting module has a length: about 250 mm × width: about 18.5 mm × thickness: 1.6 mm (3.5 mm including a light emitting diode) and power consumption of 3.14 {W }, The amount of light corresponding to a fluorescent lamp of 10 {W} can be irradiated. When a light quantity of 40 {W} is required in terms of a fluorescent lamp, this module may be used by connecting four modules in series or parallel, and the power consumption in that case is only 12.56 {W} Therefore, it can greatly contribute to energy saving.

  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 problems, the inventor of the present invention can easily install the light emitting module on the system ceiling for lighting, and the quantity of the light emitting module can be changed and replaced with a simple configuration to remove the entire lighting device from the ceiling. The support device which can be easily implemented only by this was devised (for example, refer to Patent Document 5).

  However, even when changing the number of light emitting modules in one row or replacing one light emitting module, remove the adjustment plate dropped into the grid for the system ceiling and remove the connector from the back side to emit light. It was necessary to replace the module, or to remove the connector by removing the entire support device from the ceiling and replacing the light emitting module. In addition, conventional incandescent bulbs can be replaced in units of one, and fluorescent lamps can be replaced in units of one. Therefore, it has been desired to change the quantity of the light emitting modules in units of one row without removing the entire support device from the ceiling.

  Therefore, in order to solve the above problems, the present invention can not only easily install the light emitting module on the system ceiling for illumination, but also remove the adjustment plate or remove 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. This cannot be generally stated, but the light-emitting diode is more efficient and consumes less power at least several tens of watts or less.

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. .

  On the substrate 101, wiring for supplying light emitting voltage / current to each light emitting diode 102 is formed by printing a conductor pattern or etching after exposure. The wiring is connected to one end of the lead wire 104 at a connection portion 103 formed on the non-light emitting surface, and a connector 105 for connecting to an external power source or the like is attached to the other end portion of the lead wire 104.

The module 100 may be used as a light source of the lighting device. That is, the edge portions 100 a of the long sides on both sides of the light emitting module 100 are mounted in the left and right groove portions 50 on the long side of one module holder 40.

  In the case of this embodiment, when the required illuminance is high, the module holder 40 can be added to increase the number of rows of the light emitting modules 100. Conversely, as a minimum configuration, one module holder 40 can be provided and the light emitting modules 100 can be arranged in one row. That is, by adding and deleting the module holder 40, the number of rows of the light emitting modules 100 can be set to an arbitrary number within a range in which the light emitting modules 100 can be installed in the grid interval dimension L4 of the system ceiling.

  When using the support device 10 of the present embodiment installed on the system ceiling and replacing the light emitting module 100, for example, the fixing means 90 is removed and the end plate 19 is removed to remove the module holder 40.
