Description

  It is a device that incorporates LEDs in a small and light module and scatters and lights up so that the three-dimensional light emitter can emit light evenly with low power consumption. Since the LED module is small and light, even if it is installed in large numbers, the weight burden is small, the heat generation is low and it is safe, and it is suitable as a light source for small to large three-dimensional light emitters. In addition, recent technological advances have increased the luminous efficiency of LEDs, and the required brightness can be obtained with less power consumption.

  Increased luminous efficiency The LED chip allows the necessary brightness to be obtained with a small number of lighting. For this reason, it was found that when a LED module with one to twelve LEDs with a direct current of 3 V to 49 V is constructed and a large number of these are lit in a distributed manner, uniform brightness can be obtained compared to a small light source with a large output.

  Many LED modules do not generate heat even when they are lit, and they have low power consumption and are suitable for distributed lighting. For example, even if 100 modules of 0.6 W are lit, the power is 60 W, and a uniform light emitter can be finished by dispersing the light sources at 100 locations as compared to lighting one 60 W bulb.

  Light sources incorporated into internally illuminated 3D signboards and internally illuminated 3D displays are made for the purpose of emitting light in a certain direction, such as light bulbs, fluorescent lights, and LED bulbs. When used as an internal illumination light source, it is difficult to obtain uniform brightness due to the intensity of illuminance.

  A light source incorporated in a large internally illuminated three-dimensional display has a problem that it is difficult to construct and dispose the light source because the housing to which the light source is attached becomes large and increases in weight.

  Opportunities to produce 3D displays with new technologies and new ideas have increased, but the technology of light sources that make brightness uniform is delayed, and it is not possible to produce uniform brightness and express sufficient appeal. I can't.

  A small and lightweight LED module is used as the light source, and the fixture is attached to a metal housing (8) incorporated inside the three-dimensional light emitter. Adjust the installation to the optimal distance and orientation. By attaching a large number of small and lightweight LEDs, the light source is dispersed, and uniform brightness can be obtained when installed at appropriate positions.

  Small light source LED modules have a low operating voltage of 3V to 48V DC and are safe and generate little heat. For this reason, it is possible to install a large number of dispersed parts where necessary. In addition, since it can be installed in an appropriate orientation when many are installed, it is possible to display a three-dimensional display object with uniform brightness.

  Small light source LED modules are direct current and low pressure. If the metal housing constructed inside the 3D display object is used as the ground, the wiring of the LED light emitting part can be wired with one anode, so the wiring is simplified and the manufacturing cost is reduced.

  Small light source LED modules are lightweight, so even if a large number of them are installed, there is no burden on the weight. The use of a lightweight metal such as aluminum as the housing for mounting a large number of the housings further reduces the overall weight, which simplifies the handling of internally illuminated three-dimensional displays.

  3D display objects can be produced with new ideas and new technologies. For example, three-dimensional light emitters using Japanese paper, lighting equipment using three-dimensional signboard blow molding using vacuum molding, etc., which have previously been difficult to install and have been difficult to produce, can be optimally emitted with the compact light source of the present invention, so that sufficient appeal can be made. become.

  In order to energize, a positive electrode is usually wired and a negative electrode is passed through a metal enclosure to energize. However, depending on the installation location and surrounding environment, a negative electrode may be wired and the plus electrode may be energized from the metal enclosure. Alternatively, each LED module may be connected with two plus and minus wires.

  By realizing stereoscopic light emission with low power consumption LED modules, it is possible to produce the brightness from the inside by distributing the necessary light to the necessary places. It can be used from small light emitters to super large light emitters, and it is light and uniform in brightness, which can reduce manufacturing costs as well as appeal for light emitters.

  Fluorescent lamps and light bulbs are used as light sources for signs and display objects that emit light from three-dimensional objects. They are made as illuminators that illuminate in one direction, and it is necessary for the internal illumination of a three-dimensional object to emit light as uniformly as possible without wasting light, which requires a large number of light sources. Fluorescent lamps and light bulbs have a large number of mounting brackets, increase in weight, and the mounting method is robust and complicated. In the present invention, the light-emitting body is small and light, and the burden of weight is small even if a large number of light-emitting bodies are installed. Further, by screwing (9) the metal housing (8), minus wiring is completed, and wiring work is reduced. Reduce production costs.

  The negative electrode wiring can be omitted by arranging the metal casing (8) inside the three-dimensional light emitter and fixing the LED module (12) to the casing. The light-emitting body is small and light, and can be fixed by determining the required orientation and screwing (9). The power consumption of the LED module is small, and even when many LED modules are installed, the power consumption is small. For example, even if 100 0.6W lights up, it can be done with a small power of 60W.

  It can cope with various shapes of a three-dimensional light emitter. It corresponds to a Y-shaped light emitter that is straight, circular, or branched in the middle. The metal casing (8) provided inside can fix the LED module (12) to the casing, so that necessary light can be supplied to a necessary place, and a three-dimensional light emitting body with appealing power is completed.

  The LED module emits light with low power consumption. The power required for lighting is low, and there is little heat generation. For example, in the case of a light emitting body with three LEDs lit, a current of 5 A is generated even if 100 lit with 12 V DC, and the heat generation amount is very small. Low voltage and excellent safety.

  A small LED module consumes only a small amount of power. This is suitable for limited power use. For example, in combination with solar power generation or a power generation device using natural energy, it is possible to store limited natural energy and use it repeatedly for a long time. For example, it can be used for a wide range of applications such as outdoor lights, evacuation guide lights, road signs, sidewalk guide lights, and the like.
