Description

  The present invention relates to a lighting device using a light emitting diode.

Conventional auxiliary lighting devices and indirect lighting devices are generally light bulbs or fluorescent lights, but light bulbs consume a lot of power, and in particular, light bulbs are a fire hazard. In addition, when it falls, the bulbs and fluorescent lamps are broken and the glass of the main body is broken. Therefore, the weight and shape are more than relentless, and there are restrictions on the design and installation place in manufacturing.
On the other hand, light emitting diodes with ultra-low power consumption and semi-permanent lifetime have been attracting attention in recent years, and the field of use has been rapidly expanding due to the development of ultra-high brightness light emitting diodes (for example, Patent Document 1 to Patent Document 1). Four).

However, in these conventional examples, the light bulb is replaced with a light-emitting diode to save power and extend the life, and furthermore, the number of light-emitting diodes is increased by competing with the main lighting device for illuminance. there were. In fact, as auxiliary illumination, there was no difference between light and darkness with a small number of light emitting diodes, and no consideration was given to soft light irradiation.

The diffusing part of the conventional lighting device is a diffusing part provided with irregularities in a transparent resin, and since the distance between the light source and the diffusing part is short, when the structure is diverted to the light emitting diode, the light emitting diode increases in brightness to increase the luminous intensity. The type has a narrow irradiation angle of around 20 degrees. Therefore, an illumination device using a small number of light-emitting diodes cannot diffuse light over a wide range, and the difference between light and dark becomes large. In addition, since the light emitting diode has been originally used as an indicator lamp, the emission color becomes a simple color.
Therefore, the present invention enables the translucent diffuser 2 to irradiate a wide range at a short distance. Furthermore, by providing the diffusion part 2 at an acute angle and increasing the diffusion area and making the light emitting diode irradiation obliquely with respect to the diffusion part 2, it is possible to irradiate a wide range with a small number of light emitting diodes 4 and to make the material translucent By using resin, paper, and cloth, it is possible to select an illumination color different from the light emission color of the light-emitting diode 4 and to lead to a blinding effect inside the apparatus.

  In short, the lighting device of the present invention (Claim 1) includes a case so as to cover a circuit device substrate that emits light from a light emitting diode, irradiates light generated from the light emitting diode to a translucent diffusion portion, and a small number of light passes through the light. It is an illuminating device characterized in that a light emitting diode illuminates a wide range with soft light with little difference in brightness.

Further, the lighting device of the present invention (Claim 2) is formed as an inclined surface in a part of the case so as to cover the circuit device substrate that emits the light emitting diode, and the light generated from the light emitting diode is obliquely diffused into the diffusing portion. It is an illuminating device that irradiates and illuminates a wide range with soft light with a small number of light-emitting diodes with little difference in brightness by passing light.

  The present invention is an auxiliary lighting device using a light emitting diode having a considerable illuminance despite extremely low power consumption. Light emitting diodes have directivity and the light emission angle is narrow, so it was considered a drawback for a wide range of lighting, but by setting a translucent diffuser, soft light and subtle color change setting with little difference in brightness Therefore, the necessary range as auxiliary illumination can be irradiated with a small number of light emitting diodes. In addition, a subtle color change can be set by considering the material and color of the diffusion portion. Since it is the advantage of light-emitting diodes, it is small and lightweight and does not generate heat, so there is very little danger of fire due to heat, and the degree of freedom of the case of the device is increased and it can be mounted in a small space. In addition, even when the normal lighting is turned off at night due to indirect lighting or power saving, the feet and surroundings are brightly lit, the power consumption is extremely low, and the lighting device can be used semipermanently.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. The illuminating device 1 which concerns on this invention is provided with the spreading | diffusion part 2, the board | substrate 3, the case 6, and the adapter 7 in FIG. 1, FIG.

As shown in FIG. 3, a plurality of light emitting diodes 4 and necessary electronic components 5 are attached to the substrate 3, and a circuit (not shown) necessary for turning on the light emitting diodes 4 is formed.

The electronic component 5 is, for example, a resistor, a diode, a capacitor, a Cds cell sensor 5a, and the like, which are necessary depending on the characteristics and number of the light-emitting diodes 4 and are turned on when the Cds cell sensor 5a becomes dark. Also, when using a DC power supply and an AC power supply, the electronic components and circuits used are different. In the illustrated embodiment, it is assumed that the adapter 7 is used to convert the alternating current into direct current to supply power. However, in consideration of the circuit of the substrate 3, the dry battery is built in the lighting device 1. It is also possible to light up the light emitting diode 4 using as a power source.

Furthermore, by considering the voltage of the adapter 7 and the shapes of the electronic component 5 and the connector 10, existing AC adapters (cell phones, OA devices, home appliances, etc.) can be used.

This will be described with reference to the drawings. Light irradiated from the light-emitting diode 4 of the light-emitting unit 20 fixed to the case 6 is transmitted to the diffusing unit 2 via the support 9 on the case 6 formed in a cylindrical shape. Irradiate. However, since the light emitting diode has directivity and the irradiation angle (15 to 50 degrees) is narrow, the translucent diffuser 2 can irradiate a wide range at a short distance. Furthermore, by providing the diffusion part 2 at an acute angle and increasing the diffusion area and obliquely irradiating the light emitting diode with respect to the diffusion part 2, it is possible to irradiate a wide range with a small number of the light emitting diodes 4 and the material is a translucent resin. By using paper and cloth, it is possible to select an illumination color different from the light emission color of the light emitting diode 4 and to lead to a blinding effect inside the apparatus.

In the embodiment, the case 6 is made of bamboo, and by arranging a flower pot, a flower vase, and a modeled object on the gantry 6a, the light-emitting diode illuminating device 1 rich in entertainment suitable for, for example, a display lighting device is provided. be able to.
