[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-emitting device using LEDs which emit light not only on the front but also on the sides and underneath, using light-emitting diodes, and a light bulb which emits light which is easy on the eyes in all directions. The present invention relates to a light-emitting body and a light-emitting body using a light-transmitting body in which a light-emitting portion that emits light not only at the front but also at an angle is formed.

[0002]

2. Description of the Related Art Conventionally, light emitting diodes have been known as Light.
Emission Diode (or Light
Emitting Diode (LED)
A light-emitting diode element to which a lead frame or an electrode is attached is covered with a transparent resin, for example, an epoxy resin (hereinafter simply referred to as a package), and is called an LED lamp or simply an LED. The conventional LED lamp emits light only in one direction (for example, the front) enough to stimulate eyes, but does not emit light in all directions. Light can be seen only in the state of a point on the side or below. Some LED lamps use a diffusing material in the package to diffuse the light.However, the light is diffusely reflected inside and the amount of light emitted to the outside is reduced, and the light is dark overall. There is a problem that only you can see. Further, in the conventional light bulb, since the filament is heated to a high temperature and emits light strongly, there is a problem that, when the light bulb is directly looked at, the eyes are irritated, the pain is caused, and the filament is easily cut. Further, the light emission of a cross section of, for example, an optical fiber which is one of the conventional light propagators emits light only in one direction (front), but has a problem that it looks very dark from an oblique direction.

The light-emitting element includes one light-emitting element, and the light-emitting element is covered with a plurality of light-transmitting beads. According to this light emitter, the light emitted from the light emitting element passes through a number of beads covering the light emitting element and is emitted to the outside of the light emitter. At that time, the bead refracts and diffuses light passing through the bead in each direction due to the difference in the refractive index between the inside and the surroundings. As a result, bright light can be emitted in all directions of the light emitting body. The following light emitters emit light from the light emitting element in all directions by using a large number of beads.

According to this light emitter, light emitted from the light emitting element passes through the package, further passes through the light diffuser, and is emitted to the outside of the light emitter. When passing through the light diffuser, the light diffuser diffuses light in each direction. As a result, light can be emitted in all directions of the light emitter.

Further, the present invention is a luminous body including at least one luminous element, and a Fresnel lens which is bent so that an included angle of a plurality of lenses surrounding the luminous element becomes a predetermined angle. According to this illuminant, the diffusion angle of the light emitted from the luminous element is limited by the Fresnel lens. As a result, light of sufficient brightness can be supplied only to the necessary places. Further, a light emitting body in which a cover case formed of a Fresnel lens is detachably or fixedly covered can be used.

[0016]

According to the above-described embodiments, the following effects can be obtained.

[0017] LED lamps are more resistant to vibrations than incandescent lamps, do not burn out, consume less than half the power, and consume much less. However, conventional L
The ED lamp emits light so as to stimulate the eyes only in the front, but almost no light can be seen from the side, so that it is rarely used in place of the incandescent lamp. In the light-emitting device (LED lamp) based on the light-emitting diode of the first to fourth embodiments, a light-transmitting spherical or polygonal particle bead is fixed to the surface of a package or a cover case surrounding the package. Or having a spherical or polygonal projection, or having a spherical or polygonal recess, so that the light emitted from the light emitting diode element 1 passes through a large number of beads or projections fixed to the surface, Diffused in each direction. Each bead or protrusion or recess diffuses the light and directs the light to the front (top surface) of the package.
Not only that, but also bright light from the side. The intense light that irritates the eyes, emitted from the light emitting diode elements, is converted into light that is so gentle that the eyes are not painful even when directly stared, by passing through the beads or protrusions of the particles. LED of this embodiment
Since the lamp can visually recognize light from the side and from below, the lamp can be used instead of an incandescent lamp, and power consumption can be significantly reduced. For example, many miniature bulbs are hung on a tree or the like as illumination, but if this is replaced with the LED lamp of the present embodiment, the same effect can be obtained with about ５ of the power consumption.

Further, even in a place where a plurality of conventional LED lamps are used, if the LED lamp of this embodiment is used, bright light is emitted from the front and side surfaces.
Since the number of ED lamps is about 1/2 to 1/5, not only power consumption can be greatly reduced, but also manufacturing costs and resources can be significantly reduced. For example, in a small laminated rotating light, etc.,
Approximately 60 LED lamps are used, but if the LED lamp of this embodiment is used, the same brightness and visual recognition effect can be exhibited with about 15 to 20 lamps. A large number of LED lamps are used for an electric display panel for displaying characters and the like, but this display panel is clearly visible from the front, but is not clearly visible from diagonally or from the side, so that characters and designs cannot be read. Also, when viewed from the front, the light is too strong to stimulate the eyes, causing pain in the eyes. When the LED lamp of the present invention is used, the LED lamp can be clearly seen even when viewed diagonally or from the side. Also, when viewed from the front, the light is gentle on the eyes and does not hurt the eyes. Furthermore, the distance between the LED lamps can be made wider than that of the electric light display panel using the conventional LED lamps, and the lines of the characters and designs can be clearly seen thickly. You can display large letters and designs,
Characters and designs can be displayed clearly and clearly.

The LED lamps using the light diffusers of the fifth and sixth embodiments are made of a light-transmissive material having a different refractive index of light from the material of the light diffuser, so that the width of light emitted from the front can be improved. Can be further expanded, and the visible distance of light can be increased by the length of the light diffuser. Therefore, depending on the application, a plurality of conventional LED lamps are used with one LED lamp of this embodiment. The same effect can be exerted.

In the LED lamp using the Fresnel lens according to the seventh embodiment, the diffusion angle of light can be limited, and light of sufficient brightness can be supplied only to a necessary portion.

With the lure of the eighth embodiment, which is one of the luminous bodies of an arbitrary shape, a lure that shines brightly in all directions can be realized.

In the ninth embodiment, the luminous body based on a light bulb using a filament, which is one of the luminous bodies which emits light directly or indirectly by a filament or discharge, is not suitable for the direct light. It emits bright, eye-friendly light without irritating the eyes as strongly as ordinary light from a light bulb.

The illuminant based on an optical fiber, which is one of the illuminants using the light transmitting member in which the illuminating portion is formed in the tenth embodiment, can be viewed from the front or obliquely. ,
It emits bright and gentle light.
