Description

  The present invention relates to a solid light-emitting element bulb.

Conventionally, light bulbs used for various purposes emit light by heating of filaments etc. when energized, and most lighting fixtures that use light bulbs are equipped with reflectors to effectively use the light emitted from the bulbs. It has been.

In recent years, development of a light bulb using a light emitting diode as a light source has progressed, and it has begun to be used for various purposes. However, the chip LED has high diffusibility of radiated light, and a chip LED that can emit 1 Lx light amount at 1 m has not been developed. In addition, a bullet-type light emitting diode in which a lens is integrally formed with an acrylic resin on a chip LED emits radiated light at a narrower angle than the lens portion at the top of the head to increase the luminance. Therefore, even if you show materials and prototypes from trading companies and companies that develop LED bulbs and products that use LED, and from the development department, chip LEDs and shell-type LEDs can be used to produce bright LED products. Rely on increased use. However, since 200 chip LEDs are arranged, there is no reason that it becomes 200 times brighter, and it is only about 32 Lx per 1 m.

  The problem to be solved by the present invention is that the currently sold light bulb emits light by heat generation by energization using a filament as a light source, so that excessive energy loss due to heat generation is large, metal fatigue due to heat generation of the filament and power on / off・ It was extremely vulnerable to vibrations, and it took a long time and effort to cause the ball to run out in a very short time and to get burned or injured when replacing the bulb. Therefore, the development of a light bulb using a solid light emitting element as an alternative light source of the conventional filament is urgently being made, but the LED sold in general is subjected to a shell-shaped acrylic resin molding to increase the luminance value, It is manufactured in a state where 90% or more of the total amount of radiated light is condensed and emitted from the top of the LED with a narrow emission angle. Reflectors for increasing the amount of light in general proof devices are generally installed from the periphery of the bulb insertion part to the front of the bulb obliquely, and are made so that the position of the filament when the bulb is installed is reflected on the entire surface. ing. When radiated light is radiated forward from the top of the head at a narrow angle like a bullet-type light emitting diode, no light is irradiated on the reflector. It is an object to provide a power-saving light bulb using a solid light-emitting element that requires little replacement of the bulb.

The solid-state light-emitting element bulb of the present invention is characterized in that a plurality of solid-state light-emitting elements are used as light sources instead of the filament of the bulb.

The solid-state light-emitting bulb of the present invention is characterized in that a light-emitting portion is installed inward from the top of the bulb using a single solid-state light-emitting device as a light source instead of the filament of the bulb.

The solid-state light-emitting element bulb of the present invention uses a single solid-state light-emitting element as a light source instead of the filament of the bulb, and the radiated light emitted from the light-emitting portion is emitted from the light-emitting portion to the top of the light bulb where the light-emitting portion is installed from the central portion of the bulb It has a reflection mechanism for diffuse reflection.

The solid state light emitting device bulb of the present invention has a reflection mechanism for diffusing and reflecting the radiated light emitted from the light emitting portion in the vicinity of the socket portion of the light bulb where the light emitting portion of the solid state light emitting device bulb of claim 2 is installed inward from the top of the bulb. It is characterized by having.

In addition, the solid-state light emitting device according to the second aspect of the present invention has a spherical mirror (concave mirror) in the socket portion of the solid light-emitting element bulb according to the present invention, and the light-emitting portion is disposed near the focal point of the spherical mirror (concave mirror). It is characterized in that the radiated light emitted from the light emitting portion of the element is made into parallel light or diffused light.

Further, the present invention is characterized in that an acrylic resin mixed with a reflective material is formed in a hemispherical shape or a bullet shape in a light emitting portion of a solid light emitting element and attached to a socket.

A power bulb can be provided.

Even if the LED is simply manufactured in the shape of a light bulb, the emitted light of the LED has a narrow directivity angle and high light diffusivity. Because of its high light diffusivity, it cannot be irradiated 2m away. However, since the solid light-emitting element bulb of the present invention diffuses and reflects the radiated light of the solid light-emitting element by the reflecting mirror and reflects it to the entire reflector of the lighting apparatus, the original illumination ability of the lighting apparatus can be obtained.

In addition, the solid-state light emitting device according to the second aspect of the present invention has a spherical mirror (concave mirror) in the socket portion of the solid light-emitting element bulb according to the present invention, and the light-emitting portion is disposed near the focal point of the spherical mirror (concave mirror). By making the radiated light radiated from the light emitting part of the element into parallel light or diffused light, it is possible to obtain the same effect as using a lighting fixture with a reflector even with a single lamp body. Since the radiated light is reflected on the entire spherical mirror (concave mirror), if it is set to diffused light, it can be lit in an area equivalent to 100 LEDs with a single solid-state light-emitting bulb and can be viewed from an oblique position on the signboard, making it huge and low-cost・ Manufacturing of energy-saving signs, etc. becomes possible.

Furthermore, by forming and attaching an acrylic resin mixed with a reflector in the light emitting part of the solid light emitting element bulb in a hemispherical or bullet shape, the total amount of radiated light is diffusely reflected by the reflector in the acrylic resin and irradiated forward. Most of the light is diffusely reflected in the surroundings, and the radiated light is diffusely reflected and the entire acrylic resin emits light, so that it can be used instead of a filament light bulb.
