Light emitting diode bulb having light intensity

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting diode illumination lamp, and more particularly, to a light emitting diode illumination lamp having improved light distribution to reduce light intensity difference on an irradiation surface by controlling light distribution for a light emitting diode light source.

The illuminance of the irradiated surface with respect to the light source is determined according to the distance between the light source and the irradiated surface, and the illuminance of the irradiated surface decreases in proportion to the square of the distance, so that the farther the distance from the light source is, the lower the illuminance becomes.

The lower the angle with the irradiation surface (located directly below the light source), the higher the light intensity of the light emitting diodes is. Therefore, the direct light distribution is excellent. The larger the angle with the irradiation surface, the sharper the lower illuminance is.

Therefore, when illuminating by using LED lighting or using LED lighting in a street lamp, sufficient illuminance can be secured directly under the lamp, but as the further away from under the light source, the illuminance drops sharply, The lighting overlaps with each other is so dark that there is a problem that does not perform the role of a lamp or a street lamp properly.

This problem occurs in a light emitting diode lamp, in which several light emitting diodes are mounted on a PCB having a predetermined width to have a desired amount of light. The straightness is good but the illumination in the lateral direction decreases rapidly with distance. do.

The present invention is to install the PCB of the LED lamp inclined outward from the center to improve the light distribution of the LED lamp to maintain the illuminance of the irradiation surface sufficiently so that the use of the lamp or street lamp is not limited.

In addition, the present invention by attaching a reflective film to the inside of the PCB or luminaire to improve the light distribution to ensure sufficient illumination.

The present invention mounts several PCBs having a predetermined area in which a plurality of light emitting diodes are mounted inside the luminaire having a predetermined shape, and installs an inclined fixture between the PCB and the luminaire to secure the PCB to be inclined outwardly, A reflective film is attached to the inside of the luminaire to reflect light from the light emitting diode to the light distribution to improve light distribution.It is used for indoor lighting when the luminaire is formed as a ceiling-embedded light. Used.

The present invention mounts a PCB equipped with a light emitting diode in a luminaire, but installs the PCB at an angle so that the light of the light emitting diode is directed from side to side, while attaching a reflective film to the inside of the PCB and the luminaire to improve light distribution. The use of lighting eliminates the problem of poor light distribution.

The present invention relates to a light emitting diode illumination lamp for illuminating the light emitting diode by placing several PCBs having a predetermined area in which several light emitting diodes are mounted inside the lighting luminaire having a predetermined space therein. It is installed so as to face outward from the bottom of the to improve the outer roughness of the irradiated surface while attaching a reflective film to the surface of the PCB and the inside of the luminaire to improve the light distribution.

The present invention is to be installed in the indoor lighting or street lamp to improve the light distribution to the outside of the irradiation surface to maintain the illuminance of the irradiation surface uniformly and to be illuminated in a large area.

The present invention is to install the inclined fixture inside the luminaire used as a ceiling lamp or street lamp to fix the PCB, so that the inclined fixture is inclined toward the outside from the inside of the luminaire to improve the light distribution of the light emitting diode. It is to be.

Hereinafter, the present invention will be described in detail with reference to an embodiment using the indoor lighting, and in the case of using a street light fixture instead of the indoor lighting fixture, it can be applied to a street lamp. It can be applied to all light emitting diode lights that are mounted and used.

The present invention relates to a light-emitting diode lamp 50, the PCB 30 is mounted on the light emitting diode 20 is installed in the interior of the luminaire 10 is installed on the ceiling, the protective cap 40 is covered on the front The inclined fixture 15 is installed to install the PCB 30 in such a way that the center protrudes toward the inside of the luminaire 10 and becomes lower toward the side while the surface of the PCB 30 and the luminaire 10 are installed. The reflection film 60 is attached to the inside of the configuration.

The LED lighting 50 of the present invention is installed in a ceiling mounted to the ceiling, the protective cap 40 is exposed to the front surface, and has a form of a general LED lighting 50, the luminaire 10 Inward) install the inclined fixture 15 to which the PCB 30 is fixed to the front side, but the inclined fixture 15 is inclined toward the outside from the center so that the PCB 30 is directly connected to the LED lamp 50. The light distribution increases from the bottom to the outside.

The luminaire 10 of the present invention is embedded in the ceiling is installed, the inclined portion formed in the inclined inclined surface 11 to the inner side of the luminaire 10 when the PCB 30 is inclined to install the light emitting diode ( While the light of 20) is going straight, it is reflected to increase the light distribution.

The inclination fixture 15 is installed inside the luminaire 10, and the PCB 30 is installed to be inclined from the center to the outside, and the luminaire covered by the PCB 30 fixed by the inclination fixture 15 ( 10 is provided inside the ballast (14), and the front of the luminaire 10 is covered with a protective cap 40 so that the light emitting diode 20 inside the light is not transmitted from the outside.

The inclined fixture 15 may be manufactured using metal or synthetic resin, and the inclined fixture 15 may be fixed to the PCB 30 using a screw or the like, and the inclination angle of the inclined fixture 15 may be fixed. As a result, the inclination angle of the PCB 30 is determined.

The PCB 30 of the present invention has a predetermined area and is fixed by mounting several light emitting diodes 20 on the front side, and to fix the PCB 30 divided into several pieces in one lamp 10. In each PCB 30, a large number of light emitting diodes 20 are mounted and fixed according to desired illuminance.

In the present invention, by attaching the reflective film 60 to the inside of the luminaire 10 and the front surface of the PCB 30 by using an adhesive, the light of the light emitting diode is reflected from the reflective film 60 to increase the light distribution.
