Description

The present invention relates to a lamp using an O-ring including a phosphorescent material that emits light when receiving light from a light source.

In recent years, light bulb-type LED lamps that are alternatives to incandescent light bulbs have become widespread.
In addition, as LED output increases, LED lamps are also used for signboard illumination used outdoors, and LED lamps with improved waterproof performance have been developed (Patent Document 1).
In addition, lamps and lighting fixtures have been proposed in which a phosphorescent material is applied to a part of a lamp or lighting fixture, and a portion where the phosphorescent material is applied by light from a light source emits light (Patent Literature 2 and Patent Literature 3).
In these lamps, the part where the phosphorescent material is applied emits light after the lamp is extinguished, so that appropriate illuminance can be obtained and safety can be improved during a power failure, etc. Since it emits light, a decorative effect can be obtained.

JP 2012-119283 A Utility Model Registration No. 3040839 JP 2005-294050 A

In general, in order to use a phosphorescent material, a method of applying a phosphorescent paint to a part of a lamp or a lighting fixture is employed, and thus a step of applying and drying the phosphorescent paint is required.
The present invention does not require a step of applying and drying a phosphorescent paint, and can use a phosphorescent material for a lamp or a lighting fixture, and aims to improve safety and obtain a decorative effect due to light emission of the phosphorescent material. To do.

The lamp according to the present invention is a lamp having a translucent cover attached to a housing provided with a light source, and the housing and the translucent cover are fixed with a caulking agent, and the housing and the translucent A packing containing a phosphorescent material is installed between the protective covers.
Furthermore, in the lamp, the light source may be a light emitting diode.
Furthermore, in the said lamp | ramp, the luminescent color of the said light source and the luminescent color of the said luminous material may differ.
Furthermore, in the lamp, the packing may be made of silicon.
The luminaire according to the present invention is a luminaire having a fixture main body holding a lamp therein and a translucent cover attached to the fixture main body, and the fixture main body and the translucent cover are made of a caulking agent. A packing including a phosphorescent material is installed between the fixture body and the translucent cover.

According to the present invention, since the packing containing the phosphorescent material is used, the waterproof performance can be improved.
Further, by emitting light after the packing is turned off, it is possible to improve safety and obtain a decorative effect.
Moreover, since the packing containing the phosphorescent material is only installed in the lamp or the lighting fixture, a step of applying and drying the phosphorescent paint is not required in order to use the phosphorescent material.

It is sectional drawing which shows the internal structure of the LED lamp which concerns on this invention. It is an enlarged view of packing vicinity in FIG.

Embodiments of a lamp according to the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same element in a figure, and the overlapping description is abbreviate | omitted.

FIG. 1 is a cross-sectional view showing the internal structure of an LED lamp according to the present invention.
The LED lamp 1 is an LED lamp used for outdoor signboard illumination or the like.
A housing 6 including a side wall 2, a base plate 3, a radiation fin 4, and a body portion 5 is provided.
The LED substrate 8 provided with a plurality of LED elements 7 is fixed to the base plate 3 by screws, and the base plate 3 is integrally formed with the base plate 3 on the opposite surface of the base plate 3 where the LED substrate 8 is installed. The formed heat radiation fins 4 are formed, and the heat radiation from the LED elements 7 is radiated.
A cylindrical body 5 is integrally formed at the center of the base plate 3, and a lighting circuit 9 for lighting the LED element is mounted inside the body 5 via an insulating sheet 10. Has been.
A side wall 2 is formed inside the outer peripheral portion of the surface of the base plate 3 where the LED substrate 8 is installed, and a translucent cover 11 covering the LED element 7 is screwed onto the inner peripheral surface of the side wall 2. Has been.
A base 13 is attached to the cylindrical body 5 via an insulating member 12, and the LED lamp 1 is turned on by supplying electric power from the base 13 to the lighting circuit 9.

FIG. 2 is an enlarged view of the vicinity of the joint between the housing 6 (side wall 2) and the cover 11 in FIG. . The packing 14 is an O-ring having a cross section of O and is made of silicon.

The packing 14 containing the phosphorescent material receives light from the LED element 7 that has passed through the translucent cover 11 and emits light. Since the light emission of the packing 14 is weaker than the light emission of the LED element 7, the light emission of the lamp is hardly affected when the LED lamp 1 is turned on.
After the lamp is turned off, the phosphorescent material contained in the packing 14 continues to emit light, so that the light emission in the form of the packing 14 is visible. For this reason, since the presence of the lamp can be known even after the lamp is turned off or during a power failure, the safety can be improved.
Moreover, since the light emission in the form of the packing 14 is obtained, a decorative effect after the light is turned off can be obtained.

Further, although the lamp is generally white (or light bulb color), the decorative effect can be enhanced by the difference between the emission color of the lamp and the emission color of the phosphorescent material.
In addition, by emitting light in blue or green, the visibility in a dark place is increased, and the visibility of the lamp can be enhanced even with a small amount of light in a dark place such as after being turned off.

The method for attaching the cover 11 to the housing 6 is as follows.
A groove 15 corresponding to the shape of the cover 11 is formed in the base plate 3 inside the side wall 2, and a caulking agent 16 is applied to the groove 15. Next, since the cover 14 is fixed by screwing the cover 14 on the side wall 2, a process of applying and drying a phosphorescent paint is not required in order to use the phosphorescent material.
By providing the packing 14 and the caulking agent 16 in this manner, the housing 6 and the cover 11 can be waterproofed.

Moreover, the packing containing the phosphorescent material can also be used for a lighting fixture.
By using a packing containing a phosphorescent material between the fixture main body of the lighting fixture and the translucent cover, it is possible to obtain the effect of enhancing the safety after turning off and the decorative effect, like the lamp.
