Description

  The present invention relates to an LED lamp.

As the night light, lighting fixtures as described in Patent Document 1 and Patent Document 2 are usually used. As shown in FIG. 8, this luminaire is formed by installing a tungsten lamp B on a lamp support A.
However, the tungsten lamp has not only a large amount of energy consumption, but also has a drawback that the lamp needs to be frequently replaced because of its large calorific value, tungsten being easily burned, and short life.

Further, as shown in FIG. 9, a night-light having a light-emitting diode (LED) lamp C installed on a lamp support A is also known.
However, since the LED lamp C has a small rising dimension from the lamp support portion A, the brightness is uneven depending on the light irradiation direction. In order to prevent this, it is necessary to form a large number of protrusions C2 on the surface of the lamp cover C1 or to make it a frosted surface, and to diffuse and irradiate light. However, the lamp cover C1 has an uneven appearance. Lack of aesthetics, dirt adheres, and light transmittance tends to decrease.

According to the present invention, since the LED is used as the light emitting member, the power consumption can be reduced, and since the lifetime is long, the replacement frequency is low, the heat generation amount is low, and the safety is high.
In addition, light is diffused and illuminated uniformly in multiple directions, and the surface of the outer lamp cover is smooth, so that the appearance is good and it is difficult for dirt to adhere, and the diffusion surface of the inner lamp cover blocks the line of sight from the outside. The circuit board and LED cannot be seen, and the aesthetics increase.

1 to 3 show a first embodiment of the present invention.
As shown in FIG. 1, the LED lamp of the present invention includes an LED (light emitting diode) 13, an LED support 1, an inner lamp cover 2 that covers the LED 13, and an outer lamp cover 3 that covers the outer side of the inner lamp cover 2. With.
A housing recess 11 is formed on the surface of the LED support 1, a circuit board 12 is installed inside the housing recess 11, and an LED 13 is mounted on the circuit board 12.
A conductive member 14 connected to the circuit board 12 protrudes from the back surface of the LED support 1. A coupling portion 141 formed of a screw groove is formed on the outer peripheral surface of the conductive member 14, and one polar terminal 142 is provided on the side surface of the conductive member 14, and the other polar terminal 143 is provided on the distal end surface of the conductive member 14. .

The inner lamp cover 2 is made of a translucent material and is installed in the housing recess 11 to cover the LED 13. As shown in FIG. 2, the outer surface of the inner lamp cover 2 is a diffusion surface 21 in which a large number of concentric protrusions 211 are continuously formed.
The outer lamp cover 3 is made of a translucent material, and its surface is formed to be smooth. The outer lamp cover 3 is attached to the outer periphery of the surface of the LED support 1 so as to cover the outer side of the inner lamp cover 2.

When the LED lamp is used, the LED lamp is attached to the lamp support A as shown in FIG. A screw hole is formed on the surface of the lamp support portion A, one polar terminal A1 is installed on the inner peripheral surface of the screw hole, and the other polar terminal A2 is installed on the bottom surface of the screw hole.
When the conductive member 14 of the LED lamp is inserted into the screw hole and the coupling portion 141 is screwed together, one polarity terminal 142 and the other polarity terminal 143 of the LED lamp are respectively connected to one polarity terminal A1 and the other of the lamp support portion A. The LED 13 connected to the power source through the conductive member 14 and the circuit board 12 emits light.

The light emitted from the LED 13 is projected onto the diffusion surface 21 of the inner lamp cover 2, is uniformly diffused by the protrusions 211 of the diffusion surface 21, passes through the outer lamp cover 3, and is uniformly irradiated in multiple directions.
Since the surface of the outer lamp cover 3 is smooth, not only the appearance is excellent, but also dirt is difficult to adhere. Further, since the diffusing surface 21 of the inner lamp cover 2 blocks the line of sight, the circuit board 12 and the LED 13 cannot be directly seen from the outside, and the aesthetic appearance is further increased.
Note that the diffusing surface 21 may be formed on the inner surface of the inner lamp cover 2, and the inner lamp cover 2 and the outer lamp cover 3 may be colored to color the light emitted from the LED lamp.
