Description

Aroma lamp with LED

The present invention relates to a directional (aromatic) lamp, and more particularly, to an LED directional lamp which is heated by the heat of an LED, which is a light source,

In general, a lamp can be classified into a mood for producing an elegant atmosphere of the interior and a lighting for illuminating the interior of the room.

In case of mood or the like, it is possible to adjust the intensity of light emitted from the bulb by providing a translucent shade around the bulb (including incandescent lamp, three-wavelength bulb, and fluorescent lamp) to provide soft lighting or to adjust the direction of the illumination light by providing opaque shade . In addition, by adding a pattern or color to the shade, it gives the effect of a shadow with a light shade or provides a colored light. On the other hand, moods using LEDs have recently been supplied. In this case, since the LED has a very high heat generation temperature, it has to have a separate heat sink for cooling it.

On the other hand, in the case of an indoor mood or the like, a lamp is provided which is provided with a fragrance and is designed to emit a fragrance by volatilizing the fragrance by the heat emitted from the bulb or the LED.

However, in the case of conventional fragrance lamps, the structure is such that the antifungal agent is positioned close to the bulb. Particularly, in the case of an LED lamp, since a structure in which a liquid aromatic agent is accommodated and a heat sink is brought into contact with the lower surface to volatize the fragrance, LED light can only be irradiated downward.

1 to 3, the LED directional lamp according to the present invention includes a body 100, an LED substrate 200, a diffusion plate 300, a heat sink 400, a cap 500, a lid 600 ). In addition, the present invention includes conventional electrical structures and components for causing the LED to emit light by an external power source.

The body 100 includes a fixing jaw 110 formed on an upper rim of the shovel 500 and a receiving groove 120 recessed on the upper surface of the shovel 500 to receive the LED substrate 200. The receiving groove 120 A mounting projection 130 protruding from the central portion of the receiving groove 120 so as to be inserted into a lower central portion of a substantially cup-shaped heat sink 400; As shown in Fig. In this case, when the electric wire 160 connected to the external power source and the plug are accommodated in the lower part of the body 100, the opened space and the electric wire 160 connected to the LED board 200 are passed through the accommodating space, The wiring groove 150 may be formed in the lower portion of the body 100 so as to be exposed. Of course, the lower surface of the accommodation space may be closed by attaching a separate member. A non-slip pad may be attached to the bottom of the body 100 in contact with the floor. Here, the body 100 may be made of ceramics or may be made of a common material.

The LED substrate 200 is substantially donut-shaped, and a plurality of LEDs capable of emitting one color or two or more colors are mounted. A touch sensor (not shown) is mounted on the LED substrate 200 to allow the LED to emit light when one of the body 100 and the cap 500 is touched. Here, the touch sensor may be configured such that all the LEDs emit light by one touch, the brightness may be adjusted according to the number of touches, and the emission color of the LED may be changed every touch. The LED substrate 200 is disposed on the seating protrusion 130 provided in the receiving groove 120 of the body 100.

The diffusion plate 300 has the same or similar shape as the LED substrate 200 and is made of a translucent or transparent material that is placed on the upper surface of the LED substrate 200. Accordingly, the diffusion plate 300 can diffuse the strong linear light emission of the LED, thereby lowering the illuminance and minimizing the glare.

The heat sink 400 has a lower surface closed and an upper surface opened and includes a fixing groove 410 in which the fixing protrusion 140 protruded in the receiving groove 120 of the body 100 is inserted . The heat sink 400 can lower the temperature inside the cap 500 by transmitting heat generated from the LED to emit light. In addition, a liquid or solid phase direction material that emits a fragrance while being strongly volatilized by heat is accommodated in the heat sink 400. Accordingly, the heat sink 400 conducts the heat of the LED and transmits the heat to the directional material, thereby making it possible to reduce the temperature inside the shade 500, and to allow strong incidence of the directional material. As shown in FIG. 2, the shape of the heat sink 400 may be various shapes that can accommodate directional materials including a cup shape, and may be manufactured by machining a plurality of holes while closing the upper surface. Meanwhile, the heat sink 400 may be made of a ceramic material, a metal material having a high thermal conductivity, or may be made of various materials.

The shoulder (500) is manufactured at a predetermined height so that the lower portion is placed on the fixing jaw (110) of the body (100). The cap 500 may be formed in a substantially hollow cylindrical shape, or may be formed into a character shape such as an animal shape including a bear shape or a cartoon character as shown in FIG. Here, the upper surface of the cap 500 is opened to allow the heat inside the cap 500 to be discharged to the outside.

The lid 600 is mounted on the upper surface of the shade and is made to have at least one hole of various shapes including star, moon, and the like. The lid 600 may be simply a manhole, a cap, or other various shapes.

4 is a side sectional view showing another embodiment of the lower part shown in Fig. 5 is a side cross-sectional view illustrating another embodiment of the lower portion shown in Fig.

The embodiment of the LED directional lamp according to the present invention relates to the shape change and function enhancement of the heat sink 400 as shown in Figs. 4 and 5, and the function change of the diffuser plate 300 accordingly. Therefore, the embodiments of the heat sink 400 and the diffusion plate 300 will be described in detail below, and other elements will be replaced with the above description, and briefly referred to as necessary.

4, the heat sink 400 includes a fitting groove 420 in which a central rim portion of the diffusion plate 300 is fitted, and a central projection 430 protruding upward from an inner central portion of the heat sink 400, . At this time, the fitting groove 420 may be formed in one or a plurality of grooves along the outer circumferential surface of the lower side of the heat sink 400. This structure allows the diffusion plate 300 to be fitted into the fitting groove 420 so that the heat of the LED can be transmitted to the heat sink 400 through the diffusion plate 300 more quickly and more and ultimately, The volatility of the emulsion can be enhanced and the perfume-dispersing effect can be further improved. In addition, the central protrusion 430 may allow the heat of the heat sink 400 to be more efficiently transferred to the directional material while widening the contact area between the directional material and the heat sink 400.

As shown in FIG. 5, the heat sink 400 has a fitting recess 420 of FIG. 4 and a heat collecting space 440 inside a side portion having a predetermined height. At this time, the heat collecting space 440 may be manufactured so as to communicate with the fitting groove 420 or may be manufactured to be disconnected. Accordingly, when the heat of the LED is transmitted to the heat sink 400 through the diffusion plate 300 in a state where the diffusion plate 300 is fitted in the fitting groove 420, a part of the heat is collected in the heat collecting space 440. That is, part of the heat transferred to the heat sink 400 is not immediately discharged into the cap 500, but remains in the heat collecting space 440. The heat in the heat collecting space 440 has a temperature higher than a temperature emitted from the heat sink 400 due to mutual action and the heat of such high temperature causes the volatilization of the directional material contained in the heat sink 400 And the effect of enhancing the incense can be further improved.

Here, the heat sink 400 further includes a plurality of heat dissipation openings 450 for dissipating the heat inside the heat collecting space 440 to the outside. The heat dissipation unit 450 prevents the heat collection efficiency of the heat collecting space 440 from being lowered due to the internal air being not convected by the heat dissipation space 440 and prevents the air inside the heat collecting space 440, Can be released.

4 and 5, the diffusion plate 300 may be made of a translucent or transparent material having a high thermal conductivity and having a high thermal conductivity in order to further increase the thermal conductivity of the heat sink 400, Only the portion in contact with the heat sink 400 may be made of an opaque material having a high thermal conductivity and then attached to other parts.

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims, rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and equivalents of the claims are to be construed as being included within the scope of the present invention do.
