Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a lamp structure that can produce a lighting effect with purification of the ambient air, especially suitable to be served as a nightlight or other similar devices.

DESCRIPTION OF THE PRIOR ART

Since modem man has a higher requirement for the quality of domestic life, for example, for relaxing the body and mind and creating a good environment, an aromatherapy lamp is usually employed. Most of conventional aromatherapy lamps use a candle or a tungsten light bulb as a heating medium to allow the essential oils with water to be evaporated into the environment. Generally, the structure of a conventional aromatherapy lamp includes an essential oil container on a ceramic lamp, in which a candle or a tungsten light bulb is installed for heating the container to allow the essential oil contained therein to be evaporated, thereby creating a fragrant environment to achieve the goal of soothing the body and the mind.

Although the lamps employing candles can spread the scent of the essential oils, the candles may create an unpleasant odor in a room during the burning process, and produce carbon dioxide from burning oxygen, which is bad to the health. Furthermore, a burning candle can bring a potential risk, especially while the user is in sleep. As to the lamps employing tungsten light bulbs, since most of the electrical energy used by the tungsten light bulbs is converted into unavailable heat energy, they are not an ideal means to create fragrance for the environment.

Thus, there is a need to develop a safe and environment-friendly lamp structure that can overcome the drawbacks of the conventional aromatherapy lamps.

The base defines an opening at a top thereof and a plurality of air holes at a bottom thereof, and provided with an electrical plug and a control switch at a periphery thereof The interior of the base is provided with a control circuit board including a light module and a negative-ion generator, wherein the control circuit board is electrically connected with the electrical plug and the control switch provided at the periphery of the base. The light-passing body is fitted into the opening defined at the top of the base, corresponding to the light module, so that the light emitting from the light module can pass through the light-passing body. The shade is mounted on top of the base, wherein the shade is configured to be a hollow cylinder defining a plurality of light-through holes on a periphery thereof, whereby the light emitting from the light-passing body can go through the light-through holes of the shade.

According to one aspect of the present invention, the control switch is a 3-position switch, which includes a first position, a second position, and a third position, whereby the first position can control the light module, the second position can control the negative-ion generator, and the third position can control both of the light module and the negative-ion generator.

According to another aspect of the present invention, the interior of the shade is furnished with a perfume bottle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, the lamp structure of the present invention generally comprises a base 11, a light-passing body 21, and a shade 31. The base 11 defines an opening 12 at a top thereof and a plurality of air holes 13 at a bottom thereof, and provided with an electrical plug 14 and a control switch 15 at a periphery thereof The interior of the base 11 is provided with a control circuit board, the front side of which is provided with a light module 16 containing at least one LED while the rear side of which is provided with a negative-ion generator 17, wherein the control circuit board is electrically connected with the electrical plug 14 and the control switch 15 provided at the periphery of the base 11. The light-passing body 21 is fitted into the opening 12 defined at the top of the base 11, corresponding to the light module 16, so that the light emitting from the light module 16 can pass through the light-passing body. The shade 31 is mounted on top of the base 11, wherein the shade 31 is configured to be a hollow cylinder defining a plurality of light-through holes on a periphery thereof, whereby the light emitting from the light-passing body 21 can go through the light-through holes of the shade 31.

The control switch 15 provided at the base 11 can be a 1-position switch, which can simultaneously control the light module 16 and the negative-ion generator 17. Alternatively, the control switch 15 can be a 3-position switch, which includes a first position, a second position, and a third position, whereby the first position can control the light module 16, the second position can control the negative-ion generator 17, and the third position can control both of the light module 16 and the negative-ion generator 17.

Referring to FIG. 3, when the plug 14 provided at the base 11 is inserted into an electrical socket, the control switch 15 can be triggered to allow the light module 16 on the control circuit board to emit light, which in turn can pass through the light-passing body 21 fitted into the opening 12 of the base 11. The light module 16 can be provided with one LED of high brightness, as shown in FIG. 4, or a plurality of LEDs, as shown in FIG. 2. The negative-ion generator 17 can be provided at the rear side of the control circuit board (see FIG. 2) or at the front side of the control circuit board (see FIG. 4). The negative-ion generator 17 can be activated by the control switch 15 to generate negative ions, which are capable of cleaning the ambient air.

After the shade 31 is mounted on top of the base 11, the interior of the shade 31 can be furnished with a perfume bottle 33, which can be supplied with alcohol, aromatic compounds, water, essential oils, perfumes or balsams of natural plants, or any combinations of the foregoing. The light-passing body 21 can guide the light to go through the light-through holes of the shade 31, so that the lamp of the present invention can create a more distinctive atmosphere, as shown in FIG. 5. Furthermore, as shown in FIG. 6, a container 32 can be furnished in the interior of the shade 31 for holding fragrant wax. Also, the container 32 can be mounted with a cover assembly 34 including an outer slotted cover 341 and an inner slotted cover 342, wherein the outer slotted cover 341 is coaxially aligned with the inner slotted cover 342 and can be rotated relative to the inner slotted cover 342. By rotating the outer slotted cover 341, the slots of the covers 341, 342 can be closed or opened. In use, the plug 14 of the lamp structure can be inserted into an electrical socket 5. Then, the fragrant wax can be put in the container 32. Thereafter, the control switch 15 can be triggered to activate the light module 16 and the negative-ion generator 17, whereby the light emitting from the light module 16 can pass through the light-passing body and go out of the shade 31 via the light-through holes thereof. At the same time, the fragrant wax put in the container 32 can be evaporated naturally at room temperature. With this structure, the lamp of the present invention can be operated more safely. Furthermore, the negative-ion generator 17 can be activated by the control switch 15 to generate negative ions to purify the ambient air. Thus, the present invention can create a fragrant environment more safely to achieve the effect of relaxation, thereby removing the stress of a day.

Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention hereinafter claimed.
