The electronic board is electronically connected with the driver, and the driver is electronically coupled with the base, wherein the peripheral sleeve is a colorful cover.

FIELD OF THE INVENTION

The present invention relates to a blub-type lamp structure which produces gradient visual colors.

BACKGROUND OF THE INVENTION

A conventional LED lamp contains a heat dissipation body in which a driver is fixed, an electronic board on which a plurality of LED elements are arranged, a base, and a peripheral sleeve. A first end of the heat dissipation body is connected with the base, and a second end of the heat dissipation body is coupled with the peripheral sleeve. The electronic board is electronically connected with the driver, and the driver is electronically coupled with the base.

The peripheral sleeve is a transparent cover made of plastic material, such that when each LED element emits white lights or yellow lights, the white or yellow lights project through the peripheral sleeve. Therefore, the conventional LED lamp cannot produce gradient visual colors.

To overcome such a problem, a conventional lampshade is disclosed in TW Publication No. M462831 and is connected with a lamp holder and a light emitting unit, wherein the lampshade includes a first cover, a second cover, and a connecting loop.

The first cover is in connection with the lamp holder, the connecting loop is coupled with the first cover and the second cover, such that the lampshade is assembled to project lights of different colors or transmittances through the first cover, the second cover, and the connecting loop.

However, the conventional lampshade is complicated and is manufactured at high cost. After the connecting loop is adhered with the first cover and the second cover, the first cover is adhered with the lamp holder, thus assembling the lampshade troublesomely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference toFIGS. 1 to 8, a bulb-type lamp structure10according to a preferred embodiment of the present invention comprises: a heat dissipation body11in which a driver111is fixed, an electronic board12on which plural illumining elements121are arranged, a base13, and a peripheral sleeve14. A first end of the heat dissipation body11is connected with the base13, and a second end of the heat dissipation body11is coupled with the peripheral sleeve14. The electronic board12is electronically connected with the driver111, the driver111is electronically coupled with the base13, and the base13is accommodated in a lamp holder (not shown), such that the plural illumining elements121emit lights for illumination.

It is to be noted that the peripheral sleeve14is a colorful cover and its outer periphery connects with an external rim of the heat dissipation body11so as to form an outer wall of the bulb-type lamp structure10.

The peripheral sleeve14is made of plastic material.

Alternatively, the peripheral sleeve14is made of glass material.

The bulb-type lamp structure10further comprises a transparent or nontransparent lid15made of plastic material, and the lid15is mounted on a bottom of the peripheral sleeve14to cover the electronic board12, wherein the lid15is flat (as shown inFIG. 1) or is curved (as illustrated inFIG. 6).

The heat dissipation body11includes a plurality of heat radiating fins112arranged around the outer wall thereof, and the plurality of heat radiating fins112are made of metal or plastic material.

The peripheral sleeve14is in any one of a column shape, a cylinder shape, an arc shape, a semi-circle shape, and a cone shape.

Each illumining element121is a white light-emitting diode or a yellow light-emitting diode.

The bulb-type lamp structure10further comprises a fixer16locked on the second end of the heat dissipation body11so as to connect with the electronic board12.

The peripheral sleeve14is adhered with the hollow fixer16.

The peripheral sleeve14includes plural locking pegs141arranged on one end thereof facing to the fixer16, and the fixer16includes plural orifices161defined on one end thereof so as to correspond to the plural pegs141, such that the plural pegs141of the peripheral sleeve14insert into the plural orifice161of the fixer16.

Alternatively, the peripheral sleeve14includes plural retaining tabs142arranged on the one end thereof facing to the fixer16, and the fixer16includes plural recesses162defined on the one end thereof so as to correspond to the plural retaining tabs142, such that the plural retaining tabs142of the peripheral sleeve14insert into the plural recesses162of the fixer16, as illustrated inFIG. 6.

In addition, a lampshade assembly20is configured to accommodate the bulb-type lamp structure10, as shown inFIG. 5.

Referring toFIGS. 1 to 8, the fixer13is fixed on the lamp holder (not shown) which electrically connects with a power source, such that the plural illumining elements121emit the lights.

Preferably, the peripheral sleeve14is the color cover and is made of plastic material or glass material, the bulb-type lamp structure10emits lights of different colors, wherein when said each illumining element121of the electronic board12is the white light-emitting diode, it emits white light, and colorful lights illuminate via the peripheral sleeve14. When said each illumining element121of the electronic board12is the yellow light-emitting diode, it emits yellow light, and the colorful lights illuminate via the peripheral sleeve14, thus producing visual effect of different colors by using the peripheral sleeve14, as shown inFIG. 4.

The bulb-type lamp structure10is accommodated in the lampshade assembly20, as illustrated inFIG. 5, and the peripheral sleeve14of the bulb-type lamp structure10is the colorful cover, so gradient visual colors produce. For example, when said each illumining element121is the white light-emitting diode and the peripheral sleeve14is purple, one part of the lampshade assembly20above the peripheral sleeve14illuminates purple lights, and the other part of the lampshade assembly20below the peripheral sleeve14illuminates white lights, as illustrated inFIG. 5, thus forming the visual effect of different colors.

Accordingly, the peripheral sleeve14and the bulb-type lamp structure10are combined together to produce lights of different colors by replacing various bulbs quickly.
