Description

LED lamp with projection device

The invention relates to an LED lamp with a projection device, in particular to an LED lamp having a projection effect, which not only enables the lamp to be used as illumination, but also can produce a projection, and has the effect of situational illumination.

Lighting equipment is an indispensable daily necessities in daily life, changing people's lifestyles. Nowadays, in a general family or in public indoors, you can see the use of a variety of lighting equipment, such as: fluorescent lamps, lighting , table lamps, chandeliers, electric lights, etc., the inconvenience caused by dim can be improved through lighting equipment.

For different lighting equipment, the application uses are also different, for example: general fluorescent lamps, lighting lamps, table lamps, etc., which are used for general lighting, and some special-purpose lighting devices such as night lights, It is applied to the illumination provided by people when they fall asleep, and its luminous power is low, which is only for auxiliary use.

Conventional lamps or bulbs have the disadvantages of rapid heating and high power consumption, and the lamps will cause environmental problems after being discarded. Therefore, in recent years, Light Emitting Diodes (LEDs) have been developed as light-emitting diodes. Source technology.

LED lighting has been slowly accepted by humans as a lighting fixture, and in order to make LED lighting fixtures show more functions, to increase its practicality, it is an important issue for the industry.

The main object of the present invention is to provide an LED lamp with a projection device, which has the effect of projection for a more practical purpose.

In order to achieve the above-mentioned effects and purposes, the technical feature of the present invention includes a lamp holder, an LED lighting module and a projection device. The lamp holder is provided with a first illumination area and a second illumination area; the LED illumination mode The set is disposed on the first illumination area and the second illumination area of the lamp holder; and the projection device is disposed on the second illumination area of the lamp holder and located above the LED illumination module, by being located The LED lighting module on the second illumination zone of the lamp holder illuminates the projection device to produce a projector.

The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, so that the application of the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Please refer to FIG. 1 and FIG. 2 , which are schematic sectional views of an LED lamp with a projection device according to the present invention, which includes a lamp holder 10 , an LED illumination module 12 , a projection device 14 and a transmissive cover 16 . In the present embodiment, the lamp holder 10 is disposed on a rotating mechanism 18, and is provided with a first illumination area 20 and a second illumination area 22 on the same surface, which can be rotated by the rotation mechanism 18. The socket 10 can adjust the illumination positions of the first illumination zone 20 and the second illumination zone 22. The second illumination zone 22 of the socket 10 is formed with a stud 24 at a position.

The LED lighting module 12 includes a circuit board 26 and a plurality of LEDs 28 on the circuit board 26. The circuit board 26 is disposed on the first illumination area 20 and the second illumination area 22 of the socket 10, and is located at the The projections 24 of the two illumination zones 22 are formed with a perforation 29 for the posts 24 to pass through the perforations 29.

The projection device 14 is disposed on the second illumination area 22 of the socket 10 and located above the LED illumination module 12, and the LED illumination module 12 located on the second illumination area 22 of the socket 10 illuminates the projection device 14. And the projector is produced. The projection device 14 is provided with a first projection module 30 and a second projection module 32. The first projection module 30 is located above the LED lighting module 12, and the second projection module 32 is locked to the lamp holder 10. The protrusions 24 are adjacent to the first projection module 30, and a slot 36 for receiving a projection sheet 34 is formed between the first projection module 30 and the first projection module 30.

The lamp cover 16 is disposed on the first illumination area 12 of the lamp holder 10 and above the LED illumination module 12.

If yes, please refer to FIG. 3, the lamp holder 10 can be rotated by the rotation mechanism 18 to illuminate the first illumination area 20 and the second illumination area 22 upwards, when a situational slide 34 is placed in the slot 36. In the meantime, the image of the slide 34 can be projected onto the wall or the ceiling by the illumination of the LED illumination module 12 located in the second illumination zone 22, thereby presenting a situational illumination image.

While the present invention has been described above in the foregoing embodiments, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of patent protection shall be subject to the definition of the scope of the patent application attached to this specification.
