Description

LED lamp structure

The invention relates to an LED lamp structure; in particular, to an LED lamp structure in which a light source is diffused from a side edge of a lamp by a central cover body, so that the LED lamp structure has more practical value of illumination, appearance and situational effect.

Since ancient times, the use of traditional candles has been used from the simple lighting function, and has continued to be used in home decoration, celebrations, ceremonies or atmospheres. Its use, function and use have become more and more popular. The wider it is, it becomes one of the important items in daily life; however, when the traditional candle is ignited, it will produce a flame relationship. If it is used carelessly, it may cause accidents such as fire or burns. Otherwise, the candle is used outdoors. It is also often difficult to ignite or easily extinguish due to the relationship of air flow; moreover, carbon dioxide and other exhaust gases generated by the ignition of candles will cause air pollution, which will affect the air quality and the environment that is easily smoked (such as walls or ceilings). It does not have the implementation of environmental protection and the improvement of the quality of healthy living.

With the advancement of technology, the existing general lamps, in addition to high-brightness lighting fixtures in different situations, also have small candlelights instead of traditional candles, the purpose of which is to provide users with the same at night. A soft light source that is not glaring like a candlelight creates a different atmosphere that not only saves power, but also softly shimmers to make people feel different situations to convert emotions.

LED lamps are widely used in display and lighting applications because of their high brightness, high stability, long life, and low power consumption. The LED lamp generally comprises a lamp holder and a lamp body, the lamp body is provided with components such as an LED light-emitting chip and a lamp cover, and the lamp holder is provided with an LED driving device for driving the LED light-emitting chip to emit light; however, since the light source of the LED lamp has directivity The projection angle is small, so the general candlelight (candle) lamp usually does not have good illumination brightness, and the candlelight (candle) lamp power is small, so the LED lamp structure is also weak for the heat dissipation design, thereby affecting The service life, so how to balance the lighting brightness and heat dissipation efficiency of LED lamps, is an important technical issue for LED lamps.

In view of the characteristics of the conventional LED lamp structure, the present invention provides an LED lamp structure different from the conventional structure, the purpose of which is to enable the LED lamp to provide different situational illumination characteristics and at the same time have better heat dissipation efficiency; The LED lamp structure comprises a main lamp body, a connecting unit and a central cover body joined together, wherein the main lamp body comprises a heat dissipating unit, a light emitting unit and a driving unit, and the main lamp body is mounted and engaged with the central cover body and passes through the central cover body The hollow pipe is directly connected to the connecting unit; the connecting unit is joined to the other end of the central cover, and can be freely disassembled and assembled to change different connectors, and the main lamp body can be freely disassembled and assembled to simplify the maintenance of the LED lamp. program.

Figure 3 is a cross-sectional view showing the structure of the LED lamp of the present invention.

According to the structure of the LED lamp of the present invention, please refer to FIG. 1 first, which is a perspective view of the structure of the LED lamp of the present invention.

In the LED lamp structure of the present invention, the appearance assembly comprises a main lamp body 10, a central cover body 20 and a connecting unit 30, and the main lamp body 10 is connected to The top end of the central cover 20 is used to generate a light source and is sent out through the central cover 20, and the assembled form of the main lamp body 10 and the central cover 20 is more suitable for snapping, rotating pressing and fitting. Optionally, the main lamp body 10 is fixed on the central cover 20, and the connecting unit 30 is connected to the tail end of the central cover 20 for connecting an external lamp holder to receive electric power, and is transmitted through the central cover 20 and the main lamp body. 10 is electrically connected to transfer power to the main lamp body 10.

Next, please refer to FIG. 2, which is an exploded view of the structure of the LED lamp of the present invention; the main lamp body 10 of the LED lamp structure of the present invention can be provided with an accommodating space in the outer casing 11 , and the heat dissipating unit 13 can be designed as The insert fin is inserted into the accommodating space 11 and integrated with the housing 11 , and the driving unit 20 is inserted and embedded in the accommodating space and surrounded by the fins of the heat dissipating unit 13 . The heat dissipation effect can be created for the driving unit, and the fixing unit 14 can be used for fixing the driving unit; the light emitting unit 12 is used for absorbing the heat dissipation unit 13 and transmitting the heat energy generated during the lighting to the heat dissipation unit 13. And receiving the working power source transmitted by the driving unit to generate the light source, the connecting unit 30 is disposed at the end of the central cover 20 and is provided with a joint device, and the housing 11 of the main lamp body 10 is provided with a convection hole 111, which can be used for The heat source generated by the operation of the main lamp body 10 is dissipated by the convection effect, resulting in a good heat dissipation effect.
