technical field

The utility model relates to the field of LED lighting lamps, in particular to an AC LED lighting module capable of changing the light emitting angle.

Background technique

LED is a semiconductor light-emitting diode. LED energy-saving lamps use high-brightness white light-emitting diodes as light sources. They have high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection; Bright, colorful, low loss, low energy consumption, green and environmental protection, suitable for lighting in families, shopping malls, banks, hospitals, hotels, restaurants and other public places.

With the development of economy and society and the continuous improvement of LED lighting technology, LED lighting fixtures known as "green lighting" have been more and more widely used in people's daily life. With the advantages of high speed, no pollution to the environment, and energy saving and power saving, it is gradually becoming the mainstream lighting fixtures today, and is widely used in commercial lighting, decorative lighting, road lighting, indoor and outdoor lighting and other lighting fields.

However, the structure and form of downlights are relatively single at present, which cannot meet the ever-increasing customer needs, and LED lamp products lack competitiveness.

Contents of utility model

The purpose of this utility model is to solve the above problems and provide an AC LED lighting module that can change the luminous angle, which can change different lens areas by simply replacing the lampshade, thereby changing the luminous angle of the lampshade. Due to the built-in drive circuit, no external The driver makes the design of lamps more flexible and changeable.

In order to achieve the above object, the utility model adopts the following technical solutions:

An AC LED lighting module that can change the luminous angle, including a housing, a circuit board, a light source, a driving circuit, a lampshade, and several brackets. The circuit board integrates the driving circuit and is fixed on the housing. The light source is several LED lamps The LED array composed of beads, several brackets are fixed on the edge of the housing, and the lampshade is made of transparent material and fixed on the brackets, and the feature is that the lampshade is provided with lens areas that can provide different lighting angles.

Further, the bracket is provided with mounting holes suitable for screws to pass through, and self-tapping screws can be used for easy installation.

Furthermore, the back of the housing is provided with thermally conductive double-sided adhesive, which can be conveniently pasted on a smoother plane for use.

Further, the back of the housing is provided with a heat dissipation groove, which can better dissipate heat and prolong the service life of the LED lamp bead.

Further, the heat dissipation grooves are circular or strip-shaped.

Further, the shape of the circuit board may be circular, square, rectangular or other shapes.

Further, the drive circuit integrated on the circuit board can be directly powered by commercial power.

The utility model adopts the above-mentioned structure, which can change different lens areas by simply replacing the lampshade, thereby changing the light-emitting angle of the lampshade, making the LED lighting more colorful, and because of the built-in drive circuit, no external driver is needed, making the design of the lamp more flexible Changeable, simple in structure, convenient and practical.
