Embodiment Construction
[0020] see figure 1 , providing a flat LED light bulb 101, including a saucer-shaped lamp body 20 and a lamp cap 30 detachably connected to the lamp body 20. In this embodiment, the lamp cap 30 is provided with a screw joint 301 with external threads The top of the screw connector 301 is provided with a first electrical contact 302, and the outer thread around the screw connector 301 is a second electrical contact, and the first and second electrical contacts are the positive and negative poles of the LED light bulb 101. input terminal. The LED light bulb 101 is assembled to a lamp holder (not shown in the figure) of the lighting device through the lamp cap 30 , so that the external high-voltage AC power can be input into the LED light bulb 101 . In this embodiment, the lamp cap 30 is an E27 or E26 standard lamp cap.
[0021] see figure 2 , the lamp cap 30 and the lamp body 20 are fixed together by a plurality of screws 41 . In other embodiments, the lamp cap 30 and the l...

The invention relates to an LED (Light Emitting Diode) bulb, which comprises a saucer-shaped lamp body and a lamp cap which is detachably connected with the lamp body. The lamp body comprises a shade body, a cover body, an LED lamp panel, LED particles, an LED driver and a fixing device. The fixing device is used for compactly assembling the shade body, the LED driver and the LED lamp panel together. The LED driver is respectively and electrically connected with the lamp cap and the LED lamp panel to transform an external high-voltage alternating-current power supply into a low-voltage direct-current power supply which is needed by the LED particles, so as to directly drive the LED particles to emit light. The fixing device comprises a first installation part. The LED lamp panel is installed on the external side surface of the first installation part, so as to enable the LED particles to face to the side surface of the fixing device and to emit light rays towards the shade body. The internal surface of the shade body is a reflecting surface. Light rays which are incident upon the internal surface of the shade body are reflected onto the cover body through the shade body, penetrate through the cover body and are emitted to the external world. The flat LED bulb provided by the invention is provided with the replaceable lamp cap, thus being capable of being widely used in the fields of household bulbs, decorative bulbs and the like.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a flat LED light bulb using a light emitting diode (LED). Background technique [0002] In recent years, LED has gradually been used in lighting equipment as a new light source technology. Converting all existing incandescent bulbs to LED light sources will undoubtedly greatly promote energy conservation. The technical advantages of LED light sources are obvious, but from the perspective of lamp holders, existing incandescent lamps have been used in society for many years, and their lamp holders are quite popular. Discarding the lamp holder will cause a great waste of material resources. Therefore, how to replace the traditional incandescent light bulb with an LED light source on the existing incandescent lamp socket has become an urgent problem to be solved in the field of lighting technology. In addition, how to make LED lamps compact in structure and wider in application ra...
