Abstract

The invention provides an LED flat bulb lamp. The flat bulb lamp comprises a light permeable cover, a circuit board, a heat radiating base, a driving power source, a plastic shell and a lamp holder from top to bottom. The upper light permeable surface of the light permeable cover is an inner concave lens surface. The side light emergent surface of the light permeable cover is a cambered surface. The lower portion of the interior of the side light emergent surface is provided with internal threads. A clamping mount is arranged at the upper end of the threads. The light permeable cover is in threaded connection with the heat radiating base. The circuit board is arranged on the top above the heat radiating base and is fastened between the heat radiating base and the light permeable cover through the clamping mount. A plurality of luminous chips are arranged on the circuit board. The driving power source is arranged in the plastic shell. According to the illuminating features of the LED chips, light rays are controlled to pass through a front light permeable surface forwards and the side light emergent surface sideward, so 180-degree planar illuminating of the flat bulb lamp is achieved, the defect that illuminating angles of light sources of other bulbs are too large is overcome, and the requirements of some lamps and some occasions are met.

Description

[0001] technical field [0002] The invention relates to an LED bulb, in particular to an LED flat bulb. [0003] Background technique [0004] At present, the existing LED bulbs on the market, such as spherical lamps, pointed bulb lamps, and other LED bulb light sources, all emit light at a three-dimensional angle of about 360 degrees; LED bulbs also include LED spotlights, and their light angles are generally Less than 90 degrees. The existing bulb-type light source has certain defects during use, and also has a certain amount of waste of luminous flux, and can not meet the use requirements of some lamps and certain occasions. Therefore, a light bulb with a new structure is needed to make full use of the characteristics of LED light emission, so that the light emitting surface is about 180 degrees, which greatly improves the practical value of light to meet the needs of different lamps and different occasions. [0005] Contents of the invention [0006] In order to o...
