The invention provides an external LED (light-emitting diode) bulb lamp which comprises an upper locking pad, a lower locking pad, an upper heat dissipation body, a heat dissipation body bracket, a lower heat dissipation body, flexible LED components, a heat dissipation sleeve, a driving power supply, a lamp base and a lamp cap, wherein the upper heat dissipation body and the lower heat dissipation body are buckled into an integral ball, the heat dissipation body bracket is covered inside the upper heat dissipation body and the lower heat dissipation body, each of the flexible LED components is composed of a flexible baseplate and an LED which is installed on the flexible baseplate, each of the flexible LED components is in the shape of blades in parallel arrangement, the lower sides of the flexible LED components are interconnected and rolled into a circle to form a star structure, the bottom part of each of the flexible baseplates is connected with the bottom surface of the heat dissipation body bracket, the top end of each of the flexible baseplates is connected with lower locking pad, and each of the flexible baseplates of the corresponding flexible LED components is rolled upwards along the concave surface of the lower heat dissipation body and the upper heat dissipation body. The bulb lamp adopts the pattern of the external LED, so that the light emitting angle is close to 360 degrees; furthermore, each of the flexible LED baseplates clings closely to the concave surface of the upper heat dissipation body and the lower heat dissipation body, so as to provide a good heat dissipation effect and prolong service life of the LED lamp.
Description
technical field [0001] The application of the present invention relates to an LED external bulb lamp, which belongs to the technical field of LED lighting equipment. Background technique [0002] At present, there are many types of LED bulb lamps, but because LEDs are semiconductor components, they will generate heat when they work, and they must be dissipated in time to work, otherwise the LEDs will overheat and burn out quickly, and even if they do not burn out, the luminous efficiency will be greatly reduced. Therefore, the LED bulb lamp made of LED basically adopts the structure of metal heat sink and hemispherical light-transmitting cover, and the LED plane is distributed at the connection plane between the metal heat sink and the hemispherical light-transmitting cover. [0003] Due to the characteristics of the LED package structure, the light-emitting surface generally has only one side, and the light-emitting angle does not exceed 150 degrees. Therefore, the light e...
