Embodiment Construction

[0025] figure 1 A cross-sectional view of the LED retrofit lamp according to the present invention is shown. It can be seen from the figure that the LED retrofit lamp is composed of an LED lighting assembly and a lamp holder 1, wherein the LED lighting assembly has a printed circuit board 3 carrying an LED chip 4, The heat sink 2 is thermally connected to the printed circuit board 3, and the lamp cap 1 is fixedly connected to the other end of the heat sink 2, thereby constituting the LED retrofit lamp according to the present invention. It can further be seen from the figure that the bulb 5 is designed as a light guide with an inner surface 6 , an outer surface 7 as a light exit surface and an end surface 8 as a light incoupling surface for light from the LED chip 4 . The end surface 8 is supported on the printed circuit board 3 , and a receiving groove 11 is opened in the end surface 8 , and the LED chip 4 is accommodated in the receiving groove 11 . In this embodiment, the ...

Abstract

The invention relates to an LED lighting component. The LED lighting component comprises a printed circuit board (3) and a heat radiator (2), wherein the printed circuit board (3) is provided with an LED chip (4), the heat radiator (2) is connected with the printed circuit board (3) in a heat conduction manner. The LED lighting component further comprises a light guider designed into a foam shell (5). The light guider is provided with an inner surface (6), an outer surface (7) and an end face (8), wherein the outer surface (7) is used as a light emitting side, and the end face (8) is used as a light input coupling side of light from the LED chip (4), the inner surface (6) is structurized to form a reflection side (10) so that at least a part of light from the end face (8) is partially reflected and then emitted from the outer surface (7). Further, the invention relates to a modified LED lamp with the LED lighting component.

Description

technical field [0001] The invention relates to an LED lighting assembly. In addition, the present invention also relates to an LED retrofit lamp with the LED lighting assembly. Background technique [0002] As we all know, LED lighting has irreplaceable advantages, such as energy saving, ultra-low power consumption, close to 100% electro-optic power conversion, the same lighting efficiency is more than 80% energy-saving than traditional light sources, and its life is longer. In view of the above advantages, more and more people use LEDs as light sources, such as a large number of LED retrofit lamps appearing on the market. This LED retrofit lamp has the outline of a traditional light source such as an incandescent lamp or a lamp tube, so that it can be used as a light source to better adapt to an existing lighting system. [0003] A kind of LED retrofit lamp is disclosed in the prior art, and this LED retrofit lamp has: the lamp base that is used to connect with power sou...
