Embodiment Construction

[0048] Please also refer to Figure 1A and Figure 1B , respectively show an exploded view and an assembled view of a light emitting device according to an embodiment of the present invention. The light emitting device 100 includes a base 110 , a light source 120 , a driver 130 , a heat sink 140 and a flexible substrate 150 .

[0049] The base 110 may be made of metal to dissipate heat from the light source 120 . Alternatively, the base 110 can also be made of ceramic material.

[0050] The light source 120 includes a plurality of light emitting units disposed on the flexible substrate 150 . The light source 120 generally refers to an active or passive element capable of emitting electromagnetic radiation, such as a light emitting diode.

[0051] The driver 130 is disposed on the upper surface 110 u of the base 110 , and is electrically connected to the flexible substrate 150 to drive the light source 120 disposed on the flexible substrate 150 to emit light or not to emit l...

Abstract

A light emitting device (100) comprising a base (110), a driver (130), a heat sink (140), a flexible substrate (150) and a light source (120) is provided. The driver (130) is disposed on the base (110). The heat sink (140) is disposed on the base (110) and has a lateral surface surrounding the driver (130). The flexible substrate (150) surrounds the lateral surface of the heat sink (140) and is disposed thereon. The light source (120) is disposed on the flexible substrate (150) for emitting a light in multi-directions.

Description

technical field [0001] The invention relates to a light emitting device, and in particular to a light emitting device capable of emitting light in a side direction. Background technique [0002] A traditional LED light bulb includes a base, a printed circuit board, and LEDs, wherein a printed circuit board (PCB) is laid flat on the base, and the LEDs are arranged on the circuit board to make the LEDs emit light upwards. [0003] However, since the printed circuit board can only be placed on the base in a flat manner, the light emission direction and angle of the LED are limited. Contents of the invention [0004] The object of the present invention is to provide a light-emitting device, the flexible substrate of which has flexibility, so that the light emitting direction of the light source disposed on it can be elastically designed. [0005] To achieve the above purpose, according to an embodiment of the present invention, a light emitting device is provided. The light ...
