於照明光源及.裝飾光源。 [0003] 配合參閱第一圖，為習知之發光二極體燈泡之側視圖。 該發光二極體燈泡80包含一座體82、一光源模組84、一 燈罩86及一導電接頭88。該座體82之外壁面環繞排列有 複數之散熱片820，藉以增加散熱面積。 [0004] 該光源模組84設置於該座體82之一侧並包含一電路板840 及複數個發光二極體842，該等發光二極體842設置於該

The LED bulb 80 includes a body 82, a light source module 84, a lamp cover 86 and a conductive joint 88. A plurality of fins 820 are arranged around the outer wall of the base 82 to increase the heat dissipation area. The light source module 84 is disposed on one side of the base 82 and includes a circuit board 840 and a plurality of light emitting diodes 842 disposed on the circuit board 840 and electrically connected thereto. Circuit board 840. The lamp cover 86 covers the light source module 84 such that the light source module 84 is located between the base 82 and the lamp cover 86. The conductive connector 88 is connected to the side of the body 82 opposite to the light source module 84. The conductive connector 88 is electrically connected to the light source module 84 and is connected to the light source diode 84 for providing illumination of the light emitting diodes. External outlet for 842 power (not shown). [0005] However, the light-emitting diode 842 is a directional light source, so the light emitted by the light-emitting diodes 842 can only emit light toward the front, and the corresponding light intensity distribution is as shown in the second figure, wherein L Indicates that the light-emitting diode bulb 80 10120301# single number should be 01 page 3 / total 31 pages 1013181702-0 M436134 _, May 15, 2011 shuttle color changing page light distribution curve. As can be seen from the second figure, the light-emitting diode bulb 80 cannot meet the light-emitting requirements of a non-directional light source such as a general incandescent light bulb, so that the user is less willing to use the light-emitting diode bulb 80. [New Content] [0006] In view of the prior art, it is an object of the present invention to provide a lamp cover that is disposed on a light exiting side of a light bulb for expanding an exit angle of light emitted by the light bulb.

[0009] For another purpose of the present invention, the present invention provides a light-emitting device comprising a light source module and a light cover, the light source module comprising a body, a light-emitting unit and a conductive joint, the seat body The first accommodating portion and the second accommodating portion are opposite to the first accommodating portion. The illuminating unit is disposed on the first accommodating portion, and the conductive joint is clamped to the second accommodating portion. The light source cover is disposed between the base body and the lamp cover, and the light cover comprises a light-transmitting cover body and a reflector. The inner surface of one of the light-transmissive cover bodies has a central portion Connecting mechanism; the reflecting member 1013181702-0. Single number A0101 Page 4 of 31 M436134 The correction of the page is substantially tapered and has a plurality of openings thereon, and the reflecting member is connected thereto. The connecting mechanism is located on the light source module with a predetermined distance. [Embodiment] [0010] Referring to the third, fourth, and fifth figures, respectively, a perspective exploded view, a combined view, and a cross-sectional view of the light-emitting device of the first embodiment are created. In the embodiment, the illuminating device 1 is exemplified by an A19 bulb, and the actual implementation is not limited thereto.
