New description: [New technology field] and especially related to a ball This is a new type of lighting device. [Prior Art] With the continuous development and advancement of technology, the luminous efficiency of LED has not only surpassed the crane light bulb (efficiency is about 1G~2Glm/w), but it has also been over the fluorescent tube (efficiency is about 60~8〇). Above lm/w). In addition, the electronic components are increasingly required to be light and thin, so that the bulb type coffee gradually replaces the tungsten filament bulb, becoming a large and widely used lighting device. In general, the illumination angle of a conventional bulb type LED is often limited by the structure of the bulb lamp itself. In other words, the conventional bulb type LED has a limited light-emitting angle and cannot provide a relatively wide illumination range, thereby causing Conventional bulb type LEDs have limitations in lighting function.

Then it is converted into heat; when these heats are not properly discharged, it will cause the LED temperature to be too high. The conventional bulb type LED separately assembles the lamp holder and the heat sink seat, so that the heat resistance is too large, that is, the heat energy at the joint surface of the lamp holder and the heat sink seat

According to an embodiment of the present invention, a structure improvement of a wide-angle LED bulb is provided, which comprises a heat sink, an extension seat, a polygonal light source holder and at least one circuit board. The heat sink has a hollow. The extension seat protrudes outward from the heat sink seat along the direction of the central axis of the heat sink. The polygonal light source seat integrally protrudes from the other side of the extension seat relative to the heat sink, and the polygonal light source holder has a plurality of faces. The circuit board has a plurality of LEDs, and the LEDs are respectively disposed on each side of the polygonal light source holder. Wherein, the internal cavity of the polygonal light source holder and the extension seat forms a hollow, which communicates with the hollow. Further, in other embodiments of the technical aspect, a plurality of heat conducting ribs may be further included, which are disposed at the hollow. Further, the aforementioned heat conducting ribs may be perpendicular to the respective faces of the heat sink. Then, the extension seat can be clipped to a pure angle with the horizontal plane φ. In addition, the extension seat can be composed of a plurality of slopes. Alternatively, the extension may consist of a curved surface. The shape of the polygonal light source holder can be a hexagonal column shape. In addition, the circuit board can be a flexible high thermal conductivity circuit board. Furthermore, the circuit board can be seamlessly attached to the polygonal light source holder. Finally, a reflective layer may be further included on the surface of the extension to enhance the light extraction efficiency of the LED. Therefore, the above embodiments solve the problem that the illumination function is limited by the extension seat allowing the LED on the polygon light source holder to have the maximum light exit angle. On the other hand, the design of the heat sink, the extension seat and the polygonal light source seat make the LED have better heat conduction and heat dissipation effect, and the 4 M429032 also solves the problem that the conventional bulb type LED heat dissipation is not effective. In addition, the extension of the extension seat and the polygonal light source holder are hollowed out, which greatly reduces the overall weight. [Embodiment] FIG. 1 is a perspective view showing an improved structure of a wide-angle LED bulb according to an embodiment of the present technology. As shown in Fig. i, the wide-angle LED bulb structure improvement 100 includes a heat sink 110, an extension seat 12A, a polygonal light source holder 130, and at least one circuit board 14A. • Figure 2 shows an improved decomposition diagram of the wide-angle LED bulb lamp of Figure 1. Fig. 3 is a cross-sectional view showing the improved structure of the wide-angle LED bulb of Fig. 1 along line segment 1-1. As shown in Figs. 2 and 3, the heat sink 11 has a hollow portion 11 - the hollow portion U1 f is used to mount the actuator. The extension seat 120 protrudes outward from the heat sink seat U0 in the direction of the central axis of the heat sink 110. The polygon light source holder 13G is integrally connected to the other side of the heat sink 110 from the extension seat 12 and protrudes outward. The other polygon light source base m has a plurality of faces 131, and the polygon light source holder 130 of the present embodiment is presented. Hexagonal column shape. In particular, the heat sink 11〇, the extension seat 12〇, and the polygonal light source holder (10) of the present embodiment are formed by body-molding, and since there is no joint gap between the respective bodies, the heat conduction effect is excellent, so there is no conventional bulb. The type of coffee has the problem of heat resistance that generally makes the heat transfer efficiency ineffective. The circuit board 140 has a plurality of LEDs 141, and the coffee makers (4) respectively correspond to the respective faces (3) of the polygonal optical job 13G. The circuit board 140 of the present embodiment is a soft high thermal conductive circuit board, which can be seamlessly attached after being bent. More 5 M429032 edge light source holder 130. Wherein, each surface 131 of the polygonal light source holder 130 may have more than one LED 141'. The number of LEDs 141 may be set according to actual needs. Furthermore, the main function of the extension holder 12 is to raise the height of the polygonal light source holder 130 such that the polygonal light source holder 3 is located close to the center of the LED bulb; thus, the light source disposed on the side LED 141 It can be diffused to an angle below the horizontal plane L without being blocked by other structures to increase the overall exit angle. Moreover, with this design, the present embodiment can achieve a large angle of light like a conventional bulb without any optical control element. In order to cooperate with the hexagonal column light source holder, the extension seat 丨2〇 of the present embodiment has a tapered shape surrounded by six inclined surfaces 121, and each inclined surface pi and the horizontal plane L have an obtuse angle Θ 'This design is intended to prevent the extension seat 12〇 from blocking The diffused light source to the side LED 141. However, the extension seat 12〇 may also be composed of a curved surface. The design concept is the same as the previous design, as long as it does not block the diffused light source of the side LED 141, no matter what shape does not deviate from the central concept of the design. Similarly, although the polygonal light source holder 130 of the present embodiment has a six φ corner post, its shape can be adjusted according to actual conditions. In addition to the special design of the heat sink 110, the extension base 120 and the polygonal light source holder 130, the polygonal light source holder 13〇 and the extension seat 120 of the present embodiment are hollowed out to form a hollow portion 150, and the hollow portion 150 and the heat dissipation portion The hollow portion 111 of the seat 110 is connected to each other, and has the effect of eliminating light overall weight and saving cost; on the other hand, the thermal energy emitted by the LED 141 on the polygonal light source holder 130 can transfer thermal energy from the polygonal light source holder 130 to the heat sink 11 through heat conduction. 〇, for the heat exchange of hot and cold air, so as to further improve the heat dissipation effect of the heat sink 11 〇 overall.
