Field of the Invention The present invention relates to a light-emitting diode lamp, and more particularly to a light-emitting diode lamp for outdoor lighting. [Prior Art] As a new generation of light source, the light-emitting one-pole light source does not make a large-scale replacement of the conventional incandescent lamp, but it has the advantages of long working life, energy saving, environmental protection, etc., and is generally favored by the market. At present, the module consisting of a light-emitting diode has a high-power, high-brightness light source, so it will widely replace the conventional light sources such as incandescent lamps, and become the main energy-saving and environmental protection theme. light source. However, as the power and brightness of the LED or its module increase, the amount of heat generated is also increased. If the heating problem of the LED is not properly solved, the operation of the LED lamp is completed. Life expectancy will be severely affected. Therefore, a heat sink is usually mounted on the LED module to perform the administrative heat, and the LED module is horizontally placed on the bottom of the heat sink to become a planar light source. Due to the single illumination direction of the planar light source, the illumination area of the luminaire is limited, and in many cases it is difficult to satisfy the user. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a light-emitting diode lamp that can convert a planar light source into a stereo light source to increase the illumination area. A light-emitting diode lamp includes a lamp holder, a heat sink disposed on the lamp holder, and a light-emitting diode module attached to the bottom of the heat sink, wherein the light-emitting one-pole assembly is housed in the lamp holder a reflector is placed in the lamp holder and directed toward the hair source 200928200. The light diode module reflects the light emitted by the light emitting diode module to the outside of the lamp holder, and the reflector in the lamp makes the planar light emitting diode The module produces a three-dimensional light source effect, which can be increased without increasing the number of light-emitting diodes, thereby increasing the illumination area of the light-emitting diode lamp, and at the same time satisfying the user's multiple angles of illumination. [Embodiment] Please refer to FIG. 3A. The light-emitting diode lamp of the present invention comprises a lamp holder 10, a heat sink 20 disposed on the lamp holder 10, and a light-emitting one attached to the bottom surface of the heat sink 2 The polar body module 30 and the lamp cover 々ο, the reflector 50 and the circuit board 60 housed in the lamp holder 1〇. The light emitted by the LED module 3 can be reflected out of the lamp cover 4 by the reflector 50. The base 10 includes a base 12, a top frame 16 and four support bases 12 and a post 14 of the top frame 16. The base portion 12 is generally rectangular in shape with four sides extending upwardly to a certain height to form four side walls (not shown). A through hole 121 (see Fig. 3) is provided in the center of the base portion 12, and a fixing hole 122 is formed in the middle portion of the base portion 12 at four intermediate sides thereof. The four legs extend obliquely upward and outward from the four corners of the base 12 and are respectively connected to the four corners of the top frame 16. The area of the top frame 16 is larger than the area of the base 12. The top frame 16 is provided with a plurality of first mounting holes 161. The base 12, the post 14 and the top frame 16 together define an accommodating space (not shown) for accommodating the circuit board 60, the reflector 50, the lamp cover 4, and the LED module. Each of the two adjacent pillars 14 and the corresponding portion of the base portion 12 and the top frame 16 together form a window 142, and the light emitted by the LED module 30 can pass through the window 142. 〇 〇 outside. The base portion 12 of the socket 10 extends downwardly at its central position to form a connecting portion 18 for securely attaching the LED luminaire to a light pole (not shown). The heat sink 20 is disposed on the top frame 16 of the socket 10 and includes a substrate 21 and a plurality of heat dissipation fins 22 disposed on the upper surface of the substrate 21. The height of the heat dissipating fins 22 at the central position of the substrate 21 is the same, and the heights of the fins 22 on both sides are gradually reduced to make the fins 22 integrally form a terrace. Corresponding to the first mounting holes 161 on the dome frame 16, a plurality of second mounting holes 211 are formed on the respective sides of the substrate 21 of the heat sink 2 for the fixing members (not shown) to pass through the heat sink. 20 is fixed to the top frame 16. The light-emitting diode module 30 includes a rectangular substrate and light-emitting diodes 32 arranged in a matrix on the substrate. The light emitting diode module 3 is attached to the lower surface of the substrate 21 of the heat sink 20. A plurality of screw holes are further provided in the LED module for the screws (not shown) to further pass the LED module 30 to the substrate 21 of the heat sink 20.电路 The circuit board 60 is placed on the base 12 of the lamp holder. The circuit board 6 is electrically connected to the LED module 3 via a wire (not shown) to provide power and other control signals to the LED module 30. The wires on the circuit board 6 can be connected to the external power source through the through holes 121 in the base 12. The reflector 50 is placed over the circuit board 6A. In the present embodiment, the reflector 50 has a hollow conical shape with its top end facing the bottom end of the LED module toward the circuit board 60. Four legs 51 are extended downward from the lower end of the inner wall of the reflector 50, and the four legs 51 are inserted into the fixing holes 122 of the base 12 and the reflector 5 is fixed to the base by a fixing member (not shown). Η上. 8 200928200 The outer surface of the reflector 50 is coated with a layer of reflective material, thus emitting a diode. The light emitted by the module 30 can be reflected from the outer surface of the reflector 5 to the outside of the lamp holder. It will be appreciated that the reflector 5() may have a different shape in different embodiments. For example, the reflector 5G can be a polyhedral shape, and the top end thereof also faces the light-emitting body module 3G. The light emitted from the LED module 3 can be reflected at different angles to the lamp holder. outer. The lampshade 40 is similar in appearance to the lamp holder 10 so as to be housed in the lamp holder 10 for protecting various components such as the reflector 5, etc. placed in the lamp holder 1〇. The lampshade 40 has four sides, and the upper and lower ends form an opening, and the upper end opening is larger than the lower jaw opening. Each side of the lampshade 4 封闭 closes each of the windows 142 of the socket 1 ′ while the edges of the two adjacent sides abut against the struts. The lower end of the lamp cover 40 abuts against the base 12 of the socket 1 , and the upper end of the lamp cover 4 抵 abuts against the lower surface of the substrate 21 of the heat sink 2 . In order to make the upper and lower ends of the lamp cover 40 better adhere to the substrate 12 of the heat sink 2 and the base 12 of the socket, the corresponding positions of the base portion 12 of the substrate 21f are respectively formed into a receiving lamp cover 4 The lower end of the receiving slot 21 has a heart 124. A waterproof gasket 70 is disposed in each of the accommodating grooves 124, 214 (four), so that rainwater or the like can be prevented from entering the lamp holder 10 from the upper and lower ends of the lamp cover 4G when the illuminating body lamp is used outdoors. This further protects the components in the lamp holder 1 from damage and prolongs the service life of the LED lamp. The lampshade 4 can be made of a transparent or translucent material such as glass or the like so that light reflected from the reflector 50 can pass through the lamp cover 4〇. When the lampshade is made of a translucent material, the light emitted from the LED module can not be directly seen outside the light-emitting diode lamp. The light emitted by the LED module 30 can become more 9 200928200 - soft, avoiding generation Glare effect. When assembling the LED lamp, the circuit board 60 is first placed on the base 12 of the lamp holder 1 , and then the reflector 5 is placed on the circuit board 6 并 and fixed on the base 12 of the lamp holder 10 . Place the lamp cover 4〇 in the lamp holder 1〇. Finally, after the LED module 30 is mounted on the heat sink, the crucible 20 is mounted on the top frame 16 of the lamp holder 10. ... ° Please refer to FIG. 3 again. When the LED device is in operation, the LED module 30 is powered by the circuit board 60 to generate light. As indicated by the arrow in Figure 3, a portion of the light can be directed downwardly through the lamp cover 4 to the outside of the lamp holder 10. Another part of the light is projected onto the reflector 5, and is reflected by the reflector 50 to reach the lamp holder 10. Since the surface of the reflector 5 相对 is inclined relative to the LED module 30, the light reflected by the reflector 5 不同 at different portions of the vertical section can be projected to the lamp holder 1 不同 at different angles. The illumination angle of the light emitted by the polar body module 30 increases under the same vertical section, thereby obtaining a larger illumination area. At the same time, since the reflector ❾50 has a three-dimensional conical shape, the light reflected by different parts of the reflector 5〇 under the same horizontal section can be radiated outward along the axial direction of the reflector 50, and multiple illumination angles can be obtained in the horizontal direction. To meet the lighting needs of users with multiple angles. Therefore, the light-emitting diode lamp adopts the planar light-emitting diode module 30, and can still obtain a three-dimensional light source with a large illumination angle. Compared with the conventional light-emitting diode lamp, the light-emitting diode lamp of the present invention has a larger irradiation area before the same light-emitting diode module is used. The heat sink 20 is disposed on the LED module 3, and the heat emitting diode module 30 can be dissipated to ensure that the LED module 3 is in the normal operating temperature range of 200928200. The heat sink 2〇 has a simple structure, and the effect reduces the cost of the light-emitting diode lamp. In addition, the heat-dissipating system is built on the top of the M-light body lamp, and at the same time, it can protect the various parts of the lamp holder Sichuan, and prevent rain and other debris from entering the lamp holder 1Q. 70 Ο In summary, the invention conforms to the patent requirements of the invention, and is proposed according to law.
