Field of the Invention The present invention relates to a lighting fixture, and more particularly to an assembly using an LED concentrating assembly as a projection light source, which can be used for night lighting fixtures on both sides of a road. [Prior Art] Most of the street lamps used today are mercury street lamps, which are placed beside the road or on both sides of the street to provide night illumination. The use of mercury street lamps is extremely power-intensive. Under long-term use, the lamps produce high heat, which causes the bulbs and lamps to burn or blacken, thus shortening the service life of the bulbs and lamps, and even serious damage to the entire bulb or tube. It must be replaced. However, the luminaire is installed at a high place, which is not only inconvenient to replace, but also dangerous to replace at a high place. In addition, mercury itself is a harmful substance that can damage the brain and nervous system of the human body, and must be treated with care in recycling. Although the conventional mercury street lamp has high illumination capability, the above disadvantages can be replaced by light emitting diode (LED) lamps. The LED has the advantages of light weight, environmental protection, monochromatic light source, low power consumption and long life. It is the best source of light for replacing mercury lamps. Taiwan Patent No. 556800 describes a street lamp using an LED as a light source, and its structure is as shown in Fig. 1. The shape of the LED is a bulb shape, the luminous power is weak, and it is difficult to collect light. In addition, the number of side lamp holders is small, and the degree of deflection is limited. Therefore, the illumination distribution of 1260379 is not included in the illumination range, and the LED lamps have not yet met the requirements of the illumination lamps due to the illumination capability. In view of the above problems, the lighting capability of LED lamps needs to be actively developed. Therefore, it is necessary to use a L E D concentrating component as a light source instead of a mercury lamp with a low pollution and short life, and a lamp-shaped LED with a weak power. SUMMARY OF THE INVENTION The object of the present invention is to provide a nighttime lighting fixture with LED concentrating components as a light source applied to both sides of the road. Another object of the present invention is to provide a lamp holder that can change the light exiting direction of the LED concentrating assembly such that the light source emits light outward to control the illumination area. To achieve the above and other objects, the present invention provides an LED lighting fixture comprising: a plurality of LED concentrating components, a lamp holder, a lamp cover, a circuit board and a plurality of heat sinks. The lamp holder is a circular or elliptical disk-like body having a plurality of protrusions thereon, the protrusions being columnar and arranged in a concentric manner on the lamp holder. A heat sink is placed on the upper surface of the protrusion, and an LED concentrating assembly is placed on the heat sink. Since the LED generates a large amount of thermal energy when it emits light, the heat sink can transmit heat to prevent the LED from being lowered in efficiency due to overheating. According to a feature of the present invention, the upper surface of the partial protrusion is inclined, and the LED concentrating assembly can be deflected at an angle to project light outward, thereby achieving the effect of controlling the illumination area. According to a feature of the present invention, the circuit board is disposed on the lamp holder, and the position of 6 1260379% is opposite to the other side of the LED concentrating assembly, and the function is the connection - the wiring of the LED concentrating component, and the circuit on the circuit board Used to control the brightness of the LED. The lampshade is fixed on the lamp holder, and the light emitted by the LED concentrating component is emitted outward through the lampshade. The above and other objects, features, and advantages of the present invention will become more apparent and understood.

The half-angle of the luminous intensity distribution ranges from 5 degrees to 12 J degrees, and the distribution relationship between the luminous intensity and the angle is required. "Fig. 5" 'The LED concentrating unit 1〇1 efficiently projects most of the light directly in front. Please refer to "Fig. 2" and "Fig. 3" again. The lamp holder 1〇2 is a circular or elliptical disk-like object with a plurality of protrusions 1〇21, 1022. The protrusions 1021, 1〇 The 22-series columnar shape is arranged in a concentric circle on the lamp holder 1〇2. There are several protrusions 21, 1022 on the concentric circle, and the concentric circles are cut into several equal parts, and each protrusion is placed with a protrusion 1021. 1022. A heat sink 105 is placed on the upper surface of the protrusions 1021, 1〇22, and an LED concentrating unit 1〇1 is placed on the heat sink 105. Since the LED generates a large amount of thermal energy when it emits light, its heat sink 1〇5 transmits heat. The (four) LED reduces the luminous efficiency due to overheating. At the upper surface of the projection 1〇21 in the central portion of the socket 102, the light-emitting direction of the LED concentrating assembly 101 is parallel to the normal direction of the socket 彳〇2. The upper surface of the protrusion 1〇22 deviating from the central portion of the lamp holder is inclined, and the LED concentrating assembly 1〇1 can be yawed at an angle yaw angle at the connection center of the lamp holder to the LED concentrating assembly 1〇 In the radial direction of 1 , the angle between the light-emitting direction and the normal direction is offset outward in the radial direction, so that the light is obliquely directed outward, thereby achieving the effect of controlling the illumination area. Illustrated in "Figure 6", which is a schematic diagram of the present invention [ED lighting fixtures illuminate the ground. This figure illustrates the LED lighting fixture 10 projecting light into a circular illumination area 30. The tangential relationship Rypj of the radius 8 1260379 R of the illumination zone 30 and the height Η of the luminaire 10 from the ground can be obtained at an angle Θ. The angle α between the light-emitting direction of the inclined LED concentrating assembly 101 and the normal direction of the lamp holder 102 should be slightly smaller than the angle θ, and the highest intensity light of the LED concentrating assembly 101 can be put into the illumination range within 3 , to improve the light utilization rate. .
