Description of the invention: [Technical field of invention] A luminaire refers to an appliance that can transmit light and change the distribution of light. The illuminating source and the components required to protect the light source and the line accessories used for the power connection, lighting fixtures are required. It is an indispensable tool in general life. With the advancement of technology and the improvement of living functions, good lighting design is to display the function and purpose of the lighting facilities in the most appropriate way, and create an atmosphere with a lighting environment. The types of lamps are very diverse. For example: home lighting 'industrial lighting, commercial lighting, road lighting, landscape lighting and special lighting. The lamps are the first to use incandescent light bulbs, and the development of technology has progressed to fluorescent tubes, energy-saving lamps, halogen lamps. , tungsten light and ^^ special materials lighting and so on. [Prior Art] Illumination refers to 'using various light sources (such as light bulbs, tubes or light-emitting diodes) to illuminate a special space, object or environment. 'Modern artificial lighting is mainly used in electric lighting devices and used in the past. It is a gas lamp (gas lamp), a candle, an oil lamp, etc. The lamp is mainly used as a source of illumination for the general life when the sun goes down at night. The main indoor lighting can be divided into the ceiling (four) and the chandelier. Putting on the table and watching the secrets of the f, and then taking advantage of the development of science and technology of the times, the function of the lamps is not only the lighting, but also the development of other different functions such as the entertainment lanterns, which are still thin, the police are pure red. New Zealand, a flashlight that can be used for money, etc. In recent years, due to the Weiyuan crisis and the awareness of environmental protection, the pursuit of high efficiency and high color rendering is the direction of light source development. Kailaiguang·Qingyuan and LED are the focus of 201241353 technology development, LED (Light: LED) -Emitting Diode (LED), when the forward voltage is applied, the light-emitting diode can emit monochromatic and discontinuous light, which is a kind of electroluminescence effect, which has high efficiency for converting electrical energy into light energy, and is suitable. Under the heat dissipation and application environment, the advantages of traditional light sources such as the use time of 35, 000~50, 000 hours, and not easy to break can not be compared. When the chemical composition of the semiconductor material used is changed, the light emitting diode can be emitted. Near-ultraviolet, visible or infrared light 'LED' as an alternative to incandescent and fluorescent lamps, known as solid-state lighting (SSL) 'In recent years, the efficiency of LEDs has increased rapidly: the current high-power white light average output is 60~80 Lumens per watt (im/w) 'The long life of LEDs makes solid-state lighting very attractive. The change of the moon phase in astronomy is because the moon seen from the earth is illuminated by the sun. When the moon rotates around the earth, the relative position between the sun, the earth and the moon constantly changes. The moon phase is the moon. The phase 'is the way the moon looks when the moon appears in different positions on the road. '3 The bright hair is because the anti-sunshine shouts brightly, and the moon is directly captured by the sun to reflect the light. Therefore, the moon seen from different Xiaodu will present different reflections. The moon phase is not caused by the earth covering the sun (this is the moon (6), but because we can only see the sun on the moon. To that - half of the part of the 'the shadow is the moon's own dark side. The full moon is when the earth is between the moon and the sun, you can see the whole moon is reflected by the sun directly, the new moon is when When the moon is between the earth and the sun, we can only see the part of the ball that is not illuminated by the sun. When the string is connected to the sun and the moon at right angles, we are just right. You can see that the moon is half-fired by the sun. Because the lunar calendar is set according to the cycle of the moon, the moon is around the earth for a week, so the different lunar dates, the corresponding ribs are different, the rib changes The order is the new moon (initial-) (four) moon, eyebrow month _ 3rd ~ 5th running fine 1 ~ tear 201241353 see, the first quarter (Lunar 7th ~ 8th) 50% of the right side of the moon visible, Ying convex month (Numerical ι 〇号~12号) 51~99% of the right side of the moon is visible, and the full moon (Lunar No.14~17) can be seen throughout the moon, and then becomes the bulging month (Lunar 18th~20th). The left side of the moon is 51~99% visible. The lower chord month (Lunar No. 22~23) 50% visible on the left side of the moon, and the residual moon (Lunar No. 29~30) is visible from 1 to 49% of the left side of the moon. The mechanical devices are composed of simple mechanical combinations, including levers. Gears, belts, runners, cams, cranks and springs, etc., which are often connected to each other as complex devices. In the mechanical transmission principle, gears are wheel-shaped mechanical parts that rely on the meshing of the teeth to transmit torque. Simple Distinguish as parallel shaft gears, intersecting shaft teeth And the staggered shaft gear, the general gear material can include: plastic injection gear, medium carbon steel, alloy steel, aluminum or copper alloy, and the function of the gear is: 丨. transmit power 2 change the power direction 3. change the rotation speed, the gear can not For the transmission of the individual driving power, at least two or more gears must be engaged with each other to achieve the transmission purpose. The number of teeth of the drive gear of the set-segment gear mechanism is M, the rotational speed is ml, and the number of teeth recorded passively is m2. The calculation of the ratio is as follows: The revolution ratio = n2 / nl = ml / m2 According to the value of the revolution ratio, a section of the gear mechanism can be divided into three categories: 1. The revolution ratio is < 1 increasing gear mechanism ml < m2 2. Turn ratio = 1 constant speed gear mechanism mi = m2 3. Revolving ratio > 1 reduction gear mechanism mi > m2 In the automatic industrial towel Ma Lai is very narration, the motor category is structural and control methods Divided into surface motor, AC motor, 彳 马达 motor from Qianma material, where ^ from the point of view of power output, DC motor, AC motor is good _ force output; but if ^ 201241353 control accuracy and financial direction, take care of the motor and Money ride _ is the age of the Xin, stepping Da is - face punch motor 'secret from the record _ mosquito needle, can be switched to the stator to the fourth (four) current, step-by-step _ motor, stepping ride pulse signal control, you can simply Achieve high-level mosquito bites, and make 4 objects stop at high precision at the target position, and the surface structure can be divided into three types: permanent magnet pM < (pe_ent magnet _, yoke VR riablefeluetoe _, and composite T-shirt ^ type) 'Locate in the basic spicy (four) angle unit. Take the 5-phase step as an example. The basic step angle is G. 72, so you can turn the motor! The circle is divided into 5 (10) aliquots (= 36 () degrees / 〇. 72), in this way to subdivide each travel volume as a positioning reference, the static angle error refers to the gap between the theoretical and real stop of the motor , this difference generation is the arbitrary stop position of the (four) sub-starting point 'measured every 1 step' total measurement 36 "angle (+) maximum value and (") wide between the stepping stepping motor In the no-load state, it will remain ±3 points (10)5. The angular accuracy within the 'this-slight angle error U is mainly from the mechanical precision of the rotor and the stator; and the slight anti- _ 柯 柯, but the presence of friction load must be present at the moment Accuracy can be seen from the angle-torque characteristics, which will result in different angular shifts due to different friction loads. First, the moon shape secret is a (10) single-separated design, installed in a fixed-spaced light bulb of the same size. 'When the light bulb is illuminated, the effect of the interval is the shadow effect, which produces a similar shape of the moon, semi-circular moon or moon. However, there are quite a few shortcomings in this design, mainly including the limitation of the phase change of the moon phase, which is quite limited, and it is impossible to accurately represent the moon and the moon, and of course, it is impossible to follow the moon of the money festival.

Please refer to Figure 2A. Gu 2 B ' is a front structure diagram of a luminaire structure with occlusion fruit. The luminaire structure includes: - a lamp holder 110, a lamp cover 12 〇, a driving device 14 〇, a driving gear 161, A driven gear 162---passive gear 163, a light source 150, a fixing portion 17, a fixing portion 172, a fixing portion 173, a rotating shaft (8), a rotating shaft 182, a light shielding plate 191, and a light shielding plate 192' The b-perspective view shows that the components are mounted on the lamp holder 11 , and then covered by the lamp cover 120. The mounting positions of the components are as follows, wherein the driving device (10) can be driven by a ship motor or a stepping motor. The time-infeed motor is controlled by the __ control weaving, and the control circuit is controlled by the writer control program according to the daily moon phase controlling the required rotation angle of the driving device 140, the driving gear 16 the driven gear 162, and the driven gear 163. In combination, 201241353 is a gear assembly. In this embodiment, the illumination source 150 uses an -LED, and the system 150 is fixed to the center of the socket, the fixing portion 171 and the fixing portion 172 are mounted on both sides of Weiyuan at an appropriate distance, and the rotating shaft (8) and the rotating shaft are rotated. The shaft 182 is mounted on the fixing portion 171 and fixed 172 _, the rotating shaft 181 and the rotating shaft 182 are located at an appropriate distance from the position of the light source, and the light shielding plate 191 and the light shielding plate 192 are respectively mounted on the rotating shaft 181 and the rotating shaft 182, and the shape thereof is approximately semi-elliptical, and the rotating shaft 181 and the rotating shaft 182 are the same. The rotating shaft 162 and the driven gear 163 are combined with each other. When the driven gear 162 rotates, the rotating shaft 181 also rotates synchronously. When the driven gear 163 rotates, the rotating shaft 182 also rotates synchronously, and the driving device 140 is fixed in the fixing portion 173. On the lamp holder u, the driving device 14 is mounted with a driving gear 161 on its rotating shaft. When the driving gear 161 rotates, the driven gears 162 and 163' are driven to block the light source 15 by the light shielding plate 191 and the light shielding plate 192. The light that is irradiated is used to achieve the object of the present invention. The illuminating device with the light-shielding effect of the invention has the action mode that when the luminaire is activated to display the moon phase as the full moon, the visor 191 and the visor 192 are flatly attached to the lamp holder 11 ,, and the moon phase is the first chord month. The control device 130 controls the driving device 140 to rotate the driving gear 16 to drive the driven gear 163 according to the set angle rotation and rotation time.
