Abstract

A lamp structure having a moon phase change effect comprises a lamp holder (110) for mounting various assemblies, a control circuit (130), a drive device (140), a gear assembly, a rotary shaft set, a light source (150), and a light blocking plate set. The control circuit (130), the drive device (140), the gear assembly, and the light source (150) are mounted in appropriate positions of the lamp holder (110). The control circuit (130) controls the drive device (140) to rotate by an angle according to a set manner. The drive device (140) is connected to the gear assembly, and drives a gear (161, 162, 163) in the gear assembly. The gear assembly is connected to the rotary shaft set. A light blocking plate (191, 192) is mounted on a rotary shaft (181, 182) respectively. The light blocking plate (191, 192) rotates with the rotary shaft (181, 182) in a synchronized manner. When rotating according to the set manner, the drive device (140) drives the gear assembly and the light blocking plate (191, 192). The light blocking plate (191, 192) blocks light from the light source. A blocking effect changes the illumination range of the lamp, so the emitted light produces a set shape, and a moon phase change effect is achieved. Another lamp structure having a moon phase change effect comprises a lamp having a moon phase change effect and a dial set (200) combined with the lamp having a moon phase change effect. When the lamp having a moon phase change effect is placed in regions of different latitude and longitude, the dial set (200) is rotated to make the moon phase presented by the lamp comply with the moon phase deflection angle viewed in the regions of different latitude and longitude.

Description

A luminaire refers to an appliance that transmits light and changes 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 are required. The lighting fixture is an indispensable tool in general life. The improvement of the living function, the good lighting design is to display the function and purpose of the lighting facilities in the most appropriate way, and create an atmosphere of lighting environment. Now the types of lamps are very diverse, such as: home lighting, industrial lighting, Commercial lighting, road lighting, landscape lighting and special lighting, etc., the first use of incandescent light bulbs, with the development of technology to fluorescent lamps, energy-saving lamps, halogen lamps, tungsten halogen lamps and LED special lighting.

Illumination refers to the use of various light sources (such as light bulbs, tubes or light-emitting diodes) to illuminate a particular space, object or environment. Modern artificial lighting mainly uses electric lighting, while gas lamps used in the past ( Gas lamps, candles, oil lamps, etc., the lamps are mainly used for the lighting of the general life when the sun goes down at night. The main indoor lighting can be divided into ceiling lamps and chandeliers hanging on the ceiling. Table lamps and reading lamps, but with the development of science and technology, the function of lamps is not only lighting, but also develops other different functions such as entertainment lanterns, window display decoration] 3⁄4 wall lamp, traffic light for warning indication, can be held Used flashlights, etc.

In recent years, due to the energy crisis and the rising awareness of environmental protection, the pursuit of high efficiency and high color rendering is the direction of the development of light sources. The development of new light sources, various energy-saving energy-saving bulbs and light-emitting diodes have become the focus of technological development. Light-emitting diodes (Light- Emitting Diode) , referred to as LED), when adding forward voltage, the LED can emit monochromatic, discontinuous light, which is a kind of electroluminescence effect, with high efficiency of converting electrical energy into light energy, in proper heat dissipation and application The environment can reach 35,000~50,000 hours of use time, and it is not easy to break. The traditional light source can't compare with the advantages. When changing the chemical composition of the semiconductor material used, the LED can emit light in the near ultraviolet, visible or infrared light. As an alternative to incandescent and fluorescent lamps, known as solid-state lighting (SSL), the efficiency of LEDs has increased rapidly in recent years: At present, the average light output of high-power white light is 60~80 lumens per watt (im/W), the length of LED Life expectancy makes solid-state lighting very attractive. The change of the moon phase in astronomy is because the moon seen by the plexus 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 phase of the moon. That is, when the moon appears in different positions on the orbit, the moon looks like the moon. The moon itself does not emit light because it reflects the sunlight, and only the moon is directly illuminated by the sunlight to reflect the light. The moon seen from the angle will show different reflections. The moon phase is not caused by the earth covering the sun (this is the lunar eclipse), but because we can only see that the moon is illuminated by the sun. The part of the shadow is caused by the shadow of the moon's own dark side. The full moon is when the earth is between the moon and the sun. You can see that the moon is totally reflected by the sun. The new moon is when the moon is between the earth and the sun. We can only see the part of the moon that is not illuminated by the sun. When the local monthly connection of the chord month and the sun and the moon are at right angles, we can see half of the part of the moon that is directly exposed to the sun. Because the lunar calendar is set according to the cycle of the moon, the moon is around the earth. Month, so different lunar dates, the corresponding moon phase is also different, the phase of the moon changes in the order of the new moon (first day) can not see the moon, eyebrows

(Lunar No. 3 ~ No. 5) 1~49% of the right side of the moon is visible, and the first quarter of the moon (Lunar No. 7~8) The 50% of the right side of the moon is visible, and the convex moon is on the right side of the lunar calendar 10th to 12th. 51~99% visible, full moon (Lunar 14th ~ 17th y visible whole moon, then become a concave convex month (Lunar 18th ~ 20th) 5i~99% visible on the left side of the moon, the next string month (Lunar 22 ~ 23 No.) 50% of the left side of the moon is visible, and the moon (No. 29~30) is visible from 1 to 49% of the left side of the moon. The shape of the moon phase seen on different latitudes and longitudes of the Earth on the same day, that is, the profit and loss situation is the same. However, the angle of deflection will be different.

Longitude and latitude is a combination of longitude and latitude. It is also called a geographic coordinate system. It is a spherical coordinate system that defines the space on the earth and can indicate any one on the earth. Position, longitude is divided into 360 degrees, 1 time zone every 15 degrees, of which 0 degree is called the prime meridian, is the first place to enter a new day, and then every 1 time zone to the west is 1 hour, latitude refers to The line angle between a point and the Earth's center and the Earth's equatorial plane is between 0 and 90 degrees, and the equator's latitude is 0°. The planet is divided into the southern hemisphere and the northern hemisphere. The latitude of the point north of the equator is called the north latitude, which is denoted as N. The latitude of the point south of the equator is called the south latitude, which is denoted as S, and the area where the latitude value is between 0 and 30 degrees is called the low latitude area, and the latitude value The area between 30 and 60 degrees is called the mid-latitude area, the area with the latitude value between 60 and 90 degrees is called the high latitude area, and the equator, the Tropic of Cancer, the Tropic of Cancer, the Antarctic Circle and the Arctic Circle are special wefts. Although the prior art has a moon-shaped luminaire, the principle is: using a simple separation design, using a bulb installed in a fixed interval of the size of the singularity, when the bulb is illuminated, a similar chord is generated by the shielding effect of the interval. , semi-circular moon or full moon effect, and this design has quite a few shortcomings, mainly including the limitation of the phase change of the moon phase is quite limited, can not accurately show the moon's cloudy and clear, and certainly can not follow The change of the moon in the Lunar New Year, so the prior art lacks a luminaire structure with a moon phase change effect, which can overcome the above shortcomings and completely exhibit the moon phase change.

In the automation industry, the use of motors is very extensive. The types of motors can be divided into DC motors, AC motors, servo motors and break-in motors by structural and control methods.

The slight angular error is mainly due to the mechanical precision of the rotor and stator and the slight resistance of the stator coil. The value is different, but the practical application must have the existence of friction load. At this time, the angular accuracy can be seen from the angle-torque characteristic, and different angular displacement will occur due to different friction loads.
