The general lighting design is to calculate the illumination of the space in the night state assuming that the window has no light entering, thereby determining the configuration of the lighting device. A good lighting environment must not only have a sufficient source of illumination, but also distribute uniform illumination and avoid glare as much as possible.
Figure 1: The glare effect of the light source
Glare is a visual phenomenon that is caused by an unsuitable brightness distribution or a range of brightness, or an extreme brightness contrast, which causes an uncomfortable feeling or reduces the ability to observe details or targets. At present, there is a serious glare of LEDs on the market. If the human eye is exposed to glare for a long time, it will feel like eyes, dizziness and discomfort. Working under such conditions can cause boredom, irritability and fatigue, which have a great impact on people's production and life. No glare lamps were invented to solve the above problems.
There are usually two types of luminaire glare: direct glare and reflected glare. The glare of LED lights usually refers to reflected glare. As an LED luminaire manufacturer, if you choose a bumpy polycrystalline reflective optical lens, it is completely achievable to combine the optimized optical application design of the frosted tempered glass.
Figure 2: Principle of light output from conventional lenses and reflectors
The above is the light output principle of the lens and reflector commonly used in LED lamps on the market. It is not difficult to imagine that when the light converges in the range of the focus of the eye, the convergence of the light causes the human eye to increase the light intensity when receiving the light, resulting in glare reaction of the eye discomfort; there is also a case where the convergence point of the light is much smaller than the visual focus. The coke is that the light is too weak, resulting in a very weak light intensity, which also makes the human eye uncomfortable due to fatigue, and is one of the factors that cause glare reaction.
The core of solving the above glare problem is how to make the light output evenly in the process of output. Shenzhen Yineng Optoelectronics Technology Co., Ltd. independently invented (patent number ZL201220157321.9) polycrystalline pure parabolic micro-ribbed glare-free technology, using parabolic surface The principle of reflecting uniform parallel light has developed a pure parabolic reflector. The quality of the lighting is different, achieving true glare-free lighting, no light pollution, and high uniformity.
Figure 3: Polycrystalline pure parabolic micro-ribbed glare-free technology
Polycrystalline pure parabolic micro-ribbed glare-free technology, using LED light and physical reflection, make LED lamps without glare, no ghosting, avoiding the brightness of the light source is too glaring, causing disgusting, uncomfortable and other visual discomfort. Applicable to high-end offices, conference rooms, conference halls, reception areas, etc. where lighting visual comfort is high.
Permanent magnet Dc Motor is composed of stator magnetic pole, rotor, brush, case and so on. Stator magnetic pole is made of permanent magnet (permanent magnet steel), ferrite, alnico, ndfeb and other materials, and the rotor is generally made of silicon steel laminated. Enameled wire is wound between two slots in the rotor core (three slots are provided with three windings), and its joints are separately welded on the metal sheet of the commutator. Electric brush is a conductive part connecting power supply and rotor winding. Permanent magnet motor brush USES single metal sheet or metallic graphite brush, electrochemical graphite brush.Permanent Magnet Gear Motor is established using permanent magnet magnetic field of a dc motor. Permanent magnet Gear Motor is widely used in various kinds of portable electronic equipment or apparatus
precision instruments and meters,automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows,etc., wide application range,,Permanent Magnet Gear Motor is usually used in small power occasion.
Features: permanent
magnet gear motor is a kind of rectangular pulse wave, sine wave current, in the form of hybrid permanent magnet motor. Simple structure, high reliability and high efficiency.
Method of use: the best stable in horizontal plane, installed on the permanent magnet gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the permanent magnet gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
permanent magnet gear motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
permanent magnet gear motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of permanent magnet gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
