Child nature fun, naughty, with a strong curiosity. If your home socket is not suitable for the installation of the child there is a potential security risk! Led Socket (2) 1. Use of safety sockets Residential building socket installation height is generally 30 cm from the ground, ordinary socket there are security risks, you can use foreign objects into the socket jack. If a child holds a metal object such as a nail into the socket hole, an electric shock may occur. 2. The socket installed in the child out of reach Children's house socket installation height generally 1.8 meters high from the ground, so the child is not easy enough to avoid or reduce the risk of children due to the electric shock. The socket is installed a little higher, the child is far from danger. 3. Manage the wiring board Many parents in order to facilitate the frequent use of wiring board, because most of the wiring board does not have the characteristics of safety sockets, and place...

LED light generated when the heat can not be derived, will make the LED junction temperature is too high, affecting the product life cycle, luminous efficiency, stability. LED heat dissipation: According to different packaging technology, cooling methods are different, and a variety of LED cooling method can be the next schematic: Cooling Path Description: (1) Heat from the air (2). Heat is exported directly from Systemcircuitboard (3). Derived heat from the gold wire (4). If eutectic and Flipchip process, thermal energy will be through the through-hole to the system circuit board and export LED die (Die) to gold, eutectic or flip chip connected to its substrate (SubstrateofLEDDie) to form a LED chip (chip), and then the LED chip fixed to the system board (Systemcircuitboard). Therefore, the possible cooling path of the LED is to heat directly from the air, or through the LED crystal substrate to the system circuit...

1. To improve the level of space lighting Elderly and normal people for the brightness of the light there is a big difference, such as the general lighting, the elderly brightness of the standard value is 1.5 times the normal person, and traffic lighting and late night lighting gap is greater, 3-5 times The This requires the need to improve the level of illumination, you can use some bright colors of diffuse materials do walls, ceilings and floors, to ensure the brightness of the room. 2. The appropriate increase in visual contrast Appropriate use of key lighting to improve the safety factor, with lighting to create the brightness contrast space constraints, so that the level of clear location clear, while the use of color contrast to the space to convey the visual information easy to identify. Led downlight (2) 3. The visual level is more clear Avoid the use of complex decoration, complex gorgeous light environment is not conducive to the elderly...
Wind and solar energy is complementary to the natural energy of wind and solar energy through the wind motor and solar panels to convert the power to recharge the battery. When the wind to go to more than three times, it will be through the wind to power lighting, and lack of wind when the solar panels will be charged through the electricity to carry out lighting. Lighting time and control: wind and solar energy is complementary to the configuration of the 400LW wind turbine, a 100W solar panels, a set of 60WLED lamps and 200AH / 12V lead-acid valve control battery two, Composed of wind and solar street lighting system, can ensure reliable daily light 8 to 10 hours. solar street lights (2) Reliability: in the last three to five days without wind energy, solar charging under the circumstances, the scenery is still complementary to the solar street lighting is still able to work properly, light control lights, time control lights; hal...
Do you have found whether it is LED bulb, LED ceiling light, LED lamp, LED flood light, LED mining lamp, etc., they are easier to break in summer, much worse than the probability of winter, why? Led can light (2) The answer to one: the lamp cooling is not good, the summer weather temperature is relatively high, LED light will be fever, the lamp is to burn out. So what is the reason for that? 1. Lamps thermal conductivity material is not enough, such as the existing low-quality bulb plastic, there is no heat radiator, light heat can not lead, how not bad? 2. Lighting design is unreasonable, a lot of lighting is not a thermal design, said directly to the assembly of accessories, not through scientific experiments, how not bad? 3. Installation environment is irrational, LED lighting installation requires a certain amount of cooling space to heat, there is the installation environment is wet, LED lamps in the wet environment,...
LED filament is also called LED lamp post. In the past LED light source to achieve a certain degree of light intensity and light area,that need to install the lens and the like optical devices and will affecting the lighting effect, reduce the energy saving. LED filament is 360 ° full angle Luminous, large angle light and without lens, achieving three-dimensional light source, bringing unprecedented lighting experience. 1,360 ° light angle. 2, integrated high-voltage drive, the power factor to maximize power, lighting costs to minimize. 3, high-quality light source, color rendering index of 90 or more, light efficiency 110lm / W or more. 4, with a transparent substrate material with a new 360 ° molding packaging process. 5, fluorescent glue molding process, good quality. 6, the new light vision, feel the original ecology of the "incandescent" light environment. LED filament can be used in crystal chandeliers, candle lights, bulb lights, w...

First, the voltage and current 1. Do not recommend the use of LED in parallel, because even the same model, the same batch of LED operating voltage has a certain difference, unless the current circuit. 2. In the installation of ultra-bright white LED, there must be anti-static facilities, because the electrostatic damage to the ultra-bright white LED even if the naked eye can not see, will reduce the service life. 3. If the LED operating voltage changes 0.1V, then the working current may change about 20mA. Under normal circumstances the use of series current limiting resistor, you can also use a simple constant voltage circuit, the purpose is to do automatic pressure limiting current limiting, to prevent damage to the LED. 4. The peak current of ordinary LED is 50 ~ 100mA, the reverse voltage is about 6V. When applying LED, pay attention to the design of the circuit when the peak voltage and current do not exceed this limit. (Ex...
