As the earth's resources become increasingly scarce, the investment cost of basic energy is increasing, and various safety and pollution hazards can be said to be ubiquitous. As a kind of "inexhaustible and inexhaustible" safe and environmentally friendly new energy source, solar powered has attracted more and more attention. In this way, solar powered garden lights products should emerge with the popularization of solar water heaters. Here we make a practical comparison between the effects of solar garden lights and the use of city electricity lamps.Advantages of solar garden lights:The solar garden light is easy to install: When installing, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws. ComparedSolar lighting lamps are free of electricity fees: Solar courtyard lamps are a one-time investment, without any maintenance costs, the investment cost can be recovered in three years, and long-term benefits. There is no hidden safety hazard for solar lamps: solar lamps are ultra-low voltage products, which are safe and reliable in operation.isadvantages of solar garden lights:Low efficiency and high cost: Some aspects of the development level of solar energy utilization are theoretically feasible and technically mature. However, some solar energy utilization devices have low efficiency and high cost. In general, the economy cannot compete with conventional energy sources.Dispersibility: Although the total amount of solar radiation reaching the earth's surface is large, the energy flow density is very low. Therefore, when using solar energy, to obtain a certain conversion power, a set of collection and conversion equipment with a considerable area is often required, and the cost is relatively high.Instability: The solar irradiance that reaches a certain ground is both intermittent and extremely unstable. In order to make solar energy a continuous and stable energy source, it will eventually become an alternative energy source that can compete with conventional energy sources. It is necessary to solve the problem of energy storage, that is, to store the solar radiant energy during the sunny day as much as possible for use at night or on cloudy and rainy days. However, energy storage is also one of the weaker links in the utilization of solar energy.
Many buyers always step on the "thunder" when buying led garden lights, either they are not suitable, or the effect of courtyard lights is not good. In order to help you solve these problems, today I will tell you what to pay attention to in the procurement process.Pay attention to the type of lampsThere are various types of led garden lights. According to the style, they can be divided into European style, Chinese style, and classical style. According to the light source, they can also be divided into solar courtyard lights and LED courtyard lights. Different types will have different effects. Of course, the shape and size of courtyard lights are also very different. Consumers can choose according to their own preferences and courtyard decoration style.Pay attention to the lighting effectWhen choosing a garden lamp, you should also pay attention to the lighting effect. First of all, the area of the lamp should be wide, so that it is more convenient for people to walk at night. Secondly, the brightness of the light should be appropriate, not too dazzling, otherwise it will make people feel dizzy. It is recommended to choose a light source with warm colors to help create a courtyard atmosphere.Consider the special venueWhen choosing a led garden lights, you should also consider the actual situation. The courtyard of different families will have different environments, some are relatively humid and dark, some are relatively dry and hot, and the lamps suitable for different environments are also different, so it should be based on the environmental conditions. Choose the corresponding lamps. In order to prevent accidents such as electric shock and burns, protective measures must be taken.Pay attention to the shell materialThere are different materials for the outer shell of garden lights. The most common ones are aluminum, iron and steel. Different materials have different characteristics and different decoration effects. The steel material has a strong texture and is durable, while aluminum and iron have a good decorative effect in addition to lighting. Consumers can choose according to their own ideas and courtyard decoration.Consider economyPrice is a factor that people are more concerned about. In addition to paying attention to the quality and appearance of led garden lights, they must also consider whether they are economical. Try to avoid choosing low-priced lamps, because they may be of poor quality, resulting in frequent leakage or abnormal use, which will increase operating costs. On the contrary, high-priced lamps have guaranteed quality, are durable, and have less operating costs, saving money and effort.Pay attention to decorationThe courtyard is also a part of the family, so the garden lights must also have a certain decorative nature, which can make the environment more elegant and beautiful, pleasing to the eye, and also highlight the life style and style of the head of the household.
The LED flood lighting is a point light source that can illuminate uniformly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Floodlights are the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results.Flood lighting are the most widely used light source in renderings. Multiple floodlights can be used in the scene to coordinate their effects to produce better results. It is to illuminate the object uniformly in all directions from a specific point. It is best to use it as an analogy to a light bulb and a candle. Floodlights can be placed anywhere in the scene.For example, it can be placed outside the camera's range or inside an object. It is common to use many different colored floodlights in the scene at a distance. These floodlights can project and blend the darkness on the model. Because the floodlight has a relatively large illumination range, the illumination effect of the floodlight is very easy to predict, and there are many auxiliary uses of this kind of light. For example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. It produces a bright light.It should be noted that the floodlights cannot be built too much, otherwise the renderings will appear flat and dull. Therefore, in the usual rendering of renderings, pay more attention to the impact of lighting parameters and layout on the light perception of the entire renderings scene, accumulate more experience, and master the lighting matching skills.Features of flood lighting:Under small current, the temperature rise of LED flood lighting is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the luminescence will deteriorate. In particular, the temperature rise of dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So the heat dissipation design is very important.
Stadium sport lighting sources can be incandescent lamps, fluorescent lamps, metal halide lamps, high-pressure sodium lamps and other types of lamps. These light sources have certain advantages, but they also have certain limitations. For example, stadium lighting requires high color rendering and color temperature to meet the needs of TV broadcasting. At the same time, the light source should ensure the most sufficient light intensity under the premise of the most energy-saving, in line with the principle of economical design. After years of research and practice, metal halide lamps are widely used as the light source of sports lighting in the world. Small gymnasiums have lower ceilings and more use of incandescent lamps.In addition to the type of luminaire, the gymnasium should also choose according to the lighting efficiency of the luminaire. Commonly used are deep-illuminated, oblique-illuminated or flood-illuminated luminaires. These types can not only ensure the illumination of the horizontal plane, but also ensure the verticality. The illuminance of the surface.Due to the large space of indoor gymnasiums, most of the light sources adopt the method of adding reflectors to improve the efficiency and intensity of light. However, due to the fierce sports such as balls, most of the light sources need to be equipped with protective nets. Moreover, the location of the ceiling is relatively high, and the lamps and lanterns have certain difficulties in installation, maintenance and maintenance.The lighting control system of a comprehensive gymnasium sport lighting should have the following characteristics:1) The light source has good color temperature and color rendering, and sufficient illumination, which can meet the daily training and competition needs of athletes;2) Improve the lighting layout plan and simplify the operation steps, thereby reducing operating costs; 3) In addition to the basic lighting needs, in order to cooperate with various commercial activities, the lighting should be fashionable.
