Plug wiring: The plug outlet is to open the outlet hole from the middle of the plug pieces at both ends of the led linear lamp, which will be very convenient to install. The plug outlet cannot be seamlessly connected, and the aesthetics is slightly inferior to that of the bottom outlet. 2. Side wiring: Choose one of the two sides of the led linear lamp to punch an outlet hole equivalent to the wire diameter. The waterproof pairing wiring is connected to the circuit board from this hole. Its advantage is that it can be seamlessly connected. , The brightening effect has no dark areas, and the installation is very convenient. 3. Bottom wiring: the bottom wiring is drilled from the bottom of the two ends of the led linear lamp aluminum profile with a wiring hole equivalent to the wire diameter. The principle is the same as that of the side, which can make the wiring hidden in the bottom position, which is more beautiful. high. 2. What to do if the led billboard is not bright? 1. Leakage. There is a slight leakage in the installation site. When creating the word, the line does not run smoothly, the connector is poorly connected, the second word starts to have a leakage part, and the wiring cabinet tape is opened and grounded. 2. Because the transformer power supply is too small, use a normal necessary transformer. Please use a different transformer according to the size of the word. We use two power supplies (transformers), for example, one word for the first four, one word for the remaining four, and one power supply for the remaining four. Two wiring can solve this problem. It is best to arrange a bit thicker. 3. The arrangement of the lights is uneven. Maybe there are too many LEDs on the road. This can't be done too much. Please contact the manufacturer of the lamp for how many specific belts each has. There are too many straps in some places, too bright in some places, and too little in some places, and the b
Read MoreThe LED floodlight 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. Floodlights 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 to compare 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 cast shadows and mix them on the model. Due to the large range of floodlights, the illumination effect of floodlights 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 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 floodlights: Under small current, the temperature rise of LED flood light 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
Read MoreLED floodlights are also called spotlights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting. And commercial space lighting, the decorative components are heavier, and the appearance is round or square, because it usually has to be tested Considering the reason of heat dissipation, there are still some differences between its appearance and traditional floodlights. LED flood light classification: 1. Rotationally symmetrical shape The luminaire adopts a rotationally symmetrical reflector, and the symmetry axis of the light source with rotationally symmetrical light distribution is along the reflector axis Line installation. The iso-intensity curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, the illuminated surface Obtain an elliptical spot with uneven illumination; however, when multiple lamps are illuminated, the spots are superimposed on each other, which can produce satisfactory Lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium. Above, get high illuminance, high uniformity lighting effect. 2. Two symmetrical plane shapes The iso-intensity curve of this type of projector has two symmetry planes. Most of the lamps use symmetrical cylindrical reflectors, and The linear light source is installed along the cylindrical axis. 3. A symmetrical plane shape The isobaric intensity curve of the luminaire has only one symmetry plane (Figure 2). The lamps are made of asymmetric cylindrical reflectors Or a symmetrical cylindrical reflector plus a grid that restricts light. The most typical is the sharp cut-off block retracted light distribution. This kind of light A single lamp with strong distribution can obtain a more satisfactory illuminance distribution. 4. Asymmetrical shape The iso-intensity curve of this t
Read MoreLED lighting and control can improve TV broadcasting Due to its particularity, the sports lighting system has special requirements for lighting. In the early days, we used incandescent lamps, and later "metal halide lamps", and then to today's brilliant LED sports lighting, which is played by TV broadcasting. important role! From amateur games to the Premier League, LED enhances television broadcasting by eliminating stroboscopic slow-motion playback (a problem that is common with metal halide lamps). Equipped with an advanced LED sports lighting system, these clips can now be played without flicker at a speed of 20,000 frames per second, so the audience can capture every second of the replay in detail. When LED sports lighting is used to illuminate the playing field, because LED lighting can strike a balance between warm and cool colors, the image appears brighter and clearer on the TV. There are almost no shadows, glare or spilled light, so the movement remains clear and smooth. The LED system can also be adjusted according to the venue of the game, the time of the game, and the type of game broadcast. LED system can enhance fans' experience in the game With the help of the LED sports lighting system, the audience has a better experience, which not only improves the viewing of the game, but also increases the audience's participation. The LED has the function of being turned on and used immediately, and the lights can be adjusted immediately during the half-time break or during the intermission of the game. Imagine if your favorite team throws the buzzer 2 seconds before the end of the field, the timer just goes to 0 seconds, the lights are on and the ball hits, what the reaction of the fans in the stadium will be. The lighting engineer can use a controllable LED system to tailor this moment and boost the morale of the players. In turn, fans will feel that they are part of the game. Advanced lighting system can reduce opera
