The contents of the floodlighting technical requirements are very detailed, including the inspection and installation of various systems and components. These will be documented before construction and construction will be carried out only after the construction and customer confirmation. The reason why we want to talk about this technical requirement is because our environment is not suitable for general use. We must formulate corresponding technical indicators based on our environment. For example, the construction of cables and pipelines will involve many problems. For flood lighting technical requirements is a major project, let's take a look at the technical requirements of cable and piping.
Flood Lighting Introduction
a) Flood lighting applications
The application of floodlighting is more acceptable in terms of its use in two aspects. One is for safety and work needs, such as parking lots, stadiums, etc. Under these circumstances, floodlighting is mainly for the sake of safety and work. The second is to present the outline of the building, the city government, the White House, Tiananmen, etc. These are all for presenting the outline of the building and making it more visible in the darkness. The exterior of the wrapping stadium is also the lighting fixtures that are used to present the exterior of the building. There are also floodlighting of some high buildings to provide guidance and keep the aircraft in the dark away from these buildings.
b) Flood Lighting Brand
There are many brands of flood lighting, but the brand reputation is good, the quality of the pass is still a few professional production of lamps for many years to the brand, such as Philips, Op, Philips produces a lot of types of lamps, this type of flood lighting or There are production, there are Friends of Fung, Branch name, the United States Shibo, in fact, there are also some manufacturers specializing in the production of flood lighting lamps, these may not be famous, but the production of the product is still very pass, such as LED, COB, Shopp and so on.
c) The price of flood lighting
The price of flood lighting is not too expensive, after all, the power is not too great, mainly because of the waterproof and durability, so the price is slightly higher than ordinary lighting fixtures. For example, LED explosion-proof lamps used in gas stations and so on are about 800 yuan, because of the explosion-proof function, the price of other floodlights is less than five hundred, are normal prices, if the use of special emphasis on the price will be higher, , but not particularly high, so the prices are the same, are similar.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!
Floodlighting technical requirements
1, incidence angle
It is the shadows that stand out from the facade. Therefore, the illumination should always provide surface imaging. Lights that face the facade at right angles will not be shaded and the surface will appear flat. The size of the shadow depends on the surface relief and the angle of incidence of the light. The average lighting direction angle should be 45°. If the undulation is extremely small, this angle should be greater than 45°.
2, lighting direction
In order for the surface illumination to appear balanced, all shadows should be projected in the same direction, and all luminaires that illuminate the surface in one projection area should have the same projection direction. For example, if two lights are aimed symmetrically at the vertical direction of a surface, the shadows will be reduced and confusion may occur. Therefore, it may not be possible to see the surface fluctuations. However, large protrusions can produce large dense shadows. In order to avoid damaging the integrity of the facade, it is advisable to provide weak illumination at a 90° angle to the main light illumination to weaken the shadows.
3, perspective
In order to see the shadows and the surface relief, the lighting direction should be different from the viewing direction. The angle formed by these two directions should be at least 45°. However, for monuments that can be seen from several places, it is impossible to strictly adhere to this rule, and the main observation point should be selected, and this observation direction should be given priority in lighting design.
How to prevent glare in floodlighting
The main factors that cause glare are: the brightness of the light source; the position of the light source; the contrast with the surrounding lighting environment; the size and quantity of the light source, etc. How to control the uncomfortable glare in the flood lighting design? In some of the city's street shops, it is often seen that signboards and advertising signs are floodlit, but the contrast between the brightness of the selected lamps and the surrounding environment is too large, the angles are not properly installed, and the surfaces of many signs are mirror-finished. Caused by the uncomfortable glare, so that in the signboards, advertising sign lighting design, to take into account the surrounding lighting environment, signs of illumination is generally 100 ~ 500lx, in order to ensure better uniformity, install signboards, billboards above The luminaire spacing should be 2.5 to 3 times the bracket length. If the gap is too wide, a fan-shaped bright area will be produced. If side lighting is used, the shade of the lamp must be taken into account so that the unwanted light is reduced as much as possible. In the floodlighting of buildings, it is basically to irradiate the lamp from the bottom up, which is less likely to cause glare.
Flood lighting fixtures installed on the building
In the decorative lighting of a building, the use of as much light as possible produces a full expression of the architectural arts with little or no discomfort caused by glare. In the flood lighting design of a building, light sources and luminaires are selected according to the materials, smoothness and shape of the building surface. The position of the luminaire is installed as far as possible behind the shop plate or the decoration, so that the luminaire avoids people's sight, but the overall lighting effect must be considered and no shadow can be caused. If you can't avoid the line of sight, try to make the lamp as much as possible without damaging the overall effect of the building.
Floodlighting of buildings matches the surrounding environment
If the tall buildings on both sides of the main road are all of the same type of lighting, it will give people a feeling of dullness or even dullness. How to solve this phenomenon?
First, considering the combination of the materials of the building and the light source of the luminaire, the luminosity of the building floodlight is generally between 15-450 lx, and the size depends on the surrounding lighting conditions and the reflection ability of the building material;
Second, consider the combination of the shape of the building and the color of the light source. Colour illumination can be selected according to the shape of the building, creating a distinct color contrast between the front and sides of the building, adding a festive atmosphere;
Third, building floodlighting combined with neon lighting. It is not enough for flood lighting of buildings. It can also be used with neon lighting. In the lighting design of a building, the group building can be decorated with neon lights. The main building can be floodlighted, and the department can choose according to the shape of the building. Neon lights form a main body lighting effect. Special buildings can be equipped with special lighting effects to complement the architecture and the environment.
Editor's summary: The use of floodlighting is becoming more and more widely used, and more and more buildings are beginning to use these lamps for lighting, the effect is very obvious, and the input cost is not too high, so it is very much loved by people, and the flood lighting is in the factory The anti-halation effect is done, and the power is not so great, so there is no need to worry about the great harm to the human body, but also the environmental protection, so people choose them for lighting, which is not unexpected.
