What are the floodlight exposure range and characteristics?

Floodlights and spotlights are not the same, floodlights can create a relatively high level of diffuse light, this light has no direction, and the outline is very clear. What is the range of the floodlights? There is no specific exposure range of floodlights, because the light of floodlights is relatively weak, is a relatively slow light, will not produce shadows. Floodlight is a relatively boundary-free beam that can illuminate a certain specific area, so let's take a look at the range of floodlight exposure.

 

I. Scope

 

Floodlights are not spotlights, projectors, spotlights. Floodlights produce a highly diffuse, directionless light rather than a well-defined beam, resulting in soft and transparent shadows, and when used for object lighting, the speed of illumination is much slower than when illuminated with spotlights, and even some floodlights that weaken very slowly look like a light source that does not produce shadows. Spotlights, on the other hand, cast a directed, well-defined beam of light that illuminates a specific area.

 

Ii. Materials

 

The lamp body material is aluminum alloy die-casting molding electrostatic spraying surface treatment, coating high temperature resistance, acid and alkali resistance, anti-aging lamp body adopts light source electrical integration design, compact structure, small volume reflector imported high-purity aluminum, a variety of reflective surface design, forming a variety of different needs of light distribution, high light efficiency, glare small light source can follow customer needs, Can use single-ended or double-ended gold halide lamp or high-pressure sodium lamp holder using E40 or RX7s mask 5mm tempered glass, safety, high temperature resistance, high strength, good light transmission seal for anti-corrosion silicone rubber seal, good sealing, waterproof, dustproof application high-performance inductive ballast, trigger and capacitor, To ensure that the electrical performance of the lamp meets the requirements of the national standard, the internal connection is 1mm2PVC, which is suitable for markers, stadiums, squares, trees, billboards, parking lots, building exterior walls, etc.

Iii. Characteristics

 

Floodlight, as a replacement of electric light source, has been recognized by more and more people and has been applied in many fields. Its main features are as follows:

 

1, life advantages: general incandescent lamps, fluorescent lamps, energy-saving lamps, and other gas discharge lamps have a filament or electrode, and the sputtering effect of the filament or electrode is precisely the inevitable component that limits the service life of the lamp. High frequency electrodeless discharge lamps require little or no maintenance and have high reliability. Service life of up to 60,000 hours (10 hours per day, life can reach more than 10 years). Compared with other lamps: 60 times that of incandescent lamps; 12 times more than CFLS; 12 times more than fluorescent lamps; 20 times that of high-pressure mercury lamps; The long life of the floodlight greatly reduces the maintenance troubles and replacement times, saves material costs and labor costs, and ensures long-term normal use. Because the floodlight has no electrode, it emits light by combining the principle of electromagnetic induction with the principle of fluorescent discharge, so it does not exist the necessary components that limit the life. The service life depends only on the quality level of the electronic components, the circuit design and the manufacturing process of the foam body, and the general service life can reach 60,000 to 100,000 hours.

2, energy saving: compared with incandescent lamps, energy saving of about 75%, 85W floodlight flux and 500W incandescent light flux is roughly equivalent.

 

3, environmental protection: It uses solid mercury agent, even if broken will not cause pollution to the environment, there is a recovery rate of more than 99%, is a real environmental green light source.

 

4, no stroboscopic: because of its high working frequency, it is regarded as "no stroboscopic effect at all", which will not cause eye fatigue and protect eye health.

 

5, good color rendering: the color rendering index is greater than 80, the light color is soft, showing the natural color of the illuminated object.

 

6, color temperature optional: from 2700K to 6500K by the customer according to the need to choose, and can be made into color bulbs for garden decoration lighting.

 

7, high proportion of visible light: in the emitted light, the proportion of visible light is more than 80%, and the visual effect is good.

 

8, no need to preheat. It can be started and restarted immediately, and multiple switches will not have the phenomenon of light decay in ordinary discharge lamps with electrodes.

 

9, excellent electrical performance: high power factor, low current harmonics, constant voltage power supply, constant output luminous flux.

10, installation adaptability: can be installed in any direction, without restrictions.

Floodlight is a kind of light that can be used as a substitute for a light source, which is mainly used on the stage. The service life of the reflector is very long, because the floodlight is not the same as the ordinary lamp, the ordinary lamp is the use of filament or electrode floodlight using current.

 

Floodlight is also very environmentally friendly, because the floodlight is a solid mercury agent, which will not damage the environment when used, and has a certain role in protecting the environment, and is a green light source with a high recovery rate. Many places will choose floodlights as the main light source.
