With the progress of society, people pay more and more attention to physical and mental health. Various sports have also become entertainment activities for the whole people. Various sports have enthusiastic fans in all corners of the world. Whether it is a participant or a person watching the game, the requirements for lighting are getting higher and higher. It is required to have uniform brightness, anti-glare, and anti-overflow light to provide athletes and referees with a healthier and more comfortable sports light environment. It is also required to improve the viewing of the game and the participation of the audience. Spectators also require that they must pay close attention to athletes and competitions in a comfortable and pleasant environment. This requires that the LED sports lights have the function of turning on and on, and the lights can be adjusted immediately during halftime or between games. The lighting design of the stadium should not only meet the needs of various personnel on the scene, but also provide high-quality TV broadcast scenes for most TV audiences watching the game. Therefore, good lighting occupies an important position in modern stadiums. So, what kind of light is most suitable for sports fields? This article will find the most true answer for you.
The main factors affecting the lighting effect of the stadium are: light uniformity, color temperature of LED stadium lights, and excellent color rendering index.
The more uniform the light distribution, the better the illuminance and the more comfortable the visual experience. The closer the illuminance uniformity is to 1, the better; on the contrary, the smaller it is, the more visual fatigue. Illuminance uniformity = minimum illuminance value/average illuminance value, the minimum illuminance value is calculated according to the point-by-point calculation method. Formula: U0=Emin/Eav, U1=Emin/Emax, U2=1-((Emax-min)/Eav)
Color temperature is a unit of measurement that indicates the color components contained in light. Color temperature is a unit of measurement that indicates the color components contained in light. Theoretically speaking, the black body temperature refers to the color of the absolute black body after being heated from absolute zero (-273°C). After the black body is heated, it gradually turns from black to red, turns yellow, turns white, and finally emits blue light. When heated to a certain temperature, the spectral component of the light emitted by the black body is called the color temperature at this temperature, and the unit of measurement is "K" (Kelvin). The warm white range is generally 3000-3200K, the normal white range is generally 6000-6500K, the natural white range is generally 3500K~4500K, and the cool white range is above 8000K. Sports lighting (such as table tennis court lighting, billiard lighting) requires natural white lighting. The color temperature is about 4000K, and the color temperature of football and basketball courts is between 5000K and 5700K. The color temperature of hishine stadium lights can meet all sports lighting needs.
In order to achieve a good color TV broadcast effect, the lighting quality of the stadium is not only related to the illuminance, but also closely related to the color temperature and color rendering of the lighting source. Article 3.3.2 of my country's "Civil Building Lighting Design Standard" GBJ133-90 stipulates that the color rendering index Ra of general light sources for color TV broadcasting should not be less than 65. According to the requirements of CIE NO.83 and FIFA, the light source The correlated color temperature Tc is greater than 5000K and the light source color rendering index Ra is greater than or equal to 80 to achieve the best on-site lighting effects and color TV broadcast effects.(as shown in the above picture for clear contrast display)
We choose the best LED stadium lights, we must choose the excellent quality lights, such as good heat dissipation structure, convenient heat dissipation, independent power control system and embedded button control box, easy to repair and replace, lens angle selection Many, long shelf life, high typhoon resistance, high IP index. As we all know, the high-power sports light chip generates more heat. Therefore, a good heat dissipation structure is extremely important for sports lights. It can not only greatly increase the service life of lamps and reduce light decay, but also ensure the safe use of lamps. Hishine conducted repeated experiments on sports lights for 10 years, and finally used a unique hexagonal heat dissipation structure, which can quickly dissipate heat. Hishine can ensure the same luminous efficiency within 7 years, and the life span exceeds 50,000 hours.
Lumen, a unit of luminous flux. A point light source with a luminous intensity of 1 candela (cd) has a luminous flux per unit solid angle (1 steradian) of "1 lumen", the English abbreviation (lm). The so-called lumen simply refers to the brightness of a candle light one meter away (1 meter = 1 meter). Lumen is a unit of luminous flux. In principle, the greater the luminous flux, the better, but the increase in luminous flux is achieved by increasing the current. This may bring about two negative effects: a. High current can easily cause light decay. b. When the luminous flux is high, the color rendering will decrease. Hishine uses high-quality Lumileds lamp beads, which reduces these two negative effects to zero.
Because the stadium area is large and usually open in the open, it is inevitable that there will be typhoons and heavy rains, so the sports lights need a wind resistance level of 10 or more. High-pressure jet water has no effect and completely prevents dust from entering. Therefore, the IP index cannot be less than IP65.
For the installation of sports lights, the simpler the more convenient. The simpler the lamp technology, the more mature. And the guide has a variety of installation methods, so as to be suitable for various occasions. The usual installation methods include 360° rotating bracket, round rod bracket, U-shaped bracket and other installation methods.
The color rendering index (CRI) refers to the ability of the light source to restore the visual perception of the object under the sun. The higher the color rendering, the closer the color rendering index value is to 100, the stronger the ability to restore the color of the object, and the easier it is for the human eye to distinguish the color of the object.
sports lighting needs natural white lighting, the color temperature is about 4000K, and the color temperature of football and basketball courts is between 5000K and 5700K.
With the following knowledge, you know what kinds of led light you should take. But are there any special outdoor lamps worth recommending? Of course, we have some private mold led light used for outdoor. Here is a summary of some noteworthy products for your reference.
