How to choose LED tunnel lights
Tunnel lighting is an indispensable part of tunnel construction. With the development of LED lighting technology, LED tunnel lights are the current tunnel lighting. The vast majority of new tunnel projects use LED tunnel lights, and the transformation of old tunnel lights is basically also used. LED tunnel light.
1. Light effect:
The level of light efficiency determines the level of operating energy costs, so this parameter is critical. At present, most manufacturers of LED tunnel lights have reached 100lm/W, which can meet the requirements of tunnel lighting efficiency. However, in order to effectively save electricity costs, it is recommended to give priority to choose LED lamps with higher light efficiency. The LED tunnel lights of Shenzhen Zhixiaguang in Shenzhen have a luminous efficiency of up to 150lm/W, which can save electricity costs more than ordinary manufacturers.
2. Drive power:
The service life of LED lamp beads can reach more than 100,000 hours, and the life of the driving power supply is far from the LED light source, so the actual life of the LED tunnel lamp is not determined by the LED light source, but the driving power supply. In order to ensure the service life of LED tunnel lights, it is very important to choose high-quality driving power. Well-known power supply brands in the market include Taiwan Mingwei, Shenzhen Maoshuo, Hangzhou Infinite, etc.
3. Protection grade and surface technology:
The tunnel light is used in outdoor environment. The tunnel has water seepage or dripping. The working environment is relatively bad. The eastern coastal cities have high salt fog in the air, so the lamp should have a high IP protection level, the IP level should not be lower than IP65, and the surface It should be treated by special process, which can prevent salt spray and strong corrosion resistance.
4. Heat dissipation of lamps:
The heat dissipation effect of the lamp directly affects the light decay of the LED light source. Under the same conditions, the luminous decay of the lamp with good heat dissipation performance is less than that of the lamp with poor heat dissipation performance. Therefore, when choosing LED tunnel lights, aluminum lamp body should be used as much as possible, and the heat dissipation structure of the lamp is reasonable and the heat dissipation surface is large. The world known light LED tunnel lamp is a surface light source. The number of LED chips is much more than the conventional LED tunnel lamp of the same power. The corresponding single LED has low current, low temperature, low light source light attenuation, and the lamp life is longer than the general LED tunnel lamp.
5. Glare protection:
From the perspective of driving, the glare problem of the lights has a great impact on the vision of the driver. Glare is an important cause of safety accidents. Therefore, when buying LED tunnel lights, you should pay attention to the anti-glare effect of the tunnel lights. The world-knowledge LED tunnel lamp uses its own core film planar fluorescent LED light source (FLED), which emits light on the plane, the light color is uniform and soft, not dazzling, and the anti-glare effect is good.
6. Color rendering index:
Under the same light effect, the higher the color rendering index, the clearer and brighter it can meet the lighting requirements. For example, the traditional tunnel sodium lamp, although the luminous flux is not low, but because the color rendering index is low, the light looks dimmer. Compared with traditional sodium lamps, LED color rendering index is much higher than traditional sodium lamps. Generally speaking, the color rendering index should be greater than 70. After all, the tunnel is not a fine working place, so the requirements for displaying the indicator are not too high.
7. Color temperature:
The color temperature should be selected according to the specific conditions of the tunnel. For example, in the mountainous areas with heavy fog, it is necessary to use low color temperature, such as warm white light of 3000K color temperature, because the penetration of warm white light at low color temperature is better than that of high color temperature; tunnels without fog, Including urban underground passages, you can choose the color temperature of 5500K-6500K, because the luminous flux of this color temperature section is good, the brightness is good; in general, you can choose 4000-4500K color temperature, natural white light, both.
8. Power factor
Considering the impact on the load of the national grid, high-power lamps such as LED tunnel lights generally require PF>0.9.
