Ming feng lighting has been producing the LED light for more than 10 years, usually speaking,The lamp is usually installed on the lamp post with a height of less than 15m, and is regularly and continuously set on one side, two sides or the middle of the road according to a certain distance for lighting. When this lighting mode is adopted, the longitudinal axis of the lamp is perpendicular to the road axis, so that most of the light emitted by the lamp is directed to the longitudinal axis of the road. MF talent engineer would like to share this knowleadge as following,
2.0.8 high mast lighting
A group of lamps and lanterns are installed on the lamp pole with height equal to or greater than 20m for large area lighting.
2.0.9 semi height lighting
A group of lamps and lanterns are installed on the lamp pole with a height of 15-20m for lighting. When the lamps are configured according to the conventional lighting mode, it belongs to the conventional lighting; When the lamps are configured according to the high pole lighting mode, it belongs to high pole lighting.
2.0.10 cut off luminaire
The angle between the maximum light intensity direction and the vertical axis of the lamp is 0 °~ sixty-five ° Between, 90 ° Angle and 80 ° The maximum allowable values of light intensity in the angular direction are 10CD / 1000lm and 30CD / 1000lm respectively. And regardless of the luminous flux of the light source, it is within 90 ° The maximum light intensity in the angular direction shall not exceed 1000 CD.
2.0.11 semi cut off luminaire
The angle between the maximum light intensity direction and the vertical axis of the lamp is 0 °~ seventy-five ° Between, 90 ° Angle and 80 ° The maximum allowable values of light intensity in the angular direction are 50CD / 1000lm and 100cd / 1000lm respectively. And regardless of the luminous flux of the light source, it is within 90 ° The maximum light intensity in the angular direction shall not exceed 1000 CD.
2.0.12 non cut off luminaire
The maximum light intensity direction of the lamp is not limited, 90 ° The maximum value of light intensity in the angular direction shall not exceed 1000cd.
2.0.13 floodlight
The beam diffusion angle (the angle between two directions where the light intensity is 1 / 10 of the peak light intensity) is greater than 10 °、 A projector for floodlighting. Usually it can rotate and point in any direction.
Lamp parameter correlation
2.0.14 luminaire efficiency
Under the same use conditions, the ratio of the total luminous flux emitted by the lamp to the total luminous flux emitted by all light sources in the lamp.
2.0.15 maintenance factor
The ratio of the average illuminance or average brightness on the specified surface after a certain period of use of a lighting device to the average illuminance or average brightness on the same surface when the device is newly installed under the same conditions.
