LED ROAD LAMP

摘要

A LED road lamp comprises a light distribution system (1), a heat sink (2), a lamp body (3), a driver circuit (4) and a lamp installing and adjusting mechanism (5). Each of the LED light emitting units (11a, 11b, 11c) of the light distribution system (1) irradiates to the points on the region of the road surface respectively, and every incident point corresponds to each of the LED light emitting units (11a, 11b, 11c) of the light distribution system. Based on the distance and incident angle from the LED light emitting unit to the incident point, the optical axis direction, luminous intensity and radiation angle range of each of the LED lightemitting units (11a, 11b, 11c) are determined. According to the incident angle and luminous intensity, LED light emitting units form several lighting modules fixed to the appropriate position of the light distribution system, so that each LED unit has the best optical system desired by the road lighting.
