Description
Technical field
The invention discloses a kind of structure of LED modular street lamp holder with adjustable irradiating angle, belong to technical field of semiconductor illumination.
Background technology
Light source that street lighting adopts has at present: incandescent lamp, high-pressure sodium lamp, high-pressure mercury lamp, metal halide lamp, fluorescent lamp etc., and the major defect that these lamps exist is: 1. not environmental protection: it is harmful to environment to contain heavy metal substances such as mercury, lead, arsenic; 2. high energy consumption; 3. short life.
Contain heavy metal substance in the conventional road lamp light source, contaminated environment; Led light source does not contain heavy metal substance, does not pollute the environment.Because the conventional road lamp light source is globe-type luminescence, light is dispersed and is difficult for control, and light easily overflows the appointment irradiation area, so form light pollution; LED is because lighting angle can be set, and light is controlled, can allow light full illumination appointed area, so there is not light pollution.
The energy consumption of conventional road lamp light source be LED 5-10 doubly, particularly under the very nervous background of China's current power energy, select led light source can fundamentally solve the high energy consumption and the great number electricity charge problem of conventional road lamp as road-light light-source.
Aspect colour rendering: conventional road lamp is relatively poor, and as sodium vapor lamp, colour rendering index can only reach about 30; And the LED colour rendering index can reach more than 75, and more near the natural lighting effect, from human vision susceptibility angle: the LED street lamp is more suitable for road lighting.
Aspect the uniformity: the conventional road lamp uniformity is low, though vertical illumination can reach road illumination standards, edge illumination is well below vertical illumination, and the uniformity is poor, can not reach road illumination standards; LED can control owing to light emission direction, uniformity height, and vertical illumination and edge illumination all reach road illumination standards.
Conventional road lamp can only reach the level of " bright ", the level of illumination " matter " that is far from being.Because the light source of conventional road lamp is globe-type luminescence, direction of light is uncontrollable, forms the circular iris hot spot on the road surface, produces local shade, and illuminating effect is not good, pedestrian and vehicle drive personnel is impacted in visual aspects, so be easy to generate traffic accident.And the LED street lamp is except improving illuminating effect aspect the colour rendering and the uniformity, also because the LED light emission direction has controllability lighting angle lockable, design by secondary light-distribution, on illuminating road, form a complete light belt, there is not shade, can not impact in visual aspects, have good road lighting effect, improve road safety greatly pedestrian and vehicle drive personnel.
Present LED street lamp both domestic and external is various in style, and spread in performance is uneven.Existing LED street lamp mainly is made of lamp holder loam cake, lamp holder lower cover, led light source driver, led light source modular assembly, lamp holder end cap, lamp bracket etc., because the LED light fixture in quality and the restriction of dispelling the heat aspect requiring, is difficult to satisfy the lighting demand of ultra-high power LED street lamp.
