Abstract

The invention discloses an LED white-light illuminating street lamp comprising at least one bearing base board, a plurality of red-light LED packaging elements, green-light LED packaging elements and blue-light LED packaging elements, wherein all LED packaging elements are arranged on the bearing base board; the bearing base board is arranged on a lamp holder, and the lamp holder can be arranged on a lamp post; and light beams emitted by the LED packaging element with various light colors can be uniformly mixed into white light so that the breadth and the brightness of illumination are enhanced. In addition, the color temperature of the white light can be easily adjusted by adjusting the quantity and the setting positions of the LED packaging elements with various light colors; and moreover, the LED white-light illuminating street lamp also has high color rendering performance.

Description

technical field [0001] The invention relates to a lighting street lamp, in particular to an LED white light lighting street lamp with uniform light mixing, easy adjustment of color temperature and high color rendering. Background technique [0002] Since Light Emitting Diode (LED) has the characteristics and advantages of low energy consumption and high efficiency, all countries and industries have listed this technology as a key technology for strategic development to replace existing traditional lighting equipment. Of course, in addition to general household lighting equipment, street lamps under the management of administrative agencies are listed as the main target for giving priority to the use of LEDs. [0003] Such as figure 1 As shown, the existing LED lighting equipment is to electrically connect a plurality of LED elements 1, 2, and 3 that can respectively emit red light, green light, and blue light to a circuit board 4, and then the circuit board 4 is connected t...
