Combined type LED road lamp

Abstract

The invention relates to a modular LED street lamp, which comprises LED lamps (1), substrates (2), circuit boards (3) and soleplates (4), wherein, pins (1.1) of the LED lamps (1) are connected with the circuit boards (3); and the circuit boards (3) are fixed on the soleplates (4). The invention is characterized in that the substrates (2) comprise a plurality of circular staircase slopes (2.3) which are arranged eccentrically from the periphery to the center to form a spherical structure. The substrates (2) are connected fixedly with the soleplates (4); a plurality of LED lamps (1) are provided and are densely arranged on the circular staircase slopes (2.3) of the substrates (2) in a radial pattern; and the LED lamps (1) are vertical to the substrates (2) at the corresponding positions. Each substrate (2) consists of a substrate I (2.1) and a substrate II (2.2), wherein, the middle part of the substrate I (2.1) has a plane structure, and the substrate II (2.2) is embedded in the plane structure of the substrate I (2.1). The modular LED street lamp of the invention has the advantages of wide range of irradiation, strong illumination and easy production and installation.

Description

(1) Technical field [0001] The invention relates to a street lamp, in particular to a combined LED street lamp. (2) Background technology [0002] A light-emitting diode (LED) is a high-efficiency solid-state light source that can emit light with weak electric energy. The main advantages of LED lighting are environmental protection, long life, energy saving, and will not produce gases that pollute the environment. Under the same brightness, the power consumption of LED lamps is only 1 / 10 of that of ordinary incandescent lamps, but the life span can be extended nearly 100 times. And it can provide tens or even more than 100 hours of continuous lighting. In traditional street lamps of this kind, the arrangement of LED circuit boards in the lampshade is generally planar. This kind of street lamps with LED circuit boards arranged in a plane can only irradiate light under the street lamps, and the lighting area is narrow. The length of the road requires more street lamps, and ...

Problems solved by technology

Chinese patent CN1873294A discloses a combined wide-angle LED lighting lamp and its manufacturing method, which is characterized in that a plurality of LEDs are formed into a spherical shape, and the LEDs form a scattering angle, which is to install the LEDs on the same plane. The disadvantage is that the LED needs to be fixed at a certain angle during installation, and the installation and production are more troublesome
