Abstract

The invention discloses a multi-cavity LED street lamp. The multi-cavity LED street lamp comprises a front end cover and a rear end cover which are connected, wherein an independent cavity is formed in each of the front end cover and the rear end cover; the front end cover comprises a front cover and an LED lens, the LED lens is fixed on the front cover to form a closed cavity, and a PCB (printed circuit board) and an LED light source are arranged in the cavity formed by the LED lens and the front cover; the front cover is obliquely arranged to form an included angle with the horizontal plane, and the rear end cover is fixed on the front cover. According to the multi-cavity LED street lamp, the LED light source is obliquely mounted, most of outgoing light of the LED light source is irradiated to a street, the light energy utilization rate of the lamp is greatly increased, the light distribution efficiency is improved, and the optimal illumination is realized. With the adoption of high-voltage, linear and constant-current drive, an addition power supply is not required, the product size and the cost are greatly reduced, and the miniaturization design of the product is facilitated.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting, and in particular relates to a multi-cavity LED street lamp. Background technique [0002] In recent years, due to the development of LED technology, LED lighting has begun to be recognized and adopted by most users. Various LED lamps emerge in an endless stream, and the structure of LED lamps is also diverse. [0003] However, most of the LED light sources in the existing LED street lamps are installed horizontally and irradiate vertically downward. Part of the light emitted by the LED light source is irradiated on the road, and some is irradiated on the side of the house. The light energy irradiated on the side of the house is not fully utilized, resulting in a low light energy utilization rate of the existing LED lamps, and is prone to glare. [0004] Moreover, the existing LED street lamps usually consist of a plurality of LED light source modules, and each LED light source mo...
