Example Embodiment

[0032] The outdoor lighting device according to the exemplary embodiment is described in detail below with reference to the accompanying drawings.

[0033] figure 2 It is a schematic block diagram showing a light source driving circuit according to an exemplary embodiment. Such as figure 2 As shown in, the light source driving circuit according to the exemplary embodiment includes a rectifying bridge circuit 1, a voltage adjusting circuit 2 and a light emitting diode driving source circuit 3.

[0034] The input terminal of the bridge rectifier circuit 1 is connected to an external power source. The external power source is, for example, a commercial power source or other AC power source with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 110V or 220V. The bridge rectifier circuit 1 converts an AC voltage supplied from an external power source into a DC voltage. The rectifier bridge circuit 1 provides the rectified first output to the voltage regulation circuit 2 thr...

Abstract

The invention provides an outdoor lighting device. The outdoor lighting device includes: a light source driving circuit board, on which a light source driving circuit is arranged; a light source board, on which a light emitting diode light source electrically connected to the light source driving circuit is installed, and the light emitting diode light source A plurality of light-emitting diodes are included, and the plurality of light-emitting diodes include small light-incidence-angle light-emitting diodes. The outdoor lighting device has the advantages of simple structure, low micro-current power consumption, no heat generation, strong anti-interference ability to power supply, explosion-proof function, long life without maintenance, good versatility, low cost, long-term lighting does not affect eye health, etc., mainly The performance parameters meet the requirements of relevant national standards, and the produced light-emitting diodes with small beam angles can be used in the lighting system, which greatly reduces the production cost and does not need to discard the light-emitting diodes with small beam angles.

Description

technical field [0001] The present invention relates to the lighting field, and more specifically, the present invention relates to an outdoor lighting device. Background technique [0002] A light-emitting diode light source is a light source including one or more light-emitting diodes (LEDs). Due to the high luminous efficiency and long life of the light-emitting diodes, the light-emitting diode light source has attracted much attention as a next-generation lighting device. By selecting various parameters of the LEDs included in the LED light source and the number of LEDs, it is possible to realize LED light sources with brightness meeting various needs and different powers. For example, light-emitting diode light sources can be used as various lighting devices such as ceiling lamps, table lamps, long tube lamps for indoor lighting, and street lamps for outdoor lighting. [0003] In the existing process of manufacturing light-emitting diodes, due to the influence of vario...
