LED light source and floodlight with adjustable light angle

Abstract

The invention provides an LED light source with the adjustable light angle. The LED light source comprises a housing, a cover, an LED circuit board, a cylindrical connecting seat and a cylindrical mounting seat. One end of the connecting seat is provided with a connecting portion extending axially, the connecting portion is fixedly connected to the housing, one end of the mounting seat is provided with a mounting portion extending axially, and the mounting portion is used for fixedly connecting with a light head; the other end of the mounting seat is provided with an accommodating cavity, the connecting seat is located in the accommodating cavity, the other end of the connecting seat is provided with an accommodating groove with one opening facing to the mounting seat, the outer wall of the accommodating groove is provided with a cycle of rotating tooth surface, a rotating member arranged in the accommodating groove is arranged in the accommodating cavity, and the outer circumference of one end of the rotating member is provided with radially-protruded rotating teeth engaged with the rotating tooth surface. After the LED light source is fixed in the housing of a floodlight, the LED light source is capable of rotating corresponding to the light head by rotating the housing, the irradiating angle of the light emitted from the LED circuit board can be adjusted, and the irradiating requirements of different occasions can be met accordingly.

Description

technical field [0001] The invention relates to an LED light source, in particular to an LED light source and floodlight with adjustable light angle. Background technique [0002] Luminaires refer to appliances that can transmit light, distribute and change the light distribution of the light source, including all parts required to fix and protect the light source except the light source, as well as the necessary line accessories for connection to the power supply. Lamps have been developed to have a variety of different specifications and types, which can be used for home lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, special lighting, etc. At present, there are mainly two types of lamps used for commercial lighting and industrial lighting: floodlights and spotlights; among them, floodlights are a kind of lamps that can illuminate uniformly in all directions, and its irradiation range can be adjusted arbitrarily, which is represented ...

AI Technical Summary

Problems solved by technology

But there is following defect in the floodlight adopting mercury lamp: 1, mercury lamp is ellipsoid, and it can emit light at 360 degrees, but reflector can only reflect most of light to required irradiation range, and some The light cannot be reflected, resulting in the loss and waste of part of the light; 2. The power of the mercury lamp is relatively high, it is not energy-saving, and mercury is a harmful substance, which will cause environmental pollution

However, the LED floodlight cannot adjust the irradiation angle and reflection angle of the light emitted by the LED light source, so there are great limitations in actual use.
