Low-glare LED projection lamp reflecting module and straight LED projection lamp

Abstract

The invention relates to a low-glare LED projection lamp reflecting module. A reflecting bowl is arranged on a radiator; an LED unit is embedded in the smaller end of the reflecting bowl, and a lens is arranged at the larger end of the reflecting bowl; a shell is arranged at the upper end of the radiator for limiting the lens and the reflecting bowl; the inner wall of the reflecting bowl is a revolving surface formed by rotating an outwards projected arc along a center line of the LED unit; multiple reflecting edges are radially arranged on the revolving surface; and the reflecting edges, theinner wall and the lens cooperate to deviate light rays emitted by the lens. In the low-glare LED projection lamp reflecting module, the light rays treated by the reflecting bowl, the lens and the reflecting edges are deviated by a certain angle, so that the glare index is greatly reduced, and the safety of pedestrians and the driving safety of vehicles are guaranteed; through adjustment of a hinge shaft in one direction of a mounting frame and a hinge shaft in the other direction, convenient disassembly of the reflecting module and adjustment of the illuminating angle can be realized; and thelow-glare LED projection lamp reflecting module is novel low-glare illumination lamp suitable for highways and tunnels.

Description

technical field [0001] The invention belongs to the technical field of structural improvement of special floodlights for highways and tunnels, in particular to a low-glare LED floodlight reflection module and in-line LED floodlights. Background technique [0002] Highway lighting and tunnel lighting require a large number of floodlights. These lamps have high installation height and high lighting brightness requirements. In the past, high-pressure sodium lamps were often used, but these lamps consume a lot of power, generate heat, and have a short service life, which cannot meet the needs of society. The development of energy-saving and environmental protection needs. Through research, some manufacturers apply LEDs to floodlights, and use reflectors and lenses to integrate secondary light sources to improve illumination brightness and illumination distance.

[0002] Highway lighting and tunnel lighting require a large number of floodlights. These lamps have high installation height and high lighting brightness requirements. In the past, high-pressure sodium lamps were often used, but these lamps consume a lot of power, generate heat, and have a short service life, which cannot meet the needs of society. The development of energy-saving and environmental protection needs

Through research, some manufacturers apply LEDs to floodlights, and use reflectors and lenses to integrate secondary light sources to improve illumination brightness and illumination distance. When used, they do meet the design requirements, but these lamps have the following disadvantages : 1. The light emitted by the lamp is integrated with the secondary light source of the reflector and the lens to form a similar linear light source. The irradiation distance increases and the brightness increases, but the glare index also increases, causing passing drivers and pedestrians to have eye damage. Discomfort, especially when driving and walking at night, the light is more irritating to the eyes, which leads to problems such as a decrease in the recognition ability of drivers or pedestrians, which is not conducive to traffic safety; 2. According to national standards, special lamps for roads, tunnels, etc. During maintenance, the lamp module must be able to be replaced separately, but in the existing floodlight, some modules are fixed on the connector or mounting part, which is not easy to disassemble, and although the other part can be replaced independently, the structure involved is too complicated , resulting in a long time-consuming disassembly process or a waste of overall replacement; 3. Among the above-mentioned floodlights, each lamp is a fixed structure, that is, when the projection position and range of the floodlight need to be adjusted, the lamp needs to be removed first, and then The adjustment of the projection angle is completed by using different fixing parts
