Outdoor LED lamp

Abstract

The invention discloses an outdoor LED lamp which comprises a power source, an upper cover, a radiator, a lower shell and a light source base plate. The light source base plate and the lower shell are connected by a rubber telescopic sleeve, and the side surface of the telescopic sleeve is a wave-shaped pleat; a plurality of through holes arranged in an annular array are formed in the side surface of the telescopic sleeve; and four sets of adjustment rods arranged in an annular array mode are disposed in the lower shell, the adjustment rods include outer rods, magnetic pieces and inner rods, electromagnetic coilsare disposed in the outer rods, the magnetic pieces are connected with the inner rods, and the inner rodsare rod members prepared from a shape memory alloy material. The outdoor LED lamp uses the rubber telescopic sleeve to play a good sealing effect on the light source and uses the shape memory alloy material to open the ventilation after the temperature rises, so that the influence of external water vapor, dust and the like on the interior of the lamp isreduced, and the service life isprolonged; and by utilizing the ductility of the telescopic sleeve and an electromagnetic control structure, the steering of the light source can be controlled, and the problem of fixing the illumination direction of an ordinary lamp is solved.

Description

technical field [0001] The invention relates to the related field of LED lighting fixtures, in particular to an outdoor LED lighting fixture. Background technique [0002] At present, with the continuous development of the industry, breakthroughs in technology, and vigorous promotion of applications, the luminous efficiency of LEDs is constantly improving, and the price is constantly falling.

AI Technical Summary

Problems solved by technology

[0003] LED lamps are also widely used in outdoor lighting, indication, etc., such as industrial and mining lamps and spotlights that can provide powerful lighting effects. The above-mentioned lamps are used outdoors, and the use environment is relatively harsh. Because they are more affected by the external environment, the service life is usually difficult to reach. Ideal effect, frequent repairs and replacements of lamps and lanterns will generate a large cost of manpower and material resources

In addition, the lamps used for lighting are usually installed and fixed, and the lighting angle is also fixed. For some lighting such as factory buildings, when the lighting angle needs to be changed, only multiple groups of lamps can be added to cover, which increases the lighting cost.
