LED lamp for outdoor engineering lighting

Abstract

The invention relates to the technical field of outdoor engineering lighting devices and discloses an LED lamp for outdoor engineering lighting. A movable chassis, a lifting table and a telescopic column are included; the lifting table is arranged on the top of the movable chassis; the telescopic column is arranged in the lifting table in a sleeved manner; a bearing block is welded to the top endof the telescopic column; a round disk is installed on the top of the bearing block; four hollow columns are symmetrically distributed on the outer side of the round disk; the upper end and the lowerend of each hollow column are each provided with a bearing; and a hollow pipe is arranged in each hollow column in a sleeved manner. According to the LED lamp for outdoor engineering lighting, due tothe fact that the hollow columns are matched with the hollow pipes, cross connection rods are enabled to complete angle conversion, corresponding LED projection lamps on the four cross connection rodscan rotate to perform adjustment annularly for a good angle, single body area lighting and combined body area lighting are both allowed, illuminance is improved, and variability of the lighting rangeand the practical requirement are improved.

Description

technical field [0001] The invention relates to the technical field of outdoor engineering lighting equipment, in particular to an LED lamp for outdoor engineering lighting. Background technique [0002] Lighting projects include road lighting, urban night scene lighting, indoor lighting, architectural lighting and other projects. Lighting engineering not only has the function of functional lighting, but also has the function of beautifying the urban environment. With the development of social science and technology, the application of LED lamps in lighting engineering is becoming more and more popular. Its energy saving, high brightness, rich colors, strong controllability and other characteristics make LED widely used in lighting engineering.

In order to facilitate the construction and supervision of outdoor projects, it is necessary to place lamps for corresponding lig...

AI Technical Summary

Problems solved by technology

[0003] In the field of engineering and construction, the role of lighting is particularly important. In order to facilitate the construction and supervision of outdoor projects, it is necessary to place lamps for corresponding lighting in the area, but the distribution of the connecting wires between the lamps and the power supply is messy, and the lighting points change with the project. And changes, and the power supply distance in remote outdoor areas is far away, requiring longer wires, which is very inconvenient. In order to use common lamps and lanterns in the market with engines and collectively referred to as outdoor engineering lighting or outdoor lighting vehicles, the engine generates power to provide power and lighting. The lamp is fixed on the top of the bracket, and the lighting range is increased by adjusting the height of the bracket, but it still has the following technical problems

[0004] 1. Due to its fixed-point lighting and fixed lamps, the range of lighting angles is fixed, and the direct illumination range of the lamps cannot be adjusted. The area lighting range can only be adjusted through the lifting platform, which affects practical needs.

[0005] 2. It is easy to move during the use of the outdoor engineering lighting vehicle, but because of the single-sided lighting, when adjusting the direction of the direct light, the entire lighting vehicle needs to be rotated as a whole, which is time-consuming and labor-intensive. Due to the weight of the generator and the frame, the labor intensity of single-person operation is high
