Description

LED lights for large lighting venues

technical field

The utility model relates to an LED lamp, in particular to an LED lamp used for large-scale lighting places.

Background technique

In the lighting of some large places such as factories, shopping malls and tunnels, many traditional incandescent lamps are still used as light sources. This solution not only consumes a lot of electricity, but also has a shorter service life and higher maintenance costs. LED is a cold light source, which can alleviate human visual fatigue and improve human comfort when it is actually used in high bay lights/flood lights/tunnel lights, and can save a lot of electric energy without heat radiation.

However, the high bay lights/flood lights/tunnel lights commonly used in the market are all-in-one luminaires with non-adjustable angles. After each luminaire is produced, it must have a fixed installation position to direct the light to the desired place. If you need to adjust the lighting direction, you need to replace the lamp or change the installation location, which brings a lot of inconvenience to the installation and maintenance. Moreover, the lighting is uneven, and there are bright and dark spots, which is easy to cause fatigue and affect work efficiency.

Utility model content

The technical problem mainly solved by the utility model is to provide an LED lamp for large-scale lighting places, and the lighting range can be effectively expanded through the modularized design.

In order to solve the above technical problems, a technical solution adopted by the utility model is to provide an LED lamp for large-scale lighting places, including a suspension rod, a lamp stand and several lamp groups; the lamp stand is rotatably installed on the On the suspender, there are several positioning holes on the light stand, and there are fixing holes on the suspender, and the fixing holes are fixed and matched with different positioning holes to adjust the angle between the light stand and the suspender; the lamp group The two sets of screws symmetrically arranged on both sides are installed in the lamp holder. There are fixed installation holes and arc installation holes on the lamp holder. One of the two sets of screws is installed in the fixed installation hole, and the other is installed in the arc. different positions in the shaped mounting holes to adjust the lighting angle of the light unit.

Wherein, the lamp group includes several LED lamp beads, dust-proof boards and heat sinks, the LED lamp beads are installed on the heat sink and arranged in a matrix, the dust-proof board covers the outside of the LED lamp beads, and the dust-proof A lens is provided in the plate.

Wherein, ventilation openings are opened on the two sides and the top of the installation position of the lamp group on the lamp holder.

Wherein, the lamp holder is further provided with a battery, and the battery is used for connecting a power source and the lamp group.

The beneficial effects of the utility model are: the whole lamp is mainly composed of a lamp frame and a lamp group, the lamp frame can be installed with multiple lamp groups according to the requirements of the illumination, and the whole lamp has two places where the angle can be adjusted, namely the angle of the entire lamp frame and the angle of a single lamp frame. The angle of the lamp group can make the lighting range larger and more uniform by adjusting the lighting angle; and each lamp group can be installed independently, making the maintenance of the entire lamp more convenient.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , this embodiment is an LED lamp for large-scale lighting places, including a suspender 10 , a lamp stand 20 and a lamp group 30 .

The lamp holder 20 is rotatably mounted on the suspender 10, the lamp holder 20 is provided with a plurality of positioning holes 21, the suspension rod 10 is provided with a fixing hole 11, and the fixing hole 11 passes through different positioning holes 21 The angle between the lamp holder 20 and the suspension rod 10 can be adjusted through fixed cooperation with each other.

The lamp group 30 is installed in the lamp holder 20 through two sets of screws 31 arranged symmetrically on both sides. The lamp holder 20 is provided with a fixed installation hole 22 and an arc-shaped installation hole 23. The arc of the arc-shaped installation hole 23 is based on The fixed mounting hole 22 is set at the center of the circle. One group of two groups of screws 31 is installed in the fixed mounting hole 22 , and the other group is installed in different positions in the arc-shaped mounting hole 23 to adjust the lighting angle of the lamp group 30 .

In this embodiment, four lamp groups 30 are arranged in a straight line in the lamp holder 20 . Each lamp group 30 includes twenty LED lamp beads 32 . The LED lamp beads 32 are installed on the heat sink 33 and arranged in a matrix. The outside of the LED lamp beads 32 is covered with a dustproof plate 34 with lenses.
