Description

Energy-saving LED wide-angle substrate lamp for elevator

Technical Field

The utility model relates to the technical field of elevators, in particular to an energy-saving LED wide-angle base lamp for an elevator.

Background

The elevator is a vertical elevator powered by a motor, is provided with a box-shaped nacelle, is the most common vertical transportation vehicle in modern high-rise buildings, is used for carrying people or goods in multi-story buildings, saves time and physical strength of people, and provides convenience for daily life.

However, as a mechanical device, an elevator has a possibility of failure. In case of a failure of the elevator, a user who is riding the elevator is trapped therein, and thus an escape opening needs to be provided in the elevator. In the prior art, the position of the escape opening arranged on the elevator generally collides with the LED lamp tube on the elevator, so that the LED lamp tube covers the escape opening. When the elevator breaks down, the possibility of casualties is greatly increased because the escape opening cannot be fully utilized.

In addition, in the current sedan-chair top structure of elevator, the space is very narrow and small, and when using current ordinary LED fluorescent tube, the illumination brightness of the fluorescent tube under is the biggest, and the illumination brightness at fluorescent tube edge is dim very much to lead to the LED fluorescent tube among the prior art can't illuminate whole car. If the lighting range is expanded and a plurality of LED lamps are installed in the car, the manufacturing cost is increased and the resource is wasted.

Disclosure of Invention

The utility model does not solve the problems, thereby providing an energy-saving LED wide-angle substrate lamp for an elevator.

The utility model relates to an energy-saving LED wide-angle substrate lamp for an elevator, which comprises a PCB (printed circuit board) and a plurality of LED particles;

the LED particles are respectively arranged on the surface of the PCB, and a diffusion lens is arranged on the outer side of each LED particle.

Preferably, the PCB circuit board is coated with a waterproof coating.

Preferably, the diffusing lens is sandblasted.

The utility model also provides an energy-saving LED wide-angle substrate lamp for the elevator, and the solution is as follows: the LED particle connector comprises a wiring port, wherein the wiring port is arranged on the surface of a PCB circuit board, and each LED particle is connected with an external power supply through the wiring port.

Preferably, the PCB circuit board is provided with a constant current chip, one end of the constant current chip is connected with the LED particles, and the other end of the constant current chip is connected with the wiring port.

Preferably, the wiring port is a 4-core wiring port.

Preferably, the plurality of LED particles are arranged at equal intervals.

The beneficial effects of the technical scheme are as follows:

by arranging the diffusion lens outside the LED lamp, the illumination range is increased under the condition that the quantity of LED particles is not increased, and the energy-saving effect is achieved.

In addition, because the volume of this technical scheme is less, setting up elevator escape opening, lighting apparatus can not cover escape passage.
