Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and more specifically, to an LED spotlight for engineering machinery. Background Technology
[0002] LED spotlights for construction machinery are key lighting equipment for modern construction vehicles (such as excavators, loaders, and cranes), playing an irreplaceable role in low-light environments such as nighttime operations and tunnel construction. To ensure the reliability and optical performance of LED spotlights under complex working conditions (such as vibration, dust, and high / low temperatures), their structural design is particularly crucial.
[0003] The use of a separate mask and optical lens structure in LED spotlights for construction machinery is becoming increasingly mainstream. This structure, through the layered design of an independent mask and an internal optical lens, provides protection for the optical lens when assembled, but it also introduces the following prominent problems:
[0004] 1. Poor structural stability: The working environment of construction machinery is complex and it is in a state of vibration and bumps for a long time. This can easily cause the relative position of the mask and lens to shift, affecting the lighting effect of the LED spotlight.
[0005] 2. Cumbersome assembly: The separate structure of the mask and optical lens increases the assembly process and difficulty, requiring higher technical skills from assembly workers. Furthermore, slight carelessness during assembly may introduce deviations, reducing the production efficiency of LED spotlights.
[0006] 3. Insufficient sealing: The separate structure results in an assembly gap between the mask and the lens. Dust and moisture can enter and contaminate the optical lens, reduce light transmittance, and affect the lighting effect of the LED spotlight. Utility Model Content

This LED spotlight for engineering machinery can solve the problems of poor structural stability and poor sealing caused by the separation of the mask and optical lens, thereby improving the optical performance and lighting effect of the LED spotlight.
[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: an LED spotlight for engineering machinery, characterized in that it includes a rear shell, a lamp panel assembly with a plurality of LEDs, a front frame, and an optical assembly; the lamp panel assembly is disposed inside the rear shell and connected to the rear shell; the optical assembly includes a mask, on which optical lens components are provided in an number equal to the number of LEDs, and the mask and the optical lens components are an integral structure; the mask is connected to the rear shell, each optical lens component covers a corresponding LED, and the light emitted by the LEDs is emitted through the optical lens components and the mask; the front frame is connected to the rear shell and accommodates the lamp panel assembly and the optical assembly inside the rear shell.

To solve the problem of excessive light decay caused by high internal temperature of the LED spotlight, the lamp board assembly 2 of this invention is directly attached to the installation plate 10 inside the rear shell 1 near the heat sinks 9 using fastening screws. By rationally designing the structure of the heat sinks 9 in the rear shell 1, such as increasing their height and thickness, the surface heat dissipation area is increased.

The rear shell is adjustablely connected to the mounting bracket, and the engineering machinery LED spotlight can be installed at an adjustable angle via the mounting bracket. Specifically, the mounting bracket includes a bracket 12, a bolt 13, and a locking assembly 14. The rear shell 1 is connected to the bracket 12 via the bolt 13 and its angle can be adjusted up and down.
