Portable lighting device capable of carrying out long-distance size measurement

Abstract

The invention discloses a portable lighting device capable of carrying out long-distance size measurement. The device comprises a cylinder, a ranging probe and the like; the ranging probe and an LED lamp bead are arranged at the front end of the cylinder body; an illumination switch key, a ranging key and a display screen are arranged on the side surface of the cylinder body; a range finder and abattery are arranged in the cylinder body; the range finder is connected with the ranging probe and the battery, a lens is arranged in front of the LED lamp bead, scales are arranged on the LED lamp bead, an integrated circuit board used for calculating the size of a light spot irradiated to a target by the LED lamp bead is arranged in the cylinder body, and the integrated circuit board is connected with the range finder, the display screen and the battery. According to the invention, the optical principle is utilized, the irradiated output light spot is used as a scale, the size of a long-distance target object is measured, and the distance and the size are converted and directly displayed by using an integrated circuit, so that the size of the long-distance target object can be rapidly and accurately measured while the illumination function is met, and the device is simple, portable and relatively high in functionality.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to a portable lighting device capable of long-distance dimension measurement. Background technique [0002] Portable lighting equipment, also known as handheld lighting equipment, is widely used in many special scenarios such as outdoor adventure sports, military and police search and rescue, and lighting in confined spaces. At present, most commonly used lighting equipment uses LED lamp beads as its light source. Lamp beads have the advantages of low cost, long life, low heat generation rate, and stable performance. [0003] In recent years, with the rapid development of public infrastructure construction, more and more underground projects have been constructed and put into use. Due to the particularity of underground projects, the lighting conditions are usually poor. Therefore, during the construction and operation of underground projects, portable Lighting equipment often bec...

Problems solved by technology

However, due to the long distance of the target (such as the distance on the vault, etc.), it is difficult to measure (the total station can be used for measurement, but it is inconvenient to carry, and it is too professional, so it is difficult to master). In reality, these dimensions are generally estimated through experience Therefore, the error is often large
