AI Technical Summary

Technical Problem

Existing portable lamps have limited functionality, providing consistent brightness at both near and far distances. When used for near-distance illumination, the brightness is too high, causing discomfort to the user. Furthermore, they lack versatility.

Method used

The main light source assembly is equipped with a distance sensor and control unit to automatically adjust the brightness of the main light source according to the distance, and is also equipped with side light source assemblies and warning LEDs to meet diverse lighting needs.

Benefits of technology

It achieves automatic adjustment of the main light source brightness according to the distance, providing comfortable lighting at close range, and taking into account lighting needs at both near and far distances, increasing the functionality and safety of the handheld lamp.

Abstract

The application provides a lamp structure and a hand lamp, relates to the technical field of lamps, and solves the problems of single function of the lamp, consistent brightness of the hand lamp in long-distance lighting or short-distance lighting, and poor comfort in short-distance lighting. The lamp structure comprises a lamp cylinder, a main light source assembly and a control unit in the lamp cylinder, the main light source assembly comprises a main light source and a distance sensor, the distance sensor is used for detecting the distance between the main light source assembly and a target obstacle, the control unit is electrically connected with the main light source and the distance sensor, and is used for controlling the power of the main light source to be reduced when the distance between the main light source assembly and the target obstacle is less than a set value. The lamp structure provides the comfort of short-distance lighting for the user and takes into account the long-distance and short-distance lighting requirements. When the lamp structure is placed on the desktop, especially on the surface of flammable objects, the distance sensor senses the obstacle, the power of the main light source is reduced, the temperature of the main light source assembly is reduced, and danger is avoided.
