Abstract

The invention relates to a writing lamp with eye care effect, small size, light weight and high luminous efficiency. A group of high-performance white LEDs are assembled in a lightweight lamp holder, and the lamp holder is mounted on a head lantern ring which can be worn on the head of a user; and the power supply of the group of the LEDs is realized through a DC power supply device, thereby leading the lamp holder to irradiate in the direction which is the same with the visual line of the user.

Description

Technical field [0001] The invention relates to a lighting device, in particular to a lamp for health care lighting for writing and writing. Background technique [0002] At present, known writing lamps or desk lamps are all desk-mounted devices. Due to their structure, volume, weight and other factors, they can only be placed somewhere in front of the writing position during work. In this way, part of the direct light and most of the reflection of the light will inevitably be projected on the eyes of the user, which will not only interfere with the line of sight, but also affect the health of the eyes and endanger the health of the eyes. Therefore, it is necessary to develop a small, light, convenient and economical lamp with high luminous efficiency to replace the existing writing lamp or desk lamp. Contents of the invention [0003] In order to realize the health care function of writing lamps or desk lamps, and replace existing desk lamps with a small, light, convenie...
