Description
Technical field
The present invention relates to field of lamp illumination, in particular to a kind of double-lamp cap desk lamp of adjustable angle.
Background technique
Desk lamp currently on the market substantially all use a lamp cap, lamp cap height it is almost the same in the case where, lamp cap its
Illumination region be also it is relatively-stationary, therefore, existing desk lamp in use, cannot adjust lamp according to user's use demands
Head illumination region, when user needs illumination region big can exist illumination dead angle, even if by increase desk lamp height come
The illumination region of lamp cap is adjusted, this illuminating effect will lead to that illumination is dimmed and uneven, and illuminating effect is poor, damage user's eye
Eyeball can not also be adjusted when user needs illumination region small, largely effect on work, study, rest, be inconvenient,
It can be seen that there are larger defects for the design of existing desk lamp, lamp cap cannot be adjusted according to user's use demands and meets user's habit
Used suitable illumination region, application range are very narrow.
Based on the above issues, the patent application of CN104948982A discloses a kind of two-burner lamp adjusting desk light, two
Lamp cap is that two lamp caps, which can be rotated up and down to adjust, realizes opening for its up and down direction on face-to-face, the upper and lower hinged lamp stand in arrangement ground
It closes, thus the illumination region of adjustment lamp cap, but the structure of this two-burner lamp up and down, illumination region can only be adjusted in longitudinal direction
On range, do not meet use habit of the user in left and right directions on (right-hand man), and the lighting area on this longitudinal direction
Domain is adjusted, and arrives larger angle if adjusted, and illumination is easy to shine directly into user's eye upward outwardly, causes eye wounds etc.
Injury, the practicability is poor；The patent application of CN207422027U discloses a kind of lighting device, and it is suitable for night works, maintenance
Repairing etc., although two lamp cap is left and right arrangement, but lamp cap connects connecting piece of lamp cap for swing, and it is illuminated
Direction is outwardly.
In order to overcome the shortcomings of the prior art, that the present invention provides a kind of illumination regions is adjustable, have wide range of applications,
Meet that user's habit, structure be simple and the double-lamp cap desk lamp of the adjustable angle of components layout modules.
Summary of the invention
