Abstract
A health desk lamp for students belongs to illumination appliance. The framework comprises the illumination part and specific infrared surveillance system. The utility model takes advantage of the body surface reflection of infrared ray and the infrared photosensitive device characteristic of ambient light to percept the user head position and the ambient light intensity, and reacts by the means of acoustic and light. Thereby, the read-write ambient light intensity is reminded for the user, the user can pay attention the distance between eyes and book whether optimized on not and seated position whether is normal or not, etc. Therefore, the utility model has benefit for wide teenagers preventing myopia, protecting the vision and guarantying vertebra normal growing.
Description
The invention belongs to lighting apparatus.
Lighting lamp in the past, its function mostly are only limited to illumination and use.Adolescent student keeps suitable distance and proper sitting posture for vision protection with guarantee that the normal development of health vertebra all has important function when bending over the desk to learn between adapt circumstance light intensity, eyes and books.Though the invention that Chinese patent CN 85 2 0127U are provided has the lamp source brightness of mirror scaffold tower and monitors the effect of the protection eye eyesight of read-write posture; but as can be seen by its structure; there is following problem in it: at first; the function that this device has only is the brightness of mirror scaffold tower lamp source; and, particularly then do not have any mirror survey effect for the ambient light brightness of not using desk lamp when illumination for ambient light brightness.In order to reach the purpose that monitors user's read-write posture on the preferable daytime of light condition, still must make desk lamp connect electrical source luminescent.On the meaning of illumination, this is a kind of waste.Secondly, for constituting the warning light path that monitors user's read-write posture, this device has been installed light launcher arm and light-receiving arm respectively in its illuminating lamp both sides.This not only makes trouble, and adjusts when using also inconvenient.Simultaneously, two arms stretch out longlyer during this device work, and it is bigger to take up room, neither attractive in appearance, inconvenient again.Again because these two arms are nearer apart from user's head left and right sides, so hinder the normal activity of user's head when study and the action of upper limbs easily.In addition, the function of the supervision read-write posture that this device had means and monitors user's eyes and write distance between table top, and during the situation of, head amesiality long period twisted to user's sitting posture, then do not have any supervision effect.The function of the supervision read-write posture that thus, this device had is incomplete.
The students ' health desk lamp then can solve above-mentioned several problem preferably.The objective of the invention is provides a kind of simple in structure, health desk lamp that function is more complete, handsome in appearance, easy to use for vast adolescent student.It can throw light on and can be when the user bends over the desk to read and write monitoring of environmental light power, and monitor user's read-write posture correctness simultaneously.The distance of the eyes that said here read-write posture comprises the user and read-write books and table top with and whether sitting posture twisted, head whether left or right undue deflection etc.
Accompanying drawing is one embodiment of the present of invention.
As seen from the figure, base (1) is arranged in its structure, support (2), lamp holder (3) and power switch (4), the sensing head (5) of infrared emission device (6) and infrared light sensing device (7) is housed in addition.Adjusting lever (8) one ends connect support (2), and the other end connects sensing head (5).Adjusting lever (8) is connected with sensing head (5), and adjusting lever (8) can be adjusted with support being connected all of (2).Adjustment is undertaken by securing member (10), (11).The infrared signal that makes infrared emission device (6) on the sensing head (5) launch by adjustment can be in preferable states in the direction and the position in space.Functional switch (9) is used for control provides the power supply of electric energy to infrared emission device (6) and infrared light sensing device (7) access and disconnection.Electric part of the present invention has increased the infrared position detecting circuit that has functional switch (9) than the general illumination desk lamp.This circuit comprises several parts such as emission, reception, amplification, time-delay, warning and power supply.
Whether operation principle of the present invention mainly can receive the infrared signal of the CF that reflects through user's head forehead that is sent by infrared emission device (6) of sufficient intensity by infrared light sensing device (7), and after Circuits System of the present invention is handled and whether pick out the power, user's read-write posture of ambient light correct etc.By alarm appliance, make corresponding reaction at last as loudspeaker and light emitting diode.The present invention improves the receiving sensitivity of infrared light sensing device (7) by the brightness of its illuminating lamp, thereby makes more perfect function of the present invention.
The present invention in use, and is the same with the general lighting desk lamp, places user the place ahead to write on the table top usually.Make sensing head (5) apart from user's forehead 400 millimeter by adjustment, apart from writing table top 350 millimeter.Simultaneously, the signal that infrared emission device (6) is sent gets final product near pointing to user's forehead middle part.
Because the present invention is the infrared signal of sending by means of the infrared emission device (6) that is installed on the sensing head (5) to the supervision of user's read-write posture and the monitoring of prevailing circumstances light, rather than the light that sends from the lighting bulb of installing on one's body of the present invention, so, on the daytime of indoor light abundance, need not make the lighting bulb electrified light emitting of the present invention also can operate as normal.And, because transducing part of the present invention is a sensing head (5) with infrared emission device (6) and the adjoining installation of infrared light sensing device (7), so that the present invention has is simple in structure, easy to manufacture, occupy the characteristics that the space is little, handsome in appearance, use is easy to adjust.Again because work of the present invention is based on reflective infrared position probing principle, so, have be quick on the draw, monitor accurately, monitoring range is wide, the advantage of stable performance.It can monitor the distance of user's eyes and its read-write table top, can monitor unfavorable conditions such as whether too twisted user's sitting posture again.For normally rocking of user's head, the normal activity of parts such as wrist, upper arm does not have any obstruction and influence.
Therefore, of the present invention applying for the pre-myopia prevention of vast adolescent student, vision protection, the normal development of assurance vertebra, promotes strong and handsome growth to have very useful effect.
