Abstract

The utility model relates to a yellow light healthy desk lamp with a captions displaying device. The yellow light healthy desk lamp with a captions displaying device is composed of a lamp holder, a lamp arm, a lampshade, a switch, a rectifying filter circuit, an intermission control circuit, a captions lamp, a captions display board, allochroic slices, etc. The intermittent on-off of the captions lamp is controlled by the intermittent control circuit. Therefore, captions can be intermittently displayed by the captions display board, which supplies resting time for a learner. The lower part of the lampshade is provided with the yellow allochroic slices, the desk lamp of the utility model can emit soft yellow light, and the fatigue of the eyes can be lightened. The utility model can protect the vision and can improve the efficiency of a brain. The utility model has the advantages of simple circuits, low cost and practical functions. The utility model is a late-model desk lamp with wide prospect.

Description

Yellowlight healthy desk lamp with captions displaying device

The utility model relates to a kind of desk lamp, particularly a kind of gold-tinted health desk lamp with the captions demonstration.

Disclose a kind of eye health care lamp of automatic change color in the Chinese patent (patent No. 87207946), it is formed by becoming optical circuit, rectification circuit, bleeder circuit, delay circuit, electronic switching circuit and music circuit etc.The used element of this health care lamp reaches dozens of, exists complex process, shortcomings such as volume is excessive, cost is higher, performance shakiness.

The purpose of this utility model be to avoid above-mentioned the deficiencies in the prior art part and provide that a kind of circuit is simple, gold-tinted health desk lamp that novel structure, band word with low cost show.

The purpose of this utility model can reach by following measure: the utility model comprises lamp socket, arm, lampshade, switch, current rectifying and wave filtering circuit, illuminating lamp, it is characterized in that: also have intermittent control circuit, captions lamp, captions display board, variable color sheet, intermittent control circuit is delivered in the output of current rectifying and wave filtering circuit, the captions lamp is delivered in the output of intermittent control circuit, the captions lamp is loaded in the lamp socket, and correspondence position is equipped with the captions display board on the lamp socket.The variable color sheet is a yellow light-passing plastic sheet, is contained in the lampshade lower edge.The output of current rectifying and wave filtering circuit meets potentiometer W in the intermittent control circuit by R1, R3, D6,2,6 pin of the mid point of W and capacitor C 4 and IC 1 join, 3 pin of IC 1 connect the control grid G of controllable silicon SCR by resistance R 2, and the anode F of SCR, negative electrode E connect with the captions lamp.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a contour structures schematic diagram of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:

With reference to Fig. 1, Fig. 2, the utility model is made up of lamp socket 1, arm 2, lampshade 3, switch 4, current rectifying and wave filtering circuit 5, illuminating lamp 6, intermittent control circuit 7, captions lamp 8, captions display board 9, variable color sheet 10 etc.Captions lamp 8 is contained in the lamp socket 1, and (place corresponding with the captions lamp) is equipped with captions display board 9 on the lamp socket 1, is carved with " please be the strong behaviour of eye newspaper " printed words on the board.Variable color sheet 10 is yellow light-passing plastic sheets, be contained in the lower edge of lampshade 3, make illuminating lamp 6 can send soft sodium yellow, learn from physiology, people's eyes are the most responsive to yellow, vision is the most clear under yellow light, and can keep color sense preferably, plays the health-care effect that alleviates eye fatigue.

With reference to Fig. 3, when closing a switch 4 connection power supplys, illuminating lamp 6 is bright, sends soft sodium yellow by the variable color sheet; Simultaneously, the anode of capacitor C 4 is low level, and 2,6 pin of IC 1 are low level, 3 pin output high level, and captions lamp 8 is lighted; Meanwhile power supply charges to C4, and the voltage on C4 is charged to 1/3V _CCThe time, IC 1 is in reset mode, and promptly 3 pin jump to low level by former high level, and captions lamp 8 extinguishes; When the C4 both end voltage drops to 1/3V _CCThe time, make IC 1 be in SM set mode, 3 pin are exported high level again, and captions lamp 8 is bright.So constantly charge and discharge, thereby captions lamp 8 is intermittently lighted.Regulator potentiometer W can regulate the charge and discharge time ratio of C4, and this example is adjusted to 5:1.The model of IC 1 is NE555.

Actual use is: when desk lamp was opened in student's study, captions nameplate 9 promptly showed " please do eye exercises ", and at this moment, the student should carry out preceding the loosening of study, progresses into learning state.After 10 minutes, captions extinguish, and can learn.After 50 minutes, the captions lamp shows that the student should stop study, loosens rest, relieving fatigue.After 10 minutes, the captions lamp goes out, and rest finishes, and can learn.So circulation is struck a proper balance between work and rest eyes, the effect that reach vision protection, improves the efficient of requiring mental skill.

The utility model has following advantage compared to existing technology:

1. can automatically show captions, the time that the prompting learner has a rest, can send soft gold-tinted again, alleviate the fatigue of eyes, reach vision protection, improve the effect of the efficient of requiring mental skill.

2. circuit is simple, and is rational in infrastructure, and the function practicality is a kind of very promising novel reading lamp.
