Problems solved by technology

[0004] 2. In order to solve the defect of the short luminous time of the fluorescent layer, a light source is usually installed on the information display corresponding part of the display device. In order to satisfy the long-term work of the light source, it must be powered by an external power supply. This is obviously inappropriate for clocks and watches that require low cost. Moreover, it will inevitably increase the conditions of use and cost of use of the corresponding products.

Embodiment 1

[0022] Such as figure 1 with figure 2 A fluorescent quartz wall clock with built-in supplementary light is shown, which is provided with a display part 1 and a light sensor; the display part is provided with a fluorescent layer 4 at a position corresponding to information display; a reflective cup is provided on the back of the display part of the display device 5. A light source 2 is installed in the reflective cup 5, so that the light projected by the light source 2 on the information display position is first projected on the fluorescent layer 4; the light source 2 is connected with a control device that can control the light source to turn on and off alternately.

[0023] The display part is provided with a transparent light guide plate 3 at the position where the information is displayed, and the light guide surface 31 of the light guide plate 3 faces the light source 2; the fluorescent layer 4 is arranged on the other side 32 of the light guide plate 3 relative to the ...

Embodiment 2

[0040] For a fluorescent quartz wall clock with built-in supplementary light as described in Example 1, its control device can also adopt the following scheme.

[0041] Such as figure 2 The control device for controlling the light source to turn on and off alternately includes a gear 1, a control switch 2 and a control circuit 3; the control switch 2 is formed by connecting an inverted V portion 2A and an inverted V portion 2B and has an inverted W structure, and the inverted V There is a fulcrum 20 at the junction of the parts 2A and 2B, so that the control switch 2 can swing around the fulcrum 20, and the other foot of the inverted V part 2A is provided with a magnetic metal sheet 22 relative to the junction 20, and the inverted V part 2B is opposite to the connection. The other foot at 20 is provided with a magnetic metal sheet 23; the control circuit 3 is provided with a magnetic electric key 31 located below the metal sheet 23, as image 3As shown, the magnetic key 31 i...

Abstract

The invention provides a fluorescent display device with built-in supplementary light, which is provided with a display part; the display part is provided with a fluorescent layer at a position corresponding to information display; and the back of the display part is provided with one or more light sources, so that The light projected by the light source onto the information display position is first projected on the fluorescent layer and emitted from the fluorescent layer; the light source is connected with a control device that can control the light source to turn on and off alternately. The present invention sets a light source, a fluorescent layer and a control device; the first stage: when the light source is bright, part of the light emitted by the light source is absorbed by the fluorescent layer, and part of it is emitted from the fluorescent layer, so that the graphic information on the fluorescent layer is visible . The second stage: when the light source is turned off, the fluorescent layer remains bright; the control device simultaneously controls the light source to turn on the light source again before the light projected by the fluorescent layer is not visible enough to carry out the first stage; make the first stage and the second stage The two stages are carried out continuously and alternately to realize the persistent visibility of information; since the light source does not need to work for a long time, the power consumption is significantly reduced, which greatly prolongs the service life of the display device and the battery.

Description

technical field [0001] The invention relates to the field of clocks or guide devices, in particular to a clock or guide device that can keep information visible even in an environment with poor light. Background technique [0002] It is not easy to see the displayed information of traditional clocks or guiding devices at night. There are usually two solutions to this problem: [0003] 1. Only set the fluorescent layer on the corresponding position of the information display of the display device. By absorbing light or external light sources, the fluorescent layer can be illuminated. This method cannot maintain enough light energy for a long time due to the limited light energy absorbed by the phosphor powder. Visible light captured by the naked eye, which in turn makes information on clocks or guides invisible. [0004] 2. In order to solve the defect of the short luminous time of the fluorescent layer, a light source is usually installed on the information display correspo...
