Abstract
The utility model provides a kind of projection clock, comprise shell, single-chip microcomputer, clock chip, LED display, it is characterized in that: in described shell, be provided with single-chip microcomputer, projection lamp and battery, shell is provided with light activated element, described light activated element, clock chip, projection lamp are all connected with single-chip microcomputer with battery, described LED display is arranged on shell front side, described projection lamp is arranged on LED display top, it is described when light activated element senses dark, signal is sent to single-chip microcomputer, is worked by Single-chip Controlling projection lamp; Also shown by LED display screen by projection lamp display after the time signal of acquisition is sent to single-chip microcomputer process by clock chip simultaneously.The utility model compared with prior art has significant advantage and beneficial effect: just can open projection lamp when dark, energy saving.
Description
Technical field
The utility model relates to electronics field, particularly a kind of projection clock.
Background technology
Clock is all generally pointer, people directly see the time by pointer, occur that projection lamp and electronics LED show clock now, this clock is by projection lamp and LED display displaying time, but projection lamp and LED display screen compare power consumption, the hot spot effect projected out when light is strong daytime is bad, not as directly checking LED display, how long battery is have more than is needed will change, be unfavorable for saving the energy, if a kind of display when dark can be there is, just can solve this problem.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of projection clock of energy saving.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of projection clock, comprise shell, single-chip microcomputer, clock chip, LED display, it is characterized in that: in described shell, be provided with single-chip microcomputer, projection lamp and battery, shell is provided with light activated element, described light activated element, clock chip, projection lamp are all connected with single-chip microcomputer with battery, described LED display is arranged on shell front side, described projection lamp is arranged on LED display top, it is described when light activated element senses dark, signal is sent to single-chip microcomputer, is worked by Single-chip Controlling projection lamp; Also shown by LED display screen by projection lamp display after the time signal of acquisition is sent to single-chip microcomputer process by clock chip simultaneously.
The utility model compared with prior art has significant advantage and beneficial effect: just can open projection lamp when dark, energy saving.
Accompanying drawing explanation
Fig. 1 is principle assumption diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, feature and effect thereof of providing according to the utility model, be described in detail as follows.
A kind of projection clock as shown in Figure 1, comprise shell, single-chip microcomputer, clock chip, LED display, it is characterized in that: in described shell, be provided with single-chip microcomputer, projection lamp and battery, shell is provided with light activated element, described light activated element, clock chip, projection lamp are all connected with single-chip microcomputer with battery, described LED display is arranged on shell front side, and described projection lamp is arranged on LED display top.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
