Description

Desk lamp

The utility model relates to a kind of life ligthing paraphernalia, particularly a kind of desk lamp.

Existing desk lamp generally has only illuminating effect, and function is comparatively single, can not appreciate as potted landscape.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and both can throw light on, again the desk lamp that can view and admire as potted landscape.

The purpose of this utility model reaches like this: light modulation, speed governing electronic device and transformer etc. are formed master component, form power-supply controller of electric by potentiometer, microswitch etc., add an immersible pump, the common circuit part of forming, adopt low pressure, bulb miniature, adjustable brightness to become possibility thereby make, pea lamp can be through an ingenious part that is arranged as the mountain potted landscpe.

Fig. 1 is the utility model primary structure figure, and as Figure of abstract.

Fig. 2 is main circuit figure of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.

Desk lamp mainly is made up of with lamp socket and circuit part that mountain stone (3) is formed bulb (1), pallet (2).Circuit part mainly comprises master component (4), power-supply controller of electric (5) and immersible pump (6).Master component is by a ₁, b ₁, c ₁And d ₁Form alignment circuit, a ₂, b ₂, c ₂And d ₂Form light adjusting circuit, a ₁, a ₂Be the bidirectional triode thyristor more than the 50W, b ₁, b ₂Be 0.15 μ F overvoltage protection electric capacity, c ₁, c ₂Be current-limiting resistance, resistance is 100k Ω, d ₁, d ₂Be the controllable silicon diac.Transformer f is 50W, transformation ratio 220V/12V.Power-supply controller of electric mainly comprises miniature potentiometer e ₁, e ₂With switch g ₁, g ₂Utilize bidirectional triode thyristor a ₁, a ₂Make voltage regulation component, with miniature potentiometer e ₁, e ₂Regulate the SCR control electrode potential, can Linear Control its two-way admittance angle size, i.e. output voltage size.Alignment circuit is directly controlled the input voltage of immersible pump; Light adjusting circuit is then controlled the brightness of bulb.

As the g that closes ₁Or g ₂The time, supply voltage is added on a ₁Or a ₂Two ends, trigger current is through c ₁Or c ₂, e ₁Or e ₂, d ₁Or d ₂Enter a ₁Or a ₂The control utmost point.a ₁Or a ₂Conducting also forms load current, and angle of flow size is by e ₁Or e ₂The decision of variable resistance, directly start immersible pump or through the indirect starter lighting of transformer f.If trigger voltage is higher than allowed band, b ₁Or b ₂Discharge is the overvoltage protection state.Because of a ₁, a ₂Conducting makes f obtain primary voltage, secondary voltage starter lighting, and its brightness changes with the primary voltage size.

Master component can be put sealing in the plastic casing into, places the holder basin bottom together with immersible pump, and power-supply controller of electric can be installed in the beneath side of holder basin, is convenient to the user and handles.

The utility model is combined as a whole desk lamp and potted landscape, and is novel, both can throw light on, and can help the user and strike a proper balance between work and rest, do active rest for appreciating again, is particularly suitable for student, intellectual and other personages that need bend over one's desk working for a long time and uses.

Claims (3)

1, a kind of desk lamp is made up of bulb, lamp socket and circuit, it is characterized in that power-supply controller of electric and immersible pump that circuit comprises the master component be made up of light modulation, speed governing electronic device and transformer, is made up of potentiometer, microswitch.

2,, it is characterized in that light modulation, speed governing electronic device mainly comprise bidirectional triode thyristor, overvoltage protection electric capacity and controllable silicon diac, current-limiting resistance according to the described desk lamp of claim 1.
