Abstract
The utility model discloses a kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature, comprise lampshade, lampshade inside is equiped with one group of positive yellow fluorescent lamp pearl and one group of positive white light pearl, often organize lamp pearl to be connected with corresponding control circuit respectively, often organize lamp pearl by 15 strings 3 and 45 LED lamp pearls form, the output current often organizing lamp pearl is maximum 450mA, and voltage is 45V-50V.The utility model advantage: can change according to external environment, automatic adjustment brightness and colour temperature, or by the various contextual model of User Defined, one key selects applicable brightness and colour temperature, as reading model can provide high-high brightness and color of sunshine colour temperature, sleep pattern then can drop to the brightness of mini light night and colour temperature and automatic time delay is turned off the light etc.
Description
Technical field
The utility model relates to a kind of LED lamp affixed to the ceiling.
Background technology
Lamp affixed to the ceiling is household bedroom, light fixture is commonly used in parlor, study, existing light fixture color is single, and brightness constancy, along with growth in the living standard, people wish that light fixture can have the change of more multicolour and brightness, more energy-conservation and have certain intelligent function, can improve life staying idle at home temperament and interest.Thus, a kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature is needed.
Summary of the invention
The present utility model object is to provide a kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature, and concrete scheme of the present utility model is:
A kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature, comprise lampshade, lampshade inside is equiped with one group of positive yellow fluorescent lamp pearl and one group of positive white light pearl, often organize lamp pearl to be connected with corresponding control circuit respectively, often organize lamp pearl by 15 strings 3 and 45 LED lamp pearls form, single lamp pearl voltage is 3.0-3.3V, and the output current often organizing lamp pearl is maximum 450mA, and voltage is 45V-50V.
Described control circuit comprises wireless/infrared control circuit, pulsewidth modulation Programmable Logic Controller circuit and constant-current drive circuit; Described pulsewidth modulation Programmable Logic Controller circuit controls its pulsewidth by light-inductive control circuit and timing circuit; Described constant-current drive circuit provides dc source by current rectifying and wave filtering circuit.
The utility model advantage: can change according to external environment, automatic adjustment brightness and colour temperature, or by the various contextual model of User Defined, one key selects applicable brightness and colour temperature, as reading model can provide high-high brightness and color of sunshine colour temperature, sleep pattern then can drop to the brightness of mini light night and colour temperature and automatic time delay is turned off the light etc.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model;
Fig. 2 is controller architecture figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature, comprise lampshade 1, lampshade 1 inside is equiped with one group of positive yellow fluorescent lamp pearl 2 and one group of positive white light pearl 3, often organize lamp pearl to be connected with corresponding control circuit 4,5 respectively, often organize lamp pearl by 15 strings 3 and 45 LED lamp pearls form, single lamp pearl voltage is 3.0-3.3V, and the output current often organizing lamp pearl is maximum 450mA, and voltage is 45V-50V.
Described control circuit comprises wireless/infrared control circuit, pulsewidth modulation Programmable Logic Controller circuit and constant-current drive circuit; Described pulsewidth modulation Programmable Logic Controller circuit controls its pulsewidth by light-inductive control circuit and timing circuit; Described constant-current drive circuit provides dc source by current rectifying and wave filtering circuit.
Timing circuit and light-inductive circuit are used at " automatically " MODE of operation, it is 6 .-18 periods of morning when the time, pulsewidth modulation programmable circuit provides signal, control constant current output circuit 2, for the work of LED white light group, the power that brightness then experiences ambient light according to light-inductive circuit adjusts automatically, to reach best observable index; When the time is 6 pm, pulsewidth modulation programmable circuit then controls constant current output circuit work, and for the work of LED gold-tinted group, the power that brightness then experiences ambient light according to light-inductive circuit adjusts automatically, to reach best observable index; Timing circuit can also be turned on light by the self-defined timing of client or be turned off the light.Utilize wireless/infrared controller to set multiplex mode, under sleep pattern, automatically proceed to mini light night after 10 minutes, colour temperature is gold-tinted, and brightness is 5% of overall power; Under reading model, colour temperature is white light, and brightness is 100% of overall power; Horizontal pattern, white light gold-tinted mixed luminescence in proportion; Also by the adjustment brightness of wireless/infrared controller " manually " button and colour temperature, brightness is adjustable between general power 5%-100%, and colour temperature is adjustable between 2700K ~ 6400K.
Below disclose the present invention with preferred embodiment, so it is not intended to limiting the invention, and all technical schemes taking the form of equivalent replacement or equivalent transformation to obtain, all drop within protection scope of the present invention.
