Abstract
The invention discloses an LED ceiling lamp with adjustable brightness and color temperature. The LED ceiling lamp comprises a lampshade, wherein a group of true yellow light beads and a group of true white light beads are mounted in the lampshade, each group of beads are connected with corresponding control circuit respectively and comprise 45 LED beads, the 45 LED beads comprise 3 parallelly connected bead rows, each bead row comprises 15 beads connected in series, the maximum output current of each group of beads is 450 mA, and the voltage is 45 V-50 V. The LED ceiling lamp with adjustable brightness and color temperature has the advantages as follows: the brightness and color temperature can be adjusted automatically according to change of the external environment, or various profiles are defined by a user, so that appropriate brightness and color temperature can be selected by one key, for example, the highest brightness and daylight color temperature can be provided for a reading mode, the brightness and color temperature can be reduced to those of a night light for a sleep mode and the lamp can be automatically turned off in a time delayed manner, and the like.
Description
Technical field
The present invention 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 object of this invention is to provide a kind of LED lamp affixed to the ceiling of brightness-adjustable adjustable color temperature, concrete scheme of the present invention 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.
Advantage of the present invention: 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 invention;
Fig. 2 is controller architecture figure of the present invention.
detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
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.
