Abstract
The utility model provides an LED light bar. The LED light bar comprises a flexible circuit board and a plurality of LED lamps installed on the flexible circuit board which is in a bar shape, and the surface of the flexible circuit board is covered by copper. The flexible circuit board is provided with a positive electrode connecting end and a negative electrode connecting end both of which are arranged at the same end of the flexible circuit board. According to the LED light bar, the flexible circuit board is covered by the copper in a large-scale mode, and therefore the loss of voltage on the flexible circuit board is reduced. The positive electrode connecting end and the negative electrode connecting end are arranged at the same end of the flexible circuit board, and meanwhile to ensure that all LED lamps can reliably work, external voltage passes through a voltage-stabilized source management chip after entering the LED light bar, and then the external voltage is connected to an LED drive chip and the LED lamps, so that integral LED luminance is even. The purposes of supplying electricity at one single end and not affecting the luminance are achieved. The LED light bar can be connected with an external controller, so that a user sets the using effect of the LED light bar, and requirements under different conditions are met.
Description
Technical field
The utility model relates to a kind of LED lamp bar.
Background technology
In order to satisfy the atmosphere in red-letter day, the Christmas tree of small household and a year tangerine also begin to dress up with LED now.A string LED of available technology adopting Alternating Current Power Supply decorates, and the effect of this decoration LED light fixture is single, and the effect of variation is fixed, and voltage is ac high-voltage simultaneously, and security is not high.The LED lamp that also has a kind of low-voltage power supply although what adopt is also low pressure, need to once be powered every 20 LED, the power supply that need to access when reality is used so often, troublesome poeration, water proofing property are poor, the security reduction.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of LED lamp bar, comprise flexible PCB, be installed on a plurality of LED lamps of flexible PCB, described flexible PCB is that copper is covered on bar shaped and surface, described flexible PCB is provided with anodal incoming end and negative pole incoming end, and described anodal incoming end and negative pole incoming end are arranged at the same end of described flexible PCB.
Further, described a plurality of LED lamp is connected mutually.
Further, described a plurality of LED lamps are installed on described flexible PCB, and the two adjacent LEDs lamp is crisscross arranged.
Further, described LED lamp bar of the present utility model also is provided with power management chip, LED drives chip, and described power management chip, described LED drive chip and described LED lamp connects successively.
Further, described LED lamp bar also is provided with overload protective device, and overload protective device is arranged between LED lamp and anodal incoming end.
Further, described LED lamp bar also is provided with the lampshade that covers at the LED lamp, described lampshade inboard and the outside are provided with patterned layer, and described described lampshade outer pattern layer and the inboard patterned layer of being arranged at blocked overlapping or interlaced along the light emission direction of the light emitting diode of LED lamp mutually.
Compared to prior art, LED lamp bar of the present utility model carries out large tracts of land to flexible PCB and covers copper, reduces the loss of voltage on flexible PCB.The anodal incoming end of flexible PCB and negative pole incoming end are arranged at the same end of flexible PCB, simultaneously in order to guarantee each LED lamp reliably working, the external voltage rear voltage-stabilized power supply managing chip that first passes through of coming in, then access LED and drive chip and LED lamp, thereby guarantee that whole LED brightness is also uniform.Reached is that single-ended power supply does not affect again the effect of brightness.But external controller, set up on their own the result of use of LED lamp bar by the user simultaneously, satisfies the needs of different situations.
Description of drawings
Fig. 1 is the structural representation of LED lamp bar of the present utility model.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment, the utility model is further illustrated.
See also Fig. 1, the utility model provides a kind of LED lamp bar 10, and the LED lamp 13, power management chip 15, the LED that comprise flexible PCB 11, are installed on flexible PCB 11 drive chip 17.LED lamp bar 10 of the present utility model can be used for the Christmas tree of household small-size and a year tangerine are decorated.
The flexible PCB 11 of LED lamp bar 10 of the present utility model is bar shaped, which is provided with connecting circuit and is connected in anodal incoming end and the negative pole incoming end of connecting circuit.Described anodal incoming end and negative pole incoming end are arranged at the same end of described flexible PCB 11.LED lamp bar 10 of the present utility model is provided with a plurality of LED lamps 13, and a plurality of LED lamps 13 are series at the connecting circuit of flexible PCB 11.Be understandable that, two adjacent LEDs lamp 13 can be crisscross arranged.In the present embodiment, copper is covered on flexible PCB 11 surfaces, thereby helps flexible PCB 11 dispel the heat and reduce voltage loss.LED lamp bar 10 of the present utility model also is provided with power management chip 15, LED drives chip 17.External power source, power management chip 15, LED drive chip 17 and LED lamp 13 connects successively.LED lamp bar 10 of the present utility model also is provided with overload protective device, and overload protective device is arranged between LED lamp 13 and anodal incoming end.Described LED lamp bar 10 also is provided with the lampshade that covers at LED lamp 13, described lampshade inboard and the outside are provided with patterned layer, and described described lampshade outer pattern layer and the inboard patterned layer of being arranged at blocked overlapping or interlaced along the light emission direction of the light emitting diode of LED lamp 13 mutually.
10 pairs of flexible PCBs of LED lamp bar of the present utility model 11 carry out large tracts of land and cover copper, reduce the loss of voltage on flexible PCB 11.The anodal incoming end of flexible PCB 11 and negative pole incoming end are arranged at the same end of flexible PCB 11, simultaneously in order to guarantee each LED lamp 13 reliably working, the external voltage rear voltage-stabilized power supply managing chip 15 that first passes through of coming in, then access LED and drive chip 17 and LED lamp 13, thereby guarantee that whole LED brightness is also uniform.Reached is that single-ended power supply does not affect again the effect of brightness.But external controller, set up on their own the result of use of LED lamp bar 10 by the user simultaneously, satisfies the needs of different situations.
