Abstract
The utility model discloses an LED fluorescent lamp with an external power supply, comprising an LED fluorescent lamp body; the LED fluorescent lamp body is connected with the external power supply, the external power supply comprises a PCB circuit board, an input terminal, an output terminal and a power supply case, the PCB circuit board is arranged in the power supply case, the input terminal is connected with the LED fluorescent lamp body by the PCB circuit board and the output terminal. The LED fluorescent lamp in the utility model eliminates the adverse effect of the heat radiation of the power supply which works on the LED light source performance, and a ballast and a starter are not needed in the working process, thereby effectively saving the energy consumption of the ballast; an LED fluorescent lamp tube and the external power supply part can be conveniently arranged in a bracket of the traditional fluorescent lamp without arranging accessories additionally. Compared with the prior art, the LED fluorescent lamp has convenient installation and maintenance, and the overhauling of the external power supply can not affect the LED fluorescent lamp body, therefore, the LED fluorescent lamp has high power factor.
Description
Technical field:
The utility model relates to a kind of LED lighting device, particularly a kind of LED fluorescent lamp of external power supply.
Background technology:
At present, the LED fluorescent lamp generally adopts the mode of built-in power, is about to power circuit and partly is installed to LED fluorescent tube inside, and what it can be successful is converted into direct current supply with alternating current, supplies with led light source and makes it luminous.But the LED fluorescent lamp of built-in power is unfavorable for the heat dissipation design of LED fluorescent lamp owing to this meeting distribute heat when working of power supply, influences the performance of light source.Therefore the situation that causes the LED fluorescent lamp to be scrapped owing to power failure can appear in the LED fluorescent lamp of built-in power, even built-in power is overhauled, will dismantle LED fluorescent tube body yet, safeguard very inconvenience, the power factor of the LED fluorescent lamp of built-in power is generally not high yet in addition.
Summary of the invention:
For addressing the above problem, the purpose of this utility model is to provide a kind of LED fluorescent lamp of external power supply.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of LED fluorescent lamp of external power supply, comprise LED daylight lamp body, be connected with an external power supply on this LED daylight lamp body, described external power supply comprises PCB circuit board, input and output terminal, power pack, the PCB circuit board is built in the power pack, and input terminal is connected with LED daylight lamp body by PCB circuit board, lead-out terminal.
The utility model separates the power-supply system of LED fluorescent lamp with lamp tube body, eliminated the adverse effect that the led light source performance is caused owing to dispel the heat during power supply work itself, and it is convenient for installation and maintenance, external power supply can be installed in the traditional fluorescent lamp support, and the LED fluorescent tube can directly be installed on the traditional fluorescent lamp support; The LED fluorescent lamp of external power supply need not ballast and starter when working, and has saved because the energy consumption that ballast itself produces.Maintenance to external power supply can not have influence on LED fluorescent tube body, and the LED fluorescent lamp of external power supply has very high power factor in addition, can reach more than 90%.
LED fluorescent lamp external power supply partly comprises the PCB circuit board, and its two ends are connected to the input and output terminal respectively, and circuit board is installed in the power pack and fixes.The size of power supply satisfies the support that can be fit into traditional fluorescent lamp just.During installation, at first ballast in the traditional fluorescent lamp support and starter are removed, then original input in the support, output line are connected with input, the output of power supply.If energising back finds have red light bright in the fluorescent tube, then expression input, output termination are anti-, only need turn wiring position and get final product.After determining that installation is errorless, energising can be lighted the LED fluorescent tube.
The adverse effect that heat radiation when the utility model has been eliminated owing to power supply work itself causes the led light source performance; Need not ballast and starter in the work, saved effectively because the energy consumption that ballast itself produces; LED fluorescent tube and external power supply part thereof can be installed in the support of traditional fluorescent lamp easily, need not other installation accessories.Compared with prior art, the utlity model has convenient for installation and maintenancely, can not have influence on LED fluorescent tube body to the maintenance of external power supply, and the utlity model has very high power factor, its value reaches more than 90%.

The specific embodiment:
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also Fig. 1, shown in Figure 2, the utility model provides a kind of LED fluorescent lamp of external power supply, mainly include LED daylight lamp body, be connected with an external power supply on this LED daylight lamp body, described external power supply comprises PCB circuit board, input terminal 2 and lead-out terminal 3, power pack 1, the PCB circuit board is built in the power pack 1, and input terminal 2 is connected with LED daylight lamp body by PCB circuit board, lead-out terminal 3.
The input terminal 2 of LED fluorescent lamp is connected with outside civil power or alternating current, and 3 of lead-out terminals directly are connected with the LED fluorescent tube, 85～265V alternating current can be converted into the 70V direct current and supply with the LED fluorescent tube by this LED external power supply.
The utility model LED fluorescent tube can directly be installed on the traditional fluorescent lamp support; External power supply then can be installed in the support of traditional fluorescent lamp by reasonably repacking wiring, when LED fluorescent lamp of the present utility model is worked, need not ballast and starter.
More than the LED fluorescent lamp of a kind of external power supply provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
