Abstract
The utility model relates to a LED tool comprising a LED illuminant and a seat electrically connected to the external environment. The utility model is characterized in that the seat is provided with a hollow shell, the surface of the shell is provided with two or more groups of parallel connected LED lamp clusters electrically connected with the seat; at least two series connected LED illuminants are arranged inside the LED lamp cluster; the shell is provided with a heat radiation hole; a current-limiting resistance electrically connected with the LED lam cluster is arranged inside the shell; and a control circuit module electrically connected with the seat and the LED lamp cluster are respectively arranged inside the shell. The LED lamp of the utility model has simple structure and long service life.
Description
Technical field
The utility model relates to a kind of lighting apparatus, is a kind of LED light fixture specifically.
Background technology
Traditional lighting generally adopts incandescent lamp bulb or fluorescent tube.Because the power that incandescent lamp bulb and fluorescent tube use is all bigger, and service life is generally not long, so it is replaced by the LED light emitting diode of low price, long service life gradually.Yet because single LED illuminator luminance shortage, light fixture just can play illuminating effect under the simultaneously luminous situation of a plurality of LED illuminators.But existing LED light fixture generally all is to increase the luminous efficiency of LED illuminator by adding high-amperage, its structure is a plurality of LED illuminators of welding on the pcb board of control circuit, this LED light fixture is except the structure more complicated, its magnitude of current is also bigger, caloric value is also bigger, has shortened the service life of LED light fixture greatly.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the LED light fixture of long service life.
Goal of the invention of the present utility model is achieved in that a kind of LED light fixture, comprise LED illuminator and the base that is electrically connected with the external world, it is characterized in that: described base is provided with hollow housing, surface of shell is provided with the LED lamp group that at least two groups are connected in parallel and are electrically connected with base, is provided with at least two LED coupled in series illuminators in the LED lamp group.
Have louvre on the described housing.
Be provided with the current-limiting resistance that is electrically connected with LED lamp group in the described housing.
Be provided with the control circuit module that is electrically connected with base and LED lamp group respectively in the described housing.
The utility model improves existing LED light fixture, is provided with series connection and the LED lamp group that is connected of mixing in parallel on a hollow housing surface.Because the LED illuminator is to use series connection and in parallel the mixing, therefore the stability of its electric current is stronger than simple in parallel or series connection in use, makes the longer service life of LED illuminator.Have louvre on the housing, effectively LED light fixture heat is discharged.Be provided with the current-limiting resistance that is electrically connected with LED lamp group in the housing, make the magnitude of current of LED lamp group be reduced to rated value.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
According to shown in Figure 1, LED light fixture of the present utility model comprises LED illuminator 1 and base 2, and base 2 is electrically connected with extraneous.Base 2 is provided with hollow housing 3, and at least two group LED lamp groups are installed on the surface of this housing 3.For being connected in parallel, and be electrically connected between the LED lamp group with base 2.Then be provided with at least two LED illuminators 1 in the LED lamp group, between the LED illuminator 1 for being connected in series.The heat that produces for LED illuminator 1 work the time is discharged housing 3, and the electronic component in the protection housing 3 also has louvre 4 on housing 3.In addition, also be provided with the current-limiting resistance that is electrically connected with LED lamp group in the housing 3, this current-limiting resistance can reduce the electric current of the LED illuminator 1 of flowing through the rated value of LED illuminator 1, effectively reduces the live load of LED illuminator 1, prolongs its service life.Simultaneously, this LED light fixture can also be provided with the control circuit module, and the control circuit module is installed in the housing 3, is electrically connected with base 2 and LED lamp group respectively.The control circuit module except can to the LED illuminator 1 in the LED lamp group bright, put out and control, strengthen outside the sight of LED light fixture, can also carry out rectification to the electric current that enters base 2, very convenient to use.
