Abstract
The utility model relates to a kind of LED down, comprise lamp socket, aluminium base and heat abstractor, the both sides, inside of described lamp socket are provided with fixed head, described fixed head is connected by hold-down screw with between aluminium base, described heat sink interior is provided with heat dissipation cavity, described heat dissipation cavity inside is connected with radiator fan by fixed mount, and described heat abstractor is provided with several louvres.The utility model, by arranging fixed head, hold-down screw, by being connected with fixed head by hold-down screw by aluminium base, can be convenient to the installation and removal of aluminium base so like this; By arranging radiator fan, louvre, like this when light fixture works, aluminium base can produce a large amount of heats, now enter cold wind in the effect of radiator fan from louvre side, heat is discharged from backstop by opposite side, the temperature be convenient to like this on aluminium base gives out outside light fixture in time, and can effectively reduce lamp pearl generation heat affects the temperature of aluminium base, improves the service life of components and parts on aluminium base.
Description
Technical field
The utility model relates to technical field of LED illumination, particularly relates to a kind of LED down.
Background technology
Light emitting diode is referred to as LED.The diode be made up of the compound containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) etc.Can visible ray be given off when electronics and hole-recombination, thus can be used for making light emitting diode.As indicator lamp in circuit and instrument, or form word or numerical monitor.Gallium arsenide diode glows, gallium phosphide diode green light, silicon carbide diode Yellow light-emitting low temperature, gallium nitride diode blue light-emitting.Because chemical property divides again Organic Light Emitting Diode OLED and inorganic light-emitting diode LED.Light emitting diode also can be divided into normal monochrome light emitting diode, high brightness LED, superhigh brightness LED, color-changing light-emitting diode, blinking light emitting diode, voltage-controlled type light emitting diode, infrarede emitting diode and negative resistance light emitting diode etc.The control model of LED has constant current and constant voltage two kinds, has multiple dimming mode, such as simulates light modulation and PWM light modulation, what most LED adopted is current constant control, the stable of LED current can be kept like this, be not subject to the change of VF, the service life of LED lamp can be extended.
Down lamp is that one is embedded in ceiling, the lighting penetrated under light.From price, Down lamp uses electricity-saving lamp more common than LED down as light source, but from light efficiency, the luminous efficiency of LED down will be got well more than traditional energy-conserving barrel lamp.LED down generally comprises lamp cylinder, radiator, LED aluminum base plate, reflector and face ring, the heat that LED lamp bead in existing LED down produces concentrates on aluminium base, easily like this cause the temperature on aluminium base too high, make the components and parts on aluminium base short for service life, thus directly affect the service time of Down lamp, illumination zone is little simultaneously, and existing LED aluminum base plate installs inconvenience.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of LED down.
The utility model is achieved through the following technical solutions:
A kind of LED down, comprise lamp socket, aluminium base and heat abstractor, the both sides, inside of described lamp socket are provided with fixed head, described fixed head is connected by hold-down screw with between aluminium base, described heat sink interior is provided with heat dissipation cavity, described heat dissipation cavity inside is connected with radiator fan by fixed mount, and described heat abstractor is provided with several louvres.
As optimal technical scheme of the present utility model, the exit of described heat abstractor is provided with backstop.
As optimal technical scheme of the present utility model, be formed in one between described fixed head and lamp socket.
As optimal technical scheme of the present utility model, described louvre is low inside and high outside skewed layout.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging fixed head, hold-down screw, by being connected with fixed head by hold-down screw by aluminium base, the installation and removal of aluminium base can be convenient to so like this; By arranging radiator fan, louvre, like this when light fixture works, aluminium base can produce a large amount of heats, now enter cold wind in the effect of radiator fan from louvre side, heat is discharged from backstop by opposite side, the temperature be convenient to like this on aluminium base gives out outside light fixture in time, and can effectively reduce lamp pearl generation heat affects the temperature of aluminium base, improves the service life of components and parts on aluminium base.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. lamp socket; 2. aluminium base; 3. fixed head; 4. hold-down screw; 5. heat abstractor; 6. heat dissipation cavity; 7. backstop; 8 fixed mounts; 9. radiator fan; 10. louvre.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of LED down, comprise lamp socket 1, aluminium base 2 and heat abstractor 5, the both sides, inside of described lamp socket 1 are provided with fixed head 3, are formed in one between wherein said fixed head 3 and lamp socket 1.
Described fixed head 3 is connected by hold-down screw 4 with between aluminium base 2, by being connected with fixed head 3 by hold-down screw 4 by aluminium base 2, can be convenient to the installation and removal of aluminium base 2 so like this.Described heat abstractor 5 inside is provided with heat dissipation cavity 6, and the exit of wherein said heat abstractor 5 is provided with backstop 7.
Described heat dissipation cavity 6 inside is connected with radiator fan 9 by fixed mount 8, and described heat abstractor 5 is provided with several louvres 10, and described louvre 10 is in low inside and high outside skewed layout, and such louvre 10 arrangement can effectively reduce dust and enter.Like this when light fixture works, aluminium base 2 can produce a large amount of heats, now enter cold wind in the effect of radiator fan 9 from louvre 10 side, heat is discharged from backstop 7 by opposite side, the temperature be convenient to like this on aluminium base 2 gives out outside light fixture in time, lamp pearl generation heat can be effectively reduced affect the temperature of aluminium base 2, improve the service life of components and parts on aluminium base 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
