Abstract

The utility model aims to provide an LED (light emitting diode) lamp with a special cooling structure so as to ensure a good LED particle cooling effect and prolong the service lives of LED particles. The LED lamp comprises a power source, a shell and a lampshade, wherein an LED lamp holder, a cooling body and a reflector are arranged in the shell; a plurality of LED particles are uniformly distributed on the LED lamp holder; the LED lamp holder and the cooling body are in close contact; and the LED lamp holder is arranged between the reflector and the lampshade so that the light emitted by an LED on the LED lamp holder is ejected by the lampshade in the form of single light emitter scattering after being reflected by the reflector. The LED lamp has the light irradiation form of the traditional high-power LED lamps, simultaneously is convenient for cooling, ensures the LED particles inside the LED lamp to have longer service lives, has a simple structure, is convenient to process and maintain, emits light uniformly, avoids ghosting, can be used for lighting of highways, squares, plants, warehouses, dwellings and the like, and has good practicability.

Description

A kind of LED light fixture

Technical field

The utility model belongs to technical field of lamps, specially refers to a kind of LED light fixture.

Background technology

LED illumination had had significant progress in recent years as following green light source, and the LED light fixture has the following advantages: a, power consumption are low: the energy consumption of white light LEDs is merely 1/10 of incandescent lamp, 1/4 of electricity-saving lamp; B, long service life: under appropriate electric current and voltage, can reach 100,000 hours the service life of LED; C, environmental protection: LED is processed by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and LED also can recycling simultaneously.But the LED particle of LED light fixture is after temperature surpasses 66 ℃, and its life-span can sharply descend.To this problem, a lot of high-power LED lamps have all designed radiator structure, but radiating effect is not good enough; This is that all adopt is powerful individual particle LED because present high-power LED lamp is in order to form single light emitting source, and volume is very little; Heat is concentrated; So be difficult to heat radiation, this just causes present high-power LED lamp not possess practicality, is difficult to obtain user's approval.

The utility model content

The purpose of the utility model is to propose a kind of LED light fixture with special radiator structure, and is good to guarantee the heat radiation of LED particle, prolongs its service life.

The LED light fixture of the utility model comprises power supply, housing and lampshade; Key is to be provided with in the said housing LED lamp socket, radiator and refractive body; Said LED lamp socket is evenly distributed with the plurality of LEDs particle, and the LED lamp socket closely contacts with radiator, and said LED lamp socket is between refractive body and lampshade; So that the LED issued light on the LED lamp socket is through after the refractive body reflection, penetrate via lampshade with the form of single light emitting source scattering.

Above-mentioned LED light fixture has been abandoned the way of the single great power LED particle of Traditional use as light emitting source; But adopted many low-power LED particles as light emitting source, and utilize refractive body that the light that many low-power LED particles are sent is reflected, the form that forms single light emitting source scattering penetrates via lampshade; The light of its ejaculation is similar to traditional high-power LED lamp; But because light emitting source is to adopt many low-power LED particles, so its heat distribution relatively disperses, and distributes via radiator easily; Thereby can control the temperature of LED particle better, prolong its service life.

Good for guaranteeing heat radiation, said radiator has at least a part to be exposed to outside the housing.

Specifically, said refractive body has bowl-shape reflecting surface, and said LED lamp socket is installed on the interior week of radiator, evenly is equipped with in the interior week of said LED lamp socket a plurality ofly towards the LED of virtual luminous point particle, and said virtual luminous point is positioned on the refractive body axis.Virtual luminous point on the light directive refractive body axis that the LED particle is sent; Like this through adjusting the angle of refractive body reflecting surface; Can light be reflected away through lampshade; And the reverse extending line of pairing incident ray of reflection ray or reflection ray all passes through virtual luminous point, therefore in LED light fixture outside, just is equal to the form of single light emitting source (virtual luminous point) scattering.

Further, be filled with heat-conducting glue between said radiator and the LED lamp socket,, improve radiating effect to form the radiator structure of tight one.

Further, said radiator and LED lamp socket can be for square or special-shaped, but preferably are circulus, and be so not only easy to process, elegant in appearance, the more important thing is that the reverberation that the LED light fixture emitted is more even.

Further, the periphery of said radiator is provided with the fin that is exposed to outside, to help the heat radiation of LED lamp socket.

The LED light fixture of the utility model has the irradiate light form of traditional high-power LED lamp; Simultaneously convenient again heat radiation guarantees that its inner LED particle has long service life, and is simple in structure, be convenient to processing and maintenance; Luminous even; No ghost phenomena can be used for illuminations such as highway, square, factory, warehouse, local-style dwelling houses, possesses good practicability.

Description of drawings

Fig. 1 is the structure principle chart of the LED light fixture of the utility model.

The specific embodiment

Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.

Embodiment 1:

As shown in Figure 1 (for setting forth principle better; Power supply and housing do not draw among the figure); The LED light fixture of present embodiment comprises power supply, housing and lampshade 1, is provided with LED lamp socket 2, radiator 3 and refractive body 4 in the housing, and LED lamp socket 2 is evenly distributed with many low-power LED particles 5; LED lamp socket 2 closely contacts with radiator 3; LED lamp socket 2 between refractive body 4 and lampshade 1 so that LED particle 5 issued lights on the LED lamp socket 2 through refractive body 4 reflection after, penetrate via lampshade 1 with the form of single light emitting source scattering.

Be filled with heat-conducting glue between radiator 3 and the LED lamp socket 2, form the radiator structure of tight one, the periphery of radiator 3 is provided with the fin 6 that is exposed to outside; Refractive body 4 has bowl-shape reflecting surface 7, and LED lamp socket 2 is installed on the interior week of radiator 3, evenly is equipped with in the interior week of LED lamp socket 2 a plurality ofly towards the LED of virtual luminous point particle 5, and virtual luminous point is positioned on the axis 8 of refractive body 4.

Virtual luminous point on the light directive refractive body axis that LED particle 5 is sent; Like this through adjusting the angle of refractive body reflecting surface 7; Can light be reflected away through lampshade 1; And the reverse extending line of pairing incident ray of reflection ray or reflection ray all passes through virtual luminous point, therefore in LED light fixture outside, just is equal to the form of single light emitting source (virtual luminous point) scattering.
