Abstract

The utility model discloses an LED orientated spotlight, which comprises a lamp holder, a lampshade, a reflecting lamp cup mounted in the lamp holder, a drive circuit board and a plurality of LED light sources mounted in the reflecting lamp cup. The LED orientated spotlight is characterized in that a plurality of slots for mounting the LED light sources in array are arranged on the surface of the reflecting lamp cup; and arc light condensing surfaces are arranged on the side walls of the slots. The LED orientated spotlight is simple in structure, high in lighting efficiency, and environment-friendly, saves energy, and has good promotional value.

Description

The directed Focusing projective light of a kind of LED
Technical field
The utility model relates to lighting technical field, especially relates to a kind of LED shot-light.
Background technology
The tradition shot-light mainly is comprised of lampshade, alternating current ballast and glass lamp, and is filled with thin argon and micro-mercury vapour in the glass lamp, scribbles phosphor powder on the tube wall.Shortcoming is exactly: fluorescent tube burns out blackout easily, and fluorescent tube is frangible explosive, and the aging volatilization of filament is fast, and luminous efficiency is low, and the life-span is short, needs often to change, and service life is on average at 2000-5000 hour.Traditional energy-saving lamp (fluorescent lamp) principle of luminosity excites mercury silver powder by electric field, produces the bavin ultraviolet ray, causes light source.The power saving fluorescent lamps pipe contains mercury and fluorescent tube all is to adopt frangible glass as shell, in case glass breaking, mercury wherein will will be evaporated in the air at once, and moment can make the mercury concentration in the surrounding air reach 10-20 milligram/cubic meter, surpasses the 1000-2000 of national regulation doubly.And mercury is a kind of noxious material extremely harmful to human body, and mercury vapour reaches 0.04 to 3 milligram hour can make people's slow poisoning within 2 to March, reaches 1.2 to 8.5 milligram hours and can bring out acute mercury poisoning, if its amount reaches 20 milligrams, can directly cause animal dead.Fluorescent tube 220V exchanges input, output, in case electric leakage occurs, can touch the body of hurting sb.'s feelings, and caloric value is large, and light decline is short, and anti-weather conditions are poor, and electric leakage, the situations such as short circuit appear in misty rain weather easily.(annotate: use tengsten lamp as Down lamp comprising tradition, and thisly be than the electricity-saving lamp main distinction: tengsten lamp transmits light source by the electricity heating, during use power consumption especially big, so eliminate gradually with market).Majority replaces with surface mounting high-power shot-light (Down lamp) in the market.Also be at present popular popular use product, product is energy-conservation, environmental protection.The LED shot-light is by aluminium base at present, surface mounting high-power lamp pearl, power supply, aluminum alloy casing form, its shortcoming be exactly the general principle of luminosity of LED be by outward scattering of illumination behind the electricity, the LED lamp pearl quantity that the LED shot-light uses is more, the light that LED lamp pearl sends causes overlapping each other easily, not only wastes energy, and can be dazzling especially in the overlapping place of light, and the nonoverlapping place of light will seem secretly, affects light efficiency.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple in structure, simple in structure, and light is even, long service life, and the directed Focusing projective light of energy-efficient LED.
The utility model is to adopt following technical solution to realize above-mentioned purpose: the directed Focusing projective light of a kind of LED, comprise lamp socket, lampshade, be loaded on the reflection Lamp cup in the lamp socket, be loaded on drive circuit board and a plurality of led light source in the reflection Lamp cup, it is characterized in that, described reflection Lamp cup surface is provided with the slotted eye of a plurality of installation led light sources of lining up array, and the sidewall of slotted eye is provided with the arc caustic surface.
Described arc caustic surface is to the crooked curve slope that extends of its centerline direction.
Described curve slope is provided with the cellular reflecting surface that a plurality of hexagon reflective surfaces form.
The angle of inclination of described curve slope is 30-45 °, and the central angle that curve slope is corresponding is 90 ~ 150 °.
Described slotted eye is cellular.
Described led light source adopts directed optically focused LED.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model is optimized improvement design to LED reflectoscope cup-shaped, allows LED light fixture light extraction efficiency promote, and reaches the energy-efficient purpose of LED light fixture.
2, every LEDs light source of the present utility model is installed in the corresponding slotted eye with the arc caustic surface, and on the directed poly-face cellular reflective surface is set also, the light that LED lamp pearl can be sent converges, therefore, can not superpose between the light that each led light source sends, brightness is consistent, and light is even.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is LED mounting structure schematic diagram of the present utility model;
Fig. 3 is arc caustic surface structural representation of the present utility model.
Description of reference numerals: 1, lamp socket 2, lampshade 3, reflection Lamp cup 4, led light source 5, slotted eye 6, arc caustic surface 7, cellular reflecting surface.
The specific embodiment
As shown in Figure 1-Figure 3, the directed Focusing projective light of a kind of LED of the utility model comprises lamp socket 1, lampshade 2, is loaded on the reflection Lamp cup 3 in the lamp socket 1, is loaded on drive circuit board and a plurality of led light source 4 in the reflection Lamp cup 3, and led light source 4 generally adopts directed optically focused LED.Reflection Lamp cup 3 surfaces are provided with the slotted eye 5 of a plurality of installation led light sources of lining up array, and it is cellular that slotted eye is, and the sidewall of slotted eye is provided with arc caustic surface 6.Wherein, arc caustic surface 6 is to the crooked curve slope that extends of its centerline direction.Curve slope is provided with the cellular reflecting surface 7 that a plurality of hexagon reflective surfaces form, and the angle of inclination of curve slope is 30-45 °, and the central angle that curve slope is corresponding is 90 ~ 150 °.
Above-described only is preferred embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
