The specific embodiment

Below in conjunction with Figure of description in detail technical solutions of the utility model are described in detail.

As the solid of Fig. 1 a, Fig. 1 b, look up shown in the assembling schematic diagram of structural representation and Fig. 2, wherein disclose a kind of LED Down lamp with glare prevention structure, comprising can be for the metal shell 6 of heat radiation, and at least one places the light source assembly 4 of the surface mount LED in the aforementioned housing; Be located in the aforementioned housing 6 for one, and aforementioned surfaces can be mounted led light source assembly periphery and cover, and the cellular or star pattern reflector of can glare prevention structure using 3; And one link with aforementioned housing, and be connected with surface mount led light source assembly, and the driving power assembly 9 that can power, lamp socket 8 and bright dipping cloche 2; Down lamp housing 6 is aluminium matter or alloy material; Housing 6 one ends evenly are provided with the bigger radiator of multiple tracks surface area ratio 7, and the buckle 5 that is symmetrically distributed all around has several heat dissipation ventilation holes on the lamp socket 8, and the heat that produces during LED work is by these radiators 7 and air vent dissipation.

The bottom of these housing 6 inner chambers is a planar structure, mounts the light source assembly 4 of great power LED above with heat-conducting glue, and reflector is arranged on the light-emitting window of the light source assembly 4 of LED; The top of lamp socket 8 connects binding post, positioned inside driving power assembly 9, and an end of binding post links to each other with driving power assembly 9.

There is said structure to ensure, monochromatic large-power light-emitting diodes LED both can be installed in Down lamp, the large-power light-emitting diodes LED of All-in-One color also can be installed, by 9 controls of driving power assembly and allotment, form white light or other color light, strengthen light effects greatly.

Shown in Fig. 3 a, Fig. 3 b, Fig. 4 a and Fig. 4 b, this glare prevention structure is a core with the reflector 3 with anti-dazzle and scattering property, and this reflector 3 is that a circle is moulded shell, and wall is coated with one deck plated film layer within it, makes this reflector have splendid light reflectance.Wherein, reflector 3 inside are provided with and the led light source assembly 4 tight supporting cellular stars or the reverberation bowl of rhombus, the reverberation bowl inwall is curved surface or planar structure, the light that the large-power light-emitting diodes led light source sends is by reflector 3 refraction and scatterings, further improve whole brightness, prevent that dazzle from producing.

This bright dipping cloche 2 is made by optical material (for example PMMA, PC, the glass etc.) integral of light transmission high-quality, and the surface is handled through pickling or atomizing or ultrawhite and made, and light is soft after the light source bright dipping, and integral body is compacter, and is more harmonious, more attractive in appearance.

This hull outside has one can be for the cover of dismounting, and cover symmetry semi-circumference place is provided with one respectively can be for the locating slot of location usefulness, reaching firmly, and in that install can be more easy, quick.

This driving power assembly 5 places housing 1 inside, be made of electric main or low-tension supply constant current conversion control circuit assembly or constant-current source assembly, and an end is connected with the aluminium base electrode, and the other end is connected with the lamp socket binding post.Wherein, connect driving power assembly and binding post, can avoid directly contacting, and, the driving power assembly be broken down because of the heat that housing distributed with housing with lamp socket.

The technical program can directly introduce electric main or the low-tension supply constant current is powered to LED, and its circuit theory as shown in Figure 5.Power-supplying circuit constitutes: the anti-jamming circuit that electric main constitutes by typical L1 and C1, form high direct voltage by full wave bridge type D1～D4 rectification and through capacitor C 2 filtering, U1 converts low-voltage dc power supply to through the AC/DC conversion module, capacitor C 3 elimination high frequency clutters, send into the constant-current source circuit formation low pressure constant current of integrated circuit U2 (R1) again, and then be fed to light emitting diode D6 for core.If the use dc source can directly add constant-current source circuit, be fed to light-emitting diode component again.

The utility model provide a kind of use high-power (〉=1W), the light emitting diode of high brightness is as the Down lamp of lighting source, has unique advantage:

(1) compare with lighting sources such as traditional incandescent lamp and Halogen lamp LEDs, what the utility model used is cold Light source, small product size is little, in light weight, caloric value is little, and luminous efficiency is far above incandescent lamp and Halogen lamp LED, its Operating voltage is low, power consumption is few, and energy-saving effect is remarkable.

(2) the utility model is solid-state module, and is simple in structure, annex seldom, shock-resistant, vibration resistance, Safe and reliable, can save raw material, reduce product cost, by in housing outer surface heat radiation being set Device efficiently solves the LED heat dissipation problem, so can save cost and improve service life.

(3) reflector of the cellular star in the utility model Down lamp or rhombus can be with the point of LED lamp Shaped laser spot zooms into scattered light, makes the illumination in the effective lighting scope more even, can play the anti-dazzle effect And dispersion effect, can allow again the LED Luminaire efficiency greatly improve.

(4) can directly introduce electric main or the low-tension supply constant current is powered to LED, luminous steadily, No stroboscopic does not contain near infrared ray and ultraviolet ray.

In one word: because lamp socket, radiator, shell combination install, and because of the stretching of radiator itself Structure can increasing heat radiation area, so after adjusting light source power, radiating effect can not reduce, and can save Cost-saving, and weight is lighter does not just need too greatly so time space is installed, and more can conveniently install, and is widely used in The concentration of local illumination of public place such as market, arts center, recreational facilities etc. and family.
