1, the housing framework of existing LED Projecting Lamp is to adopt plastics or sheet iron to make substantially, service life is shorter, and be much higher than the service life of LED, promptly lamp casing framework and light emitting source life-span do not match, and cause comparative lifetime reduction, the relative cost of light fixture to increase; in life-span of lamp casing framework
2, the faying face of the lamp ring of light fixture and housing, power line are introduced the housing place in the lamp and are adopted General Purpose Rubber to level up face to compress and seal, and sealing effectiveness is relatively poor;
3, because the housing framework of light fixture is not the coupling setting with new light emitting source one large-power light-emitting diodes, then the radiating effect of light fixture is bad;
4, the housing framework of existing LED Projecting Lamp adopts plastics or sheet iron to make, and housing framework intensity is not high, is subjected to certain bump or the long period illumination is used, and is easy to make the electrical connection of light fixture to go wrong and causes potential safety hazard.
The utility model content
One of the purpose of this utility model is will solve existing LED Projecting Lamp housing framework and the light emitting source life-span does not match, the not high technical problem of housing framework intensity;
Another purpose of the present utility model is to solve the existing technical problem that LED Projecting Lamp sealing effectiveness is relatively poor, radiating effect is bad, proposes a kind of comparative lifetime height, good seal, good, the safe LED Projecting Lamp of heat radiation.
For addressing the above problem, the technical scheme that the utility model proposes is to adopt the high-strength material of perfect heat-dissipating to make lamp ring and housing, its structure comprise the lamp ring, Transparent Parts, speculum, LED cohort, the circuit board that is electrically connected with this LED cohort and the control circuit board that are linked in sequence, housing, introducing power supply cable, wherein: be provided with the flute profile sealing gasket between the faying face of described lamp ring and described Transparent Parts, the edge of described Transparent Parts embeds in the groove of described flute profile sealing gasket; Be concavo-convex the cooperation between described lamp ring and the described casing joint surface, be provided with compressible seal in the groove of described lamp ring faying face; Described housing is introduced the clamp nut that described cable place is provided with the compressible seal circle and compresses the sealing circle.
Wherein: described lamp ring and housing can be made by alloy aluminum.
Described circuit board is installed on the erection column that is extended out by described shell inner surface; Described control circuit board is installed on the support column that is extended out by described shell inner surface, described control circuit board and the described circuit board certain interval of being separated by.
Described LED cohort is the LED of same color or different color combination.
The circuit of described control circuit board can make described LED cohort send the combined light of the light of same color or different color or long bright or produce different frequently any of dodging.
The utility model adopts the high strength housing framework of perfect heat-dissipating, makes lamp casing framework and light emitting source life-span be complementary, improved greatly light fixture service life, lowered relative cost, improved the crashworthiness of light fixture simultaneously, removed potential safety hazard; Adopt special sealing gasket, effectively water and dustproof; Circuit board is connected with the housing of perfect heat-dissipating by its erection column with heating components and parts such as control circuit boards, and makes control circuit board and the circuit board certain interval of being separated by, fully guaranteed the heat radiation needs of light fixture; LED cohort and a control circuit board of the combination of same color or different color are set, make the LED cohort can send the combined light of the light of same color or different color or long bright or produce different frequently any of dodging, thereby increased the function of use of light fixture.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done detailed explanation, wherein:
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a cut-away illustration of the present utility model;
Fig. 3 is the stereogram of the utility model speculum;
Fig. 4 is the stereogram of the utility model housing;
Fig. 5 is the schematic diagram of the utility model control circuit.
The specific embodiment
Fig. 1 and Fig. 2 show preferred embodiment of the present utility model, described LED Projecting Lamp, comprise the lamp ring 1, high-intensity Transparent Parts 2, speculum 3, LED cohort 4, the circuit board 5 that is electrically connected with this LED cohort and the control circuit board 6 that are linked in sequence, housing 7, introduce power supply the cable (not shown), described lamp ring 1 and housing 7 adopts perfect heat-dissipatings, aluminium alloy that intensity is high to make, and also can adopt other perfect heat-dissipatings, material that intensity is high to make.Thereby make lamp casing framework and light emitting source life-span be complementary, improve service life, the attenuating relative cost of light fixture, also can improve the crashworthiness of light fixture simultaneously, remove potential safety hazard.
As shown in Figure 4, described circuit board 5 is installed on the erection column 8 that is extended out by described housing 7 inner surfaces; Described control circuit board 6 is installed on the support column 9 that is extended out by described housing 7 inner surfaces, described control circuit board 6 and described circuit board 5 certain interval of being separated by.The heat that electrical part work is sent can be delivered to housing by erection column and support column, and heat is distributed to the external world, has fully guaranteed the heat radiation needs of light fixture.
