Description

A kind of LED Projecting Lamp

Affiliated technical field

The utility model relates to illumination, LED (light emitting diode) light source and technical field of lamps.

Background technology

Projecting Lamp in the market divides two big classes: be traditional Projecting Lamp of light source with the gas-discharge lamp and be the novel Projecting Lamp of light source with LED.From development trend, traditional Projecting Lamp is because of bulky and waste energy and withdraw from the market at leisure, and what replace is the LED Projecting Lamp.Now the LED Projecting Lamp on the market has does not have drive circuit, causes lamp life to reduce greatly.Have drive circuit is arranged but the inner lead that is used for light source does not adopt printed circuit and interconnects with independent lead, seem very disorderly, be easy to occur wrong, short circuit and breaking phenomena.From the thermal design aspect, present many LED Projecting Lamps think little of the heat dissipation problem of wick, thereby cause the life-span to be reduced greatly.Aspect design of light source overall appearance and mounting means, the single and very difficult adjustment lamp holder of traditional Projecting Lamp installation position, the lighting requirement of special occasions is difficult to satisfy.Aspect the lamp luminescence angle, traditional Projecting Lamp is finalized the design fully, and angle can not be adjusted flexibly according to user's requirement.

Summary of the invention

It is the light fixture of the novel concept of light source with LED that the purpose of this utility model provides a kind of, efficient height not only, and also whole light fitting shape is elegant in appearance.In the mentality of designing that has broken through traditional Projecting Lamp aspect structure, heat radiation, light design and the mounting means fully, overcome the weak point of existing LED Projecting Lamp, energy-conservation, environmental protection is easy to install, and is convenient to adjust.

The specific embodiment

The utility model is made up of two big parts: lamp head shell assembly and base assembly.Wherein the lamp head shell assembly is made up of panel, face glass, sealing ring, cover plate, positioning stud, lens, LED wick, aluminium base, lamp head shell, water joint etc.; Base assembly is made up of water joint, terminal box, brace, friction plate, pressing plate, square neck bolt, base, power supply lead wire, nameplate and various connectors etc.Two big parts link together by six screws (13).

Advantage of the present utility model is mainly reflected in following three aspects:

The light design aspect: light source adopts the 1wLED wick, it is revolutionary light source of the 4th generation, light efficiency reaches more than the 80Lm/W, all led light sources on the market before being higher than 2009, and along with development of technology, light efficiency is also improving constantly, and estimates will reach 110Lm/W in 2010, and energy-saving effect is fairly obvious; Whole lamp source by 28 independently LED form, each LED joins independently lens, it is adjustable from 10 ° to 60 ° that light passes luminous angle behind the lens, even can do more, and do not disturb mutually between the lens, in particular cases can be each independently LED manufacture the lens of predetermined angular; Aspect colour temperature and color, but all independent design and replacings of each LED; A plurality of LED more can be by the control of program, conversion goes out different flicker effect, thereby build the illumination atmosphere of different angles, different photochromic, different-colour and different flicker effect to greatest extent, to satisfy market for the increasing specific demand of product.In addition, lamp holder of the present utility model can be mounted to two kinds of different states, promptly horizontal dress state and perpendicular dress state, and very big flexibility, this point are provided also is that in the market Projecting Lamp is not available for product is used for this.

Thermal design aspect: in lamp holder inside, the utility model has adopted the good aluminium base of heat conductivility, aluminium base is screwed on the inner surface of lamp head shell, and is firm for guaranteeing that aluminium base contacts with the lamp head shell inner surface, is coated with heat-conducting silicone grease at the interlayer of these two faces.Can derive fast for the assurance heat, whole shell of lamp base has adopted aluminium, and has arranged a plurality of heat radiation ribs at the back side of lamp head shell, thereby has increased the area of dissipation of housing greatly, and this is very important to the life-span that prolongs LED.

The circuit design aspect: the utility model has abandoned thoroughly that common drive circuit separates with the Lights section circuit on the market, and the method for designing that back panel wiring is very disorderly adopts incorporate printed circuit design scheme, and the reliability that has improved circuit is beneficial to installation again.Another characteristics are: drive circuit, control circuit are placed in the space of circuit of light sources, reduced the quantity of circuit, saved many spaces.

Structural design aspect: divide two major parts, lamp head shell assembly and base assembly.Can connect into two kinds of different states by screw (13), promptly horizontal dress state and perpendicular dress state between this two big part.Under two states, lamp holder all can rotate a certain angle around fixing rotating shaft, this on the one hand can adjust angle flexibly according to on-the-spot installation situation, on the other hand fully can with lamp installation and non-level surface, thereby provide very big flexibility for application.

Lamp head shell main body profile is oval, and material is a die casting aluminium, bossed heat radiation rib in housing back and the screwed hole that is used to be connected base, and steel water joint (8) is equipped with at the center.Bottom (inner surface) is smooth smooth, and there is internal electric source lead-in wire entrance hole at the center; LED wick and circuit are housed on the aluminium base, are connected in the shell of lamp base bottom surface by dog screw (21); Lens card guarantees the accurate of location in the centre of LED lamp and cover plate (20) according to the corresponding aperture on dog screw and the cover plate; Between enclosure interior and outside, there are face glass (23) and circular washer (25) to add the fastening effect of screwing and guarantee necessary sealing.Circular washer adopts circular foamed silastic to surround, and temperature resistant range is-100 °～250 °, guarantees that light fixture can adapt to the test of outdoor low temperature and high temperature; The transmission element of light fixture---face glass (23) is made greater than 90% safety glass by light transmittance.Screw application of force inequality may cause the cracking fragmentation of safety glass when preventing installation panel (1), has filled up a plain washer (24) between panel (1) and face glass (23).

For guaranteeing enough strength and stiffness, base assembly all adopts steel, and the top column has partly adopted " worker " font structure, guarantees that lamp body has certain anti-destruction and non-deformability.Column uses the riveting of steel rivet on base substrate.Square terminal box (9) is installed on the substrate, and sealing and fixing is installed with bridge rectifier in the terminal box, and the terminal box lateral surface has two steel water joints, and a joint connects the internal electric source lead-in wire, and another connects the external power source lead-in wire.In the middle square protrusion of base assembly, the product nameplate is installed.

Aspect the fixed-site of lamp holder, adopted than the more reliable method of general Projecting Lamp, promptly strengthen moment of friction, thereby can guarantee under the effect of littler screw threads for fastening power, can make lamp holder to be in a certain position that regulates by the method that increases friction plate (14) and pressing plate (15).Brace (12), friction plate (14), base assembly and pressing plate (15) link together by square neck bolt (17) and nut (16).
