Description
Technical field
The utility model belongs to lighting field, is specially a kind of LED spot light.
Background technology
At present, along with the raising of people's living standard, the construction in city also further improves; Many cities are decorative beautifying environment, enrich people's spare-time cultural life, on the lawn of park plaza, often be equipped with in place such as fountain, river course wants the decoration light that cooperates with the pond.The outdoor spot light of existing LED is made up of cover cap, LED circuit for lamp plate and bottom, wherein LED lamp and lead directly weld, or the LED lamp is welded on the LED circuit for lamp plate by connecting line and forms, because the naked weldering of LED lamp, cause LED to be subjected to static or high temperature to cause internal injury easily, and shock resistance is not good enough.Therefore both easily solder joint get loose, light source internal injury together easily again, thus make the spotlight source device lost of life.This LED circuit for lamp plate includes a plurality of LED illuminators simultaneously, has the effect of light source irradiation, because the light direct projection, emergent ray is comparatively dazzling.Simultaneously, the outdoor use of being everlasting of this lamp for preventing that into water damages LED circuit for lamp plate, is sewed on usually and is stamped fluid sealant and prevent to leak being connected between cover cap and bottom, if improper but play glue, then occurs the situation of leaking easily, and it is unreliable to use.
Because the restriction of this body structure of LED spot light, its water resistance is relatively poor, can only be applicable on the road surface to use, and can not use under water; But because the power of LED spot light is bigger, and the sealing of whole lamp body, exist heat dispersion bad, temperature is too high in the lamp body will cause LED to damage and influence the problems such as life-span of lamp; Also do not address the above problem better technical scheme at present.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of improvement of LED spot light is provided, and this LED spot light should have good looking appearance, water resistance is good, luminous efficiency is high, illumination range is big, mixed light is effective and the service-strong characteristics.
The technical solution adopted in the utility model is: a kind of LED spot light, comprise lampshade, lamp housing and be arranged on the base plate of lamp housing bottom, be provided with the LED power panel in the described lamp housing, it is characterized in that: described LED power panel is provided with several equally distributed LED particle and constant-current driven chips, also is filled with one deck heat-conducting glue between described LED particle and the constant-current driven chip.By the constant-current driven chip that welding on the LED power panel is electrically connected with the LED particle, the current constant of the feasible LED particle of flowing through is constant, has not only increased the stability of LED particle, but also has improved the service life of LED particle.By fill the heat-conducting glue bonding between LED particle and constant-current driven chip, the heat that the LED particle produces conducts to lamp housing by LED power panel, heat-conducting glue successively, dispels the heat better heat-radiation effect by whole light fixture.
As preferably, the upper surface of described lamp housing edge is provided with groove, and described LED power panel is by being bolted on the groove, and the outer wall of described groove is provided with screw thread, and is threaded with screw capping on the annular that the lampshade bottom is provided with.The annular screw capping of going up is set plays fixedly connected, waterproof action.
As preferably, also be provided with the multilayer flashing rubber ring between the last screw capping of described groove and annular.The purpose that the water proof rubber circle is set is better sealing, and anti-sealing infiltrates in the light fixture from the slit.
As preferably, evenly be shaped on one group of concave shaped heat radiation ring recess that is parallel to each other on the outer wall of described lamp housing.Concave shaped heat radiation ring recess can increase area of dissipation, improves the thermal diffusivity of light fixture integral body, thereby prolongs the service life of light fixture.
As preferably, also be provided with power line incoming line and power line line outlet on the described lamp housing.The inner ring of power line incoming line and power line line outlet is provided with and the close-fitting waterproof washer of lead, and the purpose that waterproof washer is set is better sealing, and anti-sealing infiltrates in the light fixture from power line incoming line and power line line outlet; Have the high characteristics of classification of waterproof, be specially adapted to underwater lighting.
As preferably, respectively be provided with one around the described base plate leg is installed.
As preferably, be bolted to connection one on the described installation leg sucker is installed.By sucker is installed, it is easy for installation that whole spot light is had in use, the readily removable advantage of removing.
As preferably, be bolted to connection a screw on the described installation leg.
As preferably, described lampshade, lamp housing are circle or similar round structure, and described lampshade is made of the optical grade LGP.It is inhomogeneous to have solved the ubiquitous mixed light of existing LED lamp, glare problem, and its light emission rate height, lighting angle is greater than 150 degree, and range of exposures is big, and light emission rate reaches more than 93%, and the common LED lamp can only reach 75%.
The beneficial effects of the utility model are: good looking appearance, classification of waterproof height are not only applicable to outdoor road surface irradiation to IP68, can also be used under water.Long service life, the LED lamp of identical light efficiency is economized power consumption 80%, using electricity wisely cost greatly than incandescent lamp; On service life, LED can reach more than 30,000 hours, was tens times of service life of incandescent lamp, thereby used the LED lamp not only to reduce the replacement cost of light source, can also reduce maintenance cost.Since adopted the optical grade light-passing board as lampshade have the luminous efficiency height, illumination range is big, mixed light is effective and the service-strong characteristics.Also evenly be shaped on one group of concave shaped heat radiation ring recess that is parallel to each other on the outer wall of lamp housing, increase area of dissipation, improve the thermal diffusivity of light fixture integral body, thereby prolong the service life of light fixture.
