Description
Technical field
The utility model relates to the LED lighting, and it is good particularly to relate to a kind of heat dispersion that adopts the high heat conductive insulating plastics to make, safe LED light fixture.
Background technology
LED had obtained swift and violent development in recent years as a kind of emerging light source, and various LED application products have all embodied the incomparable advantage of conventional lamp, and had tentatively obtained the approval in market.But in the existing LED light fixture product commonly used,, substantially all adopted the metal material of high thermal conductivity to do the Lamp cup shell, and utilized the Lamp cup shell to dispel the heat in order to solve the very crucial heat dissipation problem of LED.But do shell with metal,, just have a series of major defect: be exactly related constraint and the restriction between heat radiation, safety, appearance and size for the little high-tension product of those volumes.
As everyone knows, as the electricity consumption product, its security is most important assurance, has just clearly stipulated the safety requirements of electronic product and light fixture product as IEC61010-1 and IEC60598-1.Much be originally the product of glass or plastic casing, design with metal now, the general requirement is used as power drives with isolated power supply, adopt the structure of the LED light fixture of isolated power supply generally to be divided into three parts: front end is lens, be used to assemble the light of LED outgoing, mid portion is a metalized lamp cup, is used for the installation and the heat radiation of led light source chip, tail end is the insulator of a hollow, in order to hold driving power.But adopt isolated power supply certainly will will increase the volume of whole light fixture, finally can cause small product size bigger than conventional lamp on the contrary, will limit even violate relevant IEC rules like this to the applied environment of product to some extent, just the product size of part light source be had strict requirement such as IEC60061-1.
Have is exactly to use non-isolated power drives again, power circuit and metalized lamp cup are fully insulated, because the thickness of insulating layer of LED substrate itself has only about 50 μ m, so will add a layer insulating in addition between LED substrate and the metalized lamp cup, in order to LED substrate and metalized lamp cup is isolated fully, the conduction of most important one deck heat just was greatly affected during LED used like this, though there is metal shell to dispel the heat, but the conduction of the heat of the inside is obstructed, and whole cooling system is also undesirable.And can bring potential safety hazard, in case there is inner lead to touch lamp housing, consequence is with hardly imaginable.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, provide a kind of thermal conductivity good, volume is little, good insulating, safe LED light fixture Lamp cup and use the LED light fixture of this Lamp cup, Lamp cup adopts the high heat conductive insulating plastics to make, so heat conductivility and security all improve a lot than before, and volume also reduces than before, in the led light source container cavity in this external Lamp cup metal heat-conducting spare is set, passing on heat radiation Lamp cup outer surface and the fin that the heat that can make led light source distribute is the fastest conducted, convection current and heat loss through radiation have fully solved the heat dissipation problem of led light source.
The technical solution of the utility model is achieved in that a kind of LED light fixture Lamp cup, this Lamp cup includes radiating element, in radiating element, be provided with led light source container cavity and drive circuit board container cavity, be provided with a plurality of fin on the outer surface of radiating element, radiating element and fin are by the compression molding of high heat conductive insulating plastics one.
As preferably, described led light source container cavity and drive circuit board container cavity are to be separated by the division board that is provided with on the axial direction, and division board and radiating element are the one compression molding.

As preferably, the lower end of described thermal conductive surface offsets with division board and contacts.So that location.
As preferably, described a plurality of fin are on the vertical or horizontal outer surface that is disposed on radiating element.
As preferably, to the other end, the width of fin increases gradually along the exit direction of light by an end of radiating element.Because the heat around the light-emitting window is more concentrated, greater than width, be beneficial to heat radiation away from the fin at light-emitting window place near the width of the fin at light-emitting window place.
As preferably, be provided with a guard circle at an end of the light-emitting window of radiating element along the outer ledge of fin, leave the space between guard circle and the radiating element.Guard circle can prevent that the edge of fin from scratching staff, and can protect fin to have prevented foreign object it to be collided; Leave the slit between guard circle and the radiating element, can make that the inside and outside air in interval between two fin forms convection current, be beneficial to heat radiation.
As preferably, the thickness of described fin is 0.5mm～10mm.Because fin is that high heat-conducting plastic is made, so the I of thickness reaches 0.5mm, to save material and more to help heat radiation.
As preferably, the lower end of described heat-conducting plate offsets with insulation board and contacts.
A kind of LED light fixture, this LED light fixture comprises that as preceding each described Lamp cup be provided with the led light source that is installed on the substrate in the led light source container cavity, substrate closely is fixed on the stationary plane, be provided with drive circuit board in the drive circuit board container cavity, led light source is electrically connected with drive circuit board.
As preferably, between substrate and stationary plane, scribble heat-conducting glue, substrate is fixed on the stationary plane by screw.
Adopted the advantage that the utlity model has of technique scheme to be:
One, Lamp cup adopts the high heat conductive insulating plastics to make, so thermal conductivity is good, good insulating, safe, needn't use isolated power drives, so that volume also can be done is littler;
Two, pre-buried or embedded metal heat-conducting spare in the led light source container cavity of Lamp cup, the stationary plane of metal heat-conducting spare is in order to fixed L ED light source installation base plate, the thermal conductive surface of metal heat-conducting spare closely pastes mutually with the Lamp cup inner surface, because the heat conductivility of metal is better, dispel the heat so can make heat that led light source produces be sent on the outer surface of Lamp cup and the fin with prestissimo.
