Description
Technical field
The utility model relates to a kind of high-power LED surface light source Down lamp, belongs to technical field of lamps.
Background technology
Light emitting diode because of have energy-saving and environmental protection, safety, the life-span is long, adjustable, colour rendering index is high, light is soft, no stroboscopic and plurality of advantages such as radiationless, has obtained increasingly extensive application.At present, LED illuminating product major part is to adopt low power LED or paster LED to make, but because its required LED quantity is more, and illumination is not enough, so do not reach the requirement of general illumination.Along with the lifting of large-power light-emitting diodes luminous efficiency, adopt high-power LED lamp to replace traditional lighting to become reality.Yet existing high-power LED lamp though illumination can reach the requirement of general illumination, is a spot light because it adopts, so there is problem such as lack of homogeneity.
The utility model content
The purpose of this utility model is to provide that a kind of emission angle is wide, good uniformity and photochromic soft adjustable high-power LED surface light source Down lamp.
Its technical scheme is: a kind of high-power LED surface light source Down lamp, and comprise cylindrical shell, go up dish and led circuit plate, it is characterized in that: the described dish of going up is the housing of hollow out, pastes one deck reflective membrane on its inwall; Be fixed with drive circuit on the described led circuit plate and evenly be fixed with some great power LEDs, this led circuit plate is fixed on last dish inner chamber by screw and is connected on the connector that is provided with; Be provided with diffuser plate lid between the bottom of last dish and the body end surface, by screw by on try to get to the heart of a matter screw that end face outwards offers on the edge of turnover insert the screw of outwards offering on the edge of turnover with the cylindrical shell upper surface and be connected and fixed.Its technique effect is: because great power LED is evenly distributed on the circuit board, each LED can both be penetrated from the angle of the best, form area source, thereby effectively solved the shortcoming that the existing high-power LED lamp of traditional low-power LED ray cast angle finite sum adopts spot light; Simultaneously, last dish adopts the housing form of hollow out, satisfied the radiating requirements of great power LED, on last dish inwall, paste reflective membrane, the luminous flux of great power LED is reflected to greatest extent, improve the illumination of Down lamp, adopt the diffuser plate lid of high transmission rate, make great power LED luminous evenly, light is soft.Therefore, Down lamp of the present utility model has that emission angle is wide, a good uniformity, photochromic soft adjustable etc. characteristics, is applicable to room lighting, particularly the illumination of ceiling ceiling light; And Down lamp is made easy to assembly, and cost price is low.
Description of drawings
Fig. 1 is an assembling schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the high-power LED surface light source Down lamp comprises cylindrical shell, goes up dish and led circuit plate.Described upward dish 8 is the housing of hollow out, pastes one deck reflective membrane (not shown) on its inwall.Described led circuit plate 7 adopts aluminium base circuit board, is the flat circle shape.Be fixed with drive circuit 6 on it and evenly be fixed with some great power LEDs, this led circuit plate is fixed on last dish inner chamber by screw 5 and is connected on the connector that is provided with.Be provided with the diffuser plate lid 3 of high transmission rate between the end face of the bottom of last dish and cylindrical shell 2, by screw 9 by on try to get to the heart of a matter screw that end outwards offers on the edge of turnover insert the screw of outwards offering on the edge of turnover with cylindrical shell 1 upper surface and be connected and fixed.Between the great power LED of evenly fixing on the above-mentioned led circuit plate 7, adopt the connected mode of serial or parallel connection.
Above-mentioned great power LED can adopt the light emitting diode of random color and the encapsulation of form arbitrarily.
Be pasted with light-transmissive film 4 on the above-mentioned diffuser plate lid 3.
Above-mentioned cylindrical shell 1 both sides are respectively equipped with the shell fragment of being convenient to install 2.
