Description
(1), affiliated technical field
The utility model relates to a kind of lampion, and particularly a kind of LED that is used for decorating under water is lamp under water.
(2), technical background
Existing LED lamp under water generally is to include diffuser, gland, lamp body, the electronic devices and components that the LED light emitting diode are housed and match on the circuit board that is provided with in the lamp body.The present formation LED gland and the used material of lamp body of lamp under water has two kinds, and a kind of employing ABS engineering plastics are made, and another kind adopts metal such as materials such as copper, stainless steel to make.The LED Under water lamp that adopts the ABS engineering plastics to make has reliable, advantage such as cost is lower, handling ease, intensity height, good toughness and antiseptic property are strong handsome in appearance, easy to connect, but exist a deadly defect that influences the LED operate as normal, that is exactly that the heat-conductive characteristic of ABS engineering plastics is very poor.As everyone knows, during LED energising work, its electronic devices and components can produce heat inevitably, and as underwater light source, lamp body must make the inner electrical equipment and the external world separate fully, heat in the lamp body can only outwards pass by the diffuser made from thicker glass, though the heat-conductive characteristic of diffuser is better than engineering plastics, but can not satisfy the requirement of the abundant heat radiation of very big LED semiconductor light emitting chip of lamp body internal density and support circuit fully, therefore, at present for fear of LED under water the heat of lamp working time long-term accumulation cause owing to the too high LED of damage luminescence chip of temperature and associated electrical components and parts, have to reduce the quantity of LED, lamp power is less than normal under water thereby cause, the result that brightness is on the low side, this is restricting the promotion and application of led light source fully.The lamp under water that adopts stainless steel to make though have the strong advantage of intensity height, toughness and thermal conductivity, exists antiseptic property poor, processing and manufacturing cost height, and lamp body moulding dullness is stiff, conducts electricity deficiencies such as functional reliability difference under water easily.
(3), summary of the invention
The purpose of this utility model just provides a kind of with low cost, aesthetic in appearance and LED heat dissipation type engineering plastics that light projector is effective lamp under water, its heat in the lamp body that leaves effectively, avoid LED semiconductor light emitting core light and associated electrical components and parts Yin Gaowen and damage the service life of prolongation product.
The purpose of this utility model is to realize by such technical scheme, it includes diffuser and the gland made from engineering plastics, lamp body, the electronic devices and components that the LED light emitting diode are housed and match on the circuit board that is provided with in the lamp body, it is characterized in that: the port that is interlinked to the outside in lamp body is provided with is provided with the heat-transfer metal sheet that seals port in the lamp body.The heat-transfer metal sheet can adopt the fabulous aluminum material of heat transfer efficiency to make, and also can make with copper or stainless steel material.When LED luminescence chip energising work; it passes to the heat-transfer metal sheet with the air that the heat that relevant supporting component is produced can be led in the lamp body in the mode of convection current; the heat-transfer metal sheet transmits heat rapidly to the boundary in the mode of conduction; thereby the heat that is produced in the lamp body that in time leaves; avoid LED luminescence chip and relevant supporting component Yin Gaowen and damage; the functional reliability of the electronic component in the protection lamp body has prolonged service life of the present utility model.
Owing to adopted technique scheme, the utlity model has simple in structure, with low cost, aesthetic in appearance, light projector is effective and practical advantage such as reliable, its heat in the lamp body that leaves effectively, avoid LED semiconductor light emitting core light and associated electrical components and parts Yin Gaowen and damage the service life of prolongation product.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. diffuser; 2. gland; 3.LED light emitting diode; 4. electronic devices and components; 5. circuit board; 6. fluid sealant; 7. lamp body; 8. compacting ring; 9. heat-transfer metal sheet; 10. insulating heat-conductive glue or insulating heat-conductive fat; 11. port.
(5), the specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes diffuser 1 and the gland made from engineering plastics 2, lamp body 7, the electronic devices and components 4 that LED light emitting diode 3 are housed and match on the circuit board 5 that is provided with in the lamp body 7, it is characterized in that: the port 11 that is interlinked to the outside in lamp body 7 is provided with is provided with the heat-transfer metal sheet 9 that seals port 11 in the lamp body 7.Heat-transfer metal sheet 9 can adopt the fabulous aluminum material of heat transfer efficiency to make, and also can make with copper or stainless steel material.When LED luminescence chip energising work; it passes to heat-transfer metal sheet 9 with the air that the heat that relevant supporting component 4 is produced can be led in the lamp body in the mode of convection current; heat-transfer metal sheet 9 transmits heat rapidly to the boundary in the mode of conduction; thereby the heat that is produced in the lamp body that in time leaves; avoid LED luminescence chip and relevant supporting component Yin Gaowen and damage; the functional reliability of the electronic component in the protection lamp body has prolonged service life of the present utility model.
As shown in Figure 1, heat-transfer metal sheet 9 can be sealed on the port 11 by compacting ring 8, fluid sealant 6.
As shown in Figure 1, in order to strengthen the performance of outside heat conduction in the lamp body, in the lamp body 7, between circuit board 5 and heat-transfer metal sheet 9, be provided with insulating heat-conductive glue or insulating heat-conductive fat 10.Heat in the lamp body can pass to heat-transfer metal sheet 9 in the mode of conducting by insulating heat-conductive glue or insulating heat-conductive fat 10, to strengthen the performance that heat is transmitted.
