Description

A kind of LED light fixture that effectively utilizes its thermal source

Technical field

The utility model relates to a kind of LED light fixture, a kind of LED light fixture that effectively utilizes its thermal source of saying so more specifically.

Background technology

At present, domestic LED production industry is flourish, and the brightness of its LED product is increasingly high; Power is less; Eliminated original incandescent lighting product gradually, but some high-power LED light fixture products in actual use, understand because of switching on for a long time producing great amount of heat like its inner substrate of words of long-term unlatching; As do not take cooling measure can cause substrate Yin Wendu too high and be damaged; Therefore in the LED production process, can be equipped with special radiator and help the substrate heat radiation, and the needed radiator of high-power LED light fixture is also big more more, has increased the production cost of LED light fixture like this it; And the luminous heat exhaustion that produces of LED is slatterned in air, do not meet China the energy-saving and emission-reduction aim of extensively praising highly.

The utility model content

The purpose of the utility model is to solve above-mentioned deficiency, provides a kind of simple in structure, and can effectively utilize the LED light fixture of its thermal source.

For solving above-mentioned technical problem, the utility model adopts following technical scheme:

A kind of LED light fixture that effectively utilizes its thermal source that the utility model provided; Comprise lamp housing and substrate, the substrate top is equipped with the LED luminescent device, in the described lamp housing cavity is set; Substrate is fixed on the inwall of lamp housing; And with respect to the substrate top LED luminescent device place is installed on the lamp housing and has at least part to be transparence, and also be provided with an opening on the lamp housing, opening is connected with its internal cavities; Electrode on the substrate is drawn by a side of lamp housing through lead.

Technical scheme further is: described lamp housing is divided into internal layer with outer, and is set to vacuum between internal layer and the skin.

Technical scheme further is: the opening part that is provided with on the described lamp housing also is equipped with blocking device.

Technical scheme further is: the opening on the described lamp housing is arranged on its top.

Technical scheme further is: described lamp housing integral body all is transparence.

Technical scheme further is: described lamp housing is a glass lamp housing.

Compared with prior art, the beneficial effect of the utility model is: through at lamp housing set inside cavity, the radiator heat-dissipation mode that the LED light fixture is traditional changes water-cooling into; Radiator need be installed in addition on the LED light fixture; Practiced thrift its production cost, the water that is used to dispel the heat in the lamp housing cavity in addition can receive the influence heating gradually of substrate heat, can hot water be emitted to do him through the opening at its top and use; In cavity, adding cold water after the use again gets final product; The Btu utilization that substrate is produced in the time of can the LED light fixture being used like this, the call of response China energy-saving and emission-reduction, and a kind of LED fitting structure of its thermal source that effectively utilizes that the utility model provided is simple; Be suitable for suitability for industrialized production, be easy to promote.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

A kind of LED light fixture that effectively utilizes its thermal source as shown in Figure 1, that the utility model provided comprises that lamp housing 5 and its top are equipped with the substrate 1 of LED luminescent device; In the described lamp housing 5 cavity 2 is set; Substrate 1 is fixed on the inwall of lamp housing 5, and has at least part to be transparence with respect to mounted LEDs luminescent device place, substrate 1 top on the lamp housing 5, here for guaranteeing the aesthetic property of LED light fixture; Also can lamp housing 5 integral body all be set to transparence; Lamp housing 5 can adopt any transparent material to be processed into, and for increasing the light transmittance of lamp housing 5 to greatest extent, adopts glass that it is processed in this embodiment; And also be provided with an opening 3 on the lamp housing 5; Opening 3 is connected with its internal cavities 2; Blocking device 6 also is installed on the opening 3; Can make internal cavities 2 and outside isolated fully like this, guarantee to break off that back cavity internal cause LED light fixture work receives the substrate heat effects and the water that heats up still keeps temperature, and then the opening on the lamp housing 53 is arranged on its top at power supply; Electrode on the substrate 1 is drawn by a side of lamp housing 5 through lead 4, is the heat insulation effect that further guarantees lamp housing 5 internal cavities 2 here, preferentially lamp housing 5 is set to internal layer 51 and skin 52, and is set to vacuum between internal layer 51 and outer 52.

The utility model provided a kind of LED light fixture that effectively utilizes its thermal source adds an amount of cold water in actual use in the internal cavities 2 of lamp housing 5, the heat that when the LED lamp luminescence throws light on, is produced is absorbed by the water in lamp housing 5 internal cavities 2; Thereby substrate 1 is played thermolysis; And the water in the internal cavities 2 is heated and heats up, and when the LED light fixture is closed, between lamp housing 5 internal layers 51 and outer 52, makes the water that is heated in its internal cavities 2 keep temperature under the effect of vacuum; When the user need use hot water; The blocking device of opening in lamp housing 5 open tops 36 can be emitted hot water to make his usefulness, outwell the water that is heated in the internal cavities 2 after, add cold water through opening 3 again; Can when use next time of LED light fixture, continue to play radiating effect, circulate with this; When the hot water that need not use in the internal cavities 2, then open the blocking device 6 on the opening 3, can be when reducing substrate 1 temperature, the water in the internal cavities 2 outwards discharges heat through opening 3.
