Description

A kind of LED sterilizing lamp set

Technical field

The utility model relates to a kind of LED sterilizing lamp sets.

Background technique

The conversion ratio that the electricity of existing LED bactericidal lamp turns light is usually 30%-50%, and deep ultraviolet LED current electricity turns light Conversion ratio also can only be to 10% hereinafter, major part energy can be converted into thermal energy when LED bactericidal lamp works, for the LED of small volume Bactericidal lamp radiates more difficult.Air-cooled technology is mostly used to radiate LED bactericidal lamp greatly in the prior art, by cooling fin It is tightly bonded with LED sterilization lamp substrate (being provided with circuit on substrate), then is gone to dispel backing with fan, so that heat be taken away. But it is still limited using the heat-sinking capability of air-cooled technical approach, as the power demand of LED bactericidal lamp is increasing, volume Demand is smaller and smaller, and traditional radiating mode is not able to satisfy industrial requirement gradually.

Utility model content

The utility model greatly improves dissipating for itself to solve the above problems, provide a kind of LED sterilizing lamp set The thermal efficiency is particularly suitable for high-power LED bactericidal lamp.

To achieve the above object, the technical solution adopted in the utility model are as follows: a kind of LED sterilizing lamp set, including LED are killed The chip of bacterium lamp and the circuit being electrically connected with the chip further include TEC refrigerator, the TEC refrigerator have cold end face and Hot end face, the circuit are directly laid on the cold end face of the TEC refrigerator, and the chip is welded on the circuit.

Optionally, copper mode or plating mode or chemistry are directly covered by printing-sintering mode or DBC on the cold end face Plating mode is laid with the circuit.

Optionally, the material in the cold end face includes aluminium oxide, aluminium nitride, beryllium oxide, silicon nitride or enhanced oxidation aluminium Ceramics.

Optionally, the conversion ratio that the electricity of the chip turns light is less than or equal to 30%.

Optionally, the radiant power of the chip is more than or equal to 20 mw.

Optionally, the radiant power of the chip is 50-200mw.

The beneficial effects of the utility model are: the utility model by LED sterilizing lamp set be arranged TEC refrigerator, The circuit of LED bactericidal lamp being directly laid on the cold end face of TEC refrigerator, the chip of LED bactericidal lamp is welded on circuit, this Sample carries out active heat removal to chip by TEC refrigerator, also, since circuit is the cold end face of TEC refrigerator of being directly laid in On, intermediate thermal conductivity part is thus eliminated, therefore radiating efficiency can be greatlyd improve, efficiency is high, is particularly suitable for big function The LED bactericidal lamp of rate.

Detailed description of the invention

Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model Improper restriction.In the accompanying drawings:

Fig. 1 is the structural schematic diagram according to a kind of LED sterilizing lamp set of an embodiment of the present invention.

Specific embodiment

In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein Example is applied only to explain the utility model, is not used to limit the utility model.

As shown in Figure 1, a kind of LED sterilizing lamp set of an embodiment of the present invention, the chip including LED bactericidal lamp 10, circuit 20, the TEC refrigerator 30 being electrically connected with chip 10.

TEC refrigerator 30 has cold end face 31 and hot end face 32, when the anode 33 and cathode 34 of TEC refrigerator 30 are passed through directly When galvanic electricity stream or addition voltage, cold end face 31 is absorbed heat, and 32 heat release of hot end face, the working principle of TEC refrigerator 30 is known skill Art is not described in detail here.

Circuit 20 is directly laid on the cold end face 31 of TEC refrigerator 30, that is to say, that circuit 20 is directly formed at On the cold end face 31 of TEC refrigerator 30, without intermediate thermal conductivity part etc. between circuit 20 and cold end face 31.Chip 10 is welded in circuit 20 On.Active heat removal is carried out to chip 10 by TEC refrigerator 30 in this way, also, since circuit 20 is the TEC refrigeration that is directly laid in On the cold end face 31 of device 30, intermediate thermal conductivity part is thus eliminated, therefore radiating efficiency can be greatlyd improve, efficiency is high.

The mode that circuit 20 is directly laid on the cold end face 31 of TEC refrigerator 30 can there are many selections, such as can be with Copper mode or plating mode or chemical plating mode etc. are directly covered using existing printing-sintering mode or DBC, these existing electricity Road system of laying is able to achieve on the cold end face 31 for TEC refrigerator 30 that circuit 20 is directly laid in.

The material in cold end face 31 may include aluminium oxide, aluminium nitride, beryllium oxide, silicon nitride or enhanced oxidation aluminium ceramics Deng.

The conversion ratio that the electricity that the LED sterilizing lamp set of the utility model is particularly suitable for chip 10 turns light is less than or equal to 30%, The radiant power of chip 10 is more than or equal to the case where 20 mw, further, even if the radiant power of chip 10 is 50-200mw model In enclosing, TEC refrigerator 30 can also play good heat dissipation effect, extend LED sterilizing lamp set shelf life.

The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then It all should be in the protection scope of the appended claims for the utility model.
