Abstract
The utility model discloses a low-temperature high lighting efficiency LED daylight lamp. The low-temperature high lighting efficiency LED daylight lamp comprises LED chips, at least one transparent ceramic substrate, a transparent ceramic lampshade and at least one plug coated by radiant heat dissipating materials. The LED chips are fixed to the transparent ceramic substrate, the transparent ceramic substrate is clamped on the transparent ceramic lampshade, a plurality of heat dissipating holes are formed in the plug coated by the radiant heat dissipating materials, and the transparent ceramic lampshade is fixed to the plug coated by the radiant heat dissipating materials. Compared with an existing LED lamp of the same specification, the lighting efficiency of the low-temperature high lighting efficiency LED daylight lamp is increased by about 50%, under the same lighting efficiency, the power is lower, and temperature rise can be controlled within 40 DEG C.
Description
Technical field
The utility model relates to the LED field of illuminating lamps, refers to especially a kind of low
TemperatureThe LED fluorescent lamp of high light efficiency.
Background technology
The radiating mode of present existing LED fluorescent lamp tool is generally that the LED chip heat is transmitted on the aluminium section pedestal by substrate, profile base is directly by dissipation of heat on the one hand, heat is by being transmitted on fluorescent light plug on the other hand, then distributed by the hole of fluorescent light plug.Because the aluminium section pedestal can stop and absorb light, cause the light fixture light efficiency low.And general plug basically can not rate of heat dissipation, is unfavorable for reducing lamp temperatures.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of LED fluorescent lamp that possesses high heat radiation is provided.
The utility model is achieved through the following technical solutions:
The LED fluorescent lamp of the high light efficiency low temperature of the utility model, comprise LED chip, at least one crystalline ceramics substrate, crystalline ceramics lampshade, at least one scribbles the plug of heat loss through radiation material; Described LED chip is fixed on the crystalline ceramics substrate; Described crystalline ceramics substrate card is on the crystalline ceramics lampshade; On the described plug that scribbles the heat loss through radiation material, open some louvres; Described crystalline ceramics lampshade is fixed on the plug that scribbles the heat loss through radiation material.
The heat that the utility model uses the crystalline ceramics lampshade to reduce fluorescent-lamp tube is put aside, and by the crystalline ceramics substrate directly is stuck on the crystalline ceramics lampshade, the heat that LED chip produces can be directly transferred on the crystalline ceramics lampshade.The crystalline ceramics lampshade possesses high heat-sinking capability on the one hand, can conduct heat on the plug that scribbles the heat loss through radiation material on the other hand, then by the heat loss through radiation material quick heat radiating on plug.Simultaneously, on fluorescent light plug, have louvre, to form hot-air convection, improve the effect heat radiation.Through experiment showed, that the utility model compares the existing LED light fixture of same equal-specification, light efficiency improves approximately 50%.The power that reaches equal light efficiency is lower, and temperature rise can be controlled in 40 degree.
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described further.
The accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Fig. 3 is cross-sectional structure schematic diagram of the present utility model.
Fig. 4 is another kind of structural representation of the present utility model.
Fig. 5 is another kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model comprises LED chip 1, six crystalline ceramics substrates 2, one-body molded crystalline ceramics lampshade 3, a plug 4 that scribbles the belt electrode 6 of heat loss through radiation material; Described LED chip 1 is bonded on crystalline ceramics substrate 2 by high heat conduction elargol (not shown); The both sides of described crystalline ceramics substrate 2 are stuck on crystalline ceramics lampshade 3; On the described plug 4 that scribbles the heat loss through radiation material, open some louvres 5; One of described crystalline ceramics lampshade 3 is fixed on the plug 4 that scribbles the heat loss through radiation material.
During fluorescent lamp work of the present utility model, the heat that one side LED chip 1 produces is transmitted on crystalline ceramics lampshade 3 by crystalline ceramics substrate 2, part heat directly exhales by crystalline ceramics lampshade 3, another part heat is transmitted on plug 4, then by the heat loss through radiation material on plug 4, heat radiation is exhaled.The heat that produces of LED chip 1, by the absorption of air in fluorescent tube, then conducts through louvre 5 convection current on plug 4 on the other hand.Crystalline ceramics substrate 2 and crystalline ceramics lampshade 3 can not block and absorb the light that LED chip 1 sends in addition, and the light fixture light efficiency is high.
As shown in Figure 4, the utility model comprises that LED chip 1, six crystalline ceramics substrates 2, integrated crystalline ceramics lampshade 3, lamp body two ends are respectively arranged with the plug 4 and the not electroded plug 4 that scribbles the heat loss through radiation material that scribble the belt electrode 6 of heat loss through radiation material; Described LED chip 1 is bonded on crystalline ceramics substrate 2 by high heat conduction elargol (not shown); The both sides of described crystalline ceramics substrate 2 are stuck on crystalline ceramics lampshade 3; On the described plug 4 that scribbles the heat loss through radiation material, open some louvres 5; Two of described crystalline ceramics lampshade 3 is connected with the plug 4 at lamp body two ends respectively.
As shown in Figure 5, the utility model comprises that LED chip 1, six crystalline ceramics substrates 2, integrated crystalline ceramics lampshade 3, lamp body two ends respectively are provided with a plug 4 that scribbles the belt electrode 6 of heat loss through radiation material; Described LED chip 1 is bonded on crystalline ceramics substrate 2 by high heat conduction elargol (not shown); The both sides of described crystalline ceramics substrate 2 are stuck on crystalline ceramics lampshade 3; On the described plug 4 that scribbles the heat loss through radiation material, open some louvres 5; Two of described crystalline ceramics lampshade 3 is connected with the plug 4 at lamp body two ends respectively.
