Description
Technical field
The utility model relates to light fixture preparing technical field, relates in particular to a kind of LED lamp.
Background technology
The low-power LED lamp of wide-angle luminescence in the market, all adopts the structural manufacturing process of similar LEDbulb lamp.In this light fixture, the contact surface of aluminium base and radiator is very little, and the heat produced when causing LED chip to work cannot pass on radiator, reduces the service life of light fixture.In addition, its light source substrate processing technology just uses separating aluminium substrate, is divided into 6-8 sheet, after the independent SMT paster of every sheet aluminium base, more shaping with manual welding, processing technology is complicated, needs very skilled workman just can complete.Therefore suitable labor intensive cost, and cause production fraction defective to remain high.
Utility model content
For solving the problem, the utility model provides a kind of LED lamp.
Concrete technical scheme of the present utility model is as follows:
A kind of LED lamp, comprise lamp socket, LED drives, light source substrate, pressure-casting type heat radiating cup and heat-dissipation aluminum sectional material, described pressure-casting type heat radiating cup upper end connects heat-dissipation aluminum sectional material, lower end connects lamp socket, described light source substrate comprises cross aluminium base and LED paster, described LED paster is mounted on cross aluminium base surface, four extension of described cross aluminium base are bent, be nested in the upper surface of described aluminum profile heat radiator after four extension bending formings of described cross aluminium base and be fixed as one with aluminum profile heat radiator, described LED drive installation is inside lamp socket, and be connected on light source substrate through casting formula heat radiating cup and heat-dissipation aluminum sectional material.
By adopting this scheme: light source substrate is integrated, significantly simplifying the work flow of light source substrate thus, decreasing cost of labor prepared by this LED lamp, reduce production fraction defective.The heat that LED paster sends reaches heat-dissipation aluminum sectional material through cross aluminium base, then reaches pressure-casting type heat radiating cup by heat-dissipation aluminum sectional material and be finally dispersed in air.The contact surface of cross aluminium base and heat-dissipation aluminum sectional material keeps maximum.And due to the thermal conductivity factor of heat-dissipation aluminum sectional material higher, good heat-transfer effect can be played.
Preferably, in above-mentioned LED lamp: described pressure-casting type heat radiating cup edge is provided with groove.
By adopting this scheme: utilize the upper groove on pressure-casting type heat radiating cup edge to expand the contact area of pressure-casting type heat radiating cup and air, promote its radiating rate.
It is further preferred that in above-mentioned LED lamp: described LED paster selects the SMD2835 type LED paster of 0.2w; Described LED paster has 20, is evenly mounted on cross aluminium base surface.
By adopting this scheme: compared to traditional LED lamp, single paster thermal power is lower, is simultaneously ensureing that the prerequisite of illuminance is ordered paster distribution more dispersion thus make integral heat sink effect better.
Further preferably, in above-mentioned LED lamp: described cross aluminium base is provided with screwed hole, described cross aluminium base utilizes this screwed hole to be secured by bolts on heat-dissipation aluminum sectional material.Described cross aluminium base thickness is preferably 0.7mm.
Compared with prior art, the utility model significantly improves the integral heat sink effect of LED lamp, improves the service life of light fixture, and simplifies processing technology by the structure changing light source substrate, significantly decreases cost of labor.

Detailed description of the invention
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1 of the present utility model as Figure 1-5:
A kind of LED lamp, comprise lamp socket 1, LED driving 2, pressure-casting type heat radiating cup 31, heat-dissipation aluminum sectional material 32 and light source substrate 4, described pressure-casting type heat radiating cup 31 upper end connects heat-dissipation aluminum sectional material 32, lower end connects lamp socket 1; Described pressure-casting type heat radiating cup 31 edge is also provided with uniform groove 311.Described light source substrate 4 comprises the cross aluminium base 41 and LED paster 42 that thickness is 0.7mm, and described LED paster 42 adopts the SMD2835 type LED paster of 0.2w, has 20, is evenly mounted on cross aluminium base 41 surface.Four extension 411 of described cross aluminium base 41 are bent parts, in the upper surface of heat-dissipation aluminum sectional material 32 after four extension 411 bendings of described cross aluminium base 41, described cross aluminium base 41 is provided with screwed hole 412, and described cross aluminium base 41 utilizes this screwed hole 412 to be secured by bolts on heat-dissipation aluminum sectional material 32.Described LED drives 2 to be installed on inside lamp socket 1 and is connected on light source substrate 4 through casting formula heat radiating cup 31 and heat-dissipation aluminum sectional material 32.
In practice: first form light source substrate 4 at the surperficial SMT paster of cross aluminium base 41.After paster, use special fixture by four of light source substrate 4 extension 411 bending formings and be nested in heat-dissipation aluminum sectional material 32 upper surface, and with bolt being fixed as one through both screwed hole 412 realizations.Because the thermal conductivity factor of heat-dissipation aluminum sectional material 32 is higher, extraordinary heat-transfer effect can be played, and thermal capacitance too increases relative to ordinary lamp and lantern.So the radiating effect of entirety is fairly good.
The above; be only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; the technical staff of any skilled is in technical scope disclosed in the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
