Description

LEDbulb lamp

Technical field

The utility model relates to LED technical field, refers in particular to LEDbulb lamp.

Background technology

In general, whether LED work stablizes, the quality of quality, most important with the heat dispersion of lamp body own.The heat dispersion of lamp body will be got well, and not only will have excellent heat conductivility, also needs to have excellent heat dispersion.The car aluminium fin formula radiator that tradition LEDbulb lamp lamp adopts is the increase in area of dissipation in theory, make it have excellent heat conductivility, but when not installing radiator fan additional, because the spacing of its car aluminium fin is narrow, cause sluggish in air circulation, in fact effective area of dissipation is the Outside Dimensions of radiator, therefore the thermal diffusivity of this radiator is not enough, blackening process can be made in the surface of car aluminium radiator by common practice, to improve its heat loss through radiation ability, but so, not only the acceptance of outward appearance can be given a discount, because structure is still fin-like aluminium flake close-packed arrays, its heat-sinking capability also can not be significantly improved.On the other hand, because car aluminium fin formula radiator itself possesses electric conductivity, radiator is directly exposed in air, if use non-isolated power supply, just have the danger of electrical breakdown, can become this LED cannot by the key factor during electrical equipment certification of the CE HuoULDeng world, and isolated power supply is higher than non-isolated power supply cost a lot, use the LED of traditional vehicle aluminium radiator in order to isolated power supply can only be selected by certification, cause its complex structure, radiating efficiency is low, and security is low, cost also virtual height not under.For reducing costs, traditional LEDbulb lamp also has and adopts Lamp cup as heat-dissipating casing, but this Lamp cup is mostly adopt single hull, and area of dissipation limits to, and causes its radiating efficiency low, to be difficult to accept by market.

Utility model content

The technical problems to be solved in the utility model is to provide the LEDbulb lamp lamp that a kind of heat dispersion is excellent, cost is low.

For solving the problems of the technologies described above adopted technical scheme: a kind of LEDbulb lamp, include lampshade, it be integrated with the aluminium base of LED lamp bead, heat radiation lamp cup, LED drive power, connecting piece of lamp cap and lamp holder, it is characterized in that: the shirt rim of translating into U-shaped outside the tip edge of described heat radiation lamp cup, and the heat-conducting plastic layer of the surface recombination of heat radiation lamp cup insulation.

Adopt the beneficial effect that the utility model brings:

(1) heat radiation lamp cup has outer shirt rim of translating into U-shaped, the basis of traditional Lamp cup significantly adds area of dissipation, the power of whole lamp can be made greatly to improve and do not affect the service life of LEDbulb lamp.

(2) heat dispersion that the heat-conducting plastic that the surface recombination of heat radiation lamp cup insulate compares not moving air is high, and plastic wraps is peripheral at Lamp cup, both can improve radiating efficiency, and can prevent again the danger of electrical breakdown.

(3) contrast traditional car aluminium fin formula radiator, difficulty of processing can be reduced by the shaping Lamp cup of integrated punching, improve working (machining) efficiency, thus cut down finished cost.

(4) surface recombination has heat radiation lamp cup, connecting piece of lamp cap, the lamp holder of heat-conducting plastic, three is closely connected, the insulating properties that they possess itself, whole LEDbulb lamp is made to only have cap part to be conduction, the non-isolated power supply that such LEDbulb lamp can select cost lower, the structure of LEDbulb lamp is simplified, reduces production cost further.

(5) simultaneously, the heat-conducting plastic of compound inslation, can make LEDbulb lamp be more conducive to by the international electrical equipment certification of CE HuoULDeng, thus be conducive to LEDbulb lamp applying as energy-conserving light source of new generation.

Fig. 2 is the explosive view of the utility model LEDbulb lamp.

Detailed description of the invention

As shown in Figure 1-2, a kind of LEDbulb lamp, include lampshade 1, it is integrated with the aluminium base 2 of LED lamp bead, heat radiation lamp cup 3, LED drive power 4, connecting piece of lamp cap 5 and lamp holder 6, aluminium base 2 is fixed on the ring-shaped step of the top end opening of heat radiation lamp cup 3, lampshade 1 covers on the top end opening of heat radiation lamp cup 3, connecting piece of lamp cap 5 is fixedly connected with the bottom end opening of heat radiation lamp cup 3, LED drive power 4 is fixed on connecting piece of lamp cap 5, and be plugged in heat radiation lamp cup 3, lamp holder 6 is fixed on the bottom of connecting piece of lamp cap 5, aluminium base, be electrically connected between LED drive power 4 and lamp holder 6.In the utility model, the shirt rim 31 of U-shaped is translated into outside the tip edge of heat radiation lamp cup 3, certain distance is left between the sidewall of shirt rim 31 and heat radiation lamp cup 3, to guarantee that there is wider heat-dissipating space, and the heat-conducting plastic layer of the surface recombination of heat radiation lamp cup insulation, to guarantee that lamp body has enough insulating properties, be conducive to by the international electrical equipment certification of CE HuoULDeng.

Claims

1. a LEDbulb lamp, include lampshade, it be integrated with the aluminium base of LED lamp bead, heat radiation lamp cup, LED drive power, connecting piece of lamp cap and lamp holder, it is characterized in that: the shirt rim of translating into U-shaped outside the tip edge of described heat radiation lamp cup, and the heat-conducting plastic layer of the surface recombination of heat radiation lamp cup insulation.
