Description
Technical field
The utility model relates to a kind of LED, particularly a kind of LED spotlight of easy heat radiation.
Background technology
LED lamp adopts semiconductor light-emitting-diode technology as a kind of novel environment friendly illuminating product of light emitting source.LED has the features such as power and energy saving, specular removal, low maintenance, shock resistance, safety and environmental protection, long service life, can be widely used in the fields such as various instruction, display, decoration, backlight, general lighting and urban landscape.LED is very responsive to temperature, and junction temperature is higher, and light decay is larger, and the life-span is shorter.And LED lamp, heat of light source is concentrated, in unit are, as heat distributes not in time effectively, LED light will be caused to imitate rapid decay, and therefore, the heat dissipation problem of high-powered LED lamp becomes the key of design, simultaneously the light source of its photograph of LED in a lot of market is uneven, occur a lot of according to less than place.
Along with the development of LED technology, LED be instead of traditional illuminating lamp gradually, but, LED spotlight light source module is used to throw light in the lighting environment of strong Gao Guang, and the heat dispersion of shot-light is all little desirable, even if arrange heat sink bottom light source, the heat that usual light source distributes still can burn out the drive circuit in base, both there is potential safety hazard, virtually added again the use cost of product.
The following problem of existing convection type heat radiation shot-light ubiquity simultaneously: 1, heat dissipation channel design is unreasonable, and what cross-ventilation was dispelled the heat adds the radiating effect that membership weakens fin heat conducting and radiating mode; 2, the problem that lamp body inner product ash affects lighting effects and shot-light service life cannot be solved.
Utility model content
The purpose of this utility model is the LED spotlight providing a kind of a kind of easy heat radiation of easy to use, perfect heat-dissipating in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the LED spotlight of a kind of easy heat radiation designed by the utility model, comprise lamp holder, lamp body, Lamp cup, LED lamp bead and LED circuit board, described LED circuit board to be placed in lamp body and to be electrically connected with fixture wire by line, LED lamp bead is placed in Lamp cup, it is characterized in that: described lamp body is provided with heat radiation end cap, it is inner that Lamp cup is placed in heat radiation end cap, the fin of more than a slice is provided with between described Lamp cup and heat radiation end cap, heat radiation groove is formed between two between fin, described lamp body be provided be evenly distributed radiating groove, described lamp body the inner is also provided with fan, this fan is positioned at the lower end of Lamp cup, venting cavity is provided with between described heat radiation end cap and cup, LED circuit board is placed in fan lower end, above-mentioned heat radiation groove, venting cavity, radiating groove forms the circulation canal of air circulation flow.
Preferably, described fan is quiet fan, and LED spotlight uses its noiselessness.
Preferably, described lamp body is described lamp body is die casting aluminum lamp body.
The LED spotlight of a kind of easy heat radiation that the utility model obtains, this lamp utilizes through reasonably using lamp body to form circulation canal with heat radiation end cap, the design of built-in fans heat radiation simultaneously and venting cavity, also the accumulation of dust can be avoided while utilizing fan cooling, LED circuit board free of discontinuities works under can be made to remain on low-temperature condition, long service life, solve the current life-span short, the shortcoming of high-power LED spotlight can not be used lastingly, the heat energy very first time that can very effectively allow LED produce disperses, radiating effect is very good, reduces use cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the schematic internal view of Fig. 1.
In figure: lamp holder 1, lamp body 2, heat radiation end cap 3, Lamp cup 4, LED lamp bead 5, lampshade 6, fan 10, venting cavity 11, radiating groove 21,22, fin 31, heat radiation groove 32.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As Fig. 1, shown in Fig. 2, the LED spotlight of a kind of easy heat radiation that the utility model provides, comprise lamp holder 1, lamp body 2, Lamp cup 4, LED lamp bead 5 and LED circuit board, LED circuit board known technology does not elaborate, described LED circuit board to be placed in lamp body and to be electrically connected with fixture wire by line, LED lamp bead 5 is placed in Lamp cup 4, Lamp cup 4 is provided with lampshade 6, described lamp body 2 is provided with heat radiation end cap 3, it is inner that Lamp cup 2 is placed in heat radiation end cap 3, the fin 31 of more than a slice is provided with between described Lamp cup 2 and heat radiation end cap 3, heat radiation groove 32 is formed between two between fin 31, described lamp body 2 be provided be evenly distributed radiating groove 21, 22, radiating groove 21, 22 its mainly adopt arcuation radiating groove, described lamp body 2 the inner is also provided with fan 10, this fan 10 is positioned at the lower end of Lamp cup 4, venting cavity 11 is provided with between described heat radiation end cap 3 and cup 2, LED circuit board is placed in fan 10 lower end, above-mentioned heat radiation groove 32, venting cavity 11, radiating groove 21, the circulation canal of 22 formation air circulation flow.Work under LED circuit board free of discontinuities can be made to remain on low-temperature condition, long service life, solves the current life-span short, the shortcoming of high-powered LED lamp can not be used lastingly, the heat energy very first time that can very effectively allow LED produce disperses, and radiating effect is very good, reduces use cost.
