Abstract
A large-power light-emitting diode (LED) street lamp relates to the technical field of lighting and is characterized in that a radiating fin is arranged below a light source base of the large-power LED street lamp. After the radiating fin is connected with the light source base, the cross section is in a semi-cylindrical shape. Compared with the prior art, because of the additional radiating fin, the heat dissipated by the large-power LED street lamp can be evenly and rapidly conducted to the radiating fin and dissipated, accordingly, the temperature of an LED lamp bead can be effectively controlled, normal work of an LED lamp bead chip is guaranteed, and fault rate is effectively reduced. The heat absorption speed is fast, heat conduction is even, heat dissipation is good, luminous efficiency of an LED light source is effectively improved, service life of an LED is prolonged, and using reliability of a large-power LED area light source is improved.
Description
Technical field
The utility model relates to lighting technical field, is specifically related to a kind of high-power LED street lamp.
Background technology
Under the background that the worry of current global energy shortage raises once again; Energy savings is the important problem that we shall face future; At lighting field; The application of LED luminous product is just attracting common people's sight, and LED has numerous advantages such as light efficiency height, long service life, energy-saving and environmental protection, more and more widely be applied to various fields.Present various white light LED lighting device mainly adopts the small-power white light LEDs to do.Like the street lamp of the spot of the bulb of 1-5W, 15-20W and 40-60W, projecting lamp etc., these light fixtures have used tens to a hundreds of white light LEDs, complex manufacturing, poor reliability, fault rate height and luminance shortage.If change high-powerly, in case it is bad to dispel the heat, will cause the led light source luminous efficiency low, shorten the service life of white light LEDs, this also is the problem that LED lighting industry is faced.
The utility model content
The utility model technical problem to be solved is to provide a kind of simple in structure, energy-conserving and environment-protective, high-power LED street lamp that radiating efficiency is good.
The utility model technical problem to be solved adopts following technical scheme to realize,
A kind of high-power LED street lamp is characterized in that: below the high-power LED street lamp light source base, be provided with fin, described fin is connected the back cross section and is half-cylindrical with light source base.
Described fin is fixedly connected through welding manner with light source base.
Described fin is the punching press fin structure.
The beneficial effect of the utility model is: this practicality is newly compared with prior art owing to increase the fin of knowing clearly; Make heat that the high-power LED street lamp light source distributes evenly apace to fin conductive and distribute; Thereby the temperature of LED lamp pearl is effectively controlled; Guarantee the operate as normal of LED lamp pearl chip, effectively reduced fault rate; Heat absorption speed is fast and conduction is even, good heat dissipation effect, has effectively improved the led light source luminous efficiency, has prolonged the service life of LED, has improved the reliability that high-power LED surface light source uses.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; A kind of high-power LED street lamp is provided with fin 2 in high-power LED street lamp light source base 1 lower portion, and fin 2 is connected the back cross section and is half-cylindrical with light source base 1; Fin 2 and light source base 1 are fixedly connected through welding manner, and fin 2 is the punching press fin structure.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
