Abstract
The utility model relates to the LED illumination technical field, in particular to a high-power LED spotlight. The tradiational light source of the prior art has the problems of short service life, high fee, unstable luminous flux, low color rendering property and unreasonable packaging structure. The high-power LED spotlight improves the photoelectric conversion efficiency of a device by increasing the working current, thereby obtaining higher luminous flux. The adopted technical proposal is as follows: the high-power LED spotlight comprises a lamp cap, a circuit board, a radiator, an LED light source and a lampshade, one end of the radiator is connected with the lamp cap through a fixed base of the lamp cap, the other end is connected with the lampshade through a fixed base of the lampshade, the circuit board and a heat conducting block as well as the LED light source are connected in sequence from the lamp cap end to the lampshade inside the radiator, an insulating board is arranged around the LED light source, therefore, the service life of the light source is long, the lighting effect is good, the electricity saving effect is evident, the luminous flux is stable, the fluctuation does not exist, and the harm of stroboscopic effect does not exist.
Description
Technical field
The utility model relates to the LED lighting technical field, is specifically related to a kind of high-power LED illuminating lamp.
Technical background
There is following shortcoming in the traditional electrical light source: 1, the life-span is short: illuminating lamp has only 1000 hours with the average life span of incandescent lamp, and the average life span of other light sources also has only 3000-8000 hour, and well below the life-span of high-power LED illuminating lamp, maintenance cost is higher.2, expense height: the luminous flux that every watt of electrical power of electric light source produces claims light efficiency, and the light efficiency of ordinary incandescent lamp is 15Lm/w, and the line footpath of service cable is big, makes the initial investment expense bigger.3, luminous flux instability: light sources such as fluorescent lamp, incandescent lamp, high-pressure sodium lamp, sodium vapor lamp all adopt ac power supply, and the fluctuation degree of depth of luminous flux is at 55-65%, and vibration frequency was 100 weeks, and the harmfulness of stroboscopic effect is very big.4, colour rendering is low: colour rendering is represented the reducing degree of light to color, and (general fluorescent lamp colour rendering index is 60-70) sees thing under the lower light of colour rendering, and eyes are low to the resolution capability of color, cause visual fatigue easily.5, encapsulating structure is unreasonable: traditional indicator lamp type LED encapsulating structure, generally be with conduction or non-conductive adhesive is contained in chip in the undersized reflector or on the slide holder, the inside and outside connection back of being finished device by spun gold forms with epoxy encapsulation, its thermal resistance up to 250 ℃/W-300 ℃/W, will cause junction temperature of chip to rise rapidly and epoxy carbonization flavescence because heat radiation is bad, thereby the acceleration light decay that causes device is until inefficacy, even loses efficacy because the stress that thermal expansion rapidly produced causes open circuit.
Summary of the invention
The utility model provides a kind of high-power LED illuminating lamp, with overcome the life-span that prior art exists short, consume big, luminous flux is unstable, colour rendering low and the irrational problem of encapsulating structure.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of high-power LED illuminating lamp, comprise lamp holder 1, wiring board 3, radiator 4, led light source 8, lampshade 9, its special character is: described radiator 4 one ends are connected with lamp holder 1 by lamp holder holder 2, and the other end is connected with lampshade 9 by fixed holder of lampshade 6; Described radiator 4 inside are provided with wiring board 3, heat-conducting block 5 and led light source 8 successively from lamp holder end to the lampshade end; Be provided with insulation board 7 around the described led light source 8.
The material of above-mentioned wiring board 3 is a copper clad plate.
The material of above-mentioned insulation board 7 is an epoxy plate.
The material of above-mentioned radiator 4 and heat-conducting block 5 is an aluminium.
Compared with prior art, advantage of the present utility model is as follows:
1, light source long service life: the theoretical life-span of high-power LED illuminating lamp can reach 100,000 hours, surpasses 50,000 hours actual life, and by lighting every day 10 hours, high-power LED illuminating lamp can be with 5000 days, so high-power LED illuminating lamp can be with more than 10 years.
2, light efficiency height, economize on electricity is remarkable: the light efficiency of great power LED can reach 80-120Lm/w; With compare with the brightness incandescent lamp, high-power LED illuminating lamp can be saved the 80%-90% electric energy, special power saving; Therefore the line of service cable footpath can reduce greatly.Can save initial investment.
3, stroboscopic effect harm is stablized, do not fluctuateed, do not have to luminous flux: high-power LED illuminating lamp all adopts the Constant Direct Current electric current to drive, and can not produce any stroboscopic, without any harm, can effectively eliminate visual fatigue to human body.
4, color developing is good, can not produce colour cast: green illumination lamp requirement colour rendering index should be more than or equal to 85.The high-power LED illuminating lamp colour rendering index can satisfy the requirement of green illumination lamp fully.
