Abstract
The utility model relates to the technical field of car illuminating, in particular to a high-power light-emitting diode (LED) car lamp which comprises a lampshade, a lamp holder and a threaded clamping opening arranged under the lamp holder, wherein a substrate is arranged inside the lampshade and provided with at least one high-power LED patch, a heat dissipation panel is arranged under the substrate, and at least one heat dissipation hole is respectively arranged on two sides of the lamp holder. The high-power LED car lamp is good in heat dissipation effect, can prevent luminous attenuation from being intensified caused by long time work of a high-power LED lamp, and thus service life of the high-power LED lamp is prolonged.
Description
Technical field
The utility model relates to the automotive lighting technical field, especially a kind of great power LED car light.
Background technology
The LED light emitting diode is a kind of solid-state semiconductor devices, and it can directly be converted into light to point, and the characteristics of LED are very obvious, and the life-span is long, light efficiency is high, radiationless and low-power consumption.In recent years, car conour is owing to needs, aerodynamic requirement and demand attractive in appearance in the design, and the shape of taillight is also towards abnormal shapeization and integrative development; LED tradition bubble compares stronger superiority; Response time is fast, energy-conserving and environment-protective, long service life.Yet there is the problem of heat radiation in existing high-power LED illumination design, and heat dissipation technology is the aluminium base heat radiation of limited area now, is encapsulated in high-power LED chip on the very little copper base; Make the lamp holder of 1 watt or 3 watts; Then the lamp holder of several (tens of to up to a hundred) 1 watt (3 watts) is fixed on the aluminium sheet with screw or heat-conducting glue and dispels the heat, owing to have thermal resistance between lamp holder and the aluminium base, the area of dissipation of aluminium base is limited; Cause the LED work calories to derive; Make the led chip temperature sharply rise, the temperature of aluminium base (being the operating ambient temperature of chip) has substantially exceeded the permission operating temperature of chip, the light decay aggravation that works long hours like this and just cause the LED lamp; Brightness reduces, and has shortened service life greatly.
The utility model content
The technical problem that the utility model will solve is: for overcoming the problem of above-mentioned existence; A kind of LED car light of good heat dissipation effect is provided; Solve existing high-powered LED lamp and cause the light decay aggravation because work long hours, brightness reduces, the problem that has shortened service life greatly.
The utility model solves the technical scheme that its technical problem adopted: a kind of great power LED car light; The screw thread bayonet socket that comprises lampshade, lamp socket and be arranged on the lamp socket below; Be provided with substrate in the described lampshade; Described substrate is provided with at least one great power LED paster, and described substrate below is provided with heat sink, and described lamp socket both sides offer at least one louvre separately.
Further, described substrate is an aluminum base plate.
Further, be connected in parallel between the described LED paster, cause the whole LED auto lamp to throw light on thereby the LED auto lamp can not damaged because of one or several LED pasters.
The beneficial effect of the utility model is; The great power LED car light good heat dissipation effect of the utility model; Can prevent high-powered LED lamp and cause the light decay aggravation, thereby prolong the service life of high-powered LED lamp, and be connected in parallel between the LED paster because work long hours; Thereby the LED auto lamp can not damaged because of one or several LED pasters causes the whole LED auto lamp can't throw light on long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. lampshades among the figure, 2. lamp socket, 3. screw thread bayonet socket, 4. substrate, 5.LED paster, 6. heat sink, 7. louvre.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Great power LED car light as shown in Figure 1; Comprise lampshade 1, lamp socket 2 and the screw thread bayonet socket 3 that is arranged on lamp socket 2 belows; Be provided with substrate 4 in the lampshade 1; Substrate 4 is provided with at least one great power LED paster 5, and substrate 4 belows are provided with heat sink 6, and lamp socket 2 both sides offer at least one louvre 7 separately.Wherein, substrate 4 is an aluminum base plate.In addition, be connected in parallel between the LED paster 5, cause the whole LED auto lamp to throw light on thereby the LED auto lamp can not damaged because of one or several LED pasters.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
