The specific embodiment

1-7 describes the utility model below with reference to accompanying drawings.

Fig. 1 is the stereogram according to the LED lamp of the utility model, and Fig. 2 is the exploded perspective view of LED lamp according to the utility model shown in Figure 1.

Shown in Fig. 1 and Fig. 2, comprise top cover 1, signal LED 2, signal LED PCB 3 (signal LED printed circuit board (PCB)), holding wire 4 (invisible in Fig. 1), reflector 5 (invisible in Fig. 1), reflector retainer 6, color LED 7, color LED PCB 8 (color LED printed circuit board (PCB)), elastic component 9 (invisible in Fig. 1), basic shell 10 (invisible in Fig. 1) and pedestal 11 according to the LED lamp of the utility model.

Top cover 1 is the cylindrical shape with flange, covers on the signal LED PCB 3.Signal LED PCB 3 is provided with low power signal LED 2, and in this example, signal LED 2 is positioned at the center of signal LED PCB 3 upper surfaces.Signal LED PCB 3 is installed on the reflector 5.In this example, reflector 5 has four reflectings surface 51 (in Fig. 2 only visible wherein two).Four color LEDs 7 are arranged on the color LED PCB 8.Said four reflectings surface 51 correspond respectively to said four color LEDs 7.Reflector 5 is installed in the reflector retainer 6.Reflector retainer 6 is processed by Heat Conduction Material, for example is made of metal.Reflector retainer 6 is totally cylindrical, and its opened upper end is used to hold reflector 5, and its bottom forms the surface with hole, and this will specifically describe in the back.Base shell 10 snaps fit together through the elastic component 9 that is arranged between the two with reflector retainer 6.Elastic component 9 for example can be a rubber, perhaps alternately, can be processed by any elastomeric material.Base shell 10 is contained in the pedestal 11.Each component-assembled shown in Fig. 2 is obtained LED lamp shown in Figure 1 together.

In LED lamp according to Fig. 1 and Fig. 2; At first be reflected four reflectings surface 51 of device 5 of the light that sends from color LED 7 and signal LED 2 reflex on the reflector (reflector is positioned at the side near pedestal 11) of car light, and then the direction reflection of cup towards top cover 1 that be reflected.At last, the light of the cup reflection of being reflected sends out through a top cover 1, thereby irradiates the light with expectation identification pattern through being arranged on identification pattern on the top cover 1 etc.

Fig. 3 vertical sectional block diagram that its part is shown that to be LED lamp shown in Figure 1 obtain along its longitudinal centre line, Fig. 4 are the longitdinal cross-section diagrams of the LED lamp shown in Figure 1 obtained along the center line A-A among Fig. 1.Fig. 3 and Fig. 4 are used to help to understand the structural relation of using heat-conducting glue to fix between reflector retainer 6 and the color LED PCB 8, thereby in Fig. 3 and Fig. 4, have saved and the irrelevant parts of said structure relation.Specifically describe below in conjunction with Fig. 1-4 pair of said structure relation.

In LED lamp according to the utility model shown in Figure 3, on the upper surface 13 of color LED PCB 8, be furnished with the copper cash (not shown in FIG.), color LED 7 is fixed on the copper cash.Use heat-conducting glue to be adhesively fixed between reflector retainer 6 and the color LED PCB 8.Particularly, the basal surface 12 of the bottom of reflector retainer 6 is fixed with each other through heat-conducting glue with the upper surface 13 of color LED PCB 8, and this moment, LED PCB 8 top color LEDs 7 passed from the hole that is arranged on the reflector retainer 6, and are as shown in fig. 1.Here, heat-conducting glue can be EA series or the serial heat-conducting glue of buying from Dow Corning Corporation of DA, also can be the heat-conducting glue of buying from 3M company.It will be appreciated, of course, that it also can is the heat-conducting glue of buying on other markets.Because reflector retainer 6 is fixed together through heat-conducting glue and color LED PCB8 on its whole basal surface 12; Thereby has enough big contact area between reflector retainer 6 and the color LED PCB 8; Thereby can be more effective with heat from the basal surface 12 that color LED PCB 8 passes to reflector retainer 6, be delivered to reflector retainer 6 integral body of processing by Heat Conduction Material by basal surface 12 again.That is to say that reflector retainer 6 dispels the heat with color LED PCB 8 jointly, thereby has increased the surface area that is used to dispel the heat, thereby can more effective LED be dispelled the heat.

In addition, because heat-conducting glue need could be realized its effect that is adhesively fixed through hot setting, and to the control relative difficult of heat-conducting glue thickness, thereby the defective that radiating effect descended because of heat-conducting glue thickness is blocked up appears easily in the prior art.The utility model has solved this technical problem equally.

Concrete; Referring to Fig. 1-2 and Fig. 4; Base shell 10 presses color LED PCB8 through elastic component 9 and between basic shell 10 and reflector retainer 6, produces suitable pressure; Have very thin thickness and the heat-conducting glue that is between the two is made for through hot setting under this suitable pressure, for example be preferably 0.1mm, thereby between basic shell 8 and reflector retainer 6, realized lower thermal resistance.Like this, the heat that on LED PCB 8, produces just can be through the more effective reflector retainer 6 that is delivered to of the suitable heat-conducting glue of thickness, and then through the reflector retainer processed by Heat Conduction Material 6 heat is discharged, thereby has further improved radiating efficiency.

Fig. 5 is the plan view from above that the bottom of the reflector retainer of when pedestal 11 directions are observed, seeing from top cover 16 is shown, and Fig. 6 is the side view of reflector retainer 6, and Fig. 7 is the stereogram of reflector retainer 6.

Can find out that with reference to Fig. 1-2 and Fig. 5-7 reflector retainer 6 is cylindrical shapes of open-top, its bottom is formed with five holes, comprises that be used for centre bore 61 that electric wire 4 passes and all the other four that are positioned at bottom centre are used for the hole 62 that color LED 7 passes.Four holes 62 can be mutually an angle of 90 degrees as shown in Figure 5 and be arranged on the periphery of base plane, also can otherwise arrange based on the actual application requirements.

LED lamp color LED PCB 8 according to the utility model is provided with four color LEDs 7.Certainly, as it will be appreciated by those skilled in the art that the quantity of color LED 7 can change according to the demands of different of practical application, and also can be according to actual needs to the demands of different of color and the LED that uses other colors to send the light of desired color.Be further appreciated that the hole on the reflector retainer 6 quantity can for LED PCB 8 on corresponding other quantity arbitrarily of the quantity of color LED 7.

When we change electric current, also can satisfy the taillight requirement according to the LED lamp of the utility model.

In addition, even in rugged environment, for example when temperature 65 is spent, also can be good at heat radiation according to the LED lamp of the utility model.

According to the LED lamp of the utility model, it highly is about 46.6mm, and width is about 26.5mm, and the size of its size and the current Halogen lamp LED that in car light, uses (highly be about 45mm, width is about 26.5mm) much at one.This size characteristic according to LED lamp of the present invention can directly mate it with the existing pedestal (for example BAY15 pedestal) in the automobile product, thereby has extensive applicability.

The signal lamp and stopping light and the taillight that can be used as automobile according to the LED lamp of the utility model.

To understand, the improvement on those skilled in the art can make a large amount of technology and use the utility model, and can not break away from the utility model scope required for protection thus.
