Principle explanation of the present utility model：

All of LED illumination lamp, has the relatively large radiator of volume and driving power supply.Realize one 20～ The independent electric light source of 100W, cannot clearly be realized by existing LED illumination mentality of designing.First have to remove the larger drive of volume Galvanic electricity source, then removes the larger radiator of volume.Based on 201410211945.8 He of this utility model people Application No. The method of the Chinese patent applications such as 201410214074.5, can be by driving power supply reduction in bulk to electric light making driving power supply Among the lamp holder in source, in such as E40 or E27 screw sockets, the problem of the placement of driving power supply has been successfully solved.

Remaining issues is that how to remove bulky radiator be key point of the present utility model.According to radiating reason By, realize that radiating there are three approach, 1. thermal convection current, 2. conduction of heat, 3. heat radiation.Radiator be thermal convection current be achieved it is main Device, this is the basis of current all integration LED assembly light illumination mode heat dissipation designs.But realize removable, standard The independent electric light source changed this not enough, independent electric light source often works in confined spaces such as lampshades, active to wandering Heat will fail.

One people in window can experience with warm sunlight impinges upon, and glass pane is not warm, and this is that heat ray (can See light wave and infrared light-wave) radiation；Winter warm sunlight shines into the temperature that plastic vegetable greenhouse is improve in canopy, makes canopy Interior Spring is very much in the air, and temperature of shed does not scatter and disappear to outside cold canopy, and this is also the radiation of heat ray, and the heat ray of sunlight can be with Penetrate booth and far infrared that indoor intensification is formed cannot then penetrate booth.It is former that this utility model introduces heat ray radiation Reason, i.e. heat ray, 1. pass through, 2. reflect, 3. absorb.In electric light source (bulb) design light is made to appear bulb as much as possible Shell, outside energy is projected bulb；The bulb assembly that heat ray can not be passed through is reflector design, reflected light back is worn again Go out bulb housing；Heat radiator component can not reflect or through the part coating black Heat Conduction Material of heat ray, make bulb assembly whole Body improves external thermal-radiating ability.Thermal-radiating ability depends on the area of heat radiator and temperature (4.2 sides with temperature It is directly proportional).It is one of key link of the present utility model that bulb assembly bulk temperature is improved relative to LED chip temperature, is sent out The critical closely connected tight heat slinger of optical assembly, heat slinger should press close to bulb housing as far as possible, and bulb housing adopts tubular-shaped structures, on the one hand Intraware, particularly high-power bulb can be supported using bulb housing, on the other hand, be conducive to the heat on heat radiation component Transmit to bulb housing.Filling heat-conducting gas in LED electric light sources (bulb), makes the heat on luminescence component by heat such as heat slingers The rapid soaking of radiation assembly, lifts rapidly controllable (design) temperature including the whole bulb temperature including bulb housing, as far as possible Reduce the temperature difference of LED chip and surrounding heat radiation part on luminescence component.To improve swept area, from clear glass shell for most It is good, Jing tests, glass shell passes through visible light wave and the ability of infrared light-wave is all very strong, while glass shell relative area is larger, An important result of the present utility model be glass shell internal area and external area to being all effective during external radiation, in glass While shell temperature is enhanced, the radianting capacity of electric light source (bulb) is substantially increased；It is of the present utility model that another is important Effect is the fabulous insulant of glass, makes whole bulb realize high efficiency insulation, so as to be accessible to global various safety marks Alignment request.All parts such as the heat slinger of bulb, heat radiation support and bulb housing constitute heat radiation components, are that heat radiation sets The successful another key link of meter, its area are closely related with bulb power.This utility model is successfully gone by above-mentioned design Traditional large volume convector radiator is fallen.

It is of the present utility model to also have an important result to be less in spending using the improved lamp adapter assembly 2 of this utility model On the premise of make bulb that there is superelevation barrier propterty, even if being not easy in being positioned over water into water, so extend bulb be suitable for Scope, reduces light fixture complexity, reduces light fixture cost.

From another angle, luminescent device is mounted in bulb, and no matter how luminescent device improves, or LED or other, as long as cold light source, luminous efficiency is not 100%, and this utility model is all suitable.

Described lamp adapter assembly 2 can be based on 201210253574.0 Chinese patent Shen of this utility model people Application No. Please.The drive component, can be based on this utility model people Application No. 201410211945.8 and 201410214074.5 Come the driving power supply that makes, it is driving by 6 sections of LED load point to the method for Chinese patent application, it is possible to obtain higher electricity Source efficiency (is more than 99%), only in this way when LED bulb power is higher, could place driving power supply in lamp adapter assembly, so that In being not in overheated to make power work unstable.Otherwise, when bulb power is larger, lamp adapter assembly cannot externally remove driving The heat sent by power supply；Based on this power source design, have with low cost or cost free with the LED bulb that this utility model builds For dimming function.
