It is appreciated that since the LED module sets several LED sub-light sources, it is larger based on its power, and far from scattered On the basis of hot systems or structure, other than solving its radiating requirements, it is necessary to solve its circuit mechanism because energizing excessive production The problem of raw load is larger, i.e., described circuit mechanism can lead to the problem of local component scorification because load is excessive, that is, occur Short circuit problem, at this point, the circuit mechanism is easy to catch fire, there are the danger of fire, greatly threaten user the person and Property safety.

In order to improve security performance, for example, referring to Fig. 2, the front end heat dissipation type illuminator further includes release mechanism 900, release mechanism 900 includes fire prevention solid material filling part 910 and trigger unit 920, bottom plate 110 offer safe cavity 111, The bottom of safe cavity 111 offers triggering hole 112, triggers the inside with safe cavity 111 and mounting cup 120 respectively of hole 112 The accommodating cavity connection, fire prevention solid material filling part 910 is filled in inside safe cavity 111, and trigger unit 920 is set to Hole 112 is triggered, and closes triggering hole 112.For example, the trigger unit has membranaceous or laminated structure, e.g., the material of the trigger unit Matter is high molecule plastic, and when the circuit mechanism catches fire or during failure heat production, the effect based on high temperature, the trigger unit is heated Change.For example, the material of the fire prevention solid material filling part is fire prevention solid material, when the fire prevention solid material is by high temperature During effect, chemical action can occur, volatilize a large amount of fire-retardant gas, e.g., carbon dioxide.

The operation principle of above-mentioned release mechanism 900 is as follows:

When the circuit mechanism short circuit occurred inside and when catching fire, the effect based on high temperature is described in the triggering hole Trigger unit melted by heat makes the triggering hole be connected with the accommodating cavity, in the process, the institute of the safe inside cavity It states fire prevention solid material filling part to be heated and decompose or chemically react, releases a large amount of fire-retardant gas, e.g., carbon dioxide, institute It states fire-retardant gas to be ejected in the accommodating cavity by the triggering hole, based on the fire retardation of the fire-retardant gas, be used for Circuit mechanism described in burning is put out, for avoiding the sprawling of the intensity of a fire, avoids that large-scale fire, security performance higher occurs.

It is appreciated that since several LED sub-light sources are directly mounted at the heat-dissipating pipe, the heat-dissipating pipe bears larger Heat carry, the especially higher situation of power and brightness requirement, therefore, it is necessary to improve the heat dissipation performance of the heat-dissipating pipe Can, in order to further improve the heat dissipation performance of the heat-dissipating pipe, to improve the heat dissipation of the front end heat dissipation type illuminator entirety Performance, for example, referring to Fig. 7, heat-dissipating pipe 500 includes the safe floor 520, heat-conducting layer 530, the heat transfer layer 540 that are cascading With heat dissipating layer 550, safe floor 520 is set towards the installation cavity setting, heat dissipating layer 550 towards the heat-dissipating cavity.

For example, the front end heat dissipation type illuminator of an embodiment, the safe floor includes following mass parts Each component:80 parts~90 parts of silicon nitride, 30 parts~45 parts of titanium dioxide, 2 parts~8 parts of silica, 2 parts~15 parts of kaolin, 0.2 part~0.5 part of 0.5 part~2 parts of light weight calcium and rare earth oxide.For example, the rare earth oxide includes lanthana, oxidation At least one of cerium, praseodymium oxide, europium oxide and terbium oxide, for example, lanthana, cerium oxide, praseodymium oxide, europium oxide and terbium oxide Mass ratio is 1:1:1:1:1.

Above-mentioned safe floor has the advantages of insulation effect is good, and thermal conductivity factor is big and coefficient of thermal expansion is low, in this way, as LED When the heat of light source is directly delivered to the safe floor, the safe floor can be quickly and in time by area near LED sub-light sources The heat transfer of domain aggregation is to the heat-conducting layer, to ensure the normal work of LED sub-light sources.Secondly as the safe floor with LED sub-light sources are in direct contact or closer to the distance, and the heat conduction load undertaken is maximum, and above-mentioned safe floor uses silicon nitride as mainly Raw material, and mixed other materials can have relatively low coefficient of thermal expansion, so as to avoid the safe floor and the heat conduction Gap is generated between layer and the safe floor itself is avoided to generate gap, and then can be to avoid the gap and gap filling air The problem of thermal conductivity factor generated afterwards reduces.Further, since being in direct contact between the safe floor and LED sub-light sources or distance It is relatively near, electric elements easily occur, such as the situation that conducting wire is directly contacted with the safe floor, above-mentioned safe floor is made using silicon nitride For primary raw material, and mixed other materials can have preferable insulating properties, so as to which the safe floor is avoided to be powered, so as to The security performance of the front end heat dissipation type illuminator is improved, safety standard is higher.

For example, the front end heat dissipation type illuminator of an embodiment, the heat-conducting layer includes following mass parts Each component:90 parts~95 parts of nano-graphene fiber, 0.5 part~15 parts of multi-walled carbon nanotube, single-walled carbon nanotube 0.1 part~5 0.1 part~10 parts of part and carbon nano-fiber.

Above-mentioned heat-conducting layer uses nano-graphene fiber as primary raw material, and using multi-walled carbon nanotube, single Pipe and carbon nano-fiber are as auxiliary material so that the heat-conducting layer has larger thermal conductivity factor, and heat-conducting effect is preferable.It needs , it is noted that addition multi-walled carbon nanotube, single-walled carbon nanotube and carbon nano-fiber, can form micro- dissipate in the heat-conducting layer Hot channel, for further improving heat dissipation performance, in this way, can be quick by the heat of the safe floor and institute be transferred in time It states in heat transfer layer.

It should be noted that because the LED sub-light sources shine generation heat pass through before two layers, i.e., described safe floor and institute After stating heat-conducting layer, understand the heat of some and be lost in extraneous air.Further, since the cost of the heat-conducting layer is higher, Itself main reason is that, the primary raw material of the heat-conducting layer nano-graphene fiber higher for manufacturing cost, therefore, based on institute State heat transfer layer heat transfer and heat dissipation load it is relatively small in the case of, the heat transfer layer can use the more common gold in current market Belong to heat sink material, to achieve the effect that reduce cost and obtain preferable heat transfer property.

For example, the heat transfer layer of an embodiment of the present invention, include each component of following mass parts:85 parts~90 parts of copper, 2 parts~4.5 parts of titanium, 0.1 part~0.3 part of nickel, 0.2 part~1.2 parts of magnesium, 0.2 part~0.7 part of iron, 0.2 part~1.2 parts of vanadium, manganese 0.1 part~0.4 part and 0.1 part~0.3 part of chromium.

Above-mentioned heat transfer layer has preferable heat transfer property using what 85 parts~90 parts of copper can make heat transfer layer, so as to More quickly the heat being transmitted on the heat-conducting layer is passed, and then be evenly dispersed in the structure of the heat transfer layer entirety On, to prevent heat from being accumulated on the contact position between the heat-conducting layer and the heat transfer layer, cause hot-spot phenomenon It generates.In addition, above-mentioned heat transfer layer has, thermal conductivity factor is high, perfect heat-dissipating, good mechanical property and lower-cost advantage, such as This, when the heat transfer of the heat-conducting layer gives the heat transfer layer, then the heat that the heat-conducting layer is absorbed into can be more fast It is transmitted to fastly in the heat dissipation, and during heat transfer, the heat of part can also be directly delivered to by the heat transfer layer In extraneous air.

It should be noted that the heat generated when the LED sub-light sources is by three first layers, i.e., respectively described safe floor, After the heat-conducting layer and the heat transfer layer, have relatively large a part of heat and scatter and disappear in air medium in transmission, in addition, Since the primary raw material of the heat transfer layer is copper, heavier mass is therefore, relatively small based on heat dissipating layer heat dissipation load In the case of, the heat dissipating layer can be preferable using heat dissipation effect, and lighter in weight, lower-cost material reduce cost to reach And weight and the effect for obtaining preferable heat dissipation performance.

For example, the heat dissipating layer of an embodiment of the present invention, include each component of following mass parts:70 parts~75 parts of aluminium, 35 parts~45 parts of copper, 0.2 part~0.7 part of magnesium, 0.1 part~0.3 part of nickel, 0.2 part~0.7 part of iron, 0.2 part~0.5 part of manganese, titanium 0.1 part~0.3 part of 0.1 part~0.3 part, 0.05 part~0.1 part of chromium and vanadium.

Aluminium and 35 part~45 part of copper of the above-mentioned heat dissipating layer using 70 parts~75 parts, can be such that the heat dissipating layer still has Preferable heat dissipation performance, so as to ensure that the heat dissipating layer can rapidly dissipate the heat passed over by the heat transfer layer It loses in air medium, e.g., is dissipated in inside the heat-dissipating cavity, and then heat is avoided to be accumulated on the heat dissipating layer, causes Hot-spot phenomenon generates.Relative to the prior art, merely using price costly and the larger copper of quality, above-mentioned heat dissipating layer Both there is good heat dissipation effect, rapidly heat can be lost in air, and there is lighter weight, be easily installed casting, price The advantages of less expensive.Meanwhile relative to the prior art, merely using the poor aluminium alloy of heat dissipation effect, above-mentioned heat dissipating layer tool There is more preferably heat transfer property.

For example, the safe floor, the heat-conducting layer, the heat transfer layer and the heat dissipating layer thickness ratio be 0.5~1.1: 0.1~0.3:3~3.5:4~4.5, for optimizing the structure of the heat-dissipating pipe, for improving heat dissipation performance.
