Description

A kind of embedded type LED spot lamp

Technical field

The utility model relates to a kind of lighting device, particularly a kind of embedded type LED spot lamp.

Background technology

Along with scientific and technological progress, LED shot-light has been widely used in the illumination such as household, business place with its energy-conservation advantage.But all the time, LED shot-light exists technological difficulties, and that is exactly the heat dissipation problem that how to solve better LED wafer, if the heat dissipation problem of LED wafer can not get good solution, the luminous efficiency of LED wafer will decay soon so, and the service life of LED shot-light will be very short.The approach of the heat dissipation problem of current common solution LED wafer is to adopt aluminium that pyroconductivity is higher as depositing the carrier that carries LED lamp pearl, namely usually said radiating block.The aluminium radiating block of existing LED shot-light, its thermal column center is all hollow conventionally, can save like this aluminium, cost-saving, still, owing to being hollow design, its hot memory space is limited, dispels the heat also unsatisfactory.In addition, the aluminium radiating block of existing LED shot-light, its periphery is the aluminium matter radiator shutter distributing radially, have sharp corner angle, have even with sharp thorn point, very difficult to handle, make troubles to production, installation, also there is potential safety hazard, and this radiator structure that only has the aluminium matter radiator shutter distributing radially, its radiating effect neither be very good.So, also need further improvement for the radiator structure of LED shot-light.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of to the radiating effect of LED wafer better, do not prick the hand, produce, install very convenient, without the embedded type LED spot lamp of potential safety hazard.

The utility model solves the technical scheme that its technical problem adopts: a kind of embedded type LED spot lamp, comprise LED lamp holder and the radiating piece of being located at LED lamp holder afterbody, described radiating piece is by the integrated circular cylinder of aluminium, the periphery of described circular cylinder is heat dissipating ring, the center of circular cylinder is solid thermal column, between thermal column and heat dissipating ring, is connected by equally distributed fin radially.

The utility model has following preferred technical scheme:

The head of described thermal column is provided with one for depositing the pit of LED.

The head of thermal column is blocked the marginal portion of LED be fixed in the front of described LED with an annular outer cover.

In described LED lamp holder, be also provided with a LED prefocus cup in the front of annular outer cover.

The sheet number of described fin is 16 to 20.

The sheet number of described fin is 18.

The beneficial effects of the utility model are: radiating piece is better to the radiating effect of LED wafer, and radiating piece is not pricked the hand, produce, install very convenient, without potential safety hazard, radiating piece of the present utility model adopts the mode of one heat radiation, does not form secondary thermal resistance, and embedded type LED spot lamp has been reached to better radiating effect, can, better for LED heat radiation, extend its service life.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of embedded type LED spot lamp of the utility model, comprise LED lamp holder 1 and the radiating piece 2 of being located at LED lamp holder 1 afterbody, described radiating piece 2 is by the integrated circular cylinder of aluminium, the periphery of described circular cylinder is heat dissipating ring 21, the center of circular cylinder is solid thermal column 22, between thermal column 22 and heat dissipating ring 21, is connected by equally distributed fin 23 radially.The heat dissipating ring 21 of the periphery of above-mentioned solid thermal column 22, circular cylinder, is all conducive to the extraneous conduction of LED shot-light and distribute heat, and effectively extends the service life of LED shot-light.In addition, heat dissipating ring 21 prick the hand, produce, install very convenient, also without potential safety hazard.

The utility model has following preferred technical scheme:

The head of described thermal column 22 is provided with one for depositing the pit 221 of LED3, as shown in Figure 2, this pit 221 is the height in order to coordinate the LED prefocus cup 5 of mentioning below, there is no other essential meaning, do not needing under the situation of engagement height, can not design this pit.

The head of thermal column 22 is blocked the marginal portion of LED3 be fixed in the front of described LED3 with an annular outer cover 4, as shown in Figure 3, annular outer cover 4 as shown in Figure 4 for LED3.

In described LED lamp holder 1, be also provided with a LED prefocus cup 5 in the front of annular outer cover 4, LED prefocus cup 5 as shown in Figure 5.

The utility model is for reaching better radiating effect, the sheet number of described fin 23 is preferably 16 to 20, the air gap between fin can reach more rational state for heat transfer heat radiation like this, in the time that the sheet number of fin 23 is set as 18, it can reach optimum state for cross-ventilation radiating effect.

Radiating piece 2 of the present utility model is by the integrated entirety of aluminium, heat radiation is all one, area of dissipation is large, radiating piece itself does not exist and connects the gap coordinating, do not form secondary thermal resistance, be more conducive to heat radiation, the gap length of fin has taken into full account cross-ventilation speed, thereby promote heat dispersion, made radiating effect of the present utility model very good.

In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
