Abstract

The utility model discloses a novel radiating lamp, which is composed of a lamp cap, a lower connector, an upper connector, a lamp cup, an aluminum substrate and an illuminant, wherein the lamp cap is installed at a lower end of the lamp cup via the lower connector, the aluminum substrate is installed at an upper end of the lamp cup via the upper connector, the illuminant is installed on the aluminum substrate, the periphery of the lamp cup is provided with at least two radiating fins with space therebetween, and each radiating fin is internally provided with a hollow pipe. The radiating lamp has the characteristics of good radiating effect, easy processing, small material consumption and low cost, and can be widely applied to lighting systems of various locations.

Description

A kind of heat sinking light fixture

Technical field

The utility model relates to a kind of light fixture, particularly a kind of light fixture with heat sinking function.

Background technology

The LED lamp is owing to good energy-conserving effect, long service life, volume are widely used for a short time, the disadvantage of this type of light fixture is that the substrate caloric value is big, if light fixture radiating effect difference will influence the life-span of light fixture, but also there is potential safety hazard, therefore, this type of light fixture generally all can be provided with a radiator.Want to improve the radiating effect of radiator, prolong the service life of light fixture, mainly consider from two aspects, the one,, utilizing the radiating effect better material, this can increase cost on the one hand undoubtedly; The 2nd,, the structure of change radiator, the structure majority of existing radiator is not too reasonable, needs further to improve.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of good heat dissipation effect, easily processing, heat sinking light fixture that cost is low.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of heat sinking light fixture, form by lamp holder, lower union joint, upper binding head, Lamp cup, aluminium base, illuminator, described lamp holder is installed in the lower end of Lamp cup by lower union joint, described aluminium base is installed in the upper end of Lamp cup by upper binding head, described illuminator is installed on the aluminium base, the periphery of described Lamp cup is provided with at least two fin, leaves the space between each fin, is provided with hollow tube in described each fin.

As improvement of the technical scheme, on described aluminium base, be provided with the light transmission clamshell.The shape of cross section of the hollow tube in the described fin is circular or oval.

The beneficial effects of the utility model are: because each fin of the present utility model is made hollow form, cooling surface area is big, good heat dissipation effect; Hollow tube is easily processed by extrusion modling; Consumptive material is few, and cost is low.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is a structure exploded perspective view of the present utility model;

Fig. 3 is the cross-sectional view of Lamp cup.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of heat sinking light fixture is made up of lamp holder 1, lower union joint 2, upper binding head 3, Lamp cup 4, aluminium base 5, illuminator 6.Lamp holder 1 is installed in the lower end of Lamp cup 4 by lower union joint 2, and aluminium base 5 is installed in the upper end of Lamp cup 4 by upper binding head 3.Illuminator 6 is installed on the aluminium base, and illuminator 6 is made of one or more LED lamps.The periphery of Lamp cup 4 is provided with at least two fin 401, leaves the space between each fin 401, is provided with hollow tube 402 in each fin 401.The shape of cross section of hollow tube 402 can be circular, also can be oval, can also be square, triangle, fall shape such as pyriform.

In order to cover illuminator, light transmission clamshell 7 is installed on aluminium base, light transmission clamshell 7 can be made by safety glass, also can make with the PC material, and light transmission clamshell 7 can also make the whole structure of light fixture more attractive in appearance.

Radiating lamp of the present utility model has good heat dissipation effect, easily processing, the few low characteristics of cost of consumptive material, can be widely used in the illuminator in various places.
