Description

The LED shot-light

Technical field

The present invention relates to a kind of LED shot-light, belong to field of illuminating lamps.

Background technology

The development of LED lighting engineering is maked rapid progress, and begins to develop into today from the eighties of last century sixties, has passed through the change of several generations, and LED illumination market of today has formed certain scale, from the upstream product to the downstream product, has formed streamlined industrial system.The LED shot-light that is used for illuminating product is because advantages such as its energy-saving and environmental protection are being accepted by people, so be seen everywhere on the LED shot-light market of all size model gradually.The Along with people's growth in the living standard, what people pursued will be more extensive, and not only quality will be got well, and outward appearance is more beautiful, the more important thing is to have potential safety hazard, is used to satisfy the use of the different occasions of people.

LED shot-light in the market, specification is uneven, and size is also all lack of standardization.Existing LED shot-light ubiquity temperature too high problem, especially LED PAR20 shot-light cause the heat dissipation problem of this product to be difficult to solve because volume is little, and area of dissipation is limited, have had a strong impact on performance and the life-span of LED.Most of LED shot-lights on the market are in assembling process, and key position all is to fix through machine screws, expends a lot of human and material resources.

Summary of the invention

The objective of the invention is to overcome the defective that prior art exists, a kind of good heat dissipation, easy for installation, technology simple LED shot-light are provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED shot-light; Comprise lens decorative cover, lens, the substrate with lamp pearl, Lamp cup, base, driving power and lamp holder, said substrate is fixed on bottom, Lamp cup cup chamber, and said lens cover directly over the said lamp pearl; Said Lamp cup upper end is threaded with the lens decorative cover; Its lower end is fixedly connected with the base upper end, and said base lower end is connected with cap screw thread, and described base has cavity; Said driving power is installed in the said cavity, has first air vent and second air vent on described lens decorative cover and the Lamp cup.

Further, better in order to make radiating effect, said first air vent is that center annular is distributed in lens decorative cover edge with the center of circle of lens decorative cover; Said second air vent is that center annular is distributed on the wall of cup of Lamp cup with the Lamp cup axis; Described substrate is an aluminium base, and its surface has high thermal conductive silicon fat layer; The one side that is coated with high thermal conductive silicon fat layer on the said substrate contacts with the Lamp cup bottom.

Further, for easy for installation, reduce the workload in the production process, described lens are made up of some monomer lens integral type tilings; Preferred version: described lens are made up of three monomer lens.

Further, for cost and the manufacturing process step that reduces lamp, described base upper end is threaded with the Lamp cup lower end.

Further, in order to mate with general E26/E27 lamp holder, end interface is the hickey that is complementary with the E26/E27 lamp holder under the described base.

Beneficial effect of the present invention: the invention solves the defective that exists in the background technology; (1) on lens decorative cover and Lamp cup wall of cup, all has air vent; These air vents form the cross-ventilation loop; Lens decorative cover and Lamp cup are formed a circulation of air cavity, have broken the structure that traditional lamp integument is sealed in the Lamp cup the inside, make the radiating effect of shot-light more superior; (2) scribble the heat-conducting silicone grease layer at substrate surface, effectively improved the conduction of velocity of heat; (3) lens are made up of three monomer lens one, and convenient the installation can be reduced the workload in the production process; (4) base is threaded with Lamp cup, has reduced the cost and the technology making step of lamp; (5) because radiating effect improves greatly, also improved the delivery efficiency of driving power simultaneously, its more stable work.

The specific embodiment

A kind of LED shot-light shown in Fig. 1-7 comprises aluminium alloy lens decorative cover 1, lens 2, the aluminium base 3 with lamp pearl, Lamp cup 4, plastic feet 5, driving power 6 and lamp holder 7.Said substrate 3 surfaces have high thermal conductive silicon fat layer, and are fixed on bottom, 4 glasss of chambeies of Lamp cup through machine screws.Said lens 2 cover directly over the said lamp pearl, and it is made up of three monomer lens integral type tilings.Said Lamp cup 4 upper ends are threaded with lens decorative cover 1 lower end; Its lower end is threaded with base 5 upper ends; Said base 5 lower ends are threaded with lamp holder 7; And 5 times end interfaces of base are the hickey that is complementary with the E26/E27 lamp holder, and said base 5 has cavity, and said driving power 6 is installed in the said cavity.

Have some first air vents 11 on the described lens decorative cover 1, this first air vent 11 is that center annular is distributed in lens decorative cover 1 edge with the center of circle of lens decorative cover 1.Have some second air vents 41 corresponding respectively on the said Lamp cup 4 with each first air vent 11; This second air vent 41 is that center annular is distributed on the wall of cup of Lamp cup 4 with Lamp cup 4 axis; And the axis of second air vent 41 is parallel with the axis of Lamp cup 4; Adopt this structure, the ventilating opening of second air vent 41 is just aimed at first air vent 11, more helps cross-ventilation.

The one side that is coated with high thermal conductive silicon fat layer on the said substrate 3 contacts with Lamp cup 4 bottoms, has effectively improved the conduction of velocity of heat.

Second air vent 41 on first air vent 11 during work on the air scioptics decorative cover 1 and the Lamp cup 4 forms the cross-ventilation loops, makes the radiating effect of Lamp cup 4 more superior; Lens decorative cover 1 is formed a circulation of air cavity with Lamp cup 4, has broken the structure that traditional lamp integument is sealed in the Lamp cup the inside, efficiently solves the difficult problem of LED shot-light heat radiation.
