Abstract
The utility model relates to the field of illumination lamps and discloses a COB (chip on board) spotlight. The COB spotlight comprises a spotlight head and a heat dissipater mounted at the front end of the spotlight head, wherein a drive power supply, a COB light source and a metal reflection cup are mounted in the heat dissipater; one end of the drive power supply is electrically connected with the COB light source, and the other end of the drive power supply is electrically connected with the spotlight head; the metal reflection cup is arranged on the inner wall of the heat dissipater; the drive power supply is a direct-current power supply; an insulated silicon rubber cushion is arranged between the COB light source and the metal reflection cup. Due to the adoption of the COB spotlight, the defective rate of products is greatly reduced and the production efficiency is improved in a manufacturing process.
Description
Technical field
The utility model relates to field of illuminating lamps, relates in particular to a kind of COB shot-light.
Background technology
COB shot-light is the shot-light of a kind of COB of using LED light source as light emitting source.Tradition spotlight light source adopts Halogen lamp LED and great power LED more.Wherein lower, the relatively power consumption of Halogen lamp LED luminous efficiency, illuminated environment temperature rise, service life is short; And the local light efficiency of high-power LED is excessively strong, hot spot is inhomogeneous, has dark place.LED is far superior to traditional lighting product in the aspect of principle of luminosity, energy-saving and environmental protection, and the luminous one-way of LED has formed the perfection support to shot-light luminous intensity distribution.But existing COB shot-light heat dispersion is good not, has low problem in service life.Meanwhile, making in the process of COB shot-light, because reflector great majority are all metal materials, in the process that itself and COB light source are assembled together, easily cause the problem of short circuit, thereby cause the raising of product fraction defective.
Utility model content
The object of the utility model embodiment is: a kind of COB shot-light is provided, in processing and making process, greatly reduces the fraction defective of product, improved production efficiency.
A kind of COB shot-light that the utility model embodiment provides, comprises lamp holder and the radiator that is installed on described lamp base front end; Driving power, COB light source and metal reflective cup are installed in described radiator; Described driving power one end is electrically connected with described COB light source, and the other end is electrically connected with lamp holder; Described metal reflective cup is positioned at described radiator inwall; Described driving power is dc source; Between described COB light source and described metal reflective cup, be provided with SOI rubber cushion.
Optionally, the leading section of described radiator is provided with louvre.
Optionally, described radiator outer wall is provided with the convex tendon for dispelling the heat.
Optionally, described SOI rubber cushion be shaped as " O " shape.
Optionally, the front end of described metal reflective cup is provided with glass cover by snap ring.
Therefore the technical scheme of application the utility model embodiment, by between metal reflective cup and COB light source, SOI rubber cushion being set, thereby makes the two be difficult for causing short circuit in the process of assembling, also with regard to unavoidably the appearance of fraction defective.Meanwhile, described SOI rubber cushion can also make described metal reflective cup and COB light source better press together, and the two is in conjunction with more firm.
Brief description of the drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
The structural representation of a kind of COB shot-light that Fig. 1 provides for the utility model embodiment;
The structure explosive view of a kind of COB shot-light that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
As depicted in figs. 1 and 2, COB shot-light described in the utility model, comprises lamp holder 1 and the radiator 2 that is installed on described lamp holder 1 front end.The material that described radiator 2 adopts is aluminium alloy, and its cost is low, and good heat dissipation effect, can also adopt other metals, certainly such as aluminium simultaneously.In described radiator 2, be one cavity is installed, driving power 3, COB light source 4 and metal reflective cup 5 are installed, and what described driving power 3 adopted is dc source, and its one end is electrically connected with described COB light source 4, and the other end is electrically connected with described lamp holder 1; Why described metal reflective cup 5 does not adopt plastic material, is mainly that it also can adopt aluminum alloy material certainly in order to improve heatproof and the effect after glossing, and it is positioned at described radiator 2 inwalls.In order to solve the short circuit problem of COB light source in existing product 4 and described metal reflective cup 5, thereby SOI rubber cushion 6 is set between the two, it is shaped as " O " shape.
In order to improve the radiating effect of described COB shot-light, how there is protruding convex tendon 7 at the outer wall of described radiator 2.Meanwhile, also have louvre 8 at the leading section of described radiator 2, further improve radiating effect.
For the improvement of technique scheme, be provided with glass cover 10 at the front end of described metal reflective cup 5 by snap ring 9, improve the illumination effect of COB shot-light.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in detailed description of the invention and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
