Abstract
The utility model discloses an efficient angle-adjustable COB light source. The COB light source includes a COB bracket, an LED chip, a wiring board and a fluorescent layer, the COB bracket is made of metal material through integral molding, the COB bracket is provided with a silver coating, a substrate used for welding the LED chip is arranged in a middle part of the COB bracket in a recessed manner, the fluorescent layer is arranged on the substrate, an edge of the substrate is provided with a reflective surface, the reflective included angle of the reflective surface is 50 to 180 degrees, and the reflective included angle can be arranged according to the lighting need of the light source. The COB bracket of the efficient angle-adjustable COB light source can be manufactured in batches through methods such as die casting, forging, and stamping, and finally silvering treatment is performed, the process is simple, and the substrate of the COB bracket and the reflective surface have good reflective effects, thereby enabling the COB light source in the utility model has an more excellent lighting effect than a conventional COB light source.
Description
Technical field
The utility model relates to the adjustable COB light source of a kind of efficient angle.
Background technology
COB refers to Chip-On-Board, by small-power chip direct package to quick heat radiating on substrate, chip area is little, and radiating efficiency is high, drive current is little, thereby has the high-cooling property of low thermal resistance, high thermal conductance, there is following characteristics than common SMD low-power light source: brightness is higher, thermal resistance little (<6 DEG C/W), light decay is less, and aobvious finger is higher, hot spot perfection, the life-span is long.But conventional COB support is all to adopt the substrate of aluminum, and on this aluminium base overlay film, utilize the metal covering of aluminium matter to carry out reflective, its reflective effect is general, and complex manufacturing is loaded down with trivial details.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the good and technique of a kind of light efficiency the simple adjustable COB light source of a kind of efficient angle.
The utility model solves the technical scheme that its technical problem adopts:
The COB light source that a kind of efficient angle is adjustable, comprise COB support, LED chip, terminal block, fluorescence coating, described COB support is made by metal material is one-body molded, and be provided with a silver coating at COB support, described COB mid-stent depression is provided with one for welding the substrate of LED chip, described fluorescence coating is arranged in this substrate, is provided with reflective surface at the edge of this substrate, and the reflective angle of described reflective surface is 50 °-180 °.
Described COB support is made by ferrous material is one-body molded.
Described COB support is made by copper material is one-body molded.
Described COB bracket edge place is provided with some location divisions.
The beneficial effects of the utility model are: the COB light source that a kind of efficient angle is adjustable, comprise COB support, LED chip, terminal block, fluorescence coating, described COB support is made by metal material is one-body molded, and be provided with a silver coating at COB support, described COB mid-stent depression is provided with one for welding the substrate of LED chip, described fluorescence coating is arranged in this substrate, edge in this substrate is provided with reflective surface, the reflective angle of described reflective surface is 50 °-180 °, reflective angle can need to arrange according to the illumination of light source, COB support of the present utility model can be by die casting, forge, the manufacture in batches of the modes such as punching press, finally do silver-plated processing, technique is simple, make substrate and the reflective surface of COB support there is good reflecting effect, make to be had than the more excellent illuminating effect of traditional C OB light source by COB light source of the present utility model.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
