A kind of bar shaped COB light source including COB lamp plate, the circuit layer being fixed in the COB lamp plate and is fixed on described
LED chip on COB lamp plate, the LED chip are provided with gold thread, and the LED chip is electrically connected by gold thread and the circuit layer
It connects, and is provided with boss on the outside of the LED chip, the boss is an integral structure with the COB lamp plate, and the outside the boss is set
It is equipped with reflector, the reflector is socketed on the boss, due to by being provided with boss, the boss on the outside of LED chip
It is an integral structure with the COB lamp plate, which, which has conveniently to be positioned manually, is installed to COB lamp plate LED chip
In position so that LED chip irradiate come light can be uniform, to achieve the purpose that radiation response is good, and convex
It is provided with reflector on the outside of platform, the reflector is socketed on the boss, which can either prevent LED chip artificial
Touching and dust cause to damage after entering, and LED chip can be irradiated the light come to expansion, therefore have radiation response good
And the characteristics of long service life.
Preferably, the reflector is made of fluorescent powder glue-line and substratum transparent, and the substratum transparent is located at phosphor gel
Layer top, since reflector is made of fluorescent powder glue-line and substratum transparent, the substratum transparent is located above fluorescent powder glue-line, should
Fluorescent powder glue-line, which has, stores and improves luminous efficiency luminous energy, so that LED chip is through substratum transparent photograph
The light shot out at night or dark, remains to see luminous, therefore has the characteristics that radiation response is good.
Preferably, the COB lamp plate is made of aluminium lamp plate layer, copper lamp plate layer and ceramic lamp plate layer, the ceramics lamp plate layer
Below copper lamp plate layer, the copper lamp plate layer is located at below aluminium lamp plate layer, since COB lamp plate is by aluminium lamp plate layer, copper lamp plate layer
It is formed with ceramic lamp plate layer, which has the characteristics that at low cost, copper lamp plate layer conductive good feature and pottery
Porcelain lamp plate layer have the characteristics that it is heat-resist so that the COB lamp plate made has at low cost, electric conductivity and heat-resisting
The good feature of property, and then improve its service life.
Preferably, power interface is provided on the COB lamp plate, the power interface is located at COB lamp plate left end.
Preferably, the COB lamp plate, LED chip, boss and reflector are strip structure.
Compared with the prior art, the utility model advantageous effects are mainly reflected in: the utility model passes through on the outside of LED chip
It is provided with boss, the boss is an integral structure with the COB lamp plate, which, which has, is conveniently positioned manually handle
LED chip is installed to the position in COB lamp plate, so that the light that LED chip irradiates can be uniform, to reach irradiation
The good purpose of effect, and outside the boss is provided with reflector, and the reflector is socketed on the boss, which can
Enough prevent LED chip manually touched and dust enter after cause to damage, and LED chip can be irradiated come light to expand
Greatly, therefore have the characteristics that radiation response is good and long service life, and reflector is made of fluorescent powder glue-line and substratum transparent,
The substratum transparent is located above fluorescent powder glue-line, which, which has, stores and improve the effect that shines luminous energy
Rate so that LED chip through substratum transparent irradiate come light at night or dark, remain to see it is luminous, because
This has the characteristics that radiation response is good, and COB lamp plate is made of aluminium lamp plate layer, copper lamp plate layer and ceramic lamp plate layer, the aluminium lamp
Plate layer has the characteristics that at low cost, the conductive good feature of copper lamp plate layer and ceramic lamp plate layer have heat-resist spy
Point so that the COB lamp plate made has the characteristics that at low cost, electric conductivity and heat-resist, and then improves and makes
With the service life, the utility model structure is simple, and design rationally, accords with the demands of the market, and is suitble to large-scale production.
