Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can with solve due to COB encapsulation point glue occur rubber powder separate and arogel inhomogeneous, the problem such as photochromic inhomogeneous causing, greatly improve the circle three syringe needle Glue dripping heads of COB luminous light efficiency and colour rendering etc., and comprise the point gum machine of this Glue dripping head simultaneously.
For achieving the above object, the utility model provides following technical scheme: a kind of circular three syringe needle Glue dripping heads, comprise sebific duct, upper body, sebific duct connector, lower case, some glue chamer body and Glue dripping head, sebific duct is arranged on sebific duct connector, upper body is enclosed within on sebific duct, and sebific duct connector embeds in upper body, and some glue chamer body is arranged on the inside of lower case, Glue dripping head has three, is equilateral triangle and is arranged on a glue chamer body.
Preferably, described some glue chamer body is the cavity of the overall glue bet that is made up of three structures of falling positive tetrahedron, each fall the top of positive tetrahedron be provided with an injecting glue syringe needle. The design of positive tetrahedron, is beneficial to colloid and slides along cavity, reduces fluorescent material sedimentation.
Further preferred, between described three adjacent surfaces that fall positive tetrahedron, seamlessly transit, the cross section projection of described some glue chamer body is cloverleaf pattern, is further convenient to phosphor gel and flows, and improve the uniformity of three syringe needle plastic emittings.
Preferably, described sebific duct connector and lower case are to adopt screw fixing seal, are convenient to remove and install.
Preferably, described glue chamer body inside is provided with PP film, can prevent that like this AB is adhesive in the surface of cavity, causes the loss of AB glue.
Preferably, described lower case surface is provided with ripple glaze, to increase friction, skidding occurs while preventing from changing.
On the other hand of the present utility model, a kind of point gum machine that comprises above-mentioned Glue dripping head is also provided.
Adopt the beneficial effect of above technical scheme to be: three syringe needle Glue dripping heads of the present utility model, by improving Glue dripping head number, improve some glue speed on the one hand, be applicable to larger area COB point glue; Simultaneously triangular in shape between three syringe needles, be convenient to realize the some glue of circular area and working in coordination by equilateral triangle and inverted triangle form point glue, can realize the mutual compensation of the fluorescent powder membrane that different batches obtains, make Integral luminous even, improve uniformity, promote light efficiency and colour rendering index; Thereby solve due to the inhomogeneous non-uniform light causing of a glue problem such as colour temperature deviation is large, and colour rendering and light efficiency are not good.
