Abstract
The utility model relates to an integrated ceramic COB (Chip On Board) bulb lamp, which comprises a lamp cap, wherein the lamp cap is connected with one end of a ceramic shell; a COB light source is arranged in the ceramic shell; an LED (Light Emitting Diode) chip of the COB light source is directly adhered to the ceramic shell; and the other end of the ceramic shell is connected with a light homogenizing housing. According to the integrated ceramic COB bulb lamp, the LED chip is directly adhered to the ceramic shell; since the ceramic shell has extremely high insulation strength and better heat dissipation performance, the heat dissipation level of the LED chip is reduced, the heat dissipation of the lamp is effectively quickened, and the bulb lamp is safe and reliable and has a long service life; and since COB package is adopted, the reassembly process after the packaging of the LED chip of the lamp is reduced and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of LED bulb lamp, particularly a kind of integral ceramics COB bulb lamp.

Summary of the invention
The utility model is made improvement at the problem that above-mentioned prior art exists, namely technical problem to be solved in the utility model provide a kind of simple in structure, production efficiency is high and the integral ceramics COB bulb lamp of rapid heat dissipation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of integral ceramics COB bulb lamp, comprise lamp holder, described lamp holder is connected with an end of ceramic shell, be provided with the COB light source in the described ceramic shell, the led chip of described COB light source directly is bonded on the ceramic shell, and the other end of described ceramic shell is connected with equal light shield.
Further, the whole arranged in series of the led chip of described COB light source are in ceramic shell.
Further, be provided with in the described ceramic shell have short-circuit protection, the power module of open-circuit-protection, overheat protector and constant current function.
Further, described lamp holder is the E27 lamp holder.
Further, be provided with integrated circuit in the described ceramic shell, described integrated circuit is integrated with a high-voltage power pipe.
Compared with prior art, the utlity model has following beneficial effect: this integral ceramics COB bulb lamp directly is bonded in led chip on the ceramic shell, because ceramic shell has high dielectric strength and heat dispersion preferably, therefore reduced the heat radiation level of led chip, accelerated the heat radiation of light fixture effectively, safe and reliable and the life-span is long; Owing to adopt COB(Chip On Board) encapsulation, reduce after the encapsulation of light fixture led chip assembling procedure again, improved production efficiency.
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
