Embodiment Construction

[0014] Such as figure 2 and image 3 As shown, the glass bulb 2 and the lamp cap 1 are connected by a metal ring 4, and the manufacturing method is as follows: making a metal ring, the outer diameter of the metal ring matches the inner diameter of the mouth of the lamp cap, and the inner diameter matches the inner diameter of the mouth of the glass bulb. After the metal ring is connected to the glass bulb through high temperature treatment, the inner surface of the metal ring is coated with cement, inserted into the mouth of the lamp cap to combine the edge of the mouth of the lamp cap with the glass bulb, and then fixed by dotting.

[0015] Rationale for this approach:

[0016] The metal ring is made of aluminum alloy, and its Mpa value is about 150. The lamp cap is made of H62 brass with nickel surface treatment, and its Mpa value is about 320. Through the general bubble test of the aluminum lamp cap, the dotting force of 100N is pressed on the aluminum lamp cap point, th...

Abstract

The invention discloses a connection method for a glass bulb and a lamp cap. A metal ring is manufactured, the outer diameter of the metal ring is matched with the inner diameter of the opening portion of the lamp cap, and the inner diameter of the metal ring is matched with the inner diameter of the opening portion of the glass bulb. After the metal ring is processed at high temperature and connected with the glass bulb, the outer ring of the metal ring is coated with plaster, then the metal ring is inserted into the opening portion of the lamp cap to enable the edge of the opening portion of the lamp cap to be combined with the glass bulb, and the glass bulb and the lamp cap are fixed in a dotting mode. The connection method is simple and low in cost, and the boundary dimension of an LED lamp is uniform and reasonable.

Description

technical field [0001] The present invention relates to LED lamps. Background technique [0002] Such as figure 1 As shown, the current manufacturing method of the LED bulb lamp is that the plastic part 3 and the glass bulb 2 are connected by glue, and the lamp base 1 is then connected with the plastic part 3 by dots, the purpose of which is to avoid high temperature of the electronic components. But the disadvantage of this method is that the production cost is high, and the external dimension of the lamp is too long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for connecting the glass bulb and the lamp cap, which reduces the cost, is simple to manufacture, and makes the external dimensions of the lamp uniform and reasonable. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a method for connecting the glass bulb and the lamp c...
