Abstract
The utility model discloses a bulb. The bulb comprises a mounting base (1) which is connected with a power supply; the mounting base (1) is provided with a mounting plate (11) which is provided with a plurality of circuit boards (2); the bulb also comprises a lampshade (3) which is arranged on the mounting base (1) and covers the lighting circuit boards (2); the end portion of the mounting base (1) is provided with a convex platform (131) which extends into the lampshade (3); the mounting plate (11) is arranged on the convex platform (131); the edge of the convex platform (131), which is located on one side of the mounting plate (11), is provided with a circular arc chamfering (15) for reflecting the light.
Description
[technical field]
The utility model relates to a kind of bulb, especially a kind of LED bulb.
[background technology]
The LED bulb is because the illuminating effect of light circuit plate installation meeting to bulb exerts an influence, and what in existing LED bulb, the light circuit plate was installed employing is at right angle setting, and this mounting means can produce the large tracts of land dark space at the bulb tail end.
[utility model content]
In order to solve deficiency of the prior art, provide a kind of simple in structure, reduce the dark space area effective, bulb efficiently easy to process, the technical scheme that the utility model adopts is:
A kind of bulb, comprise the mount pad that connects power supply, be provided with installing plate on described mount pad, be provided with some circuit boards on described installing plate, also include and be arranged on mount pad the lampshade that covers the light circuit plate, described mount pad end is provided with the boss that stretches into lampshade, and described installing plate is located on boss, and the edge that is positioned at installing plate one side at described boss is provided with the circular arc chamfering of reflection ray.
Described circuit board is graniphyric and tilts laterally, the angle α angular range of described circuit board and installing plate is 70 °～80 °, described circuit board is superimposed to glued joint by two aluminium bases and forms, and is provided with uniformly some transversely arranged lamp pearls on described each aluminium base.
The angle α angular range of described circuit board and installing plate is 73 °～77 °.
Described mount pad includes the connector that connects power supply, also include mounting plate and play the lamp socket of radiating effect, be provided with insulator foot between described lamp socket and connector, described circuit board is connected with connector by wire, described insulator foot edge rounding off face.
Adopt the bulb structure of technique scheme simple, only need to process circular arc chamfering at the seamed edge of close circuit board one side of mount pad and just light can be arrived to larger surface area by diffuse reflection, and be provided with arc-shaped transitional surface on base, make at the connection power supply and make to be tightly connected better.
