Wide-angle light-emitting diode (LED) lamp

Abstract

The invention discloses a wide-angle light-emitting diode (LED) lamp. The lamp comprises a lamp holder, and a driving power, a lamp body and a lamp panel which are electrically connected with the lamp holder, and a bulb shell, wherein the lamp panel is arranged on the lamp body; an LED light source is arranged on the lamp panel; the bottom of the bulb shell is connected with the lamp body, and the top of the bulb shell is coated or electroplated to form a reflective panel; and moreover, lights can penetrate through the central part of the top of the bulb shell. Compared with the prior art, the top of the bulb shell is coated or electroplated, so that the reflective panel is formed on the top of the bulb shell and can effectively reflect the lights downward; and moreover, the lights can penetrate through the central part of the top of the bulb shell and also can be directly transmitted, reflection and collineation commonly act to form a required wide angle, and furthermore, the thickness of the coating or the electroplating can also be adjusted to uniformly distribute the lights. The lamp is lower in cost, simple in assembling and less in light loss.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a large-angle LED lamp. Background technique [0002] It is difficult for general LED bulbs to achieve a large angle, limited by the shape of the bulb, so the angle basically does not exceed 200°. [0003] The existing design of large-angle LED lights is generally to set a protruding multi-faceted base on the radiator, and the LED lamp beads are attached to three or more aluminum lamp panels, and then the aluminum lamp panels are attached to the multi-faceted panels. on different side walls of the shaped base. Although this design can increase the angle, it will be poor in heat dissipation, because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase the material cost, and it will also increase the cost during the assembly stage. It will increase the difficulty of assembly, th...

Problems solved by technology

Although this design can make the angle larger, it will be poor in heat dissipation because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase material costs, and it will also increase the cost of materials during the assembly stage. Will increase the difficulty of assembly, thereby increasing labor costs

[0004] There are also some existing large-angle LED lamp designs that use multiple rod-shaped LEDs or multiple strip-shaped substrates to achieve large angles, but the disadvantages of these designs are poor heat dissipation and complicated processes; Power, difficult to produce, and can not guarantee the life
