Problems solved by technology

Correspondingly, there are also some proposals that put forward the technical proposal of attaching the substrate with light-emitting chips on the bulb shell, but the problem brought about by such a solution is that the light-emitting chips are excessively concentrated on the top and tail of the bulb shell, resulting in difficulty in heat dissipation, The technical problems of unsatisfactory luminous uniformity and uncontrollable luminous parts, the purpose of the present invention is to solve the above technical problems

Embodiment Construction

[0036] Those skilled in the art understand that the present invention mainly provides an LED lamp with good heat dissipation performance, and the realization of the heat dissipation function mainly depends on the LED light-emitting chip of the LED lamp being close to the LED bulb shell, so that the LED light-emitting chip can be separated from the external environment by a shorter distance Close to ground, so that the LED light-emitting chip can more directly contact the external environment, and realize the heat dissipation of the LED light-emitting chip more simply and conveniently. Further, those skilled in the art understand that the shape of the bulb shell of the LED lamp can be circular, rectangular, or any other shape, which does not affect the essence of the present invention and will not be repeated here.

[0037] specifically, figure 1 A schematic structural diagram of an LED lamp according to a specific embodiment of the present invention is shown. Further, those s...

Abstract

The invention provides an LED lamp. The LED lamp comprises an LED bulb shell, a substrate and an LED light-emitting chip set. One side of the substrate (2) is attached to the inner surface of the LED bulb shell (1), the LED light-emitting chip set (3) is attached to the other side of the substrate (2), and comprises one or more LED light-emitting chips, and the LED light-emitting chips are in series connection through a bonding wire (22), anodes of the LED light-emitting chips are electrically connected to the substrate (2), and cathodes of the LED light-emitting chips are connected with a flexible circuit board (4) to form a power supply loop with a power source. The LED light-emitting chips are tightly attached to the LED bulb shell, the LED light-emitting chips can be in full contact with the bulb shell, the LED light-emitting chips can be emitted to the outside more easily, and the heat dissipation efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp, in particular to an LED lamp with good heat dissipation performance. Background technique [0002] With the large-scale application of LEDs, the advantages of being a new light source for emerging lighting are becoming more and more obvious, but at the same time, the price, the unidirectional luminescence of LEDs and the need for large-area heat dissipation devices for LEDs. [0003] The troubles of the following issues have increasingly become part of the obstacles to the development of LED lighting. [0004] A. Price: LED lighting is composed of four major parts: LED light source, power drive, LED cooling device and bulb structure. As the price of LED light source continues to drop, the cost of the other three parts becomes severe. [0005] B. Large cooling device [0006] Because LEDs generate a lot of heat when they emit light, in order to protect the stable perform...
