Embodiment Construction

[0037] see figure 2 , The LED lamp of the present invention includes a reflective cup 1 and LED chips 2, and the LED chip 2 is fixed in the bottom of the reflective cup 1 through a primer 3 having an adhesion function. The primer 3 can be silver glue or insulating glue. The LED chip 2 has positive and negative electrodes, and the reflective cup 1 has positive and negative electrodes. The positive and negative electrodes of the LED chip 2 are welded to the positive and negative electrodes of the reflective cup 1 by wires 4 . The light-transmitting body 5 is packaged on the surface of the LED chip 2 inside the reflective cup 1, and the light-transmitting body 5 fills up and covers the reflecting cup 1, and the material of the light-transmitting body 5 is epoxy resin or silica gel . In this embodiment, epoxy resin is used to coat the LED chip 2 and the reflective cup 1 in a die to form the light-transmitting body 5 . The thickness of the primer is 1 / 4-1 / 3 of the height of th...

Abstract

The invention discloses an LED lamp and an encapsulating method thereof. The size and appearance of an LED chip, a reflecting cup, and an illuminator of the LED lamp are designed according to a certain requirement, so that the light distribution curve of three rays of red, green and blue of the manufactured LED lamp can achieve the three lines-one effect; the light outgoing effect of the LED lamp is more flush; and the light spot and the light shape can be improved. The encapsulating method of the invention is simple, and the manufactured LED lamp can effectively improve the lighting effect of the LED lamp.

Description

technical field [0001] The invention relates to the technical field of light emitting devices, in particular to an LED lamp and a packaging method thereof. Background technique [0002] Due to its high efficiency and energy saving, LED lamps have been used more and more widely, including in the field of lighting, and are also widely used as display devices on displays. [0003] The light distribution curve represents the distribution of light emitted by a lamp or light source in space, and it can be used to record the light output effect of the lamp. see figure 1 , which is the light distribution curve of an existing LED lamp, from figure 1 It can be seen from the figure that the light distribution curves of the red, green and blue primary colors emitted by the existing LED lamps do not overlap together, the light distribution curve is not ideal, the luminous flux of the LED lamp is not good, and the light output effect is not ideal. The reason is that the matching of var...
