Problems solved by technology

[0003] Since LED lamps are more energy-saving than incandescent lamps during use and have a longer service life, the incandescent lamps on the existing market are gradually replaced by LED lamps. When the inventor of the application uses the existing LED lamps , found the following defects: 1. The existing LED lamps can only emit light on one side, and the range of illumination is limited; 2. The existing LED lamps are often connected in series. If there is an open circuit in one place, the entire string of LEDs will be scrapped , causing waste

Embodiment 1

[0032] like figure 1 As shown, an LED lamp includes LED light-emitting chips 2 and a substrate 1, and the substrate 1 is made of a transparent material; The adjacent LED light-emitting chips 2 in the row are connected in series, and the LED light-emitting chips 2 are connected in parallel.

[0033] The LED lamp uses a transparent material as the substrate 1, and the light emitted by the LED light-emitting chip 2 can pass through the substrate 1 and be projected to the back of the substrate 1, thereby increasing the illumination range of the LED light-emitting chip 2.

[0034] The LED light in this embodiment adopts the method of mixed connection. If a certain LED light-emitting chip 2 is disconnected during use, it will only affect a certain row of LED light-emitting chips 2, and will not affect the entire light-emitting matrix. Make a difference without having to replace the entire LED light.

Embodiment 2

[0036] On the basis of Embodiment 1, multiple rows of LED light-emitting chips 2 form a light-emitting matrix to increase the lighting range, and at the same time, in order to further protect the LED light-emitting chips 2 and the substrate 1, the substrate 1 A fluorescent glue 3 is provided on the front, and the fluorescent glue 3 covers the LED light-emitting chip 2 .

[0037] The back of the substrate 1 is also provided with fluorescent glue 3 , and the fluorescent glue 3 on the back of the substrate 1 is symmetrical to the fluorescent glue 3 on the front of the substrate 1 . The fluorescent glue 3 is a mixture of AB glue and phosphor powder, and the AB glue and phosphor powder are mixed evenly in any proportion. On the one hand, the AB glue plays the role of cushioning and sealing; on the other hand, because the AB tape has colors, colorful LED lights can be produced.

[0038] The adjacent LED light-emitting chips 2 in the row are connected by metal wires 4 , and the rows...

Embodiment 3

[0040] This embodiment provides a production process of the LED lamp described in Embodiment 2, comprising the following steps:

[0041] Fixing the LED light-emitting chip 2 on the front surface of the substrate 1;

[0042] Using wires to electrically connect the LED light-emitting chips 2;

[0043] The fluorescent glue 3 is laid on the front and back of the substrate 1 by dispensing or molding.

[0044] The production process has the advantages of simple operation and high yield.

Abstract

The invention provides an LED lamp and a production process thereof. The LED lamp comprises LED lighting chips and a substrate, wherein the substrate is manufactured through a transparent material; the LED lighting chips are arranged in rows on the front surface of the substrate; the adjacent LED lighting chips in any row of the LED lighting chips are connected in series, and the LED lighting chip rows are connected in parallel. According to the LED lamp, the transparent material is used for manufacturing the substrate, so that the light emitted by the LED lighting chips can penetrate the substrate to be projected to the rear surface of the substrate, and as a result, the lighting ranges of the LED lighting chips can be expanded; a mixed connection manner is adopted by the LED lamp, namely, the breaking of one LED lighting chip in use can only influence the LED lighting chips in the related row, rather than influencing the whole lighting matrix, and the entire LED lamp is avoided replacing, so that the service life of the whole LED lamp is improved.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and in particular relates to an LED lamp and a production process thereof. Background technique [0002] LED lamp (LightEmittingDiode), also known as light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. LED luminescence is based on the recombination of electrons and holes in the semiconductor material under the action of current. At this time, the excess energy carried by the electrons needs to be released. If the excess energy is released in the form of electrons interacting with the lattice, phonons, heat is produced; if the excess energy is released in the form of photons, light is produced. Photon energy is the energy difference between two locations and determines the wavelength of light. [0003] Since LED lamps are more energy-saving than incandescent lamps during use and have a longer service life, the incandescent lamp...
