Table lamp with LED arc three-dimensional light guide light source

Abstract

The invention discloses an LED arc three-dimensional light guide table lamp, which comprises a light source system, a parallel rotating support system connected with the light source system and a lampstand arranged at the bottom of a rotating support, wherein the light source system comprises an aluminum alloy heat dissipation tray and a zenith sealing heat dissipation cover, the light source system comprises a light guide sheet and a circle of yellow-white two-color lamp strip arranged around the light guide sheet, a milky-white true light softening sheet is arranged on one side of the lightguide sheet, a reflective film is plated on the reverse side of the light softening sheet, a dodging film and a light softening sheet are arranged on the front side of the light guide sheet, and a light source of the lamp strip is injected into the light guide sheet, reflected by the light softening sheet, uniformly distributed by the dodging film and refined by the light softening sheet to forma conical light beam to be emitted. According to the invention, LED glare is eliminated, and a method for applying arc curvature and expanding a light source light field is created; the parallel support is simple in structure and prevents power lines from being exposed; a capacitive touch switch is designed, a moon-shaped finger groove capacitive touch switch is provided with eight lifting systempoint positions for adjusting brightness, the gear adjustment is finer and more user-friendly, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of desk lamps, in particular to a desk lamp with an LED arc three-dimensional light guide light source, in particular to a desk lamp using an LED arc three-dimensional light guide and a three-filter light source. Background technique [0002] On June 12, 2015, an international convention signed by more than 50 countries in the world specified the future development direction of light sources as light-emitting diodes, which triggered the vitality of LED's recent development.

As we all know, LED light-emitting diodes have been on the market for a long time. It is more energy-saving than various lamps and lanterns, and it has many advantages, but it still has two major defects; (1) It has glare, which will be dazzling and damage the human body. Recently, there have been more When people suffer from cataracts, glare is the culprit. Relevant experts from various countries have appealed to relevant departments to solve the problem of LED glare as soon as possible.

(2) This light source is a combination of a group of small light sources, and each light bead is a resistor that will generate heat. If no cooling device is installed, the temperature will continue to increase during operation, which will cause a vicious cycle that will affect the stability of the circuit and shorten the life of the light source. , if it is serious, the beads will be burned

Its shape is similar to that of incandescent light bulbs in the past, but it is a group or a group of LED small lamp beads, which are arranged and combined into a circular or square array, pasted on the heat-dissipating aluminum substrate and combined in series. The current adaptation circuit uses IC chips and micro-resistance capacitors, which simplifies the circuit board adaptation circuit and reduces the size. With the efforts of various LED manufacturers, the progressive reform of the intelligent mechanized production process has been realized, and the reduction has been greatly reduced. It reduces the cost of the light source and improves the luminous function. Now it can produce 50W to 250W big bulb lamps, which are widely used in large-scale enterprise assembly sites, referred to as "engineering bulb lamps". Recently, the annual production volume is doubling and increasing. The development of new light sources is more frenzied, but this new light source has a significant disadvantage, that is, there is LED glare. This light source is not a single light source, but a loose super-brightness light group. The group of light sources are not directed in the same direction, so the human eye cannot cope with it, and it is more irritating to the eyes, so it is not suitable for direct application in the field of eye protection lamps.

[0004] In order to eliminate LED glare, the lighting industry has been actively researching. At present, a kind of astigmatism sheet has appeared on the market. In fact, its effect is almost the same as that of Japanese bulb lamps. Some lighting industries simply put the astigmatism sheet in the light guide and light source combination system. To replace the uniform light film filter, we can clearly know in the practice of this experiment that its light effect is about 25% different. At present, there is no standard for astigmatism film in the country, and the worst will be more than 40%.

[0005] The second one was invented by Philips. He applied planar light guide technology to connect a group of ultra-brightness LED light-emitting beads on a metal baseband by auxiliary soldering, and surround the group of small light-bead light sources around a square or circular light source. The edge of the flat transparent plate injects the group of light into the light guide sheet and integrates it into one, and then uses a milky white soft light sheet to set off the back of the light guide sheet, so that the group of photons in the light guide sheet are all reflected in the front parallel and vertically, and then emitted Before, let the photons pass through the filter of uniform light film and soft light film, and purify them into delicate parallel luster. Light, using parallel and vertical radiation, solidifies and cannot expand the defect of the light field, which limits its comprehensive application and development
