LED diffuse reflection light-transmittable cover and production process thereof

Abstract

The invention discloses an LED diffuse reflection light-transmittable cover and a production process thereof, comprising a glass lamp cover and a diffuse reflection film layer coated therein, characterized in that a diffuse reflection slurry film layer is prepared from polyamide resin PA, polycarbonate resin PC, curing agent, getter, glowing solution, diluent and fluorescent powder; the formulation of the diffuse reflection slurry film (by 5Kg powder as the unit) is as follows: 230-260ml of polyamide resin PA, 1800-2100ml of polycarbonate resin PC, 700-900ml of curing agent, 1800-2100ml of glowing solution, 4000-4500ml of diluent, 50-70ml of getter, and 4-5kg of fluorescent powder. The LED diffuse reflection light-transmittable cover can prevent the ultraviolet light from transmitting outwards; the cover has high light transmittance, strong adhesion, soft light and large beam angle without glare.

Description

technical field [0001] The present invention relates to the technical field of illumination, and more specifically relates to an LED translucent cover. Background technique [0002] At present, with the continuous reduction of energy and the increase of exhaust gas, people's awareness of environmental protection and energy conservation is also constantly improving. The application and development of LEDs are also issues that people from all walks of life around the world are paying attention to. In indoor and outdoor lighting equipment, LED lamps have the characteristics of energy saving, high efficiency and long life, but because LED is a laser light source, the eyes cannot directly look at it, and long-term exposure to it will damage the eyes. LED combination lamps are densely packed The light spot will produce glare and make people feel uncomfortable. Moreover, the beam angle of LED is narrow, so it can be used as directional lighting.

Problems solved by technology

In indoor and outdoor lighting equipment, LED lamps have the characteristics of energy saving, high efficiency and long life, but because LED is a laser light source, the eyes cannot directly look at it, and long-term exposure to it will damage the eyes. LED combination lamps are densely packed The light spot will produce glare and make people feel uncomfortable. Moreover, the beam angle of LED is narrow, so it can be used as directional lighting. The range of ordinary, especially indoor lighting is obviously insufficient. In order to better gather the light and make the light more concentrated , it is necessary to install a lampshade on the structure of the LED, but the LED lampshade currently on the market has low light transmittance, poor diffuse reflection effect, and large light loss
