Abstract

The invention provides a luminescence diode lamp, which comprises a head cover, a radiator connected with the lower part of the head cover, a heat conductor and a couple of luminescence diode module groups adhibited at the lower end surface of the heat conductor; the radiator comprises a heat conducting cylinder wall and a couple of radiating rectangular fins extending outwards from the heat conducting cylinder wall; the heat radiator is contained inside the heat conducting cylinder wall and is connected with the heat conducting cylinder wall for heat conducting; the lower end surface of the heat conductor forms an inner concave used for being adhibited by the luminescence diode module groups. The air current channels between the radiating rectangular fins are arranged at the peripheral area of the heat conductor, which facilitates air taking away the heat of the radiating rectangular fins by convection from the bottom to top, thus realizing radiating effect. Meanwhile, since the luminescence diode is adhibited on the inner concave of the heat conductor, the emission angle of light is increased.

Description

technical field [0001] The invention relates to a matte color ink-jet printing paper coating and a preparation method thereof, in particular coating the coating on the color ink-jet printing paper. Background technique [0002] Color inkjet printing paper is a coated processed paper. In recent years, with the rapid development of digital technology, digital imaging technology has been rapidly improved. Due to its low cost and high image quality, inkjet printing is widely used in many fields such as advertising, office and home, and has become the main way of digital imaging. Due to the continuous innovation of inkjet printing equipment, the quality of inkjet printing has undergone a qualitative leap, which is close to the quality level of traditional photos. Compared with the replacement speed of inkjet equipment, the development of inkjet printing paper lags behind seriously. Especially in my country, the development of high-quality inkjet paper coating technology is stil...
