The common led plastic strip cover materials are PC, PMMA (acrylic, plexiglass) and PCM (polycarbonate), which have the highest light transmittance, but are prone to aging and yellowing, especially under ultraviolet radiation; PMMA (polymethyl methacrylate) is easy to soften when it reaches 70 ℃, while PC is 120 ℃, so PC is more temperature resistant and heat-resistant, and its working temperature is more widely used. PC is less flammable than PMMA, and PMMA is flammable. PCM is a new composite material, which is actually a mixture of PC and PMMA. It not only keeps the characteristics of PC, but also brings the characteristics of PMMA. The price of PCM with equal weight is lower than that of PC.

PC can withstand 105 ℃ and PMMA can withstand 95 ℃. The transparency and UV resistance of PC are inferior to that of acrylic. Acrylic is not as good as PC in compression resistance and resistance. PMMA (Acrylic) and PC are the best materials for lampshade.

As LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat, low power consumption, safe low voltage working voltage, long service life, etc., and low energy consumption; Therefore, high-power led plastic strip cover is an ideal electric light source for explosion-proof lamps, especially portable explosion-proof lamps.

The utility model mainly solves the lighting problem, which comprises a lamp housing, a lamp cover arranged at the front end of the lamp housing, a luminous body and a battery arranged inside the lamp housing, and a switch arranged on the surface of the lamp housing. The utility model is characterized in that: the luminous body is a high-power LED module, and a wide voltage input driving circuit is arranged between the luminous body and the battery; The wide voltage input driving circuit includes a constant current chip, the constant current chip and the battery form a power module, the led plastic strip cover is connected to the constant current chip, and the power module and the LED module are sealed together; The lamp cover and lamp shell are welded by ultrasonic wave.

It takes advantage of the low heat value of LED to achieve intrinsically safe explosion-proof, and the led plastic strip cover source has a long life; The LED of the battery keeps constant brightness at the end of full charge and discharge; The heat dissipation device is set on the lamp shell, which can realize the effective heat dissipation of the LED module and ensure the stability of use. It is suitable for lighting in various industries such as coal mine, petroleum, railway, flood prevention, etc.
