Embodiment Construction

[0015] Figure 1 and figure 2 , the LED explosion-proof lamp of the present invention includes a housing 1 and an LED light source 2, the housing 1 is hollow, two ends of the housing 1 are provided with a cover plate 3, and one end cover plate 3 is provided with a cable inlet and outlet 4, and the LED light source 2 is connected to the aluminum substrate 5 through The LED mounting surface 101 of the housing 1 is fixed, and all the LED light sources 2 are connected in series with the constant current power supply 6, and each LED light source 2 is an LED connected in parallel with a Zener tube. In the state of high impedance, the explosion-proof lamp works normally, and when the LED lamp fails, due to the constant current power supply, the voltage applied to both ends of the LED rises to reach the critical voltage of the Zener tube, and its impedance changes suddenly, making the Zener tube conduction, thus Short-circuit the faulty LED and remove it from the entire LED circuit to ...

Abstract

An LED explosion-proof lamp comprises a casing and an LED light source. All of the LED light sources are series connection. Each LED light source is an LED connected with a zener diode in parallel. A heat radiating piece integrated with the casing and a heat radiating fin are arranged on the casing. The explosion-proof lamp is sealed wholly. The invention is a novel explosion-proof lamp taking the LED as the light source, which has long service life, good optical performance, simple circuit, small volume, safety, environment protection, power consumption. The LED light sources are connected in series. A LED damage does not influence the other LED light sources to work normally. Each component of the LED explosion-proof lamp is connected with a high sealability to achieve the protection grade IP67. A plurality of heat radiating parts are provided to ensure the LED explosion-proof lamp to work normally and stably below 55 DEG C. The installation mode is flexible and adaptable for various occasions.

Description

technical field [0001] The invention is an explosion-proof lighting device, which is an LED explosion-proof lamp. Background technique [0002] At present, there are some obvious defects in the explosion-proof lamps used in the explosive gas and dust environment in the petroleum, chemical, coal and pharmaceutical industries: large size, heavy weight, high power consumption, short life, and can not choose the light angle and irradiation distance , and the waterproof ability is weak. Contents of the invention [0003] The problem to be solved by the present invention is that the existing explosion-proof lamps cannot meet the requirements of related industries, and an explosion-proof lamp with small size, long life, low power consumption, good waterproof and easy installation is needed. [0004] The technical solution of the present invention is: LED explosion-proof lamp, including housing and LED light source, the housing is hollow, two ends of the housing are provided with...
