Light emitting diode lamp

Abstract

The invention discloses a light emitting diode lamp, comprising a heat radiating part, an optical part and an electrical part, wherein the optical part and the electrical part are respectively arranged on the front end and the rear end of the heat radiating part. The optical part comprises a main light source and an auxiliary light source, and light emitting diodes are adopted for the main light source and the auxiliary light source, which are pasted on a heat radiator of the heat radiating part. The electrical part comprises a shell, a circuit board and a storage battery, wherein the circuitboard and the storage battery are arranged in the shell. The circuit board is provided with an AC / DC (Alternating Current / Direct Current) conversion circuit, a charging circuit and a conversion control circuit, after an AC mains supply is converted by the AC / DC conversion circuit, a first DC voltage is outputted to charge the storage battery and supply power to the auxiliary light source, and a second DC voltage is supplied to supply power to the main light source. The auxiliary light source is switched between an auxiliary lighting state and an emergency lighting state through the conversioncontrol circuit.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a multi-functional light-emitting diode lamp with general lighting, auxiliary lighting and emergency lighting. Background technique [0002] People's long-term over-reliance on fossil fuels not only causes energy shortages and high oil prices and hinders economic development, but also increases the concentration of global carbon dioxide and harmful gas emissions, leading to climate abnormalities caused by global warming, ecological environment damage, And the harm to human survival is becoming more and more obvious. In order to sustainably manage the earth's ecological environment on which human beings depend, it is necessary to solve the energy crisis and environmental pollution problems at the same time. The development of new energy and renewable energy is the most important way to promote energy conservation and efficient use of energy. strategy, while traditional lighting consu...

Problems solved by technology

For example: the traditional emergency lighting that is widely used at present only has a single fire emergency lighting function, that is, the light is off when the power is turned on, and it is illuminated when the power is off. Look for the panic of the lights, more severe in the live crowds in public places

However, ordinary lighting fixtures do not have the function of emergency lighting, and because they need to be purchased separately, wired and installed independently, it will cause increased user cost burden and inconvenience, repeated investment of resources and waste of installation space

[0004] In addition, the application of high-power and high-brightness LEDs in the new light source of lighting must cooperate with a high-efficiency heat dissipation mechanism to minimize the junction temperature of the LEDs in order to take advantage of the above-mentioned advantages, otherwise the luminous brightness and service life of the lighting device will be greatly reduced. As far as the impact is concerned, the energy-saving effect of the lighting device will not be obvious, and it will directly impact the reliability of the lighting device, causing serious light decay and even making the lighting device invalid

Moreover, in order to cope with the reality of rising energy costs, governments of all countries have taken the promotion of energy conservation and emission reduction as an important policy and encouraged the industry to promote energy conservation in office lighting; Where necessary, other auxiliary lamps (such as desk lamps) are used for local reinforcement; however, it is still unable to improve the disadvantages of increased cost burden and inconvenience, repeated investment of resources, waste of space and affecting the overall appearance
