Definitions
- the invention relates to lighting engineering and can be used in the manufacture of lighting equipment for general outdoor and indoor lighting.
- LEDs are an effective light source, have low power consumption and long life. LEDs have high brightness with small angular dimensions. The use of LEDs as light sources without special protection from the glare of light leads to a significant '' visual load, causing discomfort and subconscious desire to leave the room with lighting devices.
- a diffuser sheath mounted on the lamp housing; hollow, light guide whose surface
- a disadvantage of the known device is that it is really possible to place only one powerful LED at the end surface of the hollow fiber, which will not be able to create a luminous flux sufficient to use the lamp as a means of general lighting .
- the LEDs of the known lamp are arranged so that the total light flux emitted by the lamp is formed by summing the direct radiation of the LEDs and the radiation,
- LED lamp comprising a light-scattering sheath mounted on a housing provided with surface cooling means;
- a reflective element whose reflective surface is concave; LEDs placed around the reflective element so that the total light flux emitted by the lamp is formed by summing the direct radiation of the LEDs and
- a converter placed in the cavity of the housing and means for connecting to an electric power circuit, for example, in the form of a threaded base (patent
- the technical result of the invention is to increase the comfort of lighting, improve the 95 uniformity of brightness of the light-emitting surface and maintaining the operating temperature of the LEDs.
- LED lamp containing a diffuser sheath made of optically transparent material / a hollow radiator in the form of a ring; concave reflector
- the surface of the reflector can be coated with particles of the same phosphor or a mixture
- the coating composition may be included phosphors with long afterglow, allowing to use the LED lamp 'achestve means evakutsionno-emergency lighting /
- LEDs can be made into; form
- correction lens or in the form of a screen
- the basic functions of all the embodiments of the light flux forming agent are: maximum utilization of the LEDs radiation and preventing direct 'LEDs inner surface exposure
- -surface screen may be 'made flat or slightly curved shape, and roughness of the reflecting surface of the screen selection can be conducted over a wide range of values: from the mirror to scatter diffusely, in. depending on the desired nature of the resulting light ⁇ flux; - as light sources can be
- LEDs that generate light including radiation in the blue and / or ultraviolet region of the spectrum, or LEDs that create white light, mostly cold
- the diffuser shell may include
- the diffuser shell may be made of a material with a diffusion transmittance. In the case of using cold white LEDs, controlling the color of the resulting luminous flux will require less phosphor, both on the reflector and in the light-scattering sheath;
- -shape diffuse shell can. be formed by arbitrarily connected surfaces, for example, planes or surfaces of revolution, combining which it is possible to control the distribution of the light flux of the LED lamp;
- figure 1 shows a diagram of the course of the rays in 180 LED lamp
- Fig. 2 shows a diagram of an LED lamp, a means of forming a luminous flux which is made in the form of an annular screen;
- Fig. 3 shows a top view of the lamp depicted
- the LED lamp comprises a diffuser shell 1 of an optically transparent material; hollow radiator 2; concave reflector 3 provided
- luminous flux forming means 5 made in the form of an annular screen installed
- radiator 2 coupled with means 7 for connecting to the power supply circuit of the radiator 2 contains internal longitudinal ribs 9, which, in addition to.
- heat sink functions are also guiding and fixing means for electronic board
- the outer surface of the radiator is equipped with cooling fins 10, the choice of surface size and shape of which depends on the amount of emitted
- the embodiments of combinations of elements of the lighting device described in the description are not exhaustive. ' They can be modified for 225 realization of specific lighting purposes.
- the structural elements of the lighting device have simple shapes that can be manufactured using known means with automated control.
